U.S. Congress Investigates Insider Trading on Prediction Markets
James Comer, Chairman of the U.S. House Committee on Oversight and Government Reform, announced an investigation into insider trading on prediction market platforms Kalshi and Polymarket, and has sent letters to the CEOs of both companies requesting relevant documents.
The investigation focuses on identity verification, geographic restrictions, monitoring of unusual trading, and how the platforms prevent trading based on insider information. Comer has requested that both companies submit information by June 5.
Previously, a U.S. soldier profited $400,000 from insider information regarding the political situation in Venezuela, and over 80 users on Polymarket placed unusual bets before the U.S. attacked Iran, raising regulatory concerns.
Institutional traders and insiders tend to bet on high-certainty outcomes driven by events, benefiting from the platforms' fee structures, while ordinary retail investors face pressure from information asymmetry, leading to capital flowing towards specialized accounts.

James Comer, as a senior Republican congressman, has previously led multiple investigations into the Biden family's business dealings. His shift to investigating prediction markets reflects his ongoing concern about potential abuses of power and trading on non-public information. He has also previously advocated for legislation related to government transparency.
In terms of capital flow, the investigation aims to bring the platforms back under federal oversight by mandating the disclosure of user records, thereby enhancing KYC and monitoring system investments. The motivation is to prevent government employees or congress members from profiting from insider information, thus protecting the credibility of prediction markets as information aggregation tools rather than speculative instruments.
Similar to the attention Polymarket received during the 2024 U.S. election due to high trading volumes and accuracy, this investigation places prediction markets at a critical juncture from marginal innovation to mainstream financial infrastructure. Kalshi, as a CFTC-regulated platform, is facing stricter compliance pressures.
Essentially, this represents a restructuring of the industry driven by regulatory changes. Congress's investigation strengthens control over pricing power in non-traditional financial platforms, extending the definition of insider trading from stocks to event predictions, forcing platforms to shift from "decentralized freedom" to "controlled transparency" to avoid market distortions caused by groups with information advantages extracting liquidity from retail investors.

The more concealed the information asymmetry, the more intense the regulatory pursuit.
A free market may flourish first, but it will inevitably face the iron hammer of rules.
Those who predict the future, if relying on insider information rather than insight, will first be nailed to the pillar of shame.
