Polymarket Wallet & Whale Trackers

What this category is for

Every product here answers one question about a prediction market: who is trading it. Paste an address and get its positions and profit; watch a feed of fills above a size floor; be told when a wallet you chose moves; get a score for an account's record. The market-level questions — how much volume, how deep the book, how a price compares across venues — are analytics and dashboards. Placing an order is trading clients and bots. And the raw positions and trades these products are built from are available as data in market data APIs.

What every card in this listing sells is a reading of public on-chain activity. None of them is a forecast of an outcome, and the ones that bolt a view onto the reading — a picks marketplace, a list of wallets to copy, a daily edition that states predictions as fact — carry the recommendations flag on their cards, with the sentence that says what is recommended and who places the order.

Where to start, by what you need:

• One address, free, no account: Predicts.guru, PredictFolio or PolymarketScan.
• A ranking whose exclusion rule you can read: OrcaLayer and Convexly. The head to head holds them against Airavat, Polysights and Predicts.guru on exactly that question.
• A notification when a wallet or a large trade moves: Polymarket Alerts on a phone, PolyAlertHub to Telegram and email, Polytrack for severity-scored flow.
• Polymarket and Kalshi in one feed: Polywhaler, with the depth caveat in the next section.
• Your own wallet, for a tax return: PolyTaxes for Form 8949 rows, PredictFolio for a yearly ledger, PolyWallet for a CSV of trade history.
• The data in your own code: OrcaLayer's REST and server-sent streams, PolymarketScan's keyless API and MCP server, Unusual Predictions's 42-endpoint API and WebSocket.

Why this is a Polymarket category

Wallet tracking exists where settlement is a public ledger, and among the large venues that is Polymarket. Every fill, split, merge and redemption is a transaction on Polygon, readable by address by anyone who indexes the chain. That is the whole of the raw material, and it is why fourteen of the fifteen cards here track wallets on Polymarket alone.

Kalshi and Polymarket US are regulated exchanges, and an account's positions on them are not published anywhere. Polywhaler carries Kalshi trades, and its docs set out the difference: a display name instead of an address, a shallower history, statistics that need a long record thinner, and no webhooks on the Kalshi side. PolyTaxes says plainly that off-chain Polymarket US activity cannot be inferred from a wallet. So a "cross-venue" wallet view is, in practice, a Polymarket wallet view with something else beside it.

A label is a rule somebody chose

Smart money, whale, sharp, insider, farmer: these are not properties of a wallet. They are the output of a rule, and the rules differ more than the words do. What separates the products in this listing is less what they show than whether they tell you the rule.

Published. OrcaLayer states its exclusions in numbers: a wallet whose average buy price is above 95 cents is a farmer, one with more than 500,000 trades at an average under 20 dollars is a bot, and four Polymarket router contracts are stripped out platform-wide. Its "Smart Money" badge needs a per-market win rate of at least 55%, positive profit and not being either. Its own April 2026 audit found that six of ten wallets with apparently flawless records were airdrop farmers — which is the reason the filter exists. Polywhaler centres its wallet score on 50, keeps volume out of it because volume is easy to wash, and marks wallets with fewer than ten decisive closed positions as provisional rather than ranking them.

Published, with the failures. Convexly publishes its methods index, its registered forward tests and its negative results, and prints how many wallets on a board were read in full — 31 of 42 on its 12 September 2026 board. One of its notes points its skill-versus-luck test at its own top-50 leaderboard and reports that none of the 35 readable wallets clears the bar.

Named but not weighted. Unusual Predictions, formerly Hashdive, names the inputs to its Smart Score — return, effective trade count, win rate, edge, sizing — and publishes no weights. Polytrack publishes its signal categories and keeps the thresholds private so they cannot be gamed. Airavat scores every trader 0 to 100 from named metrics, behind an invitation.

Not published. Polysights' insider finder comes with no methodology, and its terms page read "Under Construction" when checked. PredictFolio's profile score out of 100 has no method anywhere on the site.

Underneath all of them sits the same limit. A wallet is not a person. One trader can run several addresses and appear as several rows; one address can be a fund, a shared account, a bot or a market maker hedged somewhere the tracker cannot see. A leaderboard row means "this address has this record on this venue over this window", and the window matters: 24 hours, 30 days and all-time give three different top tens from the same data.

