Kalshi, the federally regulated prediction market platform, will ban athletes, coaches, and political candidates from trading on markets directly tied to their own domains, according to a report from Axios. The policy targets conflict-of-interest risks that mirror insider-trading concerns in traditional financial markets.
The move comes as prediction markets face growing scrutiny from U.S. lawmakers. Senators have begun pushing to curb insider trading on prediction platforms, prompting both Kalshi and offshore competitor Polymarket to act preemptively.

Who Is Banned and What Markets Are Off-Limits
The restriction applies to three categories of participants. Athletes and coaches are prohibited from placing trades on sports prediction markets where their own performance or decisions could influence the outcome. Political candidates face the same exclusion from election-related markets.
The logic is straightforward: a basketball player betting on their own game, or a Senate candidate wagering on their own election, holds material non-public information that ordinary traders do not. Allowing such trades would undermine the integrity of the market itself.
Axios reported that Kalshi plans to enforce the ban through identity verification and account review processes. The policy targets the specific market categories tied to a participant's domain, not a blanket trading prohibition. An athlete could still trade on economic event markets, for example, just not on sports outcomes they can influence.
The timing is notable. Multiple news outlets have confirmed that both Kalshi and Polymarket rushed to implement insider-trading bans as senators moved to impose external restrictions on the prediction market industry.
Conflict-of-Interest Rules Mirror Sports Betting Integrity Standards
Kalshi's new policy follows a principle already well established in U.S. sports gambling. The NCAA, NFL, and MLB all prohibit athletes from wagering on their own games. The reasoning is identical: participants with direct influence over outcomes cannot be allowed to profit from that influence in betting markets.
Prediction markets, however, operate under a different regulatory framework. Kalshi is regulated by the Commodity Futures Trading Commission (CFTC), which treats prediction market contracts as legally sanctioned financial instruments. This makes the insider-trading analogy more than rhetorical. In traditional commodities and securities markets, trading on material non-public information is a federal offense.
For political candidates, the conflict is equally structural. A candidate trading on their own election outcome has a direct financial incentive tied to campaign decisions, from debate strategy to voter outreach timing. This creates a scenario where personal financial gain could theoretically influence governance decisions, a concern that has drawn attention from lawmakers examining the growing role of prediction markets in political forecasting.
Context
"You can't bet on a game you control."
Kalshi's new rule applies the logic of insider-trading law to prediction markets: participants who can materially influence an outcome, an athlete in their own sport, a politician in their own race, are excluded from trading on that outcome.

What This Means for Kalshi's Position in Regulated Prediction Markets
Kalshi secured CFTC approval for election prediction markets in 2024 after a protracted legal battle, becoming the first federally regulated platform to offer political event contracts in the United States. Since then, the platform has expanded into sports, entertainment, and economic event markets.
The self-imposed insider-trading ban signals a deliberate effort to stay ahead of regulatory action. By voluntarily restricting conflicted participants, Kalshi positions itself as a platform that takes market integrity seriously, a posture designed to maintain CFTC goodwill and reduce the likelihood of heavier external rules.
This compliance-first approach also differentiates Kalshi from offshore competitors. Polymarket, the largest prediction market by volume, operates outside U.S. regulatory jurisdiction. While Polymarket has also moved to implement its own insider-trading restrictions, it does so without the same regulatory obligations that come with CFTC oversight.
For readers tracking the intersection of regulated fintech and crypto-adjacent infrastructure, the distinction matters. Prediction markets are increasingly relevant to the broader on-chain economy, with tokenized event contracts representing a growing category of decentralized finance applications.
Kalshi's decision to proactively ban insiders rather than wait for legislation reflects a calculated bet: that self-regulation now will preserve its operating license and competitive advantage as Washington continues to debate how prediction markets should be governed. The platform's approach mirrors the strategy some crypto firms have adopted in DeFi security, where proactive compliance measures aim to build trust with regulators before enforcement actions force the issue.
Whether the voluntary ban satisfies congressional critics remains an open question. Senators pushing for prediction market regulation have indicated they want statutory restrictions, not just platform-level policies. The next concrete milestone will be whether pending legislation advances through committee in the current session.
