Summary of Significant Accounti

Summary of Significant Accounting Policies	9 Months Ended
	Oct. 31, 2018
Organization, Consolidation and Presentation of Financial Statements [Abstract]
Basis of presentation	Accounting Policies Basis of Presentation The Condensed Consolidated Financial Statements of Walmart Inc. and its subsidiaries ("Walmart" or the "Company") and the accompanying notes included in this Quarterly Report on Form 10-Q are unaudited. In the opinion of management, all adjustments necessary for the fair presentation of the Condensed Consolidated Financial Statements have been included. Such adjustments are of a normal, recurring nature. The Condensed Consolidated Financial Statements, and the accompanying notes, are prepared in accordance with generally accepted accounting principles in the United States ("GAAP") and do not contain certain information included in the Company's Annual Report on Form 10-K for the fiscal year ended January 31, 2018 ("fiscal 2018"). Therefore, the interim Condensed Consolidated Financial Statements should be read in conjunction with that Annual Report on Form 10-K . The Company's Condensed Consolidated Financial Statements are based on a fiscal year ending January 31 for the United States ("U.S.") and Canadian operations. The Company consolidates all other operations generally using a one-month lag and based on a calendar year. There were no intervening events during the month of October related to the operations consolidated using a lag that materially affected the Condensed Consolidated Financial Statements. The Company's business is seasonal to a certain extent due to calendar events and national and religious holidays, as well as weather patterns. Historically, the Company's highest sales volume and operating income have occurred in the fiscal quarter ending January 31. Inventories At October 31, 2018 and January 31, 2018 , the Company's inventories valued at LIFO approximated those inventories as if they were valued at FIFO. Fair Value Measurement In January 2016, the Financial Accounting Standards Board ("FASB") issued Accounting Standards Update ("ASU") 2016-01, Financial Instruments–Overall ( Topic 825) , which updates certain aspects of recognition, measurement, presentation and disclosure of financial instruments ("ASU 2016-01"). The Company adopted this ASU on February 1, 2018, which primarily impacted the Company's accounting for its investment in JD.com ("JD") and resulted in a positive adjustment to retained earnings of approximately $2.6 billion , net of tax, based on the market value of the Company's investment in JD at January 31, 2018. The adoption requires changes in fair value of the Company's investment in JD to be recorded in the Condensed Consolidated Statement of Income. The Company records and discloses certain financial and non-financial assets and liabilities at fair value. The fair value of an asset is the price at which the asset could be sold in an orderly transaction between unrelated, knowledgeable and willing parties able to engage in the transaction. The fair value of a liability is the amount that would be paid to transfer the liability to a new obligor in a transaction between such parties, not the amount that would be paid to settle the liability with the creditor. Refer to Note 5 for additional fair value disclosures. Revenue Recognition In May 2014, the FASB issued ASU 2014-09, Revenue from Contracts with Customers (Topic 606). This ASU is a comprehensive new revenue recognition model that requires a company to recognize revenue to depict the transfer of goods or services to a customer at an amount that reflects the consideration it expects to receive in exchange for those goods or services. The Company adopted the ASU on February 1, 2018, using the modified retrospective approach and applied the ASU only to contracts not completed as of February 1, 2018. Updated accounting policies and other disclosures are below. Note 11 provides the related disaggregated revenue disclosures. The impact of adopting the ASU was not material to the Condensed Consolidated Financial Statements. Sales The Company recognizes sales revenue, net of sales taxes and estimated sales returns, at the time it sells merchandise to the customer. eCommerce sales include shipping revenue and are recorded upon delivery to the customer. Additionally, estimated sales returns are calculated based on expected returns. Membership Fee Revenue The Company recognizes membership fee revenue both in the U.S. and internationally over the term of the membership, which is typically 12 months. Membership fee revenue is included in membership and other income in the Company's Condensed Consolidated Statements of Income. The deferred membership fee is included in accrued liabilities in the Company's Condensed Consolidated Balance Sheets. Gift Cards Customer purchases of gift cards, to be utilized at the Company's stores or eCommerce websites, are not recognized as sales until the card is redeemed and the customer purchases merchandise using the gift card. Gift cards in the U.S. and some countries do not carry an expiration date; therefore, customers and members can redeem their gift cards for merchandise and services indefinitely. Gift cards in some countries where the Company does business have expiration dates. While gift cards are generally redeemed within 12 months, a certain number of gift cards, both with and without expiration dates, will not be fully redeemed. Management estimates unredeemed balances and recognizes revenue for these amounts in membership and other income in the Company's Condensed Consolidated Statements of Income over the expected redemption period. Management periodically reviews and updates its estimates. Financial and Other Services The Company recognizes revenue from service transactions at the time the service is performed. Generally, revenue from services is classified as a component of net sales in the Company's Condensed Consolidated Statements of Income. Contract Balances Contract balances as a result of transactions with customers primarily consist of receivables included in receivables, net, and deferred gift card revenue included in accrued liabilities in the Company's Condensed Consolidated Balance Sheets. The following table provides the Company's receivables and deferred gift card revenue from transactions with customers: (Amounts in millions) As of October 31, 2018 Assets: Receivables from transactions with customers, net $ 1,949 Liabilities: Deferred gift card revenue $ 1,968 The deferred gift card revenue liability was $2.0 billion at January 31, 2018. Income Taxes In December 2017, the Securities and Exchange Commission staff issued Staff Accounting Bulletin No. 118, Income Tax Accounting Implications of the Tax Cuts and Jobs Act ("SAB 118"), in response to the Tax Cuts and Jobs Act of 2017 ("Tax Act"). The Company recorded a provisional benefit, as allowed by SAB 118, of $207 million during fiscal 2018 and an additional provisional benefit of $47 million and $66 million during the three and nine months ended October 31, 2018 , respectively. The adjustments to the provisional amounts are related to refinements of the transition tax for changes in assumptions and to the remeasurement of deferred taxes. The Tax Act created a new requirement that certain income (i.e., global intangible low-taxed income or "GILTI") earned by controlled foreign corporations ("CFCs") must be included currently in the gross income of the CFCs’ U.S. shareholder. Due to the complexity of the new GILTI tax rules, the Company is not yet able to reasonably estimate the long-term effects of this provision. Therefore, the Company has not yet recorded any potential deferred tax effects related to GILTI in the Condensed Consolidated Financial Statements and has not made a policy decision regarding whether to record deferred taxes on GILTI or use the period cost method. The Company has, however, included an estimate of the current GILTI impact in the annual effective tax rate for fiscal 2019. The Company has previously asserted all its unremitted earnings offshore were permanently reinvested. In the second quarter of fiscal 2019, the Company changed its repatriation assertion for certain historical and fiscal 2019 earnings. The Company plans to repatriate approximately $5 billion of cash at a cost of approximately $80 million . The tax cost of repatriating historical earnings was recorded as a discrete tax charge in second quarter of fiscal 2019, while the tax cost of repatriating current year earnings was included in the annualized effective tax rate. The Company is continuing its analysis and awaits anticipated technical guidance surrounding any potential repatriation plans beyond fiscal 2019. Final determination and disclosure will be made as more information is received, including guidance from the IRS and Treasury. In addition to the GILTI and repatriation evaluations, management is also still evaluating the Tax Act with respect to the deferred tax remeasurement, transition tax and certain policy elections. The ultimate impacts of the Tax Act may differ from provisional amounts due to additional information being accumulated to more precisely compute the amount of tax, changes in interpretations and assumptions, and additional regulatory guidance that may be issued. The Company expects to continue to revise the provisional amounts during the allowable measurement period of one year from the enactment as the Company refines its analysis of the new rules and as new guidance is issued. In February 2018, the FASB issued Accounting Standards Update ASU 2018-02, Income Statement–Reporting Comprehensive Income (Topic 220): Reclassification of Certain Tax Effects from Accumulated Other Comprehensive Income ("ASU 2018-02"). The ASU provides that the stranded tax effects from the Tax Act in accumulated other comprehensive loss may be reclassified to retained earnings. The Company adopted this ASU on February 1, 2018, which resulted in an immaterial adjustment to retained earnings. The Company's U.S. statutory tax rate is 21% . The Company's effective income tax rate was 29.5% and 41.9% for the three and nine months ended October 31, 2018 , respectively. For the nine months ended October 31, 2018, the loss related to the sale of a majority stake in the Company's retail operations in Brazil ("Walmart Brazil") increased the effective tax rate 17% , as it provided minimal realizable tax benefit. Restricted Cash In November 2016, the FASB issued ASU 2016-18, Statement of Cash Flows–Restricted Cash (Topic 230) , which requires restricted cash to be included with cash and cash equivalents when reconciling the beginning and ending amounts on the statement of cash flows. The Company adopted this ASU on February 1, 2018. Restricted cash held outside of cash and cash equivalents is primarily recorded in other-long term assets in the Condensed Consolidated Balance Sheets and was $30 million as of October 31, 2018 and was approximately $0.3 billion as of January 31, 2018 and October 31, 2017 . Recent Accounting Pronouncements In February 2016, the FASB issued ASU 2016-02, Leases (Topic 842) , which requires lease assets and liabilities to be recorded on the balance sheet. Certain qualitative and quantitative disclosures are also required. The Company will adopt this ASU and related amendments on February 1, 2019 and expects to elect certain practical expedients permitted under the transition guidance. Additionally, the Company will elect the optional transition method that allows for a cumulative-effect adjustment in the period of adoption and will not restate prior periods. Management is implementing new lease systems in connection with the adoption of this ASU; however, these systems are still being developed to comply with the new ASU and, as a result, the Company has implemented a temporary solution for initial adoption and until these systems are fully implemented. Although management continues to evaluate the effect to the Company's Condensed Consolidated Financial Statements and disclosures, management currently estimates total assets and liabilities will increase approximately $14.5 billion to $16.5 billion upon adoption, before considering deferred taxes. This estimate could change as the Company continues to progress with implementation and will also fluctuate based on the lease portfolio, discount rates and currency exchange rates as of the adoption date. Management does not expect a material impact to the Company’s Condensed Consolidated Statements of Income or Cash Flows. In June 2016, the FASB issued ASU 2016-13, Financial Instruments–Credit Losses (Topic 326) , which modifies the measurement of expected credit losses of certain financial instruments. The Company will adopt this ASU on February 1, 2020. Management is currently evaluating this ASU to determine its impact to the Company's Condensed Consolidated Financial Statements and disclosures.

Fair Value Measurements

Fair Value Measurements	9 Months Ended

Fair Value Disclosures [Abstract]
Fair value measurements	Fair Value Measurements Assets and liabilities recorded at fair value are measured using the fair value hierarchy, which prioritizes the inputs used in measuring fair value. The levels of the fair value hierarchy are: • Level 1: observable inputs such as quoted prices in active markets; • Level 2: inputs other than quoted prices in active markets that are either directly or indirectly observable; and • Level 3: unobservable inputs for which little or no market data exists, therefore requiring the Company to develop its own assumptions. The Company has equity investments, primarily its investment in JD, measured at fair value on a recurring basis included in other long-term assets in the accompanying Condensed Consolidated Balance Sheet. Beginning in fiscal 2019 due to the adoption of the new financial instrument standard, changes in fair value are recorded in other gains and losses in the Condensed Consolidated Statements of Income. Additional detail about the Company's two portions of the investment in JD are as follows: • The purchased portion of the investment in JD measured using Level 1 inputs, which prior to fiscal 2019 was classified as available-for-sale with changes in fair value recognized through other comprehensive income; and • The portion of the investment in JD received in exchange for selling certain assets related to Yihaodian, the Company's former eCommerce operations in China, measured using Level 2 inputs. Fair value is determined primarily using quoted prices in active markets for similar assets. Prior to fiscal 2019, the investment was carried