BlackRock’s Bitcoin ETF Records 10 Straight Days of Outflows as Institutional Selling Persists

Key Highlights

• BlackRock’s iShares Bitcoin Trust (IBIT) has now logged 10 consecutive trading days of net outflows
• The fund has seen roughly $2.3 billion leave the ETF since mid-May
• Total US spot Bitcoin ETF outflows have exceeded $3.7 billion over the same period
• The largest single-day IBIT withdrawal reached approximately $527.8 million
• Institutional investors appear to be reducing Bitcoin exposure amid market uncertainty
• ETF flows continue to play a major role in short-term Bitcoin price action
• Recent data suggests selling pressure may be slowing, though the trend remains negative

BlackRock’s iShares Bitcoin Trust has entered its longest sustained outflow streak since launch, recording ten consecutive trading days of investor withdrawals as institutional demand for Bitcoin continues to weaken. According to recent ETF flow data, the fund has shed more than $2.3 billion since the streak began in mid-May, making it one of the most significant periods of selling pressure since US spot Bitcoin ETFs first entered the market.

The outflows have not been limited to BlackRock alone. Across all US-listed spot Bitcoin ETFs, investors have withdrawn roughly $3.7 billion over the past two weeks, reflecting a broader reduction in institutional exposure to the asset class. The trend marks a sharp reversal from earlier periods in 2026 when ETFs were consistently attracting fresh capital and helping support Bitcoin’s upward momentum.

One of the most notable sessions occurred on May 27, when IBIT recorded approximately $527.8 million in net outflows, its second-largest single-day withdrawal on record. That same day, the broader ETF market experienced more than $733 million in total outflows, highlighting how widespread the selling pressure had become across major fund providers.

Analysts say the withdrawals likely reflect a combination of factors, including macroeconomic uncertainty, profit-taking, and shifting institutional portfolio allocations. Bitcoin has also underperformed some of the strongest-performing sectors of the year, particularly artificial intelligence and semiconductor-related equities, which continue attracting significant investor capital.

ETF flows have become increasingly important to Bitcoin’s market structure since the approval of spot products in the United States. Large inflows often create sustained buying pressure because ETF issuers must acquire Bitcoin to back new shares. The reverse is also true: persistent redemptions can generate additional selling pressure as underlying Bitcoin holdings are reduced to meet investor withdrawals.

Despite the negative trend, some market observers point out that the pace of outflows has recently started to moderate. The latest daily figures were noticeably smaller than some of the larger withdrawal sessions seen earlier in the streak, raising the possibility that selling momentum could be beginning to slow.

Others remain cautious, noting that sustained ETF outflows have historically coincided with periods of weaker Bitcoin price performance and reduced institutional risk appetite. The current streak has also emerged during a period of broader market uncertainty, including geopolitical tensions and changing expectations around interest rates and global liquidity.

Even with the recent withdrawals, BlackRock’s Bitcoin ETF remains one of the largest institutional Bitcoin investment vehicles in the world and continues to hold substantial assets under management. Long-term adoption of regulated Bitcoin products remains significantly higher than it was before the ETF era, despite the current period of weakness.

For now, investors are closely watching whether the outflow streak finally breaks in the coming sessions or whether institutional selling continues to weigh on Bitcoin as market participants reassess risk exposure across digital assets.
