Organization Consolidation And Presentation Of Financial Statements [Abstract]
Organization	NOTE 1 — ORGANIZATION Organization. MGM Resorts International (together with its consolidated subsidiaries, unless otherwise indicated or unless the context requires otherwise, the “Company”) is a Delaware corporation that acts largely as a holding company and, through subsidiaries, owns and operates casino resorts. The Company owns and operates the following integrated casino, hotel and entertainment resorts in Las Vegas, Nevada: Bellagio, MGM Grand Las Vegas, The Mirage, Mandalay Bay, Luxor, New York-New York, Park MGM, Excalibur and Circus Circus Las Vegas. Operations at MGM Grand Las Vegas include management of The Signature at MGM Grand Las Vegas, a condominium-hotel consisting of three towers. The Company operates and, along with local investors, owns MGM Grand Detroit in Detroit, Michigan, MGM National Harbor in Prince George’s County, Maryland, and MGM Springfield in Springfield, Massachusetts. The Company also owns and operates Borgata located on Renaissance Pointe in the Marina area of 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 in Tunica. Additionally, the Company owns The Park, a dining and entertainment district located between New York-New York and Park MGM, Shadow Creek, an exclusive world-class golf course located approximately ten miles north of its Las Vegas Strip resorts, Primm Valley Golf Club at the California/Nevada state line and Fallen Oak golf course in Saucier, Mississippi. MGM Growth Properties LLC (“MGP”), a consolidated subsidiary of the Company, is organized as an umbrella partnership REIT (commonly referred to as an UPREIT) structure in which substantially all of its assets are owned by and substantially all of its businesses are conducted through MGM Growth Properties Operating Partnership LP (the “Operating Partnership”). MGP has two classes of authorized and outstanding voting common shares (collectively, the “shares”): Class A shares and a single Class B share. The Company owns MGP’s Class B share, which does not provide its holder any rights to profits or losses or any rights to receive distributions from operations of MGP or upon liquidation or winding up of MGP. MGP’s Class A shareholders are entitled to one vote per share, while the Company, as the owner of the Class B share, is entitled to an amount of votes representing a majority of the total voting power of MGP’s shares so long as the Company and its controlled affiliates’ (excluding MGP) aggregate beneficial ownership of the combined economic interests in MGP and the Operating Partnership does not fall below 30%. The Company and MGP each hold Operating Partnership units representing limited partner interests in the Operating Partnership. The general partner of the Operating Partnership is a wholly-owned subsidiary of MGP. The Operating Partnership units held by the Company are exchangeable into Class A shares of MGP on a one-to-one basis, or cash at the fair value of a Class A share. The determination of settlement method is at the option of MGP’s independent conflicts committee. The Company and MGP’s ownership interest percentage in the Operating Partnership have varied based upon the transactions that MGP has completed, as discussed in Note 10. As of June 30, 2019, the Company owned 68.3% of the Operating Partnership units, and MGP held the remaining 31.7% ownership interest in the Operating Partnership. Pursuant to a master lease agreement between a subsidiary of the Company (the “tenant”) and a subsidiary of the Operating Partnership (the “landlord”), the tenant leases the real estate assets of The Mirage, Mandalay Bay, Luxor, New York-New York, Park MGM, Excalibur, The Park, Gold Strike Tunica, MGM Grand Detroit, Beau Rivage, Borgata, Empire City, MGM National Harbor, and MGM Northfield Park from the landlord. In January 2019, the Company acquired the real property and operations associated with the Empire City Casino's race track and casino (“Empire City”). Subsequently, MGP acquired the developed real property associated with Empire City from the Company and Empire City was added to the existing master lease between the Company and MGP. Refer to Note 3 for additional information. In March 2019, the Company entered into an amendment to the existing master lease with respect to investments made by the Company related to improvements at Park MGM and NoMad Las Vegas. Additionally, in April 2019, the Company acquired the membership interests of Northfield Park Associates, LLC (“Northfield”), the entity that owned the operating assets associated with Hard Rock Rocksino Northfield Park (rebranded to MGM Northfield Park upon the Company’s acquisition), from MGP, and MGP retained the associated real estate assets. MGM Northfield Park was then added to the existing master lease between the Company and MGP. Refer to Note 12 for additional information on these transactions. 