Kalshi has suspended and fined three congressional candidates for “political insider trading” after they placed bets on their own election outcomes.Météo-France filed a police complaint following suspicious temperature spikes at Paris-Charles de Gaulle airport that netted a Polymarket trader over $20,000.The dual incidents highlight growing regulatory concerns regarding market manipulation and the physical security of data sources used to settle prediction contracts.

The rapidly expanding prediction market industry is facing a new wave of integrity challenges as platforms and state agencies move to curb insider trading and physical market manipulation. In the United States, the regulated exchange Kalshi announced the suspension of three political candidates who wagered on their own races, while in France, authorities are investigating allegations that a weather sensor was tampered with to influence payouts on Polymarket. Kalshi’s enforcement action targeted Mark Moran (Virginia), Matt Klein (Minnesota), and Ezekiel Enriquez (Texas). According to disciplinary filings, the candidates were flagged by the platform’s recently implemented technological guardrails designed to prevent politicians and athletes from trading on events they can influence. While the bets were relatively small—in some cases under $100—Kalshi imposed five-year suspensions and fines up to $6,200 to maintain market neutrality. “Regulated exchanges must constantly evolve and adapt their systems to address insider threats,” stated Robert DeNault, Kalshi’s head of enforcement. Simultaneously, Météo-France, the French national weather service, has alerted the Air Transport Gendarmerie regarding “anomalies” at its Paris-Charles de Gaulle airport station. On April 6 and April 15, sensors recorded localized temperature spikes of several degrees within minutes—movements that did not align with regional weather patterns. These spikes directly coincided with highly profitable bets on Polymarket’s “Highest temperature in Paris” contracts. In one instance, a trader turned a $119 stake into more than $21,000 after betting on a specific temperature rise just before the sensor anomaly occurred. Independent analysts and weather enthusiasts have speculated that the sensor may have been manipulated using a portable hairdryer or lighter. While Polymarket operates as an unregulated platform in many jurisdictions, the incident has raised alarms about the vulnerability of real-world data feeds (oracles) that these markets rely on for settlement. In response to the suspected foul play, Polymarket has reportedly shifted its data source for Paris weather to a different sensor at Le Bourget Airport. The convergence of these events arrives at a critical time for the industry, as lawmakers and the Commodity Futures Trading Commission (CFTC) weigh stricter oversight for event-based derivatives. Critics argue that the incentive for small-scale physical tampering or insider betting could undermine the broader utility of prediction markets as accurate forecasting tools. “Regardless of the size of a trade, political candidates who can influence a market based on whether they stay in or out of a race violate our rules,” said Robert DeNault, Kalshi’s head of enforcement.
