According to new data from Bloomberg analyst Eric Balchunas, BlackRock’s Bitcoin ETF is now worth over $40 billion in total assets. This puts it in the top 1% of ETFs by AUM, but more importantly, it also crushes other ETFs in speed. The second-fastest ETF to hit $40 billion did so in 1,253 days, just barely faster than third place. IBIT did it in 211; that’s one-sixth the time.
