Organization, Consolidation and Presentation of Financial Statements [Abstract]
Description of Business	DESCRIPTION OF BUSINESS Basis of Presentation Churchill Downs Incorporated (the "Company", "we", "our") financial statements are presented in conformity with the requirements of this Quarterly Report on Form 10-Q and consequently do not include all of the disclosures normally required by U.S. generally accepted accounting principles ("GAAP") or those normally made in our Annual Report on Form 10-K. The December 31, 2022 Condensed Consolidated Balance Sheet data was derived from audited financial statements but does not include all disclosures required by GAAP. The following information is unaudited. All per share amounts assume dilution unless otherwise noted. This report should be read in conjunction with our Annual Report on Form 10-K for the year ended December 31, 2022. In the opinion of management, all adjustments necessary for a fair statement of this information have been made, and all such adjustments are of a normal, recurring nature. We conduct our business through three reportable segments: Live and Historical Racing, TwinSpires, and Gaming. We aggregate our other businesses as well as certain corporate operations, and other immaterial joint ventures, in All Other. We report net revenue and operating expense associated with these reportable segments in the accompanying Condensed Consolidated Statements of Comprehensive Income. Stock Split Effective May 22, 2023, the Company's common stock was split two-for-one (the "Stock Split") with a proportionate increase in the number of its authorized shares of common stock. All share and per-share amounts have been retroactively adjusted to reflect the effects of the Stock Split. Refer to Note 8, Shareholders' Equity for further information on the Stock Split. Presque Isle Impairment During the second quarter, we evaluated economic conditions subsequent to the date of our annual impairment assessment on April 1, 2023, including competition in the market and inflationary pressures, which increased during the second quarter of 2023, and impacted the performance and outlook of Presque Isle Downs and Casino ("Presque Isle"). As a result, the Company concluded that a trigger event for impairment testing occurred related to the Presque Isle gaming rights, trademark, and the reporting unit's goodwill at the end of the second quarter. Based on the 2023 trigger event, the Company evaluated and subsequently updated the projected cash flows and discount rate to reflect the current environment. As a result, the Company recognized a non-cash impairment charge of $24.5 million in the second quarter of 2023 for the Presque Isle gaming rights and trademark. Refer to Note 5, Asset Impairments for further information on the impairment. Arlington Sale On February 15, 2023, we closed on the sale of the Arlington International Racecourse property ("Arlington") located in Arlington Heights, Illinois. We sold 326-acres to the Chicago Bears for $197.2 million. For more information, refer to Note 4, Dispositions. Acquisition of Peninsula Pacific Entertainment On November 1, 2022, the Company completed the acquisition of substantially all of the assets of Peninsula Pacific Entertainment LLC ("P2E") with a base purchase price of $2.75 billion ("P2E Transaction") subject to working capital and other purchase price adjustments. The P2E assets acquired included Colonial Downs Racetrack ("Colonial Downs") and six Historical Racing Machine ("HRM") entertainment venues in Virginia, del Lago Resort & Casino in New York ("del Lago"), and Hard Rock Hotel & Casino in Iowa ("Hard Rock Sioux City"), as well as the development rights for the Dumfries and Emporia HRM facilities in Virginia, up to five additional HRM entertainment venues in Virginia, and the potential for ONE Casino and Resort in Virginia in collaboration with Urban One, Inc. Refer to Note 3, Acquisitions for further information on the transaction. Acquisitions of Chasers Poker Room and Ellis Park On September 2, 2022, the Company completed the acquisition of Chasers Poker Room ("Chasers") in Salem, New Hampshire (the "Chasers Transaction"). As part of the transaction, we made an initial payment to the sellers for rights to operate the poker room and to build an HRM venue. Additional payments will be made once all necessary permits are obtained, and the planned historical racing entertainment venue is opened. The Company plans to develop an expanded charitable gaming facility in New Hampshire to accommodate HRMs and table games. On September 26, 2022, we completed the acquisition of Ellis Park Racing and Gaming ("Ellis Park") in Henderson, Kentucky, from Enchantment Holdings, LLC, an affiliate of Laguna Development Corporation, for total consideration of $79.0 million in cash, subject to certain working capital and other purchase price adjustments (the "Ellis Park Transaction"). Refer to Note 3, Acquisitions for further information on the transactions. Exit of the Direct Online Sports and Casino Business On February 24, 2022 the Company announced plans to exit the direct online sports and casino business. The Company has exited the direct online Sports and Casino business in every state except for Arizona.

