As of June 30, 2022, the Company operates the following integrated casino, hotel and entertainment resorts in Las Vegas, Nevada: Aria (including Vdara), Bellagio, The Cosmopolitan of Las Vegas ( “ The Cosmopolitan”), MGM Grand Las Vegas (including The Signature), The Mirage, Mandalay Bay, Luxor, New York-New York, Park MGM, and Excalibur. The Company also operates MGM Grand Detroit in Detroit, Michigan, MGM National Harbor in Prince George’s County, Maryland, MGM Springfield in Springfield, Massachusetts, Borgata in Atlantic City, New Jersey, Empire City in Yonkers, New York, MGM Northfield Park in Northfield Park, Ohio, and the following resorts in Mississippi: Beau Rivage in Biloxi and Gold Strike Tunica in Tunica. Additionally, the Company operates The Park, a dining and entertainment district located between New York-New York and Park MGM, and the Company owns and operates Shadow Creek, an exclusive world-class golf course located approximately ten miles north of the Las Vegas Strip, and Fallen Oak golf course in Saucier, Mississippi. The Company leases the real estate assets of its domestic resorts pursuant to triple-net lease agreements, as further discussed in Note 9. The Company has an approximate 56% controlling interest in MGM China Holdings Limited (together with its subsidiaries, “MGM China”), which owns MGM Grand Paradise, S.A. (“MGM Grand Paradise”). MGM Grand Paradise owns and operates MGM Macau and MGM Cotai, two integrated casino, hotel and entertainment resorts in Macau, as well as the related gaming subconcession and land concessions. 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 (the “Operating Partnership”). 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 Operating Partnership units representing limited partner interests in the Operating Partnership. Immediately prior to the VICI Transaction, the Company owned 41.5% of the Operating Partnership units, and MGP held the remaining 58.5% ownership interest in the Operating Partnership. Additionally, the Company had leased the real estate assets of certain of its domestic properties from the Operating Partnership, as further discussed in Note 14, and the real estate assets of Mandalay Bay and MGM Grand Las Vegas from a venture that was 50.1% owned by a subsidiary of the Operating Partnership and 49.9% by a subsidiary of Blackstone Real Estate Investment Trust, Inc. (“BREIT”, such venture, the “VICI BREIT Venture”). VICI Transaction. On April 29, 2022, the Company completed a series of transactions with VICI Properties, Inc. (“VICI”) and MGP whereby VICI acquired MGP in a stock-for-stock transaction (such transaction, the “VICI Transaction”), with the Company retaining an approximate 1% ownership interest in VICI Properties OP LLC (“VICI OP”). MGP’s Class B share that was held by the Company was cancelled. Accordingly, the Company no longer holds a controlling interest in MGP and deconsolidated MGP upon the closing of the transactions. Refer to Note 3 for further discussion of the transactions. In connection with the VICI Transaction, the Company entered into an amended and restated master lease with VICI. Refer to Note 9 for further discussion of the lease. The Cosmopolitan acquisition. On May 17, 2022, the Company acquired the operations of The Cosmopolitan. Additionally, the Company entered into a lease agreement for the real estate assets of The Cosmopolitan. Refer to Note 3 for additional information on this acquisition and Note 9 for further discussion of the lease. The Mirage transaction. On December 13, 2021, the Company entered into an agreement to sell the operations of The Mirage to an affiliate of Seminole Hard Rock Entertainment, Inc. ( “ Hard Rock”). Upon closing, the master lease between the Company and VICI will be amended and restated. Refer to Note 3 for additional information on this disposition. LeoVegas transaction. On May 2, 2022, the Company commenced a public offer to the shareholders of LeoVegas AB (publ) (“LeoVegas”) to tender 100% of the shares of LeoVegas at a price of SEK 61 in cash per share, equivalent to a total tender offer value of approximately SEK 6.0 billion (approximately $583 million, based on exchange rates at June 30, 2022). The transaction is expected to close in the third quarter of 2022, subject to certain regulatory approvals, the receipt of valid tenders of more than 90% of LeoVegas’ shares, and customary closing conditions. During the three months ended June 30, 2022, the Company purchased shares of LeoVegas in the open market and, as of June 30, 2022, has a 23% ownership interest. Gold Strike Tunica transaction. On June 9, 2022, the Company entered into an agreement to sell the operations of Gold Strike Tunica to Cherokee Nation Entertainment