Known rule differences between venues
- Both settle on the official league/organizer result for the named season; Kalshi's season is the ticker edition (KXNBA-27 = 2026-27) and Polymarket's is stated in the title or slug.
- Season cancelled or not completed: Kalshi resolves per its rules (typically a fair price); Polymarket resolves to 'Other' or 50-50 depending on the event.
- Polymarket lists placeholders ('Other', 'Team A') and closes eliminated outcomes early; only live named outcomes are linked.
A shared identity alone does not make a price difference executable.
