Bitcoin and ether ETFs record their best performance since October.

U.S.-listed exchange-traded funds linked to bitcoin and ether recorded a surge in inflows last week, delivering their strongest performance in roughly three months.

The 11 spot bitcoin ETFs collectively attracted $1.42 billion in net inflows, the largest weekly total since mid-October, according to TradingView data. BlackRock’s iShares Bitcoin Trust (IBIT) accounted for the majority of that demand, pulling in $1.03 billion.

Interest extended to ether products as well. Spot ether ETFs drew $479 million in net inflows, their best weekly showing since early October. BlackRock’s ETHA led the group with $219 million in new capital.

On a year-to-date basis, bitcoin ETFs have accumulated $1.21 billion in net inflows, while ether ETFs have taken in $584.9 million.

Analysts said most of the recent inflows represent outright bullish exposure, signaling a return of longer-term institutional capital. This marks a shift away from cash-and-carry arbitrage strategies—where investors pair long ETF positions with short CME futures—which have become less attractive as yields have declined.

Prices have responded to the renewed demand. Bitcoin has risen about 6% this month to around $92,600, while ether has gained nearly 8% to roughly $3,200, according to CoinDesk data.

“The close alignment between ETF flows and price action suggests institutional capital is actively shaping market structure, rather than passively following retail sentiment,” CoinDesk’s market insights model said. “This contrasts with late 2025, when bitcoin struggled to rally despite moderate ETF inflows.”

The model added that institutions appear to be positioning ahead of potential regulatory clarity and macroeconomic developments expected in the first quarter of 2026.

Still, analysts caution that sustained ETF inflows will be essential if bitcoin and ether are to post more meaningful gains in the months ahead, following the heavy outflows seen late last year.
