Equity Method Investments and Joint Ventures [Abstract]
Investments	Investments Equity Investments Dun & Bradstreet In connection with our acquisition of Black Knight, we acquired an investment in Dun & Bradstreet Holdings, Inc., or D&B, a global provider of business decisioning data and analytics, which we classified as an equity investment. Subsequent to the Black Knight acquisition and prior to December 31, 2023, we sold the entire investment for a total of $187 million and realized a total loss of $3 million on the sale, net of dividends received, which is included in other income/(expense), net in our consolidated statement of income in 2023. Euroclear We previously owned a 9.8% stake in Euroclear, plc, or Euroclear, that we originally purchased for $631 million. We participated on the Euroclear Board of Directors, and we classified our investment in Euroclear as an equity investment. On May 20, 2022, we completed the sale of our 9.8% stake in Euroclear. The carrying value of our investment was $700 million at the time of the sale. We recorded a net gain on the sale of $41 million, which is included in other income/(expense), net in our consolidated statement of income in 2022. Equity Method Investments Our equity method investments include OCC and Bakkt Holdings, Inc., and Bakkt Opco Holdings, LLC, or collectively, Bakkt, among others. We recognized $62 million, $122 million and $1.3 billion as our share of estimated losses, net, from our equity method investments included in other income/(expense), net in our consolidated statements of income during 2024, 2023 and 2022, respectively. The estimated losses during 2024, 2023 and 2022 are primarily related to our investment in Bakkt, partially offset by our share of OCC profits. In addition, during 2022, after recording our share of Bakkt's equity method losses, which included an impairment charge recorded by Bakkt, we recorded an impairment in our investment in Bakkt to its fair value as other expense. Each period includes adjustments to reflect the difference between reported prior period actual results from our original estimates. When performing our assessment of the carrying value of our investments, we consider, among other things, the length of time and the extent to which the market value has been less than our cost basis, if applicable, the investee's financial condition and near-term prospects, the economic or technological environment in which our investees operate, weakening of the general market condition of the related industry, whether an investee can continue as a going concern, any impairment charges recorded by an investee on goodwill, intangible or long-lived assets, and our intent and ability to retain the investment for a period of time sufficient to allow for any anticipated recovery in market value. OCC We own a 40% interest in OCC through a direct investment by the NYSE. OCC is regulated by the SEC as a registered clearing agency and by the Commodity Futures Trading Commission, or CFTC, as a derivatives clearing organization. OCC serves as a clearing house for securities options, security futures, commodity futures and options on futures traded on various independent exchanges. OCC clears securities options traded on NYSE Arca and NYSE Amex Options, along with other non-affiliated exchanges. Bakkt As of December 31, 2024, and December 31, 2023, we held an approximate 54% and 64% economic interest in Bakkt, respectively. As a result of limitations on ICE from the Bakkt voting agreement entered into in connection with Bakkt's merger with Victory Park Capital Impact Acquisition Holdings, or VIH, we hold a minority voting interest in Bakkt and treat it as an equity method investment. The decrease in ownership during 2024 was related to Bakkt's offering of shares of its Class A common stock and warrants to purchase shares of its Class A common stock, which diluted our ownership. As part of the offering, on February 29, 2024, we entered into a securities purchase agreement to purchase shares of Bakkt's Class A common stock and warrants to purchase additional shares of Bakkt's Class A common stock for a total of $10 million. As of December 31, 2024, we do not have any value assigned to the equity method investment carrying value for Bakkt primarily due to our continued recording of our share of losses. As Bakkt is a public company with a readily available market price, the fair value of our investment was $185 million as of December 31, 2024, which was based on the quoted market price of Bakkt Class A common stock as of December 31, 2024. On August 12, 2024, we entered into a revolving credit agreement with Bakkt pursuant to which we have agreed to provide Bakkt with a $40 million secured revolving line of credit that matures on December 31, 2026. The $40 million is available in defined commitment amounts for specified time periods in the future. No amounts were permitted to be borrowed without our consent prior to December 31, 2024, after which date the amount Bakkt may borrow will increase over time up to a maximum of $40 million on or after September 30, 2025. As an equity method investee, Bakkt is a related party of ICE. There were no amounts outstanding under the revolving credit agreement as of December 31, 2024. We recorded estimated equity losses and impairment of $1.4 billion during 2022 related to our investment in Bakkt, which included the impairment discussed above, and was based on what we consider to be an other-than-temporary decline in fair value as a result of the factors noted above, and included consideration for the impairment charge recorded by Bakkt. We concluded that Bakkt met the significance test under Rule 3-09 of Regulation S-X for 2022. Bakkt's total assets and liabilities as of December 31, 2022 were $455 million and $119 million, respectively, and Bakkt's net revenues and net loss in 2022 were $55 million and $2.0 billion, respectively. Bakkt no longer met the significance test in 2024 or 2023. However, in accordance with Rule 3-09 of Regulation S-X, since Bakkt met the significance test for a prior year presented in these financial statements, Bakkt financial statements as of and for the year ended December 31, 2024 will be filed by us subsequent to the filing of our Form 10-K as an amendment to this Form 10-K.
