S&P 500 Futures and Options will be Delisted Following the September Roll with Open Interest Migrating to E-mini S&P 500 Contracts

CHICAGO, May 4, 2021 /PRNewswire/ -- CME Group, the world's leading and most diverse derivatives marketplace, today announced that it will not reopen its physical trading pits that were closed last March due to the outbreak of the COVID-19 pandemic. The Eurodollar options pit, which was reopened last August, will remain open, allowing these contracts to continue to trade in both open outcry and electronic venues.
CME Group also announced that, subject to regulatory review, it will delist its full-size, floor-based S&P 500 futures and options contracts following the expiration of the September 2021 contracts on September 17, 2021. Open interest that remains after the delisting will be migrated into the E-mini S&P 500 futures and options contracts that are available electronically on CME Globex. All individual trading positions will be converted into the corresponding E-mini S&P 500 contracts with the matching expiration date and strike price for options at the current 1:5 ratio.
