BlackRock's IBIT spot Bitcoin ETF has exceeded 700,000 BTC in assets under management after 18 months of trading, commanding about 56% of the total assets held by U.S. spot Bitcoin ETFs. This milestone highlights IBIT's dominance, outperforming competitors like Grayscale's GBTC, which has seen a significant decline in its Bitcoin holdings.

Strategy, formerly known as MicroStrategy, has purchased an additional 1,045 bitcoin for $110.2 million, increasing its total holdings to 582,000 BTC. The acquisitions were funded through the sale of its perpetual preferred stocks, and the company's total bitcoin investment now exceeds $40.8 billion, yielding significant paper gains.
