Kalshi becomes first prediction market to stream full order books on DoubleZero
Kalshi has become the first prediction market to stream full order books through DoubleZero, a data infrastructure provider. The integration gives institutional traders direct access to Level 1 and Level 2 data on sports and crypto perpetual futures markets without reconstructing the book from APIs. The feed runs on DoubleZero Edge, a dedicated fiber multicast network. Kalshi head of institutional Andy Ross said firms trading on the platform want institutional-grade infrastructure across all venues.
Kalshi is now wired into the same data transport infrastructure that equity exchanges use, which changes who can trade its markets competitively. Institutions that already pay for DoubleZero feeds to reach stock exchanges can add Kalshi with no new terminal build, collapsing the setup barrier that has kept event contracts on retail platforms. Firms with latency-sensitive strategies now have a path to treat prediction markets as a core asset class rather than an experimental sleeve.
The move also raises the data arms race stakes for Polymarket, ForecastEx, and any rival that wants institutional flow. Kalshi can convert connectivity into volume, it forces competitors to match infrastructure spend before they can match contract variety. A prediction market without exchange-grade feeds risks being screened out of institutional allocation models entirely.
