Subsequent Events [Abstract]
Subsequent Events	24. Subsequent Events In January 2024, BlackRock announced that it had entered into a definitive agreement to acquire 100% of the business and assets of GIP, a leading independent infrastructure fund manager, for $3 billion in cash and approximately 12 million shares of BlackRock common stock. Approximately 30% of the total consideration, all in stock, will be deferred and will be issued subject to the satisfaction of certain post-closing events. The Company believes the combination of GIP with BlackRock’s complementary infrastructure offerings will create a broad global infrastructure franchise with differentiated origination and asset management capabilities. The GIP Transaction is expected to close around the end of the third quarter of 2024 subject to regulatory approvals and other customary closing conditions. In June 2024, BlackRock announced that it had entered into a definitive agreement to acquire 100% of the business and assets of Preqin, a leading independent provider of private markets data, for £2.55 billion (or approximately $3.2 billion based on the GBP/USD foreign exchange rate at June 30, 2024) in cash (the "Preqin Transaction"). The Company believes bringing together Preqin's data and research tools with the complementary workflows of Aladdin and eFront in a unified platform will create a preeminent private markets technology and data provider. The Preqin Transaction is expected to close before year-end 2024, subject to regulatory approvals and other customary closing conditions. In July 2024, BlackRock Funding issued $2.5 billion in aggregate principal amount of senior unsecured and unsubordinated notes. These notes were issued as three separate series of senior debt securities including $800 million of 4.60% notes maturing on July 26, 2027 (the "2027 Notes"), $500 million of 4.90% notes maturing on January 8, 2035 (the "2035 Notes") and $1.2 billion of 5.35% notes maturing on January 8, 2055 (the "2055 Notes") (collectively, the "July 2024 Notes"). Net proceeds are intended to be used to fund a portion of the cash consideration for the Preqin Transaction. Interest on the 2027 Notes of approximately $37 million per year is payable semi-annually on January 26 and July 26 of each year, beginning January 26, 2025. Interest on the 2035 Notes and 2055 Notes of approximately $25 million and $64 million per year, respectively, is payable semi-annually on January 8 and July 8 of each year, beginning January 8, 2025. The July 2024 Notes are fully and unconditionally guaranteed (the “July 2024 Notes Guarantee”) on a senior unsecured basis by BlackRock. The July 2024 Notes and the July 2024 Notes Guarantee rank equally in right of payment with all of BlackRock Funding and BlackRock’s other unsubordinated indebtedness, respectively. The July 2024 Notes may be redeemed prior to maturity at any time in whole or in part at the option of BlackRock Funding at the redemption prices set forth in the applicable series of July 2024 Notes. In addition, if the Preqin Transaction is not consummated, BlackRock Funding will be required to redeem all outstanding 2027 Notes (the “Special Mandatory Redemption”) at a Special Mandatory Redemption price equal to 101% of the aggregate principal amount of the 2027 Notes, plus accrued and unpaid interest, if any, to, but excluding, the Special Mandatory Redemption date. The Company conducted a review for additional subsequent events and determined that no subsequent events had occurred that would require accrual or additional disclosures.
