Polymarket Traders Net Roughly $1 Million on US‑Iran Strike Forecasts, Prompting Insider‑Trading Scrutiny
By Cointelegraph Staff • March 1 2026
Summary
Six newly created Polymarket wallets amassed close to a million dollars after correctly predicting that the United States would launch a strike against Iran before the end of February. The timing of the purchases—often only a few hours before the first reports of explosions in Tehran—has triggered concerns that the traders may have accessed non‑public information. The episode adds to a growing list of alleged insider‑trading incidents on the decentralized prediction‑market platform and comes as U.S. lawmakers prepare legislation aimed at curbing such activity.
What happened
- Profit from a timely bet: Six anonymous wallets, all opened in February, placed the majority of their activity on Polymarket contracts that asked whether the United States would strike Iran by the end of the month. The combined profit from these positions is estimated at roughly $1 million.
- Speed of the trades: In several instances, the contracts were purchased mere hours before the first media reports of explosions in Tehran. Some of the positions were acquired for as little as $0.10 per share.
- Volume context: During the recent geopolitical escalation, more than $529 million flowed into Iran‑related contracts on Polymarket. The contract tied to a February 28 strike date alone attracted about $90 million in trading, making it the most heavily traded scenario, while a January 31 date saw roughly $42 million in activity.
The data supporting these observations come from blockchain analytics firm Bubblemaps SA, which shared transaction details with Bloomberg and Cointelegraph. Bubblemaps’ chief executive, Nicolas Vaiman, noted that information surrounding conflicts can circulate within close‑knit circles before it becomes publicly available, and the low‑friction, wallet‑only entry model of Polymarket may encourage participants with privileged knowledge to act early.
Why the pattern raises red flags
On‑chain investigators have flagged the behavior as reminiscent of prior cases where suspected insider trading was alleged on prediction‑market platforms. The key elements that set off alarms are:
- New wallets focused on a single event: All six wallets were created shortly before the strike‑related contracts appeared and directed most of their trading capital toward those specific outcomes.
- Near‑instantaneous timing: The purchases coincided closely with the first public reports of hostilities, suggesting the traders may have been acting on information not yet disseminated widely.
- Low‑cost entry with high upside: Acquiring contracts at pennies per share and later realizing six‑figure gains aligns with a risk‑reward profile typical of insider‑information exploitation.
While one of the flagged wallets had previously lost money on an earlier, unrelated prediction before posting the winning wager, the overall pattern does not constitute definitive proof of wrongdoing. However, it adds to a series of incidents that have drawn regulatory and public attention.
Recent history of similar allegations
- Axiom investigation bet: Earlier this week, a small group of wallets earned more than $1.2 million by wagering on a contract linked to a forthcoming on‑chain investigation of the DeFi platform Axiom. The timing of the trades preceded the release of the investigation’s findings by just a few days.
- Maduro removal wager: In February, a Polymarket participant secured roughly $400 000 by betting on the removal of Venezuelan President Nicolás Maduro. The position was entered shortly before the news became public, prompting another wave of insider‑trading concerns.
These cases illustrate a recurring theme: substantial profits realized by traders who appear to act on information before it is broadly reported.
Legislative response
U.S. Representative Ritchie Torres is drafting the Public Integrity in Financial Prediction Markets Act of 2026. The proposal would prohibit elected officials, political appointees, and other federal employees from trading prediction‑market contracts that relate to government policy or political outcomes when they possess non‑public information. If enacted, the bill would create a regulatory framework specifically targeting insider activity in decentralized prediction markets such as Polymarket.
Global regulatory pressure on Polymarket
Polymarket’s operations have already encountered scrutiny in multiple jurisdictions. Several European nations—including the Netherlands, Hungary, Belgium, France, Italy, Romania, Poland, Singapore, and Portugal—have either blocked or banned the platform, arguing that its event‑based contracts constitute unlicensed online gambling rather than legitimate financial instruments. The mounting regulatory actions underscore the broader challenges the platform faces in aligning its decentralized model with traditional securities and gambling laws.
Analysis
The February‑Iran strike episode highlights several structural vulnerabilities in prediction‑market ecosystems:
- Anonymity and low entry barriers make it feasible for individuals with insider knowledge to conceal their identity while executing high‑impact trades.
- Rapid market formation around geopolitical events provides a fertile ground for opportunistic behavior, especially when public signals (e.g., official statements, diplomatic warnings) are ambiguous or lag behind internal deliberations.
- Limited oversight of decentralized platforms means that traditional enforcement mechanisms—such as SEC investigations—are harder to apply, leaving on‑chain analytics and community watchdogs as the primary means of detection.
If insider‑trading activity continues unchecked, it could erode confidence in prediction markets, limit participation from institutional players, and invite stricter regulatory measures that may fundamentally alter how such platforms operate.
Key takeaways
- Six Polymarket wallets earned about $1 million by correctly forecasting a U.S. strike on Iran before the end of February, with trades executed minutes or hours before the first news reports.
- The pattern of newly created wallets focusing solely on a single event, coupled with the timing of the purchases, has raised suspicions of insider trading.
- This incident adds to a series of high‑profit, time‑sensitive bets on Polymarket that have attracted similar scrutiny, including wagers on the Axiom investigation and the removal of Venezuelan President Maduro.
- U.S. lawmakers are moving to close a regulatory gap with proposed legislation that would bar government officials from trading on non‑public information in prediction markets.
- Polymarket continues to face regulatory actions worldwide, with several countries classifying its contracts as illegal gambling.
The episode underscores the tension between the open, decentralized nature of blockchain‑based prediction markets and the need for safeguards against the exploitation of privileged information. As regulators and the crypto community grapple with these issues, future market participants may see tighter compliance requirements and enhanced transparency measures.
