WHOOP Closes $575M Series G at a $10.1 Billion Valuation

April 03, 2026 – The AI-powered fitness wearable startup attracts sovereign wealth funds, healthcare giants, and celebrity athletes as a sector-wide reset gives way to landmark deals.

The Deal

WHOOP has raised $575 million in a Series G round, pushing its valuation to $10.1 billion. This marks a near-tripling from the $3.6 billion valuation it reached in August 2021. Boston-based WHOOP was founded by Will Ahmed in 2012. It has now raised over $900 million in total venture funding.

Collaborative Fund led the round. Institutional participants include Qatar Investment Authority and Mubadala Investment Company. Healthcare heavyweights Abbott and Mayo Clinic also took positions. Their involvement signals a shift toward clinical-grade consumer health data.

A Star-Studded Cap Table

Individual investors add cultural reach to this round. Soccer icon Cristiano Ronaldo joined as a backer. NBA legends LeBron James and Reggie Miller also invested. Musician Niall Horan rounds out the celebrity cohort.

This blend is strategic. Sovereign wealth funds provide patient, long-term capital. Healthcare institutions provide legitimacy and data partnerships. Celebrity investors convert their own audiences into subscribers.

The Subscription Model

WHOOP’s business model is distinctive. The device itself is free. Revenue flows entirely from subscriptions. Members pay tiered monthly fees to access AI-powered health insights. The platform now serves 2.5 million members globally.

“WHOOP’s AI engine processes over 24 billion hours of physiological data, tracking sleep, strain, recovery, and long-term behavioural trends.”

Bookings grew 103% year-over-year in 2025. The company ended the year at a $1.1 billion annualised run rate. Crucially, it is cash-flow positive, a rare feature among growth-stage startups at this scale.

Market Context

The wearables funding environment has been choppy. Global venture investment in fitness and wellness startups totalled just over $5 billion in 2025. That was down from a peak roughly four years prior. Still, mega-rounds persist.

Finnish smart-ring maker Oura is the clearest comp. Oura closed over $900 million at an $11 billion valuation last October. Both companies compete on biometric depth over steps-counted simplicity.

The broader market opportunity is substantial. MarketsandMarkets projects the wearable technology market to grow from $84.5 billion in 2025 to $176.8 billion by 2030. That implies a 15.9% compound annual growth rate. Grand View Research estimates the market at $92.9 billion in 2025, reaching $230 billion by 2033.

What the Capital Does

WHOOP is hiring for more than 600 open roles. The capital targets R&D investment and global expansion. Key markets include Europe, the Middle East, Latin America, and Asia. The company’s hardware-free model lowers the barrier to international growth.

The wearable fitness technology market is forecast to expand at 10% CAGR through 2035, reaching $39 billion. AI integration is the primary driver. WHOOP’s head start in proprietary physiological data, 24 billion hours of it, is a meaningful moat.

Bottom Line

WHOOP’s Series G is not merely a big check. It is a thesis. Health wearables powered by AI and anchored in subscription revenue can achieve scale. Strategic backers like Mayo Clinic and Abbott suggest the next phase moves toward clinical partnerships. The company is cash-flow positive and has momentum. In a cautious funding market, that combination commands a premium.
