Oura's upcoming IPO is set to raise $2.2 billion, but the offering is primarily a liquidity event for early backers rather than a growth capital raise. According to the latest filing, Forerunner Ventures intends to sell its entire stake in the smart-ring maker, valued at as much as $1.26 billion.

That means a significant portion of the proceeds will go to existing shareholders. Forerunner's exit alone accounts for more than half of the total IPO value, underscoring how the deal is structured to reward early investors.

The company itself may see limited new funding from the listing, which could raise questions about its future capital needs. Still, the IPO marks a milestone for Oura as it enters public markets.
