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. Certain previously reported amounts have been reclassified to conform to the current year presentation. 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, 2021 ("fiscal 2021"). 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 based on a calendar year. There were no significant intervening events during the month of October 2021 related to the consolidated operations 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 Condensed Consolidated Financial Statements have been prepared in conformity with GAAP. Those principles require management to make estimates and assumptions 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. Investments Investments in equity and debt securities are recorded in other long-term assets in the Condensed Consolidated Balance Sheets. Changes in fair value of equity securities measured on a recurring basis are recognized in other gains and losses in the Condensed Consolidated Statements of Income. Refer to Note 5 for details. Equity investments without readily determinable fair values are carried at cost and are adjusted for any observable price changes or impairments within other gains and losses in the Condensed Consolidated Statements of Income. Investments in debt securities classified as trading are reported at fair value with interest income recorded in interest income in the Condensed Consolidated Statements of Income. As of October 31, 2021, the Company had $1.0 billion in debt securities classified as trading. Indemnification Liabilities

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. As described in Note 1 , the Company measures the fair value of certain equity investments on a recurring basis in the accompanying Condensed Consolidated Balance Sheets. The fair value of the Company's equity investments measured on a recurring basis is as follows: (Amounts in millions) Fair Value as of October 31, 2021 Fair Value as of January 31, 2021 Equity investments measured using Level 1 inputs $ 6,124 $ 6,517 Equity investments measured using Level 2 inputs 6,340 7,905 Total $ 12,464 $ 14,422 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 October 31, 2021 and January 31, 2021, the notional amounts and fair values of these derivatives were as follows: October 31, 2021 January 31, 2021 (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 $ 4,719 $ 91 (1) $ 3,250 $ 166 (1) Receive fixed-rate, pay fixed-rate cross-currency swaps designated as net investment hedges — — 1,250 311 (1) Receive fixed-rate, pay fixed-rate cross-currency swaps designated as cash flow hedges 8,086 (881) (2) 5,073 (394) (2) Total $ 12,805 $ (790) $ 9,573 $ 83 (1) Classified primarily in other long-term assets within the Company's Condensed Consolidated Balance Sheets. (2) Classified primarily in deferred income taxes and other within the Company's Condensed Consolidated Balance Sheets. Nonrecurring Fair Value Measurements In addition to assets and liabilities 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. As of January 31, 2021, the Company's operations in the U.K. ("Asda") and operations in Japan ("Seiyu") met the held for sale criteria, and as a result the Company recorded non-recurring impairment charges in the fourth quarter of fiscal 2021 as the carrying value of the disposal groups exceeded their fair value, less costs to sell. Upon completing the sales of Asda in February 2021 and Seiyu in March 2021, the Company recorded incremental non-recurring impairment charges of $0.4 billion in the first quarter of fiscal 2022 within other gains and losses in the Condensed Consolidated Statements of Income. Refer to Note 6 . The Company did not have other material assets or liabilities resulting in nonrecurring fair value measurements as of October 31, 2021. 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, 2021 and January 31, 2021, are as follows: October 31, 2021 January 31, 2021 (Amounts in millions) Carrying Value Fair Value Carrying Value Fair Value Long-term debt, including amounts due within one year $ 38,000 $ 44,354 $ 44,309 $ 54,240

Divestitures	Divestitures During fiscal 2022, the Company completed the following transactions related to the Company's Walmart International segment. After closing these transactions, total assets of the Walmart International segment were $94.8 billion as of October 31, 2021, as compared to $109.4 billion as of January 31, 2021. Asda In February 2021, the Company completed the divestiture of Asda, the Company's retail operations in the U.K., for net consideration of $9.6 billion. Upon closing of the transaction, the Company recorded an incremental pre-tax loss of $0.2 billion in other gains and losses in its Condensed Consolidated Statement of Income in the first quarter of fiscal 2022, primarily related to changes in the net assets of the disposal group, currency exchange rate fluctuations and customary purchase price adjustments upon closing. During the first quarter of fiscal 2022, the Company deconsolidated the financial statements of Asda and recognized its retained investment in Asda as a debt security within other long-term assets and also recognized certain legal and tax indemnity liabilities within deferred income taxes and other on the Condensed Consolidated Balance Sheet.