Gaming Holdings, LLC (“CNE”), a subsidiary of Cherokee Nation Business. Upon closing, the master lease between the Company and VICI will be amended and restated. Refer to Note 3 for additional information on this disposition. MGM Grand Paradise existing gaming subconcession and new gaming law. Gaming in Macau is currently administered by the Macau Government through concessions awarded to three different concessionaires and three subconcessionaires. Pursuant to the agreement dated April 19, 2005 between MGM Grand Paradise and SJM Resorts S.A. ("SJMSA," formerly Sociedade de Jogos de Macau, S.A.), a gaming subconcession was acquired by MGM Grand Paradise for the right to operate casino games of chance and other casino games for a period commencing on April 20, 2005 through March 31, 2020. Pursuant to the then-existing Macau gaming law, upon reaching the maximum duration foreseen in the law (up to a maximum term of 20 years), the term of the concessions may be extended one or more times by order of the Chief Executive, which period may not exceed, in total, 5 years. In 2019, MGM Grand Paradise’s subconcession term was extended from March 31, 2020 to June 26, 2022, consistent with the expiration of the other concessionaires and subconcessionaires. On June 23, 2022, MGM Grand Paradise entered into an addendum to its subconcession pursuant to which its gaming subconcession was extended to December 31, 2022 (refer to Note 6 for additional considerations relating to the gaming subconcession). In connection with the extension, MGM Grand Paradise paid the Macau government MOP 47 million (approximately $6 million) and will provide, within three months of the execution of the extension, a bank guarantee to secure the fulfillment of MGM Grand Paradise’s existing commitment of labor liabilities upon expiration of its subconcession (refer to Note 10 for discussion on the guarantee). Additionally, MGM Grand Paradise executed an agreement with the Macau government pursuant to which the casino areas of MGM Cotai and MGM Macau will be reverted, free of charge and without any encumbrances, to the Macau government at the end of the extended subconcession period on December 31, 2022. Management anticipates the gaming assets subject to reversion will be assets used in gaming operations or located in a gaming area, as well as an allocation of square footage for building assets. Upon reversion, MGM Grand Paradise will cease to have the legal ownership of the gaming assets, and, while management is currently evaluating the effect of the reversion, it expects that it will retain use of such assets if it is able to obtain a gaming concession in the forthcoming public tender. On January 14, 2022, the Macau government disclosed the content of a proposed bill to amend Macau gaming law, which followed a 45-day public consultation process regarding draft amendment proposals that were issued in September 2021. The new gaming law was approved by the Macau Legislative Assembly on June 21, 2022 and published in the Macau Official Gazette on June 22, 2022. Under the new gaming law, the existing subconcessions will be discontinued and a maximum of six concessions will be awarded for a term to be specified in the concession contract that may not exceed 10 years and which may be extended by three years under certain exceptional circumstances. The enactment of the new gaming law precedes the public tender for the awarding of new gaming concessions for which the rules of the public tender were published on July 1, 2022, which outlined the details for the bidding, the qualifications of bidding companies, and the criteria for granting the new gaming concessions. On July 28, 2022, the opening of the public tender was announced with a deadline for the submission of bids of September 14, 2022. MGM China intends to respond proactively and believes it will be in a position to satisfy the relevant requirements relating to the tender process. Certain events relating to the loss, termination, rescission, revocation or modification of MGM Grand Paradise’s ability to game in Macau, where such events have a material adverse effect on the financial condition, business, properties, or results of operations of MGM China, taken as a whole, may result in a special put option triggering event under MGM China’s senior notes and in an event of default under MGM China’s revolving credit facilities. Management cannot provide any assurance that it will be able to obtain a gaming concession in the public tender; however, management believes that MGM Grand Paradise will be successful in obtaining a gaming concession when the public tender is held. BetMGM. The Company owns 50% of BetMGM, LLC (“BetMGM”), which provides online sports betting