Investors eye Oura and Whoop as potential IPOs, each backed by high valuations that mirror early fitness‑tracker hype. Oura sells a $400 smart ring that has crossed Wall Street, Silicon Valley, and celebrity circles, while Whoop’s screen‑less wristband hooks millions into a subscription model. Both firms recently raised capital at $10‑$11 billion in late 2023 round.

Unit sales illustrate traction: Oura has shipped over 5.5 million rings, ranking third in U.S. wearable volume behind Apple and Google, per IDC data. Whoop counts more than 2.5 million members worldwide. Yet the Fitbit precedent warns of slowing growth when single‑purpose devices cede ground to all‑in‑one smartwatches since its acquisition by Google in 2021 for just $2.1 billion.

Both companies aim for public markets, but their lofty multiples—around ten times revenue—raise doubts. A decade after Fitbit’s IPO, its valuation stalled and Google bought it for $2.1 billion, less than twice revenue. Investors face a similar risk: high early hype may not translate into sustainable profitability for long term growth in the wearable sector today.

The wearable boom delivers genuine insights—from menstrual‑cycle prediction to granular sleep analysis—and builds strong user loyalty. Yet the market’s past teaches that rapid growth can stall when technology converges with mainstream smartwatches. Firms like Oura and Whoop must therefore prove that subscription revenue can scale beyond the initial hype to justify their current valuations today.
