Yale study reveals 3% of Polymarket traders secure 27% of total profits

A Yale University study indicates that approximately 3% of Polymarket accounts generated 27% of the platform's total dollar profits. Researchers suggest that while a small group of skilled traders currently dominates, increasing competition and institutional participation are narrowing the edge for specialists. The study, which analyzed 1.72 million accounts, notes that more efficient pricing benefits all participants by reducing the likelihood of poor bets.
