The iShares Bitcoin Trust ETF is part of a broader surge in U.S. spot Bitcoin ETF activity. These funds, including this trust, recorded their largest daily inflows in three months, with a single day seeing $750 million. This reversal from previous outflows is fueled by Bitcoin's price climbing above $95,000. The market for Bitcoin ETFs has grown to over $123 billion, with major institutions like Morgan Stanley, BlackRock, and Fidelity now participating, signaling strong institutional adoption and demand.
