KALSHI CHARGES

18¢

MARKETS LIKE THIS SETTLED AT

17¢

Contracts like this one have settled YES 16.7% of the time against a 18c price, which is close enough to fair that the 2c fee eats whatever is left. Based on 54 settled other markets in the 10-19c band, priced about a day before their events.

This is what this kind of contract has been worth, not a forecast for this one: a band average does not know what is happening in the news. See the Fair Value Board for every market scored this way, or the other curve it came from.

What history says about this price

Across our settled record, markets priced near 20–29¢ have gone on to settle YES 25% of the time (n=314). That is history, not a forecast for this specific market. See the Truth Machine for the full curve.