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 the MGM Macau resort and casino and MGM Cotai, an integrated casino, hotel and entertainment resort located on the Cotai Strip in Macau, as well as the related gaming subconcession and land concessions. In March 2019, MGM Grand Paradise and its concessionaire, Sociedade de Jogos de Macau, S.A (“SJMSA”) entered into a Sub-Concession Extension Contract (the “Extension Agreement”), pursuant to which the gaming sub-concession of MGM Grand Paradise, which was due to expire on March 31, 2020, has been extended to June 26, 2022, which coincides with the current expiration date of all the other concessionaires and sub-concessionaires. The Company owns 50% of and manages CityCenter Holdings, LLC (“CityCenter”), located between Bellagio and Park MGM. The other 50% of CityCenter is owned by Infinity World Development Corp, a wholly owned subsidiary of Dubai World, a Dubai, United Arab Emirates government decree entity. CityCenter consists of Aria, an integrated casino, hotel and entertainment resort; and Vdara, a luxury condominium-hotel. See Note 4 for additional information related to CityCenter. The Company and a subsidiary of Anschutz Entertainment Group, Inc. (“AEG”) each own 42.5% of the Las Vegas Arena Company, LLC (“Las Vegas Arena Company”), the entity which owns the T-Mobile Arena, and Athena Arena, LLC owns the remaining 15%. The Company also manages the T-Mobile Arena. Additionally, the Company leases the MGM Grand Garden Arena, located adjacent to the MGM Grand Las Vegas, to the Las Vegas Arena Company. See Note 4 for additional information regarding the Company’s investment in the Las Vegas Arena Company. The Company has three reportable segments: Las Vegas Strip Resorts, Regional Operations and MGM China. See Note 11 for additional information about the Company’s segments.

Accounting Policies [Abstract]
Basis of Presentation and Significant Accounting Policies	NOTE 2 — 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 2018 annual consolidated financial statements and notes thereto included in the Company’s Annual Report on Form 10-K for the year ended December 31, 2018. 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. Management has determined that MGP is a variable interest entity (“VIE”) because the Class A equity investors 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 the primary beneficiary of MGP and consolidates MGP because (i) its ownership of MGP’s single Class B share entitles it to a majority of the total voting power of MGP’s shares, and (ii) the exchangeable nature of the Operating Partnership units owned provide the Company the right to receive benefits from MGP that could potentially be significant to MGP. The Company has recorded MGP’s ownership interest in the Operating Partnership of 31.7% as of June 30, 2019 as noncontrolling interest in the Company’s consolidated financial statements. As of June 30, 2019 and December 31, 2018, on a consolidated basis, MGP had total assets of $11.9 billion and $11.0 billion, respectively, primarily related to its real estate investments, and total liabilities of $5.5 billion and $5.1 billion, respectively, primarily related to its indebtedness. Reclassifications. Certain reclassifications have been made to conform the prior period presentation. Revenue recognition. The Company’s revenue contracts with customers consist of casino wager transactions, hotel room sales, food and beverage transactions, entertainment shows, and retail transactions. For casino wager transactions that include incentives earned by customers under the Company’s loyalty programs, the Company allocates a portion of net win based upon the standalone selling price of such incentive (less estimated breakage). This allocation is deferred and recognized as revenue when the customer redeems the incentive. When redeemed, revenue is recognized in the department that provides the goods or service. Redemption of loyalty incentives at third party outlets are deducted from the loyalty liability and amounts owed are paid to the third party, with any discount received recorded as other revenue. During the three and six months ended June 30, 2019, commissions and incentives provided to gaming customers were $601 million and $1.2 billion, respectively. During the three and six months ended June 30, 2018, commissions and incentives provided to gaming customers were $520 million and $1.1 billion, respectively. After allocating revenue to other goods and services provided as part of casino wager transactions, the Company records the residual amount to casino revenue. 