Spot Bitcoin exchange-traded funds brought in $1.42 billion in net inflows over the past week, delivering their strongest weekly showing since early October as institutional interest resurfaced. Data from SoSoValue shows that inflows were concentrated earlier in the week, with Wednesday seeing the largest single-day net inflow of about $844 million, following roughly $754 million on Tuesday.

Although the latter part of the week saw some pullbacks, including a $395 million net outflow on Friday, the scale of the midweek inflows lifted the weekly total to $1.42 billion. That marks the best performance since early October, when weekly inflows reached approximately $2.7 billion.

Ether ETFs followed a similar pattern. Inflows were strongest at the start of the week, with around $290 million added on Tuesday and about $215 million on Wednesday. Later sessions were weaker, with Friday recording roughly $180 million in outflows, leaving Ether ETFs with net weekly inflows of about $479 million.

Supply dynamics and early institutional signals

Vincent Liu, chief investment officer at Kronos Research, said the flow data suggests that long-only investors may be returning after a period of caution.

“ETF inflows point to long-only allocators re-entering via regulated channels,” Liu told Cointelegraph. “ETF absorption alongside whale stabilization implies tightening effective supply and a more risk-on market environment.”

He noted that onchain indicators show large holders have eased net selling compared with late December, reducing a key source of supply pressure. When this moderation in whale activity is combined with consistent ETF buying, it points to a market where available supply may be tightening, even as price volatility remains elevated.

Liu stressed that the shift is still developing rather than definitive. “This is an early phase of the shift, rather than full confirmation,” he said, adding that renewed inflows, lower whale selling and improving market structure suggest a more resilient institutional bid may be forming beneath the surface.

“Odds point to more green days, though not in a straight line,” Liu said. “ETF inflows are providing a structural bid while easing whale selling suggests dips are more likely to be absorbed.”

Sustained demand seen as key for trend change

Not all analysts view short bursts of ETF demand as sufficient to drive a lasting rally. According to the Bitcoin-focused macro newsletter Ecoinometrics, recent surges in spot Bitcoin ETF inflows have often been followed by brief price rebounds that faded once inflows slowed.

The publication argues that a broader trend shift would likely require several consecutive weeks of strong ETF demand, noting that cumulative ETF flows remain firmly negative. While isolated inflow spikes may help stabilize prices in the near term, Ecoinometrics suggests that without sustained buying pressure, they are unlikely to support a durable upside trend.
