Prediction market platform Kalshi is preparing to require users to disclose their employer information before participating in certain sensitive trades, as the company moves to strengthen protections against insider trading and market manipulation.
According to a report from The Wall Street Journal, the new policy will apply to markets considered vulnerable to material nonpublic information, including contracts tied to politics, corporate developments, geopolitical events, and national security matters.
The move comes as prediction markets face growing regulatory scrutiny in the United States following several high-profile insider trading investigations involving platforms such as Kalshi and Polymarket.
Kalshi Expands Insider Trading Safeguards
Kalshi said users participating in high-risk markets will soon need to disclose details including:
- Employer name
- Industry affiliation
- Job function or role
The company reportedly plans to use the information to identify users who may have access to privileged or confidential information capable of influencing contract outcomes.
Kalshi said employment information generally would not be independently verified unless suspicious trading activity is detected.
The company is also introducing a new “risk-scoring” framework designed to classify markets based on their susceptibility to insider trading or manipulation.
Markets involving:
- Political decisions
- Military operations
- Corporate earnings
- Product launches
- Regulatory announcements
could receive elevated monitoring requirements under the updated system.
New Rules Follow Insider Trading Controversies
The tighter compliance measures follow a series of investigations involving suspicious trading activity on prediction markets.
According to recent reports, Kalshi has already referred more than 20 cases involving potential insider trading or market manipulation to federal authorities during 2026.
Among the most widely publicized incidents:
- Former Congressman George Santos was reportedly investigated over trades tied to his attendance at the State of the Union address.
- A YouTube editor connected to MrBeast was fined and suspended after allegedly profiting from privileged knowledge related to online content releases.
- Reports also referenced cases involving military personnel and congressional candidates allegedly using nonpublic information in political or geopolitical prediction markets.
These incidents intensified concerns among regulators and lawmakers about whether prediction markets could become vulnerable to insider trading schemes similar to those seen in traditional financial markets.
Regulatory Scrutiny of Prediction Markets Intensifies
Kalshi’s new compliance measures arrive amid growing federal and congressional scrutiny of prediction market platforms.
In May, the U.S. House Oversight Committee launched an investigation into insider trading risks on both Kalshi and Polymarket.
Lawmakers reportedly requested information about:
- User verification systems
- Geographic restrictions
- Suspicious trading monitoring
- Insider trading enforcement policies
The Commodity Futures Trading Commission (CFTC), which regulates Kalshi, has also faced increasing pressure to strengthen oversight of event-based contracts and political betting markets.
Reuters reported that Kalshi recently established an Independent Surveillance Audit Committee to oversee market integrity and recommend new enforcement measures.
Kalshi Seeks to Differentiate Itself From Offshore Rivals
Kalshi appears to be positioning itself as the most compliance-focused major prediction market platform in the United States.
Unlike offshore competitor Polymarket, Kalshi operates as a federally regulated exchange under CFTC oversight and requires users to complete know-your-customer (KYC) verification procedures.
The company says its new policies are intended to demonstrate stronger institutional safeguards as prediction markets become more mainstream among retail and professional traders.
Kalshi also announced plans to expand whistleblower reporting tools, allowing users to flag suspicious activity directly from market pages.
Prediction Markets Face Growing Legal and Political Pressure
Prediction markets have experienced explosive growth over the past two years, particularly around:
- Elections
- Sports
- Cryptocurrency markets
- Economic indicators
- Geopolitical developments
However, the rapid expansion has also generated controversy over:
- Insider trading risks
- Gambling concerns
- Election integrity
- National security implications
- Market manipulation
Several U.S. states have attempted to challenge Kalshi’s operations, while lawmakers continue debating how prediction markets should be regulated under federal law.
The company has faced legal disputes in states including:
- Arizona
- Nevada
- Ohio
- Washington
where regulators argued certain event contracts resembled unauthorized gambling products.
Insider Trading Becoming Central Industry Concern
Industry analysts say insider trading concerns are becoming one of the defining challenges facing prediction markets as trading volumes increase.
Unlike traditional sports betting, prediction markets often involve real-world events tied to government policy, corporate actions, military developments, and sensitive information flows.
That creates opportunities for traders with privileged access to potentially exploit markets before information becomes public.
Academic researchers and regulators have increasingly focused on methods for detecting suspicious trading patterns across prediction platforms.
Kalshi Expanding Institutional Infrastructure
Kalshi’s latest policy shift reflects a broader effort to build institutional-grade compliance infrastructure as the platform scales rapidly.
The company recently reported surging activity across sports, political, and crypto-related markets, while also launching new products including crypto perpetual futures trading.
Executives argue stronger compliance systems are necessary if prediction markets are to gain broader legitimacy with regulators, financial institutions, and mainstream investors.
Future of Prediction Markets May Depend on Regulation
Analysts believe the long-term future of prediction markets could depend heavily on whether platforms successfully convince regulators they can effectively police insider trading and manipulation risks.
As federal scrutiny intensifies, platforms like Kalshi are increasingly adopting compliance frameworks resembling those used in traditional financial exchanges.
For now, Kalshi’s employer disclosure requirement represents one of the most aggressive insider trading prevention measures yet introduced by a major prediction market operator.
