Cboe Global Markets is preparing to reintroduce "all or nothing" binary options contracts aimed at retail investors, targeting the expanding prediction market sector. These contracts will function as fixed-income derivatives, offering a fixed payout if specific conditions are met at expiration, otherwise becoming worthless. Cboe's previous attempt in 2008 to launch similar options linked to major indices was unsuccessful due to institutional market dominance. The exchange plans to ensure rigorous legal and compliance checks, with oversight by the U.S. Securities and Exchange Commission or the Commodity Futures Trading Commission.
