Research from Solidus Labs has uncovered a striking trend in Polymarket's prediction markets, where a minuscule group of traders is reaping the majority of the rewards. This phenomenon is evident in the platform's politics markets, where less than 1% of profitable wallets have amassed approximately half of the total gains between December 2025 and February 2026. The report notes that 0.55% of successful maker wallets and 0.26% of winning taker wallets have each accumulated around $8 million out of $16 million in profits.
These findings corroborate existing academic research, which suggests that a small minority of traders drives price movements in the market. The disparity between this group and the broader user base is stark, with the report attributing the imbalance to factors such as superior capitalization, infrastructure, and execution strategies. Furthermore, the study identifies signs of wash trading, accounting for around 15% of volume in certain markets, which may be indicative of self-trading or economically neutral positions. While the data is verifiable, it is essential to consider the context, as the firm behind the report, Solidus, offers market surveillance services, including the HALO platform, which is being deployed on Kalshi, a competitor to Polymarket.
