What fitness band maker reached a $10 billion valuation in March 2026?

In March 2026, the fitness band maker Whoop achieved a significant milestone, reaching a valuation of $10.1 billion after successfully securing $575 million in Series G funding. This marked a substantial increase from its previous valuation of $3.6 billion in August 2021, highlighting the company's rapid growth and increasing influence in the wearable technology market. This impressive valuation underscores investor confidence in Whoop's unique approach to health and performance tracking.

Whoop differentiates itself from many traditional fitness trackers by offering a screenless wearable device coupled with a subscription-based platform. Rather than focusing on step counting, Whoop specializes in collecting and analyzing comprehensive physiological data, including sleep patterns, recovery metrics, and daily strain. This data provides users with personalized insights into their body's readiness for activity, helping them optimize training, improve sleep, and manage stress. The device itself is often provided as part of the membership, with the core value lying in the continuous data analysis and actionable feedback delivered through its app.

Initially popular among elite athletes and serious fitness enthusiasts, Whoop has steadily expanded its reach, attracting a broader audience interested in proactive health management. The company has seen remarkable growth, now boasting over 2.5 million members globally and reporting a 103% year-over-year increase in bookings in 2025. Its latest funding round saw participation from a diverse group of investors, including institutional firms and prominent athletes such as Cristiano Ronaldo and LeBron James, further solidifying its position as a leader in personalized, preventative health technology.
