Organization, Consolidation and Presentation of Financial Statements [Abstract]
Organization and Basis of Presentation	Organization and Basis of Presentation Delek US Holdings, Inc. operates through its consolidated subsidiaries, which include Delek US Energy, Inc. ("Delek Energy") (and its subsidiaries) and Alon USA Energy, Inc. ("Alon") (and its subsidiaries). The terms "we," "our," "us," "Delek" and the "Company" are used in this report to refer to Delek and its consolidated subsidiaries. Delek's common stock is listed on the New York Stock Exchange ("NYSE") under the symbol "DK." Our condensed consolidated financial statements include the accounts of Delek and its subsidiaries. Certain information and footnote disclosures normally included in annual financial statements prepared in accordance with United States ("U.S.") Generally Accepted Accounting Principles ("GAAP") have been condensed or omitted, although management believes that the disclosures herein are adequate to make the financial information presented not misleading. Our unaudited condensed consolidated financial statements have been prepared in conformity with GAAP applied on a consistent basis with those of the annual audited consolidated financial statements included in our Annual Report on Form 10-K filed with the Securities and Exchange Commission ("SEC") on February 26, 2025 (the "Annual Report on Form 10-K") and in accordance with the rules and regulations of the SEC. These unaudited condensed consolidated financial statements should be read in conjunction with the audited consolidated financial statements and the notes thereto for the year ended December 31, 2024 included in our Annual Report on Form 10-K. Our condensed consolidated financial statements include Delek Logistics Partners, LP ("Delek Logistics", NYSE:DKL), which is a variable interest entity ("VIE"). As the indirect owner of the general partner of Delek Logistics, we have the ability to direct the activities of this entity that most significantly impact its economic performance. We are also considered to be the primary beneficiary for accounting purposes for this entity and are Delek Logistics' primary customer. In the event that Delek Logistics incurs a loss, our operating results will reflect such loss, net of intercompany eliminations, to the extent of our ownership interest in this entity. On July 31, 2024, a wholly owned subsidiary of Delek, entered into a definitive equity purchase agreement (the "Retail Purchase Agreement") with a subsidiary of Fomento Económico Mexicano, S.A.B. de C.V. (“FEMSA”). Under the terms of the Retail Purchase Agreement, Delek agreed to sell, and FEMSA agreed to purchase, 100% of the equity interests in four of Delek’s wholly-owned subsidiaries that owned and operated 249 retail fuel and convenience stores (the "Retail Stores") under the Delek US Retail brand (the “Retail Transaction”). The Retail Transaction closed on September 30, 2024. As a result of the Retail Purchase Agreement, we met the requirements under the provisions of Accounting Standards Codification ("ASC") 205-20, Presentation of Financial Statements - Discontinued Operations ("ASC 205-20") and ASC 360, Property, Plant and Equipment ("ASC 360"), to report the results of the Retail Stores as discontinued operations and to classify the Retail Stores as a group of discontinued operations assets. On January 2, 2025, Delek Logistics completed the acquisition of 100% of the limited liability company interests in Gravity Water Intermediate Holdings LLC from Gravity Water Holdings LLC (the "Seller") related to the Seller's water disposal and recycling operations in the Permian Basin and the Bakken (the “Gravity Acquisition”). See Note 2 for further information. In the opinion of management, all adjustments necessary for a fair presentation of the financial condition and the results of operations for the interim periods have been included. All significant intercompany transactions and account balances have been eliminated in consolidation. All adjustments are of a normal, recurring nature. Operating results for the interim period should not be viewed as representative of results that may be expected for any future interim period or for the full year. Reclassifications Certain prior period amounts have been reclassified in order to conform to the current period presentation. Having classified the Retail Stores as discontinued operations, the condensed consolidated balance sheets for all periods presented have been reclassified to reflect discontinued operations assets and discontinued operations liabilities. The condensed consolidated statements of income for all periods presented have been reclassified to reflect the results of the Retail Stores as income from discontinued operations, net of taxes. See Note 4 for further information regarding discontinued operations.
