Kalshi Powers Up Institutional Trading with DoubleZero Edge Feed
Prediction market exchange Kalshi has launched its live order book data on DoubleZero Edge, providing real-time market data to traders through a dedicated fiber network. The integration makes Kalshi the first prediction market available through Edge and marks a significant milestone for institutional-grade market data distribution.
The rollout covers Kalshi's sports event contracts and crypto perpetual futures markets, with subscribers gaining access to Level 1 feeds containing top of book prices and trades, as well as Level 2 feeds providing the complete order book across every price level. DoubleZero Edge uses multicast technology to publish data once and distribute it simultaneously to connected subscribers.
This marks a shift from traders relying on Kalshi's public API and WebSocket feeds, which could require maintaining their own order book state and managing stream and request limits. The Edge feed provides a normalized view of the order book with no per-stream cap or per-request budget.
