Compare candidates

See up to four candidates side by side: how likely each is to be nominated, to win the presidency, and to win it if nominated.

A comparison, not a matchup. Each figure is a candidate’s own chance, from their own market prices, not their chance against anyone else on this page. Nothing here says who would win if two of them faced each other.

Hourly midpoint prices. Each line is a candidate’s own chance if nominated, not their odds against the others. Gaps mean the candidate wasn’t ranked at the time or no price was recorded.
