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 . As of June 30, 2020, 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 and Excalibur. Operations at MGM Grand Las Vegas include management of The Signature at MGM Grand Las Vegas. The Company owns, along with local investors, and operates 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 and operates 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, except as otherwise agreed to in connection with the waiver agreement discussed below. As of June 30, 2020, the Company owned 56.7% of the Operating Partnership units, and MGP held the remaining 43.3% ownership interest in the Operating Partnership. Pursuant to a master lease agreement between a subsidiary of the Company and a subsidiary of the Operating Partnership, the Company leases 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, and MGM Northfield Park. Pursuant to a lease agreement between a subsidiary of the Company and a venture that is 5% owned by such subsidiary and 95% owned by a subsidiary of Blackstone Real Estate Income Trust, Inc. (“BREIT”), the Company leases the real estate assets of Bellagio from such venture (the “Bellagio BREIT Venture”) . Additionally, pursuant to a lease agreement between a subsidiary of the Company and a venture that is 50.1% owned by the Operating Partnership and 49.9% by a subsidiary of BREIT, the Company leases the real estate assets of Mandalay Bay and MGM Grand Las Vegas from such venture (the “MGP BREIT Venture”). Refer to Note 6 for further discussion of the leases. On February 14, 2020, the Company completed a series of transactions (collectively the “MGP BREIT Venture Transaction”) pursuant to which the real estate assets of MGM Grand Las Vegas and Mandalay Bay (including Mandalay Place) were contributed to the newly formed MGP BREIT Venture. In exchange for the contribution of the real estate assets, the Company received total consideration of $4.6 billion, which was comprised of $2.5 billion of cash, $1.3 billion of the Operating Partnership’s secured indebtedness assumed by MGP BREIT Venture, and the Operating Partnership’s 50.1% equity interest in the MGP BREIT Venture. In addition, the Operating Partnership issued approximately 3 million Operating Partnership units to the Company representing 5% of the equity value of MGP BREIT Venture. The Company recorded the difference between consideration received of $2.5 billion and the carrying value of the MGM Grand Las Vegas real estate assets of $733 million and selling costs of $27 million as a net gain on sale of assets of $1.7 billion, which is reflected within Gain on REIT transactions, net in the consolidated statements of operations . In connection with the MGP BREIT Venture Transaction, MGP BREIT Venture entered into a lease with a subsidiary of the Company for the real estate assets of Mandalay Bay and MGM Grand Las Vegas as further discussed in Note 6. Additionally, the existing master lease with MGP was modified to remove the Mandalay Bay property and the annual rent under the MGP master lease was reduced by $133 million, as further discussed in Note 11 Also, on January 14, 2020, the Company, the Operating Partnership, and MGP entered into an agreement for the Operating Partnership to waive its right following the closing of the MGP BREIT Venture Transaction to issue MGP Class A shares, in lieu of cash, to the Company in connection with the Company exercising its right to require the Operating Partnership to redeem Operating Partnership units that the Company holds, at a price per unit equal to a 3% discount to the ten day average closing price prior to the date of the notice of redemption. The waiver was effective upon closing of the transaction on February 14, 2020 and terminates on the earlier of February 14, 2022 or the Company receiving cash proceeds of $1.4 billion as consideration for the redemption of the Company’s Operating Partnership units. On May 18, 2020 the Operating Partnership redeemed approximately 30 million of the Operating Partnership units held by the Company for $700 million pursuant to the waiver agreement. 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 and MGM Cotai, two integrated casino, hotel and entertainment resorts in Macau, as well as the related gaming subconcession and land concessions. 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 3 for additional information related to CityCenter. The Company has three reportable segments: Las Vegas Strip Resorts, Regional Operations and MGM China. See Note 10 for additional information about the Company’s segments. Financial Impact of COVID-19. The novel coronavirus (“COVID-19”) pandemic has caused, and is continuing to cause, significant economic disruption both globally and in the United States, and has, and we expect will continue to have, a significant impact on the Company’s business, financial condition and results of operations. As of March 17, 2020, all of the Company’s domestic properties were temporarily closed to the public pursuant to state and local government requirements as a result of the unprecedented public health crisis from the COVID-19 pandemic. Throughout May, June, and July 2020, the Company re-opened most of its properties with limited amenities, and the Company expects to open additional venues and other properties as demand builds and if conditions permit. In addition, while certain properties have been able to re-open, such properties may be subject to temporary, complete or partial shutdowns in the future due to COVID-19. The Company has also implemented certain measures to