Subnautica 2 Generates $139.2 Million on Steam, Ranks Among 2026’s Top New Releases

Subnautica 2 has generated an estimated $139.2 million in gross revenue on Steam, placing it among the six highest-grossing new releases of 2026, according to the latest market analysis from Alinea Analytics. The figure puts the survival sequel ahead of Meccha Chameleon and behind Slay the Spire 2 in the firm’s ranking of new games released this year.

Alinea Analytics market analysis lead Rhys Elliott published the figures on September 3 while examining Steam’s broader financial performance. Importantly, the $139.2 million figure is an estimated gross revenue figure, rather than an official revenue number announced by Unknown Worlds or publisher Krafton.

The game also entered Xbox Game Pass alongside its Steam Early Access launch.
