Several Polymarket traders have made outsized profits on US-Iran ceasefire bets, with one user reportedly seeing a roughly 3,500% gain.
The gains follow a de-escalation in US-Iran tensions that triggered rallies across equities, precious metals, and crypto. Onchain analysts and market watchers are now questioning whether the precision of these wagers points to something beyond luck.
Polymarket US-Iran Ceasefire Profits Spark Insider Trading Debate
Blockchain analytics firm Lookonchain flagged trader BlueHorseshoe86, who reportedly netted $194,000 betting on a US-Iran ceasefire. That profit added to a previous $260,000 gain from a “Maduro out” bet tied to the January capture of Venezuelan President Nicolás Maduro.
“His total profit now stands at $440K, all from bets on “Maduro out” and the US–Iran ceasefire,” Lookonchain added.
A separate trader turned $13,200 into $477,544, a gain of approximately 3,500%.
“He legit traded all the money he had in his account in this one. What did he know?” a market watcher questioned.

A third wallet, flagged as “suspicious” by prediction market tracker Polymarket History, reportedly earned more than $400,000 by correctly calling both the timing of the Iran military operation and the subsequent ceasefire.
“Created just before the operation. Two perfect calls. Over $400K in profit,” the post read.
While there is no confirmed evidence of insider trading, the outsized, well-timed gains have renewed concerns over insider trading on prediction markets. This is not an isolated incident, but part of a deepening pattern of suspected insider activity on these platforms.
The pattern of suspicious profits has prompted responses from both prediction market operators and US legislators. The lawmakers have introduced bills that would expand oversight and crack down on policymakers or government officials placing wagers.
Polymarket itself published updated market integrity rules. The new framework explicitly prohibits trading on stolen confidential information, acting on illegal tips, and placing wagers on outcomes a user can influence.
