Recorded price path

This is a live Kalshi event contract. The price, 89 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 83.7% of the time, and the crowd is charging 89c. Based on 332 settled markets across all categories in the 80-89c 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). Buying this systematically has been a slow bleed, and the 1c 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 other curve it came from.

What history says about this price

Across our settled record, markets priced near 80–89¢ have gone on to settle YES 84% of the time (n=332). The price implies 89%, so historically this band has come in about 5 points lower than the sticker. That is history, not a forecast for this specific market. See the Truth Machine for the full curve.
