Organization, Consolidation and Presentation of Financial Statements [Abstract]
Basis of Presentation	Basis of Presentation LendingClub Corporation (LendingClub) operates an online lending marketplace platform that connects borrowers and investors. Various wholly-owned subsidiaries of LendingClub have been established to enter into borrowing agreements with certain lenders for secured credit facilities. Additionally, LendingClub has established various entities to facilitate loan sale transactions, including sponsoring asset-backed securitization transactions and Certificate Program transactions (collectively referred to as Structured Program transactions), where certain accredited investors and qualified institutional buyers have the opportunity to invest in senior and subordinated securities backed by a pool of unsecured personal whole loans. Certificate Program transactions include CLUB Certificate and Levered Certificate transactions. LC Trust I (the LC Trust) is an independent Delaware business trust that acquires loans from LendingClub and holds them for the sole benefit of certain investors that have purchased trust certificates issued by the LC Trust that are related to specific underlying loans for the benefit of the investor. Springstone Financial, LLC (Springstone), is a wholly-owned subsidiary of LendingClub that facilitates education and patient finance loans originated by third-party issuing banks. The accompanying unaudited condensed consolidated financial statements include LendingClub, its subsidiaries (collectively referred to as the Company, we, or us) and consolidated variable interest entities (VIEs). Noncontrolling interests are reported as a separate component of consolidated equity from the equity attributable to LendingClub’s stockholders for all periods presented. All intercompany balances and transactions have been eliminated. These condensed consolidated financial statements have been prepared in conformity with accounting principles generally accepted in the United States of America (GAAP) for interim financial information and, in the opinion of management, contain all adjustments, consisting of only normal recurring adjustments, necessary for the fair statement of the results and financial position for the periods presented. These accounting principles require management to make certain estimates and assumptions that affect the amounts in the accompanying financial statements. These estimates and assumptions are inherently subjective in nature and actual results may differ from these estimates and assumptions, and the differences could be material. Results reported in interim periods are not necessarily indicative of results for the full year or any other interim period. Certain prior-period amounts have been reclassified to conform to the current period presentation. A 1-for-5 reverse stock split of the Company’s common stock became effective on July 5, 2019. As a result, prior period share and per share amounts presented in the accompanying interim condensed consolidated financial statements and these related notes were retroactively adjusted accordingly. See “ Note 4. Net Loss Per Share ” for additional information. The Company presents loans under a number of different captions to align the assets to their associated liabilities, if any. “Loans held for investment at fair value” are loans which are related to the Company’s retail notes, certificates and secured borrowings program. The Company is not exposed to market risk, interest rate risk or credit risk on these loans and all loan cash flows flow directly to the retail note, certificate and secured borrowing owners. The associated liability for this loan category is included in the caption “Notes, certificates and secured borrowings at fair value.” Loans included in “Loans held for investment by the Company at fair value” and “Loans held for sale by the Company at fair value” are loans which the Company has purchased and from which the Company earns interest income and records net fair value adjustments in earnings for changes in the valuation of loans. The accompanying interim condensed consolidated financial statements and these related notes should be read in conjunction with the consolidated financial statements and related notes included in the Company’s Annual Report on Form 10-K for the year ended December 31, 2019 (Annual Report) filed on February 19, 2020.

Accounting Policies [Abstract]
Summary of Significant Accounting Policies	Summary of Significant Accounting Policies The Company’s significant accounting policies are discussed in “ Part II – Item 8 – Financial Statements and Supplementary Data – Note 2. Summary of Significant Accounting Policies ” in the Annual Report. There have been no changes to these significant accounting policies for the three month period ended March 31, 2020 , except as noted below. Securities Available for Sale Debt securities that the Company might not hold until maturity are classified as securities available for sale. In structured program transactions that meet the applicable criteria to be accounted for as a sale, the Company retains certain asset-backed securities including subordinated residual interests and CLUB Certificates, which are classified as securities available for sale. On January 1, 2020, the entity adopted ASU 2016-13, Financial Instruments – Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments (CECL) for securities available for sale. Asset-backed securities where the expected cash flows are significantly lower than that of the contractual future cash flows are considered to be purchased with credit deterioration (PCD). The discounted differential in expected and contractual cash flows is included with the purchase price of the asset to determine amortized cost of the security with an equal and offsetting valuation allowance for credit losses. Securities available for sale are recorded at fair value and unrealized gains and losses are reported, net of taxes, in “Accumulated other comprehensive income (loss)” included in Equity in the Company’s Consolidated Balance Sheets, unless management determines that the security is impaired due to a deterioration in expected cash flows, in which case the unrealized loss is recognized in earnings within “Net fair value adjustments” as a valuation allowance for credit losses (with the implementation of CECL) or other-than-temporary impairment (prior to the implementation of CECL) in the Company’s Condensed Consolidated Statements of Operations . Management evaluates whether debt securities available for sale with unrealized losses are impaired on a quarterly basis. If the Company intends to sell the security, or if it is more likely than not that it will be required to sell the security before recovery, an impairment is recognized in earnings equal to the entire difference between the amortized cost basis and fair value of the debt security. However, even if the Company does not expect to sell a debt security it must evaluate if a deterioration in cash flows exists. Accrued Interest Receivable on Loans The Company does not record an allowance for credit losses on accrued interest receivable. The Company places loans on non-accrual status at 90 days past due. When a loan is placed on non-accrual status, the Company stops accruing interest and reverses all accrued but unpaid interest income as of such date. Net Income (Loss) Per Share Basic net income (loss) per share (Basic EPS) attributable to common stockholders is computed by dividing net income (loss) attributable to LendingClub by the weighted-average number of common shares outstanding during the period. Diluted net income (loss) per share (Diluted EPS) is computed by dividing net income (loss) attributable to LendingClub by the weighted-average number of common shares outstanding during the period, adjusted for the effects of dilutive issuances of shares of common stock, which include incremental shares issued for outstanding RSUs, PBRSUs, and stock options. PBRSUs are included in dilutive shares to the extent the pre-established performance targets have been or are estimated to be satisfied as of the reporting date. The dilutive potential common shares are computed using the treasury stock method. The effects of outstanding RSUs, PBRSUs, and stock options are excluded from the computation of Diluted EPS in periods in which the effect would be antidilutive. For periods with more than one class of common shares, the Company computes Basic and Diluted EPS using the two-class method, which is an allocation of net income (loss) among the holders of each class of common shares. The Series A Preferred Stock is considered a separate class of common share for purposes of calculating net income (loss) per share because it participates in earnings similar to common stock and does not receive any significant preferences over the common stock. Beneficial Conversion Feature The Company accounts for the beneficial conversion feature (BCF) on its Series A Preferred Stock in accordance with ASC 470-20, Debt with Conversion and Other Options . The Company accretes the BCF discount from the date of issuance to the earliest conversion date, which was March 20, 2020. All of the BCF discount was accreted and recognized as a deemed dividend in “Accumulated deficit” on the Company’s Condensed Consolidated Balance Sheets. See “ Note 14. Stockholders' Equity ” for additional information. Adoption of New Accounting Standards The Company adopted the following accounting standards during the three month period ended March 31, 2020 : On January 1, 2020, the entity adopted ASU 2016-13, Financial Instruments – Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments . For loans accounted for at amortized cost, the guidance replaces the incurred loss impairment methodology with an expected credit loss model for which a company recognizes an allowance based on the estimate of expected credit loss. As the Company has elected the fair value option for loans and loans accounted for at fair value through net income are outside the scope of Topic 326, there is no impact on the Company’s loan portfolios. For debt securities available for sale, Topic 326 requires recognition of expected credit losses by recognizing an allowance for credit losses when the fair value of the security is below amortized cost and the recognition of this allowance is limited to the difference between the security’s amortized cost basis and fair value. Upon adoption, the amendments in Topic 326 are recognized through a cumulative-effect adjustment to retained earnings, except for debt securities with prior other-than-temporary impairment whereby Topic 326 is applied prospectively. The Company adopted ASC 326 using the prospective transition approach for debt securities for which other-than-temporary impairment had been recognized prior to January 1, 2020. As a result, the amortized cost basis remains the same before and after the effective date of ASC 326. The effective interest rate on these debt securities was not changed. Amounts previously recognized in accumulated other comprehensive income as of January 1, 2020 relating to improvements in cashflows expected to be collected are accreted into income over the remaining life of the asset. Recoveries of amounts previously written off relating to improvements in cash flows after January 1, 2020 are recorded in earnings when received. Additionally, the Company adopted ASC 326 using the prospective transition approach for PCD financial assets. The Company did not have any previously classified assets as purchased credit impaired (PCI) under ASC 310-30. In accordance with this standard, management did not reevaluate for PCD upon transition. Adoption of Topic 326 did not have an impact on the Company’s financial position, results of operations, and cash flows. The Company did not record a cumulative effect adjustment to retained earnings. The Company included the disclosures required by ASU 2016-13 in “ Note 5. Securities Available for Sale . ” In August 2018, the FASB issued ASU 2018-13, Fair Value Measurement (Topic 820): Disclosure Framework – Changes to the Disclosure Requirements for Fair Value Measurement , which modifies the disclosure requirements on fair value measurements by removing, modifying, or adding certain disclosures. The ASU eliminates such disclosures as the amount of and reasons for transfers between Level 1 and Level 2 of the fair value hierarchy and valuation processes for Level 3 fair value measurements. The ASU adds new disclosure requirements for Level 3 measurements. The new guidance became effective on January 1, 2020 and did not have a material impact on the Company’s related disclosures. In August 2018, the FASB issued ASU 2018-15, Intangibles – Goodwill and Other – Internal-Use Software – (Subtopic 350-40): Customer’s Accounting for Implementation Costs Incurred in a Cloud Computing Arrangement That Is a Service Contract , which requires a customer in a hosting arrangement that is a service contract to follow the internal-use software guidance in ASC 350-40 to determine which implementation costs to capitalize as assets or expense as incurred. The standard became effective on January 1, 2020 and the Company adopted the standard using the prospective approach. The Company has reviewed existing cloud computing arrangements and determined which ones are service contracts. Implementation costs that are not from internal developers related to service contracts that satisfy the criteria for capitalization under ASC 350-40 will be presented with “Other assets” on the Company’s Consolidated Balance Sheets, amortization expense will be presented in the same line on the income statement as the fees for the associated hosted service on the Company’s Consolidated Statements of Operations, and the cash flows will be presented consistent with the presentation of cash flows for the fees related to the hosted service, generally as cash flows from operations, on the Company’s Consolidated Statements of Cash Flows. Adoption of the standard did not have a material impact on the Company’s financial position, results of operations, cash flows, or disclosures. New Accounting Standards Not Yet Adopted In December 2019, the FASB issued ASU 2019-12, Income Taxes (Topic 740): Simplifying the Accounting for Income Taxes , which is part of the FASB’s initiative to reduce complexity in accounting standards. The proposed ASU eliminates certain exceptions to the general principles of ASC 740, Income Taxes , and simplifies income tax accounting in several areas. The standard is effective on January 1, 2021 with early adoption permitted. The Company is evaluating the impact this ASU will have on its financial position, results of operations, cash flows, and disclosures, but does not expect such adoption to have a material impact. In March 2020, the FASB issued ASU 2020-04, Reference Rate Reform (Topic 848): Facilitation of the Effects of Reference Rate Reform on Financial Reporting, which, if certain criteria are met, provides optional expedients and exceptions for applying generally accepted accounting principles to transactions affected by reference rate reform. These transactions include contract modifications, hedging relationships, and sale or transfer of debt securities classified as held-to-maturity. The provisions of the new standard may be adopted as of the beginning of the reporting period when the election is made until December 31, 2022. The Company is evaluating the impact this ASU will have on its financial position, results of operations, cash flows, and disclosures. The Company has not elected an adoption date.

