A single-account platform for institutional traders

The company also plans to support financing arrangements and compliant over-the-counter trading; the report does not describe those services as already available.
Founded in May 2026, River Markets counts hedge funds, sports funds and proprietary trading firms among its clients. It previously raised $8.5 million in seed funding.
The report does not detail how customer funds would be held or allocated across exchanges and clearinghouses, or the terms governing the planned financing arrangements.
