Oura, the U.S.-based health tech company known for its sleep- and health-tracking smart rings, confidentially filed for an IPO with the SEC, announced on Thursday, though the company did not specify a timeline beyond saying it “is expected to take place after the SEC completes its review process.” The company reached an $11B valuation following a $900M Series E funding round in October, and has sold more than 5.5M rings since its 2013 launch in Finland, with CEO Tom Hale telling CNBC the company could approach $2B in revenue in 2026 (roughly double its 2025 sales). Oura's newest model, the Oura Ring 4, can track over 50 metrics including blood oxygen, continuous heart rate, and metabolic health, with competitor Whoop having signaled that its recent $575M Series G round could be its last before an eventual IPO.
