A small cohort of traders appears to be controlling the prediction markets, but an even smaller group is accumulating the majority of the profits. According to a recent report by blockchain analytics firm Solidus Labs, the concentration of profits on Polymarket is staggering, with less than 1% of wallets capturing approximately half of all gains in key markets. Between December 2025 and February 2026, a mere 0.55% of profitable maker wallets and 0.26% of winning taker wallets accounted for roughly 50% of the gains, translating to around $8 million out of $16 million in profits.
This data reinforces the notion that a small minority drives price movements, while an even smaller minority reaps the financial benefits. The disparity highlights a crucial point: concentration does not necessarily imply wrongdoing, as some traders may simply be more sophisticated, better capitalized, or quicker to respond to information. However, the report suggests that the scale of the imbalance indicates a structural divide between a small group with significant advantages and the broader base of participants. The study also identifies signs of wash trading, with approximately 15% of volume in some markets exhibiting patterns consistent with self-trading or economically neutral positions.
This phenomenon, which has no equivalent in traditional finance, may be driven by incentive farming rather than pure manipulation, particularly in anticipation of Polymarket's forthcoming POLY airdrop. While the data is verifiable, the report's framing should be considered in the context of Solidus' sales pitch for its surveillance platform, HALO.
