Following intense criticism, Polymarket has taken down a market that allowed users to bet on the rescue of US service members in Iran. The market, which was deemed to have fallen short of the company's integrity standards, had sparked outrage among lawmakers, with Rep. Seth Moulton condemning it as 'disgusting' for reducing a military rescue effort to a financial transaction.

The incident has highlighted the growing regulatory scrutiny of prediction markets, with congressional Democrats pushing for legislation to prohibit contracts tied to sensitive events. The Commodity Futures Trading Commission has also filed lawsuits against states attempting to bypass federal oversight, while industry players like the NFL are urging operators to avoid offering objectionable contracts. Despite the challenges, the market continues to evolve, with new entrants like JPMorgan and Kalshi expanding their offerings, including margin trading for institutional investors.
