Yale Study Finds 3% of Polymarket Accounts Earned 27% of Dollar Profits

A Yale study found that roughly 3% of Polymarket accounts collected 27% of all dollar profits. According to NS3.AI, the working paper reviewed two years of Polymarket trades across 1.72 million accounts and 210,322 markets. Yale economist Theis Jensen said he expects the share of skilled traders to fall below 1% as competition increases.
