Kalshi, a New York-based prediction market platform, announced on Tuesday, June 9, 2026, that it will mandatorily require some traders to disclose their employers to prevent insider trading. The new compliance protocols target sensitive markets such as corporate earnings, national security, and geopolitical developments where traders might possess material nonpublic information.
The decision follows recommendations from the platform’s Independent Surveillance Audit Committee, led by Brian Nelson, the former U.S. Treasury undersecretary for terrorism and financial intelligence.
The federally regulated exchange is attempting to close gaps in its surveillance system that previously permitted “presumptive insiders” to place bets before they could be caught. Under the new rules, Kalshi will assign a risk score to specific markets.
If a market triggers a high-risk benchmark, any participant must complete an online form identifying their employer. These updates are effective immediately for high-stakes contracts, with a full rollout scheduled for the coming weeks.
This move highlights a broader shift in how digital trading platforms manage transparency. For example, market confidence often hinges on geopolitical shifts, making information regarding the war in Iran or national policy decisions highly valuable. By screening out those with direct corporate or government ties, Kalshi aims to protect the integrity of its order books from unfair advantages.
Risk scoring framework for sensitive prediction markets
Kalshi has developed a nuanced risk-scoring framework to determine which markets require employment verification. The system evaluates three primary factors: corporate Key Performance Indicator (KPI) risk, outcome concentration risk, and the overall importance of the market to the public. If a market is tied to a specific company’s performance or a confidential policy decision, the “employer check” requirement is automatically activated.
Traders eyeing markets related to corporate earnings or new product introductions will now face this extra layer of friction. While Kalshi already collects standard identification data like dates of birth and partial Social Security numbers, this is the first time the company has mandated employment disclosure.
The goal is to identify individuals who might have advance knowledge of a private event before the trade is ever executed on the exchange.
The company stated it will not proactively verify every employer listed on these forms. But, if a trader’s activity triggers a internal investigation for suspicious patterns, Kalshi will demand official proof of employment. And, any trader found to be an employee of a relevant firm in a restricted market will face immediate blocks and potential legal referrals.
Expanding the scope of prohibited participants
The Independent Surveillance Audit Committee, which also includes Daniel Taylor of the Wharton School and Lisa Pinheiro of the Analysis Group, has pushed for more aggressive deterrence. This year alone, Kalshi opened over 150 investigations and blocked more than 100 trades using preliminary screening tools. In the first quarter of 2026, the firm submitted over 20 referrals to federal regulators and law enforcement agencies.
Kalshi already maintains a strict “no-go” list for certain public figures to ensure fairness. Members of Congress, the president, cabinet officials, and federal judges are currently prohibited from using the platform. Similar restrictions apply to athletes and coaches in sports-related markets. As sportsbooks increasingly integrate odds analysis into mainstream finance, the pressure to maintain professional boundaries has never been higher.
New whistleblower and facial recognition tools
Beyond employment checks, Kalshi is introducing an in-platform “report insider trading” button. This feature allows the community to flag suspicious price movements or leaked information directly from a market’s page. These reports feed into a dedicated intake system monitored 24/7 by a specialized surveillance team. This crowdsourced approach complements the platform’s recent addition of facial-recognition verification for all new accounts.
The exchange is also deepening its technical partnerships with Solidus Labs and IC360 to monitor for market manipulation. IC360 currently works with major leagues like the NHL and NCAA to screen sports professionals, a model Kalshi is now adapting for corporate and political insiders. These layers of defense represent a significant escalation in the war against information asymmetry in the prediction space.
What this means for the future of regulated prediction trading
The tightening of rules at Kalshi is a clear response to mounting pressure from lawmakers and federal prosecutors. As prediction markets grow in volume, the risk of they being used for “legalized” insider trading has become a central concern for the Commodities Futures Trading Commission (CFTC). By self-regulating through employer checks, Kalshi hopes to prove that it can manage these risks without further government intervention.
Traders can expect more platforms to adopt similar heighted KYC (Know Your Customer) standards in the near future. While the extra paperwork might frustrate some casual users, the platform argues that a clean market is necessary for long-term growth.
If Kalshi can successfully filter out insiders, it may pave the way for more complex corporate and geopolitical contracts to be approved for public trading later this year.
