Morgan Stanley MSBT Hits $192M as BlackRock IBIT Options Eclipse Deribit in Bitcoin ETF Wars

Wall Street’s Bitcoin ETF arena just got a serious new contender. Morgan Stanley’s Morgan Stanley Bitcoin Trust (MSBT), launched in early April as the first spot Bitcoin ETF from a major U.S. bank, has already amassed $192 million in assets under management — and it’s coming for BlackRock’s crown. Meanwhile, BlackRock’s iShares Bitcoin Trust (IBIT) has hit a milestone of its own: its options open interest just surpassed Deribit, the offshore exchange that has dominated Bitcoin derivatives since 2016.

TL;DR

• Morgan Stanley enters the ring — MSBT launched in early April as the first spot Bitcoin ETF from a major U.S. bank, reaching $192 million in AUM with the market’s lowest fee at 0.14%.
• BlackRock’s options dominance — IBIT options open interest surpassed Deribit on April 25, with call options pointing to expectations of BTC near $109,709 in the near term.
• ETF fee wars intensify — MSBT’s 14-basis-point fee undercuts every competitor, pressuring BlackRock’s IBIT to consider fee reductions to maintain its $55 billion AUM leadership.

The MSBT Debut: A Bank-Branded Bitcoin Revolution

When Morgan Stanley Investment Management launched the Morgan Stanley Bitcoin Trust (MSBT) in early April 2026, it marked a watershed moment for institutional crypto adoption. For the first time, a bulge-bracket U.S. bank put its name on a spot Bitcoin ETF, signaling that the world’s largest wealth managers no longer view Bitcoin as a fringe asset but as a core portfolio allocation.

The early results have been striking. According to Bitcoin Magazine, MSBT accumulated over $139 million in BTC within its first nine days of trading. By late April, that figure had climbed to approximately $192 million in AUM, as reported by 24/7 Wall St., reflecting sustained demand from Morgan Stanley’s massive wealth management client base. The fund’s 0.14% expense ratio — the lowest in the spot Bitcoin ETF market — has been a key draw, undercutting established products from BlackRock, Fidelity, and Ark Invest.

BlackRock Fights Back: IBIT Options Eclipse Deribit

While Morgan Stanley makes waves on the fee front, BlackRock is extending its dominance in derivatives. On April 25, CoinDesk reported that IBIT options open interest topped Deribit for the first time — a seismic shift in the Bitcoin derivatives landscape. Deribit, the Panama-based exchange, has run the Bitcoin options market since 2016, but the migration of institutional hedging activity to regulated U.S. venues is now unmistakable.

According to data from Volmex, the bulk of open interest in IBIT call options points to expectations of the ETF rallying to levels equivalent to Bitcoin trading at $109,709 in the near term. That bullish positioning compares with a more measured outlook on Deribit, where options cluster around $106,000. The divergence suggests that U.S.-based institutional investors are significantly more optimistic about Bitcoin’s near-term trajectory than their offshore counterparts.

BlackRock’s IBIT remains the undisputed AUM leader at $55 billion, but the MSBT threat is real. Morgan Stanley brings something BlackRock cannot easily replicate: a captive distribution network of thousands of financial advisors managing trillions in client assets. If those advisors begin allocating even a small percentage of client portfolios into MSBT, the flow dynamics could shift rapidly.

By the Numbers

• $55 billion — BlackRock IBIT’s current AUM, making it the fastest-growing ETF in financial history.
• $192 million — Morgan Stanley MSBT’s AUM, achieved within weeks of launch with the market’s lowest fee at 0.14%.
• $109,709 — The Bitcoin price level implied by IBIT call options open interest, according to Volmex data.

The Fee War: Why 14 Basis Points Matters More Than You Think

MSBT’s 14-basis-point expense ratio is not just a marketing gimmick — it’s a calculated strike at the heart of the ETF competitive landscape. In the traditional ETF world, fee compression has been the primary driver of asset reallocation for over a decade. Funds that offered the lowest fees consistently attracted the most inflows, a pattern now repeating in the Bitcoin ETF space.

Analysts at 24/7 Wall St. identified three structural advantages that could allow MSBT to overtake IBIT: Morgan Stanley’s unrivaled wealth management distribution, its lowest-in-class fee, and the growing preference among advisors for bank-branded products when allocating client capital into volatile asset classes. The calculus is straightforward: if a Morgan Stanley advisor can choose between IBIT at 25 basis points or MSBT at 14 basis points, the incentive to recommend the in-house product is enormous — both for cost savings and for maintaining assets under the Morgan Stanley umbrella.

What the ETF Rivalry Means for Bitcoin’s Price Floor

The competitive dynamics between MSBT and IBIT have direct implications for Bitcoin’s price trajectory. Both funds generate programmatic buying pressure — every dollar of AUM represents Bitcoin that must be purchased and held by the fund’s custodian. As of late April, U.S. spot Bitcoin ETFs collectively logged eight straight days of inflows totaling $2.1 billion through April 23, pushing cumulative net inflows since launch to $58 billion, according to CoinDesk.

The addition of MSBT to this landscape means another institutional buyer is now competing for the same limited supply of Bitcoin. With Strategy holding 818,334 BTC, corporate treasuries and ETFs collectively controlling over 10% of circulating supply, and long-term holders refusing to sell, the structural supply squeeze is intensifying. The $58 billion in cumulative ETF inflows represents a permanent withdrawal of Bitcoin from the liquid market — and Morgan Stanley’s entry ensures that trend accelerates.

Why This Matters

For investors, the arrival of Morgan Stanley’s MSBT and the surge in IBIT options activity represent Bitcoin’s final transition from speculative asset to Wall Street infrastructure. When the world’s largest banks start competing on fees to offer Bitcoin exposure, the asset class has permanently arrived. The combination of MSBT’s low-fee disruption, IBIT’s options-driven price discovery pointing toward $109,000+ BTC, and $58 billion in cumulative ETF inflows creates a powerful demand floor. The question is no longer whether institutions will adopt Bitcoin — it’s which bank will capture the most assets.
