About Dome
Summary
Dome builds a unified API layer for prediction markets, targeting developers who want to build on platforms like Kalshi and Polymarket. It provides access to live and historical market data, including granular datasets those platforms do not expose natively, through a single interface. Developers use it to trade programmatically, embed market data into products, or deploy strategies across multiple platforms, replacing the need to integrate each exchange separately.
Go-to-market
Developers and technical builders in B2B contexts adopt Dome directly through its API, a self-serve model where the product replaces bespoke, per-platform integrations.
