Boston-headquartered fitness tracking company Whoop has successfully closed a $575 million Series G investment round. This latest capital injection propels the company’s valuation to $10.1 billion, representing a significant jump from its $3.6 billion valuation established during its 2021 fundraising effort.

Collaborative Fund spearheaded the investment round. Additional institutional participants include Qatar Investment Authority, Mubadala Investment Company, Abbott Laboratories, Mayo Clinic, Macquarie Capital, and GP Bullhound.

A notable group of elite athletes also contributed capital as individual backers. Cristiano Ronaldo, LeBron James, Rory McIlroy, Reggie Miller, Niall Horan, and Virgil van Dijk all invested in this financing round.

Will Ahmed established Whoop in 2012. The company produces a display-free fitness monitoring band that continuously measures recovery metrics, sleep patterns, and physical exertion levels.

Unlike traditional smartwatches, the device doesn’t display notifications or provide smartphone connectivity features. This design philosophy differentiates it from devices like the Apple Watch, which merges fitness monitoring capabilities with comprehensive smartphone functionality.

Whoop operates on a membership-based business model. The wearable device comes bundled with the subscription, currently priced at $239 annually as of early 2026.

Impressive Financial Performance

The fitness tech firm posted 103% year-over-year bookings expansion. By the end of 2025, the company had established a $1.1 billion bookings run rate while maintaining positive operating cash flow.

Whoop’s membership base has reached 2.5 million users. Since inception, the company has accumulated more than $950 million in total capital raised.

Product Innovation and Healthcare Integration

Whoop unveiled its latest Whoop 5.0 device alongside a specialized Whoop MG model. The MG variant has obtained FDA authorization for clinical-grade ECG monitoring and blood pressure tracking capabilities.

The ecosystem incorporates an artificial intelligence feature named Whoop Coach, delivering customized workout recommendations derived from individual user metrics.

Oura Health, creator of the Oura Ring smart ring, represents Whoop’s primary competitor in the health wearable sector. Oura secured funding last autumn that elevated its company worth to $11 billion.

Whoop’s current workforce stands at approximately 800 full-time employees. Management intends to expand personnel by up to 75%, creating over 600 positions spanning software development, hardware engineering, sales operations, and marketing functions.

This substantial hiring initiative has fueled market speculation regarding a possible initial public offering. Company representatives have not publicly addressed any public listing intentions.

With its present $10.1 billion valuation, Whoop ranks immediately below Shield AI valued at $10.4 billion and Kraken at $10.5 billion among the highest-valued privately-held companies, based on Yahoo Finance tracking data.
