Polymarket's public leaderboard sorts wallets by raw dollar PnL over a window. That ranks lucky streaks, big bankrolls, and active farmers above patient, repeatable skill. A wallet at the top of the board may be running iceberg accumulation, decoy clusters, or stealth YES/NO merges — and the leaderboard won't tell you, because it wasn't built to.
Copy-trading bots solve a different problem: speed of execution. They will happily mirror any wallet you point them at, including the ones using their own copiers as exit liquidity. The diligence question — is this wallet's edge real, repeatable, and large enough to survive latency and fees? — is the question nobody else is answering. That is the only thing we do.
CopyGrade scores every covered Polymarket wallet 0–100 on whether it is worth copying right now. A five-factor model — edge authenticity, risk-adjusted return, drawdown resilience, consistency, and farming risk — produces a single verdict and the evidence behind it: forensic farming flags tied to specific on-chain trades, a category-edge breakdown, and a realistic-return number that already subtracts latency and fees. Analysis-only. We hand the verdict over; the trader chooses whether and how to act on it.
The fastest way to understand a product is to know what it refuses to do.
A copy-revenue share — taking a percentage of whatever copiers make on wallets we rate — would pay us more every time we said “copy” and nothing when we said “avoid”. Over time, that pressure shows up in the model. Borderline wallets drift toward green. Avoids become cautions. The product slowly becomes a sales channel for whichever wallets generate the most copy volume.
A flat monthly fee removes that pressure entirely. We are paid the same whether a wallet earns a strong-copy verdict or a hard avoid. That is the only structure under which calling an avoid is allowed to be the honest answer. The price is the integrity guarantee.
CopyGrade is not affiliated with Polymarket. We hold no partnership, no data agreement, and no shared ownership. We do not take referral fees or revenue share from any copy-trading execution provider, and we do not hold equity in any wallet, fund, or operator that appears in our coverage. The only commercial relationship in the picture is the one between us and the subscriber.
