Description of Business [Abstract]
Description of Business	1. Description of Business Overview Icahn Enterprises L.P. (“Icahn Enterprises”) is a master limited partnership formed in Delaware on February 17, 1987. Icahn Enterprises Holdings L.P. (“Icahn Enterprises Holdings”) is a limited partnership formed in Delaware on February 17, 1987. References to “we,” “our” or “us” herein include both Icahn Enterprises and Icahn Enterprises Holdings and their subsidiaries, unless the context otherwise requires. Icahn Enterprises owns a 99% limited partner interest in Icahn Enterprises Holdings. Icahn Enterprises G.P. Inc. (“Icahn Enterprises GP”), which is owned and controlled by Mr. Carl C. Icahn, owns a 1% general partner interest in each of Icahn Enterprises and Icahn Enterprises Holdings as of June 30, 2021. Icahn Enterprises Holdings and its subsidiaries own substantially all of our assets and liabilities and conduct substantially all of our operations. Therefore, the financial results of Icahn Enterprises and Icahn Enterprises Holdings are substantially the same, with differences relating primarily to the allocation of the general partner interest, which is reflected as an aggregate 1.99% general partner interest in the financial statements of Icahn Enterprises. In addition to the above, Mr. Icahn and his affiliates owned approximately 90% of Icahn Enterprises’ outstanding depositary units as of June 30, 2021. Description of Continuing Operating Businesses We are a diversified holding company owning subsidiaries currently engaged in the following continuing operating businesses: Investment, Energy, Automotive, Food Packaging, Metals, Real Estate, Home Fashion and Pharma. We also report the results of our Holding Company, which includes the results of certain subsidiaries of Icahn Enterprises and Icahn Enterprises Holdings (unless otherwise noted), and investment activity and expenses associated with our Holding Company. See Note 12, “Segment Reporting,” for a reconciliation of each of our reporting segment’s results of operations to our consolidated results. Certain additional information with respect to our segments is discussed below. Investment Our Investment segment is comprised of various private investment funds (“Investment Funds”) in which we have general partner interests and through which we invest our proprietary capital. As general partner, we provide investment advisory and certain administrative and back-office services to the Investment Funds but do not provide such services to any other entities, individuals or accounts. We and certain of Mr. Icahn’s family members and affiliates are the only investors in the Investment Funds. Interests in the Investment Funds are not offered to outside investors. We had interests in the Investment Funds with a fair value of approximately $4.7 billion and $4.3 billion as of June 30, 2021 and December 31, 2020, respectively. Energy We conduct our Energy segment through our majority owned subsidiary, CVR Energy, Inc. (“CVR Energy”).

