Accounting Policies [Abstract]
General	NOTE 1. GENERAL Business . Prologis, Inc. (or the “Parent”) commenced operations as a fully integrated real estate company in 1997, elected to be taxed as a real estate investment trust (“REIT”) under the Internal Revenue Code of 1986, as amended (the “Internal Revenue Code”), and believes the current organization and method of operation will enable it to maintain its status as a REIT. The Parent is the general partner of Prologis, L.P. (or the “Operating Partnership” or “OP”). Through the OP, we are engaged in the ownership, acquisition, development and management of logistics facilities with a focus on key markets in 19 countries on four continents. We invest in real estate through wholly owned subsidiaries and other entities through which we co-invest with partners and investors. We maintain a significant level of ownership in these co-investment ventures, which may be consolidated or unconsolidated based on our level of control of the entity. Our current business strategy consists of two operating business segments: Real Estate Operations and Strategic Capital. Our Real Estate Operations segment represents the ownership and development of logistics properties. Our Strategic Capital segment represents the management of unconsolidated co-investment ventures and other ventures. See Note 12 for further discussion of our business segments. Unless otherwise indicated, the Notes to the Consolidated Financial Statements apply to both the Parent and the OP. The terms “the Company,” “Prologis,” “we,” “our” or “us” means the Parent and OP collectively For each share of preferred or common stock the Parent issues, the OP issues a corresponding preferred or common partnership unit, as applicable, to the Parent in exchange for the contribution of the proceeds from the stock issuance. At September 30, 2020, the Parent owned a 97.30% common general partnership interest in the OP and 100% of the preferred units in the OP. The remaining 2.70% common limited partnership interests, which include Class A common limited partnership units (“Class A Units”) in the OP, are owned by unaffiliated investors and certain current and former directors and officers of the Parent. Each partner’s percentage interest in the OP is determined based on the number of OP units held, including the number of OP units into which Class A Units are convertible, compared to total OP units outstanding at each period end and is used as the basis for the allocation of net income or loss to each partner. At the end of each reporting period, a capital adjustment is made in the OP to reflect the appropriate ownership interest for each of the common unitholders. These adjustments are reflected in the line items Reallocation of Equity Reallocation of Capital As the sole general partner of the OP, the Parent has complete responsibility and discretion in the day-to-day management and control of the OP and we operate the Parent and the OP as one enterprise. The management of the Parent consists of the same members as the management of the OP. These members are officers of the Parent and employees of the OP or one of its subsidiaries. As general partner with control of the OP, the Parent is the primary beneficiary and therefore consolidates the OP. Because the Parent’s only significant asset is its investment in the OP, the assets and liabilities of the Parent and the OP are the same on their respective financial statements. Basis of Presentation. The accompanying Consolidated Financial Statements are prepared in accordance with United States (“U.S.”) generally accepted accounting principles (“GAAP”) and are presented in our reporting currency, the U.S. dollar. All material intercompany transactions with consolidated entities have been eliminated. The accompanying unaudited interim financial information has been prepared according to the rules and regulations of the U.S. Securities and Exchange Commission (“SEC”). Certain information and note disclosures normally included in our annual financial statements prepared in accordance with GAAP have been condensed or omitted in accordance with such rules and regulations. Our management believes that the disclosures presented in these financial statements are adequate to make the information presented not misleading. In our opinion, all adjustments and eliminations, consisting only of normal recurring adjustments, necessary to present fairly the financial position and results of operations for both the Parent and the OP for the reported periods have been included. The results of operations for such interim periods are not necessarily indicative of the results for the full year. The accompanying unaudited interim financial information should be read in conjunction with our Annual Report on Form 10-K for the year ended December 31, 2019, as filed with the SEC, and other public information. New Accounting Pronouncements. Accounting for Lease Concessions Related to the Effects of the Coronavirus (“COVID-19”) Pandemic . In April 2020, the Financial Accounting Standards Board (“FASB”) issued a Staff Question-and-Answer (“Q&A”) to clarify whether lease concessions related to the effects of COVID-19 require the application of the lease modification guidance under the new lease standard, which we adopted on January 1, 2019. For rent deferrals granted during the nine months ended September 30, 2020, we are allowing customers to defer rental payments until a later date, generally later in 2020 or early 2021, in exchange for a note receivable, and we are continuing to recognize rental revenue during the period. In accordance with the Q&A, we are electing to not apply the lease modification guidance to concessions that result in deferred rent as the total cash flows required by the modified lease agreements are materially the same as the cash flows required under the original lease and there are no substantive changes to the consideration. As of October 19, 2020, we have granted deferral requests of $21.0 million related to consolidated properties during 2020. If we grant concessions to a customer that modify the terms and significantly change the underlying cash flows of the original lease for the remaining term, we will account for these changes as a lease modification in accordance with U.S. GAAP. Reference Rate Reform . In March 2020, the FASB issued an Accounting Standard Update (“ASU”) that provided practical expedients to address existing guidance on contract modifications and hedge accounting due to the expected market transition from the London Inter - bank Offered Rate (“LIBOR”) and other interbank offered rates (together “IBORs”) to alternative reference rates, such as the Secured Overnight Financing Rate . In July 2017, the Financial Conduct Authority announced it intended to stop compelling banks to submit rates for the calculation of LIBOR after 2021. We refer to this transition as “reference rate reform.” The first practical expedient allows companies to elect to not apply certain modification accounting requirements to debt, derivative and lease contracts affected by reference rate reform if certain criteria are met. These criteria include the following: (i) the contract referenced an IBOR rate that is expected to be discontinued; (ii) the modified terms directly replace or have the potential to replace the IBOR rate that is expected to be discontinued; and (iii) any contemporaneous changes to other terms that change or have the potential to change the amount and timing of contractual cash flows must be related to the replacement of the IBOR rate. If the contract meets all three criteria, there is no requirement for remeasurement of the contract at the modification date or reassessment of the previous accounting determination. The second practical expedient allows companies to change the reference rate and other critical terms related to the reference rate reform in derivative hedge documentation without having to dedesignate the hedging relationship. This allows for companies to continue applying hedge accounting to existing cash flow and net investment hedges. The ASU was effective upon issuance on a prospective basis beginning January 1, 2020 and may be elected over time as reference rate reform activities occur. We have not modified any contracts to date, however, we will evaluate any debt, derivative and lease contracts that are modified in the future to ensure they are eligible for modification relief and apply the practical expedients as needed.

