BlackRock's Bitcoin ETF Now Holds More BTC Than Any Corporation, Closing In On 800,000 Coins

BlackRock's iShares Bitcoin Trust (IBIT) now holds more Bitcoin than any corporate treasury in the world, with total holdings just below 800,000 BTC—valued at approximately $56 billion. Over the past week alone, IBIT added roughly $600 million in Bitcoin, according to on-chain data tracked by Arkham Intelligence. That accumulation has pushed it ahead of Strategy Inc (MSTR), which holds 780,897 BTC, or about $55 billion, after adding 13,927 BTC on Monday at an average price of $71,902 per coin. The 8,030-BTC gap means Strategy would need to spend another $600 million to reclaim the top spot. Strategy Executive Chairman Michael Saylor signaled ongoing commitment to expansion with a Sunday post reading “Think ₿igger” and a chart of recent purchases. Meanwhile, BlackRock is building beyond passive exposure: it recently filed an amended S-1 with the SEC for the iShares Bitcoin Premium Income ETF, expected to trade under BITA, which will generate income via a covered call strategy on its Bitcoin holdings—marking a shift from pure spot-price tracking. IBIT’s growth has cemented its position as the largest Bitcoin investment vehicle in the market, even as its stock dipped more than 3% in pre-market trading Friday, with retail sentiment on Stocktwits remaining bearish. The new filing underscores BlackRock’s deepening institutional bet on Bitcoin as both an asset and a platform for structured financial products. BlackRock's iShares Bitcoin Trust (IBIT) bought approximately $600 million in Bitcoin over the past week.