Accounting Policies [Abstract]
Recent Accounting Pronouncements	RECENT ACCOUNTING PRONOUNCEMENTS Recent Accounting Pronouncements - effective in 2023 or thereafter In March 2020, the Financial Accounting Standards Board ("FASB") issued ASU 2020-04, Reference Rate Reform (Topic 848): Facilitation of the Effects of Reference Rate Reform on Financial Reporting, which provides optional expedients and exceptions to applying the guidance on contract modifications, hedge accounting, and other transactions, and to simplify the accounting for transitioning from the London Interbank Offered Rate ("LIBOR") and other interbank offered rates to alternative reference rates. The guidance was effective upon issuance. In December 2022, the FASB deferred the date for which this guidance can be applied from December 31, 2022 to December 31, 2024. The use of LIBOR was phased out at the end of 2021, although the phase-out of U.S. dollar LIBOR for existing agreements was delayed until June 2023. During the second quarter of 2023, the Company completed the transition of its financing from LIBOR to the Secured Overnight Financing Rate ("SOFR"). These transition activities did not have a material impact on the Company’s financial statements.

Business Combination and Asset Acquisition [Abstract]
Acquisitions	ACQUISITIONS Chasers Poker Room On September 2, 2022, the Company completed the Chasers Transaction which was treated as an asset acquisition because substantially all the value of the gross assets acquired was concentrated in the gaming rights. The Company made an initial payment at closing and recorded a liability for the remaining payments due on a future date. In conjunction with the acquisition, the Company recorded an $82.2 million gaming rights intangible asset which represented its fair value at the date of acquisition. The fair value of the gaming rights acquired in the Chasers Transaction was determined using the Greenfield Method, which is an income approach methodology that calculates the present value of the gaming rights intangible asset based on a projected cash flow stream. This method assumes that the gaming rights intangible asset provides the opportunity to develop a gaming or historical racing facility in a specified region, and that the present value of the projected cash flows is a result of the realization of advantages contained in these rights. Under this methodology, the acquirer is expected to absorb all start-up costs, as well as incur all expenses pertaining to the acquisition and/or the creation of all tangible and intangible assets. The estimated future revenue, future operating expenses, start-up costs, and discount rate were the primary inputs in the valuation. The gaming rights intangible asset was assigned an indefinite useful life based on the Company's expected use of the asset and determination that no legal, regulatory, contractual, competitive, economic, or other factors limit the useful life of the gaming rights. Ellis Park On September 26, 2022, the Company completed the Ellis Park Transaction for total consideration of $79.0 million in cash, plus $3.5 million in working capital and other preliminary purchase price adjustments. The fair values of the Ellis Park Transaction were based upon preliminary valuations. Estimates and assumptions used in such valuations are subject to change, which could be significant, within the measurement period up to one year from the acquisition date. The areas of the preliminary valuations that are not yet finalized relate to the amounts for income taxes, working capital adjustments and the final amount of residual goodwill. The Company expects to continue to obtain information to assist in determining fair values of net assets acquired at the acquisition date during the measurement period. The preliminary fair values as of June 30, 2023 for the assets acquired and liabilities assumed, net of cash acquired of $1.4 million, at the date of acquisition are as follows: property and equipment of $19.3 million, indefinite-lived gaming rights of $47.4 million, indefinite-lived trademark of $3.6 million, goodwill of $9.3 million, and net working capital of $1.5 million. The Company has not included other disclosures regarding the Chasers or Ellis Park Transactions as these transactions are immaterial to our business. P2E Transaction On November 1, 2022, the Company completed the acquisition of substantially all the ass ets of P2E for preliminary purchase consideration of $2,835.9 million, net of cash acquired. The P2E assets acquired included Colonial Downs and six HRM entertainment venues in Virginia, del Lago in New York, and Hard Rock Sioux City in Iowa, as well as the development rights for Dumfries and Emporia HRM facilities in Virginia, up to five additional HRM entertainment venues in Virginia, and the potential for ONE Casino & Resort in Virginia in collaboration with Urban One. The following table summarizes the preliminary fair value of the assets acquired and liabilities assumed, net of cash acquired of $126.4 million, as of November 1, 2022: (in millions) Total Accounts receivable, net $ 9.8 Other current assets 7.2 Property and equipment 611.2 Goodwill 347.8 Other intangible assets 1,941.5 Deferred taxes 20.8 Other assets 16.0 Total assets acquired $ 2,954.3 Accounts payable 4.0 Accrued expenses and other current liabilities 96.9 Other liabilities assumed 17.5 Total liabilities assumed $ 118.4 Net assets acquired (net of cash) $ 2,835.9 The fair value of the intangible assets consists of the following: (in millions) Fair Value Recognized Gaming rights $ 1,865.6 Trademark 75.9 Total intangible assets $ 1,941.5 Current assets and current liabilities were valued at the existing carrying values, as these items are short term in nature and represent management's estimated fair value of the respective items at November 1, 2022. The property and equipment acquired primarily relates to land, buildings, equipment, and furniture and fixtures. The fair value of the land was determined using the market approach and the fair values of the remaining property and equipment were primarily determined using the cost replacement method which is based on replacement or reproduction costs of the assets. The fair value of the gaming rights was determined using the Greenfield Method, which is an income approach methodology that calculates the present value of the overall business enterprise based on a projected cash flow stream. This method assumes that the gaming rights intangible assets provide the opportunity to develop a casino or historical racing facility in a specified region, and that the present value of the projected cash flows are a result of the realization of advantages contained in these rights. Under this methodology, the acquirer is expected to absorb all start-up costs, as well as incur all expenses pertaining to the acquisition and/or the creation of all tangible and intangible assets. The estimated future revenue and operating expenses, start-up costs, and discount rates were the primary assumptions and estimates in the valuation of the gaming rights. The gaming rights intangible assets were assigned an indefinite useful life based on the Company's expected use of the assets and determination that no legal, regulatory, contractual, competitive, economic, or other factors limit the useful life of the gaming rights. The trademark intangible assets were valued using the relief-from-royalty method of the income approach, which estimates the fair value of the intangible assets by discounting the fair value of the hypothetical royalty payments a market participant would be willing to pay to enjoy the benefits of the assets. The estimated future revenue, royalty rates, and discount rates were the primary assumptions and estimates in the valuation of the trademarks. The trademarks were assigned an indefinite useful life based on the Company’s intention to keep the trademarks for an indefinite period of time. Goodwill of $347.8 million was recognized due to the expected contribution of P2E to the Company's overall business strategy. The goodwill was assigned to the Gaming segment in the amount of $129.1 million and to the Live and Historical Racing segment in the amount of $218.7 million and is mostly deductible for tax purposes. Estimates and assumptions used in such valuations are subject to change, which could be significant, within the measurement period up to one year from the acquisition date. The preliminary purchase consideration is subject to adjustment upon finalization of customary post-closing adjustments related to working capital. The primary areas of the preliminary valuation that are not yet finalized relate to the fair values of amounts for income taxes, adjustments to working capital, and the final amount of residual goodwill. The Company expects to continue to obtain information to assist in determining fair values of net assets acquired at the acquisition date during the measurement period. The following unaudited pro forma consolidated financial information for the Company has been prepared assuming the P2E Transaction had occurred as of January 1, 2021. The unaudited pro forma financial information is not necessarily indicative of either future results of operations or results of operations that might have been achieved had the acquisition been consummated as of January 1, 2021.

Dispositions	DISPOSITIONS 2023 Dispositions Lady Luck Casino Nemacolin On June 26, 2023, the Company's management agreement for Lady Luck Casino Nemacolin ("Lady Luck") in Farmington, Pennsylvania expired and was not renewed. The Company completed the sale of substantially all of its assets at Lady Luck for an immaterial amount. Arlington On February 15, 2023, we closed on the sale of the Arlington property in Arlington Heights, Illinois, to the Chicago Bears for $197.2 million. We received net proceeds of $195.7 million for the 326-acres and recognized a gain of $114.0 million on the sale, which is included in other income in the accompanying Condensed Consolidated Statements of Comprehensive Income. Certain assets of Arlington totaling $82.0 million were classified held for sale as of December 31, 2022 on the accompanying Condensed Consolidated Balance Sheets. Arlington’s operations and assets are included in All Other in our consolidated results. The Company executed a forward like-kind exchange transaction by purchasing certain property as part of the P2E Transaction for $197.2 million, which qualified as an Internal Revenue Code §1031 transaction. An exchange accommodation titleholder ("EAT"), a type of variable interest entity, was used to facilitate this reverse like-kind exchange. The Company determined that it is the primary beneficiary of the EAT, thus the property held by the EAT has been consolidated and recorded in property and equipment, net on the Condensed Consolidated Balance Sheets.