Referral fees are presented as a component of “Other revenue” in the Condensed Consolidated Statements of Operations . The following table presents the Company’s revenue from contracts with customers, disaggregated by revenue source for services transferred over time, for the first quarters of 2020 and 2019 : Three Months Ended 2020 2019 Transaction fees $ 136,243 $ 135,397 Referral fees 1,614 695 Total revenue from contracts with customers $ 137,857 $ 136,092 The Company recognizes transaction and referral fees at each distinct instance after the Company satisfies its performance obligations. The Company had no bad debt expense for the first quarters of 2020 and 2019 . Because revenue is recognized at the same time that payments are received, the Company had no contract assets, contract liabilities, or deferred contract costs recorded as of both March 31, 2020 and December 31, 2019 . Additionally, the Company did not recognize any revenue from performance obligations related to prior periods (for example, due to changes in transaction price) for the first quarters of 2020 and 2019 .

(3) Share and per share information has been retroactively adjusted, as applicable, to reflect the reverse stock split discussed below. In February 2020, the Company entered into an exchange agreement with its largest stockholder, Shanda Asset Management Holdings Limited and its affiliates (Shanda), pursuant to which, on March 20, 2020, Shanda exchanged all of 19,562,881 shares of LendingClub common stock, par value of $0.01 per share, held by it for (i) 195,628 newly issued shares of mandatorily convertible, non-voting, LendingClub preferred stock, series A (Series A Preferred Stock), par value of $0.01 per share, and (ii) a one-time cash payment of $50.2 million . The Series A Preferred Stock is considered a separate class of common shares for purposes of calculating net income (loss) per share because it participates in earnings similar to common stock and does not receive any significant preferences over the common stock. See “ Note 14. Stockholders' Equity ,” for additional information. During the period that included the Company’s preferred stock, Basic and Diluted EPS were computed using the two-class method, which is a net income (loss) allocation that determines EPS for each class of common stock according to dividends declared and participation rights in undistributed income (loss). The following table summarizes the weighted-average common stock that were excluded from the Company’s diluted net income (loss) per share computation because their effect would have been anti-dilutive for the periods presented: Three Months Ended 2020 2019 Preferred stock 2,579,710 — Stock options 283,201 882,661 RSUs and PBRSUs 30,852 118,681 Total (1) 2,893,763 1,001,342 (1) Share information has been retroactively adjusted, as applicable, to reflect the reverse stock split discussed below.

Investments, Debt and Equity Securities [Abstract]
Securities Available for Sale	Securities Available for Sale The Company’s Structured Program transactions include (i) asset-backed securitization transactions and (ii) Certificate Program transactions. Certificate Program transactions include CLUB Certificate and Levered Certificate transactions. In connection with asset-backed securitizations, the Company is the sponsor and establishes trusts to ultimately purchase the unsecured personal loans from the Company and/or third-party whole loan investors. Securities issued from our asset-backed securitizations are senior or subordinated based on the waterfall criteria of loan payments to each security class. The subordinated residual interests issued from these transactions are first to absorb credit losses in accordance with the waterfall criteria. The assets are transferred into a trust such that the assets are legally isolated from the creditors of the Company and are not available to satisfy obligations of the Company. These assets can only be used to settle obligations of the underlying trusts. The asset-backed securitization senior securities and subordinated residual interests retained by the Company are presented as “Asset-backed senior securities” and “Asset-backed subordinated securities,” respectively, in the securities available for sale tables below. In addition, the Company sponsors the sale of unsecured personal loans through the issuance of certificate securities under our Certificate Program. The certificate securities are collateralized by loans transferred to a series of a master trust and trade in the over-the-counter market with a CUSIP. The assets are transferred into a trust such that the assets are legally isolated from the creditors of the Company and are not available to satisfy obligations of the Company. These assets can only be used to settle obligations of the underlying Certificate Program trusts. The CLUB Certificate issued securities are pass-through securities of which each owner has an undivided and equal interest in the underlying loans of each transaction. The Levered Certificate issued securities include senior and subordinated securities based on the waterfall criteria of loan payments to each security class. The subordinated securities issued from these transactions are first to absorb credit losses in accordance with the waterfall criteria. The CLUB Certificate issued securities retained by the Company are presented as “CLUB Certificate asset-backed securities” in the securities available for sale tables below. The Levered Certificate issued senior and subordinated securities retained by the Company are presented in aggregate with securities from asset-backed securitizations as “Asset-backed senior securities” and “Asset-backed subordinated securities,” respectively, in the tables below. The “Other asset-backed securities” caption in the tables below primarily includes investment-grade rated bonds that are collateralized by automobile loan receivables.

The Company recorded an allowance for credit loss on those securities where there was a deterioration in future estimated cash flows. The Company also recorded unrealized losses on securities with fair value price reductions due to higher liquidity premiums observed due to the market dislocation related to the COVID-19 pandemic. The Company deemed it not necessary to record unrealized losses as an allowance for credit loss for certain securities due to the nature of those securities and their investment grade quality. During the first quarters of 2020 and 2019 , the Company recognized $11.0 million in credit loss expense and $1.2 million in other-than-temporary impairment charges, respectively, on its asset-backed securities related to Structured Program transactions.

