Data licensing

Polymarket Data Licensing

Licensing decides what you can legally build, and Polymarket data comes in two licensed shapes: the open CC BY 4.0 dataset you may adapt and redistribute with attribution, and the subscription archive whose terms govern production use. This page maps them.

Layers

Two license shapes

The open Zenodo release is CC BY 4.0: share and adapt anywhere with attribution. The recorded rolling archive is a subscription service bound by its terms of service — access, rate limits, and redistribution are governed documents, not a license gift.

The honest rule of thumb: the sample is open, the service is licensed, and the venue's own official API data carries Polymarket's terms on top of whatever you build.

Build

Building within the terms

Products built on the archive (dashboards, models, published research) follow the service terms, typically allowing analytical use of queried data and clarifying bulk redistribution. The safest production pattern is reading the terms, citing the dataset, and keeping the open artifact for anything you publish.

Redistribution of third-party data is the recurring license trap: the open artifact authorizes it with attribution, and the paid service states its own boundary — the datasets guide treats the layers separately for exactly this reason.

Honest

The honest framing

Licensing is a contract, and this page is a signpost, not a lawyer: it states the layer structure and the attribution defaults so a builder asks the right question — which artifact, under which terms — before committing architecture and revenue to a data path.

FAQ

Can I redistribute Polymarket data?

The open Zenodo artifact permits redistribution with attribution under CC BY 4.0; the paid archive's redistribution boundary lives in its terms of service.

Can I build a commercial product?

Analytical use of queried archive data is the normal pattern; bulk redistribution and resale follow the service terms you accepted.

Which license applies to official API data?

Polymarket's own API data carries the venue's terms on top of anything you build.