Accounting Policies [Abstract]
Basis of Presentation and Summary of Significant Accounting Policies	2. Basis of Presentation and Summary of Significant Accounting Policies We conduct and plan to continue to conduct our activities in such a manner as not to be deemed an investment company under the Investment Company Act of 1940, as amended (the “Investment Company Act”). Therefore, no more than 40% of our total assets can be invested in investment securities, as such term is defined in the Investment Company Act. In addition, we do not invest or intend to invest in securities as our primary business. We intend to structure our investments to continue to be taxed as a partnership rather than as a corporation under the applicable publicly traded partnership rules of the Internal Revenue Code, as amended. Events beyond our control, including significant appreciation or depreciation in the market value of certain of our publicly traded holdings or adverse developments with respect to our ownership of certain of our subsidiaries, could result in our inadvertently becoming an investment company that is required to register under the Investment Company Act. Our sales of Federal-Mogul LLC, Tropicana Entertainment Inc., American Railcar Industries, Inc. and Ferrous Resources Ltd. in recent years did not result in our being considered an investment company. However, additional transactions involving the sale of certain assets could result in our being considered an investment company. Following such events or transactions, an exemption under the Investment Company Act would provide us up to one year to take steps to avoid becoming classified as an investment company. We expect to take steps to avoid becoming classified as an investment company, but no assurance can be made that we will successfully be able to take the steps necessary to avoid becoming classified as an investment company. The accompanying condensed consolidated financial statements and related notes should be read in conjunction with our consolidated financial statements and related notes contained in our Annual Report on Form 10-K for the year ended December 31, 2020. The condensed consolidated financial statements have been prepared in accordance with the rules and regulations of the Securities and Exchange Commission (the “SEC”) related to interim financial statements. Certain information and footnote disclosures normally included in financial statements prepared in accordance with accounting principles generally accepted in the United States (“U.S. GAAP”) have been condensed or omitted pursuant to such rules and regulations. The financial information contained herein is unaudited; however, management believes all adjustments have been made that are necessary to present fairly the results for the interim periods. All such adjustments are of a normal and recurring nature. Principles of Consolidation Our condensed consolidated financial statements include the accounts of (i) Icahn Enterprises and Icahn Enterprises Holdings and (ii) the wholly and majority owned subsidiaries of Icahn Enterprises and Icahn Enterprises Holdings, in addition to variable interest entities (“VIEs”) in which we are the primary beneficiary. In evaluating whether we have a controlling financial interest in entities that we consolidate, we consider the following: (1) for voting interest entities, including limited partnerships and similar entities that are not VIEs, we consolidate these entities in which we own a majority of the voting interests; and (2) for VIEs, we consolidate these entities in which we are the primary beneficiary. See below for a discussion of our VIEs. Kick-out rights, which are the rights underlying the limited partners’ ability to dissolve the limited partnership or otherwise remove the general partners, held through voting interests of partnerships and similar entities that are not VIEs are considered the equivalent of the equity interests of corporations that are not VIEs. Except for our Investment segment and Holding Company, for equity investments in which we own 50% or less but greater than 20%, we generally account for such investments using the equity method. All other equity investments are accounted for at fair value. Reclassifications Certain reclassifications from the prior year presentation have been made to conform to the current year presentation, which did not have an impact on previously reported net income and equity and are not deemed material. Consolidated Variable Interest Entities The following is a discussion of variable interest entities in which we are deemed to be the primary beneficiary and we therefore consolidate. Icahn Enterprises Holdings We determined that Icahn Enterprises Holdings is a VIE because it is a limited partnership that lacks both substantive kick-out and participating rights. Although Icahn Enterprises is not the general partner of Icahn Enterprises Holdings, Icahn Enterprises is deemed to be the primary beneficiary of Icahn Enterprises Holdings principally based on its 99% limited partner interest in Icahn Enterprises Holdings, as well as our related party relationship with the general partner, and therefore continues to consolidate Icahn Enterprises Holdings. The condensed consolidated financial statements of Icahn Enterprises Holdings are included in this Report. The balances with respect to Icahn Enterprises Holdings’ consolidated VIEs are discussed below, comprising the Investment Funds, CVR Partners and Viskase’s joint venture. Investment We determined that each of the Investment Funds are considered VIEs because these limited partnerships lack both substantive kick-out and participating rights. Because we have a general partner interest in each of the Investment Funds and have significant limited partner interests in each of the Investment Funds, coupled with our significant exposure to losses and benefits in each of the Investment Funds, we are the primary beneficiary of each of the Investment Funds and therefore continue to consolidate each of the Investment Funds. Energy CVR Partners is considered a VIE because it is a limited partnership that lacks both substantive kick-out and participating rights. In addition, CVR Energy also concluded that, based upon its general partner’s roles and rights in CVR Partners as afforded by CVR Partners’ partnership agreement, coupled with its exposure to losses and benefits in CVR Partners through its significant limited partner interest, intercompany credit facilities and services agreements, it is the primary beneficiary of CVR Partners. Food Packaging Viskase holds a variable interest in a joint venture for which Viskase is the primary beneficiary. Viskase’s interest in the joint venture includes a 50% equity interest and also relates to the sales, operations, administrative and financial support to the joint venture through providing many of the assets used in its business. ​ The following table includes balances of assets and liabilities of VIE’s included in Icahn Enterprises Holdings’ condensed consolidated balance sheets. ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ June 30, ​ December 31, ​ 2021 2020 ​ ​ (in millions) Cash and cash equivalents ​ $ 49 ​ $ 31 Cash held at consolidated affiliated partnerships and restricted cash ​ 1,218 ​ 1,558 Investments ​ 10,603 ​ 8,239 Due from brokers ​ 4,358 ​ 3,437 Accounts receivable, net ​ ​ 35 ​ ​ 37 Inventories, net ​ 50 ​ 42 Property, plant and equipment, net ​ 1,007 ​ 1,042 Unrealized gain on derivative contracts ​ ​ 679 ​ ​ 785 Intangible assets, net ​ 222 ​ 232 Other assets ​ 59 ​ 107 Accounts payable ​ 30 ​ 25 Accrued expenses and other liabilities ​ ​ 82 ​ ​ 70 Deferred tax liabilities ​ ​ 1 ​ ​ 1 Unrealized loss on derivative contracts ​ ​ 728 ​ ​ 622 Securities sold, not yet purchased, at fair value ​ 4,231 ​ 2,521 Due to brokers ​ 1,528 ​ 1,618 Debt ​ 640 ​ 636 ​ Fair Value of Financial Instruments The carrying values of cash and cash equivalents, cash held at consolidated affiliated partnerships and restricted cash, accounts receivable, due from brokers, accounts payable, accrued expenses and other liabilities and due to brokers are deemed to be reasonable estimates of their fair values because of their short-term nature. See Note 4, “Investments,” and Note 5, “Fair Value Measurements,” for a detailed discussion of our investments and other non-financial assets and/or liabilities. The fair value of our long-term debt is based on the quoted market prices for the same or similar issues or on the current rates offered to us for debt of the same remaining maturities. The carrying value and estimated fair value of our long-term debt as of June 30, 2021 was approximately $8.1 billion and $8.2 billion, respectively. The carrying value and estimated fair value of our long-term debt as of December 31, 2020 was approximately $8.1 billion and $8.2 billion, respectively. Cash Flow Cash and cash equivalents and restricted cash and restricted cash equivalents on our condensed consolidated statements of cash flows is comprised of (i) cash and cash equivalents and (ii) cash held at consolidated affiliated partnerships and restricted cash. Cash Held at Consolidated Affiliated Partnerships and Restricted Cash Our cash held at consolidated affiliated partnerships balance was $223 million and $686 million as of June 30, 2021 and December 31, 2020, respectively. Cash held at consolidated affiliated partnerships relates to our Investment segment and consists of cash and cash equivalents held by the Investment Funds that, although not legally restricted, are not available to fund the general liquidity needs of the Investment segment or Icahn Enterprises. Our restricted cash balance was $1,046 million and $926 million as of June 30, 2021 and December 31, 2020, respectively. Restricted cash primarily relates to our Investment segment’s cash pledged and held for margin requirements on derivative transactions. Revenue From Contracts With Customers and Contract Balances Due to the nature of our business, we derive revenue from various sources in various industries. With the exception of all of our Investment segment’s and our Holding Company’s revenues, and our Real Estate segment’s leasing revenue, our revenue is generally derived from contracts with customers in accordance with U.S. GAAP. Such revenue from contracts with customers is included in net sales and other revenues from operations in the condensed consolidated statements of operations, however, our Real Estate segment’s leasing revenue, as disclosed in Note 9, “Leases,” is also included in other revenues from operations. Related contract assets are included in accounts receivable, net or other assets and related contract liabilities are included in accrued expenses and other liabilities in the condensed consolidated balance sheets. Our disaggregation of revenue information includes our net sales and other revenues from operations for each of our reporting segments as well as additional disaggregation of revenue information for our Energy and Automotive segments. See Note 12, “Segment Reporting,” for our complete disaggregation of revenue information. In addition, we disclose additional information with respect to revenue from contracts with customers and contract balances for our Energy and Automotive segments below. Energy Our Energy segment’s deferred revenue is a contract liability that primarily relates to fertilizer sales contracts requiring customer prepayment prior to product delivery to guarantee a price and supply of nitrogen fertilizer. Deferred revenue is recorded at the point in time in which a prepaid contract is legally enforceable and the associated right to consideration is unconditional prior to transferring product to the customer. An associated receivable is recorded for uncollected prepaid contract amounts. Contracts requiring prepayment are generally short-term in nature and revenue is recognized at the point in time in which the customer obtains control of the product. Our Energy segment had deferred revenue of $16 million and $31 million as of June 30, 2021 and December 31, 2020, respectively. For the six months ended June 30, 2021 and 2020, our Energy segment recorded revenue of $30 million and $27 million, respectively, with respect to deferred revenue outstanding as of the beginning of each respective period, which includes $22 million and $21 million recognized during the three months ended June 30, 2021 and 2020, respectively. As of June 30, 2021, our Energy segment had $6 million of remaining performance obligations for contracts with an original expected duration of more than one year. Our Energy segment expects to recognize approximately $3 million of these performance obligations as revenue by the end of 2021 and the remaining balance thereafter. Automotive Our Automotive segment has deferred revenue with respect to extended warranty plans of $41 million at each of June 30, 2021 and December 31, 2020, which are included in accrued expenses and other liabilities on the condensed consolidated balance sheets. For the six months ended June 30, 2021 and 2020, our Automotive segment recorded revenue of $12 million and $13 million, respectively, with respect to deferred revenue outstanding as of the beginning of each respective period, which includes $6 million and $7 million recognized during the three months ended June 30, 2021 and 2020, respectively. Adoption of New Accounting Standards In December 2019, the Financial Account Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) 2019-12, Simplifying the Accounting for Income Taxes Income Taxes standard and modifies other areas of the standard to clarify the application of U.S. GAAP. This ASU is effective for fiscal years beginning after December 15, 2020, and interim periods within those fiscal years. We have adopted this standard on January 1, 2021. Certain amendments in this ASU are applied using a retrospective approach and others using the prospective approach. The adoption of this standard did not have a significant impact on our condensed consolidated financial statements. Recently Issued Accounting Standards In March 2020, the FASB issued ASU 2020-04, Facilitation of the Effects of Reference Rate Reform on Financial Reporting Reference Rate Reform

