Research has long indicated that a small cohort of traders drives price movements in prediction markets, but new findings suggest an even smaller subgroup is accumulating the majority of the profits. A recent report by blockchain analytics firm Solidus Labs uncovered that profit distribution on Polymarket is heavily skewed, with fewer 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 gains, translating to around $8 million out of $16 million in profits. This discovery builds upon existing academic research, which found that about 3% of Polymarket traders are responsible for most price discovery.
The report highlights that this extreme concentration of wealth does not necessarily imply malfeasance, as some traders may simply possess greater sophistication, better capitalization, or faster access to information. However, it does suggest a profound structural disparity between a small, highly advantaged group and the broader participant base. According to the report, the traders capturing a disproportionate share of profits operate in a distinct league, leveraging significant advantages in terms of capital depth, infrastructure, and execution strategies.
The study also identifies signs of wash trading, with approximately 15% of volume in certain markets exhibiting patterns consistent with self-trading or economically neutral positions. This phenomenon, which has no equivalent in traditional finance, may be driven in part by incentive farming in anticipation of Polymarket's forthcoming POLY airdrop.
While the data itself is verifiable and on-chain, the report's framing should be considered in the context of Solidus' market surveillance sales pitch.
