NYSE Arca and NYSE American have successfully filed rule changes with the U.S. Securities and Exchange Commission, eliminating the previous 25,000 contract limit on spot Bitcoin and Ethereum ETF options. This change aligns these options with the framework applied to other commodity ETF options. The position limits will now be dynamically adjusted based on trading volume and circulation scale, with some high-liquidity products potentially increasing to over 250,000 contracts. Additionally, the exchanges will now permit the trading of FLEX options.
