Click a book's logo to see only its price changes, with every other book's price at that moment (faded). Click it again for all changes.

Each book's main line: its most even spread; period lines from 25 October 2026. Shaded blue when the market moved toward this selection (a shorter price, or a line that asks more of it), orange when it moved away; a book's first price isn't shaded. Kalshi reprices by a cent at a time, so a Kalshi change shows only once it's a point of implied chance or a line away from the last one shown; its prices include our estimate of Kalshi's fee. We check each book every 10 minutes near the game, less often further out. Started games show prices up to the start.
