MSBT: The 'Monster' ETF That Wants to Gobble BlackRock's IBIT Like a Midnight Snack

Strategy CEO Phong Le thinks the market is snoozing on Morgan Stanley's upcoming spot Bitcoin ETF. He's betting the bank's wealth-management arm, which babysits a cool $8 trillion in assets, could casually yeet BlackRock's iShares Bitcoin ETF (IBIT) off the top spot without breaking a sweat.

The bank currently suggests clients might want to allocate between 0% and 4% of their portfolio to Bitcoin. Hitting the sweet spot of 2% would mean a staggering $160 billion exposure – enough to swallow IBIT's current $55 billion AUM three times over and still have room for a side of memecoins, dwarfing its $63 billion total inflow.

Since the U.S. spot BTC ETFs first hit the scene in early 2024, Morgan Stanley has been playing the ultimate middleman, gently steering its advisors toward other people's products like IBIT and collecting those sweet, sweet commission crumbs. By Q3 2025, IBIT was coughing up nearly $191 million in management fees, making it the third-biggest cash cow in BlackRock's entire ETF stable.

A few moons later, Morgan Stanley filed (and then re-filed, because the SEC loves paperwork) for its own BTC ETF, tentatively named MSBT. Getting the green light would let the bank feast on both the distribution and management fees, becoming the first U.S. bank to serve a Bitcoin ETF directly from its own kitchen.

Amy Odelnburg, Morgan Stanley's head of crypto, notes that adoption is still in its "connecting a hardware wallet" phase, with most demand coming from self-directed degens rather than accounts managed by wealth advisors. In fact, a solid 80% of the platform's ETF distribution flows through the self-directed channel, where investors presumably do their own research.

The firm isn't stopping at just an ETF plate; it's eyeing the whole crypto buffet, with plans for BTC lending, trading, and custody services to expand its menu far beyond a single financial instrument.

Not everyone is buying the hype. Joe Takayama of Backpack suggests that the $160 billion demand projection might be a bit too hopium-fueled, cautioning that real-world allocations could easily dip far below 2% or, in a classic "risk-off" move, round down to a big fat zero.

Adding a splash of cold water to the narrative, the early-March rally in BTC ETFs has since face-planted, with three straight days of outflows. Ongoing macro headwinds and a general "sell everything" mood among ETF investors could put the brakes on Bitcoin's recovery, which, at press time, is chilling at $70K.
