NYSE Arca and NYSE American have removed the 25,000-contract position and exercise limits on options tied to 11 spot Bitcoin and Ethereum ETFs, with immediate SEC effectiveness. The update covers products including BlackRock’s iShares Bitcoin Trust and Fidelity’s Wise Origin Bitcoin Fund, and also permits FLEX options trading for the affected crypto ETF options. Under the revised framework, position limits can rise above 250,000 contracts based on liquidity, further expanding trading flexibility for listed options on spot crypto ETFs. Separately, Nasdaq ISE is seeking approval for a 1 million-contract position limit for IBIT options, with public comments due by April 13.
