Kalshi says it fined a MrBeast editor and a politician for insider trading

Kalshi, the prediction betting market, has disclosed its first fines for insider trading, as reported earlier by The Wall Street Journal. In addition to handing down a $20,000 fine to a MrBeast editor, Kalshi also charged a California gubernatorial candidate over $2,000 after a video on X "appeared to show him trading on his own candidacy."

In a notice on Wednesday, Kalshi claims MrBeast editor Artem Kaptur traded about $4,000 on YouTube streaming markets, violating its insider trading rules.
