Organization, Consolidation and Presentation of Financial Statements [Abstract]
BASIS OF PRESENTATION AND SIGNIFICANT ACCOUNTING POLICIES	NOTE 1 - BASIS OF PRESENTATION AND SIGNIFICANT ACCOUNTING POLICIES Business, Consolidation and Presentation The accompanying unaudited condensed consolidated financial statements have been prepared in accordance with SEC rules and regulations and, in the opinion of management, include all adjustments (consisting of normal recurring adjustments) necessary to present fairly the financial position, results of operations, comprehensive income, cash flows and changes in equity for the periods presented. The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the amounts reported in the financial statements and accompanying notes. Management bases its estimates on various assumptions and historical experience, which are believed to be reasonable; however, due to the inherent nature of estimates, actual results may differ significantly due to changed conditions or assumptions. The results of operations for the three and six months ended June 30, 2022 are not necessarily indicative of results to be expected for the year ending December 31, 2022 or any other future period. These unaudited condensed consolidated financial statements should be read in conjunction with the financial statements and notes included in our Annual Report on Form 10-K for the year ended December 31, 2021 and in our Quarterly Report on Form 10-Q for the quarterly period ended March 31, 2022. Business Operations We are vertically integrated from mined raw materials, direct reduced iron and ferrous scrap to primary steelmaking and downstream finishing, stamping, tooling and tubing. We are organized into four operating segments based on differentiated products, Steelmaking, Tubular, Tooling and Stamping, and European Operations. We primarily operate through one reportable segment – the Steelmaking segment. Basis of Consolidation The unaudited condensed consolidated financial statements consolidate our accounts and the accounts of our wholly owned subsidiaries, all subsidiaries in which we have a controlling interest and VIEs for which we are the primary beneficiary. All intercompany transactions and balances are eliminated upon consolidation. Investments in Affiliates We have investments in several businesses accounted for using the equity method of accounting. As of June 30, 2022 and December 31, 2021, our investment in affiliates of $132 million and $128 million, respectively, was classified in Other non-current assets. Significant Accounting Policies A detailed description of our significant accounting policies can be found in the audited financial statements included in our Annual Report on Form 10-K for the year ended December 31, 2021 filed with the SEC. There have been no material changes in our significant accounting policies and estimates from those disclosed therein. Recent Accounting Pronouncements Issued and Adopted In August 2020, the FASB issued ASU 2020-06, Debt—Debt with Conversion and Other Options (Subtopic 470-20) and Derivatives and Hedging—Contracts in Entity’s Own Equity (Subtopic 815-40). This update requires certain convertible instruments to be accounted for as a single liability measured at its amortized cost. Additionally, the update requires the use of the "if-converted" method, removing the treasury stock method, when calculating diluted shares. We utilized the modified retrospective method of adoption; using this approach, the guidance was applied to transactions outstanding as of the beginning of the fiscal year in which the amendment was adopted. On January 18, 2022, we redeemed all of our outstanding 1.500% 2025 Convertible Senior Notes; therefore, there was a de minimis impact as a result of our adoption of this update.

Business Combinations [Abstract]
ACQUISITIONS	NOTE 3 - ACQUISITIONS FPT Acquisition Overview On November 18, 2021, pursuant to the FPT Acquisition Agreement, we completed the FPT Acquisition, in which we were the acquirer. The FPT Acquisition gives us a competitive advantage in sourcing prime scrap, a key raw material for our steelmaking facilities. We incurred acquisition-related costs, excluding severance costs, of $1 million for the six months ended June 30, 2022, which was recorded in Selling, general and administrative expenses on the Statements of Unaudited Condensed Consolidated Operations . The fair value of the total purchase consideration was determined as follows: (In Millions) Cash consideration: Cash consideration pursuant to the FPT Acquisition Agreement $ 778 Estimated cash consideration payable related to Internal Revenue Code Section 338(h)(10) 35 Total cash consideration 813 Fair value of settlement of a pre-existing relationship (20) Total purchase consideration $ 793 The Company's estimation of cash consideration payable related to Internal Revenue Code Section 338(h)(10) with respect to entities acquired in connection with the FPT Acquisition could potentially change as elections are expected to be finalized in the third quarter of 2022. Valuation Assumption and Purchase Price Allocation We estimated fair values at November 18, 2021 for the preliminary allocation of consideration to the net tangible and intangible assets acquired and liabilities assumed in connection with the FPT Acquisition. During the measurement period, we will continue to obtain information to assist in finalizing the fair value of assets acquired and liabilities assumed, which may differ materially from these preliminary estimates. If we determine any measurement period adjustments are material, we will apply those adjustments, including any related impacts to net income, in the reporting period in which the adjustments are determined. We are in the process of conducting a valuation of the assets acquired and liabilities assumed related to the FPT Acquisition, most notably, personal and real property, deferred taxes and environmental obligations, and the final allocation will be made when completed, including the result of any identified goodwill. Accordingly, the provisional measurements noted below are preliminary and subject to modification in the future. The preliminary purchase price allocation to assets acquired and liabilities assumed in the FPT Acquisition was: (In Millions) Initial Allocation of Consideration Measurement Period Adjustments Updated Allocation Cash and cash equivalents $ 9 $ — $ 9 Accounts receivable, net 233 2 235 Inventories 137 2 139 Other current assets 4 — 4 Property, plant and equipment 179 12 191 Other non-current assets 74 (10) 64 Accounts payable (122) — (122) Accrued employment costs (8) — (8) Other current liabilities (9) — (9) Other non-current liabilities (21) (1) (22) Net identifiable assets acquired 476 5 481 Goodwill 279 33 312 Total net assets acquired $ 755 $ 38 $ 793 The goodwill resulting from the FPT Acquisition primarily represents the incremental benefit of providing substantial access to prime scrap for our vertically integrated steelmaking business, as well as any synergistic benefits to be realized from the FPT Acquisition within our Steelmaking segment. The preliminary purchase price allocated to identifiable intangible assets acquired was: (In Millions) Weighted Average Life (In Years) Customer relationships $ 13 15 Supplier relationships 21 18 Trade names and trademarks 7 15 Total identifiable intangible assets $ 41 17 Intangible assets are classified as Other non-current assets on the Statements of Unaudited Condensed Consolidated Financial Position.

REVENUES

Revenue from Contract with Customer [Abstract]
REVENUES	NOTE 4 - REVENUES We generate our revenue through product sales, in which shipping terms indicate when we have fulfilled our performance obligations and transferred control of products to our customer. Our revenue transactions consist of a single performance obligation to transfer promised goods. Our contracts with customers define the mechanism for determining the sales price, which is generally fixed upon transfer of control, but the contracts generally do not impose a specific quantity on either party. Quantities to be delivered to the customer are determined at a point near the date of delivery through purchase orders or other written instructions we receive from the customer. Spot market sales are made through purchase orders or other written instructions. We consider our performance obligation to be complete and recognize revenue when control transfers in accordance with shipping terms. Revenue is measured as the amount of consideration we expect to receive in exchange for transferring product.

Segment Reporting [Abstract]
SEGMENT REPORTING	NOTE 5 - SEGMENT REPORTING We are vertically integrated from mined raw materials and direct reduced iron and ferrous scrap to primary steelmaking and downstream finishing, stamping, tooling and tubing. We are organized into four operating segments based on our differentiated products – Steelmaking, Tubular, Tooling and Stamping, and European Operations. We have one reportable segment – Steelmaking. The operating segment results of our Tubular, Tooling and Stamping, and European Operations that do not constitute reportable segments are combined and disclosed in the Other Businesses category. Our Steelmaking segment operates as the largest flat-rolled steel producer supported by being the largest iron ore pellet producer as well as a leading prime scrap processor in North America, primarily serving the automotive, distributors and converters, and infrastructure and manufacturing markets. Our Other Businesses primarily include the operating segments that provide customer solutions with carbon and stainless steel tubing products, advanced-engineered solutions, tool design and build, hot- and cold-stamped steel components, and complex assemblies. All intersegment transactions were eliminated in consolidation. We evaluate performance on an operating segment basis, as well as a consolidated basis, based on Adjusted EBITDA, which is a non-GAAP measure. This measure is used by management, investors, lenders and other external users of our financial statements to assess our operating performance and to compare operating performance to other companies in the steel industry. In addition, management believes Adjusted EBITDA is a useful measure to assess the earnings power of the business without the impact of capital structure and can be used to assess our ability to service debt and fund future capital expenditures in the business. Our results by segment are as follows: (In Millions) Three Months Ended Six Months Ended 2022 2021 2022 2021 Revenues: Steelmaking $ 6,176 $ 4,922 $ 11,970 $ 8,841 Other Businesses 161 123 322 253 Total revenues $ 6,337 $ 5,045 $ 12,292 $ 9,094 Adjusted EBITDA: Steelmaking $ 1,108 $ 1,360 $ 2,531 $ 1,862 Other Businesses 20 8 49 19 Eliminations 1 2 (8) 1 (8) Total Adjusted EBITDA $ 1,130 $ 1,360 $ 2,581 $ 1,873 1 In 2022, we began allocating Corporate SG&A to our operating segments.

