Cboe Global Markets, Inc.
One of the world's largest derivatives and securities exchanges, Cboe Global Markets runs the trading venues behind famous products like SPX options, the VIX "fear gauge" index, and Bitcoin futures. Born in 1973 as the Chicago Board Options Exchange—the first U.S. exchange for standardized options—it was founded by the Chicago Board of Trade. Fun fact: its ticker is pronounced "see-bow," and its VIX index, launched in 1993, became Wall Street's go-to gauge of investor anxiety.
