The CFTC-regulated prediction market platform Kalshi has banned a former California gubernatorial candidate for insider trading. The politician, identified as Kyle Langford, placed an approximately $200 bet on his own election odds and posted about it online. Separately, a YouTube editor employed by MrBeast was fined roughly $20,000 for similar violations. The enforcement actions coincide with increased regulatory scrutiny, leading the CFTC to establish a new advisory focused on prediction markets.
A former contender for governor of California has been banned from Kalshi after betting on his own candidacy. The prediction market platform said this violated its insider trading rules.
The politician bet about $200 on his candidacy and posted about it on X. This led to a five-year suspension and a $2,000 penalty according to a statement from Kalshi’s head of enforcement.
Kalshi did not name the politician but said he is now running for Congress. The description appears to fit Kyle Langford, who is running for election to the US House.
In an X post published on May 25, 2025, Langford shared a video of himself placing the bet. Kalshi said the account did not withdraw any profits and reported the case to the CFTC.
Meanwhile, Kalshi also penalized a YouTube editor who traded about $4,000 on YouTube stream markets. This violated insider trading rules, resulting in a two-year penalty and a roughly $20,000 fine.
Kalshi’s surveillance systems flagged his statistically anomalous trading success. With help from other traders, the platform concluded he likely had access to material non-public information.
While Kalshi didn’t name the editor, mainstream media have reported it to be Artem Kaptur. Kaptur is an employee of the popular YouTuber MrBeast.
Kalshi, a Commodity Futures Trading Commission-regulated platform, said it has investigated 200 cases. It has frozen several flagged accounts and has more than a dozen active cases.
Earlier this month, Kalshi strengthened surveillance by establishing an audit committee. It also partnered with crypto trading surveillance platform Solidus Labs to detect market abuse.
Those efforts respond to increased regulatory scrutiny as prediction markets enter the mainstream. US lawmakers introduced a bill last month to restrict trading by government insiders.
On Thursday, CFTC Chair Mike Selig said the agency established a prediction markets advisory. The advisory will collaborate with industry participants to catch insider traders.
Selig warned that those engaging in insider trading will face consequences. “Let me be clear: if you attempt to engage in manipulation, fraud, or insider trading, we will find you and take action,” he stated.