mitigate the spread of COVID-19, including limits on the number of gaming tables allowed to operate and on the number of seats at each table game, as well as slot machine spacing, temperature checks, mask protection and other measures to enforce social distancing, including property capacity and venue/amenity restrictions. In Macau, pursuant to a request from the government of Macau, MGM China suspended all operations at MGM Macau and MGM Cotai for a 15-day period that commenced on February 5, 2020, other than operations that were necessary to provide sufficient non-gaming facilities to serve any remaining hotel guests in that period. While the properties have since re-opened, effective July 15, 2020, guests entering casinos are required to provide negative COVID-19 test results and the appropriate health declaration from the Macau government health agency. Although China has relaxed domestic travel restrictions in recent weeks, several travel and entry restrictions in Macau, Hong Kong, and certain cities and regions in mainland China remain in place ( including the temporary suspension of the visa scheme that permits mainland Chinese residents to travel to Macau, the temporary suspension of ferry services, and bans on entry or enhanced quarantine requirements), significantly impacting visitation to the Company’s Macau properties. While the Company has engaged in aggressive cost reduction efforts in connection with the closures, the Company still has significant fixed and variable expenses, which will adversely affect its profitability. In addition, the Company has seen, and expects to continue to see, weakened demand at its properties as a result of continued domestic and international travel restrictions or warnings, consumer fears and reduced consumer discretionary spending and general economic uncertainty. In light of the foregoing, the Company is unable to determine when its properties will return to pre-pandemic demand and pricing, or if the Company’s properties will remain re-opened, but it expects that the impact of COVID-19 will have a material impact on its consolidated results of operations during 2020 and potentially thereafter.

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 2019 annual consolidated financial statements and notes thereto included in the Company’s Annual Report on Form 10-K for the year ended December 31, 2019. 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. For entities not determined to be a variable interest entity (“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 if it has the direct or indirect ability to control the entities’ activities 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. All intercompany balances and transactions are eliminated in consolidation. The Company’s investments in unconsolidated affiliates are accounted for under the equity method when the Company can exercise significant influence over, or has joint control of, the unconsolidated affiliate, such as CityCenter and MGP BREIT Venture. 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 VIE. A VIE is an entity in which either (i) the equity investors as a group, if any, lack the power through voting or similar rights to direct the activities of such entity that most significantly impact such entity’s economic performance or (ii) the equity investment at risk is insufficient to finance that entity’s activities without additional subordinated financial support. The Company identifies the primary beneficiary of a VIE as the enterprise that has both of the following characteristics: (i) the power to direct the activities of the VIE that most significantly impact the entity’s economic performance; and (ii) the obligation to absorb losses or receive benefits of the VIE that could potentially be significant to the entity. The Company consolidates its investment in a VIE when it determines that it is its primary beneficiary. For these VIEs, the Company records a noncontrolling interest in the consolidated balance sheets. 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 MGP is a 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 as noncontrolling interest in the Company’s consolidated financial statements. As of June 30, 2020, on a consolidated basis MGP had total assets of $10.8 billion, primarily related to its real estate investments, and total liabilities of $4.5 billion, primarily related to its indebtedness. Management has determined that 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 and, accordingly, does not consolidate the venture, because the Company does not have power to direct the activities that could potentially be significant to the venture; BREIT, as the managing member, has such power. The Company has recorded its 5% ownership interest in Bellagio BREIT Venture as an investment in unconsolidated affiliates in the Company’s consolidated financial statements, for which such amount was $60 million as of June 30, 2020. The Company’s maximum exposure to loss as a result of its involvement with Bellagio BREIT Venture is equal to the carrying value of its investment, assuming no future capital funding requirements, plus the exposure to loss resulting from the Company’s guarantee of the debt of Bellagio BREIT Venture, as further discussed in Note 7. Reclassifications. Certain reclassifications have been made to conform the prior period presentation. Revenue recognition. The Company’s revenue from contracts with customers consists of casino wagers 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, 2020, commissions and incentives provided to gaming customers were $71 million and $526 million, respectively. 