Your call

The market says 94%. 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 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.
