About this episode

The episode discusses insider trading concerns on prediction markets, particularly in light of recent bets related to the Iran war.

A series of suspiciously well-timed Iran war bets placed on Polymarket have revived concerns about insider trading on prediction markets. But enforcement is something of a gray area. Marketplace’s Meghan McCarty Carino joins Kimberly to explain the relatively recent history of insider trading laws at the CFTC and what it could mean for prediction market platforms. Plus, the debate over whether insider trading on these markets is actually a good thing.