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. 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 2020 2019 2020 2019 2020 2019 (in thousands) Balance at January 1 $ 314,570 $ 323,811 $ 126,966 $ 113,293 $ 481,095 $ 667,285 Balance at June 30 338,390 322,259 131,641 120,978 306,752 588,559 Increase / (decrease) $ 23,820 $ (1,552 ) $ 4,675 $ 7,685 $ (174,343 ) $ (78,726 ) 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 10. Leases. The Company is a lessor under certain of its 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, 2020, lease revenues from third-party tenants include $5 million and $15 million recorded within food and beverage revenue, respectively, and $14 million and $33 million recorded within entertainment, retail, and other revenue for the same such periods, respectively. 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. Lease revenues from the rental of hotel rooms are recorded as rooms revenues within the consolidated statements of operations. Recently issued accounting standards. In June 2016, the FASB issued ASC 326 “Financial Instruments - Credit Losses (Topic 326): Measurements of Credit Losses on Financial Instruments” (“ASC 326”), which replaces the existing incurred loss model with a current expected credit loss (CECL) model that requires consideration of a broader range of reasonable and supportable information to inform credit loss estimates. The Company adopted ASC 326 on January 1, 2020, which did not have a material impact on its financial statements or accounting policies. The Company now utilizes a forward-looking current expected credit loss model for accounts receivables, guarantees, and other financial instruments. In December 2019, the FASB issued ASU 2019-12, “Income Taxes (Topic 740): Simplifying the Accounting for Income Taxes,” (“ASU 2019-12”), which simplifies the accounting for income taxes and includes removal of certain exceptions to the general principles of ASC 740, Income Taxes, and simplification in several other areas such as accounting for a franchise tax (or similar tax) that is partially based on income. ASU 2019-12 is effective for the Company beginning on January 1, 2021. Early adoption is permitted. The Company is currently assessing the impact ASU 2019-12 will have on its consolidated financial statements and footnote disclosures.

Income Tax Disclosure [Abstract]
Income Taxes	NOTE 5 — 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 22.4% and 2.9% for the three and six months ended June 30, 2020, respectively, compared to 13.3% and 36.9% for the three and six months ended June 30, 2019, 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. Due to the impact of COVID-19 on its business operations, the Company increased its valuation allowance for its foreign tax credits (“FTCs”) by $13 million and $27 million in the three and six months ended June 30, 2020, respectively, and increased its valuation allowance for Macau deferred tax assets by $25 million in the six months ended June 30, 2020, with corresponding increases to provision for income taxes in each period. In addition, during the six months ended June 30, 2020, the Company recorded an income tax benefit of $6 million resulting from recently issued guidance related to deductions for employee dining facilities and income tax expense of $349 million related to the MGP BREIT Venture Transaction that closed on February 14, 2020. The Company's 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 assumptions used in this assessment 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. On March 30, 2020, MGM Grand Paradise was granted an extension of its exemption from the Macau 12% complementary tax on gaming profits through June 26, 2022, concurrent with the end of the term of its gaming subconcession. The prior exemption was set to expire on March 31, 2020. The Company previously re-measured its net deferred tax liability for MGM Grand Paradise during 2019 assuming it would receive the complementary tax exemption extension through June 26, 2022 as a result of required non-discriminatory treatment among gaming concessionaires and sub-concessionaires under Macanese law. As a result, no additional remeasurement is required for the three and six months ended June 30, 2020. The Company continues to assume that MGM Grand Paradise will pay the Macau 12% complementary tax on gaming profits for all periods beyond June 26, 2022 and has factored that assumption into the measurement of Macau deferred tax assets and liabilities. MGM Grand Paradise’s exemption from the 12% complementary tax on gaming profits does not apply to dividend distributions of such profits to MGM China. MGM Grand Paradise has an agreement with the Macau government to settle the 12% complementary tax that would otherwise be due by its shareholder, MGM China, on distributions of its gaming profits by paying a flat annual payment (“annual fee arrangement”) regardless of the amount of distributable dividends. Such annual fee arrangement covers the distributions of gaming profits earned for the period of January 1, 2017 through March 31, 2020. MGM Grand Paradise has applied for an extension of the annual fee arrangement to cover distributions of gaming profits to be earned through June 26, 2022. Until the extension is granted, the 12% complementary tax will accrue on distributions of gaming profits earned after March 31, 2020; however, no amounts are accrued for the quarter ended June 30, 2020 since MGM Grand Paradise is generating losses due to the impact of COVID-19.

