Polymarket acquires Dome to deepen prediction market infrastructure

Polymarket is making another big bet on the future of prediction markets by acquiring Dome, a Y Combinator-backed startup from the F25 batch that built a unified API designed to make prediction market data and tools easier for developers to use.

Dome co-founder Kurush Dubash shared the news in a LinkedIn post, reflecting on the startup’s original goal: “From day one, our mission was simple: make it easy and reliable to build in prediction markets. There’s no better place to push that mission forward than Polymarket.” He also expressed gratitude to backers including Will Ventures and Y Combinator, and described the Polymarket team as “the kind of partners every founder hopes for.”

Building a world class experience requires world class talent… Welcome to Polymarket, @GetDomeAPI.” The message underscores how seriously the company is taking the infrastructure side of its business as it scales.
