Skip to main contentPredictionData.dev is the most reliable prediction market data platform. All
data that is emitted from the exchange is captured with redundant websockets and
stored multi-region.
There are no rate limits on how many requests per second you make or how
much data you download! Our infrastructure can support terabytes of outbound data per second.
If you are interested in bulk exports to make backfilling your database easier,
reach out to [email protected] for daily parquet snapshots of the database!

Market Discovery
We employ a low-latency polling system to discover new markets. Markets are
being watched within 1 second of being created. Please contact
[email protected] for enterprise feeds with <100ms latency.
Data Collection
All data is collected on redundant websockets to avoid any dataloss. Collection
servers are colocated to exchanges to provide minimal packet loss and latency. For reference, p50 latency to Polymarket’s matching engine is <10ms.
Data Freshness
Exports of our internal database are made available through
datasets.predictiondata.dev at 2am UTC every day. If you require faster access
to data, please reach out to [email protected].
