Betting on a potential Iran war has exploded on Polymarket, pushing the platform's geopolitics category to new heights. But the surge is drawing unwanted attention from lawmakers in Washington, who are looking at stricter rules for prediction markets.
Why the geopolitics category is booming
The increase in wagers on an Iran conflict comes amid rising tensions in the Middle East. Polymarket users have poured money into contracts like “Iran-Israel war in 2025” and “Iran nuclear deal collapses this year.” The platform doesn't break out exact dollar amounts by subcategory, but company data shows the geopolitics vertical has more than doubled in trading volume over the past month.
Polymarket's structure lets anyone bet on real-world events using cryptocurrency. That's made it a go-to for traders who want to hedge or speculate on geopolitical outcomes. The Iran bets are particularly active — some contracts have seen six-figure sums change hands in a single day.
Congress takes a closer look
The spike hasn't gone unnoticed on Capitol Hill. Several committees have started examining whether Polymarket and similar platforms violate existing commodities or gambling laws. A bipartisan group of senators recently sent a letter to the Commodity Futures Trading Commission asking for an update on enforcement actions against unregistered prediction markets.
“We're concerned that these markets are operating without oversight, especially when they involve conflicts that could affect national security,” the letter stated. “The public deserves to know who is behind these bets and whether foreign actors are using them to manipulate sentiment.”
The CFTC has already taken enforcement steps against Polymarket in the past. In 2022, the agency fined the company $1.4 million for offering illegal binary options contracts. Polymarket agreed to settle and later restructured its offerings to focus on event contracts it argues are not subject to CFTC jurisdiction.
What stricter rules could look like
Legislators are considering several options. One bill would classify any prediction market with contracts tied to U.S. elections or military actions as a “swap” under the Commodity Exchange Act, which would require registration and reporting. Another proposal would give the CFTC clear authority to block contracts that involve “war, terrorism, or armed conflict.”
Industry groups are pushing back. They argue prediction markets provide valuable forecasting data — sometimes more accurate than polls or intelligence assessments. “If you regulate these markets out of existence, you lose a cheap, real-time signal about what people think is likely to happen,” said one trade association representative in a recent hearing. Polymarket itself has declined to comment on the regulatory discussions.
What happens next
The CFTC is expected to issue a proposed rule on event contracts by the end of the quarter. That rule could directly affect Polymarket's Iran war bets and many other geopolitical listings. Separately, a House subcommittee has scheduled a hearing for next month titled “Prediction Markets: Forecasting or Gambling?” Polymarket has not been invited to testify, according to committee staff.
For now, the Iran contracts keep trading. The question is how long they'll stay open.
