PredictionToolkitWhat is Based?
Choose the view that fits the research task: compare market metrics in a list, scan Yes/No outcome cards or organize a session around event dates in Calendar. Filters narrow the selection by status, volume, liquidity and date. A trader ranking can then lead into a portfolio page where open exposure and closed-position performance provide different context.
Prediction trading is documented for the web app and iOS and Android mobile apps. Keep that product separate from Based’s Hyperliquid, spot and perpetual offerings: their leverage and fee tiers do not automatically apply to prediction contracts. The documented Telegram bot focuses on Hyperliquid rather than establishing another prediction-trading surface.

Workflows with Based
Plan around an event date
Open Calendar, select a date and narrow the category and liquidity range. Read the exact market question before using its Yes/No entry controls.
Compare execution context
Use the market list to compare volume, spread-related context and closing time, then open the chosen event’s order book before placing an order.
Look behind a trader rank
Open a ranked trader’s portfolio and compare current exposure with the performance of closed positions rather than treating the ranking as a complete record.
