Spot Bitcoin ETFs Draw Nearly $1 Billion in Weekly Inflows, Best Since January

• Spot Bitcoin ETFs attracted $996.4 million in net inflows last week, the highest weekly total since the week ended Jan. 16.
• BlackRock’s IBIT led the surge with $906 million, while spot Ethereum ETFs also recorded their strongest weekly inflows since mid-January.

Spot Bitcoin ETFs have put together their strongest week in months, drawing just under $1 billion as institutional demand appears to be firming again.

According to said from SoSoValue, U.S. spot Bitcoin ETFs logged $996.4 million in net inflows last week, the largest weekly total since the week ended Jan. 16. Over the past three weeks, those funds have now taken in more than $1.8 billion, a pace that suggests the category is regaining momentum after a quieter stretch.

BlackRock again carried most of the flow

The headline number was large, but the composition matters too. BlackRock’s IBIT, still the biggest Bitcoin fund by net assets, accounted for the vast majority of the weekly intake, pulling in $906 million on its own.

That concentration says something familiar about the ETF market. When investors return to crypto exposure through traditional wrappers, the flows often move first and hardest into the most established products. Scale, liquidity and brand recognition still matter, perhaps more than the broader count of available funds.

The week also marked the first full trading stretch for Morgan Stanley’s MSBT, which launched on April 8. The new fund posted $71 million in weekly net inflows, a respectable start for a late entrant in an increasingly competitive market.

Ethereum ETFs joined the rebound

The buying was not limited to Bitcoin. Spot Ethereum ETFs also recorded their strongest week since Jan. 16, bringing in $275.8 million in net inflows.

That broader pickup is worth watching. Bitcoin ETF demand has, for much of the year, looked more stable than Ethereum’s. A simultaneous rise in both categories may suggest institutions are becoming more comfortable adding crypto risk across the major asset layer, rather than treating Bitcoin as the only acceptable entry point.

For now, the flow data points in one direction. After a softer period, ETF demand is picking up again, and the scale of last week’s inflows suggests that traditional capital is not stepping away from crypto exposure. It may simply have been waiting for a cleaner moment to add again.
