Kalshi, one of the leading prediction market firms, has issued another set of insider-trading disciplinary actions against users accused of making improper trades based on their inside knowledge of their own political situations, including an ex-reality TV star in Virginia who said he did it intentionally.

"Cases like these demonstrate Kalshi’s commitment to policing all types of unfair or improper trading on our platform," the company said in a statement posted on its website on Wednesday. "Regardless of the size of a trade, political candidates who can influence a market based on whether they stay in or out of a race violate our rules."

Two of the cases were said to admit they were in the wrong, and Kalshi — a trading platform regulated by the Commodities Futures Trading Commission — said they received a more modest response than the Virginia politician who defied the process. These are the three:

• Mark Moran, a former investment banker and participant on HBO's Fboy Island, said in a Wednesday post on social media site X that he placed the Kalshi bet on his own candidacy in the Virginia U.S. Senate race to expose the company for "destroying young men" and pretending to care about enforcement. "As senator, I will go after Kalshi and impose significant penalties on them — 25% — a vice tax — to pay down our national debt."Kalshi imposed a five-year suspension, $6,229 fine and disgorgement of any profits, noting: "As a candidate, Moran qualified as a direct decision maker for this contract and had direct influence on the outcome of the underlying event."
• Matt Klein, a state lawmaker who is running as a Democrat for a U.S. House seat in Minnesota, also made a bet on his own candidacy, but he settled with Kalshi, accepting a 5-year suspension and a $540 penalty.Kalshi concluded that "Klein cooperated with the inquiry into this trading activity and agreed to finally resolve this matter by accepting the Compliance Department’s conclusions, paying a financial penalty, and accepting a restriction from trading on the exchange."
• Ezekiel Enriquez, like Klein a candidate for a U.S. House seat, was accused of betting on the details of his own election in Texas. The conservative Republican and supporter of President Donald Trump was said to cooperate similarly with Kalshi and was given a 5-year suspension and $784 fine.

Kalshi's rules are set out in its website's compliance section. While it's not detailed in the firm's member agreement, fines and suspensions like those given in these latest cases are detailed within Kalshi's corporate "rule book," and the determination of penalties lets the company fine a member at a level "sufficient to deter recidivism" — meaning enough to keep people from doing it again.

The company had begun publicly announcing insider-trading matters with the February exposure of cases that included a producer of the popular online entertainer, Mr. Beast. The CFTC has praised the platform for being a front-line enforcer, though the agency has noted that such cases could also trigger federal enforcement.

The events-contract industry has been under tight scrutiny during its explosive rise in popularity. The businesses are still wrestling with doubts from prominent critics that they can manage contracts without insider abuse.

Kalshi, in particular, has also been at the forefront of legal clashes with state regulators and law enforcement officials over whether its activity is legally permissible in their states. CFTC Chairman Mike Selig has come to the industry's aid by insisting that the activity belong solely under the federal regulator's jurisdiction, and he's begun fighting that point in court.
