US spot Bitcoin ETFs post 6th straight week of net inflows, longest streak in nine months
US spot Bitcoin exchange-traded funds extended their run of weekly net inflows to six consecutive weeks, the longest stretch of net buying since August 2025. Figures tracked by SoSoValue show roughly $3.4 billion of net additions over the six-week period, signaling renewed demand for regulated, spot BTC exposure even as intraday trading in Bitcoin remains volatile.
Within the series that began around the week of April 2, inflows were strongest in mid-April. The week of April 17 recorded the largest weekly intake at $996.38 million, and the latest week added $622.75 million. The softest week in the six-week sample started with about $22.34 million in inflows.
The latest week was uneven on a day-to-day basis. After a strong start—$532.21 million on Monday and $467.35 million on Tuesday—inflows slowed to $46.33 million on Wednesday. The week then ended with notable redemptions: $277.50 million of outflows on Thursday and $145.65 million on Friday.
The six-week streak is the longest in more than nine months. The prior longer run lasted seven weeks from June 13 to July 18, 2025, bringing in about $7.57 billion in total, including $2.72 billion during the week of July 11 and $2.39 billion the following week.
Ether ETFs also turned positive
Ether ETFs moved back into net inflows for the week ending May 8, posting $70.49 million after a prior period of net outflows totaling $82.47 million. Earlier in April, Ether products saw a three-week run from April 10 to April 24 that generated $617.91 million of combined inflows, peaking at $275.83 million in the week of April 17.
Daily flows for Ether ETFs in the May 8 week were volatile: Monday and Tuesday saw inflows of $61.29 million and $97.57 million, Wednesday added $11.57 million, Thursday saw $103.52 million in outflows, and Friday recovered by $3.57 million—leaving the week modestly positive.
Market context
Overall, the flow data points to steady—though not linear—demand for regulated crypto exposure through ETFs. Persistent Bitcoin inflows suggest many investors continue to view spot BTC exposure as a portfolio hedge or diversification tool, even as choppy price action and broader liquidity conditions create short-term volatility. The macro backdrop remains uncertain, with markets watching key US data releases and ongoing geopolitical developments that can shift risk appetite and liquidity.
What to watch
In the weeks ahead, ETF flow momentum will likely hinge on domestic macro signals and the evolving geopolitical environment. Continued inflows could keep ETF-linked BTC demand influential, particularly as institutions pursue regulated access. At the same time, late-week reversals highlight the need for disciplined risk management among ETF traders and market makers. Investors will also be watching Ether ETF flows for confirmation of a broader reset in demand following the mid-April surge and early-May rebound.
