Polymarket copy-trading, done properly

The theory of copying a Polymarket whale is easy. The practice is where most guides fall apart. Here is how the Polyterminus copy-trading engine actually works.

"Copy the whales" is one of those pieces of advice that sounds smart and turns out to be almost impossible without the right tooling. Here's the honest version.

The five hard problems

Which wallet is actually a whale? Big portfolio value doesn't mean skilled — it might mean "held one 60¢ bet that resolved YES." You need P&L, not portfolio value.
What is the wallet's style? Someone with 40 trades a day is a scalper — copying their tape gets you 40 trades a day too. Someone with 3 holdings and 0 recent trades is a conviction holder — you copy one trade a month.
What are they good at? A politics specialist has no edge on sports. You want to filter by vertical.
When do they enter? Reading a wallet's positions AFTER the market moved is worthless. You need low-latency signal on the ENTRY.
How much should you copy? Copying a $10M wallet's $50k position with your $500 balance breaks portfolio construction badly. You need proportional sizing.

What Polyterminus does

Leaderboard (top 120)

We fetch the top 35 markets by 24h volume from Polymarket, pull the top 15 holders of each, then enrich every wallet with: rolling 30-trade P&L, position count, portfolio value, dominant vertical, trader-type label (scalper / swing / holder / diversifier / specialist), and the 5 most recent trades. Cached for an hour so we're not hammering the data-api.

Filters that work

Vertical filters match on any exposure ≥ 20% (not just dominant ≥ 50%) — so a 30% crypto / 30% politics / 40% sports whale correctly appears under the Crypto chip. Combined with trader-type, activity, and sort options, you can quickly narrow 120 whales down to "the 8 crypto scalpers with recent trades > $5k."

Follow modes

Read-only: notifications when the whale opens a position. You decide whether to mirror.
Autopilot (Pro): proportional mirror based on your % allocation. Per-whale allowlist so you can follow "only crypto trades from wallet X".

Sanity ceilings

Even in autopilot, hard caps on: per-trade $ (defaults to your daily-loss-limit / 5), per-whale monthly spend, minimum ticket size (skips their sub-$10 dust trades).

What we don't promise

Copying whales won't beat holding index-like exposure to Polymarket volume. The best whales beat the average by picking their spots — copying them mechanically means also copying their bad picks. Use the leaderboard as an idea generator, not an autopilot for retirement.
