Real-time order book feed
The companies said the service is designed to provide a machine-readable view of prediction market data without firms having to reconstruct order book conditions from API responses, and Decrypt reported that Kalshi will waive its share of subscription fees during the feed’s first year.

Austin Federa, co-founder of DoubleZero, said data access is a “critical part” of market structure, and Decrypt added that the feed includes Level 1 data showing the best available prices and completed trades plus Level 2 data showing buy and sell orders across multiple price levels.
Cointelegraph reported that Kalshi’s live order book is now available through DoubleZero Edge’s dedicated fiber network, and TradingView said the initiative makes Kalshi the first prediction market to distribute its real-time order book data on sports and crypto perpetuals event contracts.
