Earlier this week, Kalshi announced the implementation of new guardrails, which will attempt to prevent insider trading in manipulation in its prediction markets related to politics and sports.

What's the Scoop?

Automated Detection: Kalshi has implemented new guardrails using "state-of-the-art technology" to preemptively block politicians, athletes, and other relevant people from trading in certain politics and sports markets. The tools should preemptively block political candidates from trading their own campaigns, and prohibit individuals involved in college and professional sports (including athletes, personnel, and referees) from trading markets associated with sports in affiliated leagues they are involved in.
Whistleblower Feature: To supplement its automated detection systems, Kalshi is also implementing "whistleblower functionality" within individual markets, essentially a report button that will make it easily accessible for members of the public to flag potential compliance violations.
