Dome: Prediction markets API provider offering a unified API for developers to access live and historical data, analyze, trade, and build applications.
Key people at Dome.
Dome was founded in 2025 by Kunal Roy (Founder) and Kurush Dubash (Founder).
Based in New York, New York, Dome develops a unified application programming interface that enables developers to access live data, execute trades, and build applications across multiple prediction markets. The platform aggregates granular historical and real-time datasets, simplifying the technical process of embedding market data or deploying automated trading strategies on networks such as Kalshi and Polymarket. Operating with a core team of two employees, the infrastructure startup secured $500,000 in early funding through its participation in the Y Combinator accelerator program before raising an additional $4.7 million seed round. Following its rapid growth in the decentralized prediction market sector, the company was subsequently acquired by Polymarket to further integrate its specialized developer tools. Dome was founded in 2025 by Kurush Dubash and Kunal Roy, who previously worked together as founding engineers at Alchemy.

Key people at Dome.
Dome is a developer infrastructure platform that offers a unified API for prediction markets, integrating multiple platforms like Polymarket, Kalshi, Manifold, and others into a single, consistent interface. It simplifies access to real-time and historical market data, including granular datasets not natively available on individual platforms. Dome enables developers to trade, embed market data into products, and deploy cross-platform strategies efficiently, addressing fragmentation and siloed data issues in the prediction market ecosystem[1][2][3].

Dome was founded in 2025 by Kunal Roy, a Berkeley-educated engineer with deep blockchain and prediction market expertise, previously a founding engineer at Alchemy and an engineer at Cruise and Google. Kunal and his co-founder were instrumental in scaling Polymarket during the 2024 U.S. election, which inspired them to build a unified API to solve the fragmentation problem in prediction markets[4].
The idea emerged from the challenge developers faced accessing consistent, comprehensive data across multiple prediction platforms. Early traction came from developer adoption and partnerships with platforms like Polymarket and Kalshi, validating the need for a unified infrastructure layer[4].

Dome rides the growing trend of prediction markets as alternative data sources and decentralized finance (DeFi) innovation. The timing is critical as prediction markets gain mainstream traction for forecasting political, financial, and social events, yet remain fragmented across platforms. Dome’s unified API addresses this fragmentation, enabling broader developer participation and innovation.
Market forces favor Dome due to increasing demand for interoperable data infrastructure and developer tools in crypto and fintech. By standardizing access, Dome influences the ecosystem by lowering barriers to entry, fostering new applications, and accelerating the maturation of prediction markets as a financial instrument[1][3][4].

Dome is positioned to become the standard data layer for prediction markets, with strong momentum from YC backing and early platform partnerships. Future growth will likely come from expanding platform integrations, enhancing AI-driven analytics, and scaling developer adoption.
Trends shaping Dome’s journey include the rise of decentralized finance, AI-powered trading strategies, and increasing institutional interest in prediction markets. Dome’s influence may evolve from a developer tool to a critical infrastructure provider underpinning a new generation of financial products and market insights.
As prediction markets mature, Dome’s unified API will be essential for unlocking their full potential, tying back to its mission of simplifying and democratizing access to prediction market data[1][3][4].
