Polymarket's Brutal Math: 0.1% of Users Grab 67% of Profits
A Wall Street Journal analysis of 1.6M Polymarket accounts reveals prediction markets are a playground for algorithmic whales.
Prediction markets love to sell the dream of democratized forecasting. The reality? It's a shark tank.
A Wall Street Journal analysis of 1.6 million Polymarket accounts dating back to November 2022 found that just 0.1% of users capture a staggering 67% of all profits. The pattern is clear: the highest-frequency traders consistently come out on top.
The winners aren't casual bettors with good instincts. They're predominantly professionals running data-driven algorithmic trading strategies across platforms like Polymarket and Kalshi. Think quantitative hedge fund tactics applied to event contracts.
For the vast majority of users, prediction markets function less like wisdom-of-the-crowds tools and more like casinos where the house edge belongs to whoever has the best bots. The numbers don't lie — retail participants are largely funding the pros.
