Basis of Presentation [Abstract]
Description of Business	DESCRIPTION OF BUSINESS Basis of Presentation The Churchill Downs Incorporated (the "Company", "we", "us", "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, 2019 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, 2019. 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: Churchill Downs, Online Wagering, 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. Impact of COVID-19 Pandemic In March 2020, the World Health Organization declared the COVID-19 outbreak a global pandemic. Considerable uncertainty still surrounds the COVID-19 virus and its potential effects, and the extent of and effectiveness of responses taken on international, national and local levels. Measures taken to limit the impact of COVID-19, including shelter-in-place orders, social distancing measures, travel bans and restrictions, and business and government shutdowns, have resulted and continue to result in significant negative economic impacts in the United States and in relation to our business. The long-term impact of COVID-19 on the United States and world economies and continuing impact on our business remains uncertain, the duration and scope of which cannot currently be predicted. In response to the measures taken to limit the impact of COVID-19 described above, and for the protection of our employees, customers, and communities, we temporarily suspended operations at our properties in March 2020. In May 2020, we began to reopen our properties with patron restrictions and gaming limitations. As of September 30, 2020, all of our properties had reopened and remain open with applicable restrictions. We also implemented other initiatives to facilitate social distancing and enhanced cleaning, such as increased frequency of cleaning and sanitizing of all high-touch surfaces, mandatory temperature checks of all guests and team members upon entry and required training for all team members on safety protocols. Certain amenities at our properties have continued to be suspended, including all of our food buffets and valet services, and certain restaurants and food outlets.

On March 25, 2020, as a result of the temporary closures and suspended operations described above, the Company announced the temporary furlough of employees at its wholly-owned and managed gaming properties and certain racing operations. As the Company has reopened these properties, certain employees have returned to work while others remain on temporary furlough due to the capacity restrictions at these properties. The Company provided health, dental, vision and life insurance benefits to furloughed employees through July 31, 2020. The Company also implemented a temporary salary reduction for all remaining non-furloughed salaried employees based on a percentage that varies dependent upon the amount of each employee’s salary. The most senior level of executive management received the largest salary decrease, based on both percentage and dollar amount. Salaries for non-furloughed employees resumed at the annual base salary beginning with the start of the employee's first full pay period subsequent to July 31, 2020. Financial Status and Outlook The Company reduced its planned maintenance and project capital expenditures for 2020 as a result of the temporary property and operations closures and has prioritized its capital investments based on the highest near-term return opportunities in order to maintain financial flexibility. On March 16, 2020, we borrowed $675.4 million on our revolving credit facility (the "Revolver") pursuant to the Credit Agreement (defined below) to provide the Company with additional financial flexibility. The Company had $622.0 million of cash and cash equivalents as of September 30, 2020. On April 28, 2020, the Company entered into a Second Amendment to its Credit Agreement, which (i) provides for a financial covenant relief period through the date on which the Company delivers its quarterly financial statements and compliance certificate for the fiscal quarter ending June 30, 2021, subject to certain exceptions (the “Financial Covenant Relief Period”), (ii) amends the definition of “Consolidated EBITDA” in the Credit Agreement with respect to the calculation of Consolidated EBITDA for the first two fiscal quarters after the termination of the Financial Covenant Relief Period, (iii) extends certain deadlines and makes certain other amendments to the Company’s financial reporting obligations, (iv) places certain restrictions on restricted payments during the Financial Covenant Relief Period, and (v) amends the definitions of “Material Adverse Effect” and “License Revocation” in the Credit Agreement to take into consideration COVID-19. During the Financial Covenant Relief Period, the Company will not be required to comply with the consolidated total secured net leverage ratio financial covenant and the interest coverage ratio financial covenant. The Company has agreed to a minimum liquidity financial covenant that requires the Company and its restricted subsidiaries to maintain liquidity of at least $150.0 million during the Financial Covenant Relief Period. We continue to assess the situation at our properties and operations on a daily basis; however, we are unable to determine when the current restrictions in place for our opened properties will be removed. Our third quarter of 2020 financial results were materially impacted by the rescheduling of the 146th Kentucky Oaks and Derby from the second quarter of 2020 to the third quarter of 2020 without spectators, by the temporary suspension of operations at certain properties, and continued property restrictions. Based on our current projected operating cash flow needs, interest and debt repayments, and revised maintenance and project capital expenditures, we believe we have adequate cash to fund our business operations, meet all of our financial commitments, and invest in our prioritized key growth capital projects for well beyond the next twelve months. Oak Grove Racing, Gaming & Hotel On September 18, 2020, the Company opened its simulcast and historical racing machine ("HRM") operations at Oak Grove Racing, Gaming & Hotel ("Oak Grove"), located in Oak Grove, Kentucky.

