How the contract was worded
Kalshi's rules for the Milwaukee market read: "If Milwaukee wins the 2026 Pro Baseball Championship, then the market resolves to Yes." Every other team had the same wording with its own name, so the market was one Yes or No contract per team, not one ranked list. Kalshi closed the market at 03:14 UTC on October 29, 2026, and settled it on the result reported by its named sources.
What a settled champion market teaches
A champion market only asks one thing: who wins. It doesn't depend on the score of the final game, the length of the series or any player award. Once the last game is over and the named sources report the champion, there is nothing left to decide. That is why season-long champion markets usually settle cleanly, while race or award markets with more conditions can take longer.
