Check settlement rules before comparing contracts. Matched outcomes may settle differently. These are stored prices; record update times do not certify live quotes. Differences exclude fees and available size.
Known rule differences between venues
- Kalshi resolves on the acquirer announcing an agreement; Polymarket on an official announcement that the target will be acquired by or merged with the acquirer. A merger framed the other way round can split them.
A shared identity alone does not make a price difference executable.
