Morgan Stanley’s new spot Bitcoin ETF reached more than $139 million in assets within nine days. The early growth placed MSBT among the strongest ETF launches by the firm. It also showed demand for regulated Bitcoin products through large wealth platforms.
The fund opened with strong trading activity on April 8. It recorded $30.6 million in net inflows on its first day. By April 16, cumulative inflows had climbed to $116 million across seven sessions.

MSBT entered a crowded market, yet it posted a fast start. The fund averaged about $16.6 million in inflows per session. That pace made it Morgan Stanley’s strongest ETF debut so far.
The product also stood out on price. MSBT carries a 0.14% expense ratio. That fee is lower than other spot Bitcoin ETFs now trading in the United States.
The fund’s reach may also support future growth. Morgan Stanley has about 16,000 financial advisors. Those advisors manage access to a large pool of client assets across its wealth platform.
Still, the fund remains small beside larger rivals. The full U.S. spot Bitcoin ETF market holds more than $100 billion. BlackRock’s IBIT alone manages more than $53 billion.
Blockchain data added another view of the launch. Arkham Intelligence labeled wallets linked to MSBT held 1,348 BTC as of April 18. That amount was worth about $102 million at the time.
Recent deposits showed that the fund kept adding Bitcoin. More than $13 million in BTC arrived shortly before the April 18 snapshot. The wallet activity matched the pattern of steady net inflows seen in market data.
The fund offers investors Bitcoin exposure without direct custody. That structure removes private key handling and storage risks for many buyers. It also fits compliance rules used by advisors and wealth managers.
Morgan Stanley’s entry follows the wider rise of spot Bitcoin ETFs since early 2024. These products gave investors regulated access through brokerage accounts. That format has attracted both retail and institutional money.
MSBT’s next phase may depend on advisor adoption. Analysts have pointed to Morgan Stanley’s large wealth network as a possible growth engine. Broader use across that network could bring more assets over time.
Phong Le, President and CEO of Strategy, gave one estimate on X. He wrote, “”Morgan Stanley Wealth Management oversees about $8 trillion in AUM and recommends 0–4% bitcoin allocation.”” He added, “”A 2% allocation would represent $160 billion, about three times the size of IBIT.””
At the same time, the broader market has faced outflows. The spot Bitcoin ETF group has seen about $5 billion leave since November. On MSBT’s launch day, the wider category posted $93.9 million in net outflows.
Competition is also increasing. Goldman Sachs has filed for a Bitcoin Premium Income ETF. BlackRock is also working on income-focused Bitcoin products as firms seek new ways to attract assets.
