Oura Files for $3B US IPO at $16B+ Valuation, 47% Jump From September Series E

Smart-ring maker Oura is targeting a September US IPO to raise up to $3 billion at a valuation exceeding $16 billion, sources told Bloomberg on Aug 24. The mark would be roughly a 47% jump from Oura's $10.9 billion September 2025 Series E, and follows revenue growth from $500M in 2024 to a projected ~$2B this year. Goldman, Morgan Stanley, JPMorgan, Allen & Co, and Jefferies are underwriting; existing investors are expected to sell a significant portion of their stock.
