BlackRock saw a massive $1.29 billion dark pool transaction tied to its IBIT Bitcoin ETF, involving nearly 29 million shares traded on Nasdaq. According to Alex Thorn, it was the largest IBIT block trade he had seen. The trade briefly surpassed the ETF’s normal daily trading volume, highlighting strong institutional activity in spot Bitcoin products. Despite the scale of the transaction, Bitcoin held above $75,000, suggesting the market absorbed the order without major volatility. Traders are now watching whether large institutional positioning continues supporting ETF inflows and Bitcoin price stability.