Additionally, the assets and liabilities in the table below exclude intercompany balances that eliminate in consolidation: March 31, 2020 Consolidated VIEs Unconsolidated VIEs Total Assets Restricted cash $ 36,783 $ — $ 36,783 Securities available for sale at fair value — 203,275 203,275 Loans held for investment at fair value 133,701 — 133,701 Loans held for investment by the Company at fair value 70,426 — 70,426 Loans held for sale by the Company at fair value 635,005 — 635,005 Accrued interest receivable 5,144 123 5,267 Other assets 1,451 51,682 53,133 Total assets $ 882,510 $ 255,080 $ 1,137,590 Liabilities Accrued interest payable $ 2,761 $ — $ 2,761 Accrued expenses and other liabilities 232 — 232 Notes, certificates and secured borrowings at fair value 133,701 — 133,701 Payable to Structured Program note and certificate holders at fair value 206,092 — 206,092 Credit facilities and securities sold under repurchase agreements 390,026 — 390,026 Total liabilities 732,812 — 732,812 Total net assets $ 149,698 $ 255,080 $ 404,778 December 31, 2019 Consolidated VIEs Unconsolidated VIEs Total Assets Restricted cash $ 30,046 $ — $ 30,046 Securities available for sale at fair value — 220,135 220,135 Loans held for investment at fair value 197,842 — 197,842 Loans held for investment by the Company at fair value 40,251 — 40,251 Loans held for sale by the Company at fair value 551,455 — 551,455 Accrued interest receivable 4,431 877 5,308 Other assets 1,359 52,098 53,457 Total assets $ 825,384 $ 273,110 $ 1,098,494 Liabilities Accrued interest payable $ 3,185 $ — $ 3,185 Accrued expenses and other liabilities 244 — 244 Notes, certificates and secured borrowings at fair value 197,842 — 197,842 Payable to Structured Program note and certificate holders at fair value 40,610 — 40,610 Credit facilities and securities sold under repurchase agreements 387,251 — 387,251 Total liabilities 629,132 — 629,132 Total net assets $ 196,252 $ 273,110 $ 469,362 Consolidated VIEs The Company consolidates VIEs when it is deemed to be the primary beneficiary. See “ Part II – Item 8. Financial Statements and Supplementary Data – Notes to Consolidated Financial Statements – Note 2. Summary of Significant Accounting Policies ” in the Annual Report for additional information. LC Trust The Company established the LC Trust for the purpose of acquiring and holding loans for the sole benefit of certain investors that have purchased trust certificates issued by the LC Trust. The Company is obligated to ensure that the LC Trust meets minimum capital requirements with respect to funding the administrative activities and maintaining the operations of the LC Trust. Consolidated Trusts The Company establishes trusts to facilitate the sale of loans and issuance of senior and subordinated securities. If the Company is the primary beneficiary of the trust, it is a consolidated VIE and will reflect senior and subordinated securities held by third parties as a “Payable to Structured Program note and certificate holders at fair value” in the Company’s Condensed Consolidated Balance Sheets . If subsequently the Company is not the primary beneficiary of the trust, the Company will deconsolidate the VIE. See “ Note 13. Debt ” for additional information. Warehouse Credit Facilities The Company established certain entities (deemed to be VIEs) to enter into warehouse credit facilities for the purpose of purchasing loans from LendingClub. See “ Note 13. Debt ” for additional information. The following tables present a summary of financial assets and liabilities from the Company’s involvement with consolidated VIEs at March 31, 2020 and December 31, 2019 : March 31, 2020 Assets Liabilities Net Assets LC Trust $ 137,089 $ (134,876 ) $ 2,213 Consolidated trusts 219,259 (206,571 ) 12,688 Warehouse credit facilities 526,162 (391,365 ) 134,797 Total consolidated VIEs $ 882,510 $ (732,812 ) $ 149,698 December 31, 2019 Assets Liabilities Net Assets LC Trust $ 201,696 $ (199,520 ) $ 2,176 Consolidated trusts 43,300 (40,687 ) 2,613 Warehouse credit facilities 580,388 (388,925 ) 191,463 Total consolidated VIEs $ 825,384 $ (629,132 ) $ 196,252 The creditors of the VIEs above have no recourse to the general credit of the Company as the primary beneficiary of the VIEs and the liabilities of the VIEs can only be settled by the respective VIE’s assets. Unconsolidated VIEs The Company’s transactions with unconsolidated VIEs include asset-backed securitizations, Certificate Program transactions and loan sale transactions of unsecured personal loans. The Company has various forms of involvement with VIEs, including servicing of loans and holding senior or subordinated residual interests in the VIEs. The accounting for these transactions is based on a primary beneficiary analysis to determine whether the underlying VIEs should be consolidated. If the VIEs are not consolidated and the transfer of the loans from the Company to the VIE meets sale accounting criteria, then the Company will recognize a gain or loss on sales of loans. The Company considers continued involvement in an unconsolidated VIE insignificant if it is the sponsor and servicer and does not hold other significant variable interests. In these instances, the Company’s involvement with the VIE is in the role as an agent and without significant participation in the economics of the VIE. The Company enters into separate servicing agreements with the VIEs and holds at least 5% of the beneficial interests issued by the VIEs to comply with regulatory risk retention rules. The beneficial interests retained by the Company consist of senior securities and subordinated securities and are accounted for as securities available for sale. In connection with these transactions, we make certain customary representations, warranties and covenants. See “ Part II – Item 8. Financial Statements and Supplementary Data – Notes to Consolidated Financial Statements – Note 2. Summary of Significant Accounting Policies ” in the Annual Report for additional information. Investment Fund The Company has an equity investment in a private fund (Investment Fund) that participates in a family of funds with other unrelated third parties. This family of funds purchases whole loans and interests in loans from the Company, as well as other assets from third parties unrelated to the Company. As of March 31, 2020 , the Company had an ownership interest of approximately 22% in the Investment Fund. The Company’s investment is deemed to be a variable interest in the Investment Fund because the Company shares in the expected returns and losses of the Investment Fund. At March 31, 2020 , the Company’s investment was $7.8 million , which is recognized in “Other assets” on the Company’s Condensed Consolidated Balance Sheets . The following tables summarize unconsolidated VIEs with which the Company has significant continuing involvement, but is not the primary beneficiary at March 31, 2020 and December 31, 2019 : March 31, 2020 Carrying Value Total VIE Assets Securities Available for Sale Accrued Interest Receivable Other Assets Accrued Expenses and Other Liabilities Securities Sold Under Repurchase Agreements Net Assets Unconsolidated Trusts $ 1,927,322 $ 74,603 $ 69 $ 17,989 $ — $ — $ 92,661 Certificate Program 2,846,051 128,672 54 25,918 — — 154,644 Investment Fund 34,585 — — 7,775 — — 7,775 Total unconsolidated VIEs $ 4,807,958 $ 203,275 $ 123 $ 51,682 $ — $ — $ 255,080 March 31, 2020 Maximum Exposure to Loss Securities Available for Sale Accrued Interest Receivable Other Assets Accrued Expenses and Other Liabilities Securities Sold Under Repurchase Agreements Total Exposure Unconsolidated Trusts $ 74,603 $ 69 $ 17,989 $ — $ — $ 92,661 Certificate Program 128,672 54 25,918 — — 154,644 Investment Fund — — 7,775 — — 7,775 Total unconsolidated VIEs $ 203,275 $ 123 $ 51,682 $ — $ — $ 255,080 December 31, 2019 Carrying Value Total VIE Assets Securities Available for Sale Accrued Interest Receivable Other Assets Accrued Expenses and Other Liabilities Securities Sold Under Repurchase Agreements Net Assets Unconsolidated Trusts $ 1,909,219 $ 93,881 $ 362 $ 18,768 $ — $ — $ 113,011 Certificate Program 2,585,957 126,254 515 25,588 — — 152,357 Investment Fund 34,170 — — 7,742 — — 7,742 Total unconsolidated VIEs $ 4,529,346 $ 220,135 $ 877 $ 52,098 $ — $ — $ 273,110 December 31, 2019 Maximum Exposure to Loss Securities Available for Sale Accrued Interest Receivable Other Assets Accrued Expenses and Other Liabilities Securities Sold Under Repurchase Agreements Total Exposure Unconsolidated Trusts $ 93,881 $ 362 $ 18,768 $ — $ — $ 113,011 Certificate Program 126,254 515 25,588 — — 152,357 Investment Fund — — 7,742 — — 7,742 Total unconsolidated VIEs $ 220,135 $ 877 $ 52,098 $ — $ — $ 273,110 “Total VIE Assets” represents the remaining principal balance of loans held by unconsolidated VIEs with respect to Unconsolidated Trusts, Certificate Program transactions, and the net assets held by the Investment Fund using the most current information available. “Securities Available for Sale,” “Accrued Interest Receivable,” “Other Assets” and “Accrued Expenses and Other Liabilities” are the balances in the Company’s Condensed Consolidated Balance Sheets related to its involvement with the unconsolidated VIEs. “Other Assets” includes the Company’s servicing assets and servicing receivables and the Company’s equity investment with respect to the Investment Fund. “Total Exposure” refers to the Company’s maximum exposure to loss from its involvement with unconsolidated VIEs. It represents estimated loss that would be incurred under severe, hypothetical circumstances, for which the Company believes the possibility is extremely remote, such as where the value of interests and any associated collateral declines to zero. Accordingly, this required disclosure is not an indication of expected losses. The following table summarizes activity related to the Unconsolidated Trusts and Certificate Program trusts, with the transfers accounted for as a sale on the Company’s condensed consolidated financial statements for the first quarters of 2020 and 2019 : Three Months Ended March 31, 2020 2019 Unconsolidated Trusts Unconsolidated Certificate Program Trusts Unconsolidated Trusts Unconsolidated Certificate Program Trusts Principal derecognized from loans securitized or sold $ 255,203 $ 637,637 $ 293,419 $ 541,128 Net gains (losses) recognized from loans securitized or sold $ (20 ) $ 5,596 $ 2,932 $ 5,824 Fair value of asset-backed senior and subordinated securities, and CLUB Certificate asset-backed securities retained upon settlement (1) $ 12,707 $ 31,423 $ 14,555 $ 26,787 Cash proceeds from loans securitized or sold $ 237,764 $ 598,515 $ 266,235 $ 513,885 Cash proceeds from servicing and other administrative fees on loans securitized or sold $ 5,121 $ 6,992 $ 3,570 $ 2,943 Cash proceeds for interest received on senior securities and subordinated securities $ 1,040 $ 2,273 $ 1,439 $ 1,435 (1) For Structured Program transactions, the Company retained asset-backed senior securities of $23.0 million and $13.4 million , CLUB Certificate asset-backed securities of $18.3 million and $26.8 million , and asset-backed subordinated securities of $2.9 million and $1.1 million for the first quarters of 2020 and 2019 , respectively. Off-Balance Sheet Loans Off-balance sheet loans primarily relate to Structured Program transactions for which the Company has some form of continuing involvement, including as servicer. Delinquent loans are comprised of loans 31 days or more past due, including non-accrual loans. Loans to eligible borrowers participating in Skip-a-Pay are not considered delinquent during the commensurate period the loan is extended. For loans related to Structured Program transactions where servicing is the only form of continuing involvement, the Company would only experience a loss if it was required to repurchase a loan due to a breach in representations and warranties associated with its loan sale or servicing contracts. As of March 31, 2020 , the aggregate unpaid principal balance of the off-balance sheet loans pursuant to Structured Program transactions was $4.8 billion , of which $144.4 million was attributable to off-balance sheet loans that were 31 days or more past due. As of December 31, 2019 , the aggregate unpaid principal balance of the off-balance sheet loans pursuant to Structured Program transactions was $4.4 billion , of which $145.6 million was attributable to off-balance sheet loans that were 31 days or more past due. Retained Interests from Unconsolidated VIEs The Company and other investors in the subordinated interests issued by trusts and Certificate Program trusts have rights to cash flows only after the investors holding the senior securities issued by the trusts have first received their contractual cash flows. The investors and the trusts have no direct recourse to the Company’s assets, and holders of the securities issued by the trusts can look only to the assets of the securitization trusts that issued their securities for payment. The beneficial interests held by the Company are subject principally to the credit and prepayment risk stemming from the underlying unsecured personal whole loans. See “ Note 8. Fair Value of Assets and Liabilities ” for additional information on the fair value sensitivity of asset-backed securities related to Structured Program transactions.