Liberty Transaction

Liberty Transaction	9 Months Ended

Business Combinations [Abstract]
Liberty Transaction	NOTE 2. LIBERTY TRANSACTION On February 4, 2020, we acquired Liberty Property Trust and Liberty Property Limited Partnership (collectively “Liberty” or the “Liberty Transaction”). The Liberty Transaction was completed for $13.0 billion through the issuance of equity based on the value of the Prologis common stock and units issued of $10.0 billion, the assumption of debt of $2.8 billion and transaction costs. In connection with the transaction, each issued and outstanding share or unit held by a Liberty stockholder or unitholder was converted automatically into 0.675 shares of Prologis common stock or common units of Prologis, L.P., respectively, including shares and units under Liberty’s equity incentive plan that became fully vested at closing. Through the Liberty Transaction, we acquired a portfolio primarily comprised of logistics real estate assets, including 519 industrial operating properties, aggregating 99.6 million square feet, which are highly complementary to our U.S. portfolio in terms of product quality, location and growth potential in our key markets here was approximately 34 million square feet of non-strategic industrial properties acquired in the Liberty Transaction that we do not intend to operate long-term. Depending on the expected hold period, these assets are either classified as Assets Held for Sale or Contribution or other real estate investments within Investments in Real Estate Properties in the Consolidated Balance Sheets. In addition, we acquired an ownership interest in eight ventures that own industrial and office properties. The aggregate equity consideration is calculated below (in millions, except price per share): Number of Prologis shares and units issued upon conversion of Liberty shares and units at February 4, 2020 109.01 Multiplied by closing price of Prologis' common stock on February 3, 2020 $ 91.87 Fair value of Prologis shares and units issued $ 10,015 We accounted for the Liberty Transaction as an asset acquisition and as a result, the transaction costs of $115.8 million were capitalized to the basis of the acquired properties. Transaction costs included investment banker advisory fees, legal fees and other costs Under acquisition accounting, the total purchase price was allocated as follows to the Liberty real estate properties and related lease intangibles on a relative fair value basis and all other assets and liabilities assumed at fair value (in millions): Net investments in real estate $ 12,631 Intangible assets, net of intangible liabilities (1) 491 Cash and other assets 240 Debt (2,845 ) Accounts payable, accrued expenses and other liabilities (385 ) Noncontrolling interests (1 ) Total purchase price, including transaction costs $ 10,131 (1) Intangible assets of $640.5 million and intangible liabilities of $149.9 million were included within Other Assets and Other Liabilities , respectively, on the Consolidated Balance Sheets. The acquired lease intangibles from the Liberty Transaction will be amortized over the terms of the respective leases with a weighted average remaining lease term of 66 months.

