Recent findings indicate that a minuscule group of traders is disproportionately capturing the majority of profits on Polymarket, with less than 1% of wallets accounting for roughly half of all gains in key markets. According to a report by blockchain analytics firm Solidus Labs, this extreme profit concentration is evident across Polymarket's politics markets, where 0.55% of profitable maker wallets and 0.26% of winning taker wallets collectively captured around 50% of gains between December 2025 and February 2026.
This translates to approximately $8 million in profits for each of these tiny cohorts, out of a total of around $16 million. The research builds upon existing academic work, which suggests that a small minority of traders drives most price discovery, with around 3% of Polymarket traders responsible for this phenomenon.
The report highlights that this concentration of profits does not necessarily imply wrongdoing, but rather that some traders possess significant advantages, including greater sophistication, better capitalization, and faster access to information. However, the scale of the imbalance raises concerns about a structural divide between a small elite group and the broader base of participants. The report also notes signs of wash trading, with around 15% of volume in some markets exhibiting patterns consistent with self-trading or economically neutral positions.
This phenomenon is unique to binary prediction markets, where outcome tokens sum to approximately $1.00, allowing traders to engage in economically delta-neutral trades. While some of this volume may be attributed to incentive farming rather than pure manipulation, it is essential to approach these findings with a critical eye, considering the firm's vested interest in promoting its surveillance platform.
