An anonymous reader quotes a report from Ars Technica: Several US senators have written a letter to the Commodity Futures Trading Commission (CFTC), inquiring about the agency's "plans to crack down on prediction markets" that offer "contracts for individuals to bet on wildfires." "Offering bets on destructive wildfires threatens to minimize communities' suffering, all so the rich and powerful can profit," wrote (PDF) the group of senators, who represent Oregon, California, Nevada, Minnesota, and New Hampshire. The document specifically cites that Polymarket hosted bets in January 2025 on the wildfires in Los Angeles, and it mentions another website which specifically accepts "simulated bets" exclusively on California wildfires. "There's also the heightened risk -- according to state and local fire officials -- that individuals could be tempted to commit arson in order to make sure their bets are successful," the letter continues. "By offering contracts on fires, prediction market sites run the risk of encouraging people to influence fires that have already started, creating additional concerns around public safety and insider trading." [...] Kalshi spokesperson Elisabeth Diana told Ars by email that the company does not allow such wildfire markets "because they create perverse incentives." But its primary rival, Polymarket, has taken a different approach. A spokesperson for Polymarket told Ars in an emailed statement that the company does not "profit from outcomes," adding that people "come to Polymarket for information." "While we are not blind to the risks, removing these markets does not prevent a tragedy but makes the most accurate information less accessible to the people who need it most," he wrote.
