Api Endpoint

SiteCheck

The largest position holders of each outcome of one Polymarket market (condition id from /api/pm/event): wallet, public name if the holder shows one, shares held, and each holder's share of the listed top holders' total. Polymarket's Data API lists the top holders only, so totals cover those wallets, not the whole outcome supply. Up to 50 per outcome. Information only, not financial advice.
