Kalshi Adds Wall Street-Style Data Feed

The update

Kalshi is adding a low-latency market data feed from Solana-based DoubleZero to its order book. The integration aims to provide institutional traders with a machine-readable view of prediction market data, similar to infrastructure used by traditional exchanges like the NYSE and Nasdaq. DoubleZeroEdge functions as a transport layer, sending live exchange and onchain data over dedicated fiber to distribute it simultaneously to all connected traders.

Why it matters

High-speed data access is critical for institutional participation in markets. By leveraging DoubleZero’s dedicated fiber network, Kalshi seeks to reduce the latency gap between crypto and traditional finance. This move signals a push to capture institutional volume in prediction markets, which are increasingly used for pricing derivatives and hedging risk on macroeconomic events. Sports ranks as the second-largest category on Kalshi with 37.8% of weekly notional volume, followed by crypto in third place, at 20.3%.

What to watch

Whether this infrastructure upgrade leads to a measurable increase in institutional trading volume on Kalshi. The company is prioritizing its most actively traded contracts, including crypto perpetual futures, in the initial rollout. Additionally, readers should watch for the next official update regarding the ongoing jurisdictional dispute between state regulators and the federal Commodity Futures Trading Commission (CFTC), which has temporarily blocked Kalshi from allowing residents to place bets on sporting events.