and iGaming in certain jurisdictions in North America. The other 50% of BetMGM is owned by Entain plc. Reportable segments. The Company has three reportable segments: Las Vegas Strip Resorts, Regional Operations and MGM China. See Note 13 for additional information about the Company’s segments. Impact of COVID-19 - Update. As of June 30, 2022, all of the Company’s domestic properties were open and not subject to operating restrictions; however, travel and business volume were negatively affected in the early part of the first quarter of 2022 due to the spread of the omicron variant. Macau is currently operating under a “dynamic zero” COVID-19 policy, as is Hong Kong and mainland China. The Company’s properties in Macau were open during the first half of 2022, however, gaming operations were temporarily suspended on July 11, 2022 due to an increase in the number of COVID-19 cases in Macau and resumed on July 23, 2022, subject to certain continuing health safeguards, with most restaurants and bars and certain retail outlets remaining closed. Several travel and entry restrictions in Macau, Hong Kong and mainland China remain in place, including entry bans, visa limitations, COVID-19 testing, and certain quarantine requirements, which have significantly impacted visitation to the Company’s Macau properties. Although gaming operations have resumed, protective and operational measures have had a negative effect on MGM China’s operations. The extent and timing of a closure of the MGM China’s properties, limitations of operations, or whether further travel restrictions to or from Macau will be implemented is uncertain if there is an increase or continued spread of COVID-19.

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 2021 annual consolidated financial statements and notes thereto included in the Company’s Annual Report on Form 10-K for the year ended December 31, 2021. 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. Management has determined that the venture that is 5% owned by a subsidiary of the Company and 95% owned by a subsidiary of BREIT, (such venture, the “Bellagio BREIT Venture”), is a VIE because the equity holders as a group lack the power through voting or similar rights to direct the activities of such entity that most significantly impact such entity’s economic performance. The Company has determined that it is not the primary beneficiary of Bellagio BREIT Venture because the Company does not have power to direct the activities that could potentially be significant to the venture as BREIT, as the managing member, has such power; 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 $57 million as of June 30, 2022, 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 June 30, 2022, as further discussed in Note 10. 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 ASC 810. For entities over which the Company does not have significant influence, such as VICI OP, 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 observable inputs for similar assets; 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 1 and Level 2 inputs for its long-term debt fair value disclosures. See Note 7; 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. 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, such as LeoVegas, and equity investments accounted for under ASC 321, such as VICI OP. The fair value of these investments was $571 million and $66 million as of June 30, 2022 and December 31, 2021, respectively, and is reflected within “Other long-term assets, net” on the consolidated balance sheets. Unrealized gains and losses are recorded in “Other, net” in the statements of operations. For the three and six months ended June 30, 2022, the Company recorded a net unrealized loss of $23 million and $8 million, respectively. For each of the three and six months ended June 30, 2021, the Company recorded a net unrealized gain of $86 million. Restricted cash. Restricted cash reflects cash held in an escrow account related to the reverse termination fee that was contractually required to be prefunded for The Cosmopolitan acquisition and is reflected as “Restricted Cash” on the consolidated balance sheets as of December 31, 2021. “Restricted Cash” and “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 December 31, 2021. Accounts receivable. As of June 30, 2022 and December 31, 2021, the loss reserve on accounts receivable was $113 million and $128 million, respectively. 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 2022 2021 2022 2021 2022 2021 (In thousands) Balance at January 1 $ 176,219 $ 212,671 $ 144,465 $ 139,756 $ 640,001 $ 382,287 Balance at June 30 165,564 144,975 160,752 136,659 704,404 513,971 Increase / (decrease) $ (10,655) $ (67,696) $ 16,287 $ (3,097) $ 64,403 $ 131,684 The June 30, 2022 balances exclude liabilities related to assets held for sale. See Note 3. 