BlackRock’s grip on the Bitcoin ETF market just tightened further.
Its iShares Bitcoin Trust (IBIT) has now accumulated over 700,000 BTC, pushing its total holdings beyond $75 billion. The latest inflows—over $160 million on Monday—underscore the relentless pace of institutional accumulation this year.
The asset manager now commands more than half of all BTC held across U.S. spot ETFs, with IBIT alone accounting for over 55% of the total, according to Bitbo. Since launching in January, the fund has already returned more than 80%—outperforming even BlackRock’s S&P 500 ETF, which it recently overtook in revenue generation.
The buying spree isn’t limited to BlackRock. Combined with Strategy Inc., the largest corporate BTC holder, U.S. ETFs have snapped up nearly $28.2 billion worth of Bitcoin in 2025. That dwarfs miner output for the same period, which totaled just $7.85 billion—showing consistent monthly demand outpacing supply, apart from a brief February selloff.
Meanwhile, regulators appear to be smoothing the path for future ETF products. The SEC is reportedly preparing a streamlined approval process, requiring only a 75-day review following an S-1 filing. This follows the recent debut of the first staked crypto ETF in the U.S., offering exposure to Solana (SOL) and staking yields—signaling further momentum in mainstream crypto adoption.