at cost. Information for the cost basis, carrying value and fair value of the Company's investment in JD is as follows: (Amounts in millions) Cost Basis Carrying Value as of January 31, 2018 Fair Value as of February 1, 2018 Fair Value as of October 31, 2018 Investment in JD measured using Level 1 inputs $ 1,901 $ 3,547 $ 3,547 (1) $ 1,694 Investment in JD measured using Level 2 inputs 1,490 1,490 3,559 (2) 1,696 Total $ 3,391 $ 5,037 $ 7,106 $ 3,390 (3) (1) Fair value was already recognized on the balance sheet. Upon adoption of the new financial instrument standard on February 1, 2018, the excess of fair value over cost was reclassified from accumulated other comprehensive loss to retained earnings. (2) Upon adoption of the new financial instrument standard on February 1, 2018, the excess of fair value over cost was recognized by increasing the carrying value of the asset and retained earnings. (3) The decreases in fair value for the three and nine months ended October 31, 2018 of $1.8 billion and $ 3.7 billion , respectively, were recognized in net income and included in other gains and losses in the Company's Condensed Consolidated Statements of Income. The Company also holds derivative instruments. Derivative fair values are the estimated amounts the Company would receive or pay upon termination of the related derivative agreements as of the reporting dates. The fair values have been measured using the income approach and Level 2 inputs, which include the relevant interest rate and foreign currency forward curves. As of October 31, 2018 and January 31, 2018 , the notional amounts and fair values of these derivatives were as follows: October 31, 2018 January 31, 2018 (Amounts in millions) Notional Amount Fair Value Notional Amount Fair Value Receive fixed-rate, pay variable-rate interest rate swaps designated as fair value hedges $ 4,000 $ (160 ) $ 4,000 $ (91 ) Receive fixed-rate, pay fixed-rate cross-currency swaps designated as net investment hedges 2,250 353 2,250 208 Receive fixed-rate, pay fixed-rate cross-currency swaps designated as cash flow hedges 4,105 (237 ) 4,523 205 Total $ 10,355 $ (44 ) $ 10,773 $ 322 Nonrecurring Fair Value Measurements In addition to assets and liabilities that are recorded at fair value on a recurring basis, the Company's assets and liabilities are also subject to nonrecurring fair value measurements. Generally, fair value measurements on a nonrecurring basis are required as a result of impairment charges or business acquisitions. As discussed in Note 10 , the Company met the criteria to recognize Walmart Brazil as held for sale in the second quarter of fiscal 2019. Prior to meeting the held for sale criteria, the carrying values of the long-lived assets were concluded to be recoverable based upon cash flows expected to be generated over the assets' useful lives. When the sale of a majority stake in Walmart Brazil became probable, the Company reclassified the related assets and liabilities to held for sale and measured the disposal group at fair value, less costs to sell. As of the date of reclassification, the assets of the disposal group totaled $3.3 billion and were comprised of $1.0 billion in current assets, $1.6 billion in property and equipment and property under capital lease and financing obligations, net, and $0.7 billion of other long-term assets. These assets were fully impaired as the carrying value of the disposal group exceeded the fair value, less costs to sell. The Company recorded a pre-tax net loss of approximately $4.8 billion during the nine months ended October 31, 2018, in other gains and losses in the Company's Condensed Consolidated Statement of Income. In the third quarter of fiscal 2019, the sale was completed as discussed in Note 10 . Other impairment charges to assets measured at fair value on a nonrecurring basis during the nine months ended October 31, 2018 were immaterial. For the fiscal year ended January 31, 2018 , the Company recorded impairment charges related to assets measured at fair value on a non-recurring basis of approximately $1.4 billion primarily related to the following: • in the Sam's Club segment, $0.6 billion for restructuring charges for the Sam's Club closures for underperforming stores; the impaired assets consisted primarily of buildings and related store fixtures, and leased assets of its retail operations; • in the Walmart International segment, $0.2 billion for restructuring charges for the wind-down of the Brazil first-party eCommerce business; the impaired assets consisted primarily of fixtures and equipment; and • immaterial discontinued real estate projects in the Walmart U.S. and Sam's Club segments and decisions to exit certain international properties in the Walmart International segment. Other Fair Value Disclosures The Company records cash and cash equivalents, restricted cash, and short-term borrowings at cost. The carrying values of these instruments approximate their fair value due to their short-term maturities. The Company's long-term debt is also recorded at cost. The fair value is estimated using Level 2 inputs based on the Company's current incremental borrowing rate for similar types of borrowing arrangements. The carrying value and fair value of the Company's long-term debt as of October 31, 2018 and January 31, 2018 , are as follows: October 31, 2018 January 31, 2018 (Amounts in millions) Carrying Value Fair Value Carrying Value Fair Value Long-term debt, including amounts due within one year $ 45,866 $ 48,505 $ 33,783 $ 38,766

Derivative Financial Instrument

Derivative Financial Instruments	9 Months Ended

Summary of Derivative Instruments [Abstract]
Derivative financial instruments	Derivative Financial Instruments The Company uses derivative financial instruments for hedging and non-trading purposes to manage its exposure to changes in interest and currency exchange rates, as well as to maintain an appropriate mix of fixed- and variable-rate debt. Use of derivative financial instruments in hedging programs subjects the Company to certain risks, such as market and credit risks. Market risk represents the possibility that the value of the derivative financial instrument will change. In a hedging relationship, the change in the value of the derivative financial instrument is offset to a great extent by the change in the value of the underlying hedged item. Credit risk related to a derivative financial instrument represents the possibility that the counterparty will not fulfill the terms of the contract. The notional, or contractual, amount of the Company's derivative financial instruments is used to measure interest to be paid or received and does not represent the Company's exposure due to credit risk. Credit risk is monitored through established approval procedures, including setting concentration limits by counterparty, reviewing credit ratings and requiring collateral (generally cash) from the counterparty when appropriate. The Company only enters into derivative transactions with counterparties rated "A-" or better by nationally recognized credit rating agencies. Subsequent to entering into derivative transactions, the Company regularly monitors the credit ratings of its counterparties. In connection with various derivative agreements, including master netting arrangements, the Company held cash collateral from