Whoop has raised US$575 million in a Series G funding round that now values the company at US$10.1 billion. The financing, revealed on Mar. 31, nearly triples the firm’s last reported valuation and arrives as executives complete preparatory steps toward an IPO.
The capital will support international expansion and product development at a time when sleep-tracking wearables draw increasing attention from consumers and investors. Medical-device giant Abbott Laboratories (NYSE: ABT) (ETR: ABL) participated in the funding round as a strategic investor along with the Mayo Clinic.
Boston-based Whoop, founded in 2012, operates a subscription model centred on a wristband that collects continuous physiological data.
The company has more than 2.5 million members and reached a US$1.1 billion bookings run rate in 2025 while turning cash-flow positive.
The round brings total funding raised since founding to roughly US$900 million and includes other backers ranging from sovereign wealth funds to elite athletes.
Whoop wristband carries distinct sleep tech capabilities
What separates Whoop’s device from many other sleep trackers is its combination of features and continuous operation. The screenless wristband stays on the wrist 24 hours a day and lasts up to 14 days between charges.
It tracks sleep stages, heart rate variability, blood oxygen levels and ECG readings that regulators have cleared for detecting atrial fibrillation (irregular heartbeat rhythm).
Last year the band added blood-pressure insights, a metric fewer consumer sleep devices capture with comparable frequency. The system draws on more than 24 billion hours of aggregated user data and applies AI to generate daily scores for recovery and strain.
Users receive app-based guidance that links sleep quality to overall preparedness for dealing with daily challenges, encouraging adjustments in bedtime routines or workout regimens.
Independent tests — including from researchers at Antwerp University Hospital, teams at Central Queensland University and the University of Arizona — have shown Whoop outperforming some rivals in deep-sleep detection accuracy.
This focus on integrating sleep data with real-time recovery metrics distinguishes the band from rings or watches that often prioritize step counts or basic sleep summaries without the same depth of behavioural coaching.

Whoop reports hiring surge and new partnerships
The tech developer plans to hire more than 600 new employees worldwide in 2026. The roles span positions in software engineering, research and development, hardware design, product management and marketing.
Most positions will sit in the Boston headquarters. Additional openings will be available in North America, Europe, the Gulf region and Asia to support global scaling and AI-driven advancement.
Whoop formed new high-profile partnerships over the past couple of weeks. It signed a multi-year deal through 2029 with the French professional football club Paris Saint-Germain to serve as the official health and performance wearable for the club’s teams. Whoop also just became the official health and performance wearable partner for Premier Padel: the leading global professional padel circuit (a racket sport).
These ties underscore Whoop’s push to embed its sleep and recovery platform in elite sports.
The investor list tells you exactly what WHOOP is now.
$10.1 billion for a company that gives away a screenless rubber band. The device has no screen. No buttons. No display. The hardware is free with every subscription. WHOOP charges $199 to $359 per year for the right to look… https://t.co/YNj350e2WY
