Next step for Whoop (WHOO.PVT): a healthy IPO day.

The wearable device company β€” which dubs itself a "human performance company" β€” said Tuesday it raised $575 million in Series G funding at a $10.1 billion valuation. Rival Oura Health, maker of the Oura Ring, raised a $900 million round at a $11 billion valuation last October.

"It's our expectation this is the last round private round of financing that we'll do," Whoop founder and CEO Will Ahmed said on Yahoo Finance's Opening Bid (video above). "I mean, the business is now operating cash flow positive and did so in 2025. And so, ultimately, this $575 million really strengthens our balance sheet."

The latest round for Whoop was led by Collaborative Fund and includes participation from 2PointZero Group, Qatar Investment Authority (QIA), Mubadala Investment Company, Abbott (ABT), Mayo Clinic, Macquarie Capital, Glade Brook, B-Flexion, IVP, Foundry, Accomplice, Affinity Partners, and Bullhound Capital.

Prominent athletes and individual investors involved in the round include Cristiano Ronaldo, LeBron James, Rory McIlroy, Reggie Miller, Niall Horan, Karen Wazen, Virgil van Dijk, and Shane Lowry.

Ahmed said it was important to get backing from major healthcare players such as Abbott and Mayo Clinic because the company is now viewed as a play on the surging longevity space.

The capital raise lifts Whoop up one spot on the world's most valuable company list, according to Yahoo Finance data. It's just shy of the $10.4 billion valuation afforded to Shield AI (SHAI.PVT) and the $10.5 billion valuation on Kraken (KRAK.PVT).

Whoop disclosed it has 2.5 million members and grew bookings by 103% year over year. It exited 2025 with a bookings run rate of $1.1 billion. The business was operating cash flow positive.

"Our raise brings together the world's most sophisticated investors, leading health institutions, and iconic global athletes behind the mission to unlock human performance and healthspan," Ahmed said.

Whoop, founded by Ahmed in 2012, offers a high-performance fitness wearable designed to provide deep insights into physical recovery, sleep, and strain by monitoring physiological data 24/7.

Unlike traditional smart watches such as the Apple (AAPL) Watch, the screenless Whoop device focuses on collecting data rather than notifications. Its latest innovations include the launch of Whoop 5.0 and Whoop MG.

The new Whoop MG model notably received FDA clearance for medical-grade ECG and blood pressure monitoring, marking a significant shift toward clinical health integration. Additionally, the platform continues to leverage its Whoop Coach AI to provide personalized training recommendations based on the user's specific data.

Whoop's business model is subscription-based. The strap itself is included at no up-front cost with a membership. As of early 2026, the pricing for a standard annual membership is $239.

On potential future product launches, Ahmed said, "We're always evaluating sensing from every location on the body. We're looking at a lot of different capabilities beyond even what I think is traditionally thought of as health sensing."
