Ethereum ETF inflows into U.S. spot Ethereum (CRYPTO:ETH) funds reached approximately $1.5 billion, surpassing the $985 million that spot Bitcoin (CRYPTO:BTC) ETFs brought in. This data, sourced from SoSoValue, shows daily crypto ETF inflows and outflows. Spot ETFs directly hold the coins, so their share prices rise and fall with the cryptocurrency’s market value.
Despite the higher inflow for Ethereum, Bitcoin ETFs still have a much larger market presence. Currently, Bitcoin funds manage around $109 billion in total assets, while Ethereum funds hold approximately $18 billion. This raises an important question: how can Ethereum’s 2026 inflows be impressive while Bitcoin ETFs remain six times larger?
Bitcoin ETFs Took In $6.3 Billion in the Third Quarter After a Weak First Half
Bitcoin’s annual figure for 2026 conceals a notable recovery. According to SoSoValue, Bitcoin ETFs recorded $6.3 billion in inflows during the third quarter alone—more than six times their total for the entire year. This surge occurred as Bitcoin marked its first winning quarter in a year.
Before July, Bitcoin funds experienced significant outflows, totaling about $5 billion more in withdrawals than new investments. This was particularly evident in late January, when a single day saw $818 million exit from the funds. The net flow, which reflects the amount of money coming in minus money going out, means that a strong quarter can easily disappear inside a subdued yearly total.
Bitcoin ETFs Have Gathered $57.6 Billion Since Launch, Four Times Ethereum’s Total
Over the years, Bitcoin ETFs have collected a staggering $57.6 billion in net inflows since their inception, whereas Ethereum funds have garnered $13.8 billion. Bitcoin ETFs began trading in January 2024—about six months before Ethereum funds, which debuted in July 2024.
At the current inflow rate, Ethereum funds are outpacing Bitcoin funds by about $525 million annually. However, it would take more than 80 years to close the existing $44 billion gap in total inflows.
Bitcoin’s Price Gains Nearly Doubled the Size of Its ETFs
The disparity in fund sizes also comes down to price appreciation. The value of the crypto assets within these funds affects their total assets. Bitcoin funds, currently valued at $109 billion, have gained about $52 billion since inception, driven by appreciation in their underlying coins. In contrast, Ethereum funds, valued at $18 billion, show a smaller gain of roughly $4 billion.
Both Bitcoin and Ethereum funds have declined from their highs earlier in 2026. Bitcoin fund assets peaked at $128 billion in mid-January 2026, while Ethereum funds hit $21 billion the same day. Since then, both funds have dropped by about 15%.
Why Are Bitcoin ETFs Still Six Times Bigger Despite Ethereum ETF Inflows?
Despite Ethereum ETFs attracting more inflows in 2026, Bitcoin ETFs’ larger size and recovery can’t be overlooked. Bitcoin funds remain six times larger, mainly because of earlier launches, higher net inflows, and greater price appreciation.
Current inflow data shows where new investments flowed in 2026, but it doesn’t fully reflect the relative sizes of the two fund groups. If Ethereum funds can surpass Bitcoin’s $6.3 billion third-quarter inflow in the fourth quarter, it could indicate a significant shift in investor interest. Conversely, if Bitcoin funds maintain their third-quarter momentum, their lead will only continue to grow by billions each quarter.
The ongoing performance of both asset classes will determine the future landscape of crypto investment.
