These figures were shared by KRAFTON — the parent company of Unknown Worlds, the studio that developed Subnautica 2. They thanked gamers for their strong interest in the underwater adventure and assured that they are listening to feedback for further improvement of the project.

Subnautica 2 is selling very rapidly. Let us recall, the game surpassed the 1 million copies mark in the first few hours after release, and after 12 hours, its sales exceeded 2 million copies.

According to estimates by Alinea Analytics, Subnautica 2 is currently the fastest-selling new release of 2026 on Steam. They assert that Subnautica 2 outpaced Slay the Spire 2 by 1.4 times and Crimson Desert by three times in sales speed on the platform.

Incidentally, Alinea Analytics believes that nearly all of Subnautica 2's sales were on Steam. Their calculations show Xbox console owners purchased only around 100,000 copies of the game. They do not provide figures for the Epic Games Store, where Subnautica 2 is also available, but they note that with Game Pass subscription, the title's total audience is about 6.5 million people. Analysts estimate Subnautica 2’s revenue to be over 100 million dollars.

Subnautica 2 was released in early access on PC and Xbox Series on May 14, 2026. The date for the full release of the game is still unknown.
