Accounting Policies [Abstract]
BASIS OF PRESENTATION AND SIGNIFICANT ACCOUNTING POLICIES	BASIS OF PRESENTATION AND SIGNIFICANT ACCOUNTING POLICIES Basis of presentation . As permitted by the rules and regulations of the Securities and Exchange Commission (“SEC”), certain information and footnote disclosures normally included in financial statements prepared in accordance with U.S. generally accepted accounting principles (“U.S. GAAP”) have been condensed or omitted. These consolidated financial statements should be read in conjunction with the Company’s 2022 annual consolidated financial statements and notes thereto included in the Company’s Annual Report on Form 10-K for the year ended December 31, 2022. In the opinion of management, the accompanying unaudited consolidated financial statements contain all adjustments, which include only normal recurring adjustments, necessary to present fairly the Company’s interim financial statements. The results for such periods are not necessarily indicative of the results to be expected for the full year. Principles of consolidation . The Company evaluates entities for which control is achieved through means other than voting rights to determine if it is the primary beneficiary of a variable interest entity (“VIE”). The Company consolidates its investment in a VIE when it determines that it is its primary beneficiary. The Company may change its original assessment of a VIE upon subsequent events such as the modification of contractual arrangements that affect the characteristics or adequacy of the entity’s equity investments at risk and the disposition of all or a portion of an interest held by the primary beneficiary. The Company performs this analysis on an ongoing basis. The Company has a 5% ownership interest in the venture that owns and leases back the real estate assets of Bellagio (the “Bellagio BREIT Venture”). Bellagio BREIT Venture is a VIE of which the Company is not the primary beneficiary and, accordingly, the Company does not consolidate the venture. The Company’s maximum exposure to loss in Bellagio BREIT Venture is equal to the carrying value of its investment of $55 million as of September 30, 2023, assuming no future capital funding requirements, plus the exposure to loss resulting from the Company’s guarantee of the debt of Bellagio BREIT Venture, which guarantee is immaterial as of September 30, 2023, as further discussed in Note 9. For entities determined not to be a VIE, the Company consolidates such entities in which the Company owns 100% of the equity. For entities in which the Company owns less than 100% of the equity interest, the Company consolidates the entity under the voting interest model if it has a controlling financial interest based upon the terms of the respective entities’ ownership agreements, such as MGM China. For these entities, the Company records a noncontrolling interest in the consolidated balance sheets and all intercompany balances and transactions are eliminated in consolidation. If the entity does not qualify for consolidation under the voting interest model and the Company has significant influence over the operating and financial decisions of the entity, the Company generally accounts for the entity under the equity method, such as BetMGM, which does not qualify for consolidation as the Company has joint control, given the entity is structured with substantive participating rights whereby both owners participate in the decision making process, which prevents the Company from exerting a controlling financial interest in such entity, as defined in Accounting Standards Codification (“ASC”) 810. For entities over which the Company does not have significant influence, the Company accounts for its equity investment under ASC 321. Fair value measurements . Fair value measurements affect the Company’s accounting and impairment assessments of its long-lived assets, investments in unconsolidated affiliates or equity interests, assets acquired, and liabilities assumed in an acquisition, and goodwill and other intangible assets. Fair value measurements also affect the Company’s accounting for certain of its financial assets and liabilities. Fair value is defined as the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date and is measured according to a hierarchy that includes: Level 1 inputs, such as quoted prices in an active market; Level 2 inputs, which are quoted prices for identical or comparable instruments or pricing using observable market data; or Level 3 inputs, which are unobservable inputs. The Company used the following inputs in its fair value measurements: • Level 1 inputs when measuring its equity investments recorded at fair value; • Level 2 inputs for its long-term debt fair value disclosures; See Note 6; • Level 1 and Level 2 inputs for its debt investments; and • Level 1, Level 2, and Level 3 inputs when assessing the fair value of assets acquired and liabilities assumed in acquisitions. See Note 3. Equity investments. Fair value is measured based upon trading prices on the applicable securities exchange for equity investments for which the Company has elected the fair value option of ASC 825 and equity investments accounted for under ASC 321 that have a readily determinable fair value. The fair value of these investments was $409 million and $461 million as of September 30, 2023 and December 31, 2022, respectively, and is reflected within “Other long-term assets, net” on the consolidated balance sheets. Gains and losses are recorded in “Other, net” in the statements of operations. For the three and nine months ended September 30, 2023, the Company recorded