Colorado Senate primary margin of victory?

Prediction market odds often diverge from traditional polling averages because they incorporate real-money incentives and continuous price discovery. While polls capture voter sentiment at a single point in time, this market allows traders to update their expectations dynamically as new information emerges. Polls may show candidate support levels, but the margin outcome here depends on turnout, late-breaking developments, and campaign momentum—factors that markets price in through active trading. Comparing the implied probability from current odds to recent polling can reveal whether traders expect a tighter or wider final margin than surveys suggest.
