A single-account model for institutional prediction markets
River Markets is building a prediction-market prime brokerage platform for institutional traders. It plans to let customers manage funds, positions and risk across multiple exchanges and clearing organizations through a single account, with support for financing arrangements and permitted over-the-counter transactions.
The registration concerns River Finance LLC, while the broader platform plans were described by River Markets. The report does not detail how customer assets would be held or how obligations would be allocated among the affiliate, exchanges and clearing organizations.
Founded in May 2026, River Markets said it had routed more than 250 million contracts for clients including hedge funds and proprietary trading firms. The company had previously completed an $8.5 million seed funding round.
