U.S. spot Bitcoin ETFs experienced a sharp one‑day withdrawal on Feb. 4, highlighting how concentrated ETF ownership can magnify downside in risk‑off moves. SoSoValue data show aggregate net outflows of -$544.94 million that day. Despite the pullback, cumulative net inflows remain substantial at $54.75 billion and total ETF net assets stand at $93.51 billion — about 6.36% of Bitcoin’s market capitalization.
Big fund flows were concentrated in a few products. BlackRock’s iShares Bitcoin Trust (IBIT) led the selloff with a one‑day net outflow of -$373.44 million; IBIT still holds roughly $56.21 billion in net assets and about $61.78 billion in cumulative inflows. Fidelity’s Wise Origin Bitcoin Fund (FBTC) saw -$86.44 million in withdrawals and now sits on $14.03 billion in net assets, with cumulative inflows near $11.19 billion; FBTC was trading essentially at NAV with a small -0.20% discount. Grayscale’s GBTC continued to register outflows (-$41.77 million on the day), leaving cumulative net outflows of -$25.80 billion and $11.60 billion in remaining net assets despite its 1.50% fee. Trading remained active, with total value traded in U.S. spot Bitcoin ETFs reaching $7.15 billion on Feb. 4.
Those ETF flows coincided with broader market risk‑off behavior. Bitcoin traded near $73,103, down roughly 5.5% over 24 hours, as the total crypto market cap fell about 4.4% to $2.35 trillion. Ethereum was around $2,111, oscillating between about $2,080 and $2,287 for the day on turnover near $47.4 billion. Solana hovered near $92 after a brief dip below $90, down roughly 7–8% on about $8.7 billion in volume.
Market strategists caution the ETF dynamic can work both ways. Citi strategists note that the average entry price for spot ETF buyers clusters near $81,600 and warn that slowing inflows combined with regulatory uncertainty could push Bitcoin toward the $70,000 area if outflows persist. The practical takeaway: high structural ETF ownership means flows can become a dominant driver of short‑term price moves, especially during cyclical demand pullbacks.
