Polymarket Iran Deal Bets Raise Insider Trading Concerns
Claire Weston
What did this account do, and why is it suspicious?
Days before the US-Iran peace-deal news broke, one account bought heavily into "yes" contracts at a market-implied probability of just 6%. If all four linked markets settle its way, the payout is roughly $1.1 million, with a single position worth about $370,000.
The account was created two hours before its first trade and is tied to a single blockchain wallet. This means → it had no trading history — it was built for this bet and nothing else.
This is the latest in a string of "precision bets" during the Iran conflict, each placed on the eve of a major policy announcement, each yielding returns far above normal levels.
What happened in traditional markets?
The CFTC — the US federal agency that regulates futures — has opened a probe into potential insider trading in oil futures.
On March 23, between 6:49 and 6:51 a.m. New York time, contracts representing at least 7 million barrels of Brent and WTI crude changed hands. Volume spiked to more than 20 times the normal level for that time of day — roughly 15 minutes before Trump announced on Truth Social that he would pause strikes on Iranian energy infrastructure.
Within four minutes, oil dropped more than 14% and S&P 500 futures rose about 3%. In plain terms = someone executed a textbook "oil-down, equities-up" trade with minute-level precision, right before the news went public.
How are lawmakers and regulators responding?
Democratic lawmakers and other critics argue the timing of multiple bets is "nearly impossible to explain by skill or luck alone."
There is precedent: a US Army soldier was identified and charged after using classified information to bet on Polymarket that Venezuelan leader Maduro would be ousted, netting roughly $400,000.
The White House has warned staff against trading on classified information, and the Senate has banned members and aides from using prediction markets. This means → policy has moved past concern and into rule-setting.
Can blockchain reveal who did it?
Polymarket users trade through anonymous blockchain wallets, making it hard to pin down real-world identities — a fundamental difference from regulated futures exchanges.
Yet blockchain transactions are inherently public. Researchers can trace wallet behavior in finer detail than is possible in traditional markets. Data from analytics firm Polysights shows suspicious activity accelerated throughout the conflict.
In plain terms = the blockchain makes you anonymous but makes every move you take permanently auditable — it can't tell "who you are," but it can show "exactly what you did."
Is this market still growing?
Polymarket's geopolitics category is now one of the platform's fastest-growing segments, attracting roughly $5 billion in bets year-to-date.
April alone saw trading volume top $1.5 billion, an all-time record for the category.
This reflects a structural paradox: the bigger the market gets, the larger the potential profit for anyone holding non-public information — and as prediction markets bind ever more tightly to geopolitical events, that vulnerability will not close on its own.
