Kalshi fines first insider-trading cases hit MrBeast editor and a candidate

Kalshi disclosed its first insider-trading penalties: a $20,000 fine and two-year suspension for MrBeast editor Artem Kaptur after he traded about $4,000 on YouTube streaming markets, and more than $2,000 in penalties plus a five-year ban for California gubernatorial candidate Kyle Langford after trading on events he appeared to influence. Kalshi says it reported both cases to the CFTC and has opened over 200 investigations in the past year, highlighting growing concerns about insider trading in prediction markets and regulatory scrutiny.