Equity Method Investments And Joint Ventures [Abstract]
Unconsolidated Entities	NOTE 4. UNCONSOLIDATED ENTITIES Summary of Investments We have investments in entities through a variety of ventures. We co-invest in entities that own multiple properties with partners and investors and we provide asset and property management services to these entities, which we refer to as co-investment ventures. These entities may be consolidated or unconsolidated, depending on the structure, our partner’s participation and other rights and our level of control of the entity. This note details our investments in unconsolidated co-investment ventures, which are related parties and are accounted for using the equity method of accounting. See Note 8 for more detail regarding our consolidated investments that are not wholly owned. We also have investments in other ventures, generally with one partner and that we do not manage, which we account for using the equity method. We refer to our investments in both unconsolidated co-investment ventures and other ventures, collectively, as unconsolidated entities. The following table summarizes our investments in and advances to our unconsolidated entities (in thousands): September 30, December 31, 2020 2019 Unconsolidated co-investment ventures $ 6,393,888 $ 5,873,784 Other ventures (1) 917,072 363,587 Total $ 7,310,960 $ 6,237,371 (1) In February 2020, we completed the Liberty Transaction and acquired an equity method investment in eight ventures.

( 2 ) PBLV and our other Brazilian joint ventures are combined as one venture for the purpose of this table. (3) Prologis’ investment balance is presented at our adjusted basis derived from the ventures’ U.S. GAAP information. The difference between our ownership interest of a venture’s equity and our investment balance at September 30, 2020 and December 31, 2019, results principally from four types of transactions: (i) deferred gains from the contribution of property to a venture prior to January 1, 2018; (ii) recording additional costs associated with our investment in the venture; (iii) receivables, principally for fees and promotes ($100.2 million and $152.0 million, respectively); and (iv) customer security deposits retained subsequent to property contributions to Nippon Prologis REIT, Inc. ( 4 ) Represents our weighted average ownership interest in all unconsolidated co-investment ventures based on each entity’s contribution of total assets before depreciation, net of other liabilities. Equity Commitments Related to Certain Unconsolidated Co-Investment Ventures At September 30, 2020, our remaining equity commitments were $336.6 million, primarily for Prologis China Logistics Venture. Our equity commitments expire from 2021 to 2028.

We subsequently paid down $1.8 billion of the assumed debt with senior notes we issued at lower rates in February 2020. See below for additional activity on debt assumed in the Liberty Transaction and the extinguishment of a significant portion of the debt subsequent to acquisition. (4) Through the IPT Transaction, USLV assumed $ million of secured mortgage debt, all of which was paid down at closing. See below for the early extinguishment of debt in the IPT Transaction. Credit Facilities We have a global senior credit facility (the “Global Facility”) under which we may draw in British pounds sterling, Canadian dollars, euro, Japanese yen, Mexican pesos Pricing under the Global Facility, including the spread over LIBOR, facility fees and letter of credit fees, varies based on the public debt ratings of the OP. The Global Facility is scheduled to mature in January 2023; however, we may extend the maturity date for six months on two occasions, subject to the satisfaction of certain conditions and payment of extension fees. We have the ability to increase the Global Facility to $4.5 billion, subject to currency fluctuations and obtaining additional lender commitments. We also have a Japanese yen revolver (the “Revolver”) that we upsized in July 2020 with total commitments of ¥55.0 billion ($520.3 million at September 30, 2020). We have the ability to increase the borrowing capacity of the Revolver to ¥75.0 billion ($709.5 million at September 30, 2020), subject to obtaining additional lender commitments. Pricing under the Revolver, including the spread over Yen LIBOR, facility fees and letter of credit fees, varies based on the public debt ratings of the OP. At September 30, 2020, the Revolver was scheduled to mature in July 2024; however, we may extend the maturity date for one year, subject to the satisfaction of certain conditions and payment of extension fees. We refer to the Global Facility and the Revolver, collectively, as our “Credit Facilities.” Senior Notes The following table summarizes the issuances and redemptions of senior notes during the nine months ended September 30, 2020 (principal in thousands): Aggregate Principal Initial Borrowing Date Borrowing Currency USD (1) Weighted Average Stated Interest Rate at the Issuance Date Maturity Dates February (2)(3) € 1,350,000 $ 1,485,405 0.6% February 2022 – 2035 February (2) $ 2,200,000 $ 2,200,000 2.4% April 2027 – 2050 February £ 250,000 $ 322,490 1.9% February 2035 June (3)(4) ¥ 41,200,000 $ 386,314 1.0% June 2027 – 2050 August (3)(5) $ 1,250,000 $ 1,250,000 1.6% October 2030 – 2050 September ¥ 19,700,000 $ 186,835 1.0% September 2032 – 2040 Aggregate Principal Redemption Date Borrowing Currency USD (1) Stated Interest Rate at the Redemption Date Maturity Dates January € 400,000 $ 445,880 0.0% January 2020 March (2) € 700,000 $ 783,090 1.4% May 2021 June (4) € 212,598 $ 238,067 3.0% January 2022 June (4) € 100,486 $ 112,524 3.4% February 2024 September (5) $ 850,000 $ 850,000 4.3% August 2023 (1) The exchange rate used to calculate into U.S. dollars was the spot rate at the settlement date.

