0:07 On Jun 4, 2026 Anthony Gallegos thanked "the more than 4 million people who have purchased Subnautica 2", and the many more who joined through GeForce Now and Xbox Game Pass, whose numbers have not been published.

Some headlines say "2 million on day one"; Unknown Worlds' own words are "within 12 hours". Krafton's second-quarter release called Subnautica 2 one of 2026's best-selling releases worldwide and said it intends to "develop Subnautica into a franchise IP" (Krafton). Krafton's third-quarter figures had not been found for this page as of Nov 4, 2026, so any number above 5 million would be a guess.
