The CME Group has introduced event contracts with quarter- and year-end expiries for E-mini S&P 500 and E-mini Nasdaq-100 futures on January 29. These extended-duration contracts aim to offer market participants an additional distinctive avenue to articulate their perspectives on the trajectory of these equity indices. Along with the expanded expiries, the following event contract product specification changes will be made.

• The contract size of all event contracts will change from a maximum of $20 to a maximum of $100 before fees.
• The price range of all event contracts will change from a range fluctuation between 0-20, in 0.25 increments, to a range fluctuation between 0-100, in 1.00 increments.
• The array of expirations tied to E-mini S&P 500 and E-mini Nasdaq-100 futures contracts will be expanded to include additional “quarter-end” and “year-end” expiries.
• This expiry expansion will require an expanded strike array to accommodate additional potential outcomes over a longer time period.
• These new expiries will carry open interest over time, and thus will require daily settlement and overnight margining of event contracts for the first time.
