What percentage of Polymarket wallets are farming?
Update, July 2026: the third edition of our data report re-scored an expanded universe of 2,017 active wallets. The current figures lead the answer below. Note that fee-adjusted edge and the farming inputs are both computed differently than they were in June — see the dated notes — so the June figures further down read as their own snapshot, not as one end of a trend.
About half. Across the 2,017 actively-traded Polymarket wallets under CopyGrade coverage, 47.8% carry a farming flag and 37.3% a high-confidence (severe) one. On the wallets actually topping Polymarket's leaderboards, it's worse: 59.8% flagged, 46.0% severe. Farming isn't a fringe problem on the high-volume end of the platform — it's closer to the norm.
What "farming" means here
Farming is a wallet built to profit from copiers rather than from the market. The pattern is familiar: build a clean-looking record quietly, attract followers, then exit into them. It hides from a profit ranking completely, because it's a behavioural pattern in the trade history, not a number in the PnL column. We flag it from the public trade tape using a taxonomy of specific signatures — iceberg accumulation, self-trade wash, decoy clusters, stealth merges, pump-and-dump, and copy-bait — each carrying a severity and a confidence so one unmistakable signal can veto a wallet while two borderline ones only warn.
| Farming level | Share of the 2,017 active wallets |
|---|---|
| Clean | 52% |
| Watch — emerging signals | 11% |
| Severe — high-confidence | 37% |
The dangerous overlap
The part that makes due diligence non-optional is where farming meets a good-looking record. A clean track record is exactly what a farmer builds — and a skilled one builds the most convincing version. Plenty of farming-flagged wallets also post a positive headline edge, which is precisely the profile that ranks well, reads as a great copy target, and is set up to turn its followers into exit liquidity. The leaderboard can't see any of it.
How to check a specific wallet
Before you copy anyone, look past the profit number:
- Read the farming check, not the PnL. A high raw return on a farmed wallet is the bait, not the signal.
- Demand a post-fee edge. What a copier keeps after fees, slippage, and latency is the number that matters.
- Check risk-adjusted return. A streak and a strategy share a headline; only one repeats.
The per-wallet Copy Verdict shows the farming evidence trail, the post-fee edge, and the risk-adjusted breakdown in one place. For the full distribution — and why the leaderboard is the dirtiest slice of all — see We scored the Polymarket leaderboard.
Figures are a June 2026 snapshot of wallets under CopyGrade coverage, scored from public Polymarket trade history and recomputed on every sync. The farming rate moves as coverage widens and the model is recalibrated in public.
