Prediction markets scrutiny
U.S. prediction‑market platforms are facing intensified regulatory and law‑enforcement scrutiny after high‑profile war and politics bets drew criticism from Washington. The AP flagged Congressional attention to platforms like Kalshi and Polymarket, OPB reported arrests in Israel tied to alleged trading on classified information, and Bloomberg noted Wall Street quants are still mining these markets for earnings signals.

Prediction markets are drawing new scrutiny from Congress, regulators and police as bets on war, pardons and elections move closer to the political mainstream. (apnews.com) These sites let users buy contracts tied to a future outcome, usually for yes-or-no questions that pay a fixed amount if the event happens. The Commodity Futures Trading Commission says these products are called event contracts and have traded on regulated U.S. markets for more than two decades. (cftc.gov) In the United States, Kalshi operates as a Commodity Futures Trading Commission-regulated exchange, while Polymarket has remained off-limits to many U.S. users after a 2022 settlement and says it restricts access in barred jurisdictions. Polymarket’s help center says the platform prohibits the use of virtual private networks to get around those blocks. (kalshi.com) (help.polymarket.com) The pressure rose after high-profile markets on Iran and U.S. politics prompted complaints in Washington. The Associated Press reported this week that members of Congress are pressing for tighter oversight of platforms including Kalshi and Polymarket after those bets drew criticism. (apnews.com) The Commodity Futures Trading Commission also opened a formal rulemaking step on March 12, 2026, asking for public comment on whether to amend or add rules for prediction markets. The Federal Register notice says the agency is seeking input on which event contracts may be barred as contrary to the public interest. (cftc.gov) (federalregister.gov) Enforcement worries are no longer theoretical. On February 25, 2026, the Commodity Futures Trading Commission’s enforcement division issued an advisory after two public cases involving misuse of nonpublic information and fraud in prediction markets traded on Kalshi. (cftc.gov) New reporting has added examples. OPB, citing NPR reporting and Bubblemaps analysis, said an anonymous Polymarket trader made about $316,346 on bets tied to former President Joe Biden’s final pardons, including wagers on Jim Biden, Liz Cheney, Adam Schiff and Adam Kinzinger. (opb.org) That report also cited Columbia Law School professor Joshua Mitts, who said the odds of those trades happening by chance were “virtually zero.” OPB said Polymarket did not return NPR’s request for comment. (opb.org) At the same time, Wall Street is treating some of these markets as useful data rather than noise. Bloomberg reported April 16 that Wolfe Research found Polymarket users called earnings misses 44% of the time when they bet a company would miss estimates, versus a historic benchmark of 18%, and correctly signaled earnings beats 90% of the time when confidence was high, versus an 81% norm. (bloomberg.com) The legal fight over who controls the business is still running alongside the ethics fight over what should be listed at all. In an October 2, 2024 opinion, the U.S. Court of Appeals for the District of Columbia Circuit described Kalshi’s congressional-control contracts as election bets the Commodity Futures Trading Commission had tried to block as gaming or gambling. (media.cadc.uscourts.gov) For now, prediction markets sit in two lanes at once: a regulated derivatives product on one side and a fast-moving venue for politically sensitive wagers on the other. The next clues are likely to come from Congress, the Commodity Futures Trading Commission’s rulemaking docket and whatever investigators find in the trades already under review.
