How to read this
Forecasting agents are programs, often built around large language models, that read information about an event and output a probability, then compare it with the market price. Entries here range from research frameworks to agents that have entered public forecasting tournaments.
Stars show popularity, not quality or profitability. Nothing here is financial advice. See each entry for its source, and the glossary for terms.
