Whale Dumps $1.29B of BlackRock IBIT in Dark Pool Trade!

A massive $1.29 billion dark pool block trade tied to BlackRock's IBIT Bitcoin ETF crossed Nasdaq on Tuesday, involving nearly 29 million shares in a single transaction. The size briefly exceeded IBIT's typical daily trading volume — a rare event that signals a large institutional holder, or whale, quietly unwinding a significant position away from the open market.

Dark pool trades are designed to minimize price impact, but a block this size is difficult to hide entirely. The fact that it surfaced on Nasdaq's reporting tape means the trade is now visible to the broader market, and the directional read is straightforward: a major IBIT holder chose to exit, or at minimum redistribute, a position worth over a billion dollars without broadcasting intent through the lit order book.