Whale, insider: no two products mean the same thing

Whale is a size floor, and the floor moves. PolymarketScan flags any single fill of 5,000 dollars or more. Polywhaler's tape starts at 10,000 dollars, 5,000 on Kalshi's quieter non-sports markets. PolyTrack's TradeFlow defaults to 10,000 dollars. PolyAlertHub's whale alerts start at 10,000 shares, which is a different unit — at 10 cents a share that is 1,000 dollars.

Insider is a pattern about a wallet, never a finding about a person. Polymarket Alerts names its three: a wallet whose first trade is large, a thin wallet that suddenly trades large, a dormant wallet that returns with size. Unusual Predictions ranks accounts by a Z-score for being new, concentrated and early. Polywhaler scores single trades 0 to 100 on timing, price impact, size and the wallet's past. A trader who opened a fresh wallet for privacy fits most of these patterns too. Polywhaler's "Vindicated" feed lists the flagged trades that won and gives no count of those that lost, which makes it a highlight reel rather than a hit rate. The guide to what wallet tracking shows sets out what the word can and cannot mean on a public chain.

How late is the data

A tracker reports a trade after it happened, and the gap is part of the product. OrcaLayer gives an index latency of 15 to 20 seconds as its own figure, not a commitment. Polywhaler states a median of about 30 seconds from fill to feed. PolymarketScan's agent API caches for 60 seconds and refreshes every two to five minutes, and its leaderboards are hourly. Polytrack delays its public stream by 15 minutes on purpose and not its paid dashboard. PolyWallet states its refresh interval three different ways on one site.

By the time any alert reaches you, the order it reports has already moved the book. The Unusual Predictions card puts it plainly: acting on a flag means following a wallet into a market after the price has absorbed what that wallet did.

Watching needs no key; three of these also trade

Reading the public record needs nothing from you but an address, and most of this listing stops there. Three cards go further, and are listed under trading clients and bots as well, because placing an order is a different job with different questions:

• PolyTrack, at polytrackhq.app, copies a wallet you enable. Automatic mode asks for your Polymarket API credentials and a private key, stored on its server; each copy carries a platform fee of its own, 2% of the trade at the entry rate; and the site publishes no terms of service.
• PolyAlertHub runs a terminal on a wallet it generates and holds for you; neither its terms nor its privacy policy mention it.
• Polywhaler's Orca places live orders only by hand — signed in your own browser wallet on Polymarket, with a Kalshi API key kept on its servers — and its automatic copying is a paper feature, in its own docs' words as read on 8 October 2026. The paper side carries the number worth reading before any copy feature: a portfolio priced at the fills a copier could actually have got rather than at the copied wallet's own, which the vendor calls a ceiling, not an estimate.

A copied position is the reader's own position, sized by the reader's own settings. Nothing about a wallet's past record on this venue says what it will do on the next question, which is a different question.

What to check before you rely on one

Who runs it. Several of these name no operator: Polytrack's terms are with "the operator of Polytrack" and a Gmail address, PolymarketScan names no company, PolyTrack publishes no terms at all. Two pairs of names collide: Polytrack at polytrack.cash and PolyTrack at polytrackhq.app are unrelated products, and Polywhaler's Orca is not OrcaLayer.

Which population the number is over. OrcaLayer counts 3.1 million wallets with a fill, 1.85 million past ten fills and 100 dollars, and a narrower set again for its rankings. Polytrack's aggregates are over its monitored set, not over Polymarket. Two leaderboards that disagree may be ranking different populations rather than measuring the same one differently.

What you may do with the output. OrcaLayer forbids reselling and using the data to train models; Convexly's self-serve licence is for one named person and forbids republishing to your own clients; PolyAlertHub's API is licensed for personal, non-commercial use; Polywhaler forbids redistribution. If the plan is to build something on a tracker's API, read that clause before the rate limit.

How the free tier pays for itself. PolymarketScan discloses that it earns a referral fee when you follow its links to Polymarket and trade there. Predicts.guru keeps a "Trade on Polymarket" link in its header. Neither makes the data wrong; both mean the page has a direction.
