US lawmakers have opened a major investigation into prediction market platforms Polymarket and Kalshi following allegations that users may have profited from confidential government information tied to geopolitical and political events.
The probe is being led by the House Oversight Committee, chaired by James Comer, who is demanding internal records from both companies within two weeks.
Wichtige Erkenntnisse
- Congress is investigating Polymarket and Kalshi over possible insider trading activity.
- Lawmakers are concerned government employees may be using classified information to place bets.
- The probe follows cases tied to the Iran conflict and Nicolás Maduro-related markets.
- Both platforms say they already have systems in place to prevent insider trading.
Lawmakers Demand Internal Records
According to reports, Comer sent formal letters to Kalshi CEO Tarek Mansour and Polymarket CEO Shayne Coplan requesting documents related to insider trading prevention and user verification procedures.
The investigation focuses on whether traders may have used nonpublic government or military information to gain an unfair advantage in prediction markets tied to wars, elections, and international political events.
Comer reportedly warned that government insiders could potentially be making “huge profits” through access to confidential information.
Probe Linked to Maduro and Iran Cases
The investigation follows several high-profile incidents that raised concerns about suspicious trading activity on prediction market platforms.
Federal prosecutors in April charged US Army Special Forces soldier Gannon Ken Van Dyke with allegedly using classified government information to place bets related to the capture of former Venezuelan leader Nicolás Maduro.
Authorities claim the trades generated more than $400,000 in profits.
Meanwhile, a recent investigation highlighted by CBS News and “60 Minutes” reportedly found that several Polymarket accounts earned millions of dollars by accurately predicting major developments tied to the Iran conflict.
Prediction Markets Face Regulatory Scrutiny
Prediction markets allow users to speculate on the outcomes of future events, ranging from elections and sports to geopolitical developments.
The platforms have rapidly grown in popularity, but regulators and lawmakers are increasingly questioning whether existing rules are sufficient to prevent insider trading and market manipulation.
Das Commodity Futures Trading Commission currently oversees parts of the prediction market industry and formally prohibits insider trading. However, lawmakers argue that regulations may not fully address the risks posed by decentralized and crypto-linked trading systems.
Platforms Respond With New Safeguards
Both Polymarket and Kalshi say they already maintain market integrity systems designed to detect and prevent improper trading behavior.
Kalshi recently banned members of Congress from creating accounts after an internal investigation found several congressional candidates had traded on their own election outcomes. The company also suspended those accounts for five years.
Polymarket introduced a similar rule earlier this year prohibiting users from betting on events if they hold positions of authority or influence that could directly impact the outcome.

Fazit
The congressional investigation marks one of the most serious political and regulatory challenges yet for the fast-growing prediction market sector.
As platforms like Polymarket and Kalshi expand into politically sensitive and geopolitical betting markets, lawmakers are increasingly focused on whether insider information and government access could undermine market fairness and public trust.
The outcome of the probe could shape future legislation and determine how prediction markets operate in the United States moving forward.
