Kalshi Tightens Trader Screening as Insider Betting Concerns Reach Prediction Markets

A trader hoping to place a wager on a sensitive event at Kalshi may soon have to reveal more than just their market position.

The prediction market operator said Tuesday that it has begun collecting employment information from users participating in markets considered especially vulnerable to manipulation or insider knowledge. The move forms part of a broader compliance overhaul as the rapidly expanding industry faces increasing scrutiny over whether traders can profit from privileged information.

Kalshi, based in New York, has built its business around allowing users to trade on the outcomes of future events, from elections and sporting contests to geopolitical developments. As trading activity has surged, so have concerns that participants with access to non-public information may gain an unfair advantage.

The company said the new requirements emerged from recommendations made by its Independent Surveillance Audit Committee, which was established earlier this year to examine market integrity risks.

New Safeguards for High-Risk Markets

At the center of the overhaul is a risk-scoring framework designed to identify markets most susceptible to manipulation.

For markets that receive elevated risk ratings, Kalshi will require additional background information from traders, including employment details that could reveal whether a participant has access to information unavailable to the broader public.

The company is also introducing a dedicated around-the-clock whistleblower reporting channel intended to help identify suspicious trading activity before it distorts market outcomes.

Kalshi’s enforcement leadership described the measures as an effort to strengthen oversight standards in federally regulated prediction markets, a sector that has grown far faster than the compliance structures surrounding it.

Industry Faces Growing Insider Trading Questions

The announcement arrives as prediction markets find themselves under an increasingly bright spotlight from regulators and law enforcement agencies.

Recent prosecutions have highlighted how insider knowledge could potentially be converted into profits on platforms that allow users to speculate on real-world events.

In April, U.S. prosecutors charged a member of the country’s special forces with allegedly placing trades on Polymarket linked to the capture of former Venezuelan president Nicolás Maduro before the operation took place.

A month later, authorities accused a software engineer at Google of using access to internal company information to make prediction market trades related to search engine outcomes.

Neither case involved Kalshi directly, but both underscored concerns about how difficult it can be to police markets where valuable information may be known by only a small number of individuals before becoming public.

Political Betting Draws Scrutiny

Kalshi has encountered its own challenges.

Earlier this year, the company disciplined three political candidates after determining they had wagered on races in which they were participants. The penalties included fines and account suspensions.

The platform also referred former congressman George Santos to authorities after identifying wagers connected to whether he would attend President Donald Trump’s State of the Union address, according to reports published at the time.

Those incidents reinforced a broader concern facing prediction market operators: participants who possess unique insight into an outcome can potentially influence pricing in ways that undermine confidence in the market itself.

A Booming Business Meets Regulatory Reality

The integrity push comes as prediction markets continue to attract extraordinary amounts of money.

Kalshi and its crypto-based rival Polymarket have transformed from niche platforms into multibillion-dollar businesses in just a few years. Combined monthly trading volume reached roughly $24 billion in April, according to data analyzed by the Pew Research Center, compared with less than $5 billion seven months earlier.

The pace of growth has increased pressure on operators to demonstrate that market activity reflects genuine forecasting rather than exploitation of privileged information.

Kalshi’s latest enforcement figures suggest the company is already devoting significant resources to that effort. During the first quarter, it launched more than 150 investigations, blocked over 100 suspected insider-trading attempts, and referred more than 20 matters to law enforcement agencies.

As prediction markets move deeper into mainstream finance and public discourse, the industry’s next challenge may not be attracting users. It may be convincing regulators and traders alike that the people placing bets are competing on insight and analysis rather than information nobody else has.
