Bitcoin came under renewed pressure as a massive block trade hit BlackRock’s iShares Bitcoin Trust and U.S. spot Bitcoin ETF outflows continued to build.
Roughly 29 million IBIT shares worth about $1.29 billion changed hands in a dark pool block trade on May 26, marking one of the largest trades seen in a spot Bitcoin ETF. The trade coincided with a weaker stretch for Bitcoin, which had fallen from above $82,000 in early May to below $77,000.
ETF Outflows Hit $333.6M on May 26
The IBIT trade landed during an already fragile period for ETF demand. U.S.-listed spot Bitcoin ETFs lost more than $2.26 billion over the previous two weeks, with another $333.6 million in net outflows recorded on May 26.
IBIT accounted for about $192.4 million of those outflows. Fidelity’s FBTC lost $57.7 million, while Bitwise’s BITB saw $28.8 million leave the fund. That made the pressure broader than one BlackRock-linked trade.
$1.29B IBIT Print Does Not Prove Bitcoin Dump
A large IBIT block trade is not the same thing as a direct Bitcoin sale on a public exchange. The transaction shows that one or more large counterparties traded a major IBIT position while sentiment was already weak. It does not prove that Bitcoin was immediately sold into the open market.
That distinction matters because ETF activity can move in several ways. Large investors can rebalance, transfer exposure, close positions or shift risk through block trades without creating the same visible order-book pressure as an exchange sale. Still, the size of the trade drew attention because ETF flows have been one of Bitcoin’s main demand pillars since the products launched.
IBIT Weakness Spreads Across Spot Bitcoin ETFs
The latest weakness is not limited to BlackRock. Outflows across IBIT, FBTC, BITB and other funds suggest investors are reducing exposure across the spot Bitcoin ETF market.
That makes the move look more like a sector-wide pullback than a single-fund event. For Bitcoin, the near-term issue is whether ETF demand stabilizes after two weeks of steady redemptions.
Bitcoin Waits for ETF Demand to Steady
The market is now trying to absorb both the $1.29 billion IBIT block trade and continued ETF outflows. Bitcoin was already trading under $77,000 as the redemptions continued.
Unless ETF demand steadies, large trades like this are likely to keep traders focused on downside risk rather than a quick rebound. The block trade does not confirm a Bitcoin dump, but it adds to a weak ETF backdrop at a sensitive point for the market.
