$70K Bet on US–Iran Ceasefire Sparks Insider Trading Fears on Polymarket

Eight newly created accounts on the crypto prediction platform Polymarket have wagered nearly $70,000 on a US–Iran ceasefire occurring before 31 March.

The sudden burst of activity has triggered widespread fears of insider trading within Washington or Tehran. These accounts appeared on 21 March and stand to collect a combined payout of $820,000 if the prediction holds. The timing is particularly suspicious as the bets were placed just before President Donald Trump publicly hinted at a military wind-down on Truth Social.

A Sudden Wave of Confident Bets

Experts first noticed the activity late last week. All eight accounts had been created around 21 March. They immediately began buying positions predicting a ceasefire between Washington and Tehran. The timing was striking. It came at a moment when political signals from the White House appeared to shift. President Donald Trump had initially adopted a hard line on the conflict. Soon afterwards, however, he hinted in a social media post that military operations might begin winding down.

That shift coincided with the burst of betting activity. Within days, Polymarket's estimated probability of a ceasefire before 31 March jumped from 6 per cent to 24 per cent. More than $21 million is now riding on that outcome across the platform.

Signs That Caught Attention of Analysts

Some market watchers believe the pattern of bets looks unusual. Ben Yorke, a former researcher at CoinTelegraph who now builds an artificial intelligence trading platform called Starchild, examined the activity. He suggested the wallets showed signs of someone with at least some degree of insider knowledge.

One reason is the structure of the bets. Instead of one large wager, the money appeared to be split across several accounts. This practice, often called wallet splitting, can obscure the identity of a single large trader. Analysts say such tactics are common when investors want to hide the size of their position. But it can also be a signal that someone is attempting to conceal sensitive information. According to Yorke, when traders deliberately obscure their identity, it often points to one of two possibilities. A very large investor seeking to protect market influence, or someone trading on information not available to the public.

A Suspicious History

The new bets also drew attention for another reason. One account placing a similar wager had appeared shortly before the US carried out strikes on Iran on 28 February. That account correctly predicted the attack.

It has placed no other bets on the platform. The pattern has deepened suspicions among crypto observers who monitor prediction markets for unusual activity. Still, proving insider trading in such spaces is extremely difficult. Polymarket accounts are anonymous. The crypto wallets behind them rarely reveal their owners.

The Rise Of Prediction Markets In Global Conflicts

Platforms such as Polymarket and Kalshi have rapidly become a new frontier in the information economy. These sites allow users to wager on real-world events ranging from elections to geopolitical developments. Supporters argue that markets can sometimes predict outcomes more accurately than traditional analysis.

Critics see a darker side. Some analysts worry that prediction markets could allow people with access to sensitive information to profit quietly from global crises. In recent months, certain bets have appeared to anticipate military actions involving the US, Israel and Iran.

Polymarket itself has already faced scrutiny from regulators and critics who question whether such platforms could encourage war profiteering. The company describes its system as a form of News 2.0. The idea is that markets reveal collective insight faster than traditional reporting. Yet sceptics argue that anonymous betting can also amplify rumours, misinformation and speculation.

A Bet That May Still Fail

Even if the traders possess inside information, their wager is far from guaranteed to succeed. Polymarket's rules require clear public confirmation from both the US and Iranian governments that they have agreed to halt military hostilities.

Without statements from both sides, the market will not settle in favour of a ceasefire. For now, the bets remain unresolved. Behind the numbers lies a broader question about the intersection of finance, technology and geopolitics. In a world where wars, diplomacy and digital markets collide in real time, information itself has become a valuable currency. Whether these traders were simply lucky or quietly informed may only become clear at month's end.
