The U.S. Securities and Exchange Commission (SEC) approved stock exchange rule changes that permit the listing of options tied to spot bitcoin ETFs, broadening the investment ecosystem around products that've received billions of dollars of inflows this year.

According to two memos from the SEC published Friday afternoon, NYSE will be allowed to list and trade options on the Grayscale Bitcoin Trust (GBTC), the Grayscale Bitcoin Mini Trust (BTC) and the Bitwise Bitcoin ETF (BITB). Cboe Global Markets got approval to list and trade options on the Fidelity Wise Origin Bitcoin Fund (FBTC) and the ARK 21Shares Bitcoin ETF (ARKB).

The approval comes several weeks after the SEC approved Nasdaq's rule proposal to allow the listing and trading of options on BlackRock's iShares Bitcoin Trust (IBIT).
