According to Wu, Arkham data shows that the combined assets under management (AUM) of BlackRock's two funds (IBIT and ETHA) are $21.6 billion, slightly higher than the $21.3 billion held by Grayscale's four funds (GBTC, BTC Mini, ETHE and ETH mini).

BlackRock’s crypto ETF now has the largest holdings of any provider. Nate Geraci, president of the ETF Store, noted that BlackRock’s IBIT spot Bitcoin ETF has only seen one day of net outflows since its launch.
