Smart rings race to crown as Oura files for IPO

Oura has filed to go public as rivals pile into the smart-ring space. The Finnish company says revenue reached about $1.21 billion for the nine months through June, with roughly 3.6 million rings sold in the last year and around 5 million paid members. As Oura rolls out the Ring 5, competitors such as Ultrahuman (Ring Pro), Circular (Ring 3), RingConn Gen 3, Samsung’s Galaxy Ring and Dreame are adding features like NFC payments, haptics, on‑device processing and ECG, signaling a shift from passive health tracking to a smartphone‑like experience on a tiny titanium band.
