The intelligence layer
for prediction markets
The leading prediction market exchanges are producing the most honest real-time forecasts on earth. Predictboard is the single place to read, compare, and understand them — without opening multiple tabs, normalising conflicting data formats, or missing a price movement that matters.
“The crowd’s best guess about the future shouldn’t require five browser tabs to read.”
For most of prediction markets' history, sophisticated forecasting tools were either locked inside academic institutions or scattered across platforms that didn't talk to each other. The CFTC's landmark recognition of Kalshi in 2024, followed by Polymarket's regulated US expansion in 2025, changed the category entirely. These are now serious federal financial instruments — tracking everything from Fed rate decisions to World Cup outcomes — with real money and real forecasting accuracy behind them.
But the tooling never caught up. Traders were manually checking multiple platforms. Journalists were quoting stale screenshots. Researchers had no unified, normalised data source. Predictboard was built to close that gap.
We're an exchange-agnostic intelligence layer — not a trading platform, not an exchange with a thumb on the scale. Every probability displayed here is sourced directly from exchange APIs, normalised to a consistent format, and refreshed every two minutes. No editorialising. No interpolation. No invented numbers.
What Predictboard actually does
Stop switching tabs. Start trading smarter.
If you trade across prediction market exchanges, you already know the problem: prices diverge, opportunities appear and vanish in minutes, and no single platform shows you the full picture. Predictboard puts every exchange side by side so price differences are impossible to miss.
The Movers page surfaces the biggest probability shifts in the last 24 hours. Event playbooks give you structured context before the Fed meeting, the World Cup, or election night.

Prediction markets are increasingly used by major publications as a real-time barometer of public expectation — alongside or instead of polls. Predictboard makes those numbers easy to access, accurate to cite, and straightforward to embed.
Every probability is sourced directly from CFTC-regulated exchanges, timestamped, and documented. Our methodology is published and transparent. Embeddable probability cards let you drop a live market number into any article without writing code.
For academic researchers, we offer historical data exports, API access, and direct partnerships for ongoing data needs.

Predictboard's users are traders, analysts, journalists, and researchers — people who consume financial data professionally and act on it. This isn't a general-interest finance audience. It's a concentrated group of high-intent users who arrived specifically to track real-money probability markets.
Sponsorship inventory is deliberately curated to maintain editorial credibility. Partnership formats include newsletter sponsorships, sponsored market pages, and co-branded event coverage during major political and sporting events.
How we calculate what you see
Regulated exchanges only
We aggregate exclusively from regulated prediction market exchanges. Current live sources:
The first CFTC-designated contract market for event contracts in the US, following its landmark 2024 court victory establishing prediction market contracts as regulated financial derivatives. Settles in USD via bank transfer.
The world's largest prediction market by volume, now CFTC-regulated following its QCEX acquisition in 2025. Backed by ICE (NYSE parent) with a $9B valuation. Operates on Polygon blockchain, settles in USDC stablecoin.
What we are. What we’re not.
Three things we won’t trade away
Every probability on Predictboard is sourced directly from the exchange API. We never estimate, interpolate, or editorially adjust a price. If data is delayed, we say so. We would rather display a timestamp than display a guess.
Prediction markets are not perfect forecasting instruments. Thin markets are flagged. Our full methodology is published here and kept current. When markets have been wrong in notable ways, we document that too — because calibration data is only useful if it includes the misses.
Every guide, comparison, playbook, and glossary entry on this site is and will remain free. A more informed trader improves the whole ecosystem. We won't paywall the content that makes people smarter.
We read every email
We provide real-time probability data to journalists, broadcasters, and academic researchers. Embeddable widgets, API feeds, and white-label data packages are available. Reach out to discuss what you need — we're flexible on format.
