About |
Assymetrix is a prediction market intelligence and infrastructure company building the data layer, intelligence layer, and exchange layer the industry is missing.
The Assymetrix Vendor SDK provides the deepest independent prediction market dataset available — billions of rows of on-chain and off-chain data across Polymarket, Kalshi, and Limitless, normalized into a single unified schema. Coverage includes nearly 2 billion on-chain blockchain events going back to September 2020, over 270 million off-chain metadata records, over 200 million price snapshots, and a canonical normalization layer mapping markets, events, outcomes, trades, and orderbooks across all indexed platforms.
The data offering fills the vacuum created by Polymarket's February 2026 acquisition of Dome, the previously leading independent cross-platform prediction market API. Assymetrix is fully venue-neutral and independent — not owned by any prediction market exchange.
The Vendor SDK is a read-only REST API with tiered access starting at a free tier, a built-in developer playground, and API key management with tier-based permissions. Predict.fun integration is in active development, with additional platforms planned for Q2/Q3 2026.
The data infrastructure is the foundation for a vertically integrated prediction market ecosystem: data layer, intelligence platform with cross-venue dashboards and AI-powered signals, and a native Assymetrix exchange — built in that order, deliberately.
