Kalshi targets insider trading risks with new compliance framework
Synopsis
Kalshi has launched new compliance controls that may require employer disclosure from traders participating in certain high-risk prediction markets. The measures include enhanced surveillance tools, market risk assessments and whistleblower reporting channels, reflecting increasing regulatory attention on insider trading risks as the prediction market industry continues to expand.
Key Highlights
- Kalshi may require employer disclosure for traders in selected high-risk markets.
- New risk-scoring system targets contracts vulnerable to insider information.
- More than 20 suspicious trading cases were referred to authorities in 2026.
- Industry trading volume exceeded $40 billion in 2025, according to KPMG.
- New reporting tools and whistleblower channels expand market surveillance efforts.
New compliance rules are coming to prediction market operator Kalshi, and some traders may have to disclose their employer if they wish to trade in particular markets. The decision from the company comes as it faces concerns about insider trading and market manipulation.
The new measures will be applicable to contracts which are classified by Kalshi as being subject to higher risks of the misuse of non-public information. These may relate to corporate news, product launches, government announcements, national security issues, and others at which individuals might possess informational advantages due to their insider positions.
The reforms appear at a time of rising interest from regulators, policymakers, and financial market watchers in the US. Prediction markets have experienced rapid growth over the last two years, diverging from their primary use in election trading toward commercial, economic, and geopolitical events.
Compliance measures that accompany market growth
Kalshi will implement a risk-scoring mechanism that will evaluate individual markets, in order to determine which require additional safeguards. Individuals wishing to gain access to contracts of a higher risk may have to reveal their employer in order to reveal possible conflicts of interest.
The company will also unveil a whistleblower program and new market level reporting features which allow users to report suspicious activity. A dedicated surveillance team will continue to monitor market transactions occurring on its platform.
The firm states that in 2026 it already passed more than 20 cases of suspected insider trading or market manipulation onto law enforcement and regulators.
The industry moves toward stronger regulation
The proposed regulations come on the heels of recommendations by Kalshi's independent Surveillance Audit Committee, which recently published its initial market integrity review.
The entire prediction market sector has seen enormous growth in size. An article produced by KPMG in 2026 with the report titled Prediction Markets: Paths to Entry estimated that market turnover at the major prediction markets increased from $9 billion a year earlier to more than $40 billion.
The trends demonstrate to businesses, investors, and politicians both within the U.S. And Australia that the prediction market arena is rapidly changing from a specialist trading environment into more significant financial arenas that bear many of the same regulatory expectations that apply to markets which are already subject to regulation.