(4) We utilized the proceeds from the issuance of the Japanese yen senior notes to redeem €212.6 million ($238.1 million) and €100.5 million ($112.5 million) (5) We utilized the proceeds from this issuance to redeem $850.0 In February 2020, we completed an exchange offer for two series of Liberty’s senior notes for an aggregate amount of $750.0 million, with $689.8 million, or 92.0%, of the aggregate principal amount being validly tendered for exchange. These senior notes are in the aggregate principal amounts of $400.0 million due in October 2026 with an interest rate of 3.3% and $350.0 million due in February 2029 with an interest rate of 4.4%. The senior notes were exchanged for notes issued by a wholly owned subsidiary and guaranteed by the OP. As a result of the exchange offer, we have no separate remaining financial reporting obligations or financial covenants associated with the senior notes assumed in the Liberty Transaction. All other terms of the exchanged Liberty senior notes remained substantially the same. Term Loans During the nine months ended September 30, 2020, we extended the maturity of the multi-currency term loan (“2017 Term Loan”) by one year until May 2021. We may extend the maturity for one additional year, subject to the satisfaction of certain conditions and the payment of an extension fee.

These entities are 100% indirectly owned by the OP and all unsecured debt issued or to be issued by each entity is or will be fully and unconditionally guaranteed by the OP. There are no restrictions or limits on the OP’s ability to obtain funds from its subsidiaries by dividend or loan.

Equity [Abstract]
Stockholders' Equity of Prologis, Inc.	NOTE 7. STOCKHOLDER’S EQUITY OF PROLOGIS, INC. Share Purchase Program In March 2020, the Board of Directors authorized a new share purchase program for the repurchase of outstanding shares of our common stock on the open market or in privately negotiated transactions for an aggregate purchase price of up to $1.0 billion. In March 2020, we repurchased and retired 0.5 million shares of common stock for an aggregate price of $34.8 million at a weighted average price of $64.66 per share on the open market. Shares Authorized In April 2020, our stockholders approved an amendment to our Articles of Incorporation that increased the number of authorized shares from 1.0 billion to 2.0 billion shares of common stock. Common Stock In May 2020, we entered into a new at-the-market program that allows us to sell up to $1.5 billion in aggregate gross sales proceeds of shares of common stock through twenty designated agents. These agents earn a fee of up to 2% of the gross sales price per share of common stock as agreed to on a transaction-by-transaction basis. We have not issued any shares of common stock under this new program. Preferred Stock In August 2020, we repurchased 0.1 million shares of Series Q preferred stock and recognized a loss of $2.3 million, which primarily represented the difference between the repurchase price and the carrying value of the preferred stock, net of the original issuance costs.

Noncontrolling Interest [Abstract]
Noncontrolling Interests	NOTE 8. NONCONTROLLING INTERESTS Prologis, L.P. We report noncontrolling interests related to several entities we consolidate but of which we do not own 100% of the equity. These entities include two real estate partnerships that have issued limited partnership units to third parties. Depending on the specific partnership agreements, these limited partnership units are redeemable for cash or, at our option, into shares of the Parent’s common stock, generally at a rate of one share of common stock to one limited partnership unit. We also consolidate certain entities in which we do not own 100% of the equity, but the equity of these entities is not exchangeable into our common stock. Prologis, Inc. The noncontrolling interests of the Parent include the noncontrolling interests described above for the OP, as well as the limited partnership units in the OP that are not owned by the Parent. The outstanding limited partnership units receive quarterly cash distributions equal to the quarterly dividends paid on our common stock pursuant to the terms of the applicable partnership agreements.

