FinTech of the day: Dome

Post date :

Nov 23, 2025

One API to rule prediction markets.

Meet Dome (YC F25), the startup that eliminates the mess of prediction‑market data.

Platforms like Polymarket, Kalshi, and Metaculus all have different endpoints, formats, and authentication. Dome unifies them in a single API with real‑time and historical data across every market.

Developers pay a usage‑based fee and get a common schema, websockets for live odds, and built‑in hedging tools. It's the Plaid for prediction markets.

Over 50 developers have already built on Dome, including sports‑betting apps, forecasting dashboards, and automated trading bots.

Founders Kurush Dubash and Kunal Roy were founding engineers at crypto‑infra unicorn Alchemy and ran quant desks. They know how to build reliable data pipelines.

With prediction markets gaining regulatory traction in the U.S., Dome is betting on a future where every portfolio manager and researcher needs fair‑priced odds.

Which opaque market would you plug into a single API?
