Prediction market infrastructure is getting a more institutional-style upgrade. Kalshi says its live order book for event contracts is now available through data provider DoubleZero Edge’s dedicated fiber network, allowing subscribers to consume real-time market depth in a machine-readable form.

The companies announced on Wednesday that the arrangement will be the first of its kind for a prediction market supplying its real-time order book data on sports and crypto perpetuals event contracts through that dedicated distribution channel. Instead of assembling market data from order books and API responses, users can subscribe to a purpose-built feed designed to reduce the engineering effort required to integrate prediction-market liquidity.

Key takeaways

Kalshi’s real-time order book for sports and crypto perpetuals event contracts is now distributed via DoubleZero Edge’s dedicated fiber network.
DoubleZero Edge positions the feed as a turnkey, machine-readable alternative to building infrastructure using raw order books and API responses.
Sports is Kalshi’s second-largest category by weekly notional volume, with crypto in third place, according to Dune data.
The move comes as Kalshi remains embroiled in ongoing US jurisdiction disputes over whether its sports event contracts are regulated as derivatives or treated as wagers.

Dedicated fiber distribution for prediction-market order books

At the center of the announcement is how market data is delivered. DoubleZero Edge provides a dedicated fiber network and a corresponding data feed, which the companies say will stream Kalshi’s live order book information for relevant contracts.

From a user perspective, that matters because prediction markets often require low-latency, structured data pipelines to support faster market analysis, algorithmic trading strategies, and more reliable execution. The companies’ messaging emphasizes that data access is a “critical part” of market structure, and they argue that the broader ecosystem has lacked similar distribution-grade infrastructure as crypto, perpetuals, and prediction markets have expanded.

DoubleZero co-founder Austin Federa framed the initiative as bringing “institutional-grade infrastructure” to industry participants. In practical terms, the pitch is less about changing the underlying contracts and more about improving how market participants can ingest and process market depth at scale.

Where Kalshi’s volume sits across sports, crypto, and exotics

The announcement also highlights Kalshi’s product mix. According to Dune data shared in the original coverage, exotics lead Kalshi’s weekly notional trading volume at 39.4%, followed by sports at 37.8%. Crypto ranks third at 20.3% in the same weekly notional-volume breakdown.

Sports being the second-largest category helps explain why the order book distribution focus includes sports event contracts. It also signals that demand for structured, low-latency access isn’t limited to crypto-linked products; it spans the broader set of markets Kalshi operates.

These percentages are based on weekly notional volume and are attributed to Dune via a referenced query on its platform. (See: Dune data.)

Regulatory pressure remains: sports contracts and competing jurisdiction claims

The new data distribution capability lands in the middle of a regulatory fight that has been escalating for months. Kalshi’s sports event contracts have become the subject of a jurisdictional dispute involving state regulators and the US Commodity Futures Trading Commission (CFTC).

State authorities have argued that Kalshi’s sports contracts amount to wagers and should therefore fall under state gambling laws. Kalshi and the CFTC counter that the contracts are derivatives, placing them under the CFTC’s exclusive authority.

Legal actions cited in the reporting illustrate how unsettled the status remains. In late June, a Michigan judge temporarily blocked Kalshi from allowing residents to place bets on sporting events. Around the same time, Kentucky filed suit against multiple prediction market platforms—including Kalshi and Polymarket—alleging they operate unlicensed sports betting services.

Nevada also issued a temporary ban on Kalshi earlier in March, according to the same reporting. Meanwhile, the CFTC has taken the opposite tack by suing several states. The agency’s argument, as described in earlier coverage, is that federally regulated event contracts fall under its exclusive jurisdiction.

For market participants, these disputes are more than legal background—they can affect where contracts are accessible and under what compliance frameworks traders can operate. Even as the infrastructure for order book delivery improves, the ability to participate may still depend on jurisdiction-specific rulings and enforcement outcomes.

Broader visibility for Kalshi markets

The story also connects Kalshi’s markets to broader consumer-facing visibility. Earlier in July, OpenAI began displaying Kalshi’s prediction market odds for FIFA World Cup matches in ChatGPT search results, according to prior coverage.

This kind of display can increase public awareness of event markets and may expand the audience beyond traditional traders and developers. However, it also underlines that prediction markets are increasingly part of mainstream information flows—an environment where legal clarity becomes even more important.

What to watch next

Kalshi and DoubleZero Edge’s dedicated fiber feed could make it easier for institutions and serious builders to integrate prediction-market order books without custom plumbing, but the larger question for users is whether contract access will remain stable as courts and regulators continue to argue over jurisdiction. Watch upcoming rulings and any further adjustments to where and how sports event contracts can be offered.