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, as discussed above, 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 Company’s 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 2019 2018 2019 2018 2019 2018 (in thousands) Balance at January 1 $ 323,811 $ 597,753 $ 113,293 $ 91,119 $ 667,285 $ 539,626 Balance at June 30 322,259 759,049 120,978 98,308 588,559 510,750 Increase / (decrease) $ (1,552 ) $ 161,296 $ 7,685 $ 7,189 $ (78,726 ) $ (28,876 ) 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 11. 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 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. For leases with terms greater than twelve months, the operating lease right-of-use (“ROU”) assets and operating lease liabilities are recognized based on the present value of the future minimum lease payments over the lease term at commencement date. The initial measurement of the operating lease ROU assets also include any prepaid lease payments and are reduced by any previously accrued deferred rent. When available, the Company uses the rate implicit in the lease to discount lease payments to present value; however, most of the Company’s leases do not provide a readily determinable implicit rate. Therefore, the Company uses its incremental borrowing rate to discount the lease payments based on the information available at commencement date. Many of the Company’s leases include fixed rental escalation clauses that are factored into the determination of lease payments. Lease terms include options to extend or terminate the lease when it is reasonably certain that such option will be exercised. Lease expense for minimum lease payments is recognized on a straight-line basis over the expected lease term. The Company is a lessor under certain of its lease arrangements. Lease revenues earned by the Company from third-party tenants 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, 2019, lease revenues from third-party tenants include $13 million and $25 million recorded within food and beverage revenue, respectively, and $22 million and $44 million recorded within entertainment, retail, and other revenue for the same such periods, respectively. During the three and six months ended June 30, 2018, lease revenues from third-party tenants include $12 million and $25 million recorded within food and beverage revenue, respectively, and $22 million and $43 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. Recently issued accounting standards. In February 2016, the FASB issued ASC 842 “Leases (Topic 842)”, which replaces the existing guidance in Topic 840, “Leases”, (“ASC 842”). ASC 842 is effective for fiscal years, and interim periods within those years, beginning after December 15, 2018. ASC 842 requires a dual approach for lessee accounting under which a lessee would classify and account for its lease agreements as either finance or operating. Both finance and operating leases will result in the lessee recognizing a ROU asset and a corresponding lease liability. For finance leases, the lessee will recognize interest expense associated with the lease liability and depreciation expense associated with the ROU asset; and for operating leases, the lessee will recognize straight-line rent expense. The Company adopted ASC 842 on January 1, 2019 utilizing the simplified transition method and accordingly did not recast comparative period financial information. The Company elected the basket of transition practical expedients which includes not needing to reassess: (1) whether any expired or existing contracts are or contain leases, (2) the lease classification for any expired or existing leases, and (3) direct costs for any existing leases. As a result of adoption, the Company recognized $656 million of operating ROU assets and $580 million of operating lease liabilities as of January 1, 2019. Prior to the adoption of ASC 842 on January 1, 2019, the master lease between subsidiaries of MGM and MGP was accounted for as a failed sale of the real estate assets due to the subsidiaries’ investments in the Operating Partnership, which constituted continuing involvement. As such, the real estate assets were reflected in the balance sheets of the applicable MGM subsidiaries as well as the associated finance lease liability. In connection with the adoption of ASC 842, the sale and leaseback of the real estate assets under the master lease now qualify as a passed sale and are determined to be operating leases. Accordingly , the real estate assets are now only reflected on the balance sheet of MGP and the MGM subsidiaries have recorded operating lease liabilities and operating ROU assets. The master lease and its related accounting eliminates in consolidation.

