Check settlement rules before comparing contracts. Matched outcomes may settle differently. These venues also report end dates more than 48 hours apart; event identity does not mean the contracts close or settle together. These are stored prices; record update times do not certify live quotes. Differences exclude fees and available size.

Known rule differences between venues

Both settle on the official ceremony result or nominations announcement for the same edition.
Kalshi lists a 'Tie' outcome and resolves ties per its rules; Polymarket resolves ties per its own description. Nominee lists differ; only names on both venues are linked.

A shared identity alone does not make a price difference executable.
