History of World Labs, Inc.
World Labs was founded in April 2024 and raised two financing rounds within months. An initial round valued the company near $200 million, and a second round led by New Enterprise Associates pushed the valuation past $1 billion by August 2024.
The company emerged from stealth on September 13, 2024, announcing $230 million in total funding. Andreessen Horowitz, NEA, and Radical Ventures co-led the round, joined by AMD Ventures, Intel Capital, NVentures, Adobe Ventures, Marc Benioff, Ashton Kutcher, and Databricks Ventures. AMD's investment foreshadowed the acquisition two years later.
World Labs spent 2025 building its first product. Marble, its flagship large world model, launched in November 2025, letting users generate explorable 3D environments from text and image prompts. The product drew attention from game studios, simulation developers, and robotics teams.
In September 2026, AMD acquired World Labs for approximately $8.2 billion. Fei-Fei Li joined AMD as chief scientist, one of the most prominent academic appointments at a chip company. The deal was part of AMD's broader push to build an AI software stack to compete with NVIDIA's ecosystem.