Business Combinations [Abstract]
Acquisitions	NOTE 3 — ACQUISITIONS Empire City On January 29, 2019, the Company acquired the real property and operations associated with Empire City for total consideration of approximately $865 million, plus customary working capital and other adjustments (“Empire City Acquisition”). The fair value of consideration paid included the issuance of approximately $266 million of the Company’s common stock, the incurrence of a new bridge facility, and the remaining balance in cash. If Empire City is awarded a license for live table games on or prior to December 31, 2022 and the Company accepts such license by December 31, 2024, the Company will pay additional consideration of $50 million. The acquisition expands the Company’s presence in the northeast region and greater New York City market. Subsequent to the Company’s acquisition, MGP acquired the developed real property associated with Empire City from the Company and Empire City was added to the existing master lease between the Company and MGP. See Note 12 for additional information. The Company recognized 100% of the assets and liabilities of Empire City at fair value on the date of 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 both level 2 inputs, which are observable inputs for similar assets, and level 3 inputs, which are unobservable inputs. During the quarter ended June 30, 2019, the Company received updated information regarding facts and circumstances in existence as of the acquisition date that impacted the forecasted revenues and expenses utilized in the preliminary purchase price valuation. As a result, the Company recorded a measurement period adjustment that included a $76 million decrease to the racing and gaming license, a $17 million decrease to other intangible assets and a $20 million decrease to deferred income taxes, with the offset to goodwill. The allocation of fair value for the assets and liabilities remains preliminary, specifically for the intangibles, goodwill, and deferred income taxes, and may continue to be adjusted up to one year after the acquisition. Accordingly, final determination of the fair values may result in further adjustments to the values presented in the table below. The following table sets forth the preliminary purchase price allocation (in thousands): Fair value of assets acquired and liabilities assumed: Property and equipment $ 645,733 Cash and cash equivalents 63,197 Racing and gaming license 52,000 Other intangible assets 34,000 Goodwill 256,133 Other assets 24,420 Deferred income taxes (125,149 ) Other liabilities (85,690 ) $ 864,644 The Company recognized the identifiable intangible assets at fair value. The estimated fair values of the intangible assets were preliminarily determined using methodologies under the income approach based on significant inputs that were not observable. The gaming license is an indefinite-lived intangible asset and the customer lists and trade name acquired, both of which comprise other intangible assets above, are amortized over their estimated useful lives of approximately four and five years, respectively. The goodwill is primarily attributable to the potential for a conversion to a full-scale gaming facility. Consolidated results. For the period from January 29, 2019 through June 30, 2019, Empire City’s net revenue was $91 million, operating income was $9 million and net income was $20 million. Pro forma results of operations for the acquisition have not been presented because it is not material to the consolidated results of operations. Northfield On July 6, 2018, MGP completed its acquisition of 100% of the membership interests of Northfield. The financial results of Northfield have been included in the consolidated financial statements from the date of acquisition. In April 2019, the Company subsequently acquired the membership interests of Northfield from MGP, and MGP retained the associated real estate assets. MGM Northfield Park was then added to the existing master lease between the Company and MGP. Refer to Note 12 for additional information on this intercompany transaction which eliminates in consolidation.

Income Tax Disclosure [Abstract]
Income Taxes	NOTE 6 — INCOME TAXES For interim income tax reporting the Company estimates its annual effective tax rate and applies it to its year-to-date ordinary income. The tax effects of unusual or infrequently occurring items, including changes in judgment about valuation allowances and effects of changes in tax laws or rates, are reported in the interim period in which they occur. The Company’s effective income tax rate was a provision of 13.3% and a provision of 36.9% for the three and six months ended June 30, 2019, respectively, compared to a provision of 14.4% and a benefit of 17.9% for the three and six months ended June 30, 2018, respectively. The Company recognizes deferred income tax assets, net of applicable reserves, related to net operating losses, tax credit carryforwards and certain temporary differences. The Company recognizes future tax benefits to the extent that realization of such benefit is more likely than not. Otherwise, a valuation allowance is applied. MGM Grand Paradise was previously granted an exemption from the Macau 12% complementary tax on gaming profits through March 31, 2020 and, given the Extension Agreement entered into last quarter, has applied for an extension of such exemption to June 26, 2022 to run concurrent with its extended sub-concession. Competitors of MGM Grand Paradise have received additional extensions of their complementary tax exemptions through June 26, 2022, which runs concurrent with the end of the term of their gaming concessions. The Company believes MGM Grand Paradise should also be entitled to such extension in order to ensure non-discriminatory treatment among gaming concessionaires and sub-concessionaires, a requirement under Macanese law. $35 million, due to an increase in the valuation allowance on certain net operating loss deferred tax assets partially offset by a reduction in certain intangible deferred tax liabilities, The Company recorded a $10 million increase in its valuation allowance on its foreign tax credit carryovers (“FTCs”) and a corresponding increase in its income tax expense for the six months ended June 30, 2019 based upon a revision of certain assumptions impacting the valuation allowance. The FTCs are attributable to the Macau Special Gaming Tax, which is 35% of gross gaming revenue in Macau. Significant judgment is required in assessing the need for a valuation allowance and future changes to these assumptions could result in material changes in the valuation allowance with a corresponding impact on the provision for income taxes in the period including such change. Further, the Empire City Acquisition required a re-measurement of existing state deferred tax liabilities resulting in a $10 million increase in deferred tax liabilities and a corresponding income tax expense for the six months ended June 30, 2019.

