What a spot ETF holds
An exchange-traded fund, or ETF, is a fund whose shares trade on a stock exchange like any company’s shares. A spot bitcoin ETF buys bitcoin and keeps it with a custodian, a specialist firm that holds the keys.
The fund issues shares, each worth a slice of the pile. You buy the shares through the broker you already use.

“Spot” means the fund holds the coin itself. An earlier kind of fund held futures contracts, agreements to buy or sell at a set price on a later date, which is a different thing with its own costs.
The US Securities and Exchange Commission (SEC) approved the first spot bitcoin ETFs on 10 January 2024. Gary Gensler, its chair at the time, said that day: “we did not approve or endorse bitcoin.” The SEC cleared the exchanges to list spot ether funds on 23 May 2024, and the first of them began trading on 23 July 2024.