counterparties of $202 million and $279 million at October 31, 2018 and January 31, 2018 , respectively. The Company records cash collateral received as amounts due to the counterparties exclusive of any derivative asset. Furthermore, as part of the master netting arrangements with each of these counterparties, the Company is also required to post collateral with a counterparty if the Company's net derivative liability position exceeds $150 million with such counterparties. The Company did not have any cash collateral posted with counterparties at October 31, 2018 or January 31, 2018 . The Company records cash collateral it posts with counterparties as amounts receivable from those counterparties exclusive of any derivative liability. The contractual terms of the Company's hedged instruments closely mirror those of the hedged items, providing a high degree of risk reduction and correlation. Contracts that are effective at meeting the risk reduction and correlation criteria are recorded using hedge accounting. If a derivative financial instrument is recorded using hedge accounting, depending on the nature of the hedge, changes in the fair value of the instrument will either be offset against the change in fair value of the hedged assets, liabilities or firm commitments through earnings or be recognized in accumulated other comprehensive loss until the hedged item is recognized in earnings. Any hedge ineffectiveness is immediately recognized in earnings. The Company's net investment and cash flow instruments are highly effective hedges and the ineffective portion has not been, and is not expected to be, significant. Instruments that do not meet the criteria for hedge accounting, or contracts for which the Company has not elected hedge accounting, are recorded at fair value with unrealized gains or losses reported in earnings during the period of the change. Fair Value Instruments The Company is a party to receive fixed-rate, pay variable-rate interest rate swaps that the Company uses to hedge the fair value of fixed-rate debt. The notional amounts are used to measure interest to be paid or received and do not represent the Company's exposure due to credit loss. The Company's interest rate swaps that receive fixed-interest rate payments and pay variable-interest rate payments are designated as fair value hedges. As the specific terms and notional amounts of the derivative instruments match those of the fixed-rate debt being hedged, the derivative instruments are assumed to be perfectly effective hedges. Changes in the fair values of these derivative instruments are recorded in earnings, but are offset by corresponding changes in the fair values of the hedged items, also recorded in earnings, and, accordingly, do not impact the Company's Condensed Consolidated Statements of Income. These fair value instruments will mature on dates ranging from October 2020 to April 2024 . Net Investment Instruments The Company is a party to cross-currency interest rate swaps that the Company uses to hedge its net investments. The agreements are contracts to exchange fixed-rate payments in one currency for fixed-rate payments in another currency. All changes in the fair value of these instruments are recorded in accumulated other comprehensive loss, offsetting the currency translation adjustment of the related investment that is also recorded in accumulated other comprehensive loss. These instruments will mature on dates ranging from July 2020 to February 2030 . The Company has issued foreign-currency-denominated long-term debt as hedges of net investments of certain of its foreign operations. These foreign-currency-denominated long-term debt issuances are designated and qualify as nonderivative hedging instruments. Accordingly, the foreign currency translation of these debt instruments is recorded in accumulated other comprehensive loss, offsetting the foreign currency translation adjustment of the related net investments that is also recorded in accumulated other comprehensive loss. At October 31, 2018 and January 31, 2018 , the Company had ¥180 billion of outstanding long-term debt designated as a hedge of its net investment in Japan, as well as outstanding long-term debt of £1.7 billion at October 31, 2018 and January 31, 2018 , that was designated as a hedge of its net investment in the United Kingdom. These nonderivative net investment hedges will mature on dates ranging from July 2020 to January 2039 . Cash Flow Instruments The Company is a party to receive fixed-rate, pay fixed-rate cross-currency interest rate swaps to hedge the currency exposure associated with the forecasted payments of principal and interest of certain non-U.S. denominated debt. The swaps are designated as cash flow hedges of the currency risk related to payments on the non-U.S. denominated debt. The effective portion of changes in the fair value of derivatives designated as cash flow hedges of foreign exchange risk is recorded in accumulated other comprehensive loss and is subsequently reclassified into earnings in the period that the hedged forecasted transaction affects earnings. The hedged items are recognized foreign currency-denominated liabilities that are re-measured at spot exchange rates each period, and the assessment of effectiveness (and measurement of any ineffectiveness) is based on total changes in the related derivative's cash flows. As a result, the amount reclassified into earnings each period includes an amount that offsets the related transaction gain or loss arising from that re-measurement and the adjustment to earnings for the period's allocable portion of the initial spot-forward difference associated with the hedging instrument. These cash flow instruments will mature on dates ranging from April 2022 to March 2034 . Financial Statement Presentation Although subject to master netting arrangements, the Company does not offset derivative assets and derivative liabilities in its Condensed Consolidated Balance Sheets. Derivative instruments with an unrealized gain are recorded in the Company's Condensed Consolidated Balance Sheets as either current or non-current assets, based on maturity date, and derivative instruments with an unrealized loss are recorded as either current or non-current liabilities, based on maturity date. Refer to Note 5 for the net presentation of the Company's derivative instruments. The Company's derivative instruments, as well as its nonderivative debt instruments designated and qualifying as net investment hedges, were classified as follows in the Company's Condensed Consolidated Balance Sheets: October 31, 2018 January 31, 2018 (Amounts in millions) Fair Value Net Investment Cash Flow Fair Value Net Investment Instruments Cash Flow Derivative instruments Derivative assets: Other long-term assets $ — $ 353 $ 73 $ — $ 208 $ 300 Derivative liabilities: Deferred income taxes and other 160 — 310 91 — 95 Nonderivative hedging instruments Long-term debt — 3,735 — — 4,041 — Gains and losses related to the Company's derivatives primarily relate to interest rate hedges, which are recorded in interest, net, in the Company's Condensed Consolidated Statements of Income. Amounts related to the Company's derivatives expected to be reclassified from accumulated other comprehensive loss to net income during the next 12 months are not significant.

