On October 2, 2026, the Securities and Exchange Commission published notice of a rule change that lets Investors Exchange list options on commodity-based trusts holding Bitcoin and other crypto assets, and that sets position and exercise limits for options on BlackRock’s iShares Bitcoin Trust ETF. The filing, Release No. 34-106575, arrived the same day IEX’s new options venue, IEX Options, was scheduled to begin trading, and the Commission made it effective immediately.