Fair Value of Assets and Liabilities	Fair Value of Assets and Liabilities For a description of the fair value hierarchy and the Company’s fair value methodologies, see “ Part II – Item 8. Financial Statements and Supplementary Data – Note 2. Summary of Significant Accounting Policies ” in the Annual Report. The Company records certain assets and liabilities at fair value as listed in the following tables. Financial Instruments, Assets and Liabilities Recorded at Fair Value The following tables present the fair value hierarchy for assets and liabilities measured at fair value at March 31, 2020 and December 31, 2019 : March 31, 2020 Level 1 Inputs Level 2 Inputs Level 3 Inputs Balance at Fair Value Assets: Loans held for investment $ — $ — $ 885,413 $ 885,413 Loans held for investment by the Company — — 71,003 71,003 Loans held for sale by the Company — — 741,704 741,704 Securities available for sale: Asset-backed senior securities and subordinated securities — 99,764 16,676 116,440 CLUB Certificate asset-backed securities — — 86,835 86,835 Corporate debt securities — 17,279 — 17,279 Commercial paper — 13,126 — 13,126 Other asset-backed securities — 11,999 — 11,999 Certificates of deposit — 10,875 — 10,875 Total securities available for sale — 153,043 103,511 256,554 Servicing assets — — 92,825 92,825 Total assets $ — $ 153,043 $ 1,894,456 $ 2,047,499 Liabilities: Notes, certificates and secured borrowings $ — $ — $ 886,840 $ 886,840 Payable to Structured Program note and certificate holders — — 206,092 206,092 Deferred revenue — — 8,541 8,541 Loan trailing fee liability — — 10,372 10,372 Total liabilities $ — $ — $ 1,111,845 $ 1,111,845 December 31, 2019 Level 1 Inputs Level 2 Inputs Level 3 Inputs Balance at Assets: Loans held for investment $ — $ — $ 1,079,315 $ 1,079,315 Loans held for investment by the Company — — 43,693 43,693 Loans held for sale by the Company — — 722,355 722,355 Securities available for sale: Asset-backed senior securities and subordinated securities — 109,339 21,090 130,429 CLUB Certificate asset-backed securities — — 89,706 89,706 Corporate debt securities — 14,343 — 14,343 Certificates of deposit — 13,100 — 13,100 Other asset-backed securities — 12,080 — 12,080 Commercial paper — 9,274 — 9,274 U.S. agency securities — 1,995 — 1,995 Total securities available for sale — 160,131 110,796 270,927 Servicing assets — — 89,680 89,680 Total assets $ — $ 160,131 $ 2,045,839 $ 2,205,970 Liabilities: Notes, certificates and secured borrowings $ — $ — $ 1,081,466 $ 1,081,466 Payable to Structured Program note and certificate holders — — 40,610 40,610 Loan trailing fee liability — — 11,099 11,099 Total liabilities $ — $ — $ 1,133,175 $ 1,133,175 As presented in the tables above, the Company has elected the fair value option for certain liabilities. Changes in the fair value of these financial liabilities caused by a change in the Company’s risk are reported in other comprehensive income (OCI). For the first quarter of 2020 , the amount reported in OCI is zero because these financial liabilities are either payable only upon receipt of cash flows from underlying loans or secured by cash collateral. Financial instruments are categorized in the valuation hierarchy based on the significance of unobservable factors in the overall fair value measurement. Since the Company’s loans held for investment and related notes, certificates, and secured borrowings, loans held for sale, loan servicing rights, asset-backed securities related to Structured Program transactions, and loan trailing fee liability do not trade in an active market with readily observable prices, the Company uses significant unobservable inputs to measure the fair value of these assets and liabilities. These fair value estimates may also include observable, actively quoted components derived from external sources. As a result, changes in fair value for assets and liabilities within the Level 2 or Level 3 categories may include changes in fair value that were attributable to observable and unobservable inputs, respectively. The Company primarily uses a discounted cash flow model to estimate the fair value of Level 3 instruments based on the present value of estimated future cash flows. This model uses inputs that are inherently judgmental and reflect our best estimates of the assumptions a market participant would use to calculate fair value. The Company did not transfer any assets or liabilities in or out of Level 3 during the first quarter of 2020 or the year ended December 31, 2019 . Fair valuation adjustments are recorded through earnings related to Level 3 instruments for the first quarter of 2020 and 2019 . Certain unobservable inputs may (in isolation) have either a directionally consistent or opposite impact on the fair value of the financial instrument for a given change in that input. When multiple inputs are used within the valuation techniques, a change in one input in a certain direction may be offset by an opposite change from another input. Loans Held for Investment, Notes, Certificates and Secured Borrowings Significant Unobservable Inputs The following table presents quantitative information about the significant unobservable inputs used for the Company’s Level 3 fair value measurements for loans held for investment, notes, certificates and secured borrowings at March 31, 2020 and December 31, 2019 : Loans Held for Investment, Notes, Certificates and Secured Borrowings March 31, 2020 December 31, 2019 Minimum Maximum Weighted- Average Minimum Maximum Weighted- Average Discount rates 7.7 % 15.2 % 9.8 % 6.0 % 12.0 % 7.9 % Net cumulative expected loss rates (1) 5.6 % 29.9 % 14.7 % 3.6 % 34.9 % 11.9 % Cumulative expected prepayment rates (1) 18.2 % 36.9 % 22.6 % 28.7 % 38.6 % 31.7 % (1) Expressed as a percentage of the original principal balance of the loan, note, certificate or secured borrowing. Significant Recurring Level 3 Fair Value Input Sensitivity At March 31, 2020 and December 31, 2019 , the discounted cash flow methodology used to estimate the note, certificate and secured borrowings’ fair values used the same projected net cash flows as their related loans. As demonstrated by the following tables, the fair value adjustments for loans held for investment and loans held for sale were largely offset by the corresponding fair value adjustments due to the payment dependent design of the notes, certificates and secured borrowings. Fair Value Reconciliation The following tables present additional information about Level 3 loans held for investment, loans held for sale, and notes, certificates and secured borrowings measured at fair value on a recurring basis for the first quarters of 2020 and 2019 : Loans Held for Investment Loans Held for Sale Notes, Certificates and Secured Borrowings Outstanding Principal Balance Valuation Adjustment Fair Value Outstanding Principal Balance Valuation Adjustment Fair Value Outstanding Principal Balance Valuation Adjustment Fair Value Balance at December 31, 2019 $ 1,148,888 $ (69,573 ) $ 1,079,315 $ — $ — $ — $ 1,148,888 $ (67,422 ) $ 1,081,466 Purchases 104,620 — 104,620 464,828 (1,879 ) 462,949 — — — Transfers (to) from loans held for investment and/or loans held for sale (17,478 ) — (17,478 ) 17,413 — 17,413 — — — Issuances — — — — — — 104,620 — 104,620 Sales — — — (482,241 ) 2,239 (480,002 ) — — — Principal payments and retirements (215,748 ) — (215,748 ) — — — (233,226 ) — (233,226 ) Charge-offs, net of recoveries (29,620 ) 17,311 (12,309 ) — — — (29,620 ) 16,431 (13,189 ) Change in fair value recorded in earnings — (52,987 ) (52,987 ) — (360 ) (360 ) — (52,831 ) (52,831 ) Balance at March 31, 2020 $ 990,662 $ (105,249 ) $ 885,413 $ — $ — $ — $ 990,662 $ (103,822 ) $ 886,840 Loans Held for Investment Loans Held for Sale Notes, Certificates and Secured Borrowings Outstanding Principal Balance Valuation Adjustment Fair Value Outstanding Principal Balance Valuation Adjustment Fair Value Outstanding Principal Balance Valuation Adjustment Fair Value Balance at December 31, 2018 $ 2,013,438 $ (130,187 ) $ 1,883,251 $ — $ — $ — $ 2,033,258 $ (127,383 ) $ 1,905,875 Purchases 193,092 (21 ) 193,071 563,036 — 563,036 — — — Transfers (to) from loans held for investment and/or loans held for sale (223 ) — (223 ) — — — — — — Issuances — — — — — — 193,092 — 193,092 Sales — — — (563,036 ) (1,165 ) (564,201 ) — — — Principal payments and retirements (340,444 ) — (340,444 ) — — — (360,487 ) 14 (360,473 ) Charge-offs, net of recoveries (60,785 ) 46,876 (13,909 ) — — — (60,785 ) 46,876 (13,909 ) Change in fair value recorded in earnings — (23,548 ) (23,548 ) — 1,165 1,165 — (21,359 ) (21,359 ) Balance at March 31, 2019 $ 1,805,078 $ (106,880 ) $ 1,698,198 $ — $ — $ — $ 1,805,078 $ (101,852 ) $ 1,703,226 Loans Invested in by the Company Significant Unobservable Inputs The following table presents quantitative information about the significant unobservable inputs used for the Company’s Level 3 fair value measurements for loans invested in by the Company at March 31, 2020 and December 31, 2019 : Loans Invested in by the Company March 31, 2020 December 31, 2019 Minimum Maximum Weighted- Minimum Maximum Weighted- Discount rates 5.0 % 15.2 % 9.3 % 6.0 % 11.5 % 7.8 % Net cumulative expected loss rates (1) 6.8 % 35.7 % 16.2 % 3.6 % 36.6 % 10.9 % Cumulative expected prepayment rates (1) 21.2 % 20.6 % 18.8 % 27.3 % 41.0 % 31.6 % (1) Expressed as a percentage of the original principal balance of the loan.

Debt	3 Months Ended

Debt Disclosure [Abstract]
Debt	Debt Credit Facilities and Securities Sold Under Repurchase Agreements The Company may enter into arrangements in the ordinary course of business pursuant to which the Company can incur indebtedness. Below is a description of certain of these arrangements: Warehouse Credit Facilities Through wholly-owned subsidiaries, the Company entered into secured warehouse credit facilities (Warehouse Facilities), starting in 2017, to finance the Company’s personal loans and auto refinance loans and to pay fees and expenses related to the applicable facilities. Each subsidiary entered into a credit agreement and security agreement with a commercial bank as administrative agent and a national banking association as collateral trustee and paying agent. The creditors of the Warehouse Facilities have no recourse to the general credit of the Company. As of March 31, 2020 , the warehouse facilities used to finance our personal loans (Personal Loan Warehouse Credit Facilities) have a combined borrowing capacity of $750.0 million on a revolving basis and have “Commitment Termination Dates” ranging from June 2020 to February 2022, at which point the Company’s ability to borrow new funds under the respective facility ends. Under the respective agreements, if not amended, extended, or replaced, any outstanding debt on the Commitment Termination Dates would be repaid as an amortizing term loan (based on principal repayments of the financed personal loans) until the facility’s final maturity date, and outstanding debt is not due in full upon the “Commitment Termination Dates.” In addition, under the respective agreements, if there is any breach of delinquency measures and other maintenance provisions, any outstanding debt would be repaid as an amortizing term loan (based on principal repayments of the financed personal loans) until the facility’s final maturity date. The final maturity date occurs at the earlier of twelve months after the Commitment Termination Date and three years after these Personal Loan Warehouse Credit Facilities were executed, and any remaining debt is due in full at such time. Under the respective agreements, the Personal Loan Warehouse Credit Facilities mature between June 2021 and February 2023. There is an outstanding balance of $378.5 million at March 31, 2020 , with associated Commitment Termination Dates of October 2020 for $144.5 million and February 2022 for $234.0 million . The credit facility, with a Commitment Maturity Date of June 2020, has no outstanding debt and is not expected to be renewed, as it supported capital markets Structured Program activity in which the Company is not currently engaged. If the Commitment Termination Dates are not extended, the outstanding credit facility balances are paid down as principal payments are received on the underlying loans securing the Personal Loan Warehouse Credit Facilities through to the final maturity date one year following the Commitment Termination Date. One of the Personal Loan Warehouse Credit Facilities with a Commitment Termination Date of February 2022 and an outstanding balance of $234.0 million at March 31, 2020 contains a loan aging limit of 210 days , after which the advance rate for any such loan is reduced by 50% . The loan aging limit is applied loan by loan, with the majority of the loans reaching their limit in the fourth quarter of 2020. Any such loans may be removed from this warehouse facility upon repayment of the borrowed amount or substitution of other qualifying loans, and could be pledged to another warehouse facility’s available unused borrowing capacity. The warehouse facility to finance auto refinance loans (Auto Loan Warehouse Credit Facility) is a $34.2 million term loan that matures in June 2021, which has a remaining outstanding balance of $11.5 million as of March 31, 2020 . The amount borrowed under this Auto Loan Warehouse Credit Facility amortizes over time through regular principal and interest payments collected from the auto refinance loans that serve as collateral. The creditors of the Personal Loan and Auto Loan Warehouse Credit Facilities have no recourse to the general credit of the Company. Borrowings under these facilities bear interest at an annual benchmark rate of LIBOR (London Inter-bank Offered Rate) or at an alternative commercial paper rate (which is either (i) the per annum rate equivalent to the weighted-average of the per annum rates at which all commercial paper notes were issued by certain lenders to fund advances or maintain loans, or (ii) the daily weighted-average of LIBOR, as set forth in the applicable credit agreement), plus a spread ranging from 1.75% to 2.10% . Interest is payable monthly. Borrowings may be prepaid without penalty. In addition, the Personal Loan Warehouse Credit Facilities require payment of a monthly unused commitment fee ranging from 0.375% to 1.25% per annum on the average undrawn portion available. The Personal Loan and Auto Loan Warehouse Credit Facilities contain certain covenants. As of March 31, 2020 , the Company was in material compliance with all applicable covenants under the respective credit agreements. As of March 31, 2020 and December 31, 2019 , the Company had $390.0 million and $387.3 million in aggregate debt outstanding under the Personal Loan and Auto Loan Warehouse Credit Facilities, respectively, with collateral consisting of loans at fair value of $499.8 million and $551.5 million included in “Loans held for sale by the Company at fair value,” respectively, and restricted cash of $22.0 million and $25.1 million included in the Condensed Consolidated Balance Sheets , respectively. Revolving Credit Facility In December 2015, the Company entered into a credit and guaranty agreement and a pledge and security agreement with several lenders and a financial services company, as collateral agent, for an aggregate $120.0 million secured revolving credit facility (Revolving Facility). The Company may borrow under the Revolving Facility until December 17, 2020 . Repayment of any outstanding proceeds are payable on December 17, 2020 , and may be prepaid without penalty. Borrowings under the Revolving Facility bear interest, at the Company’s option, at an annual rate of LIBOR plus a spread of 1.75% to 2.00% , which is fixed for a Company-selected interest period of one, two, three, six or twelve months, or at an alternative base rate (which is tied to either the prime rate, federal funds effective rate plus 0.50% , or the adjusted eurocurrency rate plus 1.00% , as defined in the credit agreement) plus a spread of 0.75% to 1.00% . Base rate borrowings may be prepaid at any time without penalty, however pre-payment of LIBOR-based borrowings before the end of the selected interest period may result in the Company incurring expense to compensate the lenders for their funding costs through the end of the interest period. Interest is payable quarterly. Additionally, the Company is required to pay a quarterly commitment fee to the lenders of between 0.25% and 0.375% per annum, depending on the Company’s total net leverage ratio, on the average undrawn portion available under the Revolving Facility. The Revolving Facility contains certain covenants. As of March 31, 2020 , the Company was in material compliance with all applicable covenants in the credit and guaranty agreement. The Company had $110.0 million and $60.0 million in debt outstanding under the Revolving Facility as of March 31, 2020 and December 31, 2019 , respectively. Repurchase Agreements In 2018 and 2019, the Company entered into repurchase agreements pursuant to which the Company sold securities (subject to an obligation to repurchase such securities at a specified future date and price) in exchange for cash, primarily to finance securities retained from the Company’s Structured Program transactions. The Company is subject to margin calls based on the fair value of the securities to be repurchased. As of March 31, 2020 and December 31, 2019 , the Company had $121.0 million and $140.2 million in aggregate debt outstanding under its repurchase agreements, respectively, of which, at March 31, 2020 , $51.7 million had contractual repurchase dates ranging from May 2020 to December 2026 and $69.3 million is subject to a repurchase date in May 2020 that requires counterparty approval to extend such repurchase date. Subsequent to the end of the quarter, the repurchase agreement was converted to a daily rolling evergreen 45-day maturity structure. As of May 1, 2020, the maturity date is mid-June 2020. Margin calls based on the fair value of the securities were $10.4 million in the first quarter of 2020 . The contractual repurchase dates correspond to either a set repurchase schedule or to the maturity dates of the underlying securities, which have a remaining weighted-average estimated life from 1.3 to 1.8 years. The repurchase agreements bear interest at a rate that is based on a benchmark of the three-month LIBOR rate or the weighted-average interest rate of the securities sold plus a spread of 0.65% to 2.50% . Securities sold are included in “Credit facilities and securities sold under repurchase agreements” on the Condensed Consolidated Balance Sheets . As of March 31, 2020 and December 31, 2019 , the Company had $130.2 million and $174.8 million , respectively, of underlying assets sold under repurchase agreements. Payable to Structured Program Note and Certificate Holders In the fourth quarter of 2019 and first quarter of 2020, the Company sponsored securitization transactions through master trusts consisting of $244.4 million in unsecured personal whole loans in aggregate. The trusts sold certificate participations and securities to third-party investors in an amount equal to approximately 95% of the loans for $228.7 million in net proceeds. The remaining certificate participations, securities, and residual interests were retained by the Company. The Company is the primary beneficiary of the trusts, which are consolidated. As of March 31, 2020 and December 31, 2019 , the certificate participations and securities held by third-party investors of $206.1 million and $40.6 million are included in “Payable to Structured Program note and certificate holders at fair value” in the Condensed Consolidated Balance Sheets and were secured by loans held for investment and loans held for sale by the Company at fair value of $205.7 million and $40.3 million and restricted cash of $12.6 million and $2.9 million included in the Condensed Consolidated Balance Sheets , respectively.