Class of Stock Disclosures [Abstract]
Share repurchases	Share Repurchases From time to time, the Company repurchases shares of its common stock under share repurchase programs authorized by the Company's Board of Directors. All repurchases made during the three and nine months ended October 31, 2018, were made under the plan in effect at the beginning of the fiscal year. The current $20 billion share repurchase program approved in October 2017 has no expiration date or other restrictions limiting the period over which the Company can make share repurchases. As of October 31, 2018 , authorization for $14.6 billion of share repurchases remained under the current share repurchase program. Any repurchased shares are constructively retired and returned to an unissued status. The Company considers several factors in determining when to execute share repurchases, including, among other things, current cash needs, capacity for leverage, cost of borrowings and the market price of its common stock. The following table provides, on a settlement date basis, the number of shares repurchased, average price paid per share and total amount paid for share repurchases for the nine months ended October 31, 2018 and 2017 : Nine Months Ended October 31, (Amounts in millions, except per share data) 2018 2017 Total number of shares repurchased 45.3 87.8 Average price paid per share $ 92.01 $ 75.76 Total amount paid for share repurchases $ 4,161 $ 6,656

Commitments and Contingencies Disclosure [Abstract]
Contingencies	Contingencies Legal Proceedings The Company is involved in a number of legal proceedings. The Company has made accruals with respect to these matters, where appropriate, which are reflected in the Company's Condensed Consolidated Financial Statements. For some matters, a liability is not probable or the amount cannot be reasonably estimated and therefore an accrual has not been made. However, where a liability is reasonably possible and may be material, such matters have been disclosed. The Company may enter into discussions regarding settlement of these matters, and may enter into settlement agreements, if it believes settlement is in the best interest of the Company and its shareholders. Unless stated otherwise, the matters discussed below, if decided adversely to or settled by the Company, individually or in the aggregate, may result in a liability material to the Company's financial condition or results of operations. ASDA Equal Value Claims ASDA Stores Ltd. ("Asda"), a wholly-owned subsidiary of the Company, is a defendant in over 26,000 equal value ("Equal Value") claims that began in 2008 and are proceeding before an Employment Tribunal in Manchester (the "Employment Tribunal") in the United Kingdom ("UK") on behalf of current and former Asda store employees, and further claims may be asserted in the future. The claimants allege that the work performed by female employees in Asda's retail stores is of equal value in terms of, among other things, the demands of their jobs compared to that of male employees working in Asda's warehouse and distribution facilities, and that the disparity in pay between these different job positions is not objectively justified. As a result, claimants are requesting differential back pay based on higher wage rates in the warehouse and distribution facilities and higher wage rates on a prospective basis. On March 23, 2015, Asda asked the Employment Tribunal to stay all proceedings and to "strike out" substantially all of the claims because the claimants had not adhered to the Tribunal's procedural rule for including multiple claimants on the same claim form. On July 23, 2015, the Employment Tribunal denied Asda's requests. Following additional proceedings, on June 20, 2017, the Employment Appeal Tribunal ruled in favor of Asda on the "strike out" issue and remitted the matter to the Employment Tribunal to determine whether the improperly filed claims should be struck out. On July 12, 2017, claimants sought permission from the Court of Appeals to appeal this ruling, which was granted on October 3, 2017. A hearing before the Court of Appeals on the "strike out" issue was held on October 23, 2018 and the parties are awaiting a decision. As to the initial phase of the Equal Value claims, on October 14, 2016, following a preliminary hearing, the Employment Tribunal ruled that claimants could compare their positions in Asda's retail stores with those of employees in Asda's warehouse and distribution facilities. On August 31, 2017, the Employment Appeal Tribunal affirmed the Employment Tribunal's ruling and also granted permission for Asda to appeal substantially all of its findings. Asda sought permission to appeal the remainder of the Employment Appeal Tribunal's findings to the Court of Appeals on September 21, 2017. A hearing before the Court of Appeals on the comparability findings was held on October 10, 2018 and the parties are awaiting a decision. Claimants are now proceeding in the next phase of their claims. That phase will determine whether the work performed by the claimants is of equal value to the work performed by employees in Asda's warehouse and distribution facilities. At present, the Company cannot predict the number of such claims that may be filed, and cannot reasonably estimate any loss or range of loss that may arise from these proceedings. The Company believes it has substantial factual and legal defenses to these claims, and intends to defend the claims vigorously. National Prescription Opiate Litigation and Related Matters In December 2017, the United States Judicial Panel on Multidistrict Litigation ordered numerous lawsuits filed against a wide array of defendants by various plaintiffs be consolidated, including counties, cities, healthcare providers, Native American tribes, and third-party payors, asserting claims generally concerning the impacts of widespread opioid abuse. The consolidated multidistrict litigation is entitled In re National Prescription Opiate Litigation (MDL No. 2804) , and is pending in the U.S. District Court for the Northern District of Ohio. The Company is named as a defendant in some of the cases included in this multidistrict litigation. Similar cases that name the Company have been filed in state courts by various counties and municipalities; by health care providers; and by various Native American Tribes. The relief sought by various plaintiffs is compensatory and punitive damages, as well as injunctive relief including abatement. The Company cannot predict the number of such claims that may be filed, and cannot reasonably estimate any loss or range of loss that may arise from such claims. The Company believes it has substantial factual and legal defenses to these claims, and intends to defend the claims vigorously. The Company has also been responding to subpoenas, information requests and investigations from governmental entities related to nationwide controlled substance dispensing practices involving the sale of opioids. The Company can provide no assurance as to the scope and outcome of these matters and no assurance as to whether its business, financial position, results of operations or cash flows will not be materially adversely affected. FCPA Investigation and Related Matters The Audit Committee (the "Audit Committee") of the Board of Directors of the Company has been conducting an internal investigation into, among other things, alleged violations of the U.S. Foreign Corrupt Practices Act ("FCPA") and other alleged crimes or misconduct in connection with foreign subsidiaries, including Wal-Mart de México, S.A.B. de C.V. ("Walmex"), and whether prior allegations of such violations and/or misconduct were appropriately handled by the Company. The Audit Committee and the Company have engaged outside counsel from a number of law firms and other advisors who are assisting in the on-going investigation of these matters. The Company has also been conducting a voluntary global review of its policies, practices and internal controls for anti-corruption compliance. The Company is engaged in strengthening its global anti-corruption compliance program through appropriate remedial anti-corruption measures. In November 2011, the Company voluntarily disclosed that investigative activity to the U.S. Department of Justice (the "DOJ") and the Securities and Exchange Commission (the "SEC"). Since the implementation of the global review and the enhanced anti-corruption compliance program, the Audit Committee and the Company have identified or been made aware of additional allegations regarding potential violations of the FCPA. When such allegations have been reported or identified, the Audit Committee and the Company, together with their third party advisors, have conducted inquiries and when warranted based on those inquiries, opened investigations. Inquiries or investigations regarding allegations of potential FCPA violations were commenced in a number of foreign markets where the Company operates or has operated, including, but not limited to, Brazil, China and India. As previously disclosed, the Company is under investigation by the DOJ and the SEC regarding possible violations of the FCPA. The Company has been cooperating with the agencies and discussions have been ongoing regarding the resolution of these matters. These discussions have progressed to a point that, in fiscal 2018, the Company reasonably estimated a probable loss and recorded an aggregate accrual of $283 million with respect to these matters (the "Accrual"). As the discussions are continuing, there can be no assurance as to the timing or the terms of the final resolution of these matters. A number of federal and local government agencies in Mexico carried out investigations of these matters. Walmex cooperated with the Mexican governmental agencies conducting these investigations. Furthermore, lawsuits relating to the matters under investigation were filed by several of the Company's shareholders against it, certain of its current directors, and certain of its former directors, certain of its former officers and certain of Walmex's former officers. Some of these matters have been resolved or immaterial accruals have been made for proposed settlements. The Company could be exposed to a variety of negative consequences as a result of the matters noted above. There could be one or more enforcement actions in respect of the matters that are the subject of some or all of the on-going government investigations, and such actions, if brought, may result in judgments, settlements, fines, penalties, injunctions, cease and desist orders, debarment or other relief, criminal convictions and/or penalties and the shareholder lawsuits referenced above may result in judgments against the Company and its current and former directors and officers named in those proceedings. The Company expects that there will be on-going media and governmental interest, including additional news articles from media publications on these matters, which could impact the perception among certain audiences of the Company's role as a corporate citizen. In addition, the Company has incurred and expects to continue to incur costs in responding to requests for information or subpoenas seeking documents, testimony and other information in connection with the government investigations, in defending the shareholder lawsuits, and in conducting the review and investigations. These costs will be expensed as incurred. For the three and nine months ended October 31, 2018 and 2017 , the Company incurred the following third-party expenses in connection with the FCPA investigation and related matters: Three Months Ended October 31, Nine Months Ended October 31, (Amounts in millions) 2018 2017 2018 2017 Ongoing inquiries and investigations $ 6 $ 2 $ 14 $ 22 Global compliance program and organizational enhancements 3 3 10 11 Total $ 9 $ 5 $ 24 $ 33 The Company does not presently believe that these matters, including the Accrual (and the payment of the Accrual at some point-in-time in the future), will have a material adverse effect on its business, financial position, results of operations or cash flows , although given the inherent uncertainties in such situations, the Company can provide no assurance that these matters will not be material to its business, financial position, results of operations or cash flows in the future.

