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
- Both resolve Yes on a missed Treasury note/bond/bill payment or a major rating agency default designation; Polymarket only counts events after its creation date (e.g. Nov 5, 2025).
