Whoop has secured $575m in Series G funding, valuing the business at $10.1bn, with participation from international investors and professional athletes including Rory McIlroy and Cristiano Ronaldo.
The funding round was led by Mubadala Investment Company, alongside backing linked to Qatar Investment Authority and Saudi Aramco Oil Pipelines Company. Additional athlete investors include Virgil van Dijk and Shane Lowry, reflecting continued athlete involvement in sports technology businesses.
The company is expanding internationally, including in the UK and wider European market, as part of plans to grow its subscriber base and brand presence. The wearable technology sector has seen sustained growth, driven by demand for health tracking devices and performance monitoring, with major technology companies continuing to invest in the category.
Whoop reported significant revenue growth in 2025 and is recruiting across multiple markets as it targets further expansion. The business has also increased its visibility in professional sport, with usage among elite athletes and recent regulatory scrutiny over in-competition device use at major events such as the Australian Open.