a net loss on its equity investments of $57 million and $52 million, respectively. For the three and nine months ended September 30, 2022, the Company recorded a net loss on its equity investments of $20 million and $28 million, respectively. Debt investments. The Company’s investments in debt securities are classified as trading securities and recorded at fair value. Gains and losses are recorded in “Other, net” in the statements of operations. Debt securities are considered cash equivalents if the criteria for such classification is met or otherwise classified as short-term investments within “Prepaid expenses and other” since the investment of cash is available for current operations. The following tables present information regarding the Company’s debt investments: Fair value level September 30, 2023 December 31, 2022 (In thousands) Cash and cash equivalents: Money market funds Level 1 $ 174,585 $ 12,009 Commercial paper Level 2 — 5,992 Cash and cash equivalents 174,585 18,001 Short-term investments: U.S. government securities Level 1 42,132 56,835 U.S. agency securities Level 2 25,744 9,530 Commercial paper and certificates of deposit Level 2 — 4,466 Corporate bonds Level 2 392,585 213,875 Asset-backed securities Level 2 2,420 — Short-term investments 462,881 284,706 Total debt investments $ 637,466 $ 302,707 Cash and cash equivalents. Cash and cash equivalents consist of cash and highly liquid investments with maturities of 90 days or less at the date of purchase. The fair value of cash and cash equivalents approximates carrying value because of the short maturity of those instruments (Level 1). Restricted cash. MGM China’s pledged cash of $87 million and $124 million as of September 30, 2023 and December 31, 2022, respectively, securing the bank guarantees discussed in Note 9 is restricted in use and classified within “Other long-term assets, net.” Such amounts plus “Cash and cash equivalents” on the consolidated balance sheets equal “Cash, cash equivalents, and restricted cash” on the consolidated statements of cash flows as of September 30, 2023 and December 31, 2022. Accounts receivable. As of September 30, 2023 and December 31, 2022, the loss reserve on accounts receivable was $131 million and $113 million, respectively. Note receivable. In February 2023, the secured note receivable related to the sale of Circus Circus Las Vegas and the adjacent land was repaid, prior to maturity, for $170 million, which approximated its carrying value on the date of repayment. As of December 31, 2022, the carrying value of the note receivable was $167 million and was recorded within “Other long-term assets, net” on the consolidated balance sheets. Accounts payable. As of September 30, 2023 and December 31, 2022, the Company had accrued $56 million and $80 million, respectively, for purchases of property and equipment within “Accounts and construction payable” on the consolidated balance sheets. Revenue recognition. Contract and Contract-Related Liabilities . There may be a difference between the timing of cash receipts from the customer and the recognition of revenue, resulting in a contract or contract-related liability. The Company generally has three types of liabilities related to contracts with customers: (1) outstanding chip liability, which represents the amounts owed in exchange for gaming chips held by a customer, (2) loyalty program obligations, which represents the deferred allocation of revenue relating to loyalty program incentives earned, and (3) customer advances and other, which is primarily funds deposited by customers before gaming play occurs (“casino front money”) and advance payments on goods and services yet to be provided, such as advance ticket sales and deposits on rooms and convention space or for unpaid wagers. These liabilities are generally expected to be recognized as revenue within one year of being purchased, earned, or deposited and are recorded within “Other accrued liabilities” on the consolidated balance sheets. The following table summarizes the activity related to contract and contract-related liabilities: Outstanding Chip Liability Loyalty Program Customer Advances and Other 2023 2022 2023 2022 2023 2022 (In thousands) Balance at January 1 $ 185,669 $ 176,219 $ 183,602 $ 144,465 $ 816,376 $ 640,001 Balance at September 30 185,615 156,560 204,333 175,716 847,572 747,505 Increase / (decrease) $ (54) $ (19,659) $ 20,731 $ 31,251 $ 31,196 $ 107,504 The January 1, 2023 balances exclude liabilities related to assets held for sale. Revenue by source. The Company presents the revenue earned disaggregated by the type or nature of the good or service (casino, room, food and beverage, and entertainment, retail and other) and by relevant geographic region within Note 12. Leases. The Company determines if an arrangement is or contains a lease at inception or modification of the arrangement. An arrangement is or contains a lease if there are identified assets and the right to control the use of an identified asset is conveyed for a period of time in exchange for consideration. Control over the use of the identified asset means the lessee has both the right to obtain substantially all of the economic benefits from the use of the asset and the right to direct the use of the asset. The Company classifies a lease with terms greater than twelve months as either operating or finance. At commencement, the right-of-use (“ROU”) assets and lease liabilities are recognized based on the present value of the future minimum lease payments over the lease term. The initial measurement of ROU assets also includes any prepaid lease payments and are