WSJ: 0.1% of Polymarket accounts capture 67% of platform profits
A Wall Street Journal analysis found that 67% of profits on Polymarket flow to fewer than 1% of traders, with 0.1% of accounts capturing the full 67% concentration. A separate data analysis of 1.5 million Polymarket traders showed only 21% ever turned a profit, meaning roughly four in five lost money. A third study cited by the Financial Freedom Blog found 69% of Polymarket users lose money while the top 1% capture 76.5% of total profits. The findings were shared across Reddit and finance outlets including Yahoo Finance, with commenters attributing the low win rate to structural advantages held by sophisticated or well-connected participants.
Polymarket loses its retail-everyman positioning just as state attorneys general in Rhode Island, Minnesota, and Nevada are building fiscal and enforcement cases against prediction markets. The profitability concentration data gives prosecutors a consumer-harm narrative to pair with the AGA's tax-revenue claims.
Adds the Wall Street Journal to Bloomberg and the AGA in a three-sided press offensive against prediction market profitability claims, with each outlet attacking from a different vector: user outcomes, tax avoidance, and data opacity.
