Morgan Stanley’s Bitcoin Trust, ticker MSBT, scooped up another 83 Bitcoin on May 21, pushing its total holdings to 3,472 BTC. For a fund that only started trading on April 9, that’s a remarkably fast accumulation curve.

The data, sourced from Arkham Intelligence, paints a picture of consistent, deliberate buying. Not the kind of splashy one-time purchase designed to generate headlines, but the steady drip-drip-drip of an institution methodically building a position.

From zero to 3,472 in six weeks

MSBT debuted on the NYSE Arca on April 9, 2026, and hit the ground running. Initial net inflows came in at roughly $30.6 million, with trading volume touching approximately $34 million in its early days.

By late April, the fund held around 2,620 Bitcoin. That means it has added more than 850 BTC in the weeks since, a roughly 33% increase in holdings over less than a month.

The fund charges an expense ratio of just 0.14%, making it one of the cheapest spot Bitcoin ETFs on the market. For context, several competing products charge north of 0.20%, and some legacy funds still carry fees well above that.

Coinbase handles both custody and prime brokerage services for the trust.

Morgan Stanley’s Bitcoin evolution

Back in 2024, the bank began allowing its financial advisors to offer third-party Bitcoin ETFs to wealthy clients. Fast forward to April 2026, and the bank launched its own product. The shift from distributor to manufacturer is significant. When one of the world’s largest wealth management platforms decides it wants to own the entire value chain, from product creation to client distribution, it tells you something about where they see demand heading.

The fact that these additions are happening on what appears to be a near-daily basis tells you the inflows haven’t slowed down. Every time an investor buys shares of MSBT, the fund needs to go out and acquire the underlying Bitcoin.
