How to track a Polymarket whale

If you've identified a Polymarket wallet worth following — either because you're copying them, researching them, or trying to fade them — CrowdIntel gives you three ways to stay current.

Option 1 — Follow the wallet (fastest)

From any wallet dossier page, click the Follow button in the header. This adds the wallet to your watchlist and makes its trades appear in your feed.

What you get:

• The wallet's trades surface in your timeline within ~30 seconds of the on-chain confirmation.
• The wallet bookmarked — one click from your sidebar.

What you do not get: messages. Following is a discovery action and subscribes you to nothing. Push delivery is opt-in per channel, and you turn it on separately — see Alerts and delivery.

Option 2 — Add to a list (organised)

If you're tracking multiple wallets around a theme — a political-betting cluster, a crypto sharp group, a competitor in a category — lists let you group them.

1. Go to /lists. Create a new list (name + optional icon/color).
2. Visit each wallet's dossier, click Add to list, select your list.
3. Open your list page to see aggregate stats and combined timeline across all wallets.

Lists are useful because the sum of a group's behaviour often tells you more than any individual wallet.

Option 3 — Turn on a channel

Link Telegram, Discord or a webhook in Settings, then enable the channel for the wallets you want it for. Nothing is delivered until you do — linking a channel and following a wallet are two separate decisions, and neither implies the other.

The fastest way to set a sane policy across a long watchlist is the alert profile bar on /wallets: pick a preset and it shows the per-day volume it would actually deliver across your real follow set before you apply it. Per-wallet rules still override it. Full detail in Alerts and delivery.

What to watch for on a tracked wallet

Once you have a wallet watchlisted, the questions to keep asking as it trades:

New entries

• Size — is this trade in line with the wallet's typical bet size, or a notable deviation?
• Timing — did the trade land before, during, or after a known news moment in the category?
• Odds at entry — did the wallet enter at a cheap price (high odds against the outcome) or a short price (near-certain)?

New exits

Whales exit for many reasons: they want cash, they want to rebalance, they're running a hedge, or they've lost conviction. Exits are harder to read than entries. The rule of thumb: entries are signal, exits are noise unless they're repeated and consistent.

Consistency check

Every few weeks, revisit the dossier and ask whether the wallet's skill statistics have held up — not its win rate. The numbers that answer the question are the EV lower bound and the q-value, because both move when a run of results stops being distinguishable from luck. A win rate that looks stable while the EV bound decays is a wallet whose entries are getting more expensive.

Copy-trading a whale (a note)

Tracking isn't copying. If you want to mechanically copy a whale's trades, read Copy trading Polymarket responsibly first — the mechanical trap is that by the time you see a whale's trade, the price has already moved. You enter at a worse price than they did. That slippage eats most of the theoretical edge.

Common patterns by whale type

Different whales leave different tracks. Useful to know which kind you're following:

• Narrow-domain specialist — edge concentrated in one category, small-to-medium sizes, activity that spikes around news cycles.
• Full-time sharp — broad category coverage, consistent sizing, rarely spikes, an EV lower bound that stays above zero across a deep sample.
• High-variance operator — massive sizes, strong category concentration, and drawdowns to match. Check the worst day before following.
• Market maker — high volume, flat directional PnL, profit from the spread. The dossier's verdict chip labels these, and their entries are not a directional read.

Next

• Alerts and delivery — presets, per-wallet filters and the opt-in model.
• Copy trade safely — the method for acting on a wallet you track.

FAQ

How fresh is the data?

Trades land on CrowdIntel within ~30 seconds of confirmation on Polygon. The indexer runs continuously. There's no cache in front of wallet dossiers — every page load is live data.

Can I track a wallet anonymously?

Browsing is free and unauthenticated. Adding a wallet to a persistent watchlist requires login (via Clerk, email or Google). No credit card or wallet connect required.

How many wallets can I watchlist?

There is no cap on following. There are caps on delivery: the free tier allows one alert rule over five watchlist wallets and twenty deliveries a day.
