Related Concepts

• endogeneity — When the existence or visibility of a prediction market influences the very outcome it aims to forecast, undermining its reliability as a neutral signal. Particularly relevant in political and social markets where public price movements can shift behavior.
• 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.
• info finance — Using financial market mechanisms to elicit, aggregate, and trade on informational signals about future events.
• forecasting accuracy — Measuring how well predicted probabilities match actual outcome frequencies over many events.
• probability infrastructure — The concept of prediction market mechanisms as a general-purpose layer that embeds live probability signals into decision surfaces beyond trading, such as attention, credibility, and demand.
