BlackRock’s iShares Bitcoin Trust Sets Record as Quickest ETF to Reach $70B AUM Amid Positive Flows

BlackRock's iShares Bitcoin Trust (IBIT) has become the fastest-ever ETF to reach $70 billion in assets under management (AUM), achieving this feat in just 341 trading days. This accomplishment is five times faster than the previous record set by the SPDR Gold Shares ETF. The fund’s AUM stands at $71.8 billion with 661,457 BTC. This rally is primarily driven by institutional investors, with IBIT seeing only three outflow days since April. Meanwhile, Bitcoin is currently trading at $110,000, a seven-fold return compared to the S&P 500. The sector overall, including eleven other spot Bitcoin ETFs, boasts almost $125 billion in AUM. Experts predict that BlackRock could surpass the largest Bitcoin holder, Satoshi Nakamoto, by mid-2026 if the positive inflows continue.
