Morgan Stanley's MSBT ETF buys $52M in Bitcoin, sees no outflows

Morgan Stanley's spot Bitcoin ETF has been on a shopping spree. The Morgan Stanley Bitcoin Trust, ticker MSBT, scooped up roughly 642 BTC worth approximately $50.6 million through a series of transfers from Coinbase Prime over a two-week stretch in September 2026. And in a detail that would make any fund manager jealous, the product has recorded essentially no net outflows since its April launch.

The MSBT has pulled in cumulative net inflows exceeding $538 million, pushing its total net assets to somewhere between $586 million and $635 million by mid-September. For a product that represents Wall Street's old guard tiptoeing into Bitcoin territory, those numbers are more than a toe.

Morgan Stanley launched MSBT on April 8, 2026, making it the first spot Bitcoin ETF from a major US bank-affiliated asset manager.

The fund's first month set the tone. MSBT pulled in $193.6 million in net inflows across its initial 30 days, with only a single recorded day of net outflows in its entire history.

The product charges a 0.14% expense ratio, which made it the cheapest spot Bitcoin ETF at launch. Coinbase Custody handles the actual Bitcoin storage, while BNY Mellon serves as administrator. The fund tracks the CoinDesk Bitcoin Benchmark Rate.
