Volume for the venues we measure ourselves, pulled daily from each venue's own endpoint and stored in our warehouse. Notional throughout, so the rows add up.
179 funding rounds and acquisitions logged, each with its source and a confidence grade. $7.8B in disclosed capital so far.
The app you trade on is rarely the exchange, and the exchange is not always the clearing house. We map every layer, so you can see who actually holds the risk.
The contracts that have traded the most, from Kalshi and Polymarket side by side, refreshed hourly.

Monthly volume on US-regulated prediction markets, Oct 2025 – Sep 2026, read from each venue’s own published files and stored in our warehouse.
Prediction markets data is siloed. Every venue reports on its own page, in its own unit, on its own schedule. We bring it into one data layer, source first, so the numbers finally add up.
Every figure carries its basis, its source and its age, without a click. Notional and handle never share an axis, and a number from a venue's own endpoint is never quietly blended with one from an aggregator.
Bots and agents already trade these venues. We are opening The Prediction to them through a REST API and an MCP server, so any agent, Claude included, can ask for a venue’s volume, a company’s backers or who clears what, and get the answer with its basis and source attached.
See how your venue compares with its competitors: volume, fees, clearing and who owns each layer of the stack.
Every round in the sector, 179 and counting, with the investors behind it and where the money is going next.
Figures you can cite, each with its basis, its source and its date. No aggregator numbers passed off as a venue's own.
Cross-venue volume, open interest and fees on one basis, with the working shown. Built to be checked, not screenshotted.