On March 8, 2019, the Company assumed management and acquired certain assets related to the management of Lady Luck Nemacolin in Farmington, Pennsylvania, from ERI for cash consideration of $100,000 (the "Lady Luck Nemacolin Transaction").

Accounting Changes and Error Corrections [Abstract]
Recent Accounting Pronouncements	RECENT ACCOUNTING PRONOUNCEMENTS Recent Accounting Pronouncement - Adopted on January 1, 2020 In June 2016, the Financial Accounting Standards Board ("FASB") issued Accounting Standards Update ("ASU") No. 2016-13, Financial Instruments - Credit Losses, ("ASC 326") which introduces a new model for recognizing credit losses on financial instruments based on an estimate of current expected credit losses. The new model will apply to: (1) loans, accounts receivable, trade receivables, and other financial assets measured at amortized cost, (2) loan commitments and certain other off-balance sheet credit exposures, (3) debt securities and other financial assets measured at fair value through other comprehensive income, and (4) beneficial interests in securitized financial assets. We adopted ASC 326 on January 1, 2020 using the modified retrospective approach. We recognized the cumulative effect of applying ASC 326 as an opening balance sheet adjustment at January 1, 2020. The comparative information has not been retrospectively adjusted and continues to be reported under the accounting standards in effect for those periods. The adoption of ASC 326 did not have a material impact on our business. In January 2017, the FASB issued ASU No. 2017-04, Intangibles - Goodwill and Other: Simplifying the Test for Goodwill Impairment. This new guidance simplifies the accounting for goodwill impairments by removing step two from the goodwill impairment test. Instead, if the carrying amount of a reporting unit exceeds its fair value, an impairment loss shall be recognized in an amount equal to that excess. We adopted this guidance on January 1, 2020. The new guidance did not result in a cumulative adjustment upon adoption and there was no impairment recognized under the new guidance for the three or nine months ended September 30, 2020.

Goodwill and Intangible Assets Disclosure [Abstract]
Asset Impairment	ASSET IMPAIRMENT During the quarter ended March 31, 2020, the Company evaluated whether events or circumstances changed that would indicate it is more likely than not that any of its intangible assets, goodwill, or property and equipment, were impaired ("Trigger Event"), or if there were any other than temporary impairments of our equity investments. Factors considered in this evaluation included, among other things, the amount of the fair value over carrying value from the annual impairment testing performed as of April 1, 2019, changes in carrying values, changes in discount rates, and the impact of temporary property closures due to the COVID-19 pandemic on cash flows. Based on the Company's evaluation, the Company concluded that a Trigger Event occurred related to the Presque Isle gaming rights, trademark, and the reporting unit's goodwill due to the impact and uncertainty of the COVID-19 pandemic and the recent closing of the Presque Isle Transaction in 2019. The initial fair value of Presque Isle gaming rights in the first quarter of 2019 was determined using the Greenfield Method, which is an income approach methodology that calculates the present value based on a projected cash flow stream. This method assumes that the Presque Isle gaming rights provide the opportunity to develop a casino and online wagering platform 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, operating expenses, start-up costs, and discount rate were the primary inputs in the valuation. Based on the Trigger Event, the Company updated the discount rate to reflect the increased uncertainty of the cash flows and updated the projected cash flow stream. As a result, the Company recognized an impairment of $15.0 million in first quarter of 2020 for its Presque Isle gaming rights ($12.5 million related to the Gaming segment and $2.5 million related to the Online Wagering segment). The Presque Isle trademark was initially valued in first quarter of 2019 using the relief-from-royalty method of the income approach, which estimates the fair value of the intangible asset by discounting the fair value of the hypothetical royalty payments a market participant would be willing to pay to enjoy the benefits of the asset. The estimated future revenue, royalty rate, and discount rate were the primary inputs in the valuation of the trademark. Based on the Trigger Event, the Company updated the discount rate to reflect the increased uncertainty of the cash flows and updated projected cash flow stream. As a result, the Company recognized an impairment of $2.5 million in first quarter of 2020 for its Presque Isle trademark. 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 publicly traded comparable companies. In accordance with Accounting Standards Codification 350, Intangibles - Goodwill and Other, the Company performed its impairment testing of the Presque Isle gaming rights and trademark prior to testing Presque Isle goodwill. Based on the Trigger Event, the Company updated the discount rate to reflect the increased uncertainty of the cash flows and updated project cash flow stream. As a result, the Company did not recognize an impairment for Presque Isle goodwill in the first quarter of 2020 because the fair value exceeded the carrying value.

