Key Insights

  • Approximately 25% of Polymarket trades are "wash trades," where the same contract is bought and sold to create fake trading volume.
  • Researchers flagged nearly 15% of wallets (1.26 million) on the platform as participating in these artificial transactions.
  • At its peak in December 2024, an estimated 60% of Polymarket's trading volume was attributable to phony orders.
  • The use of cryptocurrency stablecoins may facilitate these types of transactions.

In-Depth Analysis

Polymarket allows users to trade "contracts" based on the probability of real-world events. The study analyzed three years of trading activity and identified "wash trades" as a significant issue. These trades involve buying and selling the same contract to create artificial volume. Researchers developed an algorithm to identify accounts engaging in these practices, revealing networks of traders seemingly involved in wash trades.

While the study does not accuse Polymarket of directly participating in these manipulations, it suggests that the platform's use of cryptocurrency could make such activities easier to execute. Polymarket has also been observed using social media to generate trading volume, which, while not necessarily manipulative, is aggressive.
