Kalshi banned a California politician from its platform after he bet on his own run for governor, which Kalshi treats as an insider trading violation.
Kalshi said the politician placed about $200 in bets on his candidacy and posted about the trade on X, which helped trigger the enforcement action.

Kalshi’s head of enforcement, Robert DeNault, described the case as a breach of the platform’s insider trading rules.
Kalshi did not name the individual in its public statement. However, multiple reports identified him as Kyle Langford, who previously ran for California governor and is now running for Congress in California’s 26th Congressional District.
Kalshi said the penalty included a five year suspension and a $2,000 fine. The company also said the account did not withdraw profits.

Kalshi also penalized a YouTube editor accused of trading on information tied to YouTube stream related markets.
Kalshi said the trader put about $4,000 into those markets between August and September 2025.
Kalshi said its surveillance systems flagged the account for unusual performance in low odds markets.
The company described the results as “statistically anomalous,” and it said it used platform information, plus help from other traders, to identify where the editor worked.
“Our surveillance systems flagged his near perfect trading success on markets with low odds, which were statistically anomalous,” Kalshi said in its statement.
Kalshi did not name the editor in its announcement. Still, several outlets said mainstream reporting identified the person as Artem Kaptur, an editor linked to MrBeast.
Kalshi said the penalty included a two year suspension and a fine around $20,000, although one report put the fine at $15,000.

Kalshi said it reported the cases to the Commodity Futures Trading Commission, which regulates the platform.
It also said it has investigated about 200 cases and has more than a dozen active cases.
Earlier this month, Kalshi said it tightened surveillance by forming a surveillance audit committee. It also said it partnered with Solidus Labs to detect and investigate market abuse.
The disclosure landed during rising scrutiny of prediction markets, including state legal fights over whether some contracts look like gambling products.
CFTC Chair Michael Selig recently pointed to the agency’s role in policing fraud and safeguarding markets.
Reports also tied his comments to new CFTC work with industry participants focused on catching insider trading in prediction markets.
