Oura Unveils Ring 5, the Smallest Smart Ring Yet, and Sets Sights on 2026 IPO

AI Summary
Finnish‑American wearable maker Oura unveiled the Ring 5, the world’s smallest smart ring, and signaled its intent to go public later in 2026. The new 2.28 mm‑thin device, priced at £399 with a $5.99 monthly subscription, aims to boost its $11 bn valuation as the smart‑ring market accelerates.

Ring 5 Redefines the Smart Ring Form Factor

Oura introduced the Ring 5, a 40% smaller iteration of its flagship device, measuring just 2.28 mm in thickness. The ring packs the health‑tracking capabilities of a smartwatch—sleep, stress, readiness and heart health—into a jewellery‑like profile while extending battery life. It will ship on 4 June with a retail price of £399 (€399/$399) and a mandatory $5.99 monthly subscription.

  • 40% reduction in size versus Ring 4
  • Battery life increased (exact hours not disclosed)
  • Subscription‑based model adds recurring revenue

Financial Outlook: $1 bn Revenue Target and $11 bn Valuation

Oura reports roughly 5 million paying subscribers and a four‑fold revenue growth over the past two years, projecting $1 bn in revenue for 2025. The company is currently valued at about $11 bn ahead of an IPO slated for later this year.

Market Implications: Accelerating Smart‑Ring Adoption and Competitive Landscape

Analyst firm FDM CCS Insight estimates 4 million smart rings shipped in 2025, a figure that has more than doubled each year for the past two. While still dwarfed by the 175 million smartwatches shipped in the same period, rings are gaining traction among both traditional smartwatch users and those who prefer a less conspicuous device. Oura’s focus on sleep‑first tracking and a “female‑first” design philosophy differentiates it from larger players such as Apple.

What’s Next: IPO Timing and Expansion of Proactive Health Services

With a global footprint that now includes offices in Helsinki, London, Los Angeles, San Diego and dual headquarters in San Francisco and Oulu, Oura is positioning the Ring 5 as a gateway to broader health‑care services. Upcoming software features—such as a health radar for early detection of blood‑pressure spikes and GLP‑1 weight‑loss monitoring—signal a shift toward proactive health management. Investors will be watching the IPO filing later in 2026 for clues on how the company plans to monetize these new services and sustain its growth trajectory.
