Luma AI CEO Amit jain (L), and HUMAIN CEO Tareq Amin at the Saudi Investment Forum in Washington on 19 November 2025Luma AI, the California-based frontier AI company building multimodal “world models,” has raised $900 million in Series C funding led by HUMAIN, a subsidiary of Saudi Arabia’s Public Investment Fund (PIF). The announcement was made during the U.S. – Saudi Investment Forum in Washington, D.C.
Luma AI said the funding will accelerate its mission to build advanced AI systems capable of understanding and generating video, audio, imagery and language.
CEO Amit Jain stated, “HUMAIN is the perfect partner for this next stage in Luma AI’s explosive trajectory… To create AI that can help humanity in the physical world and expand our understanding of the universe, we need to build systems that can learn from a quadrillion tokens of information ‑ roughly the collective digital memory of humanity ‑ contained in video, image, audio, and language. HUMAIN is deploying frontier compute infrastructure at impressive speed, and this is critical to achieving Luma AI’s mission. We are also partnering deeply across customized models, go‑to‑market, and deployment of frontier capabilities to build a full end‑to‑end value‑chain for multimodal AI.”

As part of the deal, Luma will become a primary customer of HUMAIN’s forthcoming Project Halo, a 2-gigawatt AI supercluster being developed in Saudi Arabia. The cluster is positioned as one of the world’s largest compute infrastructure projects and will support the training of Luma’s next‑generation multimodal models.
HUMAIN CEO Tareq Amin highlighted the strategic depth of the collaboration, saying, “This investment underscores an important point in HUMAIN’s philosophy: we are not only funding the next wave of AI, we’re building the full value chain that makes it possible. Luma AI is an exceptional U.S.‑based global frontier startup pushing the boundaries of multimodal world models. Their technical ambition, research velocity, and proven ability to turn foundational breakthroughs into real products make them uniquely aligned with HUMAIN’s vision. Our investment in Luma AI, combined with HUMAIN’s 2 GW supercluster, positions us to train, deploy, and scale multimodal intelligence at a frontier level. This partnership sets a new benchmark for how capital, compute, and capability come together.”
The company added that achieving its vision requires extremely tight integration between compute, systems engineering and algorithms.
“It is only through this level of systems and algorithmic integration that it is possible to build models that can understand and simulate the universe.” the company said in a statement
Luma AI’s flagship model Ray3 is already being used across entertainment, gaming, advertising and design. With the new investment, Luma expects to expand into robotics, simulation and enterprise applications.
The round also included participation from AMD Ventures, Andreessen Horowitz, Amplify Partners and Matrix Partners.
The collaboration also includes HUMAIN Create, a program focused on developing AI models trained on Arabic and regional datasets to support culturally aligned intelligence for enterprises and governments across the Middle East.
Saudi Arabia’s growing investments in large‑scale compute and digital infrastructure continue to strengthen its positioning as a global AI hub. The Project Halo supercluster, powered by renewable energy, is expected to accelerate both regional and international AI innovation.
