BITO is a registered fund that reaches Bitcoin through what its N-PORT for Aug 31, 2026 lists: Bitcoin futures and swaps on Bitcoin. Over the year to Oct 28, 2026, Bitcoin moved −28.3% and BITO returned −30.5%. That leaves it 2.2 percentage points behind.

A holder gets exposure to Bitcoin without the fund holding the coin itself. That difference is the fee, the cost of rolling the futures from one month to the next, what the futures traded at against Bitcoin, and what the market paid for the shares, all of it together. It is the only number on this page the sponsor does not publish itself.