Commitments And Contingencies Disclosure [Abstract]
Commitments and Contingencies	NOTE 8 — COMMITMENTS AND CONTINGENCIES October 1 litigation. The Company and/or certain of its subsidiaries have been named as defendants in a number of lawsuits related to the October 1, 2017 shooting in Las Vegas. The matters involve in large degree the same legal and factual issues, each case being filed on behalf of individuals who are seeking damages for emotional distress, physical injury, medical expenses, economic damages and/or wrongful death. Lawsuits were first filed in October 2017 and include actions originally filed in the District Court of Clark County, Nevada and in the Superior Court of Los Angeles County, California. In June 2018, the Company removed to federal court all actions that remained pending in California and Nevada state courts. The Company also initiated declaratory relief actions in federal courts in various districts against individuals who had sued or stated an intent to sue. Additional lawsuits related to this incident may be filed in the future. Since February of 2019, the Company and counsel representing plaintiffs in all pending matters and purporting to represent substantially all claimants known to the Company (collectively, the “Claimants”) have been, and continue to be, engaged in mediation efforts to resolve these matters. After multiple mediation sessions over several months, progress has been made, and while mediation is ongoing, the Company believes it is reasonably possible that a settlement will be reached. The related litigation is stayed pending mediation (the “Mediation Stay”) and the Company agreed to toll the statute of limitations to May 15, 2020, with respect to the Claimants. Although the Company continues to believe it is not legally responsible for the perpetrator’s criminal acts, in the interest of avoiding protracted litigation and the related impact on the community, the Company believes it is reasonably possible that continued mediation communications will result in a settlement with respect to the Claimants of approximately $735 million, subject to and depending on obtaining a minimum level of participation with escalators based on greater participation increasing the amount payable up to $800 million in the event of 100% participation. The Company has $751 million of insurance coverage available to fund this potential settlement, which the Company’s insurers have agreed to fund. The Company intends for substantially all Claimants to be covered by the settlement, however, it remains possible that certain Claimants may not join the settlement and/or additional claims may be asserted. The foregoing determination was made in accordance with generally accepted accounting principles, as codified in ASC 450-20, and is not an admission of any liability on the part of the Company or any of its affiliates. If such a settlement is not consummated, the Mediation Stay will be lifted and the Company is currently unable to reliably predict the future developments in, outcome of, and economic costs and other consequences of any such litigation related to this matter. The Company will continue to investigate the factual and legal defenses, and evaluate these matters based on subsequent events, new information and future circumstances. The Company intends to defend against any such lawsuits and ultimately believes it should prevail, but litigation of this type is inherently unpredictable. Although there are significant procedural, factual and legal issues to be resolved that could significantly affect the Company’s belief as to the possibility of liability, the Company currently believes that it is reasonably possible that it could incur liability in connection with certain of these lawsuits. The foregoing determination was made in accordance with generally accepted accounting principles, as codified in ASC 450-20, and is not an admission of any liability on the part of the Company or any of its affiliates. Given that these cases would be in the early stages, and in light of the uncertainties surrounding them, the Company does not currently possess sufficient information to determine a range of reasonably possible liability. The insurance carriers have not expressed a reservation of rights or coverage defense that affects the Company’s evaluation of potential losses in connection with these claims. The Company’s general liability insurance coverage provides, as part of the contractual “duty to defend”, payment of legal fees and associated costs incurred to defend covered lawsuits that are filed arising from the October 1, 2017 shooting in Las Vegas. Payment of such fees and costs is in addition to (and not limited by) the limits of the insurance policies and does not erode the total liability coverage available. Other litigation. The Company is a party to various legal proceedings, most of which relate to routine matters incidental to its business. Management does not believe that the outcome of such proceedings will have a material adverse effect on the Company’s financial position, results of operations or cash flows . Other guarantees. The Company and its subsidiaries are party to various guarantee contracts in the normal course of business, which are generally supported by letters of credit issued by financial institutions. The Company’s senior credit facility limits the amount of letters of credit that can be issued to $250 million, the Operating Partnership’s senior credit facility limits the amount to $75 million, and MGM China’s credit facility limits the amount to $100 million. At June 30, 2019, $12 million in letters of credit were outstanding under the Company’s senior credit facility. No letters of credit were outstanding under the Operating Partnership’s senior credit facility or MGM China’s credit facility at June 30, 2019. The amount of available borrowings under each of the credit facilities are reduced by any outstanding letters of credit. In connection with the Extension Agreement, MGM Grand Paradise provided a bank guarantee in an amount of approximately $102 million to the government of Macau in May 2019 to warrant the fulfillment of labor debts upon the expiration of the Extension Agreement in June 2022.

