Well-Timed Polymarket Bets on US-Iran Ceasefire Draw Scrutiny and Calls for Investigation

Lead

In the hours before President Donald Trump announced a two-week ceasefire between the US and Iran on Tuesday, a group of newly created accounts on the prediction market Polymarket placed highly specific bets that the two nations would reach a truce — wagers that netted hundreds of thousands of dollars in profits. The timing and precision of the trades have raised concerns about potential insider trading, prompting calls from lawmakers for investigations.

Coverage Comparison

According to multiple reports, the White House sent a staff-wide email on March 24 warning employees not to use insider knowledge to place bets on prediction platforms like Polymarket. The Wall Street Journal first reported the email, which came a day after Trump announced a five-day pause on his threat to attack Iranian power plants and energy infrastructure. White House spokesman Davis Ingle told the BBC that "any implication that Administration officials are engaged in such activity without evidence is baseless and irresponsible reporting," adding that federal employees are bound by ethics guidelines prohibiting the use of insider information for financial gain.

The Guardian reported that an analysis of publicly available blockchain data from Polymarket, using crypto analytics platform Dune, shows at least 50 accounts or wallets placed substantial "yes" bets on the ceasefire before Trump's announcement at approximately 6:30 pm ET. These were the first bets made by those wallets. One wallet, created on Tuesday at about 10 am ET, placed roughly $72,000 in bets at an average price of 8.8 cents and cashed out for a profit of $200,000. Another account that joined the platform on April 6 earned $125,500, while a wallet created just 12 minutes before Trump's post made $31,908 of bets at 33.7 cents and profited an estimated $48,500.

Key Claims

• A White House email on March 24 warned staff against using insider information to place bets on prediction markets, as reported by the Wall Street Journal and cited by the BBC and Jerusalem Post.
• New accounts on Polymarket made highly specific, well-timed bets on a US-Iran ceasefire before the announcement, leading to substantial profits, according to The Guardian's analysis of blockchain data.
• At least 50 accounts or wallets placed substantial bets on the ceasefire, per The Guardian's reporting, though this claim has not been corroborated by other sources in the reviewed coverage.
• One wallet placed $72,000 in bets and earned a $200,000 profit, according to The Guardian — a figure that has appeared in a single outlet's reporting.
• Congressman Richie Torres sent a letter to the Commodity Futures Trading Commission (CFTC) calling for an investigation, as reported by the Jerusalem Post and The Guardian.
• Senator Richard Blumenthal sent a letter to Polymarket demanding an explanation, per the Jerusalem Post.
• Polymarket stopped accepting wagers on the rescue of US warplane crew members after criticism from Congressman Seth Moulton, as reported by The Guardian. Moulton called the bets "DISGUSTING" on X.
• Polymarket came under scrutiny after a gambler made nearly half a million dollars betting on the capture of Venezuelan President Nicolás Maduro in January, according to the BBC.

Perspectives

Lawmakers and critics argue that the pattern of well-timed bets on geopolitical events suggests that traders may have had access to non-public information, and they are calling for regulatory oversight. Congressman Torres, in his letter to the CFTC, said: "This pattern raises serious concerns that certain market participants may have had access to material nonpublic information regarding a market-moving geopolitical event. The use of newly created wallets, combined with the precision and timing of these trades, raises serious red flags." Senator Blumenthal demanded an explanation from Polymarket about why it allows trades on war and violence.

Polymarket, the world's largest decentralized prediction market, has defended its operations, but it took down a market on the rescue of downed US pilots after Moulton's criticism, saying it "does not meet our integrity standards." The company said it was investigating how that market slipped through internal safeguards. Moulton, however, argued that the platform's "integrity standards are severely lacking," noting that Donald Trump Jr. is an investor in Polymarket.

Some analysts point out that the trades could have been speculative gambles based on Trump's pattern of making bold threats then backing down — a phenomenon critics have called "Trump always chickens out." The Guardian noted this possibility, but the timing and size of the bets have nonetheless drawn scrutiny.

The White House has denied that any administration officials engaged in such activity, calling the allegations "baseless and irresponsible reporting." Still, the episode has intensified calls from experts for regulation of prediction markets, citing concerns over insider trading and market abuse.

As the story develops, it remains to be seen whether the CFTC or other authorities will launch formal investigations, and whether Polymarket will take further steps to address the concerns raised by lawmakers and the public.
