Our Story
The growth of decentralized prediction markets and regulated event contract platforms has revolutionized how the world processes information. Events across global politics, macroeconomics, technology, science, and sports are now priced in real-time by participants worldwide.
However, navigating this expanding landscape can be challenging. Active traders, quantitative modelers, and prediction enthusiasts need reliable resources to manage portfolios, calculate cross-platform arbitrage opportunities, build alert webhooks, and audit on-chain volume.
PredictionDirectory started as a simple resource collection and has since evolved into a comprehensive repository. We vet and organize tools by functional categories—such as Analytics, Developer Tools, Portfolio Tracking, and Alerts—to help you build your trading stack with confidence.
