In the volatile intersection of geopolitical tension and decentralized finance, a series of remarkably well-timed Polymarket bets on a U.S.-Iran ceasefire have sparked renewed scrutiny over the potential for insider trading within prediction markets. While the world watched a dramatic escalation in rhetoric from the White House, a small group of newly created accounts were placing high-stakes wagers that a diplomatic resolution was imminent.
The trades occurred on Tuesday, during a window of extreme uncertainty. Hours before a two-week ceasefire was announced, President Donald Trump had intensified his warnings on social media, stating that “a whole civilization will die tonight” if Iran failed to meet his demand to open the Strait of Hormuz by an 8 p.m. ET deadline. Despite these signals of imminent conflict, blockchain data reveals a cluster of traders who bet heavily on peace.
An analysis of public blockchain records via the crypto analytics platform Dune shows that at least 50 wallets placed substantial “yes” bets on the ceasefire before the President announced the deal in a Truth Social post at approximately 6:30 p.m. ET. Crucially, for many of these accounts, these were the very first trades they had ever executed on the platform.
The anatomy of a high-stakes win
The precision of the timing has drawn attention from market analysts. One wallet, established at roughly 10 a.m. ET on Tuesday, wagered approximately $72,000 at an average price of 8.8¢ per share. Because Polymarket contracts trade between $0 and $1—representing a 0% to 100% perceived probability—the low entry price indicates the trader was betting on an outcome the broader market considered highly unlikely. That user eventually cashed out with a profit of $200,000.
Other accounts showed similar patterns of opportunistic timing. One wallet joined the platform on April 6 and secured a win of $125,500 on the same event. Perhaps most striking was a wallet created just 12 minutes before the ceasefire announcement; this user placed $31,908 in “yes” bets at 33.7¢, resulting in an estimated profit of $48,500.
The increase in the “yes” price toward the end of the day may have been influenced by diplomatic efforts from the government of Pakistan, which was reportedly attempting to persuade the administration to extend the deadline by two weeks. Alternatively, some observers suggest the traders were betting on a known pattern of behavior, noting that critics of the President often point to a tendency to make bold threats only to retreat—a phenomenon some have labeled as “Taco,” or the idea that “Trump always chickens out.”
| Wallet Creation | Investment | Entry Price | Estimated Profit/Win |
|---|---|---|---|
| Tuesday, 10 a.m. ET | $72,000 | 8.8¢ | $200,000 |
| April 6 | Not specified | Not specified | $125,500 |
| 12 mins before post | $31,908 | 33.7¢ | $48,500 |
A recurring pattern of ‘predictive’ profits
This episode is not an isolated incident. The pattern of new accounts appearing just before major geopolitical shifts has happened before on Polymarket. In January, similar clusters of newly created wallets placed large wagers hours before the capture of Venezuelan President Nicolás Maduro, netting hundreds of thousands of dollars in profit. The platform has also seen repeated instances of well-timed bets regarding military actions involving Iran.
The anonymity of the blockchain complicates the investigation into these trades. Polymarket utilizes proxy smart contract wallets, which allow a single individual to operate multiple accounts. Public data cannot confirm whether these 50 wallets represent 50 different people or a single entity distributing their capital across multiple accounts to avoid detection. Only Polymarket possesses the internal data necessary to identify the users, and the company did not respond to requests for comment.
The push for prediction market regulation
The frequency of these “miracle” bets has moved the conversation from the trading floor to the halls of Congress. Bipartisan groups of senators and representatives have introduced legislation aimed at broadening the legal definition of insider trading to specifically include prediction markets. The goal is to prevent individuals with non-public, government-level information from leveraging that knowledge for private gain.
Industry leaders have acknowledged the require for a clearer framework. Both Kalshi and Polymarket have indicated that a broader definition of insider trading on their platforms may be necessary to maintain market integrity.
“This is why these markets need regulation,” said Todd Phillips, a professor at Georgia State University who specializes in prediction markets. “We can’t have people trading with inside information and expect other traders are going to be OK being in these markets.”
Payouts and pending disputes
Despite the announcement of the ceasefire, not all winning traders have received their funds. Polymarket has labeled the Iran-US ceasefire contract as “disputed.” The platform cited the fact that Iran continued to place restrictions on ships passing through the Strait of Hormuz and that missile attacks in the region persisted despite the diplomatic agreement.
This dispute process typically takes up to 48 hours to resolve, as the platform determines whether the conditions of the contract were strictly met. Until then, those who bet on the “yes” outcome remain in a holding pattern, waiting to see if the technicalities of the ceasefire outweigh the continuing hostilities on the ground.

The next critical checkpoint for these traders will be the resolution of the “disputed” status of the ceasefire contract, expected within the next two days. Simultaneously, the legislative efforts in Congress to regulate prediction markets continue to move through committee reviews.