reduced by any previously accrued deferred rent. When available, such as for the Company’s triple-net operating leases for which the lessor has provided its implicit rate or provided the assumptions required for the Company to readily determine the rate implicit in the lease, the Company uses the rate implicit in the lease to discount lease payments to present value. However, for most of the Company’s leases, such as its ground subleases and equipment leases, the Company cannot readily determine the implicit rate. Accordingly, the Company uses its incremental borrowing rate to discount the lease payments for such leases based on the information available at the commencement date. Lease terms include options to extend or terminate the lease when it is reasonably certain that such option will be exercised. The Company’s triple-net operating leases each contain renewal periods at the Company’s option, each of which are not considered to be reasonably certain of being exercised. Many of the Company’s leases include fixed rental escalation clauses that are factored into the determination of lease payments. For operating leases, lease expense for minimum lease payments is recognized on a straight-line basis over the expected lease term. For finance leases, the ROU asset depreciates on a straight-line basis over the shorter of the lease term or useful life of the ROU asset and the lease liability accretes interest based on the interest method using the discount rate determined at lease commencement. Refer to Note 8 for discussion of leases under which the Company is a lessee. The Company is a lessor under certain other lease arrangements. Lease revenues earned by the Company from third parties are classified within the line item corresponding to the type or nature of the tenant’s good or service . For the three and nine months ended September 30, 2023, lease revenues from third-party tenants include $20 million and $57 million recorded within food and beverage revenue, respectively, and $27 million and $86 million recorded within entertainment, retail, and other revenue for the same such periods, respectively. For the three and nine months ended September 30, 2022, lease revenues from third-party tenants include $19 million and $52 million recorded within food and beverage revenue, respectively, and $30 million and $85 million recorded within entertainment, retail, and other revenue for the same such periods, respectively. Lease revenues from the rental of hotel rooms are recorded as rooms revenues within the consolidated statements of operations. Redeemable noncontrolling interest. Noncontrolling interests with redemption features, such as put rights, that are not exclusively in the Company’s control, are considered redeemable noncontrolling interests. Redeemable noncontrolling interests are presented outside of stockholders’ equity within the mezzanine section of the accompanying consolidated balance sheets. The interests are initially accounted for at fair value and subsequently adjusted to the greater of the redemption value and carrying value (initial fair value adjusted for attributed net income (loss) and distributions, as applicable). The Company records such adjustments to capital in excess of par value. During the nine months ended September 30, 2023 and 2022, the Company purchased $138 million and $21 million of interests from its redeemable noncontrolling interest parties, respectively. Share repurchases. Shares repurchased pursuant to the Company’s share repurchase plans are retired upon purchase. The cost of the repurchases in excess of the aggregate par value of the shares reduces capital in excess of par value, to the extent available, with any residual cost applied against retained earnings.

Business Combination and Asset Acquisition [Abstract]
ACQUISITIONS AND DIVESTITURES	ACQUISITIONS AND DIVESTITURES Push Gaming acquisition. On August 31, 2023, LeoVegas acquired 86% of digital gaming developer, Push Gaming Holding Limited (“Push Gaming”) for total consideration of $145 million, which was preliminarily allocated to $126 million of goodwill and $40 million of amortizable intangible assets. LeoVegas acquisition. On May 2, 2022, the Company commenced a public offer to the shareholders of LeoVegas to tender 100% of the shares at a price of SEK 61 in cash per share. On September 7, 2022, the Company completed its tender offer and acquired 65% of the outstanding shares of LeoVegas and, at the completion of an extended acceptance period on September 22, 2022, acquired an additional 2% of outstanding shares, for an aggregate cash tender price of $370 million. During the tender offer period, the Company had acquired 31% of outstanding shares in open market purchases that had an acquisition-date fair value of approximately $172 million. As the Company’s previous 31% ownership interest was accounted for at fair value, no gain or loss was recorded upon consolidation. The remaining outstanding shares, with a fair value of approximately $11 million based upon the tender price, were settled by the Company in cash in connection with squeeze-out proceedings during the second quarter of 2023. The acquisition provided the Company an opportunity to create a scaled global online gaming business. The Company recognized 100% of the assets, liabilities, and noncontrolling interests of LeoVegas at fair value at the date of the acquisition. The fair value of the acquired equity interests of LeoVegas was determined by the tender price and equaled $556 million, inclusive of cash settlement of equity awards. Under the acquisition method, the fair value was allocated to