AI-matched pair
A cross-venue market pair that an automated reviewer judged to be the same question, shown with the reviewer's confidence score.
Kalshi lists roughly 100,000 markets and Polymarket thousands more; finding the pairs that ask the identical question is a matching problem. ArbMonster's matcher proposes candidates from titles, dates and rules, has a language model judge equivalence, and only confirmed pairs are scanned. The confidence is displayed on every card because the user, not the model, is responsible for verifying the rules match.
