Bitcoin ETF Comparison 2026
IBIT vs FBTC vs ARKB vs MSBT

The market leader by a significant margin. IBIT has accumulated over $55 billion in assets since launching in January 2024 — making it one of the fastest-growing ETFs in history. BlackRock is the world's largest asset manager with $10 trillion under management, and their institutional relationships have driven enormous inflows from pension funds, endowments, and wealth managers.

Expense ratio: 0.25%. Not the cheapest, but the liquidity advantage more than compensates for most investors. Daily trading volume exceeds $2.8 billion — meaning you can buy or sell large positions without moving the price.

Options market: IBIT has the deepest and most liquid Bitcoin ETF options market, making it the default choice for investors who want to hedge or generate income from their Bitcoin position.

Custodian: Coinbase Custody Trust — the largest regulated crypto custodian in the US. This is a point of concentration risk — IBIT, ARKB, and several other ETFs all use Coinbase as custodian.

The only major ETF where the issuer custodies its own Bitcoin. While IBIT and ARKB rely on Coinbase Custody, Fidelity Digital Asset Services — Fidelity's own subsidiary — holds the Bitcoin for FBTC. For investors concerned about Coinbase concentration risk across the ETF market, this is a meaningful differentiator.

Expense ratio: 0.25%. Same as IBIT. The custody advantage comes at no extra cost.

Fidelity integration: If you already have a Fidelity brokerage account, FBTC offers seamless integration with your existing portfolio, reporting, and tax documents all in one place.

AUM ~$22 billion — the second largest spot Bitcoin ETF. Highly liquid with strong institutional backing from Fidelity's 77-year track record and 40 million customer relationships.

The lowest-fee option among the established ETFs at 0.21% — slightly below IBIT and FBTC's 0.25%. For long-term holders who don't trade frequently, this fee difference compounds meaningfully over years.

Launched by ARK Invest and 21Shares — a collaboration between Cathie Wood's ARK, known for its strong Bitcoin conviction and long-term innovation thesis, and 21Shares, a European digital asset specialist with deep ETF experience.

AUM ~$3.6 billion — smaller than IBIT and FBTC but still highly liquid for most retail investors. Daily volume around $86 million means most positions can be executed efficiently.

Custodian: Coinbase Custody — same as IBIT. For investors specifically concerned about Coinbase concentration risk, FBTC remains the alternative.

Brand new — launched April 8, 2026. MSBT is the first spot Bitcoin ETF issued by a major US bank — a significant milestone that signals mainstream traditional finance fully embracing Bitcoin as an investable asset class.

The lowest expense ratio in the market at 0.14% — below even the Grayscale Mini Trust's 0.15%. Morgan Stanley is clearly using fee competition to attract assets from IBIT and FBTC. Over a 10-year holding period, the 0.11% fee difference versus IBIT compounds to meaningful savings on larger positions.

Morgan Stanley's distribution advantage is real. The firm manages roughly $9.3 trillion in client assets and operates one of the largest financial advisor networks in the US. That reach into wealth management clients who prefer accessing Bitcoin through advisors rather than direct trading could drive significant inflows over time.

The caveat — it's very early. With only ~$100 million in AUM after its first two weeks, MSBT has very low liquidity compared to IBIT's $55 billion. Bid-ask spreads will be wider and large orders may move the price. For most retail investors today, the fee savings don't yet justify the liquidity tradeoff. Watch this one closely through 2026.