the assets acquired, liabilities assumed, and noncontrolling interests. T he Company estimated fair value using level 1 inputs, level 2 inputs, and level 3 inputs. The estimated fair values of the identified intangible assets were determined using methodologies under the income approach based on significant inputs that were not observable. The intangible assets include trademarks, which is an indefinite-lived intangible asset, and customer lists and technology, which are finite-lived intangibles that are amortized over each of their estimated useful lives of five years. Goodwill is primarily attributable to the profitability of LeoVegas in excess of identifiable assets and is not deductible for tax purposes. All of the goodwill was assigned to Corporate and other. The following table sets forth the purchase price allocation (in thousands): Cash and cash equivalents $ 93,407 Receivables and other current assets 36,872 Technology 109,027 Trademarks 144,374 Customer lists 126,526 Goodwill 288,367 Other long-term assets 19,181 Accounts payable, accrued liabilities, and other current liabilities (118,302) Debt (104,439) Other long-term liabilities (36,457) Noncontrolling interests (2,861) $ 555,695 The operating results for LeoVegas are included in the consolidated statements of operations from the date of acquisition. LeoVegas’s net revenue for the period from September 7, 2022 through September 30, 2022 was $31 million and operating loss and net loss were $3 million and $4 million, respectively. The Cosmopolitan acquisition. On May 17, 2022, the Company acquired 100% of the equity interests in the entities that own the operations of The Cosmopolitan for cash consideration of $1.625 billion plus working capital adjustments for a total purchase price of approximately $1.7 billion. The acquisition expands the Company’s customer base and provides a greater depth of choices and experiences for guests in Las Vegas. The Company recognized 100% of the acquired assets and assumed liabilities at fair value at the date of the acquisition. Under the acquisition method, the fair value was allocated to the assets acquired and liabilities assumed in the transaction. The Company estimated fair value using level 1 inputs, level 2 inputs, and level 3 inputs. The estimated fair values of the identified intangible assets were determined using methodologies under the income approach based on significant inputs that were not observable. The intangible assets include trademarks, which is an indefinite-lived intangible asset, and customer lists, which is amortized over its estimated useful life of seven years. Goodwill, which is deductible for tax purposes, is primarily attributable to the profitability of The Cosmopolitan in excess of identifiable assets as well as expected synergies. All of the goodwill was assigned to the Las Vegas Strip Resorts segment. The following table sets forth the purchase price allocation (in thousands): Cash and cash equivalents $ 80,670 Receivables and other current assets 94,354 Property and equipment 120,912 Trademarks 130,000 Customer lists 95,000 Goodwill 1,289,468 Operating lease right-of-use-assets, net 3,404,894 Other long-term assets 23,709 Accounts payable, accrued liabilities, and other current liabilities (145,136) Operating lease liabilities (3,401,815) Other long-term liabilities (1,570) $ 1,690,486 The operating results for The Cosmopolitan are included in the consolidated statements of operations from the date of acquisition. The Cosmopolitan’s net revenue for the period from May 17, 2022 through September 30, 2022 was $465 million and operating income and net income were each $57 million. Unaudited pro forma information - The Cosmopolitan acquisition . The following unaudited pro forma consolidated financial information for the Company has been prepared assuming the Company’s acquisition of The Cosmopolitan had occurred as of January 1, 2021. The unaudited pro forma financial information below is not necessarily indicative of either future results of operations or results that might have been achieved had the acquisition been consummated as of the indicated date. Pro forma results of operations for the LeoVegas and Push Gaming acquisitions have not been included because they are not material to the consolidated results of operations. Three Months Ended Nine Months Ended 2022 2022 (In thousands) Net revenues $ 3,416,072 $ 9,958,088 Net income attributable to MGM Resorts International (576,830) 1,203,246 VICI Transaction. Prior to the closing of the VICI Transaction (defined below), MGM Growth Properties LLC (“MGP”) was a consolidated subsidiary of the Company. Substantially all of its assets were owned by and substantially all of its operations were conducted through MGM Growth Properties Operating Partnership LP ("MGP OP”). MGP had two classes of common shares: Class A shares and a single Class B share. The Company owned MGP’s Class B share, through which it held a controlling interest in MGP as it was entitled to an amount of votes representing a majority of the total voting power of MGP’s shares. The Company and MGP each held MGP OP units representing limited partner interests in MGP OP. Additionally, the Company had leased the real estate assets of The Mirage, Luxor, New York-New York, Park MGM, Excalibur, The Park, Gold Strike Tunica, MGM Grand Detroit, Beau Rivage, Borgata, Empire City, MGM National Harbor, MGM Northfield Park, and MGM Springfield from MGP OP. The Company also leased, and continues to lease, the real estate assets of Mandalay Bay and MGM Grand Las Vegas from subsidiaries of a venture that was 50.1% owned by a