What percentage of Polymarket wallets are farming?
Update, October 2026: the fourth edition of our data report re-scored 11,721 active wallets; the current figures lead the answer below. The blended flag rate fell from 47.8% to 35.0%, but the same wallets covered in July are flagged at exactly 47.8% again — the drop is who we added, and half of the new wallets are records too thin for the detectors to read. Among wallets with enough recent history to judge, the rate is 55%.
About a third — and more than half of the wallets worth judging. Across the 11,721 actively-traded Polymarket wallets under CopyGrade coverage, 35.0% carry a farming flag and 24.2% a high-confidence (severe) one. Restrict that to the 5,636 wallets with at least 20 trades in the last 90 days — the ones with enough history to copy at all — and it is 55.2%. On the wallets actually topping Polymarket's leaderboards, it is worse still: 61.3% flagged, 44.5% 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 11,721 active wallets | Share of the 5,636 with 20+ trades in 90 days |
|---|---|---|
| Clean | 65% | 45% |
| Watch — emerging signals | 11% | — |
| Severe — high-confidence | 24% | — |
| Flagged (watch + severe) | 35% | 55% |
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.