Long-Term Compensation	NOTE 9. LONG-TERM COMPENSATION Equity-Based Compensation Plans and Programs 2020 Long-Term Incentive Plan In April 2020, our stockholders approved the 2020 Long-Term Incentive Plan (“2020 LTIP”), which replaced the 2012 Long-Term Incentive Plan (“2012 LTIP”). After approval of the 2020 LTIP, no further awards could be made under the 2012 LTIP and outstanding awards previously granted under the 2012 LTIP will remain outstanding in accordance with the awards’ terms. The 2020 LTIP provides for grants of awards to officers, directors, employees and consultants of the Parent or its subsidiaries. Awards can be in the form of: full value awards, stock appreciation rights, and stock options (non-qualified options and incentive stock options). Full value awards generally consist of: (i) common stock; (ii) restricted stock units (“RSUs”); (iii) OP LTIP units (“LTIP Units”) and (iv) Prologis Outperformance Plan (“POP”) OP LTIP units (“POP LTIP Units”). The equity-based compensation plans and programs under which awards can be made were not changed under the 2020 LTIP. See the discussion below regarding these programs. Awards may be made under the 2020 LTIP until it is terminated by the Board or until the ten-year anniversary of the effective date of the plan. Prologis Outperformance Plan (“POP”) We allocate participation points or a percentage of the compensation pool to participants under our POP corresponding to three-year -year compound annualized TSR for the Morgan Stanley Capital International (“MSCI”) US REIT Index for the same period plus 100 basis points. If the Outperformance Hurdle is met, a compensation pool will be formed equal to 3% of the excess value created, subject to a maximum as defined for each performance period. Generally, POP awards cannot be paid at a time when our absolute TSR is negative in accordance with the terms of POP. Therefore, if after seven years our TSR has not been positive, the awards will be forfeited. We granted participation points for the 2020 – 2022 performance period in January 2020, with a fair value of $28.8 million using a Monte Carlo valuation model that assumed a risk-free interest rate of 1.7% and an expected volatility of 16.0%. The 2020 – 2022 performance period has an absolute maximum cap of $100 million. If an award is earned at the end of the initial three-year performance period, then 20% of the POP award is paid and the remaining 80% is subject to additional seven-year three-year three-year The Outperformance Hurdle was met for the 2017 – 2019 performance period, which resulted in awards being earned at December 31, 2019. Initial awards of $75.0 million in aggregate were awarded in January 2020 in the form of 0.3 million shares of common stock and 0.5 million POP LTIP Units and LTIP Units. Participants are not able to sell or transfer equity awards received until three years after the end of the initial period. One-third of the remaining compensation pool in excess of the $75 million aggregate initial award amounts can be earned at the end of each of the three years following the end of the initial three-year three-year Other Equity-Based Compensation Plans and Programs Our other equity-based compensation plans and programs include (i) the Prologis Promote Plan (“PPP”); (ii) the annual long-term incentive (“LTI”) equity award program (“Annual LTI Award”); and (iii) the annual bonus exchange program. Awards under these plans and programs may be issued in the form of RSUs of the Parent or LTIP Units of the OP at the eligible participant’s election. RSUs and LTIP Units are valued based on the market price of the Parent’s common stock on the date the award is granted and the grant date value is charged to compensation expense over the service period. Summary of Award Activity RSUs The following table summarizes the activity for RSUs for the nine months ended September 30, 2020 (units in thousands): Weighted Average Unvested RSUs Grant Date Fair Value Balance at January 1, 2020 1,165 $ 68.44 Granted 482 94.76 Vested and distributed (510 ) 62.99 Forfeited (63 ) 77.80 Balance at September 30, 2020 1,074 $ 80.52 LTIP Units The following table summarizes the activity for LTIP Units for the nine months ended September 30, 2020 (units in thousands): Vested Unvested Unvested Weighted Average LTIP Units LTIP Units Grant Date Fair Value Balance at January 1, 2020 3,714 2,678 $ 60.06 Granted - 1,087 96.59 Vested LTIP Units 976 (976 ) 63.47 Vested POP LTIP Units (1) 303 - N/A Unvested POP LTIP Units (1) - 345 19.03 Conversion to common limited partnership units (1,110 ) - N/A Balance at September 30, 2020 3,883 3,134 $ 67.09 (1) Vested and unvested units were based on the POP performance criteria being met for the 2017 – 2019 performance period and represented the earned award amounts.

