*DoubleZero Edge delivers data only and does not provide order execution.
DoubleZero Edge delivers Kalshi’s data exactly as it is, normalized into clean, ready-to-use books.
Powered by Kalshi Research, running on DoubleZero’s high-performance fiber network.
DoubleZero delivers data straight from Kalshi to Edge subscribers through its worldwide dedicated fiber network. Now anyone can get access to the quality of infrastructure usually available only to the largest institutions.
Delivered by multicast
The publisher emits once. The DoubleZero network replicates it to every subscriber simultaneously using multicast technology. No per-stream limits. No server-level fan-out.
A dedicated route for Kalshi data
Kalshi data carried over dedicated fiber.
Yes/No normalization.
Kalshi quotes both a Yes and a No side for every contract. The feed normalizes them into one consistent book per market. Subscribers see one clean view without reconciling two sides.
Always in sync
Snapshots cycle continuously in the feed. Join late or drop a packet – full book state rebuilds from the feed itself, no separate snapshot channel needed.
