What counts

The market resolves to Tampa Bay Rays if they win the game and Cleveland Guardians if they win. It stays open if the game is postponed but closes immediately if it is canceled with no make-up game or ends in a tie. Readers often mistake the original October 17 date for the deadline, but the official start time is now October 18 at 5:00 PM ET.

Written from Polymarket's resolution rules by the same model that writes our headlines. The rules on Polymarket are what decides it.

Outcomes

  • Tampa Bay Rays 55%
  • Cleveland Guardians 46%
