Kalshi launches first real-time order book streaming in prediction markets

Kalshi has started offering a real-time order book data feed through DoubleZero Edge, a market data transmission service built on a dedicated global fiber-optic network, The Block reported. It marks the first use of an ultra-low-latency multicast feed in the prediction market sector. Institutional traders had previously faced delays and the added step of rebuilding order book conditions from API responses. The service will initially provide order book depth data for major sports events and cryptocurrency perpetual futures contracts.
