Data Sources
ImpliedData aggregates prediction market data from multiple sources. All data is cleaned, normalized, and unified into a single schema. Third-party data is used in accordance with its respective license.
Polymarket
Live and historical market data collected directly from the Polymarket Gamma API and CLOB API. Trade history via the Polymarket Data API.
Manifold Markets
Binary prediction market data from Manifold's public API. A play-money venue rarely included in third-party prediction-market datasets.
Myriad Protocol
On-chain prediction market data collected from the public Myriad Protocol API (api-v2.myriadprotocol.com). Markets on Abstract and Linea, normalized to YES-probability and unified into our schema alongside the other platforms.
Azuro Protocol
On-chain sports-betting odds reconstructed from Azuro's public v3 subgraphs (Polygon). A frozen historical archive, not a live feed — Azuro v3 went dormant in 2025, so this is a complete static dataset of resolved markets. Multi-outcome; offered separately from the prediction-market platforms. Human-readable market and outcome names derive from Azuro's GPL-2.0 dictionaries and are attributed to Azuro; the underlying odds, stakes, and timestamps are on-chain facts.
