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

  • Generic non-US election template: rules are not uniform across events and need a per-event rules comparison before parity can be claimed.

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