BASIS OF PRESENTATION	6 Months Ended
BASIS OF PRESENTATION	Jun. 30, 2026
Organization, Consolidation and Presentation of Financial Statements [Abstract]
BASIS OF PRESENTATION	BASIS OF PRESENTATION The condensed consolidated financial statements present the results of operations, financial position, and cash flows of Marriott International, Inc. and its consolidated subsidiaries (referred to in this report as “we,” “us,” “Marriott,” or the “Company”). In order to make this report easier to read, we also refer throughout to (1) our Condensed Consolidated Financial Statements as our “Financial Statements,” (2) our Condensed Consolidated Statements of Income as our “Income Statements,” (3) our Condensed Consolidated Balance Sheets as our “Balance Sheets,” (4) our Condensed Consolidated Statements of Cash Flows as our “Statements of Cash Flows,” (5) our properties, brands, or markets in the United States and Canada as “U.S. & Canada,” and (6) our properties, brands, or markets in our Europe, Middle East & Africa, Greater China, Asia Pacific excluding China, and Caribbean & Latin America regions, as “International.” References throughout to numbered “Notes” refer to these Notes to Condensed Consolidated Financial Statements, unless otherwise stated. In addition, we use the term “hotel owners” throughout this report to refer, collectively, to owners of hotels and other lodging offerings operating in our system pursuant to franchise agreements, management agreements, license agreements, or similar arrangements, and we use the term “hotels in our system” to refer to hotels and other lodging offerings operating in our system pursuant to such arrangements, as well as hotels that we own or lease. The terms “hotel owners” and “hotels in our system” exclude Homes & Villas by Marriott BonvoySM (which we also exclude from our property and room count), timeshare, residential, and The Ritz-Carlton Yacht Collection®. These Financial Statements have not been audited. We have condensed or omitted certain information and disclosures normally included in financial statements presented in accordance with U.S. generally accepted accounting principles (“GAAP”). The Financial Statements in this report should be read in conjunction with the consolidated financial statements and notes thereto in our Annual Report on Form 10-K for the fiscal year ended December 31, 2025 (“2025 Form 10-K”). Certain terms not otherwise defined in this Form 10-Q have the meanings specified in our 2025 Form 10-K. Preparation of financial statements that conform with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities as of the date of the financial statements, the reported amounts of revenues and expenses during the reporting periods, and the disclosures of contingent liabilities. Accordingly, ultimate results could differ from those estimates. The accompanying Financial Statements reflect all normal and recurring adjustments necessary to present fairly our financial position as of June 30, 2026 and December 31, 2025, the results of our operations for the three and six months ended June 30, 2026 and June 30, 2025, and cash flows for the six months ended June 30, 2026 and June 30, 2025. Interim results may not be indicative of fiscal year performance because of seasonal and short-term variations. We have eliminated all material intercompany transactions and balances between entities consolidated in these Financial Statements and reclassified certain prior period amounts to conform to our current period presentation. New Accounting Standards Not Yet Adopted Accounting Standards Update (“ASU”) 2025-06 - “Targeted Improvements to the Accounting for Internal-Use Software” (Topic 350). ASU 2025-06 eliminates references to software development project stages and revises the criteria that must be met to begin capitalizing internal-use software costs. The standard permits entities to adopt the guidance using a prospective, retrospective, or modified transition approach and becomes effective for us beginning January 1, 2028, with early adoption permitted. We are currently assessing the potential impact that ASU 2025-06 will have on our financial statements and disclosures.

DISPOSITION	6 Months Ended
DISPOSITION	Jun. 30, 2026
Discontinued Operations and Disposal Groups [Abstract]
DISPOSITION	DISPOSITION In April 2026, a U.S. & Canada hotel met the accounting criteria to be designated as an asset held for sale. We determined that the carrying amount of the hotel exceeded its fair value less costs to sell, based on a purchase and sale agreement with a third-party buyer, and recorded an impairment charge of $68 million in the “Depreciation, amortization, and other” caption of our Income Statements. In May 2026, we completed the sale of the hotel and entered into a long-term management agreement to operate the hotel.

STOCK-BASED COMPENSATION	6 Months Ended
STOCK-BASED COMPENSATION	Jun. 30, 2026
Share-Based Payment Arrangement [Abstract]
STOCK-BASED COMPENSATION	STOCK-BASED COMPENSATION We granted 0.5 million restricted stock units (“RSUs”) during the 2026 first half to certain executives and other employees, and those units vest generally over three or four years in equal annual installments commencing one year after the grant date. We also granted 0.1 million performance-based RSUs (“PSUs”) in the 2026 first half to certain executives and other senior-level employees, which are earned subject to continued employment and the satisfaction of certain performance and market conditions based on the degree of achievement of pre-established targets for 2028 adjusted EBITDA performance and relative total stockholder return over the 2026 to 2028 performance period. RSUs, including PSUs, granted in the 2026 first half had a weighted average grant-date fair value of $345 per unit. We recorded stock-based compensation expense for RSUs and PSUs of $55 million in the 2026 second quarter, $49 million in the 2025 second quarter, $101 million in the 2026 first half, and $92 million in the 2025 first half. Deferred compensation costs for unvested awards for RSUs and PSUs totaled $279 million as of June 30, 2026.

