BlackRock’s flagship Bitcoin exchange-traded fund has experienced one of its most substantial withdrawal events since inception, coinciding with widespread redemptions across spot Bitcoin ETFs during a pronounced decline in cryptocurrency valuations.

According to SoSoValue data, the iShares Bitcoin Trust (IBIT) managed by BlackRock registered $527.84 million in net redemptions on Wednesday. This withdrawal volume represents the fund’s second-highest outflow day since commencing operations in January 2024.

IBIT Approaches Historical Withdrawal Record

Wednesday’s redemption activity came remarkably close to IBIT’s all-time peak withdrawal of $528.3 million, which occurred on January 30. The recent outflow fell short of that benchmark by approximately $500,000, based on figures from SoSoValue.

IBIT maintains its position as the dominant institutional Bitcoin investment vehicle, managing roughly $59 billion in total assets. The fund’s holdings constitute nearly 4% of Bitcoin’s entire circulating supply, the data reveals.

The withdrawal trend extended beyond BlackRock’s offering. SoSoValue tracking showed that all 11 U.S.-listed spot Bitcoin exchange-traded funds collectively hemorrhaged $733.43 million on Wednesday. Fidelity’s FBTC registered $60.30 million in net redemptions, while Grayscale’s GBTC saw $104.76 million exit the fund.

Bitcoin ETFs Continue Multi-Day Redemption Pattern

Fund-flow tracking indicates that U.S. spot Bitcoin ETFs have experienced consecutive sessions of investor withdrawals. Over the preceding two-week period, these products have witnessed more than $2 billion in cumulative outflows.

The ETF redemptions coincided with Bitcoin sliding below the $73,000 level. During Asian trading hours on Thursday, the cryptocurrency changed hands at $72,978, representing a 3.4% decline over the previous 24 hours, according to market data referenced in the analysis.

The price deterioration followed heightened geopolitical uncertainty after U.S. military operations targeted an Iranian military facility near the Strait of Hormuz. This development reignited conflict concerns that markets had begun to discount in recent sessions.

Billion-Dollar IBIT Transaction Draws Market Attention

A substantial off-exchange transaction involving BlackRock’s Bitcoin ETF captured market interest earlier in the week. On Tuesday, a single investor liquidated $1.29 billion worth of IBIT shares through a dark-pool block execution, according to trading data.

Dark-pool venues enable large institutional participants to execute sizable transactions privately, avoiding immediate market impact by keeping orders away from public exchanges.

The analysis clarified that block sales differ from net ETF outflows, as counterparty buyers absorb the shares being sold. IBIT’s official net redemption for Tuesday measured $192.44 million, according to the same fund-flow data.

Nevertheless, the combination of Tuesday’s block transaction and Wednesday’s substantial outflow suggests certain institutional participants have been reducing Bitcoin allocations amid deteriorating macroeconomic conditions.

Cryptocurrency Valuation Declines Amid Weakening ETF Interest

The analysis indicates that ETF accumulation patterns have decelerated markedly this year, with net additions totaling approximately 4,500 BTC. Throughout May, fund activity shifted from the consistent buying observed during March and April toward net distribution.

Bitcoin has declined from above $82,000 on May 6 to its current level below $73,000, according to market pricing data. The ETF distribution channel, which previously underpinned Bitcoin’s 2025 appreciation, has reversed course during May.

Future fund-flow patterns and Middle East geopolitical developments will determine whether current withdrawal trends prove temporary, the analysis suggests. IBIT has previously experienced brief outflow periods during the current cycle before attracting renewed inflows when macroeconomic pressures subsided.
