This is a live Kalshi event contract. The price, 3 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.

AFTER THE 1¢ FEE

Contracts like this one have settled YES only 6.5% of the time, and the crowd is charging 9c. Based on 92 settled other markets in the 0-9c band, priced about a day before their events. 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 0–9¢ have gone on to settle YES 9% of the time (n=479). The price implies 3%, so historically this band has come in about 6 points higher than the sticker. That is history, not a forecast for this specific market. See the Truth Machine for the full curve.
