Bitcoin and Solana spot ETFs see net outflows as Ethereum records inflows

On October 5, US spot crypto ETFs did something slightly awkward. Bitcoin and Solana funds posted net outflows. Ethereum funds posted net inflows.

XRP products, meanwhile, recorded no net flow at all.

The single-day snapshot is notable because it runs almost exactly opposite to the weekly picture. In the broader data, Bitcoin had been the clear favorite and Ethereum the one getting left on read.

The daily flip versus the weekly trend

Start with the daily numbers. Bitcoin and Solana spot ETFs both ended October 5 with more money leaving than arriving.

Ethereum ETFs went the other way, pulling in net new capital. XRP funds broke even, with zero net flow for the day.

Now zoom out. Data from SoSoValue, reported on October 5, showed US spot Bitcoin ETFs collected $241.09 million in weekly net inflows for the week ending in early October.

That marked the third straight positive week for Bitcoin funds. It also lifted cumulative inflows since the products launched in 2024 to around $57.8 billion.

Ethereum’s weekly picture looked far less cheerful. Spot Ethereum ETFs shed $138.02 million in net outflows over the same period.

That reversed the prior week, when Ethereum funds had taken in $690 million. The swing brought Ethereum ETF inflows for the year down to approximately $1.5 billion.

The smaller players: Solana, XRP and Zcash

According to the SoSoValue data, Solana spot ETFs gained around $2.43 million in weekly net inflows. XRP spot ETFs brought in $4.74 million for the week. Both figures extended existing inflow streaks for those products.

That context makes the October 5 Solana outflow more interesting. A fund on an inflow run posted a red day, even as its weekly tally stayed positive.

Then there is Zcash. Zcash ETFs recorded their first weekly outflow, totaling approximately $94 million, per the research covering late September through early October.

The backdrop: Bitcoin’s pull on capital

Bitcoin was trading near $85,000 to $86,000 during the period covered by the data.

The research framed the recent weekly pattern as a shift in investor sentiment, with capital appearing to favor Bitcoin over Ethereum as Bitcoin’s market dominance continued to build.

Spot Bitcoin ETFs have now accumulated around $57.8 billion in net inflows since their 2024 debut. Ethereum’s year-to-date total of approximately $1.5 billion is a much smaller figure by comparison.

What this means for investors

The weekly trend, per SoSoValue, still favored Bitcoin. Three consecutive weeks of inflows suggests steady demand rather than a sudden spike.

The research flagged that Ethereum’s outflows could raise concerns about its market position as it competes with Bitcoin for investor attention. If Ethereum funds string together several positive days, the weekly narrative could change quickly, much as the $690 million prior week showed demand can return fast.

For altcoin products more broadly, Solana and XRP kept their weekly inflow streaks, while Zcash posted its first outflow of approximately $94 million.

The research warned that continued rotation toward Bitcoin and other established assets could bring more volatility to the broader crypto market in the near term.
