Hamilton takes narrow market lead as Kansas Senate pricing reverses

Action Network reports Adam Hamilton has flipped the Kansas Senate race into a Democratic-favored market, trading at 52 cents on Polymarket and 53 cents on Kalshi after Roger Marshall sat at 61 cents on both exchanges as recently as Wednesday. In the Kansas governor race, Ty Masterson is priced at 75 cents on Polymarket and 73 cents on Kalshi.

According to Action Network, Adam Hamilton has moved ahead in Kansas Senate prediction markets, shifting the race’s pricing in favor of the Democrat.

Hamilton was trading at 52 cents on Polymarket and 53 cents on Kalshi in the report published Oct 31, 2026, at 10:15 PM ET.

Senate contracts change direction

The lead represents a reversal from as recently as Wednesday, when Roger Marshall was priced at 61 cents on both exchanges, according to Action Network.

Hamilton’s latest prices put him narrowly above the 50-cent mark on each platform. The reported figures establish a change in the market favorite, but the supplied summary does not identify what drove it.

Governor market shows a wider advantage

In the Kansas governor race, Action Network reported Ty Masterson at 75 cents on Polymarket and 73 cents on Kalshi.

Masterson’s contracts therefore stood substantially higher than Hamilton’s on both platforms, distinguishing the governor market’s pricing from the narrower Senate contest.

What it means for prediction markets

  • A new Senate favorite: Hamilton’s 52-cent and 53-cent prices show Democratic-favored pricing on both exchanges after Marshall’s 61-cent position on Wednesday.
  • Small differences between platforms: Hamilton was priced 1 cent higher on Kalshi than on Polymarket; Masterson was priced 2 cents higher on Polymarket than on Kalshi.
  • Limited context for the reversal: The supplied reporting gives price snapshots, but no explanation for the move or information about trading volume.
