U.S. spot Bitcoin ETFs pulled in more than $1 billion in inflows this week through Thursday, marking the first time since January that weekly inflows have crossed the billion-dollar threshold, and BlackRock’s iShares Bitcoin Trust (IBIT) captured the lion’s share.

Over the past three days, IBIT has recorded around $721.5 million in inflows,  according to Farside Investors data. It's the largest spot Bitcoin ETF in the market, with over $66 billion in assets under management. The only other funds to see inflows this week were Ark Invest’s ARK 21Shares Bitcoin ETF (AKRB), which recorded around $92.3 million, and the newly launched Morgan Stanley Bitcoin Trust (MSBT), which logged around $12.2 million.

BlackRock’s IBIT Dominates Bitcoin ETF Inflows

On Wednesday alone, IBIT drew in $134.6 million, the only Bitcoin spot ETF to see inflows on the day. On the other side of the ledger, the Fidelity Wise Origin Bitcoin Fund (FBTC) posted the largest outflows, amounting to around $38.95 million, followed by the Bitwise Bitcoin ETF (BITB), with redemptions exceeding $25 million.

IBIT’s price edged 0.6% lower in pre-market trade alongside the selloff in cryptocurrency markets. Bitcoin (BTC) fell over 2% in the last 24 hours to below $81,000. Retail sentiment around IBIT and Bitcoin on Stocktwits trended in ‘bullish’ territory over the past day, accompanied by ‘high’ levels of chatter.

Bitcoin ETF Assets Climb Back Above $101 Billion

The influx of capital comes after April set the stage. Spot Bitcoin ETFs pulled in $2.44 billion last month, the strongest monthly figure since October 2025, when Bitcoin hit its $126,000 all-time high. IBIT alone captured $1.71 billion of that total, a 70% market share that continues to widen the gap between the fund and every other ETF in the space. 

Total net assets across spot Bitcoin ETFs also pushed back above $101 billion at the end of April, with inflows coinciding with Bitcoin trading above $80,000 for the first time since January.
