Morgan Stanley's Bitcoin Trust ETF Amasses $50.6 Million in Two-Week Shopping Spree

Morgan Stanley's Bitcoin Trust ETF, MSBT, has been on an acquisition spree, scooping up approximately $50.6 million in Bitcoin through a series of transfers from Coinbase Prime over a two-week period in September 2026. This brings the total net assets to between $586 million and $635 million by mid-September, with cumulative net inflows exceeding $538 million since its launch on April 8, 2026.

The MSBT has recorded essentially no net outflows since its inception, with only a single day of net outflows in its entire history. The fund's first month set the tone, pulling in $193.6 million in net inflows across its initial 30 days. With a 0.14% expense ratio, it remains the cheapest spot Bitcoin ETF at launch.

The majority of inflows have been driven by self-directed clients, not Morgan Stanley's financial advisors. This suggests that investors are choosing to buy the ETF on their own, without a recommendation from a financial advisor. Coinbase Custody handles the actual Bitcoin storage, while BNY Mellon serves as administrator, and the fund tracks the CoinDesk Bitcoin Benchmark Rate.
