Robinhood is serving as an underwriter on Oura’s S-1 IPO registration filing submitted September 3, marking the brokerage’s first underwriting assignment. It ranks 18th among the 18 banks in the syndicate, while Goldman Sachs, Morgan Stanley, JPMorgan, Allen & Co. and Jefferies are lead bookrunners. Oura is targeting up to $3 billion at a valuation above $16 billion, compared with roughly $11 billion after its Series E round in October 2025. Robinhood received regulatory approval to underwrite transactions in June 2026, extending its earlier IPO Access program. The company is also expanding prediction-market offerings through a Crypto.com partnership and reported strong August customer, asset, trading-volume and event-contract data. Robinhood shares rose 1.08% to $113.79 at publication, according to Benzinga Pro.
