Kalshi Hands Out Bans For Insider Trading, Including On A Political Candidate

Kalshi has concluded two internal investigations tied to trading activity on its prediction markets platform, resulting in multi-year bans and financial penalties.

Tarek Mansour, Kalshi’s co-founder and CEO, disclosed the news in a LinkedIn post on 25 February following public scrutiny of insider trading on the market. 

The first case concerned a political candidate who placed $200 in trades on contracts linked to his candidacy for Governor in California. The candidate later publicised the trades on social media.

Kalshi’s investigation determined that the individual violated several company policies on participating in the markets. The candidate has since announced that he is withdrawing from the California governor’s race to run for a seat in Congress.

The company imposed a five-year trading ban on the candidate and levied a fine ten times the original amount.

Internal probe finds further breach involving company insider

The second investigation involved one of Kalshi’s insiders who traded roughly $4,000 in contracts around YouTube streaming metrics. The company found that the employee’s activity breached its insider trading restrictions.

Following its review, the company issued a two-year trading ban and imposed a financial penalty equal to five times the amount of the trades in question.

Kalshi’s compliance team gathered evidence and transaction records before determining there were sufficient grounds to establish violations in both cases. The company stated that it coordinated with law enforcement authorities before finalising the sanctions.

Kalshi reiterated that no financial exchange is immune from misconduct of this nature. However, it remains focused on detecting and preventing improper trading activity across its markets.

Commodity Futures Trading Commission confirms oversight authority

In a separate statement, the Commodity Futures Trading Commission confirmed that Kalshi had taken action through its internal compliance framework. The regulator emphasised that it retains full enforcement authority under the Commodity Exchange Act over trading on designated contract markets, including prediction markets.

The Commission highlighted practices that fall within its authority, including the misappropriation of confidential information in breach of a duty of trust, or insider trading. It also mentioned prohibitions of pre-arranged, non-competitive trading and the ban of wash trading.

The CFTC cited disruptive trading practices prohibited under Section 4c(a)(5) of the Commodity Exchange Act. It further pointed to anti-fraud and anti manipulation provisions embedded in federal commodities law.

Past enforcement actions illustrate how these statutory provisions have been applied in previous cases. These two enforcement episodes draw attention to the tension exchanges face when offering contracts linked to political campaigns and media performance metrics while maintaining market integrity.

Kalshi seeks temporary restraining order in Utah federal lawsuit

Separately, Kalshi is pursuing federal litigation in Utah in response to actions taken by state officials. Court filings show that the company has requested a Temporary Restraining Order shortly after initiating its lawsuit.

On 23 February, Kalshi filed a complaint in federal court challenging measures adopted by Utah officials. The suit is grounded in federal pre-emption principles and the Supremacy Clause of the US Constitution.

Kalshi is seeking a declaratory judgment and permanent injunction to prevent further enforcement efforts at the state level in this lawsuit. The requested TRO would remain in place while the case proceeds, alongside a motion for a preliminary injunction.
