Onchain prediction-market platform Polymarket has acquired Dome, a Y Combinator-backed startup, The Block reported on Thursday. The acquisition price was not disclosed.
Dome took part in the Y Combinator program in the second half of 2025 and provides an aggregated API for prediction markets. It supports developers in building apps, bots, dashboards and trading tools that work simultaneously across multiple prediction-market platforms, including Polymarket and Kalshi. Co-founders Kunal Roy and Kurush Dubash are both former founding engineers at blockchain developer infrastructure company Alchemy.
Earlier, Dome raised $500,000 from Y Combinator and $4.7 million in separate seed funding.
The acquisition aligns with Polymarket's ongoing distribution expansion strategy. Polymarket recently acquired U.S.-licensed derivatives exchange QCEX to re-enter the U.S. market, and has also signed a series of distribution deals with sports leagues including Major League Soccer and the National Hockey League, as well as media companies including Substack.
