Spot Bitcoin ETF AUM Hits Lowest Level Since April 2025

Assets in spot Bitcoin (BTC) ETFs slipped below $100 billion on Tuesday following a fresh $272 million in outflows.

According to data from SoSoValue, the move marked the first time spot Bitcoin ETF assets under management have fallen below that level since April 2025, after peaking at about $168 billion in October.

The drop came amid a broader crypto market sell-off, with Bitcoin sliding below $74,000 on Tuesday. The global cryptocurrency market capitalization fell from $3.11 trillion to $2.64 trillion over the past week, according to CoinGecko.

Altcoin funds secure modest inflows

The latest outflows from spot Bitcoin ETFs followed a brief rebound in flows on Monday, when the products attracted $562 million in net inflows.

Still, Bitcoin funds resumed losses on Tuesday, pushing year-to-date outflows to almost $1.3 billion, coming in line with ongoing market volatility.

By contrast, ETFs tracking altcoins such as Ether (ETH), XRP (XRP) and Solana (SOL) recorded modest inflows of $14 million, $19.6 million and $1.2 million, respectively.

Is institutional adoption moving beyond ETFs?

The ongoing sell-off in Bitcoin ETFs comes as BTC trades below the ETF creation cost basis of $84,000, suggesting new ETF shares are being issued at a loss and placing pressure on fund flows.

Market observers say that the slump is unlikely to trigger further mass sell-offs in ETFs.

“My guess is vast majority of assets in spot BTC ETFs stay put regardless,” ETF analyst Nate Geraci wrote on X on Monday.

Thomas Restout, CEO of institutional liquidity provider B2C2, echoed the sentiment, noting that institutional ETF investors are generally resilient. Still, he hinted that a shift toward onchain trading may be underway.

“The benefit of institutions coming in and buying ETFs is they’re far more resilient. They will sit on their views and positions for longer,” Restout said in a Rulematch Spot On podcast on Monday.

“I think the next level of transformation is institutions actually trading crypto, rather than just using securitized ETFs. We’re expecting the next wave of institutions to be the ones trading the underlying assets directly,” he noted.