Goodwill and Intangible Assets Disclosure [Abstract]
Asset Impairments	ASSET IMPAIRMENTS Presque Isle Impairment We performed our annual goodwill and indefinite-lived intangible assets impairment analysis for Presque Isle as of April 1, 2023. Based on the results of this analysis, no impairments for Presque Isle were identified. Subsequent to the annual test, we continued to evaluate economic conditions, including competition in the market and inflationary pressures, which increased during the second quarter of 2023, and impacted the performance and outlook of Presque Isle. As a result, the Company concluded that a trigger event for impairment testing occurred related to the Presque Isle gaming rights, trademark, and the reporting unit's goodwill at the end of the second quarter. Based on the 2023 trigger event, the Company evaluated and subsequently updated the projected cash flows and discount rate to reflect the current environment. As a result, the Company recognized a non-cash impairment charge of $24.5 million in the second quarter of 2023 for the Presque Isle gaming rights and trademark, which are included in the Gaming segment. The fair value of the Presque Isle gaming rights was determined using the Greenfield Method, an income approach methodology that calculates the present value based on a projected cash flow stream. The fair values of the trademark was determined by using the relief-from-royalty method of the income approach. The fair value of the Presque Isle reporting unit's goodwill was determined under the market and income valuation approaches using inputs primarily related to discounted projected cash flows and price multiples of comparable publicly traded companies. No impairment was recognized for the Presque Isle goodwill in second quarter of 2023.

Stock-based Compensation Plans	STOCK-BASED COMPENSATION PLANS We have stock-based employee compensation plans with awards outstanding under the Churchill Downs Incorporated 2016 Omnibus Stock Incentive Plan (the "2016 Plan") and the Executive Long-Term Incentive Compensation Plan, which was adopted pursuant to the 2016 Plan. Our total stock-based compensation expense, which includes expenses related to restricted stock awards ("RSAs"), restricted stock unit awards ("RSUs"), performance share unit awards ("PSUs"), and stock options associated with our employee stock purchase plan was $8.1 million and $16.7 million for the three and six months ended June 30, 2023 and $7.4 million and $14.4 million for the three and six months ended June 30, 2022, respectively. During the six months ended June 30, 2023, the Company awarded RSUs to employees, RSUs and PSUs to certain named executive officers ("NEOs"), and RSAs and RSUs to directors. The vesting criteria for the PSU awards granted in 2023 were based on a three-year service period with two performance conditions and a market condition related to relative total shareholder return ("TSR") consistent with prior year grants. The total compensation cost we will recognize under the PSUs is determined using the Monte Carlo valuation methodology, which factors in the value of the TSR market condition when determining the grant date fair value of the PSU. Compensation cost for each PSU is recognized during the performance and service period based on the probable achievement of the two performance criteria. The PSUs are converted into shares of our common stock at the time the PSU award value is finalized. A summary of the RSAs, RSUs and PSUs granted during 2023 is presented below (units in thousands): Grant Year Award Type Number of Units Awarded (1)(2) Vesting Terms 2023 RSU 114 Vest equally over three 2023 PSU 62 Three 2023 RSU 6 One 2023 RSA 4 One (1) PSUs reflect the target number of units for the original PSU grant.

Certain amendments to the Credit Agreement entered into during 2022 and 2023, respectively, are described below. On April 13, 2022, we amended the Credit Agreement to extend the maturity date of its Revolver to April 13, 2027, to increase the commitments under the existing revolving credit facility from $700.0 million to $1.2 billion, and to increase the swing line commitment from $50.0 million to $100.0 million. This amendment also provided for the senior secured Term Loan A due April 13, 2027 in the amount of $800.0 million, which was drawn on November 1, 2022 as part of the financing for the P2E Transaction. Refer to Note 3, Acquisitions for more information regarding the P2E Transaction. The Company capitalized $3.2 million of debt issuance costs associated with the Revolver commitment increase and $6.4 million of debt issuance costs associated with the Term Loan A which are being amortized as interest expense over the 5-year term. On February 24, 2023, we amended our Credit Agreement to increase the loans under the existing Term Loan A due 2027 from $800.0 million to $1.3 billion and made certain other changes to the existing credit agreement. The Company used the net proceeds from the borrowings under the increased Term Loan A to repay outstanding loans under its Revolver, pay related transaction fees and expenses, and for general corporate purposes. The Company capitalized $2.6 million of debt issuance costs associated with the increased Term Loan A which are being amortized as interest expense over the remainder of the 5-year term. The Company is required to pay a commitment fee on the unused portion of the Revolver as determined by a pricing grid based on the consolidated total net secured leverage ratio of the Company. For the period ended June 30, 2023, the Company's commitment fee rate was 0.25%. The Revolver and Term Loan A bear interest at SOFR plus 10 basis points, plus a variable applicable margin which is determined by the Company's net leverage ratio. As of June 30, 2023, that applicable margin was 150 basis points. The Term Loan B-1 bears interest at SOFR plus 210 basis points. The Company completed the transition of its financing from LIBOR to SOFR during the second quarter of 2023. These transition activities did not have a material impact on the Company’s financial statements. 