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 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.
