Morgan Stanley Moves Closer to Spot Bitcoin ETF Debut After Amendment No. 4

TLDR

• Morgan Stanley filed Amendment No. 4 for the Morgan Stanley Bitcoin Trust on April 1, 2026.
• MSBT proposes a 0.14% management fee, below other U.S. spot Bitcoin ETFs.
• Coinbase Custody is named as Bitcoin custodian for the trust.
• BNY Mellon will serve as cash custodian, administrator and transfer agent.
• The trust plans an initial seed basket of 50,000 shares worth about $1 million.

Morgan Stanley has filed Amendment No. 4 for its proposed Morgan Stanley Bitcoin Trust, a move that places the product closer to a possible market debut on NYSE Arca. The filing, dated April 1, 2026, is being treated by market participants as one of the final procedural steps before trading can begin, subject to the remaining regulatory process.

The proposed fund would enter the U.S. spot Bitcoin exchange-traded fund market with a management fee of 0.14%, according to the latest filing details. That fee would place the Morgan Stanley Bitcoin Trust, expected to trade under the ticker MSBT, below the current low-cost products in the segment, including the Grayscale Bitcoin Mini Trust at 0.15%. It would also come in below larger spot Bitcoin ETF competitors such as BlackRock’s iShares Bitcoin Trust and Fidelity’s Wise Origin Bitcoin Fund, both of which charge 0.25%.

The latest amendment also includes operational updates tied to custody, share creation mechanics and trust structure. Reports on the filing said these changes reflect SEC feedback received during the review process. The trust is expected to begin with an initial seed basket of 50,000 shares, aimed at raising about $1 million at launch.

Fee strategy puts Morgan Stanley near the front of the market

The proposed 0.14% management fee has drawn immediate attention because pricing remains a central factor in the U.S. spot Bitcoin ETF market. Since the first wave of spot Bitcoin ETFs entered trading, issuers have competed on cost, liquidity, brand reach and distribution. Morgan Stanley’s filing positions the bank to enter that contest with the lowest stated fee among comparable U.S. products.

A lower fee can matter for investors comparing long-term holding costs across Bitcoin funds with similar structures. Based on the fee table reported alongside the filing, Morgan Stanley would rank ahead of Grayscale Bitcoin Mini Trust, Franklin Bitcoin ETF, Bitwise Bitcoin ETF and ARK 21Shares Bitcoin ETF on annual expense ratio. Grayscale Bitcoin Trust, which remains one of the highest-fee products in the category, is listed at 1.50%.

Morgan Stanley’s filing also drew attention because the bank is not entering the market only as a distributor. If the trust is approved and launched, Morgan Stanley would become the first major U.S. bank to directly issue its own spot Bitcoin ETF. Large financial institutions have already played roles in custody, brokerage and wealth platform access for digital asset products, but issuing a house-branded fund would mark a different step in market participation.

Custody and distribution details come into focus

The amendment identifies Coinbase Custody as the trust’s Bitcoin custodian. BNY Mellon is listed as cash custodian, administrator, and transfer agent. Those assignments place core fund operations with firms already active in ETF servicing and digital asset infrastructure.

The filing also matters because of Morgan Stanley’s existing wealth management network. The bank’s adviser platform includes about 16,000 advisers, according to the information provided, giving the firm a built-in channel for product distribution if the trust begins trading. Market observers have linked that internal network to potential demand, especially as digital asset allocations continue to be discussed within diversified portfolios.

Morgan Stanley has already been associated with crypto allocation guidance for clients, with reported recommendations of 2% to 4% exposure in some portfolio discussions. A bank-issued Bitcoin ETF with a lower fee could become part of that offering, depending on internal platform decisions and investor suitability requirements.

Launch watch grows as spot Bitcoin ETF market expands

Industry attention is now focused on the potential launch timeline. Reports tied to the filing said trading could begin as early as April 8, 2026, though the final date remains tied to the completion of regulatory and exchange procedures. Amendment No. 4 is being viewed as a late-stage filing, which often signals that a product is moving closer to the market.

The U.S. spot Bitcoin ETF segment has continued to expand as issuers compete for assets by offering pricing and access advantages.

Morgan Stanley’s proposed Bitcoin Trust adds another major financial brand to the field and does so with a fee structure aimed at the lower end of the market. With custody, administration and exchange listing details now more clearly laid out, the focus has shifted to whether MSBT becomes the next spot Bitcoin fund to start trading on NYSE Arca.