Fair Value Measurements There have been no significant changes in our policy from what was disclosed in our Annual Report on Form 10-K for the year ended December 31, 2019. Fair Value Measurements on a Recurring Basis At September 30, 2020 and December 31, 2019, other than the derivatives discussed previously, we did not have any significant financial assets or financial liabilities that were measured at fair value on a recurring basis in the Consolidated Financial Statements. All of our derivatives held at September 30, 2020 and December 31, 2019, were classified as Level 2 of the fair value hierarchy. Fair Value Measurements on Nonrecurring Basis Acquired properties and assets we expect to sell or contribute are significant nonfinancial assets that met the criteria to be measured at fair value on a nonrecurring basis. At September 30, 2020 and December 31, 2019, we estimated the fair value of our properties using Level 2 or Level 3 inputs from the fair value hierarchy. See more information on our acquired properties in Notes 2 and 3 and assets held for sale or contribution in Note 5. Fair Value of Financial Instruments At September 30, 2020 and December 31, 2019, the carrying amounts of certain financial instruments, including cash and cash equivalents, accounts and notes receivable, accounts payable and accrued expenses were representative of their fair values. The differences in the fair value of our debt from the carrying value in the table below were the result of differences in interest rates or borrowing spreads that were available to us at September 30, 2020 and December 31, 2019, as compared with those in effect when the debt was issued or assumed, including low borrowing spreads due to our credit ratings. The senior notes and many of the issuances of secured mortgage debt contain prepayment penalties or yield maintenance provisions that could make the cost of refinancing the debt at lower rates exceed the benefit that would be derived from doing so. The following table reflects the carrying amounts and estimated fair values of our debt (in thousands): September 30, 2020 December 31, 2019 Carrying Value Fair Value Carrying Value Fair Value Credit Facilities $ 39,733 $ 39,733 $ 184,255 $ 184,255 Senior notes 14,108,021 15,053,871 9,660,570 10,228,715 Term loans and unsecured other 1,723,473 1,744,580 1,441,882 1,463,841 Secured mortgage 646,899 687,135 619,170 651,047 Total $ 16,518,126 $ 17,525,319 $ 11,905,877 $ 12,527,858 The fair value of the senior notes increased during the nine months ended September 30, 2020 due to the decrease in bond yields in the market as compared to the higher weighted average interest rates on our senior notes.

Segment Reporting [Abstract]
Business Segments	NOTE 12. BUSINESS SEGMENTS Our current business strategy includes two operating segments: Real Estate Operations and Strategic Capital. We generate revenues, earnings, net operating income and cash flows through our segments, as follows: • Real Estate Operations. This operating segment represents the ownership and development of operating properties and is the largest component of our revenue and earnings. We collect rent from our customers through operating leases, including reimbursements for the majority of our property operating costs. Each operating property is considered to be an individual operating segment with similar economic characteristics; these properties are combined within the reportable business segment based on geographic location. Our Real Estate Operations segment also includes development activities that lead to rental operations, including land held for development and properties currently under development. Within this line of business, we utilize the following: (i) our land bank; (ii) the development expertise of our local teams; and (iii) our customer relationships. Land we own and lease to customers under ground leases, along with land and buildings we lease, is also included in this segment. • Strategic Capital. This operating segment represents the management of unconsolidated co-investment ventures. We generate strategic capital revenues primarily from our unconsolidated co-investment ventures through asset management and property management services and we earn additional revenues by providing leasing, acquisition, construction, development, financing, legal and disposition services. Depending on the structure of the venture and the returns provided to our partners, we also earn revenues through promotes periodically during the life of a venture or upon liquidation. Each unconsolidated co-investment venture we manage is considered to be an individual operating segment with similar economic characteristics; these ventures are combined within the reportable business segment based on geographic location.