Stockholders' Equity

Stockholders' Equity	3 Months Ended

Equity [Abstract]
Stockholders' Equity	Stockholders’ Equity Preferred Stock The Company authorized 10,000,000 shares of preferred stock with a par value of $0.01 per share. In February 2020, the Company filed Certificates of Designations with the Secretary of State of Delaware to designate, of the total authorized shares of preferred stock, 1,200,000 shares of Series A Preferred Stock and 600,000 shares of Series B Preferred Stock. As of March 31, 2020, there were 195,628 shares of Series A Preferred Stock outstanding and no shares of Series B Preferred Stock outstanding. Each share of Series A Preferred Stock will automatically convert into 100 shares of LendingClub common stock upon a permissible transfer to an unaffiliated third party (subject to adjustment and the other terms described in its respective Certificate of Designations), provided that upon such conversion, the holder, together with its affiliates, will not own or control, in the aggregate, more than 9.9% of the Company’s outstanding common stock. A permissible transfer is a transfer (a) to the Company; (b) in a widespread public distribution; (c) in which no one transferee (or group of associated transferees) would receive 2% or more of any class of the Company’s voting securities then outstanding (including pursuant to a related series of such transfers); or (d) to a transferee that would control more than 50% of the Company voting securities (not including voting securities such person is acquiring from the transferor). The shares of Series A Preferred Stock have no voting rights, except as otherwise required by the General Corporation Law of the State of Delaware. The Series A Preferred Stock ranks pari passu with the common stock, and junior to any other series of preferred stock that is issued by the Company with respect to rights upon liquidation, winding up and dissolution and as to rights to dividends, provided, however, that in case of a liquidation, winding up or dissolution the Series A Preferred Stock has a right to receive $0.01 per share before any payment is made to the holders of LendingClub common stock, and will thereafter participate on a pari passu basis with the common stock. The Series B Preferred Stock, if issued, will (a) be nonredeemable; (b) have a minimum preferential quarterly dividend of $0.001 per share or any higher per share dividend declared on LendingClub common stock; (c) in the event of a liquidation be entitled to receive a preferred liquidation payment equal to $0.001 per share plus the per share amount paid in respect of a share of LendingClub common stock; (d) will have one vote, voting together with LendingClub common stock; and (e) in the event of any merger, consolidation or other transaction in which shares of LendingClub common stock are exchanged, will be entitled to receive the per share amount paid in respect of each share of LendingClub common stock. The rights of holders of the Series B Preferred Stock with respect to dividends, liquidation and voting, and in the event of mergers and consolidations, are protected by customary antidilution provisions. There are no issued Series B Preferred Stock. Issuance of Series A Preferred Stock in Exchange for Common Stock In February 2020, the Company and Radius Bancorp, Inc. (Radius) entered into an Agreement and Plan of Merger (Merger Agreement), by and among the Company, a wholly owned-subsidiary of the Company, and Radius, pursuant to which the Company will acquire Radius and thereby acquire its wholly-owned subsidiary, Radius Bank (the Merger). In connection with the Merger and in order to facilitate compliance with federal banking regulations by Shanda, in February 2020, the Company also entered into a Share Exchange Agreement (the Exchange Agreement) pursuant to which Shanda exchanged all of its shares of the Company’s common stock (with voting rights), or 19,562,881 shares, for Series A Preferred Stock, or 195,628 shares, and a one-time cash payment of $50.2 million . The Exchange Agreement imposes certain restrictions and obligations on Shanda so as to ensure that its ownership of LendingClub securities and activities will not impede LendingClub’s ability to obtain the necessary bank regulatory approvals. On the date of the Exchange Agreement, the effective conversion price for the Series A Preferred Stock was less than the fair value of the common stock, resulting in a beneficial conversion feature that the Company recognized as a deemed dividend to the preferred stockholders and, accordingly, an adjustment to net loss to arrive at net loss attributable to common stockholders. As a result, the Company recorded the deemed dividend of $50.2 million within accumulated deficit for the quarter ended March 31, 2020.

Postemployment Benefits [Abstract]
Employee Incentive Plans	Employee Incentive Plans The Company’s 2014 Equity Incentive Plan (EIP) provides for granting awards, including restricted stock units (RSUs), performance-based restricted stock units (PBRSUs) and stock options to employees, officers and directors. Stock-based Compensation Stock-based compensation expense was as follows for the periods presented: Three Months Ended 2020 2019 RSUs and PBRSUs $ 17,706 $ 17,185 Stock options 423 715 ESPP — 352 Total stock-based compensation expense $ 18,129 $ 18,252 The following table presents the Company’s stock-based compensation expense recorded in the Condensed Consolidated Statements of Operations : Three Months Ended 2020 2019 Sales and marketing $ 1,663 $ 1,571 Origination and servicing 636 924 Engineering and product development 4,615 5,231 Other general and administrative 11,215 10,526 Total stock-based compensation expense $ 18,129 $ 18,252 The Company capitalized $1.6 million and $1.9 million of stock-based compensation expense associated with developing software for internal use during the first quarters of 2020 and 2019 , respectively. Restricted Stock Units The following table summarizes the activities for the Company’s RSUs during the first quarter of 2020 : Number of Units Weighted- Average Grant Date Fair Value Unvested at December 31, 2019 9,597,404 $ 16.78 Granted 8,273,646 $ 10.42 Vested (893,306 ) $ 18.89 Forfeited/expired (395,864 ) $ 15.64 Unvested at March 31, 2020 16,581,880 $ 13.52 During the first quarter of 2020 , the Company granted 8,273,646 RSUs with an aggregate fair value of $86.2 million . As of March 31, 2020 , there was $212.5 million of unrecognized compensation cost related to unvested RSUs, which is expected to be recognized over the next 3.2 years. Performance-based Restricted Stock Units PBRSUs are equity awards that are earned, and eligible for time-based vesting, based upon the achievement of certain pre-established performance metrics over a specific performance period. Depending on the level of achievement of the pre-established performance targets, the PBRSUs earned and eligible for time-based vesting can range from 0% to 200% of the target amount. PBRSUs granted under the Company’s EIP generally have a one -year performance period with the earned shares, if any, vesting over an additional approximately two -year period. Over the performance period, the number of PBRSUs that may be earned and the related stock-based compensation expense that is recognized is adjusted upward or downward based upon the probability of achieving the pre-established performance metrics. During the first quarter of 2019, the Company expanded the use of its PBRSU program to nearly all of the executive team. The following table summarizes the activities for the Company’s PBRSUs during the first quarter of 2020 : Number of Units Weighted- Average Grant Date Fair Value Unvested at December 31, 2019 471,589 $ 16.94 Vested (41,577 ) $ 21.82 Forfeited/expired (1) (183,016 ) $ 16.77 Unvested at March 31, 2020 246,996 $ 16.24 (1) Represents the portion of PBRSUs granted in 2018 and 2019 that were unearned as a result of not achieving certain pre-established performance metrics during the performance period. For the first quarters of 2020 and 2019 , the Company recognized $0.8 million and $0.9 million in stock-based compensation expense related to PBRSUs, respectively. As of March 31, 2020 , there was $1.8 million of unrecognized compensation cost related to unvested PBRSUs, which is expected to be recognized over the next 1.4 years . Employee Stock Purchase Plan In connection with the Company’s cost structure simplification efforts, future purchases through the Company’s employee stock purchase plan (ESPP) were suspended effective upon the completion of the most recent offering period on May 10, 2019.

Income Tax Disclosure [Abstract]
Income Taxes	Income Taxes For the first quarter of 2020, the Company recorded income tax expense of $319 thousand , which is primarily attributable to the tax effects of unrealized losses recorded to other comprehensive income associated with the Company’s available for sale portfolio. The Company did not record any income tax expense during the first quarter of 2019. The Company continues to recognize a full valuation allowance against net deferred tax assets. This determination was based on the assessment of the available positive and negative evidence to estimate if sufficient future taxable income will be generated to utilize the existing deferred tax assets.

