Solana-based network DoubleZero is adding prediction market Kalshi's order book to its low-latency data feed, giving institutional traders a single high-speed connection to both onchain and Kalshi market data. The addition follows DoubleZero Edge's April 2026 launch and comes as more than 63% of Solana's mainnet stake has migrated onto the network.
DoubleZero is adding prediction market Kalshi's order book to its low-latency market data feed, moving to meet growing institutional demand for Wall Street-style trading infrastructure in crypto markets. The DoubleZero Foundation said the addition will give trading firms a machine-readable view of the prediction market for pricing, hedging and signal generation on Solana.
Level 1 and Level 2 data now flow through DoubleZero Edge
The product behind the integration, DoubleZero Edge, launched in April 2026, initially focused on delivering Solana's raw blockchain data, known as "shreds," with minimal latency. By August 2026, it had expanded to include full Level 1 and Level 2 order book streaming for Kalshi's sports contracts and crypto perpetual futures. Level 1 data shows the best bid and ask prices, while Level 2 reveals the full depth of the order book, every resting order at every price level. Before the integration, traders accessing Kalshi data had to rely on standard APIs, which are slower by nature.
DoubleZero has already found adoption on Solana's own network: over 63% of Solana's mainnet stake, roughly valued at $21 billion, has migrated onto it.
Institutions get one connection for onchain and Kalshi data
The foundation described DoubleZero Edge as a transport layer that sends live exchange and onchain data over dedicated fiber, publishing it and distributing it simultaneously to all connected traders. That is the same model, the foundation said in a Wednesday announcement, that has underpinned traditional financial exchanges such as NYSE, Nasdaq and the CME for decades. In traditional finance, institutions use specialized networks to access data at high speed; crypto traders still largely rely on the internet, and DoubleZero attempts to close that gap with a bespoke onchain system.
Kalshi, one of the world's two largest prediction markets alongside Polymarket, will provide its most actively traded contracts at rollout, including crypto perpetual futures. Prediction markets like Kalshi price the probability of macroeconomic releases such as interest-rate cuts and inflation statistics, geopolitical events and asset price moves — data that can move prices within milliseconds of release. According to the foundation's announcement, DoubleZero aims to give traders "all on one low-latency connection".
Kalshi's ties to Solana predate the data feed
Kalshi, which is regulated by the CFTC, tokenized thousands of its market offerings on Solana in December 2025, using DFlow for onchain trading and Jupiter for liquidity to turn its contracts into SPL tokens, Solana's native token standard. The DoubleZero feed extends that relationship, adding the infrastructure for sophisticated traders to monitor and react to Kalshi's order flow at speeds that matter for execution quality.