Income Taxes	INCOME TAXES The Company’s effective income tax rate for the three months ended September 30, 2020 was higher than the U.S. federal statutory rate of 21.0% primarily resulting from tax expense during a period of pre-tax income from nondeductible officer’s compensation and state income taxes, partially offset by tax benefits during a period of pre-tax income from a current year estimated federal taxable loss which will be carried back to a pre-2018 tax year, and a decrease in our unrecognized tax benefits due to the expiration of the federal income tax statute of limitations. The Company’s effective income tax rate for the nine months ended September 30, 2020 was higher than the U.S. federal statutory rate of 21.0% primarily resulting from tax benefits during a period of pre-tax loss from a current year estimated federal taxable loss which will be carried back to a pre-2018 tax year, year-to-date tax deductions from vesting of stock awards in excess of book deductions, state income taxes, and a decrease in our unrecognized tax benefits due to the expiration of the federal income tax statute of limitations, partially offset by tax expense during a period of pre-tax loss from nondeductible officer’s compensation.

The First Amendment extends the maturity for the Company’s Revolver to at least September 27, 2024, which is 91 days prior to the latest maturity date of the Company’s term loan facility on December 27, 2024. Previously, the maturity date of the revolving credit facility was December 27, 2022. The interest rates applicable to the Company’s borrowings under the Credit Agreement are LIBOR-based plus a spread, determined by the Company’s consolidated total net leverage ratio. The First Amendment, among other things, lowers the upper limit of the applied spreads with respect to revolving loans from 2.25% to 1.75% and for commitment fees with respect thereto from 0.35% to 0.30%, and generally offers a reduced pricing schedule for outstanding borrowings and commitment fees with respect to the Revolver across all other leverage pricing levels. The interest rates applicable to borrowings under the facilities are LIBOR-based plus a spread, determined by the Company’s consolidated total net leverage ratio. The First Amendment does not alter the Company’s borrowing capacity. The Company capitalized $2.0 million of debt issuance costs associated with the First Amendment which are amortized as interest expense over the remaining duration of the Revolver. On March 16, 2020, we borrowed $675.4 million on our Revolver to provide the Company with additional financial flexibility.

Revenue from Contracts with Customers	REVENUE FROM CONTRACTS WITH CUSTOMERS Performance Obligations As of September 30, 2020, the Churchill Downs segment had remaining performance obligations, on contracts with a duration greater than one year, with an aggregate transaction price of $133.2 million. The revenue we expect to recognize on these remaining performance obligations is $0.4 million for the remainder of 2020, $41.2 million in 2021, $34.2 million in 2022, and the remainder thereafter. As of September 30, 2020, our remaining performance obligations in segments other than Churchill Downs were not material. Contract Assets and Contract Liabilities As of September 30, 2020 and December 31, 2019, contract assets were not material. As of September 30, 2020 and December 31, 2019, contract liabilities were $60.0 million and $63.1 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 Churchill Downs segment and the increase was primarily due to cash payments received for unfulfilled performance obligations. We recognized $1.7 million of revenue during the three months ended September 30, 2020 and $5.8 million of revenue during the nine months ended September 30, 2020 that was included in the contract liabilities balance at December 31, 2019.

