This is a live Kalshi event contract. The price, 5 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.

KALSHI CHARGES

MARKETS LIKE THIS SETTLED AT

5¢

Contracts like this one have settled YES 4.8% of the time against a 6c price, which is close enough to fair that the 1c fee eats whatever is left. Based on 147 settled other markets in the 0-9c 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 0–9¢ have gone on to settle YES 6% of the time (n=1,004). That is history, not a forecast for this specific market. See the Truth Machine for the full curve.
