University of Chicago students protested outside the Chicago Mercantile Exchange, wearing onion costumes and demanding the repeal of the 1958 Onion Futures Act. Kalshi, the $40 billion prediction market platform, funded the protest through its co-founder Tarek Mansour, a vocal critic of the law. The demonstration highlights Kalshi's interest in expanding its trading capabilities beyond the current restrictions.
While the protest focused on onions, industry experts suggest the real financial opportunity lies in a 2010 amendment banning movie box office futures. Finance professor Craig Pirrong noted that if the law were repealed, Kalshi could access a much larger market for box-office derivatives than onion trades. Agricultural economist Scott H.
Irwin views Kalshi's stance as a matter of principle, arguing the company believes it should be able to trade anything. Regardless of the specific commodity, the debate underscores the broader tension between prediction market platforms and legacy commodity regulations. The Onion Futures Act was originally enacted to prevent market manipulation by Sam Siegel and Vincent Kosuga, who once controlled 98 percent of Chicago's onion supply to rig prices.
Futures contracts generally help farmers manage financial risks associated with harvesting and shipping commodities, but onion futures remain the only agricultural commodity banned under federal law due to this historic scheme.
