Polymarket announced that it has acquired Dome, a Y Combinator-backed prediction market API startup, in a move aimed at expanding its developer infrastructure and strengthening its data and tooling ecosystem.
The acquisition was disclosed through coordinated announcements on X, formerly known as Twitter, by both companies. Polymarket confirmed the deal in a post welcoming Dome to the company, while Dome separately shared that it would be joining Polymarket to help scale its developer-focused API capabilities.
Dome has built a unified API designed to simplify access to prediction market data and infrastructure, serving developers seeking streamlined integrations. By bringing Dome in-house, Polymarket is positioning itself to enhance its platform for third-party developers, traders, and ecosystem participants who rely on programmatic access and real-time market data.
The transaction underscores Polymarket’s continued investment in infrastructure and developer tools as prediction markets gain broader adoption. While financial terms of the deal were not disclosed, the public posts confirm that Dome will now operate as part of Polymarket’s broader platform strategy.
The announcement reflects a growing trend among digital asset and prediction market platforms to vertically integrate key infrastructure components in order to improve performance, reliability, and developer experience.
