Prediction market operator Kalshi has suspended and fined two individuals in separate insider trading cases, as the company reports expanded enforcement activity across its platform.
The company said an editor for YouTube streamer MrBeast and former California gubernatorial candidate Kyle Langford face disciplinary actions for violating its trading rules. Kalshi said it has opened 200 investigations into potential violations over the past year, with more than a dozen becoming active cases.
MrBeast editor suspended and fined
Kalshi said it imposed a two-year suspension and a financial penalty equivalent to five times the trade size on Artem Kaptur, an editor who worked for MrBeast. The company disclosed a more than $20,000 fine tied to trading activity of approximately $4,000 in YouTube-related markets.
According to Kalshi, Kaptur placed bets based on “material, non-public information” obtained through his role as a video editor. The company said its surveillance systems flagged “near-perfect” and “statistically anomalous” trading wins. Users also alerted the operator to abnormal trading activity.
“In both of these cases, our systems flagged the trades, and our surveillance team froze the traders’ accounts. Neither trader withdrew any profits,” Kalshi said. “These penalties are not indicative of future penalties – everything depends on the case, including amount traded and rules violated.”
Bobby DeNault, who leads Kalshi’s enforcement efforts, said in a post: “No financial exchange is immune from bad actors. Not stock exchanges, not banks, not prediction markets.”
“We’re committed to deterring and finding the bad actors, manipulators, and those who willingly cheat,” he added.
A spokesperson for Beast Industries said the company had “no tolerance for this behaviour, whether by contestants or our own employees”. The spokesperson added that Beast Industries has a policy barring employees from using proprietary information and has initiated an independent investigation.
“We welcome Kalshi – and hopefully others in the space – also taking this issue seriously, but it only works if they are willing to communicate their findings,” the spokesperson said.
Political market violations
In a separate case, Kalshi fined Langford more than $2,000 and suspended him for five years after he placed bets on his own candidacy in the California governor’s race. The company said its rules prohibit political candidates from wagering on their own elections.
“As a candidate in a race, you can (and probably should) follow and use Kalshi’s market forecast, but you should not trade on it,” the company said in a post. “Punishment: 5-year ban + financial penalty (10 times the initial trade size). Note: this candidate recently announced he is no longer running for Governor and is now instead running for Congress.”
Separately, Stephen Cloobeck, a donor to Democratic candidates and former gubernatorial contender, was barred from trading Kalshi event contracts related to California’s governor’s race after publicly discussing wagers on Rep. Eric Swalwell.
Cloobeck placed a $1,000 bet on Swalwell to become governor and another $2,000 on Swalwell to defeat San Jose Mayor Matt Mahan in the primary. His restriction applies only to the California gubernatorial market.
Kalshi said it has reported the Kaptur and Langford cases to the Commodity Futures Trading Commission. The CFTC’s Division of Enforcement noted that while the company addressed the matters internally, the Commodity Exchange Act grants the division authority to act.
“In appropriate cases, the Division will investigate and prosecute violations, as it always has with respect to conduct occurring on designated contract markets (DCMs),” the division said. “The Division continues to coordinate with DCMs regarding their enforcement dockets and referral of appropriate potential violations to the Division for investigation.”
Prediction markets have drawn hundreds of millions of dollars in wagers on events, including the 2024 US presidential election. The sector faces ongoing scrutiny over the use of inside information and regulatory standards compared with traditional financial markets.
