Oura files for IPO following $11 billion valuation

On Thursday, Finnish smart ring company Oura announced that it has confidentially submitted a Form S-1 to the U.S. Securities and Exchange Commission in preparation for an initial public offering (IPO). A Form S-1 is the registration document required by regulators before a company can list its shares on public markets. The confidential submission allows the company to begin the regulatory review process privately. While SpaceX, the aerospace-AI-data center company associated with Elon Musk, also drew attention with its own IPO prospectus this week, Oura’s filing represents another anticipated debut. Since its founding in 2015, Oura has grown from a hardware startup into a player in the consumer health technology sector, offering an alternative to wrist-worn wearables.

The confidential filing follows a period of commercial growth and an increase in the company’s private market valuation. To support its expansion, Oura has scaled both its unit sales and its capital base. Key financial and operational metrics disclosed by the company include:

• Unit Sales: Oura has sold 5.5 million rings to date. This represents an increase from the 2.5 million rings the company had reported selling in the prior year.
• Series E Funding: The company raised $875 million in its Series E round—a late-stage funding round that took place last September.
• Valuation: The Series E round valued Oura at $11 billion. This valuation is more than double the $5 billion valuation the company secured during its prior funding round in 2024.

Oura has established a distinct position in the wearable health tracker market by offering a sleek, unobtrusive ring rather than a wrist-worn device. This design choice has allowed the company to differentiate its products from those of competitors, including Fitbit, Garmin, and Apple. The ring tracks various health metrics, including activity, sleep, and daily readiness, for customers around the world. In an effort to cater to its growing base of female customers, Oura also recently introduced a proprietary artificial intelligence model geared toward women’s health. The public listing will test whether the company can maintain this growth trajectory as a public entity.

Why it matters

Oura’s move to public markets highlights the rapid scaling of the wearable health tech sector, underscored by its valuation jump from $5 billion to $11 billion in just over a year. The transition demonstrates that specialized, single-form-factor health devices can achieve massive scale and command premium valuations even when competing against diversified technology giants.
