Spot Bitcoin exchange-traded funds (ETFs) logged $1.42 billion in net inflows over the past week, marking their strongest weekly showing since early October as institutional interest rebounded.
Data from SoSoValue shows inflows were concentrated midweek, with Wednesday seeing the largest single-day net inflow of about $844 million, following roughly $754 million on Tuesday.
Although sentiment cooled toward the end of the week, including a $395 million net outflow on Friday, the heavy midweek buying lifted total weekly inflows to $1.42 billion. The last time spot Bitcoin ETFs posted stronger demand was in early October, when inflows reached $2.7 billion.
Ether ETFs followed a similar pattern, with inflows front-loaded earlier in the week. The largest single-day net inflow of approximately $290 million occurred on Tuesday, followed by around $215 million on Wednesday. Outflows later in the week, including roughly $180 million on Friday, reduced net weekly inflows to about $479 million.
Investors return as Bitcoin supply tightens
Vincent Liu, chief investment officer at Kronos Research, said the flow data points to long-only investors returning after a period of caution.
“ETF inflows suggest long-only allocators are re-entering the market through regulated vehicles,” Liu told Cointelegraph. “ETF absorption combined with whale stabilization indicates a tightening effective supply and a shift toward a more risk-on environment.”
Liu added that onchain data shows large holders, often referred to as whales, have scaled back net selling compared with late December, easing a major source of distribution pressure. Together with consistent ETF demand, this points to a market where available Bitcoin supply is tightening, even as price volatility remains.
However, Liu cautioned that the shift is still in its early stages and not yet definitive. “This is an early phase of the transition rather than full confirmation,” he said, adding that renewed inflows, lighter whale selling, and improving market structure suggest a more durable institutional bid is beginning to form beneath the surface.
“The odds favor more green days, though not in a straight line,” Liu added. “ETF inflows are creating a structural bid, while reduced whale selling means pullbacks are more likely to be absorbed.”
Short bursts of ETF inflows may not sustain Bitcoin rallies
According to the Bitcoin macro intelligence newsletter Ecoinometrics, recent surges in spot Bitcoin ETF inflows have typically fueled brief price rebounds rather than lasting rallies, with gains often fading as inflows slow.
The newsletter noted that Bitcoin likely needs multiple consecutive weeks of strong ETF demand to meaningfully shift the broader trend, pointing out that cumulative ETF flows remain firmly negative. While isolated inflow days can help stabilize prices, Ecoinometrics argued they are unlikely to support a sustained uptrend without consistent demand.