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 13. 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 date, 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 the operating lease 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 9 for discussion of leases under which the Company is a lessee. Refer to Note 14 for discussion of the master lease with MGP. 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 . During the three and six months ended June 30, 2022, lease revenues from third-party tenants include $19 million and $33 million recorded within food and beverage revenue, respectively, and $29 million and $55 million recorded within entertainment, retail, and other revenue for the same such periods, respectively. During the three and six months ended June 30, 2021, lease revenues from third-party tenants include $11 million and $16 million recorded within food and beverage revenue, respectively, and $20 million and $36 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. Share repurchases. Shares repurchased pursuant to the Company’s share repurchase programs 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 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. As the transaction was recently consummated on May 17, 2022, the allocation of fair value for substantially all of the assets and liabilities is preliminary as of June 30, 2022, and may be adjusted up to one year after the acquisition. The following table sets forth the preliminary purchase price allocation (in thousands): Fair value of assets acquired and liabilities assumed: Cash and cash equivalents $ 80,670 Receivables and other current assets 98,006 Property and equipment 122,419 Trademarks 130,000 Customer lists 95,000 Goodwill 1,284,309 Operating lease right-of-use-assets, net 3,404,894 Other long-term assets 23,709 Accounts payable, accrued liabilities, and other current liabilities (145,350) Operating lease liabilities (3,401,815) Other long-term liabilities (1,570) $ 1,690,272 The estimated fair values of the intangible assets were determined using methodologies under the income approach based on significant inputs that were not observable. The identified 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 Company’s Las Vegas Strip Resorts segment. The operating results for The Cosmopolitan are included in the accompanying consolidated statements of operations from the date of acquisition. The Cosmopolitan’s net revenue for the period from May 17, 2022 through June 30, 2022 was $151 million and operating income and net income were $18 million and $18 million, respectively. CityCenter acquisition. On September 27, 2021, the Company acquired Infinity World’s 50% ownership interest in CityCenter for cash consideration of $2.125 billion. Prior to the acquisition, the Company held a 50% ownership interest, which was accounted for under the equity method. Through the acquisition, the Company obtained 100% of the equity interests and therefore consolidated CityCenter as of September 27, 2021. The fair value of the equity interests of CityCenter was determined by the transaction price and equaled $4.25 billion. On September 28, 2021, the Company sold the real estate assets of Aria (including Vdara) for cash consideration of $3.89 billion and entered into a lease agreement pursuant to which the Company leases back the real property. The Company classified the real estate assets as held for sale as of the acquisition date and accordingly measured the real estate assets at fair value less costs to sell, as reflected in the table below. See Note 9 for discussion of the lease. The Company recognized 100% of the assets and liabilities of CityCenter 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 following table sets forth the purchase price allocation (in thousands): Fair value of assets acquired and liabilities assumed: Cash and cash equivalents $ 335,396 Receivables and other current assets 106,417 Property and equipment - real estate assets held for sale 3,888,431 Property and equipment 323,093 Trademarks 180,000 Goodwill 1,397,338 Other long-term assets 13,923 Accounts payable, accrued liabilities, and other current liabilities (201,093) Debt (1,729,451) Other long-term liabilities (64,054) $ 4,250,000 The fair value of the acquired indefinite-lived trademarks was determined using methodologies under the relief from royalty method based on significant inputs that were not observable. The goodwill is primarily attributable to the profitability of CityCenter in excess of identifiable assets, of which approximately 50% of the goodwill is deductible for