Kalshi Implements Job Disclosure to Prevent Insider Trading
Kalshi, a prediction market platform, announced that certain users will soon be required to disclose their employment details when placing specific bets. This measure aims to curb insider trading on the platform.
The platform, which allows users to wager against each other on outcomes such as elections, sports events, and cultural happenings, stated on Tuesday that it will begin collecting work information from users attempting to place bets that might benefit from insider knowledge.
Kalshi indicated that this policy will apply to "markets with heightened insider or manipulation risk." As an example, it cited a potential trade on which company, OpenAI or Anthropic, will go public first.
Rising Concerns Over Insider Trading in Prediction Markets
Prediction markets have faced increasing scrutiny over insider trading as their popularity grows. Notably, former Congressman George Santos is under investigation for alleged insider trading on Kalshi, according to NPR.
Earlier this year, Kalshi revealed that candidates for Congress from Minnesota, Texas, and Virginia were placing bets on their own races.
In the first quarter of this year, Kalshi reported making more than 20 referrals to law enforcement regarding potentially illegal trading activities after conducting over 150 internal investigations.
Last month, a Google employee was charged with insider trading for using confidential company information to place bets on Polymarket, a competing prediction market platform.
Additionally, earlier this year, a US special forces soldier was accused of making successful bets on Kalshi related to the operation to remove Venezuelan President Nicolás Maduro. The soldier has pleaded not guilty.
New Measures to Identify and Prevent Insider Trading
By requiring users to provide employment information, Kalshi aims to "identify presumptive insiders… and screen them out before a trade is ever placed."
The company has also developed a new risk scoring system designed to detect betting markets that are more vulnerable to manipulation or insider trading. This includes markets related to specific companies and matters of national security.