Segment Information	NOTE 11 — SEGMENT INFORMATION The Company’s management views each of its casino resorts 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: Bellagio, MGM Grand Las Vegas (including The Signature), Mandalay Bay (including Delano and Four Seasons), The Mirage, Luxor, New York-New York (including the Park), Excalibur, Park MGM (including NoMad Las Vegas) and Circus Circus Las Vegas.

Related Party Transactions	NOTE 12 — RELATED PARTY TRANSACTIONS MGM China Ms. Ho, Pansy Catilina Chiu King (“Ms. Ho”) is a member of the Board of Directors of, and holds a minority ownership interest in, MGM China. MGM Branding and Development Holdings, Ltd. (together with its subsidiary MGM Development Services, Ltd., “MGM Branding and Development”), an entity included in the Company’s consolidated financial statements in which Ms. Ho indirectly holds a noncontrolling interest, is party to a brand license agreement and a development services agreement with MGM China, for which the related amounts are eliminated in consolidation. Entities owned by Ms. Ho received distributions in connection with her ownership of a noncontrolling interest in MGM Branding and Development Holdings, Ltd. of $5 million and $10 million during the three and six months ended June 30, 2019, respectively, and $4 million and $13 million during the three and six months ended June 30, 2018, respectively. MGP As described in Note 1, pursuant to the master lease, the tenant leases the real estate assets of The Mirage, Mandalay Bay, Luxor, New York-New York, Park MGM, Excalibur, The Park, Gold Strike Tunica, MGM Grand Detroit, Beau Rivage, Borgata, Empire City, MGM National Harbor and MGM Northfield Park from the landlord. Subsequent to the Company completing its acquisition of Empire City in January 2019, MGP acquired the developed real property associated with Empire City from the Company for consideration of approximately $634 million, which included the assumption of debt of approximately $246 million, which was immediately repaid, and the remaining paid through the issuance of Operating Partnership units. The real estate assets of Empire City were then leased to the Company pursuant to an amendment to the master lease, increasing the annual rent payment to MGP by $50 million, prorated for the remainder of the lease year. Consistent with the master lease terms, 90% of this rent will be fixed and contractually grow at 2% per year until 2022. In addition, the master lease provides the landlord with a right of first offer with respect to certain undeveloped land adjacent to the property to the extent the Company develops additional gaming facilities, which the landlord may exercise should the Company elect to sell this property in the future. On March 7, 2019, the tenant entered into an amendment to the existing master lease with respect to investments made by the Company related to the Park MGM and NoMad Las Vegas property (the “Park MGM Lease Transaction”). In connection with the transaction, the Company received consideration of $638 million, of which approximately $606 million was paid in cash and the remaining paid through the issuance of Operating Partnership units. Additionally, the annual rent payment to MGP was increased by $50 million, prorated for the remainder of the lease year. Consistent with the master lease terms, 90% of this rent will be fixed and contractually grow at 2% per year until 2022. Additionally, on April 1, 2019, the Company acquired the membership interests of Northfield from MGP, which held the operations of Northfield, for fair value of consideration of approximately $305 million consisting primarily of approximately 9 million Operating Partnership units that were ultimately redeemed by the Operating Partnership, and MGP retained the associated real estate assets. The Company then rebranded the property to MGM Northfield Park, which was then added to the existing master lease between the landlord and tenant, increasing the annual rent payment to MGP by $60 million. Consistent with the master lease terms, 90% of this rent will be fixed and contractually grow at 2% per year until 2022. The addition of Empire City and the Park MGM Lease Transaction in January 2019 and March 2019, respectively, increased annual rent payments associated with the master lease for the third lease year to $870 million from $770 million. All intercompany transactions, including transactions under the master lease and those described above, have been eliminated in the Company’s consolidation of MGP. The public ownership of MGP’s Class A shares is recognized as non-controlling interests in the Company’s consolidated financial statements.

