Organization, Consolidation and Presentation of Financial Statements [Abstract]
Summary of Significant Accounting Policies	Summary of Significant 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, 2020 ("fiscal 2020 "). Therefore, the interim Condensed Consolidated Financial Statements should be read in conjunction with that Annual Report on Form 10-K. The Company's 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 significant intervening events during the month of July 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. Use of Estimates The Consolidated Financial Statements have been prepared in conformity with GAAP. Those principles require management to make estimates and assumptions, including potential impacts arising from the COVID-19 pandemic and related government actions, that affect the reported amounts of assets and liabilities. Management's estimates and assumptions also affect the disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results may differ materially from those estimates. Receivables In June 2016, the Financial Accounting Standards Board issued Accounting Standards Update (“ASU”) 2016-13, Financial Instruments–Credit Losses (Topic 326) , which modifies the measurement of expected credit losses of certain financial instruments. The Company adopted this ASU on February 1, 2020 with no material impact to the Company's Condensed Consolidated Financial Statements.

The Company did not have significant share-based awards outstanding that were anti-dilutive and not included in the calculation of diluted net income per common share attributable to Walmart for the three and six months ended July 31, 2020 and 2019 .

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 measures the fair value of equity investments (primarily its investment in JD.com) on a recurring basis and records them in other long-term assets in the accompanying Condensed Consolidated Balance Sheets. The fair value of the Company's equity investments are as follows: (Amounts in millions) Fair Value as of July 31, 2020 Fair Value as of January 31, 2020 Equity investments measured using Level 1 inputs $ 4,689 $ 2,715 Equity investments measured using Level 2 inputs 5,204 2,723 Total $ 9,893 $ 5,438 Derivatives The Company also has derivatives recorded at fair value. 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 July 31, 2020 and January 31, 2020 , the notional amounts and fair values of these derivatives were as follows: July 31, 2020 January 31, 2020 (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 $ 205 (1) $ 4,000 $ 97 (1) Receive fixed-rate, pay fixed-rate cross-currency swaps designated as net investment hedges 3,500 471 (1) 3,750 455 (1) Receive fixed-rate, pay fixed-rate cross-currency swaps designated as cash flow hedges 4,271 (748 ) (2) 4,067 (696 ) (2) Total $ 11,771 $ (72 ) $ 11,817 $ (144 ) (1) Classified in Other long-term assets within the Company's Condensed Consolidated Balance Sheets. (2) Classified in Deferred income taxes and other within the Company's Condensed Consolidated Balance Sheets. 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, assets are recorded at fair value on a nonrecurring basis as a result of impairment charges. The Company did not have any material assets or liabilities subject to nonrecurring fair value measurements as of July 31, 2020 . 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 July 31, 2020 and January 31, 2020 , are as follows: July 31, 2020 January 31, 2020 (Amounts in millions) Carrying Value Fair Value Carrying Value Fair Value Long-term debt, including amounts due within one year $ 46,512 $ 58,357 $ 49,076 $ 57,769

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 or settled by the Company, individually or in the aggregate, may result in a liability material to the Company's financial condition, results of operations or cash flows. ASDA Equal Value Claims ASDA Stores Ltd. ("Asda"), a wholly-owned subsidiary of the Company, is a defendant in over 40,000 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 ("U.K.") 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 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 employees working in Asda's warehouse and distribution facilities, and that the difference in pay between these job positions disparately impacts women because more women work in retail stores while more men work in warehouses and distribution facilities, and that the pay difference is not objectively justified. The 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. In October 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. Asda appealed the ruling and the oral argument was held before the Supreme Court of the United Kingdom in July 2020. The Company is awaiting a decision. Notwithstanding the appeal, claimants are 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. Accordingly, the Company can provide no assurance as to the scope and outcomes 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. The Company believes it has substantial factual and legal defenses to these claims, and intends to defend the claims vigorously. Prescription Opiate Litigation and Other Matters In December 2017, the U.S. Judicial Panel on Multidistrict Litigation consolidated numerous lawsuits filed against a wide array of defendants by various plaintiffs, including counties, cities, healthcare providers, Native American tribes, individuals, and third-party payors, asserting claims generally concerning the impacts of widespread opioid abuse. The consolidated multidistrict litigation entitled In re National Prescription Opiate Litigation (MDL No. 2804), 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 also been filed in state courts by state, local and tribal governments, health care providers and other plaintiffs. Plaintiffs are seeking compensatory and punitive damages, as well as injunctive relief including abatement. The Company cannot predict the number of such claims that may be filed, but 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 and distribution practices involving opioids. The Company cannot reasonably estimate any loss or range of loss that may arise from these matters. Accordingly, 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.