Commitments And Contingencies Disclosure [Abstract]
Commitments and Contingencies	NOTE 7 — COMMITMENTS AND CONTINGENCIES October 1 litigation. The Company and/or certain of its subsidiaries were 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. In connection with the mediation of these matters, the Company and law firms representing plaintiffs in the majority of pending matters and purporting to represent substantially all claimants known to the Company (collectively, the “Claimants”) have entered into a settlement agreement (the “Settlement Agreement”) whereby, subject to the satisfaction of certain monetary and non-monetary conditions, the Company’s insurance carriers will deposit funds into a settlement fund covering the plaintiffs and certain other cases that emerged or were filed prior to October 1, 2019. Pursuant to the terms of the Settlement Agreement, the total amount placed in the fund could range between $735 million and $800 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 by certain categories of claimants, as defined in the Settlement Agreement. Plaintiffs’ counsel have represented to the Company that they believe they have obtained 100% participation of the categories defined in the Settlement Agreement, such that the settlement amount is expected to be $800 million. The settlement amount is currently being reviewed by claims administrators. The Company has $751 million of insurance coverage available to fund the settlement. Following the mediation a few additional lawsuits were filed against the Company and/or certain of its subsidiaries. While it is possible that these lawsuits may be resolved as part of the Settlement Agreement, no assurances can be made that they will be. 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 believed it was in the best interests of all parties involved to negotiate and enter into the Settlement Agreement. As a result of the foregoing, the Company believes that it is probable a loss will be incurred and, as of June 30, 2020, the Company accrued a liability of $800 million. In addition, the Company recorded an insurance receivable of $751 million. The difference of $49 million between the liability and insurance receivable was recorded as an expense reflected within “Corporate expense” on the accompanying consolidated statements of operations for the three and six months ended June 30, 2020. While the Company intends for substantially all claimants to be covered by the Settlement Agreement, it remains possible that certain lawsuits may not be resolved by the settlement . If the conditions in the Settlement Agreement are not satisfied and the mediation stay is lifted, or if claims are litigated outside the settlement, 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 believes it ultimately 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 $850 million. At June 30, 2020, $10 million in letters of credit were outstanding under the Company’s senior credit facility. The Operating Partnership’s senior credit facility limits the amount of letters of credit that can be issued to $75 million. No letters of credit were outstanding under the Operating Partnership’s senior credit facility at June 30, 2020. The amount of available borrowings under each of the credit facilities is reduced by any outstanding letters of credit. MGM China guarantee. In connection with the extension of the expiration of the gaming subconcession to June 2022, MGM Grand Paradise provided a bank guarantee in an amount of approximately $103 million (when giving effect to foreign currency exchange rate fluctuations) to the government of Macau in May 2019 to warrant the fulfillment of an existing commitment of labor liabilities upon the expiration of the gaming subconcession in June 2022. Bellagio BREIT Venture guarantee. The Company provides a shortfall guarantee of the $3.01 billion principal amount of indebtedness (and any interest accrued and unpaid thereon) of Bellagio BREIT Venture, which matures in 2029. The terms of the shortfall guarantee provide that after the lenders have exhausted certain remedies to collect on the obligations under the indebtedness, the Company would then be responsible for any shortfall between the value of the collateral, which is the real estate assets of Bellagio owned by Bellagio BREIT Venture, and the debt obligation. This guarantee is accounted for under ASC 460 at fair value; such value is immaterial. MGP BREIT Venture guarantee. The Company provides a shortfall guarantee of the $3.0 billion principal amount of indebtedness (and any interest accrued and unpaid thereon) of MGP BREIT Venture, which has an initial term of twelve years, maturing in 2032, with an anticipated repayment date of March 2030. The terms of the shortfall guarantee provide that after the lenders have exhausted certain remedies to collect on the obligations under the indebtedness, the Company would then be responsible for any shortfall between the value of the collateral, which is the real estate assets of Mandalay Bay and MGM Grand Las Vegas, owned by MGP BREIT Venture, and the debt obligation. This guarantee is accounted for under ASC 460 at fair value; such value is immaterial. The Operating Partnership provides a guarantee for the losses incurred by the lenders of the indebtedness of the MGP BREIT Venture arising out of certain bad acts by the Operating Partnership, its venture partner, or the venture, such as fraud or willful misconduct, based on the party’s percentage ownership of the MGP BREIT Venture. This guarantee is capped at 10% of the principal amount outstanding at the time of the loss. The Operating Partnership and its venture partner have separately indemnified each other for the other party’s share of the overall liability exposure, if at fault. The guarantee is accounted for under ASC 460 at fair value; such value is immaterial.

