Kalshi prices recorded Monday afternoon put Democrat Adam Hamilton at a record 63 percent against Republican incumbent Roger Marshall in Kansas, according to NextPredict. Hamilton’s pricing rose 23 percentage points over the past week, shifting the market in his favor.
Kansas leads a broader Senate repricing
The Kansas move marks a sharp change over a short period. Hamilton’s weekly gain brought him above the market’s halfway point and to his highest recorded level, according to NextPredict.
In Texas, Democrat James Talarico reached 75 percent against Ken Paxton. NextPredict reported that his pricing had risen 34 percentage points since the Republican primary runoff.
Iowa’s Senate contest remained evenly divided at 50-50, according to NextPredict. That pricing contrasted with the Democratic advantages reflected in the Kansas and Texas markets.
What it means for prediction markets
- Kansas has shifted substantially: Hamilton’s record 63 percent followed a 23-percentage-point gain in one week.
- The comparison periods differ: Talarico’s 34-percentage-point increase covers the period since the Republican primary runoff, rather than the past week.
- Iowa remains balanced: Its 50-50 pricing shows no market favorite, unlike the reported positions in Kansas and Texas.
- These are market snapshots: The reported prices describe market expectations, not election outcomes.
