Morgan Stanley's spot Bitcoin ETF, MSBT, recorded $32.4 million in net inflows on September 23, making it the only U.S. Bitcoin ETF with positive flows that day. The latest inflow extended a three-session buying streak totaling $193.1 million, following approximately $61.7 million on September 21 and $99 million on September 22. MSBT has recorded no net outflow during its past 20 trading sessions. Launched in April 2026, the fund holds approximately 9,218 BTC worth about $775.75 million, according to the existing record. Its steady inflows contrast with more volatile flows across the wider U.S. spot Bitcoin ETF market and highlight Morgan Stanley's potential to channel demand from its advisory and wealth-management network.
