CME Group says it will close most of its futures trading pits in Chicago and New York City by July 2, 2015.
It will maintain its options trading pit and the S&P 500 futures market.
"Equity index futures pits and the DJIA ($10) and NASDAQ-100 options pits will close following the expiration of the June 2015 contract on June 19, 2015," the company said in a release.
CME Group says it will try to offer booth space to those who want to trade electronically following the closures.
