Recorded price path

This is a live Kalshi event contract. The price, 29 cents, is the market’s implied probability of YES. Whether that number is well-calibrated is its own question: our Truth Machine measures how often markets at each price level actually settle YES. Confirm live prices on Kalshi before trading.

Contracts like this one have settled YES only 24.4% of the time, and the crowd is charging 29c. Based on 987 settled sports markets in the 20-29c band, priced about a day before their events. Buying this systematically has been a slow bleed, and the 2c fee makes it worse.

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 sports 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=1,279). The price implies 29%, so historically this band has come in about 4 points lower than the sticker. That is history, not a forecast for this specific market. See the Truth Machine for the full curve.