Business Combinations [Abstract]
Acquisitions, disposals and related items	Acquisitions, Disposals and Related Items The following significant transactions impact, or are expected to impact, the operations of the Company's Walmart International segment. Other immaterial transactions have also occurred or been announced. Walmart Brazil In June 2018, the Company agreed to sell an 80 percent stake of Walmart Brazil to Advent International ("Advent"), and in August 2018 the sale was completed. Under the terms, Advent will contribute additional capital to the business over a three-year period and Walmart agreed to indemnify Advent for certain matters. Additionally, the Company may receive up to $250 million in contingent consideration. In the second quarter of fiscal 2019, the disposal group was classified as held for sale, which consisted of the following: • Assets of $3.3 billion , which were fully impaired as discussed in Note 5 upon meeting the held for sale criteria in the second quarter of fiscal 2019; • Liabilities of $1.3 billion , consisting of $0.7 billion in accounts payable and accrued liabilities, $0.1 billion of capital lease and financing obligations, and $0.5 billion of deferred taxes and other long-term liabilities; and • Cumulative foreign currency translation loss of $2.0 billion , which was reclassified from accumulated other comprehensive loss in the third quarter of fiscal 2019 upon closure of the sale (see Note 3 ). As a result, the Company recorded a pre-tax net loss of approximately $4.8 billion during the nine months ended October 31, 2018, in other gains and losses in the Company's Condensed Consolidated Statement of Income. Substantially all of this charge was recorded during the second quarter of fiscal 2019 upon meeting the held for sale criteria, and an additional immaterial amount was recorded during the third quarter of fiscal 2019 upon closure of the sale. In calculating the loss, the fair value of the disposal group was reduced by $0.8 billion related to an indemnity, for which a liability was recognized upon closing and is included in deferred income taxes and other in the Company's Condensed Consolidated Balance Sheet. Under the indemnity, the Company will indemnify Advent for certain pre-closing tax and legal contingencies and other matters for up to R$2.3 billion , adjusted for interest based on the Brazilian interbank deposit rate. The Company deconsolidated the financial statements of Walmart Brazil during the third quarter of fiscal 2019 and began accounting for its remaining 20 percent ownership interest, determined to have no initial fair value, using the equity method of accounting. Flipkart In August 2018, the Company acquired approximately 77 percent of the diluted shares of Flipkart Private Limited ("Flipkart"), an Indian-based eCommerce marketplace , for cash consideration of approximately $16 billion . The acquisition increases the Company's investment in India, a large, growing economy. The preliminary purchase price allocation currently consists of the following: • Assets of $24.7 billion , which comprise primarily of $2.9 billion in cash and cash equivalents, $2.3 billion in other current assets, $5.4 billion in intangible assets and $13.7 billion in goodwill. Of the intangible assets, $4.9 billion represents the fair value of trade names, each with an indefinite life, which were estimated using the income approach based on Level 3 unobservable inputs. The remaining $0.5 billion of intangible assets primarily relate to acquired technology with a life of three years. The goodwill arising from the acquisition consists largely of anticipated synergies and economies of scale primarily related to procurement and logistics and is not expected to be deductible for tax purposes; • Liabilities of $3.8 billion , which comprise of $1.9 billion of current liabilities and $1.9 billion of deferred income taxes; and • Noncontrolling interest of $4.9 billion , for which the fair value was estimated using the income approach based on Level 3 unobservable inputs. The Company began consolidating the financial statements of Flipkart in the third quarter of fiscal 2019, using a one-month lag . To finance the acquisition, the Company used a combination of cash provided by long-term debt as discussed in Note 4 and cash on hand. The Flipkart results of operations since acquisition and the pro forma financial information are immaterial. Asda In April 2018, the Company entered into a definitive agreement and announced the proposed combination of J Sainsbury plc and Asda Group Limited ("Asda Group"), the Company's wholly owned UK retail subsidiary. Under the terms of the combination, the Company would receive approximately 42 percent of the share capital of the combined company. In addition, the Company would receive approximately £3 billion in cash, subject to customary closing adjustments, and retain obligations under the Asda Group defined benefit pension plan . Due to a complex regulatory review process, the outcome of which is uncertain and may take some time to complete, the held for sale classification criteria for the disposal group has not been met as of October 31, 2018. Upon the transaction closing, the Company would deconsolidate the financial statements of Asda Group and account for the ongoing investment in the combined company using the equity method of accounting. Suburbia In April 2017, the Company sold Suburbia, the apparel retail division in Mexico, for $1.0 billion . As part of the sales agreement, the Company is also leasing certain real estate to the purchaser. The sale resulted in a pre-tax gain of $0.7 billion , of which $0.4 billion was recognized in the second quarter of fiscal 2018 in membership and other income, and the remainder was deferred and is being recognized over the lease terms of approximately 20 years .