Organization Consolidation And Presentation Of Financial Statements [Abstract]
Condensed Consolidating Financial Information	NOTE 13 — CONDENSED CONSOLIDATING FINANCIAL INFORMATION As of June 30, 2019, all of the Company’s principal debt arrangements are guaranteed by each of its material domestic subsidiaries, other than MGP and the Operating Partnership, MGM Grand Detroit, MGM National Harbor, MGM Springfield, and each of their respective subsidiaries. The Company’s international subsidiaries, including MGM China and its subsidiaries, are not guarantors of such indebtedness. Separate condensed financial statement information for the subsidiary guarantors and non-guarantors as of June 30, 2019 and December 31, 2018 and for the three and six months ended June 30, 2019 and 2018 are presented below. Within the Condensed Consolidating Statements of Cash Flows, the Company has presented net changes in intercompany accounts as investing activities if the applicable entities have a net asset in intercompany accounts and as a financing activity if the applicable entities have a net intercompany liability balance. Certain of the Company’s subsidiaries collectively own Operating Partnership units and each subsidiary accounts for its respective investment under the equity method within the condensed consolidating financial information presented below. Prior to the adoption of ASC 842 on January 1, 2019, for these subsidiaries, such investment constituted continuing involvement, and accordingly, the sale and leaseback of the real estate assets under the master lease did not qualify for sale-leaseback accounting. The real estate assets were reflected in the balance sheets of the applicable MGM subsidiaries. In addition, such subsidiaries recognized finance liabilities within “Other long-term obligations” related to rent payments due under the master lease and recognized the related interest expense component of such payments. These real estate assets were also reflected on the balance sheet of the MGP subsidiary that received such assets. The condensed consolidating financial information presented below therefore included the accounting for such activity within the respective columns presented and in the elimination column. In connection with the adoption of ASC 842, the sale and leaseback of the real estate assets under the master lease now qualify as a passed sale and are determined to be operating leases. As such, the real estate assets, finance liabilities, and related interest expense component of rent payments are no longer reflected in the results of the applicable MGM subsidiaries. Instead, the real estate assets are now only reflected on the balance sheet of the MGP subsidiary that received such assets and the MGM subsidiaries have recorded operating lease liabilities and operating ROU assets with the related rental payment reflected within “general and administrative” expense within the condensed consolidating financial information.

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 2018 annual consolidated financial statements and notes thereto included in the Company’s Annual Report on Form 10-K for the year ended December 31, 2018. 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. Management has determined that MGP is a variable interest entity (“VIE”) because the Class A equity investors 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 the primary beneficiary of MGP and consolidates MGP because (i) its ownership of MGP’s single Class B share entitles it to a majority of the total voting power of MGP’s shares, and (ii) the exchangeable nature of the Operating Partnership units owned provide the Company the right to receive benefits from MGP that could potentially be significant to MGP. The Company has recorded MGP’s ownership interest in the Operating Partnership of 31.7% as of June 30, 2019 as noncontrolling interest in the Company’s consolidated financial statements. As of June 30, 2019 and December 31, 2018, on a consolidated basis, MGP had total assets of $11.9 billion and $11.0 billion, respectively, primarily related to its real estate investments, and total liabilities of $5.5 billion and $5.1 billion, respectively, primarily related to its indebtedness. Reclassifications. Certain reclassifications have been made to conform the prior period presentation.