subsidiary of MGP OP at the time of the transaction (such venture, the “MGP BREIT Venture”). On April 29, 2022, VICI Properties Inc. (“VICI”) acquired MGP in a stock-for-stock transaction (such transaction, the “VICI Transaction”). MGP Class A shareholders received 1.366 shares of newly issued VICI stock in exchange for each MGP Class A share outstanding and the Company received 1.366 units of VICI OP in exchange for each MGP OP unit held by the Company. The fixed exchange ratio represents an agreed upon price of $43 per share of MGP Class A share to the five-day volume weighted average price of VICI stock as of the close of business on July 30, 2021. In connection with the exchange, VICI OP redeemed the majority of the Company’s VICI OP units for cash consideration of $4.4 billion, with the Company retaining an approximate 1% ownership interest in VICI OP that had a fair value of approximately $375 million. MGP’s Class B share that was held by the Company was cancelled. Accordingly, the Company no longer held a controlling interest in MGP and deconsolidated MGP upon the closing of the transactions. Further, the Company entered into an amended and restated master lease with VICI as discussed in Note 8. The Mandalay Bay and MGM Grand Las Vegas lease remained unchanged. In connection with the transactions, the Company recognized a $2.3 billion gain recorded within “Gain on REIT transactions, net.” The gain reflects the fair value of consideration received of $4.8 billion plus the carrying amount of noncontrolling interest immediately prior to the transactions of $3.2 billion less the net carrying value of the assets and liabilities and accumulated comprehensive income derecognized of $5.7 billion. The major classes of assets and liabilities derecognized were as follows: (In thousands) Cash and cash equivalents $ 25,387 Income tax receivable 5,486 Prepaid expenses and other 128 Property and equipment, net 9,250,519 Investments in and advances to unconsolidated affiliates 817,901 Operating lease right-of-use assets, net 236,255 Other long-term assets, net 3,991 Total assets $ 10,339,667 Accounts payable $ 1,136 Accrued interest on long-term debt 68,150 Other accrued liabilities 4,057 Deferred income taxes, net 1,284 Long-term debt, net 4,259,473 Operating lease liabilities 336,689 Total liabilities $ 4,670,789 The Mirage transaction. On December 19, 2022, the Company completed the sale of the operations of The Mirage to an affiliate of Seminole Hard Rock Entertainment, Inc. (“Hard Rock”) for cash consideration of $1.075 billion, or $1.1 billion, net of purchase price adjustments and transaction costs. At closing, the master lease between the Company and VICI was amended to remove The Mirage and to reflect a $90 million reduction in annual cash rent. Gold Strike Tunica. On February 15, 2023, the Company completed the sale of the operations of Gold Strike Tunica to CNE Gaming Holdings, LLC (“CNE”), a subsidiary of Cherokee Nation Business, for cash consideration of $450 million, or $474 million, net of purchase price adjustments and transaction costs. At closing, the master lease between the Company and VICI was amended to remove Gold Strike Tunica and to reflect a $40 million reduction in annual cash rent. The Company recognized a $399 million gain recorded within “Property transactions, net.” The gain reflects the net cash consideration less the net carrying value of the assets and liabilities derecognized of $75 million. The operations of Gold Strike Tunica are not classified as discontinued operations because the Company concluded that the sale is not a strategic shift that has a major effect on the Company’s operations or its financial results and it does not represent a major geographic segment or product line. The major classes of assets and liabilities derecognized are as follows: (In thousands) Cash and cash equivalents $ 26,911 Accounts receivable, net 2,466 Inventories 1,087 Prepaid expenses and other 1,522 Property and equipment, net 21,300 Goodwill 40,523 Other intangible assets, net 5,700 Operating lease right-of-use assets, net 507,231 Other long-term assets, net 1,251 Total assets $ 607,991 Accounts payable $ 1,657 Other accrued liabilities 13,778 Other long-term obligations 1,707 Operating lease liabilities 516,136 Total liabilities $ 533,278

For a limited number of customers, Social Security numbers and passport numbers were also obtained by the criminal actors. The Company has been and continues to notify individuals impacted by this issue in accordance with federal and state law. In connection with this cybersecurity issue, the Company became subject to consumer class actions, to which it will respond in due course. However, the Company cannot predict the timing or outcome of any of these potential matters, or whether the Company may be subject to additional legal proceedings, claims, regulatory inquiries, investigations, or enforcement actions. While the Company believes it is reasonably possible that it may incur losses associated with the above-described proceedings, it is not possible to estimate the amount of loss or range of loss, if any, that might result from adverse judgments, settlements, or other resolution given the preliminary stage of these proceedings. The Company has incurred, and expects to continue to incur, certain expenses related to the cybersecurity issue, including expenses to respond to, remediate, and investigate this matter. The full scope of the costs and related impacts of this issue, including the extent to which all of the costs will be offset by cybersecurity insurance, has not been determined. Other litigation.

