Research has shown that a tiny fraction of traders is driving the majority of profits on Polymarket, with less than 1% of wallets accounting for roughly half of all gains. A report by blockchain analytics firm Solidus Labs found that across Polymarket's politics markets, a mere 0.55% of profitable maker wallets and 0.26% of winning taker wallets captured around 50% of gains, translating to approximately $8 million in profits. This data supports previous findings that a small minority of traders influences price movements, with around 3% of Polymarket traders driving most price discovery. The significant imbalance in profit distribution suggests a structural divide between a small group of sophisticated traders and the broader base of participants, with the former operating with substantial advantages.
The report also identified signs of wash trading, accounting for around 15% of volume in some markets, which may be attributed to incentive farming or manipulation. While the data highlights the need for surveillance infrastructure, it is essential to consider the source, as Solidus Labs sells a surveillance platform and has a vested interest in promoting its product.
