Milwaukee's World Series odds on Polymarket went from 17% when the NLDS opened to 64% after Game 4. Chourio's card climbed with them.

Misiorowski's summer hype has already come out of his price. What's left is a pitcher with a 1.80 ERA who started the opener of both playoff series. A PSA 10 at around $265 USD sits about $65 USD under its August price. If he gets the ball in the Series, a big start could take it back toward that mark, while a bad one starts from a lower price than August buyers paid.

A Chourio PSA 10 bought around $40 USD this summer is now selling near $80 USD. The card never held above about $50 USD a month before October. His 3-for-19 NLCS says this price is riding the Brewers rather than his bat.
