Kalshi has begun distributing its live order book data through DoubleZero Edge, marking the first time a prediction market has offered real-time market depth over the platform’s dedicated fiber network. The service, announced on August 12, 2026, initially covers the exchange’s most actively traded sports event contracts and crypto perpetual futures.

Subscribers receive both Level 1 data, which includes top-of-book prices and completed trades, and Level 2 data showing the full depth of buy and sell orders across multiple price levels. The information arrives in a sequenced, machine-readable format designed for direct integration into automated pricing, hedging, and trading systems.

Institutional Access to Prediction Market Liquidity

Before the launch, trading firms typically assembled order book state by collecting individual responses from Kalshi’s application programming interfaces and reconstructing the book on their own servers. DoubleZero Edge packages the data as a subscription product, removing much of that internal processing work.

The feed uses a multicast distribution model. A single copy of the data is published once and delivered simultaneously to all connected subscribers over dedicated fiber rather than the public internet. This approach mirrors systems long used by traditional exchanges such as the New York Stock Exchange, Nasdaq, and CME.

DoubleZero previously launched an Edge public beta focused on Solana validator transaction data. The Kalshi integration expands the service beyond blockchain data into regulated prediction markets and perpetual futures.

Commercial Terms and Future Plans

Kalshi is waiving its normal share of subscription revenue for the first year. Under DoubleZero’s standard model, data publishers receive a percentage of fees after a protocol burn. With the waiver in place, initial pricing is based solely on network delivery costs rather than an additional data-licensing charge from the exchange.

Trading firms must still subscribe to DoubleZero Edge and meet its connection requirements. Neither company disclosed specific subscription prices, the number of initial customers, or independent latency measurements for the Kalshi feed.

Historical data is not included in the initial release. DoubleZero stated it intends to add historical Kalshi information in a later version, though no timeline or pricing details were provided.

Context of Growing Prediction Market Activity

The data feed arrives as trading volume across prediction markets has increased. Combined July volume across major platforms reached approximately $50.6 billion. Kalshi accounted for the majority of that activity.

Kalshi’s crypto perpetual futures, including its Bitcoin perpetual contract, were introduced after Commodity Futures Trading Commission approval earlier in 2026. These products provide U.S. traders with regulated access to derivatives previously available mainly on offshore venues. The new Edge connection now delivers the order books for those contracts alongside the sports markets.

The service is available immediately to DoubleZero Edge subscribers. Published market data is supplied by Kalshi Research.
