- • Bitcoin declined 3.6% on May 27, falling below the $73,000 level, driven by profit-taking, rising US Treasury yields, macroeconomic uncertainty from geopolitical tensions, and significant derivatives liquidations.
- • Grayscale's GBTC also posted substantial outflows of $104.8 million, while Morgan Stanley's MSBT was the only major Bitcoin ETF to record net inflows at $4.3 million, indicating selective investor positioning.

Summary
BlackRock's iShares Bitcoin Trust (IBIT) experienced a watershed moment on May 27, 2026, recording $527.8 million in net outflows during a single trading session—the largest daily redemption since the fund's launch in early 2024. This outflow occurred as part of a broader exodus from Bitcoin ETFs, with the entire US spot Bitcoin ETF complex recording $733.4 million in aggregate outflows the same day, the largest daily decline in four months and the most significant since late January 2026.
The asset flight coincided with a sharp 3.6% decline in Bitcoin's price, which fell below the $73,000 threshold. Multiple market forces converged to trigger the selloff and subsequent redemptions. Nick Ruck, director at LVRG Research, attributed the decline to profit-taking following recent highs, combined with rising US Treasury yields and macroeconomic uncertainty stemming from geopolitical tensions. Dominick John, analyst at Zeus Research, identified additional pressure from a shift of investor capital into traditional financial-market equities and large derivatives liquidations, with the breach of key price support levels in both Bitcoin and Ether intensifying losses as liquidation cascades forced further selling.
The outflow pattern across the ETF complex revealed selective investor behavior. While IBIT bore the brunt of the redemptions, Grayscale's GBTC posted $104.8 million in net outflows. Morgan Stanley's MSBT stood as the only major spot Bitcoin ETF to post net inflows during the period, capturing $4.3 million, suggesting a minor reallocation among Bitcoin ETF providers despite the broader market stress. These dynamics underscore the vulnerability of concentrated positions in Bitcoin ETFs to sharp price movements and market dislocations in derivatives markets.
