Oura, the Finnish company that created the ring-shaped health tracker worn by millions worldwide, has confidentially submitted draft paperwork to the US Securities and Exchange Commission for a proposed IPO, according to several reports.
While the number of shares and the expected price range remain undisclosed, the company had a recent funding round in the fall of 2025 that valued the business at around $11 billion (€9.5bn), more than double the $5 billion (€4.3bn) valuation it earned in a previous round in 2024.
According to CEO Tom Hale, more than 5.5 million Oura rings had been sold up to the end of last year’s third quarter.
At the time, Hale also projected that the company would reach $2 billion (€1.7bn) in annual revenue in 2026 compared with $500 million (€430mn) just two years ago.
The move towards an IPO puts a European wearable brand on Wall Street’s radar at a time when investor appetite for consumer health technology appears to be returning.
Oura has become a standout name in the fast-growing smart ring category, competing against smartwatch giants such as Apple, Garmin and Samsung, while carving out a niche with a distinct piece of hardware that some consumers find less obtrusive.
Over the past two years, the company has expanded aggressively into software, subscriptions and AI-powered health analysis. Its wearable platform now focuses on long-term health signals including sleep, readiness, heart rate, stress and recovery.
More recently, Oura has pushed further into women’s health and AI-based personal coaching, including tools designed to interpret physiological data and provide tailored wellness recommendations.
Analysts see that transition from device maker to subscripton-based health platform as central to its IPO pitch as the firm is currently on pace to surpass 5 million paid members.
A European tech champion heading to US markets
The IPO filing marks a significant moment for one of Europe’s most prominent health tech success stories.
Founded in Finland and developed around research into sleep, recovery and biometric monitoring, Oura has grown from a Nordic hardware start-up into a global player in the wearable market.
However, for Europe’s start-up ecosystem, Oura’s planned listing carries broader significance.
While its roots and design philosophy are deeply tied to Finland, the company recently transitioned to a US-based parent company, named Oura Inc. and headquartered in San Francisco, to access American venture capital while keeping its European operations.
Its decision to prepare for a US listing rather than a European one reflects a wider pattern among high-growth European tech firms seeking deeper capital markets and greater visibility among global investors.
The planned flotation arrives during renewed debate over whether Europe is losing some of its most successful technology companies to US exchanges.
Oura joins a growing list of European-founded businesses choosing Wall Street as their route to public markets, drawn by scale, liquidity and stronger investor familiarity with consumer technology.
The company’s IPO will also be seen as a test of investor sentiment towards wearable technology after a mixed few years for the sector.
Unlike smartwatches, smart rings remain a relatively young category, though interest has accelerated rapidly.
Oura is widely viewed as the segment’s category leader and its public debut could offer a clearer benchmark for how markets value next-generation health hardware combined with software subscriptions and AI services.
