DoubleZero Embraces Prediction Market Data, Adds Kalshi Orderbooks to Edge Dataset

Kalshi, the world's largest prediction market, is now streaming its live order book through DoubleZero Edge, marking the first time a prediction market has distributed real-time data over a dedicated multicast fiber network. 

Once dismissed by traditional finance as yet another crypto-native fad, prediction markets are rapidly establishing themselves as institutional-grade trading venues and scaling the depth and complexity of onchain markets.

Following the Kalshi integration, professional market markets and high-frequency firms can now consume Kalshi's full book depth on the same rails that already deliver low-latency Solana block data to institutional subscribers.

Solana’s Professional Traders Need Better Market Data

Despite facing diminishing volumes in the wake of the FIFA World Cup, prediction markets have disproven their critics and cemented their position as a critical piece within the new world of financial infrastructure. 

Having eclipsed, then consumed the market, Kalshi is the undisputed champion of the prediction market race, consistently capturing over 80% of market share. As a result, Kalshi’s orderbooks have evolved from a speculative playground into a definitive source of truth, communicating essential data that can transform how traders navigate the market.

As of August 12, Kalshi market data is streaming through DoubleZero Edge. The new feed covers Kalshi's most actively traded categories at launch, spanning every sports event contract and crypto perpetual futures market. 

Subscribers receive both Level 1 data, covering top-of-book prices and completed trades, and Level 2 data showing order depth across multiple price levels.

"Traditional finance got this concept exactly right: data access is a critical part of market structure... DoubleZero Edge brings institutional-grade infrastructure into the hands of prediction-market traders with software-defined access. Kalshi coming online shows that Edge optimizes market data for any venue, onchain or off." - Austin Federa, DoubleZero co-founder

Until now, trading firms wanting a machine-readable view of Kalshi had to build it themselves.  Edge replaces that patchwork with a single multicast feed. The publisher emits data once, and DoubleZero's dedicated fiber network replicates it to every subscriber simultaneously, the same delivery model used by traditional exchanges like the NYSE, NASDAQ, and CME.

Blockchain-Based HFTs to Reap the Benefits of Improved Market Data

DoubleZero is pitching the feed squarely at market makers, quantitative desks, prop traders, and arbitrage bot builders. Unlike the average onchain trader, professional trading firms live and die at a microsecond level. Latency directly determines profitability, and Kalshi's public API path through a CDN (Content Delivery Network) leaves too much distance between the matching engine and the strategy.

Kalshi is waiving its share of subscription revenue for the feed's first year. Subscribers still pay DoubleZero network fees. but the waiver strips out the data licensing premium during the launch period. Historical Kalshi data is planned for a later release without a confirmed date.

From the outset, demand for Kalshi’s dataset is already apparent. Blockworks data suggests the DoubleZero Edge subscriber count has almost doubled in the past few days, rising from 105 on August 8th to 189 today.

What Does This Mean for Solana?

DoubleZero was born in Solana, and Edge's original product was delivering the network's shreds, or fractionalized pieces of data, to traders faster than the public internet. According to DoubleZero, that feed arrives first on more than 90% of slots for participating leaders.

The network's Solana footprint is substantial. DoubleZero's Q2 2026 update reported 462 connected validators representing 59% of Solana's mainnet stake weight, alongside $21.7 billion in total connected value.

Kalshi joining as the second Edge venue adds considerable breadth to the way Solana’s HFTs navigate onchain markets. A trading desk already consuming Solana block data through Edge can now add Kalshi's books into the fold, tightening the loop between offchain prediction markets and Solana's onchain venues.

If Solana’s micro market structure is to truly compete with the Wall Street incumbents and realize the Internet Capital Markets vision, professional traders need access to the best available data at the lowest possible latency. DoubleZero Edge’s Kalshi integration is a critical step towards this goal, making Solana’s HFT stack better informed and better equipped to compete in what co-founder Austin Federa is calling “New Finance”.
