Company behind popular Ōura Ring files paperwork for IPO
The developer of a popular healthcare wearable announced that it quietly submitted paperwork to go public.
Ōura Health—the Finnish developer of a popular “smart ring” to track sleep patterns, heart rate, body temperature and a lot more—said in a statement that it’s “confidentially submitted a draft registration” to the Securities and Exchange Commission (SEC), the first step toward an initial public offering (IPO) for stock on an exchange.
For now, there was no information released on what the launch price of the stock will be, nor is it known how many shares will be issued and how the offering will affect the company’s ownership structure.
Still, it appears Ōura is ready to move forward. It said the press release revealing the upcoming IPO was released to comply with registration requirements of the Securities Act of 1933, which remains the primary federal law governing the offer and sale of securities.
Ōura added that the announcement should not be misconstrued as an “offer to sell or the solicitation of an offer to buy any securities,” as it’s for public awareness and legal compliance only.
In October, the smart ring maker received $900 million from investors to develop new technologies to support its core wearable business.
That same month, it made moves to earn clearance from the Food and Drug Administration (FDA) to allow its rings to gather data aimed at predicting elevated blood pressure risk.
Much of the smart ring’s core technology is based on gathering data, which is analyzed by artificial intelligence, to assess the health of the wearer. To date, the company has said its devices can assess over 50 core health metrics, with the ring gathering much of the data on its own through internal sensors.
Wearable data to predict opioid overdoses
In May 2025, the Digital Medicine Society—a nonprofit research group of which Ōura is a member, along with Duke University, Google Fitbit, UNC Chapel Hill, and others—announced it was conducting a study to examine how data from wearables can be used to assess the risk of opioid addiction relapse and prevent overdoses.
The study was said to be conducted using smartphone apps and consumer wearables, including the Ōura ring. Roughly 1,000 patients were signed up to participate, with researchers looking to see how valuable 30 predictors are in assessing opioid abuse risk among those who have a history of abuse.
The results of that initiative are still pending.
A date has not been set for Ōura Health’s IPO.
