Smart Ring Market Heats Up as Oura Goes Public, Rivals Rise
Oura has filed for an IPO, with revenue nearly doubling to $1.21 billion and 5 million paid members. However, the smart ring market is becoming increasingly competitive, with rivals like Circular, RingConn, Ultrahuman, Samsung, and Dreame introducing innovative features. These include contactless payments, haptic feedback, on-device computing, and even touchpads. The competition is shifting beyond health tracking to incorporate smartphone-like functionalities, potentially transforming smart rings into on-finger devices. Ultrahuman, which raised $70 million from Qualcomm's venture arm, is developing a ring that can run software directly. Circular's upcoming Ring 3 series will feature NFC payments and FDA-cleared ECG. This landscape highlights the rapid evolution and growing complexity of the wearable technology sector.
The smart ring market is growing, but this article is primarily a consumer tech roundup, not directly about advertising or marketing technology. The relevance is moderate, as smart rings could become new ad channels or data sources, but it is not a major industry shift.

Ultrahuman Launches Ring Pro Amid Oura Patent Battle
Ultrahuman unveiled the Ring Pro, a third-generation smart ring with up to 15 days of battery life, a redesigned form factor and a $479 price, as it seeks to restore U.S. sales disrupted by a patent dispute with rival Oura. The company opened global preorders (U.S. excluded) with shipments starting in March and has submitted the redesign to U.S. Customs and Border Protection for import clearance. Ultrahuman also introduced Jade, a real-time "biointelligence" system for live health insights. The startup said it is operating at an annualized revenue run rate of about $150 million, reported $64 million in operating revenue for the year ended March 2025, and has raised roughly $55 million since founding in 2019. Legal actions include an ITC ruling favoring Oura and a pending patent suit in Delhi.
Oura confidentially files for IPO
Oura, the maker of the health-focused Oura Ring, has confidentially submitted a draft registration for an initial public offering to the U.S. Securities and Exchange Commission. The company said timing will depend on the SEC review process and market conditions. Oura reported it is on track to surpass five million paid members this quarter and said total revenue has grown fourfold over the past two fiscal years. The company was valued at $11 billion in October after a $900 million Series E round and has raised more than $1.5 billion to date. Oura — which moved its headquarters from Finland to San Francisco — says it has expanded its product beyond sleep tracking into broader health, analytics and AI-driven preventative health features.
Oura Repositions Ring with Oura 5 Product Launch
Oura has broadened its positioning from a sleep-tracking device to a wider wellness brand as it launches the Oura 5, a 2.8 mm smart ring the company calls the smallest and smartest on the market. The 11-year-old company says its product can track over 50 health and wellness metrics and has updated its app to add features such as an AI-powered glucose monitor and live exercise tracking. Oura has kicked off what it bills as its biggest campaign ever to support the new hardware and app features. Doug Sweeny, Oura’s chief marketing officer, said the product began as a sleep tracker and marketing has evolved alongside the technology. The ring has been adopted by high-profile users and the launch reflects Oura’s move deeper into consumer wellness marketing.
