Recorded price path

This is a live Kalshi event contract. The price, 1 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.

What history says about this price

Across our settled record, markets priced near 0–9¢ have gone on to settle YES 8% of the time (n=744).
