Prediction markets have moved from a curiosity to a mainstream venue for betting on politics, and the coming midterms are the first national election since that surge. The referrals land with a regulator that has so far left most of the work of catching improper trades to the platforms themselves.
Shana Bautista oversees two very different venues: a U.S.-regulated exchange where users must prove their identities, and a larger international platform where trading is anonymous and settled in crypto. Her surveillance system draws on social media, Federal Election Commission filings, banking and crypto partners and statistical models, and she told NPR that her team of 16 fields hundreds of alerts a day. None of this began with the election calendar. The company's integrity program has been running for some time, and the midterms are its most visible test to date. Well before the midterms, Bautista told Reuters in August, more than a hundred matters had gone to law enforcement, among them a wallet prosecutors have tied to a U.S. soldier's wager on the capture of Venezuela's Nicolas Maduro.
The regulatory backdrop is unsettled. Lawmakers have questioned whether wagering on elections belongs in regulated markets at all, and several states are challenging the industry in court. Earlier this year the CFTC's enforcement division said it holds full authority to prosecute illegal trading on registered exchanges, while those exchanges carry an independent duty to run surveillance and enforce their own rules, the division said in an advisory that followed two cases handled internally by rival Kalshi, one involving a candidate trading on his own race. Academics who study the markets warn that election contracts carry a special risk: a shift in perceived odds can itself change how voters and donors behave.
