Polymarket's onchain sports markets are indexed on The Graph

October 2, 2026

The Graph highlighted that Polymarket's onchain prediction markets for the current sports season — MLB playoffs, the WNBA Finals, NBA tipoff, and the NFL Sunday slate — are already indexed on The Graph Network. Developers can query the markets with Subgraphs, stream them with Substreams, or fetch data via the Token API, all without building custom indexing.

The tweet positions Polymarket's events as readily queryable onchain data following the fall sports calendar.
