Whoop, the fitness and health tracking wearable company, has closed a $575 million Series G funding round at a $10.1 billion valuation — nearly triple its last reported valuation of $3.6 billion — in a deal that brings together sovereign wealth funds, major health institutions, and some of the world’s most recognizable athletes.

The round was led by Collaborative Fund and includes participation from Mubadala Investment Company, Qatar Investment Authority, 2PointZero Group, Abbott, Mayo Clinic, Macquarie Capital, IVP, Foundry Group, Accomplice, Affinity Partners, Glade Brook, B-Flexion, Promus Ventures, and Bullhound Capital. Individual investors include Cristiano Ronaldo, LeBron James, Rory McIlroy, Reggie Miller, and Niall Horan, among other prominent athletes and celebrities.

The company has now raised roughly $900 million in total since its founding.

One notable addition to the cap table is Abbott, the medical device giant. Whoop founder and CEO Will Ahmed told me the partnership signals a broader push into health and medical capabilities, though he noted there is “more to come” on that specific announcement.

The funding arrives as Whoop hits some major business milestones, by Ahmed’s telling. The company exited last year at a $1.1 billion bookings run rate, up 103% year over year. Talking with TechCrunch last week, Ahmed made a point of explaining why bookings is the right metric to focus on: when you’re shipping millions of hardware units around the world while running a subscription business, investors need to understand the cash dynamics of managing all of that simultaneously — inventory, hardware costs, and recurring revenue at once. It’s a more complex picture than a pure software company, and bookings captures it best.

As for what comes next with all that capital, Ahmed pointed to talent and hiring, marketing and brand awareness, and continued R&D investment, along with accelerating international expansion.

The obvious question looming over a round of this size at this valuation: Is an IPO coming? (Rival company Oura is reportedly talking with bankers about staging its own this year.) Ahmed said the company is doing “a lot of the no-regrets work to be a public company” but stopped short of signaling any imminent plans to list.

Given that Whoop is a consumer brand with major name recognition among health-conscious and performance-oriented users, it’s the kind of company that could generate real retail investor enthusiasm whenever it does decide to make that move. In the meantime, Whoop has much more runway, and a much bigger number next to its name.
