Public accuracy ledger · append-only

The receipts.

We publish our fair value for a market before it resolves — timestamped and hash-chained, so we physically can't move the number after the outcome is known. No cherry-picking. Grade us on the record.

Why this page exists

Anyone can claim their model is sharp after the fact. PolyEdge instead writes down its number in advance and locks it. When each market settles, you'll see whether our fair value beat the venue's closing price (closing-line value) and how well-calibrated we were. Until then, every row below is a promise on the clock.

The ledger is an append-only file where every entry's fingerprint is sha256(previous_hash + entry). Change any past number and every fingerprint after it breaks — the tampering is obvious. Nothing here can be quietly rewritten.

We grade the price, never the pick. Prediction markets are risky; nothing here is financial advice.
Fair value is our cross-venue, de-vigged consensus at the moment shown — not a prediction of the outcome.