Leases [Abstract]
Leases	Leases The Company has operating leases for its headquarters in San Francisco, California, as well as additional office space for its origination and servicing operations in the Salt Lake City area, Utah, and Westborough, Massachusetts. As of March 31, 2020 , the lease agreements have remaining lease terms ranging from approximately one year to nine years . Some of the lease agreements include options to extend the lease term for up to an additional fifteen years and some of them include options to terminate the lease with six months ’ prior notice. In addition, the Company is the sublessor of a portion of its office space in San Francisco, with lease terms of approximately two years .

Commitments and Contingencies Disclosure [Abstract]
Commitments and Contingencies	Commitments and Contingencies Operating Lease Commitments For discussion regarding the Company’s operating lease commitments, see “ Note 17. Leases . ” Loan Purchase Obligation Under the Company’s loan account program with WebBank, which serves as the Company’s primary issuing bank for loans facilitated through the Company’s platform, WebBank retains ownership of the loans it originates for two business days after origination. As part of this arrangement, the Company is committed to purchase any loans that have been fully approved at par plus accrued interest, at the conclusion of the two business days. As of March 31, 2020 and December 31, 2019 , the Company was committed to purchase loans with an outstanding principal balance of $13.3 million and $91.3 million at par, respectively. Loan Repurchase Obligations The Company is generally required to repurchase loans or interests therein in the event of identity theft or certain other types of fraud on the part of the borrower or education and patient service providers. The Company may also repurchase loans or interests therein in connection with certain customer accommodations. In connection with certain whole loan and Certificate Program sales, as well as to facilitate access to securitization markets, the Company has agreed to repurchase loans if representations and warranties made with respect to such loans are breached under certain circumstances. In the case of certain securitization transactions, the Company has also agreed to repurchase or substitute loans for which a borrower fails to make the first payment due under a loan. The Company believes such provisions are customary and consistent with institutional loan and securitization market standards. In addition to and distinct from the repurchase obligations described in the preceding paragraph, the Company performs certain administrative functions for a variety of retail and institutional investors, including executing, without discretion, loan investments as directed by the investor. To the extent loans do not meet the investor’s investment criteria at the time of issuance, or are transferred to the investor as a result of a system error by the Company, the Company repurchases such loans or interests therein at par. As a result of the loan repurchase obligations described above, the Company repurchased $1.1 million and $2.0 million in loans or interests therein during the first quarters of 2020 and 2019 , respectively. Purchase Commitments As required by applicable regulations, the Company must make firm offers of credit with respect to prescreened direct mail it sends out to prospective applicants provided such applicants continue to meet the credit worthiness criteria which were used to screen them at the time of their application and the application is completed prior to the offer’s stated expiration date. If such loans are accepted by the applicants but not otherwise funded by investors on the platform, the Company is required to facilitate funding for the loans directly with its issuing bank partners at minimum amounts, which are generally below the requested loan amount. The Company was not required to purchase any such loans during the first quarter of 2020 . Additionally, loans in the process of being facilitated through the Company’s platform and originated by the Company’s issuing bank partner at March 31, 2020 , were substantially funded in April 2020 . As of the date of this Report, no fully-approved loans remained without investor commitments. During the month of April 2020, the Company was required to purchase approximately $230 thousand of these loans. In addition, if neither the Company nor Springstone can arrange for other investors to invest in or purchase loans that Springstone facilitates and that are originated by an issuing bank partner but do not meet the credit criteria for purchase by the issuing bank partner, the Company and Springstone are contractually committed to purchase these loans. As of both March 31, 2020 and December 31, 2019 , the Company had a $9.0 million deposit in a bank account to secure potential future purchases of these loans, if necessary. The funds are recorded as restricted cash on the Company’s Condensed Consolidated Balance Sheets . During the first quarter of 2020 , the Company was required to purchase $13.2 million of loans facilitated by Springstone. These purchased loans are held on the Company’s Condensed Consolidated Balance Sheets and have a fair value of $44.8 million and $45.7 million as of March 31, 2020 and December 31, 2019 , respectively. The Company believes it will be required to purchase additional loans facilitated by Springstone in 2020 as it seeks to arrange for other investors to invest in or purchase these loans. Acquisition-related Commitments On February 18, 2020, the Company and Radius entered into an Agreement and Plan of Merger (as previously discussed in “ Note 14. Stockholders' Equity ”), in a cash and stock transaction valued at $185 million , subject to certain purchase price and expense adjustments of up to $22 million . The Company has entered into acquisition-related agreements, which include contingent fees of approximately $3 million as of March 31, 2020 , due upon closing of the transaction. Legal The Company is subject to various claims brought in a litigation or regulatory context. These matters include lawsuits and federal regulatory litigation, including but not limited to putative class action lawsuits, derivative lawsuits, and litigation with the FTC. In addition, the Company continues to cooperate in federal and state regulatory examinations, investigations, and actions relating to the Company’s business practices and licensing, and is a party to a number of routine litigation matters arising in the ordinary course of business. The majority of these claims and proceedings relate to or arise from alleged state or federal law and regulatory violations, or are alleged commercial disputes or consumer complaints. The Company accrues for costs related to contingencies when a loss from such claims is probable and the amount of loss can be reasonably estimated. In determining whether a loss from a claim is probable and the loss can be reasonably estimated, the Company reviews and evaluates its litigation and regulatory matters on at least a quarterly basis in light of potentially relevant factual and legal developments. If the Company determines an unfavorable outcome is not probable or the amount of loss cannot be reasonably estimated, the Company does not accrue for a potential litigation loss. In those situations, the Company discloses an estimate or range of the reasonably possible losses, if such estimates can be made. Except as otherwise specifically noted below, at this time, the Company does not believe that it is possible to estimate the reasonably possible losses or a range of reasonably possible losses related to the matters described below. Derivative Lawsuits On November 6, 2017, a putative shareholder derivative action was filed in the U.S. District Court for the Northern District of California ( Sawyer v. Sanborn, et al., No. 3:17-cv-06447) against certain of the Company’s current and former officers and directors and naming the Company as a nominal defendant. This action was based on allegations similar to those in a consolidated putative securities class action litigation ( In re LendingClub Securities Litigation , No. 16-cv-02627 (N.D. Cal.)) that was successfully settled in 2018. In July 2018, the Company and the individual defendants brought a motion to dismiss the Sawyer matter on the grounds that the action was not filed within the applicable statute of limitations. The Court granted that motion and judgment was entered in favor of the defendants. The Sawyer plaintiff also attempted to intervene in a previously filed derivative action in the U.S. District Court for the Northern District of California ( Stadnicki v. LaPlanche, et al. , No. 3:16-cv-03072). The Company and the individual defendants opposed the intervention, and the original Stadnicki plaintiff moved to voluntarily dismiss the case. The motion to intervene was denied and the motion to voluntarily dismiss the Stadnicki action was granted. Notices of appeal were filed in both the Sawyer and Stadnicki actions. The appeal in the Sawyer matter was dismissed at the Sawyer plaintiff’s request. Oral argument in the appeal in the Stadnicki matter was heard on February 3, 2020 and on February 25, 2020, the U.S. Court of Appeals for the Ninth Circuit issued a ruling affirming the trial court’s denial of the Sawyer plaintiff’s motion to intervene in the Stadnicki case. It is unclear at this time whether the Sawyer plaintiff will attempt to seek further review of the Ninth Circuit’s ruling. Accordingly, it is not possible for the Company to predict the outcome of the Stadnicki action at this time. FTC Lawsuit In 2016, the Company received a formal request for information from the Federal Trade Commission (FTC). The FTC commenced an investigation concerning certain of the Company’s policies and practices and related legal compliance. On April 25, 2018, the FTC filed a complaint in the Northern District of California ( FTC v. LendingClub Corporation , No. 3:18-cv-02454) alleging causes of action for violations of the FTC Act, including claims of deception in connection with disclosures related to the origination fee associated with loans available through the Company’s platform, and in connection with communications relating to the likelihood of loan approval during the application process, and a claim of unfairness relating to certain unauthorized charges to borrowers’ bank accounts. The FTC’s complaint also alleged a violation of the Gramm-Leach-Bliley Act regarding the Company’s practices in delivering its privacy notice. In June 2018, the Company brought a motion to dismiss the FTC’s complaint, which was heard on September 13, 2018. In an order dated October 3, 2018, the Court denied the motion in part and granted the motion in part, providing the FTC with leave to amend its pleadings. On October 22, 2018, the FTC filed an amended complaint which reasserted the same causes of action from the original complaint. On November 13, 2018, the Company filed an answer to the amended complaint. The FTC subsequently filed a motion seeking to strike certain affirmative defenses pled in the answer and the Company filed an opposition to the motion. On April 29, 2019, the Court issued a ruling denying the FTC’s motion in part and granting it in part and allowing the Company to replead certain of the affirmative defenses that were the subject of the FTC’s motion. The Company filed an amended answer in the case on May 29, 2019. The discovery period in the case is closed. On February 27, 2020, both the Company and the FTC filed various motions with the Court, including motions to exclude expert testimony and motions for summary judgment as to some or all of the claims in the case. The FTC also filed a motion for partial judgment on the pleadings in the case. These motions were heard by the Court on April 27, 2020. The Court has not yet issued a decision on the motions. The Court has issued scheduling orders that set various deadlines in the case, including a June 22, 2020 trial commencement date. The Company denies, and will continue to vigorously defend against, the claims asserted in this case. Notwithstanding the Company’s vigorous defense, the Company and the FTC have participated in voluntary settlement conferences and may engage in additional settlement discussions. No assurances can be given as to the timing, outcome or consequences of this matter. Class Action Lawsuits Following Announcement of FTC Litigation In May 2018, following the announcement of the FTC’s litigation against the Company, putative shareholder class action litigation was filed in the U.S. District Court of the Northern District of California ( Veal v. LendingClub Corporation et.al., No. 5:18-cv-02599) against the Company and certain of its current and former officers and directors alleging violations of federal securities laws in connection with the Company’s description of fees and compliance with federal privacy law in securities filings. The Court appointed lead plaintiffs and lead counsel for the litigation in November 2018. On January 7, 2019, the lead plaintiffs filed a consolidated amended class action