This is a live Kalshi event contract. The price, 90 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

AFTER THE 1¢ FEE

Contracts like this one have settled YES 92.0% of the time, and the crowd is charging 90c. Based on 721 settled markets across all categories in the 90-99c band (we do not yet hold enough economics history to price this by category, so this is the market-wide curve and is weaker evidence). After the 1c taker fee, that leaves about 1c of edge per contract, if this market behaves like the ones we measured.

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 economics curve it came from.
