The iShares Bitcoin Trust (IBIT) led a fourth consecutive day of capital withdrawals for U.S. spot Bitcoin ETFs on May 21, 2026.

IBIT recorded a net outflow of approximately $61.5 million on May 20. This figure accounted for the vast majority of the $70.5 million total that exited the sector that day.

The trend follows larger single-day redemptions recorded earlier in the week. Analysts suggest investors are trimming exposure and taking profits amid broader market uncertainty.

Market commentary also noted elevated hedging activity through put options on IBIT. These developments signal a growing cautious sentiment among institutional investors.