2031 Senior Notes On April 25, 2023, the Company completed an offering of $600.0 million in aggregate principal amount of 6.750% senior unsecured notes that mature on April 25, 2031 (the "2031 Notes") in a private offering to qualified institutional buyers pursuant to Rule 144A that is exempt from registration under the Securities Act of 1933, as amended (the "Securities Act"), and to certain non-U.S. persons in accordance with Regulation S under the Securities Act. The Company used a portion of the net proceeds from the offering to repay indebtedness outstanding under its Term Loan B Facility due 2024 and to fund related transaction fees and expenses, working capital and other general corporate purposes. The Company recognized a loss on extinguishment on Term Loan B of $1.3 million, which is included in miscellaneous, net in the accompanying Condensed Consolidated Statements of Comprehensive Income. The Company capitalized $10.6 million of debt issuance costs associated with the 2031 Senior Notes which are being amortized as interest expense over the remainder of the 8-year term. The 2031 Notes were issued at 100% of the principal amount, plus interest deemed to have accrued from April 25, 2023, with interest payable in arrears on May 1st and November 1st of each year, commencing on November 1, 2023. The 2031 Notes will vote as one class under the indenture governing the 2031 Senior Notes. The 2031 Senior Notes were issued pursuant to an indenture, entered into on April 25, 2023 (the "2031 Indenture"), among the Company, certain subsidiaries of the Company as guarantors, and U.S. Bank National Association, as trustee. The Company may redeem some or all of the 2031 Senior Notes at any time at redemption prices set forth in the 2031 Indenture.

Revenue from Contracts with Customers	REVENUE FROM CONTRACTS WITH CUSTOMERS Performance Obligations As of June 30, 2023, our Live and Historical Racing segment had remaining performance obligations on contracts with a duration greater than one year relating to television rights, sponsorships, personal seat licenses, and admissions, with an aggregate transaction price of $126.8 million. The revenue we expect to recognize on these remaining performance obligations is $1.5 million for the remainder of 2023, $48.9 million in 2024, $38.1 million in 2025, and the remainder thereafter. As of June 30, 2023, our remaining performance obligations on contracts with a duration greater than one year in segments other than Live and Historical Racing were not material. Contract Assets and Contract Liabilities As of June 30, 2023 and December 31, 2022, contract assets were not material. As of June 30, 2023 and December 31, 2022, contract liabilities were $43.5 million and $58.7 million, respectively, which are included in current deferred revenue, non-current deferred revenue, and accrued expense in the accompanying Condensed Consolidated Balance Sheets. Contract liabilities primarily relate to the Live and Historical Racing segment and the decrease was primarily due to revenue recognized for fulfilled performance obligations. We recognized $38.8 million and $42.4 million of revenue during the three months and six months ended June 30, 2023, respectively, which was included in the contract liabilities balance at December 31, 2022. We recognized $43.6 million and $46.8 million of revenue during the three months and six months ended June 30, 2022, respectively, which was included in the contract liabilities balance at December 31, 2021. Disaggregation of Revenue The Company has included its disaggregated revenue disclosures as follows: • For the Live and Historical Racing segment, revenue is disaggregated between Churchill Downs Racetrack and historical racing properties given that our racing facilities revenues primarily revolve around live racing events while our historical racing properties revenues primarily revolve around historical racing. This segment is also disaggregated by location given the geographic economic factors that affect the revenue of service offerings. Within the Live and Historical racing segment, revenue is further disaggregated between live and simulcast racing, historical racing, racing event-related services, and other services. • For the TwinSpires segment, revenue is disaggregated between live and simulcast racing, gaming, and other services. • For the Gaming segment, revenue is disaggregated by location given the geographic economic factors that affect the revenue of gaming service offerings. Within the Gaming segment, revenue is further disaggregated between live and simulcast racing, racing event-related services, gaming, and other services. We believe that these disclosures depict how the amount, nature, timing, and uncertainty of cash flows are affected by economic factors.

