Oura, Health Intelligence Platform via Smart Ring, Files for Nasdaq IPO

Oura, the Finnish company behind the popular Oura Ring, is reportedly raising nearly $875 million in new funding that would value the company at close to $11 billion — roughly double its December valuation of $5.2 billion, according to a Bloomberg News report cited by TradingView. The round could grow to more than $900 million and is expected to close by the end of the month. Oura says it does not comment on financing rumors or speculation.

The numbers behind this growth are striking. Oura has sold more than 5.5 million rings since launching in 2015, with over 2.5 million of those sold in just the past year. The company posted more than $500 million in revenue in 2024 — more than double the year before — and expects to hit $1 billion in sales in 2025. Oura plans to use the new funding to scale production, invest in development, and expand internationally.

Why This Matters If You're Watching Your EMF Exposure

For health-conscious parents and homebuyers already thinking carefully about wireless exposure at home, Oura's meteoric rise is a signal worth noting. As wearables like smart rings become mainstream — and as billions of investment dollars pour into scaling their production — more households will be adding another Bluetooth-connected device to their daily routine, worn directly against the skin for hours at a time.

Smart rings like Oura's are generally considered lower-emission than smartphones since they use Bluetooth Low Energy rather than cellular radios, and they don't transmit continuously. Still, for families trying to minimize overall RF exposure in the home, it's worth thinking holistically: every connected device adds to your environment's total electromagnetic footprint, even if each one is relatively low-power on its own.

That's part of why many EMF-conscious households focus on reducing exposure where it's easiest to control — swapping out higher-emission everyday appliances rather than trying to eliminate every wireless device. For example, choosing a low-EMF hair dryer for the bathroom or a low-EMF air purifier for the nursery or bedroom can meaningfully cut down on close-proximity exposure from devices that run for extended periods. Homebuyers renovating or building new can also look into options like EMF shielding paint to reduce ambient RF signal entering living spaces, particularly in homes near cell towers or dense Wi-Fi environments.

As wearable health tech continues to attract massive investment and adoption, staying informed about how these devices communicate — and making thoughtful choices about the rest of your home's electronic footprint — remains a practical way to balance the benefits of health tracking with EMF-conscious living.