Related Party Transactions [Abstract]
Related Party Transactions	3. Related Party Transactions Our second amended and restated agreement of limited partnership expressly permits us to enter into transactions with our general partner or any of its affiliates, including buying or selling properties from or to our general partner and any of its affiliates and borrowing and lending money from or to our general partner and any of its affiliates, subject to limitations contained in our partnership agreement and the Delaware Revised Uniform Limited Partnership Act. The indentures governing our indebtedness contain certain covenants applicable to transactions with affiliates. Investment Funds During the six months ended June 30, 2020, Mr. Icahn and his affiliates (excluding us) contributed $1,241 million to the Investment Funds consisting primarily of in-kind investments previously held directly by Mr. Icahn and his affiliates (excluding us). As of June 30, 2021 and December 31, 2020, the total fair market value of investments in the Investment Funds made by Mr. Icahn and his affiliates (excluding us) was approximately $5.6 billion and $5.0 billion, respectively, representing approximately 54% and 54% of the Investment Funds’ assets under management as of each respective date. We pay for expenses pertaining to the operation, administration and investment activities of our Investment segment for the benefit of the Investment Funds (including salaries, benefits and rent). Based on an expense-sharing arrangement, certain expenses borne by us are reimbursed by the Investment Funds. For the three months ended June 30, 2021 and 2020, $4 million and $3 million, respectively, was allocated to the Investment Funds based on this expense-sharing arrangement and for the six months ended June 30, 2021 and 2020, such allocation was $8 million and $(3) million, respectively. For the six months ended June 30, 2020, the allocation was reduced by $8 million relating to certain compensation arrangements. Hertz Global Holdings, Inc. and 767 Auto Leasing LLC The Investment Funds had an investment in the common stock of Hertz Global Holdings, Inc. (“Hertz”) measured at fair value that would have otherwise been subject to the equity method of accounting (until sold in the second quarter of 2020). Icahn Automotive provides services to Hertz in the ordinary course of business. Revenue from Hertz was $6 million and $20 million for the three and six months ended June 30, 2020, respectively. In addition to our transactions with Hertz disclosed above, in January 2018, we entered into a Master Motor Vehicle Lease and Management Agreement with Hertz, pursuant to which Hertz granted 767 Leasing the option to acquire certain vehicles from Hertz at rates aligned with the rates at which Hertz sells vehicles to third parties. Under this agreement, as amended, Hertz will lease the vehicles that 767 Leasing purchases from Hertz, or from third parties, under a mutually developed fleet plan and Hertz will manage, service, repair, sell and maintain those leased vehicles on behalf of 767 Leasing. Additionally, Hertz will rent the leased vehicles to transportation network company drivers from rental counters within locations leased or owned by us. This agreement had an initial term of 18 months and is subject to automatic six-month renewals thereafter, unless terminated by either party (with or without cause) prior to the start of any such six-month renewal. Our agreement with Hertz was unanimously approved by the independent directors of Icahn Enterprises’ audit committee. Due to the nature of our involvement with 767 Leasing, which includes Icahn Enterprises and Icahn Enterprises Holdings guaranteeing the payment obligations of 767 Leasing and sharing in the profits of 767 Leasing with Hertz, we determined that 767 Leasing is a variable interest entity. Furthermore, we determined that we are not the primary beneficiary as we do not have the power to direct the activities of 767 Leasing that most significantly impact its economic performance. Therefore, we do not consolidate the results of 767 Leasing. Our exposure to loss with respect to 767 Leasing is primarily limited to our direct investment in 767 Leasing as well as any payment obligations of 767 Leasing that we guarantee, which are not material as of June 30, 2021 and December 31, 2020. For the three and six months ended June 30, 2021, 767 Leasing distributed $5 million and $16 million, respectively, to us. As of June 30, 2021 and December 31, 2020, we had an equity method investment in 767 Leasing of $19 million and $40 million, respectively, which we report in our Automotive segment. Other Related Party Agreements On October 1, 2020, we entered into a manager agreement with Brett Icahn, the son of Carl C. Icahn, and affiliates of Brett Icahn. Under the manager agreement, Brett Icahn serves as the portfolio manager of a designated portfolio of assets within the Investment Funds over a seven-year term, subject to veto rights by our Investment segment and Carl C. Icahn. Additionally, Brett Icahn provides certain other services, at our request, which may entail research, analysis and advice with respect to a separate designated portfolio of assets within the Investment Funds. Subject to the terms of the manager agreement, at the end of the seven-year term, Brett Icahn will be entitled to receive a one-time lump sum payment as described in and computed pursuant to the manager agreement. Brett Icahn will not be entitled to receive from us any other compensation (including any salary or bonus) in respect of the services he is to provide under the manager agreement other than restricted depositary units granted under a restricted unit agreement, as discussed below. In accordance with the manager agreement, Brett Icahn will co-invest with the Investment Funds in certain positions, will make cash contributions to the Investment Funds in order to fund such co-investments and will have a special limited partnership interest in the Investment Funds through which the profit and loss attributable to such co-investments will be allocated to him. During 2021, Brett Icahn contributed $46 million in accordance with the manager agreement and has investments in the Investment Funds with a total fair market value of $65 million as of June 30, 2021. We also entered into a guaranty agreement with an affiliate of Brett Icahn, pursuant to which we guaranteed the payment of certain amounts required to be distributed by the Investment Funds to such affiliate pursuant to the terms and conditions of the manager agreement.

Fair Value Disclosures [Abstract]
Fair Value Measurements	5. Fair Value Measurements U.S. GAAP requires enhanced disclosures about assets and liabilities that are measured and reported at fair value and has established a hierarchal disclosure framework that prioritizes and ranks the level of market price observability used in measuring assets and liabilities at fair value. Market price observability is impacted by a number of factors, including the type of, and the characteristics specific to, the assets and liabilities. Assets and liabilities with readily available active quoted prices or for which fair value can be measured from actively quoted prices generally will have a higher degree of market price observability and a lesser degree of judgment used in measuring fair value. Assets and liabilities measured and reported at fair value are classified and disclosed in one of the following categories: Level 1 - Quoted prices are available in active markets for identical assets and liabilities as of the reporting date. Level 2 - Pricing inputs are other than quoted prices in active markets, which are either directly or indirectly observable as of the reporting date, and fair value is determined through the use of models or other valuation methodologies where all significant inputs are observable. The inputs and assumptions of our Level 2 assets and liabilities are derived from market observable sources including reported trades, broker/dealer quotes and other pertinent data. Level 3 - Pricing inputs are unobservable for the assets and liabilities and include situations where there is little, if any, market activity for the assets and liabilities. The inputs into the determination of fair value require significant management judgment or estimation. Fair value is determined using comparable market transactions and other valuation methodologies, adjusted as appropriate for liquidity, credit, market and/or other risk factors. In certain cases, the inputs used to measure fair value may fall into different levels of the fair value hierarchy. In such cases, the level within the fair value hierarchy is based on the lowest level of input that is significant to the fair value measurement. Our assessment of the significance of a particular input to the fair value measurement in its entirety requires judgment and consideration of factors specific to the assets and liabilities. Significant transfers, if any, between the levels within the fair value hierarchy are recognized at the beginning of the reporting period when changes in circumstances require such transfers. Assets and Liabilities Measured at Fair Value on a Recurring Basis The following table summarizes the valuation of our assets and liabilities by the above fair value hierarchy levels measured on a recurring basis: ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ June 30, 2021 ​ December 31, 2020 ​ Level 1 Level 2 Level 3 Total Level 1 Level 2 Level 3 Total ​ ​ (in millions) Assets ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Investments (Note 4) ​ $ 10,616 ​ $ 115 ​ $ 42 ​ $ 10,773 ​ $ 8,546 ​ $ 174 ​ $ 41 ​ $ 8,761 Derivative assets, net (Note 6) ​ — ​ 683 ​ — ​ 683 ​ — ​ 785 ​ — ​ 785 ​ ​ $ 10,616 ​ $ 798 ​ $ 42 ​ $ 11,456 ​ $ 8,546 ​ $ 959 ​ $ 41 ​ $ 9,546 Liabilities ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Securities sold, not yet purchased (Note 4) ​ $ 4,231 ​ $ — ​ $ — ​ $ 4,231 ​ $ 2,521 ​ $ — ​ $ — ​ $ 2,521 Derivative liabilities, net (Note 6) ​ — ​ 754 ​ — ​ 754 ​ 11 ​ 628 ​ — ​ 639 Other liabilities ​ — ​ 485 ​ — ​ 485 ​ — ​ 214 ​ — ​ 214 ​ ​ $ 4,231 ​ $ 1,239 ​ $ — ​ $ 5,470 ​ $ 2,532 ​ $ 842 ​ $ — ​ $ 3,374 ​ Our Level 3 investments increased $1 million during the six months ended June 30, 2021 due to purchases of investments.