Segment Reporting [Abstract]
Segment Information	NOTE 10 — 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 (until the sale of such property in December 2019). Regional Operations. Regional Operations consists of the following casino resorts: MGM Grand Detroit in Detroit, Michigan; Beau Rivage in Biloxi, Mississippi; Gold Strike Tunica in Tunica, Mississippi; Borgata in Atlantic City, New Jersey; MGM National Harbor in Prince George’s County, Maryland; MGM Springfield in Springfield, Massachusetts ; Empire City in Yonkers, New York (upon acquisition i n January 2019) ; and MGM Northfield Park in Northfield Park, Ohio (upon MGM’s acquisition of the operations from MGP i n Apri l 2019) . MGM China. MGM China consists of MGM Macau and MGM Cotai. The Company’s operations related to investments in unconsolidated affiliates, MGM Northfield Park (prior to April 1, 2019 as the operations were owned by MGP until that date), and certain other corporate operations and management services have not been identified as separate reportable segments; therefore, these operations are included in “Corporate and other” in the following segment disclosures to reconcile to consolidated results. As a result of the Bellagio transaction in the fourth quarter of 2019, the Company records rent expense associated with the triple-net operating lease with Bellagio BREIT Venture. In order to present profit and loss of each reportable segment on a similar economic basis, the rent expense associated with the triple-net operating leases and ground leases is added back within the financial information reviewed by the chief operating decision maker and as presented below, including recasting of prior year periods. The Company’s management utilizes Adjusted Property EBITDAR as the primary profit measure for its reportable segments and underlying operating segments. Adjusted Property EBITDAR is a measure defined as earnings before interest and other non-operating income (expense), taxes, depreciation and amortization, preopening and start-up expenses, gain on REIT transactions, net, restructuring costs (which represents costs related to severance, accelerated stock compensation expense, and consulting fees directly related to the operating model component of the MGM 2020 Plan), rent expense associated with triple-net operating and ground leases, income from unconsolidated affiliates related to investments in real estate ventures, and property transactions, net, and also excludes corporate expense and stock compensation expense, which are not allocated to each operating segment, and rent expense related to the master lease with MGP that eliminates in consolidation.

On February 14, 2020, the Company amended the MGP master lease to remove Mandalay Bay from such master lease and the annual rent under the MGP master lease was reduced by $133 million to $813 million. The annual rent payments under the MGP master lease for the fifth lease year, which commenced on April 1, 2020, increased to $828 million from $813 million, as a result of the fourth 2.0% fixed annual rent escalator that went into effect on April 1, 2020. Additionally, refer to Note 1 for discussion relating to the waiver agreement with MGP and the Operating Partnership units redeemed thereunder. All intercompany transactions, including transactions under the MGP master lease, have been eliminated in the Company’s consolidation of MGP. The public ownership of MGP’s Class A shares is recognized as non-controlling interests in the Company’s consolidated financial statements. Bellagio BREIT Venture The Company has a 5% ownership interest in the 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.

