Morgan Stanley launched the Morgan Stanley Bitcoin Trust (MSBT) on April 8, setting its expense ratio at 0.14 percent and positioning it as the lowest-cost U.S. spot Bitcoin ETF available. This development brings fresh attention to ongoing fee competition within the growing sector of Bitcoin exchange-traded funds as institutional interest in these products continues to rise.
Analysts see IBIT’s dominance intact for now
MSBT’s market entry drew immediate attention among ETF analysts after attracting roughly $30.6 million in net inflows on its first trading day and processing over 1.6 million shares. ETF analyst Eric Balchunas noted this debut places MSBT among the top one percent of all ETF launches on record by trading volume and asset inflows.
Balchunas anticipates that MSBT could reach $5 billion in assets under management within its first year if momentum holds. Despite this, he assessed that BlackRock’s iShares Bitcoin Trust (IBIT) remains firmly established as the dominant U.S. spot Bitcoin ETF. IBIT presently manages around $55 billion in assets, far ahead of its competitors.
The liquidity commanded by IBIT creates advantages for institutional traders, such as tighter spreads and a deeper options market. These attributes lead many investors to continue prioritizing IBIT, even as new low-fee options enter the market.
From Balchunas’s perspective, BlackRock is unlikely to reduce IBIT’s fees at this stage. In a post about MSBT’s entry, he remarked:
“Prob won’t see any cut from $IBIT. When you are King of the Hill with tons of liquidity, you have pricing power,” Balchunas observed.
Bloomberg ETF analyst James Seyffart expressed a similar view, suggesting that MSBT is unlikely to challenge IBIT on liquidity in the near term.
Implications for competition and market structure
While IBIT’s fee structure may remain steady, the launch of MSBT is expected to increase pressure on smaller issuers. Balchunas indicated that other firms with lower market share and scale could soon be compelled to cut fees in response to Morgan Stanley’s aggressive pricing.
With all spot Bitcoin ETFs holding the same underlying asset, cost is emerging as a key factor in differentiating between products. MSBT’s expense ratio undercuts Grayscale’s Bitcoin Mini Trust, now at 0.15 percent, and is considerably below Fidelity’s Wise Origin Bitcoin Fund, which sits at 0.25 percent.
Morgan Stanley’s wealth management division provides a strategic distribution advantage that most competitors lack. The firm employs approximately 16,000 financial advisors, overseeing $9.3 trillion in client assets. With their own ETF on the market, these advisors now have an in-house solution to offer clients seeking Bitcoin exposure.
According to Balchunas, only two scenarios might prompt BlackRock to review IBIT’s pricing: a sustained shift of capital away from IBIT to lower-cost rivals, or the entry of a new provider like Vanguard with a much lower expense ratio—though he assessed the likelihood of the latter as extremely remote.
The U.S. spot Bitcoin ETF market crossed $100 billion in cumulative assets since its start in January 2024, highlighting rapid growth. While 2026 began with several months of industry-wide net outflows, March saw an influx of $1.32 billion, suggesting renewed investor interest.
Looking ahead, MSBT’s initial momentum and its ability to attract sustained inflows may determine if other issuers adjust their strategies—or if IBIT’s fee position remains unchallenged in the rapidly evolving landscape.
