A recent study reveals that just 3% of traders are responsible for the majority of price accuracy in prediction markets, challenging the notion that collective wisdom drives these platforms. Analyzing 1.72 million accounts and $13.76 billion in trading volume on Polymarket from 2023 to 2025, researchers found that only a small group of informed traders consistently outperformed chance, while the remaining 97% largely contributed to liquidity without significant gains.
This finding has important implications for market participants, as it suggests that the effectiveness of prediction markets hinges on the skill of a select few rather than broad participation. The study highlights that skilled traders react swiftly to new information, enhancing price discovery, especially in critical moments like earnings announcements or economic data releases. Conversely, the majority of traders often find themselves on the losing end, raising questions about the sustainability of their strategies.
For market professionals, the key takeaway is to recognize the value of informed trading in prediction markets. Understanding the dynamics of this small, skilled group can provide insights into market movements and improve trading strategies, particularly in environments where information asymmetry exists.
