Summary
$8.5 million in seed funding will help River Markets expand a platform that lets professional traders access multiple prediction markets from one interface, targeting a fragmented market the founders say institutions cannot easily navigate alone.
Haun Ventures led the round, which closed in July, with Y Combinator, Coinbase Ventures, Qube Research Technologies and angels from firms including Google, Nvidia, JPMorgan and Citadel also participating.
Since launching in May, River Markets has offered software, data links and risk-management tools designed for larger orders, and CEO Oscar Levy said the platform is on track to surpass hundreds of millions of dollars in annualized trading volume by year-end.
Institutional demand is rising across the sector: Kalshi said in May that institutional volume jumped 800% over six months, while Kalshi and Polymarket have recently handled block-style trades tied to carbon auctions and GPU-rental prices.
River Markets plans to use the capital to hire engineers, strengthen trading infrastructure and add sales and operations staff as prediction markets shift from retail-style venues toward institutional financial tools.