income tax purposes. All of the goodwill was assigned to the Company’s Las Vegas Strip Resorts segment. Unaudited pro forma information - CityCenter and The Cosmopolitan acquisitions . The following unaudited pro forma consolidated financial information for the Company has been prepared assuming the Company’s acquisition of its controlling interest of CityCenter had occurred as of January 1, 2020 and the acquisition of The Cosmopolitan had occurred as of January 1, 2021. The pro forma information excludes the gain on consolidation of CityCenter and does not reflect transactions that occurred subsequent to acquisition, such as the Aria real estate sale-leaseback transaction or the repayment of CityCenter’s assumed debt. 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. Three Months Ended Six Months Ended 2022 2021 2022 2021 (In thousands) Net revenues $ 3,422,277 $ 2,685,073 $ 6,542,015 $ 4,554,236 Net income (loss) attributable to MGM Resorts International 1,781,930 167,176 1,780,076 (188,776) VICI Transaction. On April 29, 2022, VICI acquired MGP in a stock-for-stock 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 Operating Partnership 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 holds 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 9. The lease between the Company and VICI BREIT Venture for the real estate assets of Mandalay Bay and MGM Grand Las Vegas 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 carrying value of the assets and liabilities and accumulated comprehensive income derecognized of $5.7 billion. The major classes of assets and liabilities derecognized are 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. On December 13, 2021, the Company entered into an agreement to sell the operations of The Mirage to an affiliate of Hard Rock for cash consideration of $1.075 billion, subject to certain purchase price adjustments. Upon closing, the master lease between the Company and VICI will be amended and restated to reflect a $90 million reduction in annual cash rent. The transaction is expected to close during the fourth quarter of 2022, subject to certain closing conditions, including, but not limited to, the receipt of regulatory approvals. The closing condition that the VICI Transaction is consummated or terminated was resolved upon the closing of such transaction and, accordingly, the asset group is classified as held for sale as of June 30, 2022. Gold Strike Tunica. On June 9, 2022, the Company entered into an agreement to sell the operations of Gold Strike Tunica to CNE for cash consideration of $450 million, subject to certain purchase price adjustments. Upon closing, the master lease between the Company and VICI will be amended and restated to reflect a $40 million reduction in annual cash rent. The transaction is expected to close during the first quarter of 2023, subject to certain closing conditions, including, but not limited to, the receipt of regulatory approvals.

As described in Note 1, the enactment of the new Macau gaming law in June 2022 provides for material changes to the legal form of gaming concessions in Macau, including discontinuing and prohibiting gaming subconcessions subsequent to their expiration, and also includes material changes to the rights and obligations provided for under the new gaming concessions to be awarded in the upcoming public tender. As a result, the Company determined that the existing MGM Grand Paradise gaming subconcession and new gaming concession, if obtained, would be two separate units of account. Further, as the material changes in the legal and regulatory environment could have an adverse effect on the value of MGM Grand Paradise’s gaming subconcession, the Company concluded that a triggering event had occurred under ASC 360 in June 2022 for the MGM China asset group. The Company compared the estimated undiscounted cash flows of the asset group to its carrying value and determined that the undiscounted cash flows significantly exceeded the carrying value and therefore, no impairment was indicated. Additionally, the Company reassessed the useful life of the existing gaming subconcession intangible asset and determined that, given the new gaming law and the resulting changes described above, the useful life would no longer be based on the initial term of the MGM Cotai land concession, which ends in January 2038, and that the useful life should be revised to align with the cessation of the subconcession rights that will occur at the end of the contractual term of the existing gaming subconcession, which ends on December 31, 2022. Accordingly, amortization of the MGM Grand Paradise gaming subconcession will be recognized on a straight-line basis over its reduced useful life.