Segment Reporting Information, Profit (Loss) [Abstract]
Segments	Segments and Disaggregated Revenue Segments The Company is engaged in the operation of retail, wholesale and other units, as well as eCommerce websites, located throughout the U.S., Africa, Argentina, Canada, Central America, Chile, China, India, Japan, Mexico, and the United Kingdom, as well as Brazil until the sale of a majority stake discussed in Note 10 . The Company's operations are conducted in three reportable segments: Walmart U.S., Walmart International and Sam's Club. The Company defines its segments as those operations whose results the chief operating decision maker ("CODM") regularly reviews to analyze performance and allocate resources. The Company sells similar individual products and services in each of its segments. It is impractical to segregate and identify revenues for each of these individual products and services entity-wide. The Walmart U.S. segment includes the Company's mass merchant concept in the U.S., as well as eCommerce. The Walmart International segment consists of the Company's operations outside of the U.S., as well as eCommerce. The Sam's Club segment includes the warehouse membership clubs in the U.S., as well as eCommerce. Corporate and support consists of corporate overhead and other items not allocated to any of the Company's segments. The Company measures the results of its segments using, among other measures, each segment's net sales and operating income, which includes certain corporate overhead allocations. From time to time, the Company revises the measurement of each segment's operating income, including any corporate overhead allocations, as determined by the information regularly reviewed by its CODM. In fiscal 2019, the Company revised certain of its corporate overhead allocations to the operating segments and, accordingly, revised prior period amounts for comparability . Net sales by segment are as follows: Three Months Ended October 31, Nine Months Ended October 31, (Amounts in millions) 2018 2017 2018 2017 Net sales: Walmart U.S. $ 80,583 $ 77,724 $ 241,146 $ 231,898 Walmart International 28,793 29,548 88,507 84,976 Sam's Club 14,521 14,864 42,933 43,737 Net sales $ 123,897 $ 122,136 $ 372,586 $ 360,611 Operating income by segment, as well as operating loss for corporate and support, interest, net, loss on extinguishment of debt and other gains and losses are as follows: Three Months Ended October 31, Nine Months Ended October 31, (Amounts in millions) 2018 2017 2018 2017 Operating income (loss): Walmart U.S. $ 3,937 $ 3,825 $ 12,343 $ 12,294 Walmart International 1,179 1,224 3,713 3,931 Sam's Club 379 433 1,106 1,223 Corporate and support (509 ) (718 ) (1,272 ) (1,478 ) Operating income 4,986 4,764 15,890 15,970 Interest, net 534 541 1,524 1,679 Loss on extinguishment of debt — 1,344 — 2,132 Other (gains) and losses 1,876 — 8,570 — Income before income taxes $ 2,576 $ 2,879 $ 5,796 $ 12,159 Disaggregated Revenues In the following tables, segment net sales are disaggregated by either merchandise category or market.

Accounting Policies Summary of

Accounting Policies Summary of Significant Accounting Policies (Policies)	9 Months Ended
	Oct. 31, 2018
Organization, Consolidation and Presentation of Financial Statements [Abstract]
Basis of Presentation and Significant Accounting Policies [Text Block]	Basis of Presentation The Condensed Consolidated Financial Statements of Walmart Inc. and its subsidiaries ("Walmart" or the "Company") and the accompanying notes included in this Quarterly Report on Form 10-Q are unaudited. In the opinion of management, all adjustments necessary for the fair presentation of the Condensed Consolidated Financial Statements have been included. Such adjustments are of a normal, recurring nature. The Condensed Consolidated Financial Statements, and the accompanying notes, are prepared in accordance with generally accepted accounting principles in the United States ("GAAP") and do not contain certain information included in the Company's Annual Report on Form 10-K for the fiscal year ended January 31, 2018 ("fiscal 2018"). Therefore, the interim Condensed Consolidated Financial Statements should be read in conjunction with that Annual Report on Form 10-K . The Company's Condensed Consolidated Financial Statements are based on a fiscal year ending January 31 for the United States ("U.S.") and Canadian operations. The Company consolidates all other operations generally using a one-month lag and based on a calendar year. There were no intervening events during the month of October related to the operations consolidated using a lag that materially affected the Condensed Consolidated Financial Statements. The Company's business is seasonal to a certain extent due to calendar events and national and religious holidays, as well as weather patterns. Historically, the Company's highest sales volume and operating income have occurred in the fiscal quarter ending January 31.
Fair Value Measurement, Policy [Policy Text Block]	Fair Value Measurement In January 2016, the Financial Accounting Standards Board ("FASB") issued Accounting Standards Update ("ASU") 2016-01, Financial Instruments–Overall ( Topic 825) , which updates certain aspects of recognition, measurement, presentation and disclosure of financial instruments ("ASU 2016-01"). The Company adopted this ASU on February 1, 2018, which primarily impacted the Company's accounting for its investment in JD.com ("JD") and resulted in a positive adjustment to retained earnings of approximately $2.6 billion , net of tax, based on the market value of the Company's investment in JD at January 31, 2018. The adoption requires changes in fair value of the Company's investment in JD to be recorded in the Condensed Consolidated Statement of Income. The Company records and discloses certain financial and non-financial assets and liabilities at fair value. The fair value of an asset is the price at which the asset could be sold in an orderly transaction between unrelated, knowledgeable and willing parties able to engage in the transaction. The fair value of a liability is the amount that would be paid to transfer the liability to a new obligor in a transaction between such parties, not the amount that would be paid to settle the liability with the creditor. Refer to Note 5 for additional fair value disclosures.