Supplemental Cash Flow Elements [Abstract]
Supplemental Cash Flow Information	NOTE 13. SUPPLEMENTAL CASH FLOW INFORMATION Our significant noncash investing and financing activities for the nine months ended September 30, 2020 and 2019 included the following: • We completed the Liberty Transaction on February 4, 2020 for $13.0 billion through the issuance of equity and the assumption of debt. See Note 2 for more information on this transaction. Additionally, our two U.S. co-investment ventures, USLF and USLV completed the IPT Transaction on January 8, 2020 for $2.0 billion each in a cash transaction, including the assumption and repayment of debt. See Note 6 for more information on the assumption of debt. • W e recognized Lease Right-of-Use Assets and Lease Liabilities on the Consolidated Balance Sheets, including any new leases, renewals and modifications after January 1, 2020 of $6.6 million each, and $483.9 million and $475.1 million, respectively, after January 1, 2019, related to leases in which we are the lessee.

Accounting Policies [Abstract]
Business	Business . Prologis, Inc. (or the “Parent”) commenced operations as a fully integrated real estate company in 1997, elected to be taxed as a real estate investment trust (“REIT”) under the Internal Revenue Code of 1986, as amended (the “Internal Revenue Code”), and believes the current organization and method of operation will enable it to maintain its status as a REIT. The Parent is the general partner of Prologis, L.P. (or the “Operating Partnership” or “OP”). Through the OP, we are engaged in the ownership, acquisition, development and management of logistics facilities with a focus on key markets in 19 countries on four continents. We invest in real estate through wholly owned subsidiaries and other entities through which we co-invest with partners and investors. We maintain a significant level of ownership in these co-investment ventures, which may be consolidated or unconsolidated based on our level of control of the entity. Our current business strategy consists of two operating business segments: Real Estate Operations and Strategic Capital. Our Real Estate Operations segment represents the ownership and development of logistics properties. Our Strategic Capital segment represents the management of unconsolidated co-investment ventures and other ventures. See Note 12 for further discussion of our business segments. Unless otherwise indicated, the Notes to the Consolidated Financial Statements apply to both the Parent and the OP. The terms “the Company,” “Prologis,” “we,” “our” or “us” means the Parent and OP collectively For each share of preferred or common stock the Parent issues, the OP issues a corresponding preferred or common partnership unit, as applicable, to the Parent in exchange for the contribution of the proceeds from the stock issuance. At September 30, 2020, the Parent owned a 97.30% common general partnership interest in the OP and 100% of the preferred units in the OP. The remaining 2.70% common limited partnership interests, which include Class A common limited partnership units (“Class A Units”) in the OP, are owned by unaffiliated investors and certain current and former directors and officers of the Parent. Each partner’s percentage interest in the OP is determined based on the number of OP units held, including the number of OP units into which Class A Units are convertible, compared to total OP units outstanding at each period end and is used as the basis for the allocation of net income or loss to each partner. At the end of each reporting period, a capital adjustment is made in the OP to reflect the appropriate ownership interest for each of the common unitholders. These adjustments are reflected in the line items Reallocation of Equity Reallocation of Capital As the sole general partner of the OP, the Parent has complete responsibility and discretion in the day-to-day management and control of the OP and we operate the Parent and the OP as one enterprise. The management of the Parent consists of the same members as the management of the OP. These members are officers of the Parent and employees of the OP or one of its subsidiaries. As general partner with control of the OP, the Parent is the primary beneficiary and therefore consolidates the OP. Because the Parent’s only significant asset is its investment in the OP, the assets and liabilities of the Parent and the OP are the same on their respective financial statements.
Basis of Presentation	Basis of Presentation. The accompanying Consolidated Financial Statements are prepared in accordance with United States (“U.S.”) generally accepted accounting principles (“GAAP”) and are presented in our reporting currency, the U.S. dollar. All material intercompany transactions with consolidated entities have been eliminated. The accompanying unaudited interim financial information has been prepared according to the rules and regulations of the U.S. Securities and Exchange Commission (“SEC”). Certain information and note disclosures normally included in our annual financial statements prepared in accordance with GAAP have been condensed or omitted in accordance with such rules and regulations. Our management believes that the disclosures presented in these financial statements are adequate to make the information presented not misleading. In our opinion, all adjustments and eliminations, consisting only of normal recurring adjustments, necessary to present fairly the financial position and results of operations for both the Parent and the OP for the reported periods have been included. The results of operations for such interim periods are not necessarily indicative of the results for the full year. The accompanying unaudited interim financial information should be read in conjunction with our Annual Report on Form 10-K for the year ended December 31, 2019, as filed with the SEC, and other public information.
New Accounting Pronouncements	New Accounting Pronouncements. Accounting for Lease Concessions Related to the Effects of the Coronavirus (“COVID-19”) Pandemic . In April 2020, the Financial Accounting Standards Board (“FASB”) issued a Staff Question-and-Answer (“Q&A”) to clarify whether lease concessions related to the effects of COVID-19 require the application of the lease modification guidance under the new lease standard, which we adopted on January 1, 2019. For rent deferrals granted during the nine months ended September 30, 2020, we are allowing customers to defer rental payments until a later date, generally later in 2020 or early 2021, in exchange for a note receivable, and we are continuing to recognize rental revenue during the period. In accordance with the Q&A, we are electing to not apply the lease modification guidance to concessions that result in deferred rent as the total cash flows required by the modified lease agreements are materially the same as the cash flows required under the original lease and there are no substantive changes to the consideration. As of October 19, 2020, we have granted deferral requests of $21.0 million related to consolidated properties during 2020. If we grant concessions to a customer that modify the terms and significantly change the underlying cash flows of the original lease for the remaining term, we will account for these changes as a lease modification in accordance with U.S. GAAP. Reference Rate Reform . In March 2020, the FASB issued an Accounting Standard Update (“ASU”) that provided practical expedients to address existing guidance on contract modifications and hedge accounting due to the expected market transition from the London Inter - bank Offered Rate (“LIBOR”) and other interbank offered rates (together “IBORs”) to alternative reference rates, such as the Secured Overnight Financing Rate . In July 2017, the Financial Conduct Authority announced it intended to stop compelling banks to submit rates for the calculation of LIBOR after 2021. We refer to this transition as “reference rate reform.” The first practical expedient allows companies to elect to not apply certain modification accounting requirements to debt, derivative and lease contracts affected by reference rate reform if certain criteria are met. These criteria include the following: (i) the contract referenced an IBOR rate that is expected to be discontinued; (ii) the modified terms directly replace or have the potential to replace the IBOR rate that is expected to be discontinued; and (iii) any contemporaneous changes to other terms that change or have the potential to change the amount and timing of contractual cash flows must be related to the replacement of the IBOR rate. If the contract meets all three criteria, there is no requirement for remeasurement of the contract at the modification date or reassessment of the previous accounting determination. The second practical expedient allows companies to change the reference rate and other critical terms related to the reference rate reform in derivative hedge documentation without having to dedesignate the hedging relationship. This allows for companies to continue applying hedge accounting to existing cash flow and net investment hedges. The ASU was effective upon issuance on a prospective basis beginning January 1, 2020 and may be elected over time as reference rate reform activities occur. We have not modified any contracts to date, however, we will evaluate any debt, derivative and lease contracts that are modified in the future to ensure they are eligible for modification relief and apply the practical expedients as needed.