Segment Reporting [Abstract]
SEGMENT INFORMATION	SEGMENT INFORMATION The Company’s management views each of its casino properties as an operating segment. Operating segments are aggregated based on their similar economic characteristics, types of customers, types of services and products provided, the regulatory environments in which they operate and their management and reporting structure. The Company has aggregated its operating segments into the following reportable segments: Las Vegas Strip Resorts, Regional Operations and MGM China. Las Vegas Strip Resorts. Las Vegas Strip Resorts consists of the following casino resorts in Las Vegas, Nevada: Aria (including Vdara), Bellagio, The Cosmopolitan (upon its acquisition in May 2022), MGM Grand Las Vegas (including The Signature), Mandalay Bay (including Delano and Four Seasons), The Mirage (until its disposition in December 2022), Luxor, New York-New York (including The Park), Excalibur, and Park MGM (including NoMad Las Vegas). Regional Operations. Regional Operations consists of the following casino properties: MGM Grand Detroit in Detroit, Michigan; Beau Rivage in Biloxi, Mississippi; Gold Strike Tunica in Tunica, Mississippi (until its disposition in February 2023); Borgata in Atlantic City, New Jersey; MGM National Harbor in Prince George’s County, Maryland; MGM Springfield in Springfield, Massachusetts; Empire City in Yonkers, New York; and MGM Northfield Park in Northfield Park, Ohio. MGM China. MGM China consists of MGM Macau and MGM Cotai. The Company’s operations related to LeoVegas (upon its acquisition in September 2022), investments in unconsolidated affiliates, and certain other corporate operations and management services have not been identified as separate reportable segments; therefore, these operations are included in “Corporate and other” in the following segment disclosures to reconcile to consolidated results. Adjusted Property EBITDAR is the Company’s reportable segment GAAP measure, which management utilizes as the primary profit measure for its reportable segments and underlying operating segments. Adjusted Property EBITDAR is a measure defined as earnings before interest and other non-operating income (expense), taxes, depreciation and amortization, preopening and start-up expenses, property transactions, net, gain on REIT transactions, net, rent expense related to triple-net operating leases and ground leases, income from unconsolidated affiliates related to investments in real estate ventures, and also excludes corporate expense and stock compensation expense, which are not allocated to each operating segment, and rent expense related to the master lease with MGP that eliminated in consolidation.

Related Party Transactions [Abstract]
RELATED PARTY TRANSACTIONS	RELATED PARTY TRANSACTIONS MGP. Prior to the closing of the VICI Transaction, the Company leased the real estate assets of The Mirage, Luxor, New York-New York, Park MGM, Excalibur, The Park, Gold Strike Tunica, MGM Grand Detroit, Beau Rivage, Borgata, Empire City, MGM National Harbor, MGM Northfield Park, and MGM Springfield pursuant to a master lease with MGP. The annual cash rent payments under the master lease with MGP for the seventh lease year, which commenced on April 1, 2022, increased to $877 million from $873 million, due to the sixth 2% annual base rent escalator that went into effect on April 1, 2022, as the adjusted net revenue to rent ratio on which such escalator was contingent was met, which increased annual cash rent by $16 million, partially offset by the percentage rent reset that went into effect on April 1, 2022, calculated based on the percentage of average actual annual net revenue of the leased properties during the preceding five year period, which decreased annual cash rent by $12 million. All intercompany transactions, including transactions under the MGP master lease, have been eliminated in the Company’s consolidation of MGP. The public ownership of MGP’s Class A shares was recognized as noncontrolling interests in the Company’s consolidated financial statements. In April 2022, the Company completed the VICI Transaction, which resulted in the deconsolidation of MGP. Refer to Note 3 for additional information on the VICI Transaction. As part of the transaction, the Company entered into an amended and restated master lease with VICI. Refer to Note 8 for further discussion on the master lease with VICI.

BASIS OF PRESENTATION AND SIGNIFICANT ACCOUNTING POLICIES (Policies)	9 Months Ended
	Sep. 30, 2023
Accounting Policies [Abstract]
Basis of presentation	Basis of presentation . As permitted by the rules and regulations of the Securities and Exchange Commission (“SEC”), certain information and footnote disclosures normally included in financial statements prepared in accordance with U.S. generally accepted accounting principles (“U.S. GAAP”) have been condensed or omitted. These consolidated financial statements should be read in conjunction with the Company’s 2022 annual consolidated financial statements and notes thereto included in the Company’s Annual Report on Form 10-K for the year ended December 31, 2022.
