Galaxy Research finds 69.2% of retail Polymarket traders lost money
Galaxy Research found that 69.2% of retail traders on Polymarket finished in the red. The study also named Crypto.com, ProphetX, and Fanatics as other platforms in the space. Galaxy said nothing in its report undermines the case for prediction markets as 'truth machines.' The article body provides no further details on methodology, sample size, or time period covered. Both sources published the finding on October 2, 2026.
Bernstein's $10 trillion prediction-market forecast depends on retail participation scaling smoothly into revenue. Galaxy's finding that most Polymarket retail traders lose money threatens that assumption. Equity analysts valuing Robinhood and Coinbase on event-contract growth must now model higher churn and lower lifetime value than consensus assumes. The $339 million aggregate loss figure gives shorts a concrete talking point against premium multiples.
If retail traders recognize the platform as a negative-sum venue, acquisition costs will rise and volume growth will slow. Polymarket's lead in political event volume becomes less valuable if it cannot retain users through losing streaks. The first operator to publish tools that improve retail win rates would flip the narrative and capture the traders competitors bleed.
