Did BlackRock just dump $5 billion of Bitcoin this week?

BlackRock’s Bitcoin stash has shrunk by more than $5 billion in just one week, with blockchain data showing steady outflows from the world’s largest asset manager’s ETF addresses. As of August 20, 2025, BlackRock held 749,940 BTC worth $87.22 billion. By August 27, those holdings had dropped to 744,590 BTC valued at $81.74 billion. The decline reveals both a 5,360 BTC reduction in balances and a 6.28% drop in price, with Bitcoin sliding $6,522 over the same period. BlackRock Bitcoin holdings.

More than a dozen such transactions were recorded in the past 12 hours alone, raising speculation about ETF redemptions or internal fund rebalancing. Bitcoin falls 5% in a week The moves coincide with broader market weakness. Bitcoin has fallen 5.61% in the past week, underperforming Ethereum and most large-cap altcoins, as traders digest profit-taking flows and uncertainty around the Federal Reserve’s next policy shift. Despite the drawdown, BlackRock remains by far the largest institutional holder of Bitcoin, with over $81.7 billion in BTC on its books, dwarfing holdings from competitors like Fidelity and Ark Invest. But the scale and regularity of the recent transfers has drawn market attention, with analysts warning that persistent ETF outflows could pressure prices further if sustained. For now, BlackRock’s IBIT ETF continues to lead in assets under management, but on-chain data suggests that the institutional rotation out of Bitcoin, and into Ethereum may be gathering pace. The coming weeks will be crucial in determining whether BlackRock’s latest Bitcoin shuffle is a short-term liquidity adjustment or the start of a deeper reallocation.