Segment Reporting Information, Profit (Loss) [Abstract]
Segments and Disaggregated Revenue	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. 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. The Walmart U.S. segment includes the Company's mass merchandising concept in the U.S., as well as eCommerce and omni-channel initiatives. The Walmart International segment consists of the Company's operations outside of the U.S., as well as eCommerce and omni-channel initiatives. The Sam's Club segment includes the warehouse membership clubs in the U.S., as well as samsclub.com and omni-channel initiatives. 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. When the measurement of a segment changes, previous period amounts and balances are reclassified to be comparable to the current period's presentation. Beginning with the first quarter in fiscal 2021, the Company revised its definition of eCommerce net sales to include certain pharmacy transactions and, accordingly, revised prior period amounts to maintain comparability. Net sales by segment are as follows: Three Months Ended July 31, Six Months Ended July 31, (Amounts in millions) 2020 2019 2020 2019 Net sales: Walmart U.S. $ 93,282 $ 85,200 $ 182,025 $ 165,544 Walmart International 27,167 29,139 56,933 57,914 Sam's Club 16,375 15,049 31,538 28,879 Net sales $ 136,824 $ 129,388 $ 270,496 $ 252,337 Operating income by segment, as well as operating loss for corporate and support, interest, net and other gains and losses are as follows: Three Months Ended July 31, Six Months Ended July 31, (Amounts in millions) 2020 2019 2020 2019 Operating income (loss): Walmart U.S. $ 5,057 $ 4,659 $ 9,359 $ 8,801 Walmart International 812 893 1,618 1,631 Sam's Club 592 480 1,086 931 Corporate and support (402 ) (449 ) (780 ) (835 ) Operating income 6,059 5,583 11,283 10,528 Interest, net 635 585 1,184 1,210 Other (gains) and losses (3,222 ) 85 (3,943 ) (752 ) Income before income taxes $ 8,646 $ 4,913 $ 14,042 $ 10,070 Disaggregated Revenues In the following tables, segment net sales are disaggregated by either merchandise category or by market. From time to time, the Company revises the assignment of net sales of a particular item to a merchandise category. When the assignment changes, previous period amounts are reclassified to be comparable to the current period's presentation. In addition, net sales related to eCommerce are provided for each segment, which include omni-channel sales, where a customer initiates an order digitally and the order is fulfilled through a store or club.

Organization, Consolidation and Presentation of Financial Statements [Abstract]
Basis of Presentation	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, 2020 ("fiscal 2020 "). Therefore, the interim Condensed Consolidated Financial Statements should be read in conjunction with that Annual Report on Form 10-K. The Company's 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 significant intervening events during the month of July 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.
Use of Estimates	Use of Estimates The Consolidated Financial Statements have been prepared in conformity with GAAP. Those principles require management to make estimates and assumptions, including potential impacts arising from the COVID-19 pandemic and related government actions, that affect the reported amounts of assets and liabilities. Management's estimates and assumptions also affect the disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results may differ materially from those estimates.
New Accounting Pronouncements	In June 2016, the Financial Accounting Standards Board issued Accounting Standards Update (“ASU”) 2016-13, Financial Instruments–Credit Losses (Topic 326) , which modifies the measurement of expected credit losses of certain financial instruments. The Company adopted this ASU on February 1, 2020 with no material impact to the Company's Condensed Consolidated Financial Statements.
Receivables	Receivables are stated at their carrying values, net of a reserve for credit losses, and are primarily due from the following: customers, which also includes insurance companies resulting from pharmacy sales, banks for customer credit, debit cards and electronic transfer transactions that take in excess of seven days to process; suppliers for marketing or incentive programs; governments for income taxes; and real estate transactions.
