Top Holders for Polymarket
On any Polymarket market page, the Top Holders tab shows the biggest Yes and No holders, but their stats hide behind one-by-one hover tooltips. This tool loads everything at once, in your browser.
Open the toolWhat it shows
All the stats, both sides, one click.
- The combined all-time Profit/Loss of the top 20 Yes holders vs the top 20 No holders: you instantly see which side the most profitable traders are on. The winning side is highlighted.
- The aggregate positions value and traded volume of each side.
- The full top-20 tables side by side: rank, profile link, shares held, positions value, all-time P/L, traded volume. The exact stats of the hover tooltip, loaded at once for all 40 profiles, with live progress.
- Works on market pages and multi-market event pages, with a market selector, including resolved markets.
- Nothing to install: it runs in your browser, and a bookmarklet opens the market you are reading in one click, straight from Polymarket.
How it works
Paste the URL of a Polymarket market into the tool, or click the bookmarklet while viewing one. The page reads the market identifier from that URL, then queries Polymarket's public APIs from your browser. No install, no account, no setup, no tracking, no data collection. All displayed data is public. Unofficial: not affiliated with or endorsed by Polymarket.
Privacy policy
Top Holders for Polymarket does not collect, store, or sell any personal data. It has no backend, no account, no analytics, no tracking, and no advertising. It is not affiliated with or endorsed by Polymarket.
What happens when you run the web tool
- The web tool is a page: there is nothing to install and no permission to grant. The only thing it reads is the market URL you hand it, typed into the field or carried by the ?url= parameter of the address. It never sees your other tabs, your history, or any page you visit.
- If, and only if, that URL is a polymarket.com market or event page, the market identifier contained in the URL (the "slug") is sent to Polymarket's own public APIs (gamma-api.polymarket.com) to identify the market. That identifier is the only thing you hand the tool that ever leaves your device, it is sent only to Polymarket, and only to run the analysis you asked for.
- The page then queries Polymarket's public APIs (data-api.polymarket.com, lb-api.polymarket.com) for public market data: the top holders and their public trading statistics. These requests contain only public market identifiers and public wallet addresses returned by Polymarket itself, never anything about you.
- Market icons and trader profile pictures are loaded from Polymarket's image host (polymarket-upload.s3.us-east-2.amazonaws.com). As with any image load, that host sees your IP address. No other image host is allowed by the page's Content Security Policy.
- All requests are anonymous: no cookies, no credentials, no user identifiers.
- Nothing is written to disk or to browser storage. The tool page loads no third-party script: its Content Security Policy allows scripts from this domain only. No data is shared with or sold to any third party.
What the Firefox add-on does differently
- It reads the URL of the active tab, and only at the moment you click its button. That is the activeTab permission Firefox names when you install it. It never reads the content of a page, and does nothing on any page you have not sent it to.
- The three other permissions Firefox names are the three Polymarket APIs listed above, and nothing else. They let the add-on call them from your browser, exactly as the web page does.
- Everything else on this page holds unchanged: the same requests, the same public data, no storage, no third party, nothing that leaves your device except the market identifier.
