Ultrahuman is making a renewed push into the U.S. smart ring market after securing approval for its new Ring Pro, giving the Bengaluru-based startup a path back into its most important geography. The clearance from U.S. Customs and Border Protection comes months after trade restrictions tied to a patent dispute with Oura sharply disrupted Ultrahuman’s U.S. business.
According to Chief Executive Officer and Co-Founder Mohit Kumar, the restrictions cost the company as much as $50 million in lost sales and pushed its market share down to low single digits by the end of 2025 after it had climbed as high as 24.6% earlier in the year. The Ring Pro, which features a redesigned unibody metal structure, is now central to Ultrahuman’s effort to rebuild distribution and recover ground in a category where Oura expanded its lead significantly during the disruption.
The stakes are high because the U.S. remains the largest smart ring market, accounting for about 60% of global unit sales in 2025. Ultrahuman has opened U.S. preorders for the Ring Pro ahead of a May 15 shipping date and expects it will take several months to fully restore its supply chain and market presence. At the same time, competition is widening beyond the U.S., with Oura entering India as Ultrahuman works to defend its home market. Kumar said the company is also developing another wearable focused on a different biomarker, signaling that Ultrahuman’s broader strategy extends past rings alone as it tries to scale in a market that is still taking shape.
