According to Farside investors, BTC-spot ETF issuers recorded total net outflows of $144.8 million in the week ending May 30.
Despite net outflows of $430.8 million on May 30, BlackRock’s (BLK) iShares Bitcoin Trust (IBIT) still recorded weekly net inflows of $584.6 million, underscoring its dominant market position. Friday’s IBIT outflows were the first since April 9, reflecting the impact of trade developments on buyer appetite.
Bloomberg Intelligence Senior ETF Analyst Eric Balchunas remarked on IBIT’s dominance, stating:
“The IBIT vs Everyone Else flow disparity is interesting. Normally IBIT takes in 70% of the net inflows but lately it’s over 100%. My theory: the latest rally was more an institutional buying spree than retail (perhaps sparked by the decoupling and lessened vol).”
Balchunas estimated that institutional investors accounted for 10%, advisors 20%, and retail investors made up the remainder.
BTC-spot ETF market flows remain crucial for BTC’s supply-demand balance and price trajectory. In May 2025, issuers registered total net inflows of $5,232.1 million, supporting BTC’s climb to a May 22 record high of $111,917.