Disaggregation of Revenue In Note 18, Segment Information, the Company has included its disaggregated revenue disclosures as follows: • For the Churchill Downs segment, revenue is disaggregated between Churchill Downs Racetrack and Derby City Gaming given that Churchill Downs Racetrack's revenues primarily revolve around live racing events while Derby City Gaming's revenues primarily revolve around historical racing events. Within the Churchill Downs segment, revenue is further disaggregated between live and simulcast racing, historical racing, racing event-related services, and other services. • For the Online Wagering segment, revenue is disaggregated between TwinSpires and online sports betting and iGaming business given that TwinSpires' revenue is primarily related to online pari-mutuel wagering on live race events while online sports betting and iGaming revenue relates to casino gaming service offerings. Online sports betting and iGaming service offerings are currently nominal. Within the Online Wagering segment, revenue is further 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.

Following the closing of the Sale Transaction, the parties completed the Recapitalization pursuant to which Midwest Gaming used approximately $300.0 million in proceeds from amended and extended credit facilities to redeem, on a pro rata basis, additional Midwest Gaming units held by High Plaines and Casino Investors. As a result of the Recapitalization, the Company's ownership of Midwest Gaming increased to 61.3%.

Under the new limited liability company agreement, both the Company and High Plaines have participating rights over Midwest Gaming, and both must consent to Midwest Gaming's operating, investing and financing decisions. As a result, we account for Midwest Gaming using the equity method. The Company’s investment in Midwest Gaming is presented at our initial cost of investment plus its accumulated proportional share of income or loss, including depreciation/accretion of the difference in the historical basis of the Company’s contribution, less any distributions it has received.

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 that are held in interest-bearing accounts qualify for Level 1 in the fair value hierarchy, which includes unadjusted quoted market prices in active markets for identical assets. Debt The fair value of the Company’s 4.75% Senior Notes due 2028 (the "2028 Senior Notes") and 5.500% Senior Notes due 2027 (the "2027 Senior Notes") are estimated based on unadjusted quoted prices for identical or similar liabilities in markets that are not active and as such are Level 2 measurements. The fair values of the Company's $400.0 million Senior Secured Term Loan B (the "Term Loan B") and Revolver under the Credit Agreement approximate the gross carrying value of the variable rate debt and as such are Level 2 measurements. The carrying amounts and estimated fair values by input level of the Company's financial instruments are as follows: September 30, 2020 (in millions) Carrying Amount Fair Value Level 1 Level 2 Level 3 Financial assets: Restricted cash $ 57.6 $ 57.6 $ 57.6 $ — $ — Financial liabilities: Term Loan B 385.6 389.0 — 389.0 — Revolver 694.6 694.6 — 694.6 — 2027 Senior Notes 592.9 624.0 — 624.0 — 2028 Senior Notes 494.4 501.3 — 501.3 — December 31, 2019 (in millions) Carrying Amount Fair Value Level 1 Level 2 Level 3 Financial assets: Restricted cash $ 46.3 $ 46.3 $ 46.3 $ — $ — Financial liabilities: Term Loan B 388.0 392.0 — 392.0 — 2027 Senior Notes 592.0 636.0 — 636.0 — 2028 Senior Notes 493.9 515.2 — 515.2 —

Commitments and Contingencies Disclosure [Abstract]
Contingencies	CONTINGENCIES We are 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. 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. 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. 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, 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.

We have aggregated the following businesses as well as certain corporate operations, and other immaterial joint ventures in "All Other" to reconcile to consolidated results: • Oak Grove • Newport • Turfway Park • Arlington • United Tote • Corporate We conduct our business through these reportable segments and report net revenue and operating expense associated with these reportable segments in the accompanying condensed consolidated statements of comprehensive income. 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 and disposition related charges; ◦ Calder racing exit costs; and ◦ Other transaction expense, including legal, accounting, and other deal-related expense; • Stock-based compensation expense; • Midwest Gaming's impact on our investments in unconsolidated affiliates from: ◦ The impact of changes in fair value of interest rate swaps; and ◦ Recapitalization and transaction costs; • Asset impairments; • Gain on Ocean Downs/Saratoga Transaction; • Legal reserves; • Pre-opening expense; and • Other charges, recoveries and expenses 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 condensed consolidated statements of comprehensive income.
