Following severe 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 tied to the rescue of two airmen after an F-15E fighter jet was shot down over Iran, sparked outrage among lawmakers, with Rep.

Seth Moulton calling it 'disgusting' and arguing that it turned a military rescue effort into a financial transaction. Moulton has been a vocal critic of prediction markets, having recently banned his staff from using platforms like Polymarket and Kalshi due to concerns that financial incentives could influence policy decisions.

A spokesperson for Polymarket stated that the listing did not meet the company's integrity standards and was removed shortly after it appeared, with the company reviewing how the market passed internal safeguards. This incident comes as prediction markets face increasing pressure in Washington, with a group of congressional Democrats introducing legislation to ban contracts related to elections, war, and government actions. Additionally, several senators have urged the Commodity Futures Trading Commission to prohibit markets linked to individual deaths, citing national security concerns.

Regulators are also asserting their authority over the sector, with the CFTC filing lawsuits against three states over efforts to bypass federal oversight of prediction markets. The industry scrutiny has expanded beyond politics, with the NFL asking operators to avoid offering contracts that could be deemed objectionable or open to manipulation.

Despite the challenges, the market is expanding, with Kalshi securing a license to offer margin trading to institutional investors and new players entering the market, including JPMorgan, whose CEO has signaled the company's intention to enter the market.
