About Holdytic

Holdytic is a read-only window onto prediction markets. It surfaces live odds, trading volume, order-book depth and price history for the most actively traded markets, so you can see what the crowd expects without signing up for anything.

Where the data comes from

Every figure on the site is pulled live from Polymarket's public APIs. Nothing is cached for long, estimated or filled in by hand:

• Markets, categories and searchcome from the Gamma API. Category tabs query Polymarket's own tag ids, so each one is a real filter rather than a re-sort of what is already loaded.
• Price history and order books come from the CLOB API, one series per outcome token.
• Comments, top holders and trade activity come from the public data API.

Figures refresh roughly every 30 seconds while a tab is open, and polling pauses when the tab is hidden.

What it does not do

Holdytic places no orders and holds no funds. There is no wallet connection and no portfolio, and an account only signs you in — browsing needs none. Where an action needs a funded Polymarket account — placing a trade, posting a comment, bookmarking a market — the site links out to Polymarket instead of imitating the feature.

Nothing here is financial advice, and market data can be delayed or incomplete. See the Terms & Conditions for the full position.

Privacy in one sentence

Browsing needs no account, and the site runs no analytics and sets no tracking cookies; if you do create an account, sign-in is handled by Clerk. The Privacy Policy spells out the detail.

Built with

Next.js with the App Router, React, TypeScript and Tailwind CSS. Charts are drawn as inline SVG rather than pulling in a charting library, and their colours are checked for colour-blind separation against the page background.
