River Markets Raises $8.5M Seed for a Prediction-Market Prime Broker

The startup is building a prime brokerage for prediction markets: a single terminal and API to trade every venue like Kalshi and Polymarket, with cross-exchange routing and the pro order types desks expect, such as icebergs, pegs and stop-losses.


It is pitched as institutional infrastructure for one of crypto's fastest-growing arenas, event contracts.
