Our note
Worth knowing.
Our note: The $4 billion figure is called an "estimated valuation" by Calcalist. Anthropic talks: Bloomberg, 2026-09-08, https://news.bloomberglaw.com/mergers-and-acquisitions/anthropic-said-to-walk-away-from-6-billion-decart-acquisition. Dates for Lucy 2 and Oasis 3 come from the dates of press articles (Forbes 2026-01-27, TechCrunch 2026-06-10) that Decart's own site links; Decart's pages do not show dates. Decart also sells chip-switching/inference software, not only world models.