complaint which asserts the same causes of action as the original complaint and adds additional allegations. On March 8, 2019, the Company and the individual defendants in the case filed motions to dismiss the consolidated amended class action complaint. A hearing on these motions was held on September 26, 2019. On November 4, 2019, the Court issued a written order granting defendants’ motions to dismiss with leave to amend. Plaintiff filed a Second Amended Complaint on December 19, 2019, which modifies and adds certain allegations and drops one of the former officer defendants as a defendant in the case, but otherwise advances the same causes of action. Defendants filed a motion to dismiss the Second Amended Complaint on January 28, 2020. The Court heard argument on this motion on April 30, 2020. The Court has not yet issued a decision on this motion. This lawsuit is in the early stages. The Company denies and will vigorously defend against the allegations. No assurances can be given as to the timing, outcome or consequences of this matter. In July 2019, a putative class action lawsuit was filed against the Company in federal court in the State of New York ( Shron v. LendingClub Corp. , 1:19-cv-06718) alleging various claims including fraud, unjust enrichment, breach of contract, and violations of the federal Truth-in-Lending Act and New York General Business Law sections 349 and 350, et seq., based on allegations, among others, that the Company made misleading or inadequate statements or omissions in relation to the total cost and origination fee associated with loans available through the Company’s platform. The plaintiff seeks to represent classes of similarly situated individuals in the lawsuit. The Company has filed a motion to compel arbitration of plaintiff’s claims on an individual basis. The timing of a ruling on that motion is unclear. This matter is in the early stages. The Company denies and will vigorously defend against the allegations. No assurances can be given as to the timing, outcome or consequences of this matter. Derivative Lawsuits Following FTC Litigation In July 2018, a putative shareholder derivative action was filed in the U.S. District Court for the Northern District of California ( Baron v. Sanborn, et al. No. 3:18-cv-04391) against certain of the Company’s current and former officers and directors and naming the Company as a nominal defendant. This action is based on allegations that the individuals breached their fiduciary duties to the Company and violated federal securities laws by, among other things, permitting the actions alleged in the FTC litigation and the description of fees and other practices in the Company’s securities filings. In January 2019, a second putative shareholder derivative action was filed in the U.S. District Court for the Northern District of California ( Cheekatamarla v. Sanborn, et al ., No. 3:19-cv-00563) against certain of the Company’s current officers and directors and naming the Company as a nominal defendant. Like the Baron action, this action is based on allegations that the individuals breached their fiduciary duties to the Company and violated federal securities laws by, among other things, permitting the actions alleged in the FTC litigation and the description of fees and other practices in the Company’s securities filings. Pursuant to a stipulation by the parties in both of these derivative cases, the Court consolidated the two cases and stayed the consolidated action pending further developments in Veal . In September 2019, co-lead counsel for plaintiffs in the consolidated action filed a notice and proposed order to lift the temporary stay and the Court issued an order lifting the stay. Subsequent to this order, the case was reassigned and the new Court issued an order staying the consolidated action pending resolution of the Veal action. No assurances can be given as to the timing, outcome or consequences of this consolidated matter. In August 2019, a putative shareholder derivative action was filed in the Court of Chancery for the State of Delaware ( Fisher v. Sanborn, et al. , Case No. 2019-0631) against certain of the Company’s current and former officers and directors and naming the Company as a nominal defendant. This lawsuit advances allegations similar to those in the consolidated Baron/Cheekatamarla actions and the Veal action discussed above and accuses the individual defendants of breaching their fiduciary duties by failing to adequately monitor the Company and prevent it from engaging in the purported regulatory violations alleged by the FTC and by causing the Company to make allegedly false and misleading public statements (as alleged in the Veal action). The lawsuit also alleges that certain of the individual defendants breached their fiduciary duties by selling Company shares while in possession of material, non-public information. On October 11, 2019, the Company and the individual defendants filed a motion to dismiss the complaint. In November 2019, rather than oppose defendants’ motion to dismiss, the plaintiff filed an amended complaint. That same month, the Company and the individual defendants named in the amended complaint filed a motion to dismiss that amended complaint. On January 17, 2020, rather than oppose defendants’ motion to dismiss, the plaintiff filed a second amended complaint. On January 24, 2020, defendants filed a motion to strike the second amended complaint as improper. The Court denied the defendants’ motion to strike and allowed the plaintiff to advance the second amended complaint as the operative complaint in the case. The defendants have filed a motion to dismiss the second amended complaint which is currently set to be heard by the Court on July 2, 2020. No assurances can be given as to the timing, outcome or consequences of this matter. Regulatory Investigation by the State of Massachusetts In June 2018, the Company received a civil investigative demand from the office of the Attorney General of the State of Massachusetts. The investigation related to the advertisement, provision and servicing of personal loans to Massachusetts’ consumers facilitated by the Company, including the Company’s compliance with the Massachusetts Small Loan Law and the Small Loan Rate Order promulgated under it. The Company cooperated with the investigation and finalized an Assurance of Discontinuance in January 2020 with the Attorney General’s Office to resolve the investigation, the terms of which are not material to the Company’s financial position or results of operations. In December 2019, the Massachusetts Division of Banks raised concerns pertaining to the Company’s compliance with the Massachusetts Small Loan Law similar to those the Massachusetts Attorney General’s Office raised during its investigation of the Company. No assurances can be given as to the timing, outcome or consequences of this matter; however, it could result in claims or actions against the Company, including litigation, regulatory enforcement actions, injunctions, monetary damages, fines or penalties, impact our licenses in Massachusetts, or require us to change our business practices or expend operational resources, all of which could result in a material loss or otherwise harm our business. Regulatory Examinations and Actions Relating to the Company’s Business Practices and Licensing The Company has been subject to periodic inquiries and enforcement actions brought by federal and state regulatory agencies relating to the Company’s business practices, the required licenses to operate its business, and its manner of operating in accordance with the requirements of its licenses. In the past, the Company has successfully resolved inquiries in a manner that was not material to its results of financial operations in any period and that did not materially limit the Company’s ability to conduct its business. The Company has had discussions with the Colorado Department of Law (CDL) concerning the licenses required for the Company’s servicing operations and the structure of its offerings in the State of Colorado. The Company has also had discussions with the CDL about entering into a terminable agreement with the CDL to, among other things: (i) toll the statutes of limitations on any action the CDL might bring against the Company based on the rates and charges on loans the Company facilitates and (ii) refrain from facilitating certain loans to borrowers located in Colorado available for investment by certain investors. No assurances can be given as to the timing, outcome or consequences of this matter. The Company is routinely subject to examination for compliance with applicable laws and regulations in the states in which it is licensed. As of the date of this Report, the Company is subject to examination by the New York Department of Financial Services (NYDFS) and other regulators. The Company periodically has discussions with various regulatory agencies regarding its business model and has engaged in similar discussions with the NYDFS. During the course of such discussions with the NYDFS, which remain ongoing, the Company decided to voluntarily comply with certain rules and regulations of the NYDFS. No assurances can be given as to the timing, outcome or consequences of this matter or others if or as they arise. Putative Class Actions In September 2018, a lawsuit was filed against the Company in the State of New York ( Accardo v. Lending Club, et al. , 2:18-cv-05030-JS-AKT) asserting an individual claim under the federal Fair Credit Reporting Act against the Company. In early 2019, the plaintiff filed a motion for leave to amend his complaint in the case to assert a putative class claim under the Fair Credit Reporting Act. The plaintiff’s proposed amended complaint contends that LendingClub failed to conduct a reasonable investigation into plaintiff’s identity theft dispute and plaintiff seeks to represent a class of similarly situated individuals. The Company filed an opposition to plaintiff’s motion for leave to amend and also filed a motion to compel arbitration of plaintiff’s claim against the Company on an individual basis. The Court denied the Company’s motion to compel arbitration and ordered a trial on whether an arbitration agreement exists between the Company and Plaintiff. The Court also denied without prejudice Plaintiff’s motion for leave to amend. The Company has finalized a settlement with the plaintiff to resolve this matter, the terms of which are not material to the Company’s financial position or results of operations. This matter is now concluded. In February 2020, a putative class action lawsuit was filed against the Company in the U.S District Court for the Northern District of California ( Erceg v. LendingClub Corporation , No. 3:20-cv-01153). The lawsuit alleges violations of California and Massachusetts law based on allegations that LendingClub recorded a call with plaintiff without notifying him that it would be recorded. Plaintiff seeks to represent a purported class of similarly situated individuals who had phone calls recorded by LendingClub without their knowledge and consent. LendingClub filed a motion to dismiss certain of plaintiff’s claims, strike nationwide class allegations, and, alternatively, to stay the litigation. No assurances can be given as to the timing, outcome or consequences of this matter. California Private Attorneys General Lawsuit In September 2018, a putative action under the California Private Attorney General Act was brought against the Company in the California Superior Court ( Brott v. LendingClub Corporation, et al. , CGC-18-570047) alleging violations of the California Labor Code. The complaint by a former employee alleges that the Company improperly failed to pay certain hourly employees for all wages owed, pay the correct rate of pay including overtime, and provide accurate wage statements. The lawsuit alleges that the plaintiff and aggrieved employees are entitled to recover civil penalties under the California Labor Code. On January 11, 2019, the Company filed a petition to compel arbitration of the plaintiff’s claims and stay the litigation pending a ruling on the motion and arbitration of the matter. Pursuant to the parties’ stipulation, in March 2019, the Court issued an order staying the lawsuit pending the parties’ participation in a mediation in September 2019. The parties have reached a resolution of this matter, the terms of which are not material to the Company’s financial position or results of operations. The resolution will require court approval. The parties have finalized a written settlement agreement and will seek the Court’s approval of the negotiated resolution. Certain Financial Considerations Relating to Litigation and Investigations With respect to the matters discussed above, the Company had $14.8 million and $16.0 million in accrued contingent liabilities at March 31, 2020 and December 31, 2019 , respectively. In addition to the foregoing, the Company is subject to, and may continue to be subject to, legal proceedings and regulatory actions in the ordinary course of business. No assurance can be given as to the timing, outcome or consequences of any of these matters.