Investments in and Advances to Unconsolidated Affiliates	INVESTMENTS IN AND ADVANCES TO UNCONSOLIDATED AFFILIATES Investments in and advances to unconsolidated affiliates as of June 30, 2023 and December 31, 2022 primarily consisted of a 61.3% interest in Rivers Casino Des Plaines ("Rivers Des Plaines"), a 50% interest in Miami Valley Gaming and Racing ("MVG"), and other immaterial joint ventures. Rivers Des Plaines The ownership of Rivers Des Plaines is comprised of the following: (1) the Company owns 61.3%, (2) High Plaines Gaming, LLC ("High Plaines"), an affiliate of Rush Street Gaming, LLC, owns 36.0%, and (3) Casino Investors, LLC owns 2.7%. Both the Company and High Plaines have participating rights over Rivers Des Plaines, and both must consent to operating, investing and financing decisions. As a result, we account for Rivers Des Plaines using the equity method. As of June 30, 2023 , the net aggregate basis difference between the Company’s investment in Rivers Des Plaines and the amounts of the underlying equity in net assets was $832.5 million. Our investment in Rivers Des Plaines was $531.4 million and $544.9 million as of June 30, 2023 and December 31, 2022, respectively. The Company received distributions from Rivers Des Plaines of $68.2 million and $61.3 million for the six months ended June 30, 2023 and 2022, respectively. Miami Valley Gaming Delaware North Companies Gaming & Entertainment Inc. ("DNC") owns the remaining 50% interest in MVG. Since both the Company and DNC have participating rights over MVG, and both must consent to MVG's operating, investing and financing decisions, we account for MVG using the equity method. Our investment in MVG was $113.3 million and $114.4 million as of June 30, 2023 and December 31, 2022, respectively. The Company received distributions from MVG of $23.5 million and $16.5 million for the six months ended June 30, 2023 and 2022, respectively.

Fair Value Disclosures [Abstract]
Fair Value of Assets And Liabilities	FAIR VALUE OF ASSETS AND LIABILITIES We endeavor to utilize the best available information in measuring fair value. Financial assets and liabilities are classified based on the lowest level of input that is significant to the fair value measurement. The following methods and assumptions are used to estimate the fair value of each class of financial instruments for which it is practicable to estimate. Restricted Cash Our restricted cash accounts held in money market and interest-bearing accounts qualify for Level 1 in the fair value hierarchy, which includes unadjusted quoted market prices in active markets for identical assets.

Commitments and Contingencies Disclosure [Abstract]
Contingencies	CONTINGENCIES We may be involved in litigation arising in the ordinary course of conducting business. We carry insurance for workers' compensation claims from our employees and general liability for claims from independent contractors, customers and guests. We are self-insured up to an aggregate stop loss for our general liability and workers' compensation coverages. We review all litigation on an ongoing basis when making accrual and disclosure decisions. For certain legal proceedings, we cannot reasonably estimate losses or a range of loss, if any, particularly for proceedings that are in the early stages of development or where the plaintiffs seek indeterminate damages. Various factors, including but not limited to, the outcome of potentially lengthy discovery and the resolution of important factual questions, may need to be determined before probability can be established or before a loss or range of loss can be reasonably estimated. In accordance with current accounting standards for loss contingencies and based upon information currently known to us, we establish reserves for litigation when it is probable that a loss associated with a claim or proceeding has been incurred and the amount of the loss or range of loss can be reasonably estimated. When no amount within the range of loss is a better estimate than any other amount, we accrue the minimum amount of the estimable loss. To the extent that such litigation against us may have an exposure to a loss in excess of the amount we have accrued, we believe that such excess would not be material to our consolidated financial condition, results of operations, or cash flows. Legal fees are expensed as incurred. If the loss contingency in question is not both probable and reasonably estimable, we do not establish an accrual and the matter will continue to be monitored for any developments that would make the loss contingency both probable and reasonably estimable. In the event that a legal proceeding results in a substantial judgment against us, or settlement by us, there can be no assurance that any resulting liability or financial commitment would not have a material adverse impact on our business.

