BlackRock’s spot Bitcoin ETF IBIT was the best performer among the Bitcoin ETFs and also among all the nearly 4,000 exchange-traded funds on a list made by Bloomberg ETF analyst James Seyffart. The fund has over $52 billion in AUM. Meanwhile, Fidelity’s Bitcoin ETF FBTC took fourth place, with nearly $20 billion in AUM one year after its launch. ARKB, the spot Bitcoin ETF managed by 21shares and ARK Invest, stood at 16th place with $4.4 billion in AUM. Bitwise’s BITB wrapped Bitcoin ETFs in the top 20 in 18th place, with roughly $4 billion in AUM.Seyffart highlighted that BITB and ARKB, managed by relatively small asset managers, were among the top 20 launches last year. Expanding the list to the top 100 launches, VanEck’s Bitcoin ETF HODL makes the cut with its $1.3 billion in AUM, securing the 99th place.Over 4% of global flowsThe two largest spot Bitcoin ETFs by net flows, IBIT and FBTC, represented over 4% of the global $1,14 trillion flows. Both funds ranked among the top 20, with IBIT being bested only by two traditional finance giants: the iShares Core S&P 500 ETF (IVV) and the Vanguard S&P 500 ETF (VOO).Another significant milestone was surpassing gold ETFs in their first year. According to Bitwise, gold ETFs registered approximately $2.5 billion in flows in their launch year, while US-traded Bitcoin ETFs secured over $37 billion in inflows.In their best year, gold ETFs inched closer to $30 billion in inflows, which is way below what Bitcoin ETFs registered in their first year.Furthermore, in mid-December, the cumulative AUM of all Bitcoin ETFs—including spot, derivatives, and leverage—surpassed the total AUM of gold ETFs.Notably, according to Farside Investors’ data, despite a significant outflow of nearly $570 million on Jan. 8, US-traded spot Bitcoin ETFs still registered $462 million in positive net flows this week before closing on Jan. 10.Mentioned in this article
