Subsequent Events [Abstract]
Subsequent Events	24. Subsequent Events In June 2024, BlackRock announced that it had entered into a definitive agreement to acquire Preqin, a leading independent provider of private markets data, for £2.55 billion (or approximately $3.4 billion based on the GBP/USD foreign exchange rate at September 30, 2024) in cash. 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 anticipated to close in the first quarter of 2025, subject to regulatory approvals and other customary closing conditions. In October 2024, BlackRock completed the acquisition of 100% of the issued and outstanding limited liability company interests of GIP for a total consideration of approximately $3 billion in cash and approximately 12 million shares of BlackRock common stock. At close, 6.9 million shares were issued, and the remaining deferred consideration, all in stock, 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 creates a broad global infrastructure franchise with differentiated origination and asset management capabilities. The initial accounting for the business combination is incomplete as a result of the timing of the acquisition. Therefore, it is impractical for the Company to provide the full disclosure of required financial information at the filing date. As a result of the closing of the GIP Transaction, on October 1, 2024, (1) BlackRock, Inc. (formerly known as BlackRock Funding, Inc.)