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. Opioids Litigation In December 2017, the United States 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 payers, 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) (the "MDL") 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. The liability phase of a trial in one of the MDL cases began on October 4, 2021 against a number of parties, including the Company, regarding opioid dispensing claims. On November 23, 2021, the jury found in favor of the plaintiffs as to the liability of all defendants, including the Company. The Company intends to appeal this verdict. 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. On October 22, 2020, the Company filed a declaratory judgment action in the U.S. District Court for the Eastern District of Texas against the U.S. Department of Justice (the "DOJ") and the U.S. Drug Enforcement Administration, asking a federal court to clarify the roles and responsibilities of pharmacists and pharmacies as to the dispensing and distribution of opioids under the Controlled Substances Act (the "CSA"). The Company’s action was dismissed. The Company has appealed this decision to the Fifth Circuit and awaits the court's decision. On December 22, 2020, the DOJ filed a civil complaint in the U.S. District Court for the District of Delaware alleging that the Company unlawfully dispensed controlled substances from its pharmacies and unlawfully distributed controlled substances to those pharmacies. The complaint alleges that this conduct resulted in violations of the CSA. The DOJ is seeking civil penalties and injunctive relief. The Company filed a motion to dismiss the DOJ complaint on February 22, 2021. The DOJ filed its opposition brief on April 23, 2021 and the Company filed its reply brief on May 24, 2021. On November 19, 2021, the District Court stayed further proceedings in the DOJ complaint pending the decision of the United States Supreme Court in two consolidated cases (not involving Walmart) interpreting the CSA. In addition, the Company is the subject of two securities class actions alleging violations of the federal securities laws regarding the Company's disclosures with respect to opioids, filed in the U.S. District Court for the District of Delaware on January 20, 2021 and March 5, 2021 purportedly on behalf of a class of investors who acquired Walmart stock from March 30, 2016 through December 22, 2020. Those cases have been consolidated. On October 8, 2021, the defendants filed a motion to dismiss the consolidated securities action. Derivative actions were also filed by two of the Company's shareholders in the U.S. District Court for the District of Delaware on February 9, 2021 and April 16, 2021 alleging breach of fiduciary duties against certain of its current and former directors with respect to oversight of the Company's distribution and dispensing of opioids and also alleging violations of the federal securities laws and other breaches of duty by current directors and two current officers in connection with the Company's opioids disclosures. On September 27, 2021, three shareholders filed a derivative action in the Delaware Court of Chancery alleging that certain members of the current Board and certain former officers breached their fiduciary duties in failing to adequately oversee the Company's prescription opioids business. The Company cannot reasonably estimate any loss or range of loss that may arise from the various Opioids Litigation and intends to vigorously defend these litigation 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, eCommerce websites and other units located throughout the U.S., Africa, Canada, Central America, Chile, China, India and Mexico. 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 and other measures, including any corporate overhead allocations, as determined by the information regularly reviewed by its CODM. When the measurement of a segment significantly changes, previous period amounts and balances are reclassified to be comparable to the current period's presentation. Net sales by segment are as follows: Three Months Ended October 31, Nine Months Ended October 31, (Amounts in millions) 2021 2020 2021 2020 Net sales: Walmart U.S. $ 96,609 $ 88,353 $ 287,968 $ 270,378 Walmart International 23,627 29,554 73,962 86,487 Sam's Club 18,971 15,845 54,307 47,383 Net sales $ 139,207 $ 133,752 $ 416,237 $ 404,248 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) 2021 2020 2021 2020 Operating income (loss): Walmart U.S. $ 4,860 $ 4,589 $ 16,404 $ 13,948 Walmart International 871 1,078 2,926 2,696 Sam's Club 475 431 1,710 1,517 Corporate and support (414) (320) (985) (1,100) Operating income 5,792 5,778 20,055 17,061 Interest, net 442 516 1,456 1,700 Loss on extinguishment of debt 2,410 — 2,410 — Other (gains) and losses (1,207) (1,853) 2,275 (5,796) Income before income taxes $ 4,147 $ 7,115 $ 13,914 $ 21,157 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. Certain previously reported amounts have been reclassified to conform to the current year presentation. 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, 2021 ("fiscal 2021"). 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 based on a calendar year. There were no significant intervening events during the month of October 2021 related to the consolidated operations 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 Condensed Consolidated Financial Statements have been prepared in conformity with GAAP. Those principles require management to make estimates and assumptions 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.
Investments	Investments Investments in equity and debt securities are recorded in other long-term assets in the Condensed Consolidated Balance Sheets. Changes in fair value of equity securities measured on a recurring basis are recognized in other gains and losses in the Condensed Consolidated Statements of Income. Refer to Note 5
Indemnification Liabilities	Indemnification LiabilitiesThe Company has provided certain indemnifications in connection with its divestitures and has recorded indemnification liabilities equal to the estimated fair value of the obligations upon inception.
