Prediction market operator Kalshi has introduced new compliance measures that could require some traders to verify their employment before participating in certain markets, according to policies announced by the company this week.
Today, we announced that Kalshi will now require employment information in order to trade in certain markets.
Market integrity is a more than just a lofty goal for us. It’s the reason we collect identification info from every trader, why we surveil our markets 24/7, and why we…

Robert DeNault is a lawyer and Head of Enforcement at Kalshi. He announced the new employment-verification requirement as part of the company’s efforts to strengthen market integrity and prevent misconduct.
The changes are intended to strengthen oversight of markets vulnerable to insider trading or manipulation. Kalshi said traders seeking access to markets deemed higher risk may be asked to disclose employment information so the company can assess whether they may have access to material non-public information related to market outcomes.
Kalshi said it has introduced a market risk-review framework, expanded screening procedures, and new reporting tools for suspected abusive trading activity. The company said the measures took effect immediately following recommendations from its independent Surveillance Audit Committee, established in February to oversee market integrity and enforcement practices.
New Review Process Targets Insider-Trading Risks
Alongside the trader-verification requirements, Kalshi said it has implemented a formal risk-review process for all proposed markets before they are listed. According to the company, the review considers factors including the potential for insider access to information, the number of individuals capable of influencing an outcome, regulatory concerns, and possible national-security implications.
Markets tied to corporate events, product launches, or other situations where non-public information may play a role could face heightened scrutiny under the framework.
The announcement comes as prediction markets attract increasing attention from regulators, policymakers, and industry observers. Critics have raised concerns that certain contracts may create opportunities for informed trading, particularly when a limited number of individuals possess information that could affect a market’s outcome.
Kalshi did not disclose how frequently proposed markets are rejected under the new review process or provide additional details about how employment information will be evaluated.
Company Reports Increased Enforcement Activity
The company also released enforcement data covering the first quarter of the year. Kalshi reported conducting more than 150 investigations, blocking more than 100 suspected insider-trading attempts, referring more than 20 matters to law-enforcement agencies, and issuing five disciplinary actions.
Those figures were provided by the company and could not be independently verified. Kalshi did not disclose further information about individual cases or the outcomes of referrals made to authorities.
The announcement follows several recent developments at Kalshi, including the launch of CFTC-regulated Bitcoin perpetual futures in the United States after receiving regulatory approval in late May. The company has also expanded its public-policy efforts through initiatives such as Americans for Fair Markets, a group launched with support from figures connected to President Donald Trump’s political network.
Whether employment-verification requirements will significantly reduce insider-trading risks remains uncertain. Industry participants and regulators continue to debate how prediction markets should balance open participation with safeguards designed to protect market integrity.
Conclusion
Kalshi’s new compliance measures mark a significant expansion of oversight within the prediction-market industry. The company is seeking to address concerns about insider trading and market manipulation through stricter trader screening and market reviews. The changes come as prediction markets face increasing scrutiny from regulators, policymakers, and industry observers. While the measures may strengthen safeguards against the misuse of non-public information, their long-term effectiveness remains uncertain. The initiative highlights the broader challenge of balancing open market participation with the need to maintain market integrity and investor confidence.
