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 settle on the Billboard chart dated the named week. Polymarket labels mix 'Album - Artist' and 'Artist - Album'; a label is linked only when exactly one reading matches a Kalshi title.

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