Derivative Instruments and Hedging Activities Disclosure [Abstract]
Financial Instruments	6. Financial Instruments Overview Investment In the normal course of business, the Investment Funds may trade various financial instruments and enter into certain investment activities, which may give rise to off-balance-sheet risks, with the objective of capital appreciation or as economic hedges against other securities or the market as a whole. The Investment Funds’ investments may include futures, options, swaps and securities sold, not yet purchased. These financial instruments represent future commitments to purchase or sell other financial instruments or to exchange an amount of cash based on the change in an underlying instrument at specific terms at specified future dates. Risks arise with these financial instruments from potential counterparty non-performance and from changes in the market values of underlying instruments. Credit concentrations may arise from investment activities and may be impacted by changes in economic, industry or political factors. The Investment Funds routinely execute transactions with counterparties in the financial services industry, resulting in credit concentration with respect to the financial services industry. In the ordinary course of business, the Investment Funds may also be subject to a concentration of credit risk to a particular counterparty. The Investment Funds seek to mitigate these risks by actively monitoring exposures, collateral requirements and the creditworthiness of its counterparties. The Investment Funds have entered into various types of swap contracts with other counterparties. These agreements provide that they are entitled to receive or are obligated to pay in cash an amount equal to the increase or decrease, respectively, in the value of the underlying shares, debt and other instruments that are the subject of the contracts, during the period from inception of the applicable agreement to its expiration. In addition, pursuant to the terms of such agreements, they are entitled to receive or obligated to pay other amounts, including interest, dividends and other distributions made in respect of the underlying shares, debt and other instruments during the specified time frame. They are also required to pay to the counterparty a floating interest rate equal to the product of the notional amount multiplied by an agreed-upon rate, and they receive interest on any cash collateral that they post to the counterparty at the federal funds or LIBOR rate in effect for such period. The Investment Funds may trade futures contracts. A futures contract is a firm commitment to buy or sell a specified quantity of a standardized amount of a deliverable grade commodity, security, currency or cash at a specified price and specified future date unless the contract is closed before the delivery date. Payments (or variation margin) are made or received by the Investment Funds each day, depending on the daily fluctuations in the value of the contract, and the whole value change is recorded as an unrealized gain or loss by the Investment Funds. When the contract is closed, the Investment Funds record a realized gain or loss equal to the difference between the value of the contract at the time it was opened and the value at the time it was closed. The Investment Funds may utilize forward contracts to seek to protect their assets denominated in foreign currencies and precious metals holdings from losses due to fluctuations in foreign exchange rates and spot rates. The Investment Funds’ exposure to credit risk associated with non-performance of such forward contracts is limited to the unrealized gains or losses inherent in such contracts, which are recognized in other assets and accrued expenses and other liabilities in our condensed consolidated balance sheets. The Investment Funds may also enter into foreign currency contracts for purposes other than hedging denominated securities. When entering into a foreign currency forward contract, the Investment Funds agree to receive or deliver a fixed quantity of foreign currency for an agreed-upon price on an agreed-upon future date unless the contract is closed before such date. The Investment Funds record unrealized gains or losses on the contracts as measured by the difference between the forward foreign exchange rates at the dates of entry into such contracts and the forward rates at the reporting date. The Investment Funds may also purchase and write option contracts. As a writer of option contracts, the Investment Funds receive a premium at the outset and then bear the market risk of unfavorable changes in the price of the underlying financial instrument. As a result of writing option contracts, the Investment Funds are obligated to purchase or sell, at the holder’s option, the underlying financial instrument. Accordingly, these transactions result in off-balance-sheet risk, as the Investment Funds’ satisfaction of the obligations may exceed the amount recognized in our condensed consolidated balance sheets. Certain terms of the Investment Funds’ contracts with derivative counterparties, which are standard and customary to such contracts, contain certain triggering events that would give the counterparties the right to terminate the derivative instruments. In such events, the counterparties to the derivative instruments could request immediate payment on derivative instruments in net liability positions. The aggregate fair value of all of the Investment Funds’ derivative instruments with credit-risk-related contingent features that are in a liability position as of June 30, 2021 and December 31, 2020 was $0 million and $1 million, respectively. ​ The following table summarizes the volume of our Investment segment’s derivative activities based on their notional exposure, categorized by primary underlying risk: ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ June 30, 2021 ​ December 31, 2020 ​ Long Notional Exposure Short Notional Exposure Long Notional Exposure Short Notional Exposure ​ ​ ​ (in millions) Primary underlying risk: ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Equity contracts ​ $ 596 ​ $ 4,400 ​ $ — ​ $ 8,623 Credit contracts (1) ​ 1 ​ 2,027 ​ ​ — ​ 2,099 (1) The short notional amount on our credit default swap positions was approximately $6.5 billion at June 30, 2021. However, because credit spreads cannot compress below zero , our downside short notional exposure to loss is approximately $2.0 billion as of June 30, 2021. The short notional amount on our credit default swap positions was approximately $6.3 billion as of December 31, 2020. However, because credit spreads cannot compress below zero , our downside short notional exposure to loss is approximately $2.1 billion as of December 31, 2020. Certain derivative contracts executed by each of the Investment Funds with a single counterparty are reported on a net-by-counterparty basis where a legal right of offset exists under an enforceable netting agreement. Values for the derivative financial instruments, principally swaps, forwards, over-the-counter options and other conditional and exchange contracts, are reported on a net-by-counterparty basis. The following table presents the fair values of our Investment segment’s derivatives that are not designated as hedging instruments in accordance with U.S. GAAP: ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Derivative Assets ​ Derivative Liabilities ​ June 30, 2021 December 31, 2020 June 30, 2021 December 31, 2020 ​ ​ ​ (in millions) Equity contracts ​ $ 13 ​ $ 4 ​ $ 1,085 ​ $ 852 Credit contracts ​ 1,023 ​ 1,012 ​ — ​ 1 Sub-total ​ 1,036 ​ 1,016 ​ 1,085 ​ 853 Netting across contract types (1) ​ (357) ​ (231) ​ (357) ​ (231) Total (1) ​ $ 679 ​ $ 785 ​ $ 728 ​ $ 622 (1) Excludes netting of cash collateral received and posted.

