Kalshi Bans Ex-Congressman George Santos for Manipulating Prediction Market

This ban signals that prediction platforms are serious about policing insider-style trading, even when the underlying event is a public speech. It matters because it tests how these markets define and enforce manipulation beyond traditional financial rules, potentially shaping their credibility and regulatory treatment. The key question is whether Kalshi's action sets a precedent for other exchanges and broader market integrity standards, especially as political event contracts gain traction.
