Very few of Polymarket's profit leaders are worth copying: of the 191 wallets atop the boards at the October 2026 snapshot, 61.3% carry a farming flag and none clear the copyable bar. The leaderboard ranks by raw profit — the one number that says almost nothing about whether copying a wallet makes you money — so this page grades every name on it. First, the 10 wallets that currently pass our vetting bar; then this month's 30d profit board with each trader's verdict. The full breakdown is in the October 2026 data report and all our published numbers; the standalone, hourly-refreshed shortlist — with each wallet's realistic edge and observation span — lives at best Polymarket traders to copy.

For agents: the CopyGrade MCP server and the keyless read API grade any wallet on this board programmatically, no key required.
Most profit leaders don't clear our vetting bar — these wallets currently do: our model flags no farming risk, the CopyGrade Score sits in the Copy-candidate band or better, and each has traded within the last 30 days. A passing grade is CopyGrade's documented opinion as of the latest sync, not a guarantee — open a wallet's Copy Verdict before copying anyone.
Raw profit rewards account size, reckless sizing, and luck, and it's computed on the leader's own fills — zero fees, their timing. A copier pays taker fees in and out and eats slippage and latency. And farming — a wallet built to turn its copiers into exit liquidity — is invisible to a profit ranking, because it's a behavioural pattern in the trade history, not a number in the PnL column. The CopyGrade Score reads both. See how it's calculated, the farming signatures we check for, and how to run the full vetting checklist on any name below.
The 30-day profit leaderboard — the top 50 wallets by realised profit over the trailing month, each paired with its CopyGrade Score, verdict band and farming-risk level, refreshed hourly. It replaced the all-time board in July 2026 because that board surfaced wallets that had not traded in over a year, while every 30-day leader had traded within days. Per-category boards sit below the main standings.
Because a ranking by raw profit and volume rewards exactly the behaviours farming produces — manufactured volume, oversized swings, and positions built to be dumped on the copiers they attract. In the October 2026 snapshot, 61.3% of the 191 wallets atop Polymarket's boards carried a farming-risk flag, against 35% of the wider active population. A flag is CopyGrade's documented risk assessment from public trade history, not a statement of fact about any trader.
It is the wallets that currently clear CopyGrade's screening bar: no farming-risk flag from our model, a CopyGrade Score in the Copy-candidate band or better, and at least one trade in the last 30 days. It is a screen to start diligence from, recomputed hourly, and it is looser than the strict copyable test behind the Polymarket Copyability Index, which also requires a positive verdict, a positive realistic post-fee edge and enough recent trades. Open a wallet's Copy Verdict before copying anyone.
Yes. Each category — sports, crypto, economics and the rest — has its own graded board. Edge is category-specific, so a wallet that is sharp on one board is routinely a donor on another; the per-category boards surface specialists a global profit ranking buries. Every board links each wallet to its public Copy Verdict.

CopyGrade is independent, analysis-only due diligence — it never executes trades or holds funds. Standings are the public Polymarket leaderboard; the CopyGrade Score and verdict are computed from public Polymarket trade history and recomputed on each sync, and are CopyGrade's documented opinion, not a statement of fact about any trader. Not financial advice.