Energy CVR Energy’s businesses are subject to price fluctuations caused by supply conditions, weather, economic conditions, interest rate fluctuations and other factors. To manage price risk on crude oil and other inventories and to fix margins on certain future production, CVR Refining regularly enters into various commodity derivative transactions. CVR Refining holds derivative instruments, such as exchange-traded crude oil futures and over-the-counter forward swap agreements, which it believes provide an economic hedge on future transactions, but such instruments are not designated as hedge instruments. CVR Refining may enter into forward purchase or sale contracts associated with renewable identification numbers (“RINs”). As of June 30, 2021 and December 31, 2020, CVR Refining had 6 million and 7 million, respectively, outstanding commodity swap positions. As of June 30, 2021 and December 31, 2020, CVR Refining had open forward purchase and sale commitments for 2 million barrels and 6 million barrels, respectively. As of June 30, 2021 and December 31, 2020, CVR Refining had open fixed-price commitments to purchase a net 21 million and 13 million RINs, respectively. Certain derivative contracts executed by our Energy segment with a single counterparty are reported on a net-by-counterparty basis where a legal right of offset exists under an enforceable netting agreement. As of June 30, 2021, our Energy segment had net asset derivatives of $4 million and net liability derivatives of $26 million and as of December 31, 2020, our Energy segment had net liability derivatives of $17 million. (Losses) gains recognized on derivatives for our Energy segment were $(2) million and $20 million for the three months ended June 30, 2021 and 2020, respectively, and $(34) million and $65 million for the six months ended June 30, 2021 and 2020, respectively.

(together the “Issuers”) issued $750 million in aggregate principal amount of 4.375% senior unsecured notes due 2029 (the “New 2029 Notes”). The New 2029 Notes are guaranteed by Icahn Enterprises Holdings (the “Guarantor”). The proceeds from the New 2029 Notes were used to redeem $750 million principal amount of 6.250% senior unsecured notes due 2022, and to pay accrued interest, related fees and expenses. Interest on the New 2029 Notes is payable semi-annually. In connection with this transaction, our Holding Company recorded a gain on extinguishment of debt of $2 million. The New 2029 Notes and the related guarantee are the senior unsecured obligations of the Issuers and rank equally with all of the Issuers’ and the Guarantor’s existing and future senior unsecured indebtedness and senior to all of the Issuers’ and the Guarantor’s existing and future subordinated indebtedness. The New 2029 Notes and the related guarantees are effectively subordinated to the Issuers’ and the Guarantor’s existing and future secured indebtedness to the extent of the collateral securing such indebtedness. The New 2029 Notes and the related guarantees are also effectively subordinated to all indebtedness and other liabilities of the Issuers’ subsidiaries other than the Guarantor. The indenture governing the New 2029 Notes restricts the payment of cash distributions, the purchase of equity interests or the purchase, redemption, defeasance or acquisition of debt subordinated to the senior unsecured notes. The indenture also restricts the incurrence of debt or the issuance of disqualified stock, as defined in the indenture, with certain exceptions. In addition, the indenture requires that on each quarterly determination date, Icahn Enterprises and the guarantor of the New 2029 Notes (currently only Icahn Enterprises Holdings) maintain certain minimum financial ratios, as defined therein. The indenture also restricts the creation of liens, mergers, consolidations and sales of substantially all of our assets, and transactions with affiliates. In April 2021, the Issuers issued $455 million in aggregate principal amount of additional 5.250% senior unsecured notes due 2027. The proceeds from this issuance were used to redeem the remaining $455 million principal amount of 6.250% senior unsecured notes due 2022, and to pay accrued interest, related fees and expenses. Energy In June 2021, CVR Partners issued $550 million in aggregate principal amount of 6.125% senior secured notes due 2028. Proceeds from these notes were used to fund a partial redemption of its existing 9.25% senior secured notes due 2023. These senior secured notes issued by CVR Partners are guaranteed on a senior secured basis by all of CVR Partners’ existing domestic subsidiaries, excluding CVR Nitrogen Finance Corporation. The indenture governing these notes contain certain covenants that restrict the ability of the issuers and their restricted subsidiaries from incurring additional debt or issuing certain disqualified equity, create liens on certain assets to secure debt, pay dividends/distributions or make other equity distributions, purchase or redeem capital stock/common units, make certain investments, transfer and sell assets, agree to certain restrictions on the ability of restricted subsidiaries to make distributions, loans, or other asset transfers to the issuers, consolidate, merge, sell, or otherwise dispose of all or substantially all of their assets, engage in transactions with affiliates and designate restricted subsidiaries as unrestricted subsidiaries. Covenants All of our subsidiaries are currently in compliance with all covenants and restrictions as described in the various executed agreements and contracts with respect to each debt instrument. These covenants include limitations on indebtedness, liens, investments, acquisitions, asset sales, dividends and other restricted payments and affiliate and extraordinary transactions. Non-Cash Charges to Interest Expense The amortization of deferred financing costs and debt discounts and premiums included in interest expense in the condensed consolidated statements of operations were zero and $1 million for the three months ended June 30, 2021 and 2020, respectively, and $1 million and $2 million for the six months ended June 30, 2021 and 2020, respectively.

Segment Reporting [Abstract]
Segment Reporting	12. Segment Reporting We report segment information based on the various industries in which our businesses operate and how we manage those businesses in accordance with our investment strategies, which may include: identifying and acquiring undervalued assets and businesses, often through the purchase of distressed securities; increasing value through management, financial or other operational changes; and managing complex legal, regulatory or financial issues, which may include bankruptcy or insolvency, environmental, zoning, permitting and licensing issues. Therefore, although many of our businesses are operated under separate local management, certain of our businesses are grouped together when they operate within a similar industry, comprising similarities in products, customers, production processes and regulatory environments, and when such businesses, when considered together, may be managed in accordance with one or more investment strategies specific to those businesses. Among other measures, we assess and measure segment operating results based on net income from continuing operations attributable to Icahn Enterprises and Icahn Enterprises Holdings. Certain terms of financings for certain of our businesses impose restrictions on the business’ ability to transfer funds to us, including restrictions on dividends, distributions, loans and other transactions. Condensed Statements of Operations Icahn Enterprises’ condensed statements of operations by reporting segment are presented below. Icahn Enterprises Holdings’ condensed statements of operations are substantially the same, with immaterial differences relating to our Holding Company’s interest expense. ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​