Commitments and Contingencies Disclosure [Abstract]
COMMITMENTS AND CONTINGENCIES	NOTE 18 - COMMITMENTS AND CONTINGENCIES Purchase Commitments We purchase portions of the principal raw materials required for our steel manufacturing operations under annual and multi-year agreements, some of which have minimum quantity requirements. We also use large volumes of natural gas, electricity and industrial gases in our steel manufacturing operations. We negotiate most of our purchases of chrome, industrial gases and a portion of our electricity under multi-year agreements. Our purchases of coke are made under annual or multi-year agreements with periodic price adjustments. We typically purchase coal under annual fixed-price agreements. We also purchase certain transportation services under multi-year contracts with minimum quantity requirements. Contingencies We are currently the subject of, or party to, various claims and legal proceedings incidental to our current and historical operations. These claims and legal proceedings are subject to inherent uncertainties and unfavorable rulings could occur. An unfavorable ruling could include monetary damages, additional funding requirements or an injunction. If an unfavorable ruling were to occur, there exists the possibility of a material adverse effect on the financial position and results of operations for the period in which the ruling occurs or future periods. However, based on currently available information, we do not believe that any pending claims or legal proceedings will result in a material adverse effect in relation to our consolidated financial statements. Environmental Contingencies Although we believe our operating practices have been consistent with prevailing industry standards, hazardous materials may have been released at operating sites or third-party sites in the past, including operating sites that we no longer own. If we reasonably can, we estimate potential remediation expenditures for those sites where future remediation efforts are probable based on identified conditions, regulatory requirements or contractual obligations arising from the sale of a business or facility. For sites involving government-required investigations, we typically make an estimate of potential remediation expenditures only after the scope of remediation is determined or approved by the relevant environmental agencies. In general, the material factors in these estimates include the costs associated with investigations, delineations, risk assessments, remedial work, governmental response and oversight, site monitoring and preparation of reports to the appropriate environmental agencies. The following is a summary of our environmental obligations: (In Millions) June 30, December 31, Environmental obligations $ 140 $ 207 Less: current portion 17 20 Long-term environmental obligations $ 123 $ 187 The decrease in environmental obligations relates to a reclassification of $63 million from environmental to asset retirement obligations as of June 30, 2022. We cannot predict the ultimate costs for each site with certainty because of the evolving nature of the investigation and remediation process. Rather, to estimate the probable costs, we must make certain assumptions. The most significant of these assumptions is for the nature and scope of the work that will be necessary to investigate and remediate a particular site and the cost of that work. Other significant assumptions include the cleanup technology that will be used, whether and to what extent any other parties will participate in paying the investigation and remediation costs, reimbursement of past response costs and future oversight costs by governmental agencies, and the reaction of the governing environmental agencies to the proposed work plans. Costs for future investigation and remediation are not discounted to their present value, unless the amount and timing of the cash disbursements are readily known. To the extent that we have been able to reasonably estimate future liabilities, we do not believe that there is a reasonable possibility that we will incur a loss or losses that exceed the amounts we accrued for the environmental matters discussed below that would, either individually or in the aggregate, have a material adverse effect on our consolidated financial condition, results of operations or cash flows. However, since we recognize amounts in the consolidated financial statements in accordance with GAAP that exclude potential losses that are not probable or that may not be currently estimable, the ultimate costs of these environmental matters may be higher than the liabilities we currently have recorded in our consolidated financial statements. Pursuant to RCRA, which governs the treatment, handling and disposal of hazardous waste, the EPA and authorized state environmental agencies may conduct inspections of RCRA-regulated facilities to identify areas where there have been releases of hazardous waste or hazardous constituents into the environment and may order the facilities to take corrective action to remediate such releases. Likewise, the EPA or the states may require closure or post-closure care of residual, industrial and hazardous waste management units. Environmental regulators have the authority to inspect all of our facilities. While we cannot predict the future actions of these regulators, it is possible that they may identify conditions in future inspections of these facilities that they believe require corrective action. Pursuant to CERCLA, the EPA and state environmental authorities have conducted site investigations at some of our facilities and other third-party facilities, portions of which previously may have been used for disposal of materials that are currently regulated. The results of these investigations are still pending, and we could be directed to spend funds for remedial activities at the former disposal areas. Because of the uncertain status of these investigations, however, we cannot reasonably predict whether or when such spending might be required or its magnitude. On April 29, 2002, AK Steel entered a mutually agreed-upon administrative order with the consent of the EPA pursuant to Section 122 of CERCLA to perform a RI/FS of the Hamilton plant site located in New Miami, Ohio. The plant ceased operations in 1990 and all of its former structures have been demolished. AK Steel submitted the investigation portion of the RI/FS and completed supplemental studies. Until the RI/FS is complete, we