Pyth Pro is a market-data product designed for high-frequency consumers: exchanges, market makers, and trading firms that need lower latency and richer market depth than the on-chain pull model offers. It's distinct from Pyth Core (the public, on-chain feed network) in delivery and economics, but uses the same underlying publisher set.
How it differs from Pyth Core
- Delivery: direct binary feed, not on-chain pull
- Latency: sub-millisecond aggregate updates
- Depth: Level-1 quote data, not just last price
- Commercial: paid subscription, not gas-funded
- Audience: institutions and exchanges, not smart contracts
Why it exists
On-chain consumers can tolerate sub-second update latency because block times set the floor. Off-chain consumers (exchanges matching orders, market makers quoting) operate below that floor and need a different distribution channel. Pyth Pro lets the same publisher firms monetize their data to that audience while keeping the on-chain feed network running.
Who uses it
Coinbase, BitMEX, Kalshi, Polymarket, and other major exchanges and prediction markets have signed on as Pyth Pro consumers, confirmed via Pyth's blog announcements throughout 2026.