Principles of consolidation	Principles of consolidation . The Company evaluates entities for which control is achieved through means other than voting rights to determine if it is the primary beneficiary of a variable interest entity (“VIE”). The Company consolidates its investment in a VIE when it determines that it is its primary beneficiary. The Company may change its original assessment of a VIE upon subsequent events such as the modification of contractual arrangements that affect the characteristics or adequacy of the entity’s equity investments at risk and the disposition of all or a portion of an interest held by the primary beneficiary. The Company performs this analysis on an ongoing basis. The Company has a 5% ownership interest in the venture that owns and leases back the real estate assets of Bellagio (the “Bellagio BREIT Venture”). Bellagio BREIT Venture is a VIE of which the Company is not the primary beneficiary and, accordingly, the Company does not consolidate the venture. The Company’s maximum exposure to loss in Bellagio BREIT Venture is equal to the carrying value of its investment of $55 million as of September 30, 2023, assuming no future capital funding requirements, plus the exposure to loss resulting from the Company’s guarantee of the debt of Bellagio BREIT Venture, which guarantee is immaterial as of September 30, 2023, as further discussed in Note 9. For entities determined not to be a VIE, the Company consolidates such entities in which the Company owns 100% of the equity. For entities in which the Company owns less than 100% of the equity interest, the Company consolidates the entity under the voting interest model if it has a controlling financial interest based upon the terms of the respective entities’ ownership agreements, such as MGM China. For these entities, the Company records a noncontrolling interest in the consolidated balance sheets and all intercompany balances and transactions are eliminated in consolidation. If the entity does not qualify for consolidation under the voting interest model and the Company has significant influence over the operating and financial decisions of the entity, the Company generally accounts for the entity under the equity method, such as BetMGM, which does not qualify for consolidation as the Company has joint control, given the entity is structured with substantive participating rights whereby both owners participate in the decision making process, which prevents the Company from exerting a controlling financial interest in such entity, as defined in Accounting Standards Codification (“ASC”) 810. For entities over which the Company does not have significant influence, the Company accounts for its equity investment under ASC 321.
Fair value measurements	Fair value measurements . Fair value measurements affect the Company’s accounting and impairment assessments of its long-lived assets, investments in unconsolidated affiliates or equity interests, assets acquired, and liabilities assumed in an acquisition, and goodwill and other intangible assets. Fair value measurements also affect the Company’s accounting for certain of its financial assets and liabilities. Fair value is defined as the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date and is measured according to a hierarchy that includes: Level 1 inputs, such as quoted prices in an active market; Level 2 inputs, which are quoted prices for identical or comparable instruments or pricing using observable market data; or Level 3 inputs, which are unobservable inputs. The Company used the following inputs in its fair value measurements: • Level 1 inputs when measuring its equity investments recorded at fair value; • Level 2 inputs for its long-term debt fair value disclosures; See Note 6; • Level 1 and Level 2 inputs for its debt investments; and • Level 1, Level 2, and Level 3 inputs when assessing the fair value of assets acquired and liabilities assumed in acquisitions. See Note 3. Equity investments. Fair value is measured based upon trading prices on the applicable securities exchange for equity investments for which the Company has elected the fair value option of ASC 825 and equity investments accounted for under ASC 321 that have a readily determinable fair value. The fair value of these investments was $409 million and $461 million as of September 30, 2023 and December 31, 2022, respectively, and is reflected within “Other long-term assets, net” on the consolidated balance sheets. Gains and losses are recorded in “Other, net” in the statements of operations. For the three and nine months ended September 30, 2023, the Company recorded a net loss on its equity investments of $57 million and $52 million, respectively. For the three and nine months ended September 30, 2022, the Company recorded a net loss on its equity investments of $20 million and $28 million, respectively. Debt investments. The Company’s investments in debt securities are classified as trading securities and recorded at fair value. Gains and losses are recorded in “Other, net” in the statements of operations. Debt securities are considered cash
Cash and cash equivalents	Cash and cash equivalents. Cash and cash equivalents consist of cash and highly liquid investments with maturities of 90 days or less at the date of purchase. The fair value of cash and cash equivalents approximates carrying value because of the short maturity of those instruments (Level 1).
Restricted cash	Restricted cash. MGM China’s pledged cash of $87 million and $124 million as of September 30, 2023 and December 31, 2022, respectively, securing the bank guarantees discussed in Note 9 is restricted in use and classified within “Other long-term assets, net.” Such amounts plus “Cash and cash equivalents” on the consolidated balance sheets equal “Cash, cash equivalents, and restricted cash” on the consolidated statements of cash flows as of September 30, 2023 and December 31, 2022.
Note receivable	Note receivable. In February 2023, the secured note receivable related to the sale of Circus Circus Las Vegas and the adjacent land was repaid, prior to maturity, for $170 million, which approximated its carrying value on the date of repayment. As of December 31, 2022, the carrying value of the note receivable was $167 million and was recorded within “Other long-term assets, net” on the consolidated balance sheets.