Income Tax Disclosure [Abstract]
Income Taxes	13. Income Taxes For the three months ended June 30, 2021, we recorded an income tax expense of $59 million on pre-tax loss of $3 million compared to an income tax expense of $128 million on pre-tax income of $992 million for the three months ended June 30, 2020. Our effective income tax rate was (1,966.7)% and 12.9% for the three months ended June 30, 2021 and 2020, respectively. For the three months ended June 30, 2021, the effective tax rate was lower than the statutory federal rate of 21%, primarily due to permanent difference on dividends and changes in the valuation allowance. For the three months ended June 30, 2020, the effective tax rate was lower than the statutory federal rate of 21%, primarily due to changes in the valuation allowance and partnership income for which there was no tax expense, as such income is allocated to the partners. For the six months ended June 30, 2021, we recorded an income tax expense of $76 million on pre-tax income of $613 million compared to an income tax benefit of $52 million on pre-tax loss of $1,494 million for the six months ended June 30, 2020. Our effective income tax rate was 12.4% and 3.5% for the six months ended June 30, 2021 and 2020, respectively. For the six months ended June 30, 2021, the effective tax rate was lower than the statutory federal rate of 21%, primarily due to partnership income for which there was no tax expense, as such income is allocated to the partners. For the six months ended June 30, 2020, the effective tax rate was lower than the statutory federal rate of 21%, primarily due to changes in the valuation allowance and partnership loss for which there was no tax benefit, as such loss is allocated to the partners.

Commitments and Contingencies

Commitments and Contingencies	6 Months Ended

Commitments and Contingencies Disclosure [Abstract]
Commitments and Contingencies	16. Commitments and Contingencies Environmental Matters Due to the nature of our business, certain of our subsidiaries’ operations are subject to numerous existing and proposed laws and governmental regulations designed to protect the environment, particularly regarding plant wastes and emissions and solid waste disposal. Our consolidated environmental liabilities were $38 million and $37 million as of June 30, 2021 and December 31, 2020, respectively, primarily within our Metals and Energy segments and which are included in accrued expenses and other liabilities in our condensed consolidated balance sheets. We do not believe that environmental matters will have a material adverse impact on our consolidated results of operations and financial condition. On August 21, 2018, CVR Refining received a letter from the United States Department of Justice (the “DOJ”) on behalf of the Environmental Protection Agency (the “EPA”) and the Kansas Department of Health and Environment (“KDHE”) alleging violations of the Clean Air Act and a 2012 Consent Decree (“CD”) between CVR Refining, the United States (on behalf of the EPA) and KDHE at CVR Energy’s Coffeyville refinery. In June 2020, a tolling agreement between the parties relating to such allegations expired, and the United States and KDHE sent demand letters relating to the allegations (the “Stipulated Claims”) and seeking stipulated penalties. In February 2021, the DOJ and KDHE sent CVR Refining a statement of position under the CD regarding its demand for Stipulated Claims. As CVR Refining disputes most claims asserted by the government, in accordance with the CD, CVR Refining deposited funds into a commercial escrow account pending resolution of disputed claims. The escrowed funds are legally restricted for use and are included within other assets on the consolidated balance sheets. In December 2020, the DOJ and KDHE filed a supplement complaint in the United States District Court for the District of Kansas asserting nine counts for alleged violations of the Clean Air Act, the Kansas State Implementation Plan and Kansas law (the “Statutory Claims”) and seeking civil penalties, injunctive and related relief. Our Energy segment has responded to numerous information request and negotiations relating to the Stipulated Claims and the Statutory Claims are ongoing and CVR Energy cannot at this time determine the outcome of this matter, including whether such outcome, or any subsequent enforcement or litigation relating thereto would have a material impact on our Energy segment’s financial position, results of operations, or cash flows. Renewable Fuel Standards CVR Refining is subject to the Renewable Fuel Standard (“RFS”) implemented primarily by the EPA which requires refiners to either blend renewable fuels in with their transportation fuels or purchase renewable fuel credits, known as RINs, in lieu of blending. CVR Refining is not able to blend the substantial majority of its transportation fuels and has to purchase RINs on the open market and may have to obtain waiver credits for cellulosic biofuels or other exemptions from the EPA, in order to comply with the RFS. For the three months ended June 30, 2021 and 2020, our Energy segment recognized expenses of $173 million and $16 million, respectively, for CVR Refining’s compliance with the RFS and which is included in cost of goods sold in the condensed consolidated statements of operations. For the six months ended June 30, 2021 and 2020, such expenses were $351 million and $35 million, respectively. These recognized expenses represent costs to comply with the RFS obligation through purchasing of RINs not otherwise reduced by blending of ethanol or biodiesel. At each reporting period, to the extent RINs purchased or generated through blending are less than the RFS obligation (excluding the impact of exemptions or waivers to which CVR Refining may be entitled), the remaining position is marked-to-market using RIN market prices at period end. As of June 30, 2021 and December 31, 2020, CVR Refining’s RFS position was $485 million and $214 million, respectively, and is included in accrued expenses and other liabilities in the condensed consolidated balance sheets. Litigation From time to time, we and our subsidiaries are involved in various lawsuits arising in the normal course of business. We do not believe that such normal routine litigation will have a material effect on our financial condition or results of operations. Energy On July 26, 2021, trial commenced in the consolidated lawsuits filed by purported former unitholders of CVR Refining on behalf of themselves and an alleged class of similarly situated unitholders against CVR Energy, CVR Refining and its general partner, CVR Refining Holdings, Icahn Enterprises and certain directors and affiliates in the Court of Chancery of the State of Delaware related to CVR Energy’s exercise of the call option under the CVR Refining Amended and Restated Agreement of Limited Partnership assigned to it by CVR Refining’s general partner (the “Delaware Lawsuits”) primarily alleging breach of contract, tortious interference, and breach of the implied covenant of good faith and fair dealing, which trial concluded on July 29, 2021. CVR Energy believes the Delaware Lawsuits are without merit and has vigorously defended against them. As no ruling in the case has yet been issued, CVR Energy cannot determine at this time the outcome of the Delaware Lawsuits, including whether the outcome would have a material impact on our Energy segment’s financial position, results of operations, or cash flows. The lawsuit filed in the United States District Court for the Southern District of New York also related to CVR Energy’s exercise of the call option was voluntarily dismissed. Other Matters Pension Obligations Mr. Icahn, through certain affiliates, owns 100% of Icahn Enterprises GP and approximately 90% of Icahn Enterprises’ outstanding depositary units as of June 30, 2021. Applicable pension and tax laws make each member of a “controlled group” of entities, generally defined as entities in which there is at least an 80% common ownership interest, jointly and severally liable for certain pension plan obligations of any member of the controlled group. These pension obligations include ongoing contributions to fund the plan, as well as liability for any unfunded liabilities that may exist at the time the plan is terminated. In addition, the failure to pay these pension obligations when due may result in the creation of liens in favor of the pension plan or the Pension Benefit Guaranty Corporation (the “PBGC”) against the assets of each member of the controlled group. As a result of the more than 80% ownership interest in us by Mr. Icahn’s affiliates, we and our subsidiaries are subject to the pension liabilities of entities in which Mr. Icahn has a direct or indirect ownership interest of at least 80%, which includes the liabilities of pension plans sponsored by Viskase and ACF Industries LLC (“ACF”), an affiliate of Mr. Icahn. All the minimum funding requirements of the Internal Revenue Code, as amended, and the Employee Retirement Income Security Act of 1974, as amended, for the Viskase and ACF plans have been met as of June 30, 2021. If the plans were voluntarily terminated, they would be underfunded by approximately $114 million as of June 30, 2021. These results are based on the most recent information provided by the plans’ actuaries. These liabilities could increase or decrease, depending on a number of factors, including future changes in benefits, investment returns, and the assumptions used to calculate the liability. As members of the controlled group, we would be liable for any failure of Viskase or ACF to make ongoing pension contributions or to pay the unfunded liabilities upon a termination of the Viskase or ACF pension plans. In addition, other entities now or in the future within the controlled group in which we are included may have pension plan obligations that are, or may become, underfunded and we would be liable for any failure of such entities to make ongoing pension contributions or to pay the unfunded liabilities upon termination of such plans. The current underfunded status of the pension plans of Viskase and ACF requires them to notify the PBGC of certain “reportable events,” such as if we cease to be a member of the Viskase or ACF controlled group, or if we make certain extraordinary dividends or stock redemptions. The obligation to report could cause us to seek to delay or reconsider the occurrence of such reportable events. Starfire Holding Corporation (“Starfire”), which is 99.6% owned by Mr. Icahn, has undertaken to indemnify us and our subsidiaries from losses resulting from any imposition of certain pension funding or termination liabilities that may be imposed on us and our subsidiaries or our assets as a result of being a member of the Icahn controlled group, including ACF. The Starfire indemnity provides, among other things, that so long as such contingent liabilities exist and could be imposed on us, Starfire will not make any distributions to its stockholders that would reduce its net worth to below $250 million. Nonetheless, Starfire may not be able to fund its indemnification obligations to us. Other The U.S. Attorney’s office for the Southern District of New York contacted Icahn Enterprises L.P. in September 2017 seeking production of information pertaining to our and Mr. Icahn’s activities relating to the Renewable Fuels Standard and Mr. Icahn’s former role as an advisor to the former President of the United States. We cooperated with the request and provided information in response to the subpoena. The U.S. Attorney’s office for the Southern District of New York contacted Icahn Enterprises L.P. in June 2018 seeking production of information pertaining to trading in Manitowoc Company, Inc. securities. We cooperated with the request and provided documents in response to the subpoena. The U.S. Attorney’s office has not made any claims or allegations against us or Mr. Icahn with respect to either of the foregoing inquiries. We believe that we maintain a strong compliance program and, while no assurances can be made, we do not believe these inquiries will have a material impact on our business, financial condition, results of operations or cash flows.

