The prediction markets regulation debate intensified this week as Kalshi and Polymarket introduced new trading restrictions aimed at limiting insider activity.
The timing is critical. Both platforms acted on the same day US lawmakers introduced fresh legislation targeting event-based contracts, raising questions about the future of these rapidly growing markets.
Platforms Respond to Rising Scrutiny
Kalshi outlined new rules that will prevent political candidates from trading on their own elections.
The restrictions also extend to individuals directly tied to sports outcomes, including athletes, referees, and team personnel.
Just hours earlier, Polymarket announced broader measures, targeting users who trade using confidential or stolen information, illegal tips, or any position that allows them to influence outcomes.
Trigger: Suspicious Trading Activity
The policy changes follow mounting criticism over suspicious trades linked to geopolitical events.
Some Polymarket users reportedly placed highly accurate bets ahead of US and Israeli strikes on Iran, as well as a US military operation involving Venezuelan President Nicolás Maduro.
According to Ben Yorke, the Iran-related trades showed patterns consistent with insider knowledge, including multiple accounts used to obscure identity.
Legislative Pressure Builds
The same day, US Senators Adam Schiff and John Curtis introduced the Prediction Markets Are Gambling Act, a bipartisan effort to regulate event contracts more strictly.
The bill seeks to ban contracts that resemble traditional gambling formats, such as sports betting or casino-style games.
If passed, it would prevent platforms registered with the Commodity Futures Trading Commission (CFTC) from offering such products.
Industry Pushback Emerges
Kalshi leadership has pushed back strongly against the proposed legislation.
CEO Tarek Mansour argued that the bill is less about consumer protection and more about preserving existing gambling monopolies.
This highlights a growing divide between prediction market operators and regulators over how these platforms should be classified and governed.
Legal Uncertainty Expands
The regulatory environment is already complex.
Platforms like Kalshi, Polymarket, and even Coinbase are facing legal challenges across multiple US states.
State authorities argue that sports-related event contracts fall under gambling laws and require proper licensing.
Meanwhile, the platforms maintain that their offerings are financial instruments regulated at the federal level by the CFTC.
Market Psychology and Trust Challenges
At the core of the issue is trust.
Prediction markets rely on the assumption that participants operate on publicly available information.
When users suspect insider advantages, confidence in pricing accuracy and fairness begins to erode.
This can discourage participation and reduce liquidity, particularly among retail users.
What Comes Next for Prediction Markets
The combination of internal safeguards and external regulation signals a turning point.
If stricter rules are enforced, platforms may need to redesign contract structures or limit certain markets entirely.
At the same time, clearer regulation could legitimize the sector and attract institutional participants.
