Oura filed its public IPO registration on September 3, bringing the business behind its smart ring closer to the stock market. Founded in Finland in 2013, the company sells finger-worn sensors and software to people who want to understand patterns in their sleep, activity and recovery. The filing offers a clearer view of how that daily habit becomes a recurring-revenue business.
The ring collects measurements, but the app is where a wearer makes sense of them. Oura's Trends feature lets members compare sleep timing, activity and stress measures across days, weeks and longer periods. Someone trying to establish a steadier sleep routine can review changes in bedtimes and interruptions, then add tags for behaviors they want to track. Those associations can inform personal observations; they do not by themselves establish what caused a change.
Oura monetizes both the device and continued access to richer information. Its US membership costs $5.99 a month or $69.99 a year, with one month included for new members. The subscription unlocks detailed analysis, historical reports and additional features. Without it, owners of newer rings retain limited functions, including three daily scores. The commercial distinction is important: selling a ring starts the relationship, while useful ongoing software gives customers a reason to keep paying.
The registration statement reports $1.2145 billion in revenue for the nine months ended June 30, 2026, up 74% from the comparable period a year earlier. Membership contributed about $240.5 million, with hardware providing the rest. Oura reported five million paid members at June 30. These are period-specific company disclosures, not an annual revenue run rate, and they show a meaningful subscription stream alongside a still-larger hardware business.
Oura has applied to trade on Nasdaq under the symbol OURA. The preliminary filing leaves the offering price and share count unspecified and contemplates shares from both the company and selling stockholders. The filing begins a public-offering process; it does not establish a sale price or show that the offering has closed.
The next challenge is maintaining trust as Oura broadens what customers expect from a ring. MobiHealthNews reports that a proposed class action disputes its sleep-tracking accuracy; Oura contests the allegations and says the product is not a substitute for a clinical sleep study. The business needs customers to find its interpretations useful enough to renew, while clearly separating everyday wellness guidance from medical diagnosis.
