BlackRock’s iShares Bitcoin Trust (IBIT) recorded a net outflow of approximately $285 million on May 13, 2026. This figure represents the fund's largest single-day redemption in three months.
The withdrawal contributed to a total net outflow of $635 million across all U.S. spot Bitcoin ETFs. IBIT maintained a trading volume of $1.5 billion on the same day.
The event suggests a potential increase in profit-taking or a shift in short-term institutional sentiment. This activity reverses a multi-week trend of steady inflows.