Revenue recognition	Revenue recognition. The Company’s revenue contracts with customers consist of casino wager transactions, hotel room sales, food and beverage transactions, entertainment shows, and retail transactions. For casino wager transactions that include incentives earned by customers under the Company’s loyalty programs, the Company allocates a portion of net win based upon the standalone selling price of such incentive (less estimated breakage). This allocation is deferred and recognized as revenue when the customer redeems the incentive. When redeemed, revenue is recognized in the department that provides the goods or service. Redemption of loyalty incentives at third party outlets are deducted from the loyalty liability and amounts owed are paid to the third party, with any discount received recorded as other revenue. During the three and six months ended June 30, 2019, commissions and incentives provided to gaming customers were $601 million and $1.2 billion, respectively. During the three and six months ended June 30, 2018, commissions and incentives provided to gaming customers were $520 million and $1.1 billion, respectively. After allocating revenue to other goods and services provided as part of casino wager transactions, the Company records the residual amount to casino revenue. 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, as discussed above, 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 Company’s 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 2019 2018 2019 2018 2019 2018 (in thousands) Balance at January 1 $ 323,811 $ 597,753 $ 113,293 $ 91,119 $ 667,285 $ 539,626 Balance at June 30 322,259 759,049 120,978 98,308 588,559 510,750 Increase / (decrease) $ (1,552 ) $ 161,296 $ 7,685 $ 7,189 $ (78,726 ) $ (28,876 ) 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 11. 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 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. For leases with terms greater than twelve months, the operating lease right-of-use (“ROU”) assets and operating lease liabilities are recognized based on the present value of the future minimum lease payments over the lease term at commencement date. The initial measurement of the operating lease ROU assets also include any prepaid lease payments and are reduced by any previously accrued deferred rent. When available, the Company uses the rate implicit in the lease to discount lease payments to present value; however, most of the Company’s leases do not provide a readily determinable implicit rate. Therefore, the Company uses its incremental borrowing rate to discount the lease payments based on the information available at commencement date. Many of the Company’s leases include fixed rental escalation clauses that are factored into the determination of lease payments. Lease terms include options to extend or terminate the lease when it is reasonably certain that such option will be exercised. Lease expense for minimum lease payments is recognized on a straight-line basis over the expected lease term. The Company is a lessor under certain of its lease arrangements. Lease revenues earned by the Company from third-party tenants 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, 2019, lease revenues from third-party tenants include $13 million and $25 million recorded within food and beverage revenue, respectively, and $22 million and $44 million recorded within entertainment, retail, and other revenue for the same such periods, respectively. During the three and six months ended June 30, 2018, lease revenues from third-party tenants include $12 million and $25 million recorded within food and beverage revenue, respectively, and $22 million and $43 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.
Recently issued accounting standards	Recently issued accounting standards. In February 2016, the FASB issued ASC 842 “Leases (Topic 842)”, which replaces the existing guidance in Topic 840, “Leases”, (“ASC 842”). ASC 842 is effective for fiscal years, and interim periods within those years, beginning after December 15, 2018. ASC 842 requires a dual approach for lessee accounting under which a lessee would classify and account for its lease agreements as either finance or operating. Both finance and operating leases will result in the lessee recognizing a ROU asset and a corresponding lease liability. For finance leases, the lessee will recognize interest expense associated with the lease liability and depreciation expense associated with the ROU asset; and for operating leases, the lessee will recognize straight-line rent expense. The Company adopted ASC 842 on January 1, 2019 utilizing the simplified transition method and accordingly did not recast comparative period financial information. The Company elected the basket of transition practical expedients which includes not needing to reassess: (1) whether any expired or existing contracts are or contain leases, (2) the lease classification for any expired or existing leases, and (3) direct costs for any existing leases. As a result of adoption, the Company recognized $656 million of operating ROU assets and $580 million of operating lease liabilities as of January 1, 2019. Prior to the adoption of ASC 842 on January 1, 2019, the master lease between subsidiaries of MGM and MGP was accounted for as a failed sale of the real estate assets due to the subsidiaries’ investments in the Operating Partnership, which constituted continuing involvement. As such, the real estate assets were reflected in the balance sheets of the applicable MGM subsidiaries as well as the associated finance lease liability. In connection with the adoption of ASC 842, the sale and leaseback of the real estate assets under the master lease now qualify as a passed sale and are determined to be operating leases. Accordingly , the real estate assets are now only reflected on the balance sheet of MGP and the MGM subsidiaries have recorded operating lease liabilities and operating ROU assets. The master lease and its related accounting eliminates in consolidation.
