Kalshi taps Solana platform for Wall Street-style high-speed data feed
Kalshi’s order book is adding Solana-based DoubleZero’s low-latency market data feed to meet institutional demand.
The DoubleZero Foundation described DoubleZeroEdge as a transport layer, sending live exchange and onchain data over dedicated fiber, distributing it simultaneously to all connected traders.
The model has underpinned traditional financial exchanges, including NYSE, Nasdaq and the CME, for decades, the foundation said. The growing presence of financial institutions in cryptocurrency brings with it increasing demand for Wall-Street style systems in digital asset markets, such as servers that offer split-second advantages when executing trades.
Kalshi is looking to meet that demand by adding Solana-based DoubleZero’s low-latency market data feed to its prediction market order book. The DoubleZero Foundation said this will provide trading firms with a machine-readable view of a prediction market for pricing, hedging and signal generation on Solana, one of the major layer-1 blockchains.
The foundation described DoubleZeroEdge as a transport layer, sending live exchange and onchain data over dedicated fiber, publishing the data and distributing it simultaneously to all connected traders. In traditional finance (TradFi), institutions use specialized networks to access data at high speed, whereas in crypto, traders still largely rely on the internet.
DoubleZero attempts to address that through a bespoke onchain system. “This is the same distribution model that has underpinned traditional financial exchanges, from NYSE to Nasdaq to the CME, for decades,” the foundation said in an emailed announcement on Wednesday.
Prediction markets like Kalshi provide a probability assessment of macroeconomic releases like interest-rate cuts and inflation statistics, geopolitical events and asset price movements. Such statistics have the ability to cause significant price movement within milliseconds of their release, hence the demand for a Kalshi feed built into onchain data infrastructure.
Kalshi, one of the world’s two largest prediction markets (the other is Polymarket), will provide its most actively traded contracts at rollout, including crypto perpetual futures, derivatives contracts allowing traders to speculate on an asset’s price without an expiration date.
DoubleZero aims to give traders “the complete picture of Kalshi,” according to Wednesday’s announcement, “all on one low-latency connection.” CORRECTION (Aug. 12, 2026, 17:30 UTC): Clarifies relationship with this new partnership.
