BlackRock’s BTC Hoard Hits New High
BlackRock’s iShares Bitcoin Trust (IBIT) now holds a staggering 696,874 BTC, worth approximately $74 billion as of July 1, 2025. This represents about 3.3% of Bitcoin’s total 21 million supply, making IBIT the largest institutional holder among U.S. spot Bitcoin ETFs.
This massive BTC reserve underscores BlackRock’s aggressive strategy and strong conviction in Bitcoin’s role as a long-term store of value. It also reflects growing institutional appetite for regulated, exchange-traded exposure to crypto assets.
What’s Driving the Boom?

BlackRock’s IBIT continues to dominate the spot Bitcoin ETF space. It controls more than half of the U.S. market share and recorded over $3.7 billion in new inflows in June alone. Institutions are choosing IBIT for its transparency, regulation, and easy exposure to Bitcoin.
Liquidity & Real-Time Tracking
IBIT benefits from deep market liquidity and real-time tracking of Bitcoin prices. With its assets securely custodied by Coinbase Prime, IBIT offers peace of mind for large investors and portfolio managers seeking crypto exposure without managing private keys or wallets.
