Prediction Market Surge Raises New Questions for Election Officials
Heavy trading on election prediction markets is raising concerns among US election officials about its impact on democracy and voter confidence.
Trading on prediction markets tied to major US elections is surging, prompting a fresh wave of concern among election administrators who fear the high-stakes financial activity could further erode public trust in democratic processes.
Platforms like Polymarket and Kalshi allow users to buy and sell contracts priced between one and 99 cents, reflecting the perceived probability of an event, from local mayoral races to control of Congress. The volume of such trading has skyrocketed this year, even as several states pursue legal action to classify the platforms as unlicensed gambling operations.
Jared DeMarinis, administrator of the Maryland State Board of Elections, called the trend troubling for election officials nationwide. The core worry, he and others say, is that pervasive financial incentives could make voters suspect that outcomes are being influenced by money rather than ballots.
Operators of the markets reject the comparison to gambling, arguing their platforms function like other financial exchanges. They note that trading allows investors to hedge against policy shifts and that their odds have historically been accurate. Kalshi also points to internal safeguards, including a recent case where a congressional candidate was suspended and fined for trading on her own race.
However, the markets have faced notable missteps this year, including favoring a losing candidate in a Wisconsin primary and sparking online accusations of manipulation during the Los Angeles mayoral race. These incidents have fueled debates about whether wealthy actors could artificially inflate a candidate's odds to create a bandwagon effect, potentially swaying public opinion or donor interest.
While some analysts acknowledge the theoretical risk of manipulation, they note that liquid markets often self-correct as traders move to profit from mispriced contracts. Still, the potential for abuse in smaller elections remains a concern for law enforcement.
With courts unlikely to settle the legality of these platforms before the upcoming elections, officials are preparing for unprecedented trading volumes. In the meantime, administrators are exploring measures like updating oaths for election workers to prohibit betting and planning public education campaigns to clarify that market odds are not the same as polls or official results.
