Overview
- Kalshi and DoubleZero began offering the live order‑book feed on Wednesday, August 12, 2026, giving subscribers sequenced top‑of‑book and full‑depth data for sports event contracts and crypto perpetual futures.
- DoubleZero Edge uses multicast over dedicated fiber to publish the same machine‑readable feed simultaneously to connected firms, removing the need for traders to rebuild Kalshi’s book from public APIs.
- Kalshi will forgo its share of Edge subscription revenue for the first year so initial pricing reflects only network delivery, but the companies have not disclosed subscription fees, measured latency, or the number of early customers.
- DoubleZero Edge provides market‑data transport only and does not execute trades, while the integration targets algorithmic and high‑frequency desks that need deterministic, low‑latency order‑book access.
- The launch comes as Kalshi expands institutional access but faces active state court challenges to some sports contracts, a development that could shape which markets remain available through the feed going forward.
