Bitcoin and Ethereum ETFs See Strong Inflows as Institutional Buyers Return Cautiously

Bitcoin and Ethereum spot ETFs posted strong weekly inflows as institutional investors returned, though analysts warn the trend needs time to hold.

Spot Bitcoin ETFs recorded their strongest inflow week in three months, pointing to renewed interest from institutional investors. Interestingly, this strong outing followed an early January outflow tied to tax positioning. 

Similar to BTC, Ethereum investment vehicles also posted solid gains. Recent data suggests market activity is returning through regulated products. And this comes even in the face of market volatility.

Bitcoin ETFs Attract $1.42B as Post-Tax Season Selling Fades

Bitcoin-related investment vehicles raised $1.42 billion between January 12 and January 16. According to market observers, this marked the fund’s strongest weekly performance since early October. During that period, BTC ETFs raked in about $2.7 billion. 

Fresh demand reversed outflows of roughly $1.3 billion to $1.4 billion recorded between January 6 and January 9. Experts linked this trend to year-end portfolio adjustments by institutions.

BlackRock led the rebound through its iShares Bitcoin Trust, which pulled in $1.035 billion. That figure accounted for nearly 73% of total weekly inflows. January 14 marked a record day for the fund, with $648.39 million added in a single session, the largest daily intake since its launch.

Fidelity followed as the second-largest contributor. Fidelity’s Wise Origin Bitcoin Fund recorded approximately $351.4 million in inflows on January 13, supporting the broader recovery across the ETF group. 

Combined buying lifted total assets under management across spot Bitcoin ETFs to about $128.04 billion, equal to 6.56% of Bitcoin’s total market value.

Key developments during the week included:

• Bitcoin ETF posted a weekly inflow of $1.42 billion.
• BlackRock’s iShares Bitcoin Trust captured over 70% of total inflows.
• January 14 saw the largest single-day Bitcoin ETF inflow of the year.
• Total BTC investments climbed above $128 billion.
• Early January outflows tied to tax positioning were fully reversed.

A three-day inflow streak stood out after December’s sharp pullback, when spot Bitcoin ETFs suffered a combined $4.57 billion outflow over two months. That stretch marked the worst period since ETFs launched in January 2024, raising concerns about sustained institutional demand.

BlackRock’s ETHA Leads $479M Inflow Week for Ethereum Spot ETFs

Ethereum spot ETFs also attracted fresh capital during the same period. Net inflows totaled $479 million from January 12 to January 16.

BlackRock’s ETHA led Ethereum products with $219 million in weekly inflows, pushing its cumulative total to $12.94 billion. Grayscale’s Ethereum Mini Trust followed with $123 million, bringing its historical net inflow to $1.63 billion.

The total net asset value of Ethereum spot ETFs reached $20.42 billion. ETF holdings now represent 5.14% of Ethereum’s market capitalization, while cumulative net inflows across all Ethereum ETFs stand at $12.91 billion.

Market Analysts Warn Bitcoin ETF Inflows Need Time to Confirm Trend Shift

Vincent Liu, chief investment officer at Kronos Research, said current patterns point to long-only allocators returning after weeks of caution. Speaking to Cointelegraph, Liu noted that ETF buying through regulated products signals renewed confidence. At the same time, on-chain data shows reduced selling by large holders.

According to Liu, whale activity has shifted since late December. Net selling by major holders has slowed, easing a key source of market pressure.

Combined ETF buying and reduced selling suggest available supply is becoming tighter even as prices remain volatile. Liu cautioned that the trend is still developing and does not yet confirm a lasting market shift.

Data from Ecoinometrics offered a more cautious view. The newsletter observed that recent spikes in spot Bitcoin ETF inflows have often triggered short-lived price rebounds rather than lasting rallies. 

Analysts argue that several consecutive weeks of strong inflows are needed to change the broader trend. They maintained that cumulative ETF flows remain deeply negative despite recent gains.
