Former Rep. George Santos has been given a lifetime ban from the prediction market Kalshi. This ban comes after insider trading investigations. Santos is a Republican nominee in a competitive House race.

Another candidate, Laurie Buckhout from North Carolina, admitted to betting on her own campaign, calling it a "dumb mistake". She took action after learning there was an issue.

Further details on these developments are available from the source, including information on the growing concern of political insider trading on prediction platforms.
