the public record

We disagree with the market in public — and get graded on it.

Polypredict puts its own price-blind probability on every live Polymarket market, publishes the disagreement with an uncertainty range and a per-jurisdiction legality read, and scores every call when reality answers. Often wrong, never advice — and never an order placed.

the scanner

Forecast blind. Publish. Get graded.

Four moves, every market, every refresh. The price enters exactly once — after the forecast is locked, never before.

  1. 01

    Blind to the price

    The forecaster never sees the market price. When we disagree with the crowd, it's a real opinion — not an echo of the number we're graded against.

  2. 02

    A probability, with its uncertainty

    Every market gets a calibrated estimate and a credible interval — wide when we don't know. Never false precision.

  3. 03

    Legality, per jurisdiction

    Your jurisdiction × the bet's category, with a cited source. A sports bet can be illegal where an economics one is fine — every tile says which.

  4. 04

    Graded on resolution

    When the market resolves, the call is scored — Brier, log-loss — and posted. Hits and misses alike. Nothing is quietly deleted.

the record

Scored in the open, or it doesn't count.

Every forecast is timestamped before resolution and scored after — against the outcome, and against the market price it never saw.

beats the price it was blind to

The fine print, up front: edge is unproven until the forward record proves it, P&L is midpoint-optimistic, and a short record is a weak verdict. We publish anyway — misses stay on the board.

by design

What it will never do.

No execution, ever

Polypredict never places an order, never touches funds, never holds keys. The execution path ships OFF — read-only is the design, not a setting.

No advice

Model opinions with error bars, not recommendations. The per-jurisdiction legality read is informational and cited — never a green light. Not financial, legal, tax, or gambling advice.

No hiding the misses

The model is often wrong. Every graded miss stays on the public board next to the hits — that's the entire point of grading in the open.

one kernel · three horizons

Polypredict is the proof leg of a bigger machine.

One forecasting kernel — calibrated, blind, graded — pointed at three futures. This is where it earns the right to be believed.

Predictive

invite-only

The kernel, pointed at your company

The same calibrated forecasting engine, put to work on the decisions a company bets on — demand, churn, launches — each one scored when the outcome lands.
