How to read this page
Prices are Kalshi’s: what a contract paying $1 if that outcome happens costs, read as a probability. A dash is a contract nobody has traded and whose book is too wide to read.
The card is ordered from the main event down, by when the exchange expects each result. Results come from each market’s grading. Kalshi’s method-of-victory markets began in January 2026, so the method here comes from the fight data.
Ended is the round and the time into it, from the fight data, shown where that data names the same winner as the market.
At start is the winner’s price at the last trade before the card’s first scheduled bout. Upset marks a winner the market priced lower then.
