"Whales" are bettors who move real money — when several of them back the same side on a game, that's a signal worth watching. We track them anonymously on Polymarket, plus Kalshi and DraftKings' own sharp-money splits, and rank each whale by how they've actually performed, not by how big their bet is. Click any player row for their full track record.
