Best Spot Bitcoin ETFs: A Side-by-Side Comparison

A spot bitcoin ETF is a fund that holds real bitcoin and trades on a normal stock exchange, so you can buy it in the same account you use for shares. Thirteen of them now trade in the United States, and here is the part most comparison tables bury: they all hold the same asset, so none of them can beat the others on performance. What actually separates them is the annual fee, the size of the fund, and who stores the coins.

What does each fund charge?

In October 2026 the fees run from 0.14% to 1.50% a year. Morgan Stanley's MSBT is the cheapest at 0.14%, then Grayscale's Bitcoin Mini Trust (ticker BTC) at 0.15% and Franklin's EZBC at 0.19%. Bitwise's BITB charges 0.20% and ARK's ARKB 0.21%. The two biggest funds, BlackRock's IBIT and Fidelity's FBTC, both charge 0.25%. Grayscale's original trust, GBTC, still charges 1.50% - ten times the cheapest option for exactly the same bitcoin.

Does the size of the fund matter?

It matters for trading, not for safety. IBIT holds around $66bn and FBTC around $16bn; BITB and ARKB hold roughly $3bn each, and several funds hold under $500m. A bigger fund trades with a tighter spread - the gap between the price you buy at and the price you could sell at - so less of your money disappears on the way in and out. Think of a busy bureau de change at an airport terminal versus a quiet one in a side street: the same currency, a better rate where the queue is longer.

Who actually holds the bitcoin?

Most of these funds keep their coins at Coinbase. Fidelity is the main exception and stores FBTC's bitcoin in-house. That is worth knowing if you were planning to spread money across three ETFs for safety - three tickers can still mean one custodian, so the diversification is thinner than it looks.

Before buying, open the issuer's own fund page and read the current fee there, because these change and old articles go stale. Then check whether your broker charges a commission on the trade: a one-off $5 fee can cost more than a year of the difference between the cheapest fund and the most popular one.