Subsequent Events Icahn Enterprises LP Unit Distribution On August 4, 2021, the Board of Directors of the general partner of Icahn Enterprises declared a quarterly distribution in the amount of $2.00 per depositary unit, which will be paid on or about September 29, 2021 to depositary unitholders of record at the close of business on August 20, 2021. Depositary unitholders will have until September 17, 2021 to make a timely election to receive either cash or additional depositary units. If a unitholder does not make a timely election, it will automatically be deemed to have elected to receive the distribution in additional depositary units. Depositary unitholders who elect to receive (or who are deemed to have elected to receive) additional depositary units will receive units valued at the volume weighted average trading price of the units during the 5 consecutive trading days ending September 24, 2021. Icahn Enterprises will make a cash payment in lieu of issuing fractional depositary units to any unitholders electing to receive (or who are deemed to have elected to receive) depositary units.

Accounting Policies [Abstract]
Principles of Consolidation	Principles of Consolidation Our condensed consolidated financial statements include the accounts of (i) Icahn Enterprises and Icahn Enterprises Holdings and (ii) the wholly and majority owned subsidiaries of Icahn Enterprises and Icahn Enterprises Holdings, in addition to variable interest entities (“VIEs”) in which we are the primary beneficiary. In evaluating whether we have a controlling financial interest in entities that we consolidate, we consider the following: (1) for voting interest entities, including limited partnerships and similar entities that are not VIEs, we consolidate these entities in which we own a majority of the voting interests; and (2) for VIEs, we consolidate these entities in which we are the primary beneficiary. See below for a discussion of our VIEs. Kick-out rights, which are the rights underlying the limited partners’ ability to dissolve the limited partnership or otherwise remove the general partners, held through voting interests of partnerships and similar entities that are not VIEs are considered the equivalent of the equity interests of corporations that are not VIEs. Except for our Investment segment and Holding Company, for equity investments in which we own 50% or less but greater than 20%, we generally account for such investments using the equity method. All other equity investments are accounted for at fair value.
Reclassifications	Reclassifications Certain reclassifications from the prior year presentation have been made to conform to the current year presentation, which did not have an impact on previously reported net income and equity and are not deemed material.
Consolidated Variable Interest Entities	Consolidated Variable Interest Entities The following is a discussion of variable interest entities in which we are deemed to be the primary beneficiary and we therefore consolidate. Icahn Enterprises Holdings We determined that Icahn Enterprises Holdings is a VIE because it is a limited partnership that lacks both substantive kick-out and participating rights. Although Icahn Enterprises is not the general partner of Icahn Enterprises Holdings, Icahn Enterprises is deemed to be the primary beneficiary of Icahn Enterprises Holdings principally based on its 99% limited partner interest in Icahn Enterprises Holdings, as well as our related party relationship with the general partner, and therefore continues to consolidate Icahn Enterprises Holdings. The condensed consolidated financial statements of Icahn Enterprises Holdings are included in this Report. The balances with respect to Icahn Enterprises Holdings’ consolidated VIEs are discussed below, comprising the Investment Funds, CVR Partners and Viskase’s joint venture. Investment We determined that each of the Investment Funds are considered VIEs because these limited partnerships lack both substantive kick-out and participating rights. Because we have a general partner interest in each of the Investment Funds and have significant limited partner interests in each of the Investment Funds, coupled with our significant exposure to losses and benefits in each of the Investment Funds, we are the primary beneficiary of each of the Investment Funds and therefore continue to consolidate each of the Investment Funds. Energy CVR Partners is considered a VIE because it is a limited partnership that lacks both substantive kick-out and participating rights. In addition, CVR Energy also concluded that, based upon its general partner’s roles and rights in CVR Partners as afforded by CVR Partners’ partnership agreement, coupled with its exposure to losses and benefits in CVR Partners through its significant limited partner interest, intercompany credit facilities and services agreements, it is the primary beneficiary of CVR Partners. Food Packaging Viskase holds a variable interest in a joint venture for which Viskase is the primary beneficiary. Viskase’s interest in the joint venture includes a 50% equity interest and also relates to the sales, operations, administrative and financial support to the joint venture through providing many of the assets used in its business. ​ The following table includes balances of assets and liabilities of VIE’s included in Icahn Enterprises Holdings’ condensed consolidated balance sheets. ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ June 30, ​ December 31, ​ 2021 2020 ​ ​ (in millions) Cash and cash equivalents ​ $ 49 ​ $ 31 Cash held at consolidated affiliated partnerships and restricted cash ​ 1,218 ​ 1,558 Investments ​ 10,603 ​ 8,239 Due from brokers ​ 4,358 ​ 3,437 Accounts receivable, net ​ ​ 35 ​ ​ 37 Inventories, net ​ 50 ​ 42 Property, plant and equipment, net ​ 1,007 ​ 1,042 Unrealized gain on derivative contracts ​ ​ 679 ​ ​ 785 Intangible assets, net ​ 222 ​ 232 Other assets ​ 59 ​ 107 Accounts payable ​ 30 ​ 25 Accrued expenses and other liabilities ​ ​ 82 ​ ​ 70 Deferred tax liabilities ​ ​ 1 ​ ​ 1 Unrealized loss on derivative contracts ​ ​ 728 ​ ​ 622 Securities sold, not yet purchased, at fair value ​ 4,231 ​ 2,521 Due to brokers ​ 1,528 ​ 1,618 Debt ​ 640 ​ 636
Fair Value of Financial Instruments	Fair Value of Financial Instruments The carrying values of cash and cash equivalents, cash held at consolidated affiliated partnerships and restricted cash, accounts receivable, due from brokers, accounts payable, accrued expenses and other liabilities and due to brokers are deemed to be reasonable estimates of their fair values because of their short-term nature. See Note 4, “Investments,” and Note 5, “Fair Value Measurements,” for a detailed discussion of our investments and other non-financial assets and/or liabilities. The fair value of our long-term debt is based on the quoted market prices for the same or similar issues or on the current rates offered to us for debt of the same remaining maturities. The carrying value and estimated fair value of our long-term debt as of June 30, 2021 was approximately $8.1 billion and $8.2 billion, respectively. The carrying value and estimated fair value of our long-term debt as of December 31, 2020 was approximately $8.1 billion and $8.2 billion, respectively.
