The overround on this market

Add up what it costs to back every outcome here and Kalshi's board comes to 108%. A fair book sums to 100. The excess is the house's cut, paid by whoever trades, and it is the reason the same opinion costs different amounts in different places. That number is what this site is named after.

Your call

The market says 54%. 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 8 July 2026, 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.

Over this window Vivek Ramaswamy and Jon Husted win went from 45.5 to 23.5, a move of 22 points away from happening.

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.
