Kalshi adds DoubleZero real-time market data feed

Kalshi is adding a real-time market data feed from DoubleZero to stream live prices and trade updates to its trading platform.

The feed will deliver near-instant price and execution information from Kalshi’s order book into the trading interfaces used by market participants. Kalshi described the upgrade as intended to improve the speed and clarity of price discovery for users who trade contracts tied to economic indicators, political events and other measurable outcomes.

DoubleZero will provide the low-latency connectivity and data delivery layer to integrate that information into Kalshi’s front-end systems. The companies did not disclose detailed technical specifications for the connection.

The arrangement is aimed at publishing consolidated market data in real time rather than relying on periodic snapshots. Expected fields for such feeds include current best bids and offers, recent trade prints and market depth that third-party trading tools can consume. The firms plan to roll the integration into Kalshi’s platform and to clients that subscribe to direct data connections.

The change affects traders who execute event contracts on Kalshi’s exchange and firms that use programmatic access for strategies tied to short-term outcomes. Real-time data may shorten the time between price movement and execution for active traders and automated systems and can support more precise risk management for participants who hedge exposure across multiple event markets.

Kalshi operates as a federally regulated exchange for binary and other event-linked contracts, offering markets on macroeconomic releases, election outcomes and weather events. DoubleZero provides market data services and connectivity for trading venues and financial firms and has been building infrastructure to deliver streaming data to exchanges, trading firms and brokerages.

Exchanges commonly add direct data feeds to support institutional customers and algorithmic traders that require consistent, low-latency access to price movements. Exchanges can monetize feeds through subscription offerings to high-frequency traders and market makers, while retail customers may see improved on-screen pricing. Kalshi did not disclose whether the new feed will carry a separate pricing tier or be included with existing platform access.

Regulatory oversight for venue-distributed market data varies. U.S. exchanges must maintain fair and transparent execution practices. No financial terms of the partnership were released; the companies indicated they will provide further details about distribution channels and commercial terms as deployment proceeds.
