Bitcoin’s biggest ETF is becoming the sell wall bulls have to break
BlackRock’s IBIT, the largest U.S. spot Bitcoin ETF, became the main source of pressure during a weak week for Bitcoin. US spot Bitcoin ETFs lost about $1.79 billion in June 22–26 flows, and IBIT accounted for roughly $1.30 billion, including the full $444.5 million ETF outflow on June 26. That matters because IBIT is both a major demand channel and now a potential redemption channel. The flows suggest ETF ownership is becoming more price-sensitive near Bitcoin’s $60,000 area. A weekly outflow of this size does not prove direct spot selling, but it does signal real transmission risk: if ETF holders keep de-risking, the broader market must absorb the exposure. IBIT’s scale makes the move important even though the outflow is small relative to its $44.9 billion in assets. The next test is whether outflows slow and Bitcoin reclaims $59,000–$62,000, or whether continued redemptions deepen the sell-wall narrative.
