CopyGrade
Methodology

How the CopyGrade Score is built.

Every Polymarket wallet gets a single 0–100 CopyGrade 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.

The model

Five factors, and how they're weighted

Edge Authenticity
28%
Separates genuine skill from luck and variance. A wallet with a short, lucky streak scores low here even if its PnL looks strong.
Risk-Adjusted Return
22%
A Sharpe-style measure of return per unit of risk taken — not raw PnL, which rewards reckless sizing.
Drawdown Resilience
18%
How the wallet behaves in losing streaks: depth of drawdowns and how quickly it recovers.
Consistency / Regime Stability
16%
Whether the edge holds across different market regimes and time windows, or only existed in one favourable stretch.
Farming Risk
16%
A forensic check for behaviour that turns copiers into exit liquidity — iceberg accumulation, decoy clusters, stealth YES/NO merges, and self-trade washing.
Total weight
100%
The veto

How farming caps the score

—
Clean
No cap
No detector tripped — the score reflects the full five-factor blend above.
•
Watch
Capped at 64
A moderate-confidence finding (or a couple of borderline ones). The wallet can never read as a strong copy candidate until it clears.
••
Severe
Capped at 30
A high-confidence signature, or several moderate ones by weighted severity. The score is vetoed to the Avoid band, however good the headline PnL.

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.

The caps

Three more ceilings a candidate must clear

Activity gate — trades
Capped at 64
Fewer than 20 trades in the trailing window
Too little recent history to judge as a candidate. A five-trade wallet cannot read as a strong copy candidate however clean its numbers.
Activity gate — record length
Capped at 64
A record spanning fewer than 30 days from first to last fill
A record can carry plenty of fills and still be days old. Measured 2026-09-01: top-band wallets with a record shorter than 30 days produced a positive 30-day forward return in about 3% of windows, against 19–31% for longer records.
Edge floor
Capped at 64
Realistic edge below 1% after fees and latency
Copying a no-edge wallet nets about nothing however clean its risk metrics — the great-Sharpe, tiny-consistent-wins, zero-net pattern.

Together with the farming veto these are the four caps on the blended score: a wallet must clear all of them to read as a copy candidate. Volume is not one of them — an open limitation. A minimum-stake floor was measured on 2026-09-01 and parked for re-measurement rather than built: small books mostly went quiet rather than losing, and their hit rate was not monotone in volume. Nothing in the blend is dollar-weighted, so a statistically clean wallet with a few hundred dollars of tracked volume can reach the top band.

Track record: scores vs. realized outcomes

Every score snapshot is graded later against what a simulated copier would actually have realized over the following weeks. These tables are computed live from that grading — they are the model's report card, published whichever way they point.

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-market estimate 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 CopyGrade Score remains a documented v1 heuristic — our assessment methodology, not a proven predictor. Aggregates only; no individual wallet's outcome is published. Last computed Oct 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.
