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.