Segment Reporting

Segment Reporting [Abstract]
Segment Reporting	Segment Reporting The Company defines operating segments to be components of the Company for which discrete financial information is evaluated regularly by the Company’s executive management committee as chief operating decision maker (CODM). For purposes of allocating resources and evaluating financial performance, the Company’s CODM reviews financial information by loan product types of personal, education and patient finance, and auto. These product types are individually reviewed as operating segments but are aggregated to represent one reportable segment because the education and patient finance and auto loan product types are immaterial both individually and in the aggregate. In the second quarter of 2019, the Company sold certain assets relating to its small business operating segment and announced that it will connect applicants looking for a small business loan with strategic partners and earn referral fees, instead of facilitating these loans on its platform. All of the Company’s revenue is generated in the United States. No individual borrower or investor accounted for 10% or more of consolidated net revenue for any of the periods presented.

Related Party Transactions [Abstract]
Related Party Transactions	Related Party Transactions Related party transactions must be reviewed and approved by the Audit Committee of the Company’s board of directors when not conducted in the ordinary course of business subject to the standard terms of the Company’s lending marketplace or certificate investment program. Any material amendment or modification to an existing related party transaction is also subject to the review and approval of the Audit Committee. Related party transactions may include any transaction between entities under common control or with a related person that has occurred since the beginning of the Company’s latest fiscal year or is currently proposed. The Company has defined related persons as members of the board of directors, executive officers, principal owners of the Company’s outstanding stock and any immediate family members of each such related person, as well as any other person or entity with significant influence over the Company’s management or operations. Several of the Company’s executive officers and directors (including immediate family members) have made deposits and withdrawals to their investor accounts and purchased loans or interests therein. The Company believes all such transactions by related persons were made in the ordinary course of business and were transacted on terms and conditions that were not more favorable than those obtained by similarly situated third-party investors. In February 2020, the Company entered into an exchange agreement with its largest stockholder, Shanda, pursuant to which, on March 20, 2020, Shanda exchanged all of 19,562,881 shares of LendingClub common stock held by it for (i) 195,628 newly issued shares of mandatorily convertible, non-voting, LendingClub preferred stock, series A, both with a par value of $0.01 per share, and (ii) a one-time cash payment of $50.2 million . See “ Note 14. Stockholders' Equity ,” for additional information. As of March 31, 2020 , the Company had a $7.8 million investment and an approximate 22% ownership interest in an Investment Fund, a private fund that participates in a family of funds with other unrelated third parties. This family of funds purchases whole loans and interests in loans from the Company, as well as other assets from third parties unrelated to the Company. The Company’s investment in the Investment Fund is recorded in “Other assets” on the Company’s Condensed Consolidated Balance Sheets . During the first quarter of 2019 , the family of funds purchased $77 thousand of whole loans. The family of funds did not purchase whole loans during the first quarter of 2020. During the first quarters of 2020 and 2019 , the Company earned $15 thousand and $28 thousand in investor fees from this family of funds, and paid interest of $66 thousand and $327 thousand on the funds’ interests in whole loans, respectively. The Company believes that the investor fees charged were on terms and conditions that were not more favorable than those obtained by other third-party investors. The Investment Fund provides audited financial statements annually and periodic investment statements throughout each calendar year on a delayed basis, which are used by the Company to evaluate performance and recoverability of our investment.

Subsequent Events [Abstract]
Subsequent Events	Subsequent Events The Company has evaluated the impact of events that have occurred subsequent to March 31, 2020 , through the date the condensed consolidated financial statements were filed with the SEC. Based on this evaluation, other than as recorded or disclosed within these condensed consolidated financial statements and related notes, including as disclosed below, the Company has determined no additional subsequent events were required to be recognized or disclosed. On April 20, 2020, the Company approved a restructuring plan to address the impact of COVID-19 on the Company’s business. The restructuring plan includes workforce reductions affecting approximately 460 employees, or approximately 30% of the Company’s workforce, including one named executive of the Company. The Company expects to incur total pre-tax restructuring and related charges of approximately $10 million during the remainder of 2020, of which approximately $1 million represents an employee relief plan to assist impacted employees through this challenging time and the remainder represents future cash expenditures for the payment of severance and related benefits costs, with final payment before the end of the calendar year. There is a minimal retention period, and Company expects to expense a majority of the severance and related benefit costs in the second quarter of 2020.

Summary of Significant Accoun_2

Summary of Significant Accounting Policies (Policies)	3 Months Ended
	Mar. 31, 2020
Accounting Policies [Abstract]
Securities Available for Sale	Securities Available for Sale Debt securities that the Company might not hold until maturity are classified as securities available for sale. In structured program transactions that meet the applicable criteria to be accounted for as a sale, the Company retains certain asset-backed securities including subordinated residual interests and CLUB Certificates, which are classified as securities available for sale. On January 1, 2020, the entity adopted ASU 2016-13, Financial Instruments – Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments (CECL) for securities available for sale. Asset-backed securities where the expected cash flows are significantly lower than that of the contractual future cash flows are considered to be purchased with credit deterioration (PCD). The discounted differential in expected and contractual cash flows is included with the purchase price of the asset to determine amortized cost of the security with an equal and offsetting valuation allowance for credit losses. Securities available for sale are recorded at fair value and unrealized gains and losses are reported, net of taxes, in “Accumulated other comprehensive income (loss)” included in Equity in the Company’s Consolidated Balance Sheets, unless management determines that the security is impaired due to a deterioration in expected cash flows, in which case the unrealized loss is recognized in earnings within “Net fair value adjustments” as a valuation allowance for credit losses (with the implementation of CECL) or other-than-temporary impairment (prior to the implementation of CECL) in the Company’s Condensed Consolidated Statements of Operations . Management evaluates whether debt securities available for sale with unrealized losses are impaired on a quarterly basis. If the Company intends to sell the security, or if it is more likely than not that it will be required to sell the security before recovery, an impairment is recognized in earnings equal to the entire difference between the amortized cost basis and fair value of the debt security. However, even if the Company does not expect to sell a debt security it must evaluate if a deterioration in cash flows exists.
Accrued Interest Receivable on Loans	Accrued Interest Receivable on Loans The Company does not record an allowance for credit losses on accrued interest receivable. The Company places loans on non-accrual status at 90 days past due. When a loan is placed on non-accrual status, the Company stops accruing interest and reverses all accrued but unpaid interest income as of such date.
Net Income (Loss) Per Share	Net Income (Loss) Per Share Basic net income (loss) per share (Basic EPS) attributable to common stockholders is computed by dividing net income (loss) attributable to LendingClub by the weighted-average number of common shares outstanding during the period. Diluted net income (loss) per share (Diluted EPS) is computed by dividing net income (loss) attributable to LendingClub by the weighted-average number of common shares outstanding during the period, adjusted for the effects of dilutive issuances of shares of common stock, which include incremental shares issued for outstanding RSUs, PBRSUs, and stock options. PBRSUs are included in dilutive shares to the extent the pre-established performance targets have been or are estimated to be satisfied as of the reporting date. The dilutive potential common shares are computed using the treasury stock method. The effects of outstanding RSUs, PBRSUs, and stock options are excluded from the computation of Diluted EPS in periods in which the effect would be antidilutive. For periods with more than one class of common shares, the Company computes Basic and Diluted EPS using the two-class method, which is an allocation of net income (loss) among the holders of each class of common shares. The Series A Preferred Stock is considered a separate class of common share for purposes of calculating net income (loss) per share because it participates in earnings similar to common stock and does not receive any significant preferences over the common stock.
Beneficial Conversion Feature	Beneficial Conversion Feature The Company accounts for the beneficial conversion feature (BCF) on its Series A Preferred Stock in accordance with ASC 470-20, Debt with Conversion and Other Options . The Company accretes the BCF discount from the date of issuance to the earliest conversion date, which was March 20, 2020. All of the BCF discount was accreted and recognized as a deemed dividend in “Accumulated deficit” on the Company’s Condensed Consolidated Balance Sheets. See “ Note 14. Stockholders' Equity ” for additional information.
Adoption of New Accounting Standards	Adoption of New Accounting Standards The Company adopted the following accounting standards during the three month period ended March 31, 2020 : On January 1, 2020, the entity adopted ASU 2016-13, Financial Instruments – Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments . For loans accounted for at amortized cost, the guidance replaces the incurred loss impairment methodology with an expected credit loss model for which a company recognizes an allowance based on the estimate of expected credit loss. As the Company has elected the fair value option for loans and loans accounted for at fair value through net income are outside the scope of Topic 326, there is no impact on the Company’s loan portfolios. For debt securities available for sale, Topic 326 requires recognition of expected credit losses by recognizing an allowance for credit losses when the fair value of the security is below amortized cost and the recognition of this allowance is limited to the difference between the security’s amortized cost basis and fair value. Upon adoption, the amendments in Topic 326 are recognized through a cumulative-effect adjustment to retained earnings, except for debt securities with prior other-than-temporary impairment whereby Topic 326 is applied prospectively. The Company adopted ASC 326 using the prospective transition approach for debt securities for which other-than-temporary impairment had been recognized prior to January 1, 2020. As a result, the amortized cost basis remains the same before and after the effective date of ASC 326. The effective interest rate on these debt securities was not changed. Amounts previously recognized in accumulated other comprehensive income as of January 1, 2020 relating to improvements in cashflows expected to be collected are accreted into income over the remaining life of the asset. Recoveries of amounts previously written off relating to improvements in cash flows after January 1, 2020 are recorded in earnings when received. Additionally, the Company adopted ASC 326 using the prospective transition approach for PCD financial assets. The Company did not have any previously classified assets as purchased credit impaired (PCI) under ASC 310-30. In accordance with this standard, management did not reevaluate for PCD upon transition. Adoption of Topic 326 did not have an impact on the Company’s financial position, results of operations, and cash flows. The Company did not record a cumulative effect adjustment to retained earnings. The Company included the disclosures required by ASU 2016-13 in “ Note 5. Securities Available for Sale . ” In August 2018, the FASB issued ASU 2018-13, Fair Value Measurement (Topic 820): Disclosure Framework – Changes to the Disclosure Requirements for Fair Value Measurement , which modifies the disclosure requirements on fair value measurements by removing, modifying, or adding certain disclosures. The ASU eliminates such disclosures as the amount of and reasons for transfers between Level 1 and Level 2 of the fair value hierarchy and valuation processes for Level 3 fair value measurements. The ASU adds new disclosure requirements for Level 3 measurements. The new guidance became effective on January 1, 2020 and did not have a material impact on the Company’s related disclosures. In August 2018, the FASB issued ASU 2018-15, Intangibles – Goodwill and Other – Internal-Use Software – (Subtopic 350-40): Customer’s Accounting for Implementation Costs Incurred in a Cloud Computing Arrangement That Is a Service Contract , which requires a customer in a hosting arrangement that is a service contract to follow the internal-use software guidance in ASC 350-40 to determine which implementation costs to capitalize as assets or expense as incurred. The standard became effective on January 1, 2020 and the Company adopted the standard using the prospective approach. The Company has reviewed existing cloud computing arrangements and determined which ones are service contracts. Implementation costs that are not from internal developers related to service contracts that satisfy the criteria for capitalization under ASC 350-40 will be presented with “Other assets” on the Company’s Consolidated Balance Sheets, amortization expense will be presented in the same line on the income statement as the fees for the associated hosted service on the Company’s Consolidated Statements of Operations, and the cash flows will be presented consistent with the presentation of cash flows for the fees related to the hosted service, generally as cash flows from operations, on the Company’s Consolidated Statements of Cash Flows. Adoption of the standard did not have a material impact on the Company’s financial position, results of operations, cash flows, or disclosures. New Accounting Standards Not Yet Adopted In December 2019, the FASB issued ASU 2019-12, Income Taxes (Topic 740): Simplifying the Accounting for Income Taxes , which is part of the FASB’s initiative to reduce complexity in accounting standards. The proposed ASU eliminates certain exceptions to the general principles of ASC 740, Income Taxes , and simplifies income tax accounting in several areas. The standard is effective on January 1, 2021 with early adoption permitted. The Company is evaluating the impact this ASU will have on its financial position, results of operations, cash flows, and disclosures, but does not expect such adoption to have a material impact. In March 2020, the FASB issued ASU 2020-04, Reference Rate Reform (Topic 848): Facilitation of the Effects of Reference Rate Reform on Financial Reporting, which, if certain criteria are met, provides optional expedients and exceptions for applying generally accepted accounting principles to transactions affected by reference rate reform. These transactions include contract modifications, hedging relationships, and sale or transfer of debt securities classified as held-to-maturity. The provisions of the new standard may be adopted as of the beginning of the reporting period when the election is made until December 31, 2022. The Company is evaluating the impact this ASU will have on its financial position, results of operations, cash flows, and disclosures. The Company has not elected an adoption date.
