BlackRock’s iShares Bitcoin Trust (IBIT) has reached a major milestone, now holding

700,000 BTC with $76 billion in assets under management (AUM), according to Glassnode. Achieved in just 18 months, this milestone places IBIT ahead of prominent ETFs like the iShares Core S&P 500 ETF (IVV) and iShares Russell 2000 ETF (IWM).

Launched in January 2024, U.S. spot Bitcoin ETFs have quickly become the most successful ETF rollouts in history, attracting over $50 billion in net inflows. IBIT has led this growth and is now BlackRock’s third-highest revenue-generating ETF among its 1,197 products.

By comparison, MicroStrategy (MSTR), which began accumulating Bitcoin in 2020, holds around 600,000 BTC, while Fidelity’s FBTC holds 203,000 BTC and Grayscale’s GBTC holds 184,000 BTC.

“This is a remarkable achievement—700,000 BTC in 18 months,” said Nate Geraci, President of The ETF Store, in a post on X.#BTC $BTC