Segment Reporting [Abstract]

BUSINESS SEGMENTS

We discuss our operations in the following four reportable business segments: (1) U.S. & Canada, (2) Europe, Middle East & Africa (“EMEA”), (3) Greater China, and (4) Asia Pacific excluding China (“APEC”). Our Caribbean & Latin America (“CALA”) operating segment does not meet the applicable accounting criteria for separate disclosure as a reportable business segment, and as such, we include its results in “Unallocated corporate and other.”

Our President and Chief Executive Officer, who is our “chief operating decision maker” (“CODM”), evaluates the performance of our operating segments using “segment profits,” which is based largely on the results of the segment without allocating corporate expenses, income taxes, indirect general and administrative expenses, or restructuring and merger-related charges, and other expenses. We assign gains and losses, equity in earnings or losses, and direct general and administrative expenses to each of our segments. “Unallocated corporate and other” includes a portion of our revenues (such as fees we receive from our credit card programs and timeshare licensing agreements), revenues and expenses for our Loyalty Program, indirect general and administrative expenses, restructuring and merger-related charges, and other expenses, equity in earnings or losses, and other gains or losses that we do not allocate to our segments, as well as results of our CALA operating segment.

Our CODM uses segment profits to allocate resources (including employees and investment spending) to each segment, primarily as part of the annual budget process. Our CODM reviews budget-to-actual variances on a quarterly basis to assess segment performance. Additionally, our CODM uses segment profits to compare the results of each segment with one another and in the determination of compensation for segment leadership.

Our CODM monitors assets for the consolidated Company but does not use assets by operating segment when assessing performance or making operating segment resource allocations.

CONTRACTS WITH CUSTOMERS	Jun. 30, 2026
Revenue from Contract with Customer [Abstract]
CONTRACTS WITH CUSTOMERS	CONTRACTS WITH CUSTOMERS Our current and noncurrent liability for guest loyalty program increased by $452 million, to $8,444 million as of June 30, 2026, from $7,992 million as of December 31, 2025, primarily reflecting points earned by members. The increase was partially offset by $1,802 million of revenue recognized in the 2026 first half, that was deferred as of December 31, 2025. The current portion of our liability for guest loyalty program increased by $183 million compared to December 31, 2025, mainly due to higher estimated redemptions in the short-term. Our allowance for credit losses was $215 million as of June 30, 2026 and $212 million as of December 31, 2025.

- Definition

The entire disclosure of revenue from contract with customer to transfer good or service and to transfer nonfinancial asset. Includes, but is not limited to, disaggregation of revenue, credit loss recognized from contract with customer, judgment and change in judgment related to contract with customer, and asset recognized from cost incurred to obtain or fulfill contract with customer. Excludes insurance and lease contracts.

Basis of Accounting	These Financial Statements have not been audited. We have condensed or omitted certain information and disclosures normally included in financial statements presented in accordance with U.S. generally accepted accounting principles (“GAAP”). The Financial Statements in this report should be read in conjunction with the consolidated financial statements and notes thereto in our Annual Report on Form 10-K for the fiscal year ended December 31, 2025 (“2025 Form 10-K”). Certain terms not otherwise defined in this Form 10-Q have the meanings specified in our 2025 Form 10-K. Preparation of financial statements that conform with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities as of the date of the financial statements, the reported amounts of revenues and expenses during the reporting periods, and the disclosures of contingent liabilities. Accordingly, ultimate results could differ from those estimates. The accompanying Financial Statements reflect all normal and recurring adjustments necessary to present fairly our financial position as of June 30, 2026 and December 31, 2025, the results of our operations for the three and six months ended June 30, 2026 and June 30, 2025, and cash flows for the six months ended June 30, 2026 and June 30, 2025. Interim results may not be indicative of fiscal year performance because of seasonal and short-term variations. We have eliminated all material intercompany transactions and balances between entities consolidated in these Financial Statements and reclassified certain prior period amounts to conform to our current period presentation.
New Accounting Standards Not Yet Adopted	New Accounting Standards Not Yet Adopted Accounting Standards Update (“ASU”) 2025-06 - “Targeted Improvements to the Accounting for Internal-Use Software” (Topic 350). ASU 2025-06 eliminates references to software development project stages and revises the criteria that must be met to begin capitalizing internal-use software costs. The standard permits entities to adopt the guidance using a prospective, retrospective, or modified transition approach and becomes effective for us beginning January 1, 2028, with early adoption permitted. We are currently assessing the potential impact that ASU 2025-06 will have on our financial statements and disclosures.

Starwood Data Security Incident

Description of Event

On November 30, 2018, we announced a data security incident involving unauthorized access to the Starwood Hotels & Resorts Worldwide, LLC, formerly known as Starwood Hotels & Resorts Worldwide, Inc. (“Starwood”), reservations database (the “Data Security Incident”). We discontinued use of the Starwood reservations database for business operations at the end of 2018.