The difference between our ownership interest of a venture’s equity and our investment balance at September 30, 2020 and December 31, 2019, results principally from four types of transactions: (i) deferred gains from the contribution of property to a venture prior to January 1, 2018; (ii) recording additional costs associated with our investment in the venture; (iii) receivables, principally for fees and promotes ($100.2 million and $152.0 million, respectively); and (iv) customer security deposits retained subsequent to property contributions to Nippon Prologis REIT, Inc. ( 4 ) Represents our weighted average ownership interest in all unconsolidated co-investment ventures based on each entity’s contribution of total assets before depreciation, net of other liabilities.

[1]	Prologis’ investment balance is presented at our adjusted basis derived from the ventures’ U.S. GAAP information. The difference between our ownership interest of a venture’s equity and our investment balance at September 30, 2020 and December 31, 2019, results principally from four types of transactions: (i) deferred gains from the contribution of property to a venture prior to January 1, 2018; (ii) recording additional costs associated with our investment in the venture; (iii) receivables, principally for fees and promotes ($100.2 million and $152.0 million, respectively); and (iv) customer security deposits retained subsequent to property contributions to Nippon Prologis REIT, Inc.
[2]	In January 2020, USLF acquired a portfolio of 108 operating properties, aggregating 18.3 million square feet, in the IPT Transaction for cash consideration of $2.0 billion, including transaction costs and the assumption and repayment of debt.
[3]	PBLV and our other Brazilian joint ventures are combined as one venture for the purpose of this table.
[4]	Represents our weighted average ownership interest in all unconsolidated co-investment ventures based on each entity’s contribution of total assets before depreciation, net of other liabilities.
