Your call

The market says 23%. 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.

The record

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.

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.
