KALSHI CHARGES

34¢

MARKETS LIKE THIS SETTLED AT

32¢

Contracts like this one have settled YES 32.1% of the time against a 34c price, which is close enough to fair that the 2c fee eats whatever is left. Based on 187 settled markets across all categories in the 30-39c band (we do not yet hold enough other history to price this by category, so this is the market-wide curve and is weaker evidence).

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 30–39¢ have gone on to settle YES 32% of the time (n=187). That is history, not a forecast for this specific market. See the Truth Machine for the full curve.