Under the stock repurchase programs, the Company may repurchase shares from time to time in the open market or in privately negotiated agreements. Repurchases of common stock may also be made under a Rule 10b5-1 plan, which would permit common stock to be repurchased when the Company might otherwise be precluded from doing so under insider trading laws. The timing, volume and nature of stock repurchases will be at the sole discretion of management, dependent on market conditions, applicable securities laws, and other factors, and may be suspended or discontinued at any time. During the three months ended June 30, 2021, the Company repurchased approximately 6 million shares of its common stock at an average price of $39.48 per share for an aggregate amount of $220 million.

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 MGP master lease 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 tenant and operating subsidiary sublessee, collectively, met the adjusted net revenue to rent ratio on which such escalator was contingent, 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, were 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, including its investment in the VICI BREIT Venture. Refer to Note 3 for additional information on the VICI Transaction. As part of the transactions, the Company entered into an amended and restated master lease with VICI. Refer to Note 9 for further discussion on the master lease with VICI. Bellagio BREIT Venture The Company has a 5% ownership interest in Bellagio BREIT Venture, which owns the real estate assets of Bellagio and leases such assets to a subsidiary of the Company pursuant to a lease agreement. Refer to Note 9 for further information related to the Bellagio lease.

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 2021 annual consolidated financial statements and notes thereto included in the Company’s Annual Report on Form 10-K for the year ended December 31, 2021. 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	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. Management has determined that the venture that is 5% owned by a subsidiary of the Company and 95% owned by a subsidiary of BREIT, (such venture, the “Bellagio BREIT Venture”), is a VIE because the equity holders as a group lack the power through voting or similar rights to direct the activities of such entity that most significantly impact such entity’s economic performance. The Company has determined that it is not the primary beneficiary of Bellagio BREIT Venture because the Company does not have power to direct the activities that could potentially be significant to the venture as BREIT, as the managing member, has such power; 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 $57 million as of June 30, 2022, 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 June 30, 2022, as further discussed in Note 10.
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 observable inputs for similar assets; 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 1 and Level 2 inputs for its long-term debt fair value disclosures. See Note 7; 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. 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, such as LeoVegas, and equity investments accounted for under ASC 321, such as VICI OP. The fair value of these investments was $571 million and $66 million as of June 30, 2022 and December 31, 2021, respectively, and is reflected within “Other long-term assets, net” on the consolidated balance sheets. Unrealized gains and losses are recorded in “Other, net” in the statements of operations. For the three and six months ended June 30, 2022, the Company recorded a net unrealized loss of $23 million and $8 million, respectively. For each of the three and six months ended June 30, 2021, the Company recorded a net unrealized gain of $86 million.
Restricted cash	Restricted cash. Restricted cash reflects cash held in an escrow account related to the reverse termination fee that was contractually required to be prefunded for The Cosmopolitan acquisition and is reflected as “Restricted Cash” on the consolidated balance sheets as of December 31, 2021. “Restricted Cash” and “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 December 31, 2021.
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 2022 2021 2022 2021 2022 2021 (In thousands) Balance at January 1 $ 176,219 $ 212,671 $ 144,465 $ 139,756 $ 640,001 $ 382,287 Balance at June 30 165,564 144,975 160,752 136,659 704,404 513,971 Increase / (decrease) $ (10,655) $ (67,696) $ 16,287 $ (3,097) $ 64,403 $ 131,684 The June 30, 2022 balances exclude liabilities related to assets held for sale. See Note 3. 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 13.
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 date, 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 the operating lease 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 9 for discussion of leases under which the Company is a lessee. Refer to Note 14 for discussion of the master lease with MGP. 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 . During the three and six months ended June 30, 2022, lease revenues from third-party tenants include $19 million and $33 million recorded within food and beverage revenue, respectively, and $29 million and $55 million recorded within entertainment, retail, and other revenue for the same such periods, respectively. During the three and six months ended June 30, 2021, lease revenues from third-party tenants include $11 million and $16 million recorded within food and beverage revenue, respectively, and $20 million and $36 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. Share repurchases. Shares repurchased pursuant to the Company’s share repurchase programs 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.
