Only outcomes with a live two-sided quote are shown, and 5 contracts trading under a cent are left off. Polymarket prices are matched to this market by outcome name; where a name has no counterpart the cell is left empty rather than guessed. Prices as of Thu, 17 Sep 2026 04:07:58 UTC.
The market says 29%. It got there by making everyone who disagreed put money behind it. You do not have to, so this is the cheap version of the same question, and the interesting number is how far the two drift apart.

What this market has cost every day since 21 December 2025, taken from the exchange's own published history. The line is the mid price, halfway between what a buyer would pay and a seller would take.

The other 1 contract in this field is left off the chart rather than drawn in a colour nobody could tell apart; it is all in the table above. Kalshi removes a contract from its interface once it settles and Polymarket buries closed events, so this page is the copy that stays put. We also record our own snapshot once a day, independently, because a history published by the house is worth checking against one kept by somebody with no position in it.
