U.S. spot Bitcoin ETFs recorded $532.2 million in net inflows on May 4, marking a third consecutive trading day of positive flows as BTC climbed back above $80,000, according to data compiled by SoSoValue.
BlackRock‘s iShares Bitcoin Trust led the day with $335.5 million in fresh capital, followed by Fidelity‘s FBTC at $184.6 million. Notably, 10 of the 13 listed spot BTC funds registered zero flows on the day, concentrating institutional demand on the two largest issuers. No fund recorded outflows.
Monday’s tally extends a sharp rebound that began on May 1, when the segment absorbed $629.7 million — the strongest single-day inflow of 2026 so far. Cumulative net inflows into the 13 spot BTC ETFs have now reached $59.3 billion since their January 2024 launch, with total net assets at $106.4 billion as of Monday’s close, per SoSoValue.
The buying coincides with a broader risk-on rotation in crypto markets. BTC traded at $80,836 at time of writing, up 1.47% over 24 hours, while altcoins gained momentum and options desks positioned for further upside, according to a CoinDesk market note. BlackRock now holds over 810,000 BTC across roughly $50 billion in assets under management on the iShares trust.
Bloomberg ETF analyst Eric Balchunas pointed out on X that IBIT ranked 11th in April flows across the entire U.S. ETF universe with $2.3 billion, calling the figure a marker of long-term category viability despite a negative year-to-date return for the underlying asset. Daily ETF trading volumes have stayed above $1.4 billion, suggesting active rotation rather than passive accumulation. Whether the streak extends depends largely on macro flows: at least three banks have walked back rate-cut forecasts in the past week, but BTC has so far traded independently of that repricing.