Revenue recognition	Revenue recognition. Contract and Contract-Related Liabilities . There may be a difference between the timing of cash receipts from the customer and the recognition of revenue, resulting in a contract or contract-related liability. The Company generally has three types of liabilities related to contracts with customers: (1) outstanding chip liability, which represents the amounts owed in exchange for gaming chips held by a customer, (2) loyalty program obligations, which represents the deferred allocation of revenue relating to loyalty program incentives earned, and (3) customer advances and other, which is primarily funds deposited by customers before gaming play occurs (“casino front money”) and advance payments on goods and services yet to be provided, such as advance ticket sales and deposits on rooms and convention space or for unpaid wagers. These liabilities are generally expected to be recognized as revenue within one year of being purchased, earned, or deposited and are recorded within “Other accrued liabilities” on the consolidated balance sheets. The following table summarizes the activity related to contract and contract-related liabilities: Outstanding Chip Liability Loyalty Program Customer Advances and Other 2023 2022 2023 2022 2023 2022 (In thousands) Balance at January 1 $ 185,669 $ 176,219 $ 183,602 $ 144,465 $ 816,376 $ 640,001 Balance at September 30 185,615 156,560 204,333 175,716 847,572 747,505 Increase / (decrease) $ (54) $ (19,659) $ 20,731 $ 31,251 $ 31,196 $ 107,504 The January 1, 2023 balances exclude liabilities related to assets held for sale. Revenue by source. The Company presents the revenue earned disaggregated by the type or nature of the good or service (casino, room, food and beverage, and entertainment, retail and other) and by relevant geographic region within Note 12.
Leases	Leases. The Company determines if an arrangement is or contains a lease at inception or modification of the arrangement. An arrangement is or contains a lease if there are identified assets and the right to control the use of an identified asset is conveyed for a period of time in exchange for consideration. Control over the use of the identified asset means the lessee has both the right to obtain substantially all of the economic benefits from the use of the asset and the right to direct the use of the asset. The Company classifies a lease with terms greater than twelve months as either operating or finance. At commencement, the right-of-use (“ROU”) assets and lease liabilities are recognized based on the present value of the future minimum lease payments over the lease term. The initial measurement of ROU assets also includes any prepaid lease payments and are reduced by any previously accrued deferred rent. When available, such as for the Company’s triple-net operating leases for which the lessor has provided its implicit rate or provided the assumptions required for the Company to readily determine the rate implicit in the lease, the Company uses the rate implicit in the lease to discount lease payments to present value. However, for most of the Company’s leases, such as its ground subleases and equipment leases, the Company cannot readily determine the implicit rate. Accordingly, the Company uses its incremental borrowing rate to discount the lease payments for such leases based on the information available at the commencement date. Lease terms include options to extend or terminate the lease when it is reasonably certain that such option will be exercised. The Company’s triple-net operating leases each contain renewal periods at the Company’s option, each of which are not considered to be reasonably certain of being exercised. Many of the Company’s leases include fixed rental escalation clauses that are factored into the determination of lease payments. For operating leases, lease expense for minimum lease payments is recognized on a straight-line basis over the expected lease term. For finance leases, the ROU asset depreciates on a straight-line basis over the shorter of the lease term or useful life of the ROU asset and the lease liability accretes interest based on the interest method using the discount rate determined at lease commencement. Refer to Note 8 for discussion of leases under which the Company is a lessee. The Company is a lessor under certain other lease arrangements. Lease revenues earned by the Company from third parties are classified within the line item corresponding to the type or nature of the tenant’s good or service . For the three and nine months ended September 30, 2023, lease revenues from third-party tenants include $20 million and $57 million recorded within food and beverage revenue, respectively, and $27 million and $86 million recorded within entertainment, retail, and other revenue for the same such periods, respectively. For the three and nine months ended September 30, 2022, lease revenues from third-party tenants include $19 million and $52 million recorded within food and beverage revenue, respectively, and $30 million and $85 million recorded within entertainment, retail, and other revenue for the same such periods, respectively. Lease revenues from the rental of hotel rooms are recorded as rooms revenues within the consolidated statements of operations.
Redeemable noncontrolling interest	Redeemable noncontrolling interest. Noncontrolling interests with redemption features, such as put rights, that are not exclusively in the Company’s control, are considered redeemable noncontrolling interests. Redeemable noncontrolling interests are presented outside of stockholders’ equity within the mezzanine section of the accompanying consolidated balance sheets. The interests are initially accounted for at fair value and subsequently adjusted to the greater of the redemption value and carrying value (initial fair value adjusted for attributed net income (loss) and distributions, as applicable). The Company records such adjustments to capital in excess of par value. During the nine months ended September 30, 2023 and 2022, the Company purchased $138 million and $21 million
Share repurchases	Share repurchases. Shares repurchased pursuant to the Company’s share repurchase plans are retired upon purchase. The cost of the repurchases in excess of the aggregate par value of the shares reduces capital in excess of par value, to the extent available, with any residual cost applied against retained earnings.
