CNN raises insider trading concerns over midterm prediction markets

CNN published a report raising concerns that the expansion of prediction market platforms like Kalshi and Polymarket has made it easier to profit from insider information. The article focuses on markets tied to midterm election endorsements, rallies, and debates.

Regulatory and reputational risk for Kalshi and Polymarket if insider-trading narratives gain traction in Congress or at the CFTC. Could trigger new disclosure requirements or contract restrictions on politically sensitive markets.
