US spot Bitcoin ETFs recorded a substantial $358.1 million in net inflows on Thursday, driven by a $269.3 million surge into BlackRock's iShares Bitcoin Trust (IBIT). This marks the strongest inflow day since early March, reversing a two-day net outflow trend.

Morgan Stanley's new Bitcoin Trust (MSBT) contributed $14.9 million on its second day of trading, while Fidelity's Wise Origin Bitcoin Fund (FBTC) attracted $53.3 million. Other ETFs, including VanEck, Franklin Templeton, Bitwise, and ARK 21Shares, also saw positive inflows.

Despite Bitcoin's price volatility, BlackRock's IBIT has secured $1.5 billion in net inflows this year. BlackRock notes IBIT investors are predominantly long-term holders. Morgan Stanley reported MSBT as its best-performing ETF launch historically.

The recent influx brings US spot Bitcoin ETFs close to reclaiming their annual net inflow targets, standing just $80 million shy of initial estimates.