Cash Flow	Cash Flow Cash and cash equivalents and restricted cash and restricted cash equivalents on our condensed consolidated statements of cash flows is comprised of (i) cash and cash equivalents and (ii) cash held at consolidated affiliated partnerships and restricted cash.
Cash Held at Consolidated Affiliated Partnerships and Restricted Cash	Cash Held at Consolidated Affiliated Partnerships and Restricted Cash Our cash held at consolidated affiliated partnerships balance was $223 million and $686 million as of June 30, 2021 and December 31, 2020, respectively. Cash held at consolidated affiliated partnerships relates to our Investment segment and consists of cash and cash equivalents held by the Investment Funds that, although not legally restricted, are not available to fund the general liquidity needs of the Investment segment or Icahn Enterprises. Our restricted cash balance was $1,046 million and $926 million as of June 30, 2021 and December 31, 2020, respectively. Restricted cash primarily relates to our Investment segment’s cash pledged and held for margin requirements on derivative transactions.
Revenue From Contracts With Customers and Contract Balances	Revenue From Contracts With Customers and Contract Balances Due to the nature of our business, we derive revenue from various sources in various industries. With the exception of all of our Investment segment’s and our Holding Company’s revenues, and our Real Estate segment’s leasing revenue, our revenue is generally derived from contracts with customers in accordance with U.S. GAAP. Such revenue from contracts with customers is included in net sales and other revenues from operations in the condensed consolidated statements of operations, however, our Real Estate segment’s leasing revenue, as disclosed in Note 9, “Leases,” is also included in other revenues from operations. Related contract assets are included in accounts receivable, net or other assets and related contract liabilities are included in accrued expenses and other liabilities in the condensed consolidated balance sheets. Our disaggregation of revenue information includes our net sales and other revenues from operations for each of our reporting segments as well as additional disaggregation of revenue information for our Energy and Automotive segments. See Note 12, “Segment Reporting,” for our complete disaggregation of revenue information. In addition, we disclose additional information with respect to revenue from contracts with customers and contract balances for our Energy and Automotive segments below. Energy Our Energy segment’s deferred revenue is a contract liability that primarily relates to fertilizer sales contracts requiring customer prepayment prior to product delivery to guarantee a price and supply of nitrogen fertilizer. Deferred revenue is recorded at the point in time in which a prepaid contract is legally enforceable and the associated right to consideration is unconditional prior to transferring product to the customer. An associated receivable is recorded for uncollected prepaid contract amounts. Contracts requiring prepayment are generally short-term in nature and revenue is recognized at the point in time in which the customer obtains control of the product. Our Energy segment had deferred revenue of $16 million and $31 million as of June 30, 2021 and December 31, 2020, respectively. For the six months ended June 30, 2021 and 2020, our Energy segment recorded revenue of $30 million and $27 million, respectively, with respect to deferred revenue outstanding as of the beginning of each respective period, which includes $22 million and $21 million recognized during the three months ended June 30, 2021 and 2020, respectively. As of June 30, 2021, our Energy segment had $6 million of remaining performance obligations for contracts with an original expected duration of more than one year. Our Energy segment expects to recognize approximately $3 million of these performance obligations as revenue by the end of 2021 and the remaining balance thereafter. Automotive Our Automotive segment has deferred revenue with respect to extended warranty plans of $41 million at each of June 30, 2021 and December 31, 2020, which are included in accrued expenses and other liabilities on the condensed consolidated balance sheets. For the six months ended June 30, 2021 and 2020, our Automotive segment recorded revenue of $12 million and $13 million, respectively, with respect to deferred revenue outstanding as of the beginning of each respective period, which includes $6 million and $7 million recognized during the three months ended June 30, 2021 and 2020, respectively.
Adoption of New Accounting Standards	Adoption of New Accounting Standards In December 2019, the Financial Account Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) 2019-12, Simplifying the Accounting for Income Taxes Income Taxes standard and modifies other areas of the standard to clarify the application of U.S. GAAP. This ASU is effective for fiscal years beginning after December 15, 2020, and interim periods within those fiscal years. We have adopted this standard on January 1, 2021. Certain amendments in this ASU are applied using a retrospective approach and others using the prospective approach. The adoption of this standard did not have a significant impact on our condensed consolidated financial statements.

Fair Value Disclosures [Abstract]
Determination of when transfers between fair value levels occurs	In certain cases, the inputs used to measure fair value may fall into different levels of the fair value hierarchy. In such cases, the level within the fair value hierarchy is based on the lowest level of input that is significant to the fair value measurement. Our assessment of the significance of a particular input to the fair value measurement in its entirety requires judgment and consideration of factors specific to the assets and liabilities. Significant transfers, if any, between the levels within the fair value hierarchy are recognized at the beginning of the reporting period when changes in circumstances require such transfers.

Segment Reporting [Abstract]
Determination of what constitutes a segment	We report segment information based on the various industries in which our businesses operate and how we manage those businesses in accordance with our investment strategies, which may include: identifying and acquiring undervalued assets and businesses, often through the purchase of distressed securities; increasing value through management, financial or other operational changes; and managing complex legal, regulatory or financial issues, which may include bankruptcy or insolvency, environmental, zoning, permitting and licensing issues. Therefore, although many of our businesses are operated under separate local management, certain of our businesses are grouped together when they operate within a similar industry, comprising similarities in products, customers, production processes and regulatory environments, and when such businesses, when considered together, may be managed in accordance with one or more investment strategies specific to those businesses. Among other measures, we assess and measure segment operating results based on net income from continuing operations attributable to Icahn Enterprises and Icahn Enterprises Holdings. Certain terms of financings for certain of our businesses impose restrictions on the business’ ability to transfer funds to us, including restrictions on dividends, distributions, loans and other transactions.