Segment Reporting [Abstract]
Segment Information	SEGMENT INFORMATION We manage our operations through three reportable segments: Live and Historical Racing, TwinSpires, and Gaming. Our operating segments reflect the internal management reporting used by our chief operating decision maker to evaluate results of operations and to assess performance and allocate resources. We have aggregated Arlington as well as certain corporate operations, and other immaterial joint ventures in All Other to reconcile to consolidated results. Eliminations include the elimination of intersegment transactions. We utilize non-GAAP measures, including EBITDA (earnings before interest, taxes, depreciation and amortization) and Adjusted EBITDA. Our chief operating decision maker utilizes Adjusted EBITDA to evaluate segment performance, develop strategy and allocate resources. Adjusted EBITDA includes the following adjustments: Adjusted EBITDA includes our portion of EBITDA from our equity investments. Adjusted EBITDA excludes: • Transaction expense, net which includes: – Acquisition, disposition, and property sale related charges; – Direct online Sports and Casino business exit costs; and – Other transaction expense, including legal, accounting, and other deal-related expense; • Stock-based compensation expense; • Rivers Des Plaines' impact on our investments in unconsolidated affiliates from: – The impact of changes in fair value of interest rate swaps; and – Legal reserves and transaction costs; • Asset impairments; • Gain on property and asset sales; • Legal reserves; • Pre-opening expense; and • Other charges, recoveries, and expenses On June 26, 2023, the Company's management agreement for Lady Luck expired and was not renewed. The Company completed the sale of substantially all of its assets at Lady Luck for an immaterial amount. As of December 31, 2021, Arlington ceased racing and simulcast operations and the property was sold on February 15, 2023 to the Chicago Bears. Arlington's results and exit costs in 2022 and 2023 are treated as an adjustment to EBITDA. We utilize the Adjusted EBITDA metric to provide a more accurate measure of our core operating results and enable management and investors to evaluate and compare from period to period our operating performance in a meaningful and consistent manner. Adjusted EBITDA should not be considered as an alternative to operating income as an indicator of performance, as an alternative to cash flows from operating activities as a measure of liquidity, or as an alternative to any other measure provided in accordance with GAAP. Our calculation of Adjusted EBITDA may be different from the calculation used by other companies and, therefore, comparability may be limited. For segment reporting, Adjusted EBITDA includes intercompany revenue and expense totals that are eliminated in the accompanying Consolidated Statements of Comprehensive Income. The tables below present net revenue from external customers, Adjusted EBITDA by segment and reconciles comprehensive income to Adjusted EBITDA: Net revenue by segment is comprised of the following: Three Months Ended June 30, Six Months Ended June 30, (in millions) 2023 2022 2023 2022 Live and Historical Racing $ 385.0 $ 260.9 $ 599.4 $ 346.9 TwinSpires 137.4 136.8 232.2 237.1 Gaming 245.9 184.3 495.9 361.6 All Other 0.2 0.5 0.5 1.0 Net Revenue $ 768.5 $ 582.5 $ 1,328.0 $ 946.6 Adjusted EBITDA by segment is comprised of the following: Three Months Ended June 30, 2023 (in millions) Live and Historical Racing TwinSpires Gaming Revenues $ 408.0 $ 139.1 $ 247.9 Taxes and purses (85.4) (7.0) (81.7) Marketing and advertising (12.1) (5.3) (9.0) Salaries and benefits (30.3) (7.5) (39.5) Content expense (2.0) (68.7) (2.7) Selling, general and administrative expense (7.3) (2.7) (10.3) Other operating expense (47.6) (14.0) (30.0) Other income 0.2 — 48.7 Adjusted EBITDA $ 223.5 $ 33.9 $ 123.4 Three Months Ended June 30, 2022 (in millions) Live and Historical Racing TwinSpires Gaming Revenues $ 275.9 $ 138.5 $ 184.5 Taxes and purses (59.6) (7.2) (68.2) Marketing and advertising (6.4) (5.0) (3.7) Salaries and benefits (18.9) (6.9) (23.5) Content expense (1.0) (68.1) (2.2) Selling, general and administrative expense (3.0) (2.6) (6.7) Other operating expense (23.2) (14.8) (22.2) Other income 0.1 — 48.8 Adjusted EBITDA $ 