Crypto ETFs Surge as Bitcoin Funds Add $2.95 Billion in 30 Days

U.S. spot Bitcoin ETFs have seen substantial net inflows in the past month, drawing $2.95 billion over 30 days and continuing an eight-day run of positive daily flows, according to SoSoValue. Monday was the weakest day in the streak, with $31.07 million in net inflows, but the overall trend has been a rapid recovery following mid-September outflows. The inflow streak began on Sept. 17, two days after Bitcoin funds experienced a $450.4 million one-day exit that coincided with the Senate falling short on advancing the Clarity Act on Sept. 15. That same day, Ethereum ETFs lost $142.3 million. The week that included the failed vote produced just $6.2 million in net inflows for Bitcoin ETFs, the smallest weekly total in 141 weeks. Flows rebounded sharply later in the month. Sept. 21 recorded nearly $1 billion in inflows — the best single day since October 2025 — and Sept. 22 added another $715 million. Subsequent days were smaller but still positive, with Sept. 23 at $347 million, Sept. 24 at $191 million and Sept. 25 at $134 million, producing roughly $2.4 billion for that week, the largest weekly haul since October 2025. Fund-level activity on Monday showed BlackRock’s IBIT bringing in $54.84 million, while Grayscale’s GBTC and Fidelity’s FBTC posted outflows of $23.19 million and $10.90 million, respectively. The rally in ETF flows coincided with Bitcoin trading back above the average ETF holder cost basis of $81,722 and a price north of $84,000 on Monday. Other crypto ETFs also captured money over the 30-day window: Ether ETFs added $982.5 million, Solana funds $278.2 million, and XRP funds $127.05 million. The current eight-day run is close to a nine-day inflow streak recorded in August that ended on Aug. 28 after a $201.9 million outflow tied to remarks by Federal Reserve Chair Kevin Warsh at Jackson Hole.
