Whoop Secures $575M Series G Funding at $10.1B Valuation to Advance AI-Powered Wearable Fitness Tech

Whoop, the Boston-based pioneer in wearable fitness technology, announced a massive $575 million Series G funding round on March 31, 2026.

This investment propelled Whoop to a staggering $10.1 billion valuation, a sharp rise from its $3.6 billion mark in 2021.

From Startup to Global Powerhouse

Founded in 2012 by Will Ahmed, Whoop began targeting elite athletes but has since expanded to over 2.5 million mainstream users worldwide.

The company's innovative subscription model provides free wearables while charging for personalized data insights, driving explosive growth.

In 2025, Whoop achieved 103% year-over-year bookings growth, reaching a $1.1 billion run rate and cash flow positivity.

Star-Studded Investors Fuel Expansion

Led by Collaborative Fund, the round drew heavyweights like Qatar Investment Authority, Mubadala, Abbott, and Mayo Clinic.

Celebrity backers including Cristiano Ronaldo, LeBron James, Reggie Miller, and Niall Horan underscore the brand's appeal in sports and entertainment.

AI-Driven Insights and Market Impact

Leveraging over 24 billion hours of physiological data, Whoop's AI delivers predictive health recommendations on sleep, recovery, and stress.

In a fitness wearable market rebounding from 2025 lows, Whoop stands out against rivals like Oura, which hit an $11 billion valuation last year.

Looking ahead, Whoop plans aggressive R&D investment and global pushes into Europe, the Middle East, Latin America, and Asia.

To support this vision, the company is hiring for over 600 roles, signaling sustained innovation in personalized wellness.
