Luma AI Raises $900 Million Series C Led by HUMAIN And Partners on 2 Gigawatt AI Supercluster in Saudi Arabia

HUMAIN led $900M Series C funding for Luma AI, enabling a 2GW AI supercluster in Saudi Arabia to advance multimodal AI and regional Arabic models, said CEO Tareq Amin.

  • On Nov. 19, 2025, Luma AI announced a $900 million Series C led by HUMAIN, with AMD Ventures and Andreessen Horowitz participating at the U.S.-Saudi Investment Forum, Washington, D.C.
  • HUMAIN, launched in May, was formed as a Public Investment Fund of Saudi Arabia-backed effort to build a $10 billion venture fund and create a full AI value chain, HUMAIN said.
  • Technical briefs from Luma explain its Ray3 and Dream Machine require peta-scale data and vast compute to train multimodal world models from video, audio, and images.
  • Luma will move significant infrastructure as HUMAIN builds Project Halo, a 2-gigawatt AI supercluster in Saudi Arabia, granting Luma access to Saudi data centers and a Riyadh office.
  • Amid the Crown Prince's Washington visit, HUMAIN says Project Halo's first gigawatt is due by 2030 but did not commit to full 2GW timing, while U.S. chip-sale approvals and critics' objections surface.
