Cboe's trading floor has been at the center of market innovation since 1973, when the first U.S. listed options were traded in what was once the smoking lounge at the Chicago Board of Trade. Today, it is the world's largest options trading pit, blending the dynamic energy of open outcry trading with advanced digital and electronic technology following Cboe's return to the historic CBOT building in 2022. In 2026, Cboe will introduce a refreshed Customer Experience Center, creating a modern, media-ready space that brings visitors closer to the markets and Cboe's story.
Bell Ringings at Cboe are a signature tradition that celebrate key milestones, new listings, corporate achievements and community moments from the heart of the trading floor. Each event brings issuers, partners, and guests into the energy of the marketplace, supported by coordinated photography, videography and a dedicated run of show to ensure a memorable experience. As part of Cboe's expanding media presence, Bell Ringings will now take place twice daily — an Opening Bell in the morning and a Closing Bell in the afternoon — both of which will receive dedicated broadcast coverage as part of the growing Cboe + CNBC partnership.
