CoinVoice has learned that senior ETF analyst Eric Balchunas from Bloomberg posted performance data for 2025 exchange-traded funds (ETFs) on the X platform, showing that last year the assets under management (AUM) of ETFs reached a record $1.48 trillion (nearly $60 billion per day), a 28% increase from the previous year.

Among them, BlackRock's Bitcoin ETF IBIT has an AUM of approximately $248.44 billion, ranking sixth. However, due to Bitcoin's overall poor performance last year, BlackRock IBIT was the only ETF among the top 15 with a negative annual return, at -6.41%.