cannot reasonably estimate the additional costs, if any, we may incur for potentially required remediation of the site or when we may incur them. Burns Harbor Water Issues In August 2019, ArcelorMittal Burns Harbor LLC (n/k/a Cleveland-Cliffs Burns Harbor LLC) suffered a loss of the blast furnace cooling water recycle system, which led to the discharge of cyanide and ammonia in excess of the Burns Harbor plant's NPDES permit limits. Since that time, the facility has taken numerous steps to prevent recurrence and maintain compliance with its NPDES permit. We engaged in settlement discussions with the U.S. Department of Justice, the EPA and the State of Indiana to resolve any alleged violations of environmental laws or regulations arising out of the August 2019 event. Later stages of the settlement discussions included the Environmental Law and Policy Center (ELPC) and Hoosier Environmental Council (HEC), which had filed a lawsuit on December 20, 2019 in the U.S. District Court for the Northern District of Indiana alleging violations resulting from the August 2019 event and other Clean Water Act claims. On February 14, 2022, the United States and the State of Indiana filed a complaint and a proposed consent decree, and on April 21, 2022, the United States, with the consent of all of the parties, filed a motion seeking final approval of the consent decree from the court. The consent decree was approved by the court with an effective date of May 6, 2022. The consent decree requires specified enhancements to the mill's wastewater treatment systems and payment of a $3 million civil penalty, along with other terms and conditions. Other parties to the consent decree include the United States, the State of Indiana, ELPC and HEC. The ELPC/HEC civil litigation was dismissed with prejudice on May 12, 2022. In addition, ArcelorMittal Burns Harbor LLC was served with a subpoena on December 5, 2019, from the United States District Court for the Northern District of Indiana, relating to the August 2019 event and has responded to the subpoena requests, including follow-up requests. With the resolution of monetary sanctions and injunctive relief requirements under the consent decree, we do not believe that the costs to resolve any other third-party claims, including potential natural resource damages claims, that may arise out of the August 2019 event are likely to have, individually or in the aggregate, a material adverse effect on our consolidated financial condition, results of operations or cash flows. In addition to the foregoing matters, we are or may be involved in proceedings with various regulatory authorities that may require us to pay fines, comply with more rigorous standards or other requirements, or incur capital and operating expenses for environmental compliance. We believe that the ultimate disposition of any such proceedings will not have, individually or in the aggregate, a material adverse effect on our consolidated financial condition, results of operations or cash flows. Tax Matters The calculation of our tax liabilities involves dealing with uncertainties in the application of complex tax regulations. We recognize liabilities for anticipated tax audit issues based on our estimate of whether, and the extent to which, additional taxes will be due. If we ultimately determine that payment of these amounts is unnecessary, we reverse the liability and recognize a tax benefit during the period in which we determine that the liability is no longer necessary. We also recognize tax benefits to the extent that it is more likely than not that our positions will be sustained when challenged by the taxing authorities. To the extent we prevail in matters for which liabilities have been established, or are required to pay amounts in excess of our liabilities, our effective tax rate in a given period could be materially affected. An unfavorable tax settlement would require use of our cash and result in an increase in our effective tax rate in the year of resolution. A favorable tax settlement would be recognized as a reduction in our effective tax rate in the year of resolution. Other Contingencies In addition to the matters discussed above, there are various pending and potential claims against us and our subsidiaries involving product liability, personal injury, commercial, employee benefits and other matters arising in the ordinary course of business. Because of the considerable uncertainties that exist for any claim, it is difficult to reliably or accurately estimate what the amount of a loss would be if a claimant prevails. If material assumptions or factual understandings we rely on to evaluate exposure for these contingencies prove to be inaccurate or otherwise change, we may be required to record a liability for an adverse outcome. If, however, we have reasonably evaluated potential future liabilities for all of these contingencies, including those described more specifically above, it is our opinion, unless we otherwise noted, that the ultimate liability from these contingencies, individually or in the aggregate, should not have a material adverse effect on our consolidated financial position, results of operations or cash flows.

All intercompany transactions and balances are eliminated upon consolidation.
Investment in Affiliates	Investments in Affiliates We have investments in several businesses accounted for using the equity method of accounting. As of June 30, 2022 and December 31, 2021, our investment in affiliates of $132 million and $128 million, respectively, was classified in Other non-current assets.
Recent Accounting Pronouncements	Recent Accounting Pronouncements Issued and Adopted In August 2020, the FASB issued ASU 2020-06, Debt—Debt with Conversion and Other Options (Subtopic 470-20) and Derivatives and Hedging—Contracts in Entity’s Own Equity (Subtopic 815-40). This update requires certain convertible instruments to be accounted for as a single liability measured at its amortized cost. Additionally, the update requires the use of the "if-converted" method, removing the treasury stock method, when calculating diluted shares. We utilized the modified retrospective method of adoption; using this approach, the guidance was applied to transactions outstanding as of the beginning of the fiscal year in which the amendment was adopted. On January 18, 2022, we redeemed all of our outstanding 1.500% 2025 Convertible Senior Notes; therefore, there was a de minimis impact as a result of our adoption of this update.
