Quick Insights

  • Morgan Stanley's MSBT completed its first month without a single day of net outflows, recording 17 inflow days and five flat days across 22 sessions since launching on 8 April.
  • The fund attracted $194 million in net inflows and grew assets to over $240 million, with Bloomberg ETF analyst Eric Balchunas placing the debut in the top 1% of all ETF launches ever.
  • On 7 May, one of the worst days for the sector, MSBT pulled in $5.7 million while Fidelity's FBTC lost $97.6 million, BlackRock's IBIT shed $27.2 million and ARKB saw $26.6 million in exits.
  • Nearly all first-month inflows came from self-directed clients. Morgan Stanley's 16,000 financial advisors have not yet been cleared to actively recommend the fund, meaning the advisor distribution channel is still to come.

Morgan Stanley's spot Bitcoin ETF finished its first month of trading on 8 May without a single day of net outflows, a flow profile no other US spot Bitcoin fund matched over the same period. MSBT attracted $194 million in net inflows and grew assets to over $240 million. Bloomberg senior ETF analyst Eric Balchunas ranked the debut in the top 1% of all ETF launches on record.

A Strong Open in a Week the Broader Market Was Bleeding

MSBT launched on 8 April with $30.6 million in net inflows and roughly $34 million in trading volume on day one, on a session when the broader spot Bitcoin ETF market posted $94 million in net outflows. Within six trading days it had crossed $103 million in cumulative inflows, passing the all-time total of WisdomTree's BTCW, a fund that had been trading since January 2024. Amy Oldenburg, Morgan Stanley's head of digital asset strategy, described it as the strongest ETF debut in the bank's history.

MSBT charges a 0.14% annual sponsor fee, the lowest among US spot Bitcoin ETFs, below Grayscale's Bitcoin Mini Trust at 0.15%, Bitwise at 0.20%, ARKB at 0.21% and both IBIT and FBTC at 0.25%. The difference is marginal for retail investors but translates to $1.1 million annually per $1 billion invested at institutional scale. Grayscale's Mini Trust, the closest fee comparison, posted at least one outflow day over the same window and saw smaller average daily inflows despite holding $4.3 billion in net assets.

On 7 May, a difficult session for the sector, MSBT recorded $5.7 million in inflows while Fidelity's FBTC saw $97.6 million in redemptions, BlackRock's IBIT shed $27.2 million and ARKB lost $26.6 million. The fund's flow data showed a 0.24% premium to net asset value, indicating demand was running ahead of new share creation.

Self-Directed Clients Drove All of It: The Advisor Channel Has Not Opened Yet

Almost all first-month inflows came from self-directed clients. Morgan Stanley's 16,000 financial advisors, who oversee more than $9.3 trillion in client assets, had not yet been cleared to recommend MSBT during its first weeks. Oldenburg confirmed that "almost all of that first week or two of activity was self-directed, meaning it was not our advisors that were selling this."

The bank is also planning to extend spot crypto trading to its ETrade platform, covering Bitcoin, Ethereum and Solana, which would add a separate distribution channel across more than 8 million users. Balchunas has projected MSBT could reach $5 billion in assets within its first year, a target that would require the advisory channel to open and accelerate meaningfully. The broader US spot Bitcoin ETF market drew more than $3 billion across six consecutive weeks of inflows through 8 May, the longest weekly streak since last summer, providing a supportive backdrop for the fund's launch period.