163.9 $ 33.9 $ 106.8 Six Months Ended June 30, 2023 (in millions) Live and Historical Racing TwinSpires Gaming Revenues $ 623.8 $ 235.5 $ 499.5 Taxes and purses (141.9) (12.0) (165.3) Marketing and advertising (20.3) (6.7) (17.6) Salaries and benefits (52.1) (13.7) (74.0) Content expense (3.5) (111.7) (4.5) Selling, general and administrative expense (16.0) (5.1) (22.5) Other operating expense (84.6) (24.0) (60.0) Other income 0.2 1.0 97.3 Adjusted EBITDA $ 305.6 $ 63.3 $ 252.9 Six Months Ended June 30, 2022 (in millions) Live and Historical Racing TwinSpires Gaming Revenues $ 363.1 $ 239.9 $ 363.7 Taxes and purses (86.4) (14.7) (135.5) Marketing and advertising (9.3) (10.1) (7.2) Salaries and benefits (29.8) (13.6) (47.4) Content expense (1.6) (111.2) (3.7) Selling, general and administrative expense (6.3) (5.2) (13.3) Other operating expense (38.0) (27.1) (42.2) Other income 0.1 — 83.5 Adjusted EBITDA $ 191.8 $ 58.0 $ 197.9 Adjusted EBITDA by segment is comprised of the following: Three Months Ended June 30, Six Months Ended June 30, (in millions) 2023 2022 2023 2022 Reconciliation of Comprehensive Income to Adjusted EBITDA: Net income and comprehensive income $ 143.0 $ 339.3 $ 298.7 $ 381.4 Additions: Depreciation and amortization 41.8 26.1 79.7 51.2 Interest expense, net 65.2 35.1 129.9 56.4 Income tax provision 56.2 140.6 109.4 157.1 EBITDA $ 306.2 $ 541.1 $ 617.7 $ 646.1 Adjustments to EBITDA: Stock-based compensation expense $ 8.1 $ 7.4 $ 16.7 $ 14.4 Legal reserve — 3.2 — 3.2 Pre-opening expense 3.2 2.6 6.4 4.7 Arlington exit costs 5.9 1.8 9.3 4.3 Other expenses, net 6.6 — 6.9 — Transaction expense, net 0.5 1.2 0.3 6.2 Asset impairments 24.5 — 24.5 4.9 Other income, expense: Interest, depreciation and amortization expense related to equity investments 9.9 10.5 19.7 21.6 Changes in fair value of Rivers Des Plaines' interest rate swaps — (2.2) — (12.6) Rivers Des Plaines' legal reserves and transaction costs — 0.2 — 0.5 Other charges and recoveries, net (1.2) — (0.9) 1.0 Gain on sale of assets — (274.6) (114.0) (274.6) Total adjustments to EBITDA 57.5 (249.9) (31.1) (226.4) Adjusted EBITDA $ 363.7 $ 291.2 $ 586.6 $ 419.7 Adjusted EBITDA by segment: Live and Historical Racing $ 223.5 $ 163.9 $ 305.6 $ 191.8 TwinSpires 33.9 33.9 63.3 58.0 Gaming 123.4 106.8 252.9 197.9 Total segment Adjusted EBITDA 380.8 304.6 621.8 447.7 All Other (17.1) (13.4) (35.2) (28.0) Total Adjusted EBITDA $ 363.7 $ 291.2 $ 586.6 $ 419.7 The table below presents total asset information for each of our segments: (in millions) June 30, 2023 December 31, 2022 Total assets: Live and Historical Racing $ 3,552.8 $ 3,345.4 TwinSpires 288.3 287.9 Gaming 1,802.8 1,824.2 Total segment assets 5,643.9 5,457.5 All Other 934.7 749.3 Total assets $ 6,578.6 $ 6,206.8 The table below presents total capital expenditures for each of our segments: Six Months Ended June 30, (in millions) 2023 2022 Capital expenditures: Live and Historical Racing $ 239.8 $ 119.8 TwinSpires 6.4 6.0 Gaming 62.4 40.4 Total segment capital expenditures 308.6 166.2 All Other 3.8 0.9 Total capital expenditures $ 312.4 $ 167.1

Accounting Policies [Abstract]
Recent Accounting Pronouncements - effective in 2023 or thereafter	Recent Accounting Pronouncements - effective in 2023 or thereafter In March 2020, the Financial Accounting Standards Board ("FASB") issued ASU 2020-04, Reference Rate Reform (Topic 848): Facilitation of the Effects of Reference Rate Reform on Financial Reporting, which provides optional expedients and exceptions to applying the guidance on contract modifications, hedge accounting, and other transactions, and to simplify the accounting for transitioning from the London Interbank Offered Rate ("LIBOR") and other interbank offered rates to alternative reference rates. The guidance was effective upon issuance. In December 2022, the FASB deferred the date for which this guidance can be applied from December 31, 2022 to December 31, 2024. The use of LIBOR was phased out at the end of 2021, although the phase-out of U.S. dollar LIBOR for existing agreements was delayed until June 2023. During the second quarter of 2023, the Company completed the transition of its financing from LIBOR to the Secured Overnight Financing Rate ("SOFR"). These transition activities did not have a material impact on the Company’s financial statements.