Revenue Recognition, Policy [Policy Text Block]	Revenue Recognition In May 2014, the FASB issued ASU 2014-09, Revenue from Contracts with Customers (Topic 606). This ASU is a comprehensive new revenue recognition model that requires a company to recognize revenue to depict the transfer of goods or services to a customer at an amount that reflects the consideration it expects to receive in exchange for those goods or services. The Company adopted the ASU on February 1, 2018, using the modified retrospective approach and applied the ASU only to contracts not completed as of February 1, 2018. Updated accounting policies and other disclosures are below. Note 11 provides the related disaggregated revenue disclosures. The impact of adopting the ASU was not material to the Condensed Consolidated Financial Statements. Sales The Company recognizes sales revenue, net of sales taxes and estimated sales returns, at the time it sells merchandise to the customer. eCommerce sales include shipping revenue and are recorded upon delivery to the customer. Additionally, estimated sales returns are calculated based on expected returns. Membership Fee Revenue The Company recognizes membership fee revenue both in the U.S. and internationally over the term of the membership, which is typically 12 months. Membership fee revenue is included in membership and other income in the Company's Condensed Consolidated Statements of Income. The deferred membership fee is included in accrued liabilities in the Company's Condensed Consolidated Balance Sheets. Gift Cards Customer purchases of gift cards, to be utilized at the Company's stores or eCommerce websites, are not recognized as sales until the card is redeemed and the customer purchases merchandise using the gift card. Gift cards in the U.S. and some countries do not carry an expiration date; therefore, customers and members can redeem their gift cards for merchandise and services indefinitely. Gift cards in some countries where the Company does business have expiration dates. While gift cards are generally redeemed within 12 months, a certain number of gift cards, both with and without expiration dates, will not be fully redeemed. Management estimates unredeemed balances and recognizes revenue for these amounts in membership and other income in the Company's Condensed Consolidated Statements of Income over the expected redemption period. Management periodically reviews and updates its estimates. Financial and Other Services The Company recognizes revenue from service transactions at the time the service is performed. Generally, revenue from services is classified as a component of net sales in the Company's Condensed Consolidated Statements of Income.
New accounting pronouncements, policy	Income Taxes In December 2017, the Securities and Exchange Commission staff issued Staff Accounting Bulletin No. 118, Income Tax Accounting Implications of the Tax Cuts and Jobs Act ("SAB 118"), in response to the Tax Cuts and Jobs Act of 2017 ("Tax Act"). The Company recorded a provisional benefit, as allowed by SAB 118, of $207 million during fiscal 2018 and an additional provisional benefit of $47 million and $66 million during the three and nine months ended October 31, 2018 , respectively. The adjustments to the provisional amounts are related to refinements of the transition tax for changes in assumptions and to the remeasurement of deferred taxes. The Tax Act created a new requirement that certain income (i.e., global intangible low-taxed income or "GILTI") earned by controlled foreign corporations ("CFCs") must be included currently in the gross income of the CFCs’ U.S. shareholder. Due to the complexity of the new GILTI tax rules, the Company is not yet able to reasonably estimate the long-term effects of this provision. Therefore, the Company has not yet recorded any potential deferred tax effects related to GILTI in the Condensed Consolidated Financial Statements and has not made a policy decision regarding whether to record deferred taxes on GILTI or use the period cost method. The Company has, however, included an estimate of the current GILTI impact in the annual effective tax rate for fiscal 2019. The Company has previously asserted all its unremitted earnings offshore were permanently reinvested. In the second quarter of fiscal 2019, the Company changed its repatriation assertion for certain historical and fiscal 2019 earnings. The Company plans to repatriate approximately $5 billion of cash at a cost of approximately $80 million . The tax cost of repatriating historical earnings was recorded as a discrete tax charge in second quarter of fiscal 2019, while the tax cost of repatriating current year earnings was included in the annualized effective tax rate. The Company is continuing its analysis and awaits anticipated technical guidance surrounding any potential repatriation plans beyond fiscal 2019. Final determination and disclosure will be made as more information is received, including guidance from the IRS and Treasury. In addition to the GILTI and repatriation evaluations, management is also still evaluating the Tax Act with respect to the deferred tax remeasurement, transition tax and certain policy elections. The ultimate impacts of the Tax Act may differ from provisional amounts due to additional information being accumulated to more precisely compute the amount of tax, changes in interpretations and assumptions, and additional regulatory guidance that may be issued. The Company expects to continue to revise the provisional amounts during the allowable measurement period of one year from the enactment as the Company refines its analysis of the new rules and as new guidance is issued. In February 2018, the FASB issued Accounting Standards Update ASU 2018-02, Income Statement–Reporting Comprehensive Income (Topic 220): Reclassification of Certain Tax Effects from Accumulated Other Comprehensive Income ("ASU 2018-02"). The ASU provides that the stranded tax effects from the Tax Act in accumulated other comprehensive loss may be reclassified to retained earnings. The Company adopted this ASU on February 1, 2018, which resulted in an immaterial adjustment to retained earnings. The Company's U.S. statutory tax rate is 21% . The Company's effective income tax rate was 29.5% and 41.9% for the three and nine months ended October 31, 2018 , respectively. For the nine months ended October 31, 2018, the loss related to the sale of a majority stake in the Company's retail operations in Brazil ("Walmart Brazil") increased the effective tax rate 17% , as it provided minimal realizable tax benefit. Restricted Cash In November 2016, the FASB issued ASU 2016-18, Statement of Cash Flows–Restricted Cash (Topic 230) , which requires restricted cash to be included with cash and cash equivalents when reconciling the beginning and ending amounts on the statement of cash flows. The Company adopted this ASU on February 1, 2018. Restricted cash held outside of cash and cash equivalents is primarily recorded in other-long term assets in the Condensed Consolidated Balance Sheets and was $30 million as of October 31, 2018 and was approximately $0.3 billion as of January 31, 2018 and October 31, 2017 . Recent Accounting Pronouncements In February 2016, the FASB issued ASU 2016-02, Leases (Topic 842) , which requires lease assets and liabilities to be recorded on the balance sheet. Certain qualitative and quantitative disclosures are also required. The Company will adopt this ASU and related amendments on February 1, 2019 and expects to elect certain practical expedients permitted under the transition guidance. Additionally, the Company will elect the optional transition method that allows for a cumulative-effect adjustment in the period of adoption and will not restate prior periods. Management is implementing new lease systems in connection with the adoption of this ASU; however, these systems are still being developed to comply with the new ASU and, as a result, the Company has implemented a temporary solution for initial adoption and until these systems are fully implemented. Although management continues to evaluate the effect to the Company's Condensed Consolidated Financial Statements and disclosures, management currently estimates total assets and liabilities will increase approximately $14.5 billion to $16.5 billion upon adoption, before considering deferred taxes. This estimate could change as the Company continues to progress with implementation and will also fluctuate based on the lease portfolio, discount rates and currency exchange rates as of the adoption date. Management does not expect a material impact to the Company’s Condensed Consolidated Statements of Income or Cash Flows. In June 2016, the FASB issued ASU 2016-13, Financial Instruments–Credit Losses (Topic 326) , which modifies the measurement of expected credit losses of certain financial instruments. The Company will adopt this ASU on February 1, 2020. Management is currently evaluating this ASU to determine its impact to the Company's Condensed Consolidated Financial Statements and disclosures.
