• nowcasting — Using prediction market prices as real-time proxies for economic indicators that are officially reported with a delay, such as inflation or employment figures. Enables faster decision-making by treating continuously updated market odds as a high-frequency data source.
• wisdom of crowds — The phenomenon where aggregated group estimates often outperform individual experts in forecasting accuracy.
• information aggregation — The process by which markets combine dispersed private knowledge into a single consensus price signal.
• insider trading — Trading on material non-public information (MNPI) obtained through a breach of a confidentiality duty or implied promise. In prediction markets, this arises when participants trade on privileged access to information about upcoming events, creating adverse selection for other traders.
