U.S. spot Bitcoin exchange-traded funds (ETFs) have reached a historic milestone, surpassing $100 billion in total net asset value as Bitcoin continues to hit record highs. According to SoSoValue, the combined assets of the 12 spot Bitcoin ETFs stood at $100.55 billion on Wednesday, representing 5.4% of Bitcoin’s total market capitalization.
The surge in assets was driven by Bitcoin’s recent price rally. The cryptocurrency, now trading at approximately $97,094, has seen a 3.8% increase over the past 24 hours, setting repeated all-time highs over the last few weeks.
Among the ETFs, BlackRock’s iShares Bitcoin Trust (IBIT) leads with $45.4 billion in net assets, followed by Grayscale’s Bitcoin Trust (GBTC) at $20.6 billion. Together, these two funds account for more than 65% of the total market share in spot Bitcoin ETFs.
Investor interest remains robust, with the 12 ETFs recording $733.5 million in net inflows on Wednesday. BlackRock’s IBIT dominated these inflows, attracting $626.5 million in fresh capital. Fidelity’s Wise Origin Bitcoin ETF (FBTC) followed with $133.9 million, while smaller contributions came from Bitwise’s Bitcoin ETF (BITB) at $9.3 million and Ark/21Shares’ ARKB at $3.8 million.
Trading activity also remained strong, with the 12 funds processing $5.09 billion in transactions on Wednesday. While this figure is slightly below Tuesday’s $5.71 billion, it underscores sustained investor engagement amid Bitcoin’s bull run.
In contrast, U.S. spot Ethereum ETFs have struggled, experiencing $30.3 million in net outflows on Wednesday, marking the fifth consecutive day of negative flows. Trading volumes for these funds also fell to $338.3 million from $345.1 million the previous day.
Bitcoin’s record-breaking rally and the growing adoption of spot ETFs reflect a broader trend of institutional and retail investors gravitating toward digital assets as they gain mainstream legitimacy. The milestone for Bitcoin ETFs highlights the expanding role of these products in providing exposure to the leading cryptocurrency.
