The Bitcoin ETF arena is witnessing a significant power shift. Morgan Stanley’s newly launched Bitcoin Trust (MSBT) is steadily attracting investor interest while BlackRock’s dominant iShares Bitcoin Trust (IBIT) has recorded a notable weekly outflow — signaling that the competitive landscape for spot Bitcoin ETFs is being redrawn in real time.
MSBT Posts Positive Flows as IBIT Breaks Its Winning Streak
Morgan Stanley Bitcoin Trust (MSBT) attracted a total of $10.81 million in net inflows from the start of the week through April 30. On Monday and Tuesday, MSBT posted zero net cash flow, but it currently holds Bitcoin worth approximately $197.7 million.
In contrast, BlackRock’s IBIT recorded a net cash outflow of $166.98 million during the same period, bringing its total Bitcoin holdings to approximately $61.11 billion at the time of publication.
Following IBIT’s cash outflow this week, the fund ended its 13 consecutive days of inflows — a notable streak that had built strong momentum for the world’s largest asset manager. Meanwhile, MSBT has never recorded a single net daily outflow since its inception, a remarkable consistency for such a new product.
Morgan Stanley’s MSBT: The Cheapest Bitcoin ETF on the Market
Morgan Stanley’s spot Bitcoin ETF began trading on April 8 under the ticker MSBT on NYSE Arca. It tracks the CoinDesk Bitcoin Benchmark 4 PM New York Settlement Rate and charges a 0.14% annual expense ratio — currently the lowest fee of any spot Bitcoin ETF on the market.
This pricing places immediate competitive pressure on BlackRock’s IBIT, which carries a 0.25% annual fee. The 11-basis-point difference may sound small, but at scale it is significant. On a $1 million allocation, an investor pays $1,400 per year with MSBT versus $2,500 with IBIT. For every $1 billion invested, the gap translates to $1.1 million in annual savings — a difference that large institutional allocators take very seriously.
MSBT also undercuts Grayscale’s Bitcoin Mini Trust, which charges 0.15%, making Morgan Stanley’s product the new cost benchmark across the entire Bitcoin ETP space.
A Record-Breaking Launch for Morgan Stanley
MSBT’s debut on April 8 was the strongest ETF launch in Morgan Stanley’s history across all asset classes. The fund logged more than 1.6 million shares traded and approximately $34 million in inflows on its very first day — all of this in a challenging market environment.
Within just six days of trading, MSBT surpassed $100 million in total assets under management. Amy Oldenburg, Morgan Stanley’s head of digital assets strategy, confirmed in a Bloomberg interview that MSBT had already become the firm’s most successful ETF launch ever.
The New York Stock Exchange described the debut as a new milestone in institutional access to digital assets, recognizing MSBT as the first spot Bitcoin ETF to be issued by a major U.S. bank. Coinbase and BNY were selected to provide digital asset custody and administration services for the fund, underlining its institutional-grade infrastructure.
Morgan Stanley’s Trillion-Dollar Distribution Advantage
What truly sets MSBT apart from other challengers to IBIT is not just the fee — it is the distribution muscle behind it. Morgan Stanley manages approximately $9.2 trillion in total client assets, primarily through its wealth management and advisory network. At the Bitcoin 2026 conference, Amy Oldenburg stated that the firm has been actively recommending investors allocate between 2% and 4% of their portfolios to Bitcoin. If even a fraction of that client base follows through, MSBT could theoretically attract hundreds of billions in new capital over time.
This is a fundamentally different competitive threat than IBIT has faced before. Previous challengers competed on price or brand alone. Morgan Stanley combines both — a lower fee and direct access to trillions in client capital through financial advisors who can now formally recommend Bitcoin as part of a diversified portfolio.
Can MSBT Dethrone IBIT?
BlackRock is not standing still. IBIT remains the most liquid Bitcoin ETF on the market with approximately $61 billion in assets, dominant trading volume, and a well-established options market. BlackRock manages nearly $14 trillion in assets globally, giving it deeper liquidity and a broader institutional footprint than Morgan Stanley.
Critically, BlackRock has not cut IBIT’s fee in response to MSBT’s launch, leaving Morgan Stanley’s cost advantage intact. Whether that changes in the coming months will be one of the most closely watched developments in the Bitcoin ETF space.
For now, this week’s data tells an interesting story. MSBT is gaining ground quietly and consistently. IBIT, for the first time in nearly two weeks, is losing ground. The Bitcoin ETF fee war has a new front-runner in pricing, and the race for institutional dominance in digital assets is very much alive.
The Bottom Line
Morgan Stanley’s entry into the spot Bitcoin ETF market has injected fresh competition into a space that BlackRock had largely dominated since January 2024. With the lowest fee in the category, a record-breaking debut, zero daily outflows since launch, and the backing of one of the world’s largest wealth management platforms, MSBT is positioned as the most credible challenger IBIT has ever faced. Whether it can close the enormous gap in assets under management remains to be seen — but this week’s flow data suggests the battle is just getting started.
