The Edge in Political Markets
Political markets frequently show divergence between platforms because they attract different trader bases. Kalshi tends to draw more institutional and financially-sophisticated traders; Polymarket draws a global crypto-native audience.
These different perspectives create pricing gaps — which is exactly what we track daily. Check the Kalshi movers page for today's biggest political market moves.