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 2019 annual consolidated financial statements and notes thereto included in the Company’s Annual Report on Form 10-K for the year ended December 31, 2019. 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. For entities not determined to be a variable interest entity (“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 if it has the direct or indirect ability to control the entities’ activities 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. All intercompany balances and transactions are eliminated in consolidation. The Company’s investments in unconsolidated affiliates are accounted for under the equity method when the Company can exercise significant influence over, or has joint control of, the unconsolidated affiliate, such as CityCenter and MGP BREIT Venture. 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 VIE. A VIE is an entity in which either (i) the equity investors as a group, if any, lack the power through voting or similar rights to direct the activities of such entity that most significantly impact such entity’s economic performance or (ii) the equity investment at risk is insufficient to finance that entity’s activities without additional subordinated financial support. The Company identifies the primary beneficiary of a VIE as the enterprise that has both of the following characteristics: (i) the power to direct the activities of the VIE that most significantly impact the entity’s economic performance; and (ii) the obligation to absorb losses or receive benefits of the VIE that could potentially be significant to the entity. The Company consolidates its investment in a VIE when it determines that it is its primary beneficiary. For these VIEs, the Company records a noncontrolling interest in the consolidated balance sheets. 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 MGP is a 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 as noncontrolling interest in the Company’s consolidated financial statements. As of June 30, 2020, on a consolidated basis MGP had total assets of $10.8 billion, primarily related to its real estate investments, and total liabilities of $4.5 billion, primarily related to its indebtedness. Management has determined that 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 and, accordingly, does not consolidate the venture, because the Company does not have power to direct the activities that could potentially be significant to the venture; BREIT, as the managing member, has such power. The Company has recorded its 5% ownership interest in Bellagio BREIT Venture as an investment in unconsolidated affiliates in the Company’s consolidated financial statements, for which such amount was $60 million as of June 30, 2020. The Company’s maximum exposure to loss as a result of its involvement with Bellagio BREIT Venture is equal to the carrying value of its investment, assuming no future capital funding requirements, plus the exposure to loss resulting from the Company’s guarantee of the debt of Bellagio BREIT Venture, as further discussed in Note 7.
Reclassifications	Reclassifications. Certain reclassifications have been made to conform the prior period presentation.
Revenue recognition	Revenue recognition. The Company’s revenue from contracts with customers consists of casino wagers 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, 2020, commissions and incentives provided to gaming customers were $71 million and $526 million, respectively. 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. 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 2020 2019 2020 2019 2020 2019 (in thousands) Balance at January 1 $ 314,570 $ 323,811 $ 126,966 $ 113,293 $ 481,095 $ 667,285 Balance at June 30 338,390 322,259 131,641 120,978 306,752 588,559 Increase / (decrease) $ 23,820 $ (1,552 ) $ 4,675 $ 7,685 $ (174,343 ) $ (78,726 ) 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 10. Leases. The Company is a lessor under certain of its 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, 2020, lease revenues from third-party tenants include $5 million and $15 million recorded within food and beverage revenue, respectively, and $14 million and $33 million recorded within entertainment, retail, and other revenue for the same such periods, respectively. 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. 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 June 2016, the FASB issued ASC 326 “Financial Instruments - Credit Losses (Topic 326): Measurements of Credit Losses on Financial Instruments” (“ASC 326”), which replaces the existing incurred loss model with a current expected credit loss (CECL) model that requires consideration of a broader range of reasonable and supportable information to inform credit loss estimates. The Company adopted ASC 326 on January 1, 2020, which did not have a material impact on its financial statements or accounting policies. The Company now utilizes a forward-looking current expected credit loss model for accounts receivables, guarantees, and other financial instruments. In December 2019, the FASB issued ASU 2019-12, “Income Taxes (Topic 740): Simplifying the Accounting for Income Taxes,” (“ASU 2019-12”), which simplifies the accounting for income taxes and includes removal of certain exceptions to the general principles of ASC 740, Income Taxes, and simplification in several other areas such as accounting for a franchise tax (or similar tax) that is partially based on income. ASU 2019-12 is effective for the Company beginning on January 1, 2021. Early adoption is permitted. The Company is currently assessing the impact ASU 2019-12 will have on its consolidated financial statements and footnote disclosures.
