PANews reported on January 24 that Eric Balchunas, an ETF analyst at Bloomberg, tweeted that the Bitcoin spot ETF performed strongly in early 2025, with inflows of $4.2 billion, accounting for 6% of all ETF inflows. Since its launch, net inflows have exceeded $40 billion, with assets under management (AUM) reaching $121 billion and a yield of 127%. The AUM of the Bitcoin spot ETF has now exceeded that of the ESG ETF ($117 billion), and is comparable to the size of the gold spot ETF.

In contrast, the Ethereum ETF has only inflows of $130 million so far this year, showing that Bitcoin ETFs dominate the market. Even if more altcoin ETFs are launched in the future, their market share will still be difficult to compare with Bitcoin.
