Research has shown that a tiny fraction of traders on Polymarket are reaping significant financial rewards, 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, between December 2025 and February 2026, a mere 0.55% of profitable maker wallets and 0.26% of winning taker wallets captured around 50% of the profits, totaling approximately $8 million out of $16 million.
This disparity highlights the existence of a structural divide between a small group of sophisticated traders 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. While the data suggests a need for market surveillance, it is essential to consider the source, as Solidus Labs sells surveillance platforms and may have a vested interest in highlighting the need for such infrastructure.
