The CME Group has launched new financially-settled Micro E-mini S&P 500 and Nasdaq-100 options.
The key benefit is cash settlement at expiry – no futures assignment, no physical delivery mechanics to manage.

- The various weekly series (Monday–Thursday and Friday Weekly 1/2/4) will be permanently delisted progressively between 14 July and 14 August 2026, End-of-Month series by 30 September 2026, Friday Week 3 and the standard monthly Options will continue trading through their last listed contract month before permanent delisting on 18 December 2026. Hence, liquidity will progressively shift to the newer contracts.
