Why Polyforecast

More Than a Prediction. A Full Research Brief.

Every report is structured for clarity, grounded in evidence, and graded after the fact.

  • Cited Evidence, Not Opinions

    Every forecast links to the primary sources it drew from. Verify any claim yourself.

  • Public Accountability

    When markets resolve, forecasts are graded win or loss and published. No deletions, no edits. Standard sports and esports match markets grade from a snapshot taken at least 60 minutes before close, while season-long outrights can still update until settlement.

  • Divergence Analysis

    See where our model’s probability differs from the live market price and understand why.

  • Invalidation Conditions

    Every report lists specific events that would change the forecast. Know when the thesis breaks.

Resolved markets without a completed model forecast are excluded from this board. Baseline fallbacks mirror market pricing and are not counted here. For standard sports and esports match and prop markets, grading uses the latest completed model snapshot from at least 60 minutes before market end. Season-long outright markets stay updateable until close.

FAQ

Common questions

Is there a free plan?

Yes. Free accounts can browse all markets, view live prices and charts, access the public scoreboard, and read full reports for settled markets. Active market AI forecasts stay locked until you upgrade to a paid plan.

Can I cancel anytime?

Yes. You can cancel your subscription at any time from your account page. Your access continues until the end of the current billing period. Refunds are not provided for partial billing periods as the service delivers informational content immediately upon access.

What's the difference between Pro and Trader?

Pro is the core self-serve plan for individual users and supports up to 20 monitored markets. Trader raises that limit to 100 and gets faster queue priority plus upcoming team workflow features.

Is this financial advice?

No. Polyforecast provides informational forecasting reports only. It does not provide trading, investment, or legal advice.

How is accuracy tracked?

Each completed model forecast is timestamped at publication. Once a market resolves, that completed model call is compared to the resolved result and logged publicly. Baseline fallback snapshots that simply mirror market pricing are not counted in the public record. Standard sports and esports match or prop markets use the latest completed model snapshot from at least 60 minutes before market end, while season-long outrights stay updateable until close.

How often do forecasts update?

Pro and Trader coverage refreshes throughout the day on demand and schedule. If a model cycle falls back to baseline, the report is explicitly labeled.

What sources are used?

Reports cite primary public sources such as official releases, market data pages, and institutional publications.

Why might a forecast match market pricing?

Some forecasts confirm the existing market baseline. In those cases the report explains why no meaningful divergence was detected.