Litigation, Claims, and Government Investigations

Following our announcement of the Data Security Incident, approximately 100 lawsuits were filed by consumers and others against us in U.S. federal, U.S. state and Canadian courts related to the incident. The plaintiffs in these cases, who generally purport to represent various classes of consumers, generally claim to have been harmed by alleged actions and/or omissions by the Company in connection with the Data Security Incident and assert a variety of common law and statutory claims seeking monetary damages, injunctive relief, costs and attorneys’ fees, and other related relief. The U.S. cases were consolidated in the U.S. District Court for the District of Maryland (the “District Court”), pursuant to orders of the U.S. Judicial Panel on Multidistrict Litigation (the “MDL”). In 2025, the U.S. Court of Appeals for the Fourth Circuit reversed the District Court’s certification of a class of consumer plaintiffs for the second time, and some plaintiffs subsequently filed lawsuits in New York state court on an individual basis, alleging violations of New York statutory law and seeking monetary damages, attorneys’ fees, and other related relief. We are progressing in our mediation discussions with the U.S. consumer plaintiffs, and we believe it is probable that we will incur losses in relation to these cases. As of June 30, 2026, we have recorded an accrual for an estimated loss contingency related to these matters, which is not material to our Financial Statements. The Canadian cases remain pending. We dispute the allegations in these lawsuits and are vigorously defending against such claims.

In addition, most inquiries and investigations by U.S. federal, U.S. state and foreign governmental authorities have been resolved or no longer appear to be active.

While we believe it is reasonably possible that we may incur losses in excess of the amounts recorded associated with the above-described lawsuits or regulatory investigations related to the Data Security Incident, it is not possible to reasonably estimate the amount of such losses or range of loss in excess of the amounts recorded that might result from adverse judgments, settlements, or other resolution of these proceedings based on: (1) in the case of the above-described lawsuits, the current stage of these proceedings, the absence of specificity as to alleged damages, the uncertainty as to the certification of a class or classes and the size of any certified class, and the lack of resolution of significant factual and legal issues, and (2) uncertainty regarding regulatory inquiries or investigations.

Other Legal Proceedings

We have been and are currently party to other legal proceedings involving claims that we infringe the intellectual property rights of others. At this time, we do not expect these proceedings to have a material impact on the Company’s business, financial condition, results of operations, or cash flows.

We paid cash for interest, net of amounts capitalized, of $381 million in the 2026 first half and $328 million in the 2025 first half.

We are party to a $4.5 billion multicurrency revolving credit agreement (as amended, the “Credit Facility”). Available borrowings under the Credit Facility support our commercial paper program and general corporate needs. U.S. dollar borrowings under the Credit Facility bear interest at SOFR (the Secured Overnight Financing Rate) plus a spread based on our public debt rating. We also pay quarterly fees on the Credit Facility at a rate based on our public debt rating. We classify outstanding borrowings under the Credit Facility and outstanding commercial paper borrowings (which generally have short-term maturities of 45 days or less) as long-term based on our ability and intent to refinance the outstanding borrowings on a long-term basis. The Credit Facility expires on December 14, 2027.

In February 2026, we issued $600 million aggregate principal amount of 4.500 percent Series WW Notes due May 1, 2033 (the “Series WW Notes”) and $850 million aggregate principal amount of 5.100 percent Series XX Notes due May 1, 2038 (the “Series XX Notes”). We will pay interest on the Series WW Notes and Series XX Notes in May and November of each year, commencing in November 2026. Net proceeds from the offering of the Series WW Notes and Series XX Notes were approximately $1.425 billion, after deducting the underwriting discount and expenses, and were made available for general corporate purposes, including working capital, capital expenditures, acquisitions, stock repurchases, or repayment of outstanding indebtedness.

We determine the fair value of our Senior Notes using quoted market prices, which are directly observable Level 1 inputs. As of June 30, 2026 and December 31, 2025, the fair value of our noncurrent Senior Notes was $15,039 million (carrying amount of $15,090 million) and $13,836 million (carrying amount of $13,686 million), respectively. The carrying amount of our commercial paper borrowings approximates fair value due to their short maturity and because they bear interest at a market rate. See the “Fair Value Measurements” caption of Note 2 and Note 12 of our 2025 Form 10-K for more information on the input levels we use in determining fair value.

INCOME TAXES	6 Months Ended
INCOME TAXES	Jun. 30, 2026
Income Tax Disclosure [Abstract]
INCOME TAXES	INCOME TAXES Our effective tax rate decreased to 26.6 percent for the 2026 second quarter compared to 27.6 percent for the 2025 second quarter, primarily due to lower tax on non-U.S. income. Our effective tax rate increased to 25.7 percent for the 2026 first half compared to 21.4 percent for the 2025 first half, primarily due to the prior year release of tax reserves, partially offset by lower tax on non-U.S. income. We paid cash for income taxes, net of refunds, of $350 million in the 2026 first half and $534 million in the 2025 first half.

- Definition

The entire disclosure for income tax.
