Every Polymarket wallet gets a single 0–100 Copy Score — a verdict on how copyable it is right now. The score is the weighted blend of five factors, each scored 0–100 and recomputed on each sync. A severe Farming Risk finding can veto an otherwise-strong score.
Each finding is weighted by severity (how bad if real) and confidence(how far past its threshold the pattern sits); the level rolls up that weighted total, so one unmistakable signature can veto while two borderline ones may only warn. Each detector's definition and exact threshold lives on the farming detection page.
What the metric is: for each snapshot, a simulated copier mirrors only the positions the wallet opens after that moment (buy-time windowed), and the outcome is the realized return of the round-trips that close within the horizon, net of modeled fees. What it isn't: the realized figure counts only round-trips that close inside the horizon, which understates slow, patient strategies. Beside it we now show a mark-to-marketestimate that also marks the positions still open at the horizon's end to current price — it exists for recently-matured cohorts and reads “—” for older windows (marking a long-closed window to today's prices would be a fiction, not a measurement). Dormant windows — where the wallet did nothing for a copier to mirror — are excluded, so the table is not diluted by no-observation rows. Only windows the sync observed end-to-end count, and a band is published only once it holds at least 30 outcomes.

Until these tables show a persistent positive relationship, the Copy Score remains a documented v1 heuristic — our assessment methodology, not a proven predictor. Aggregates only; no individual wallet's outcome is published. Last computed Jul 12, 2026 · refreshed daily.
These are the current heuristic v1 priors — graded against real wallet outcomes in the track record above, so the numbers can change as the model is recalibrated. CopyGrade is analysis-only — it never executes trades or holds funds. Not financial advice.
