RedStone partners with Kalshi, providing oracle infrastructure for real-time prediction market data on a wide range of topics, markets, and contract elements, enabling Kalshi’s data layer to be available on 110+ chains and to builders and developers everywhere.
RedStone is one of the oracle providers delivering data for Kalshi markets, but the only one running a pull-based architecture across more than 110 networks, including HyperEVM, TON, Sui, and MegaETH testnet. This wide network coverage significantly expands Kalshi’s potential reach and distribution. Beyond its pull-based model, RedStone is fully equipped to provide a push oracle for Kalshi data feeds at any time, which is the standard relied upon by roughly 90% of DeFi’s total value locked. This flexibility positions RedStone as a uniquely versatile oracle provider capable of serving the broader market’s needs.
By combining reliable market data delivery with broad multi-chain coverage, the Kalshi & RedStone partnership marks a key milestone for ecosystem builders, especially participants in the Kalshi Builders Program, who chose to build on Kalshi-sourced data that RedStone delivers in a pull-based model across 110+ chains.
0xUltra from Kalshi had this to say:
“Kalshi’s cooperation with RedStone is especially important for builders who enjoy the robust Push model oracle. It is another fundamental milestone bringing Kalshi onchain, step by step. Now, builders in the Kalshi ecosystem will benefit from both Pull and Push oracle models, based on needs, ensuring Kalshi has comprehensive data feed support.” — 0xUltra
Kalshi Is the Superset of Markets
Kalshi is the first CFTC-regulated exchange dedicated to predicting the outcome of real-world events – anything with a forecastable probability or a binary outcome becomes a market. Users can trade on everything from “Will Taylor Swift be mentioned on Good Morning America?” to “Will Donald Trump announce a BTC Reserve?”, from NFL matchups like Chiefs vs. 49ers to the U.S. presidential election. The platform is scaling so fast and is so popular that annualized trading volume is already tracking above $50B.
And that’s just the exchange part of the business.
Beyond being the top CFTC-regulated prediction exchange, Kalshi is a real-time index of human conviction, a continuously updating data layer on culture, sports, politics, and markets. That turns Kalshi into a buildable platform, where institutions, protocols, and developers can ship applications on top of RedStone-delivered live data.
The Journey of Getting Kalshi Onchain
Make no mistake about it: The Kalshi crypto team follows a multi-stage roadmap to get Kalshi onchain. This journey starts with data, and RedStone is proud to be its partner on this first step.
Where The Journey Begins
RedStone has gained expertise in a variety of market data, supports over 1300+ assets, 110+ chains, and 170+ clients. Our modular architecture allows us to integrate chains, applications, and protocols in a fraction of the onboarding time required by legacy oracles.
This initial integration between Kalshi and RedStone makes available real-time prediction data in a standardized and easily consumable way and will be initially focused on these markets:
- New York City Mayor Election
- Democratic Nominee 2028
- Number of rate cuts in 2025
In conjunction with Kalshi and the builders on Kalshi whom we serve, we will establish an integration roadmap on which markets and real-time prediction data will be supported in the next several stages.
Additionally, we understand the need for verifiable and auditable data, and we will be adding those unique features and will be working closely with Kalshi on the roadmap.
If you could have any market data from Kalshi onchain, what’s your wishlist?
What This Means For Builders
Having Kalshi prediction market data onchain, with distribution to 110+ chains, creates a new frontier of development – a greenfield of opportunities for developers. With such a blank canvas, you’ll be able to experiment, build, and create new products, new features, and new ways of interacting, understanding, and using Kalshi real-time prediction market data.
If Kalshi data were available onchain today, what would you build with it?
Quote from our COO and Co-founder, Marcin Kaźmierczak:
“Prediction markets have proven to be one of the major growth motors for crypto in 2025. We are dedicated to innovating in that category, increasing transparency, trust, and capabilities to build new solutions based on data from such venues. We are glad to support Kalshi’s multi-stage expansion onchain.”
Next Steps
The partnership between Kalshi and RedStone will continue to grow as we support more markets and make them available onchain. And we aim to have a deeper integration by providing more features and white-glove support in service of Kalshi, our partner, and for developers building on Kalshi.
By builders.
For builders.
