US Spot Bitcoin ETFs Draw $3.4B in Six-Week Inflow Streak

US spot Bitcoin exchange-traded funds recorded $3.4 billion in net inflows across six consecutive weeks through May, the longest positive streak since a seven-week run ended in July 2025, according to SoSoValue data.

The week ending April 17 anchored the streak with $996.38 million, the largest weekly inflow since mid-January. Daily inflows were particularly strong from April 30 through May 6; net inflows on May 1 reached $629.73 million.

The funds posted outflows on May 7 and May 8, shedding $277.50 million and $145.65 million, respectively, after a five-session string of daily inflows.

Other crypto exchange-traded products trailed Bitcoin over the same window. Ethereum ETFs recorded an $82.47 million outflow in the week ending May 1, then returned to inflows of $70.49 million the following week. XRP and Solana funds each logged weekly outflows in the week ending May 1.

Weekly inflows since April 2 averaged about $568 million. By comparison, the seven-week streak that ended July 25, 2025 averaged $1.51 billion per week and totaled $10.58 billion.

Whether the Bitcoin ETF streak extends to a seventh week will depend on net flows in the coming sessions. Fund-level data show daily flows can reverse quickly, and investors will be watching daily figures for signs of renewed inflows or continued outflows.
