Prediction market operator Kalshi introduces a new procedure designed to identify potential insiders before they make trades. The platform will begin collecting recruitment information from traders seeking access to certain contracts.
This policy applies to markets that the company considers to be vulnerable to insider information or manipulation and forms part of a broader market integrity initiative announced this week.
Kalshi wants to stop insider trading before it happens
According to the company, the goal is to identify “supposed insiders” and prevent them from participating in certain markets before any trades are executed. Calci said it will use a risk scoring system to identify markets that require additional controls.
The company cited a hypothetical market as to whether OpenAI Or Anthropic will go public first as an example contract where participants may possess non-public information relevant to the outcome.
By collecting employment information before you start trading, everything It says it can better determine whether a trader has access to information not available to the broader market.
Factors considered in the evaluation include corporate performance metrics, product launches, focus of results, national security implications, and potential for manipulation.
The company also applies similar assessments to markets that could pose national security concerns, arguing that additional scrutiny may help reduce the risks of manipulation and potential conflicts between real-world events and market activity.
As Chief Enforcement Officer Robert Denault explained, employment disclosure is only one part of the initiative.
Today we announced that Calci will now require employment information in order to trade on certain markets.
Market integrity is more than just a noble goal for us. This is why we collect identifying information from every trader, why we monitor our markets 24/7, and why…

Part of a broader integrity programme
Kalci said the new measures were recommended by the independent audit and monitoring committee set up to oversee market integrity and implementation programmes.
Along with the job disclosure requirement, the company has introduced a whistleblower portal and expanded reporting tools aimed at helping users report suspicious trading activities directly to its monitoring team.
The company has increasingly focused on execution as prediction markets grow in popularity. According to Kalshi, it opened more than 150 investigations into possible suspicious activities during the first quarter of the year and referred more than 20 cases to law enforcement agencies.
“By implementing these new integrity measures, we continue to lead the industry on the issue of market integrity among federally regulated prediction markets.” He saidAccording to Reuters.
The platform does screen certain categories of users during setup and may restrict access or impose special trading rules on certain politicians, government officials, athletes and individuals associated with sports-related markets.
Prediction markets still face scrutiny over insider trading as the sector expands. The latest cases included an investigation into deals allegedly linked to the former congressman George Santos There are also accusations against a Google employee accused of using company information to bet on a competing platform, Polymarket.
The announcement also comes at a time when prediction market operators are facing increased interest from policymakers. Earlier this month, the House Oversight Committee Required information From both Kalshi and Polymarket about identity verification procedures, trade monitoring systems and measures designed to prevent insider trading.
Against this background, Calci’s latest policy represents an attempt to identify potential internal risks before trading commences rather than relying solely on investigations after the fact.
