Luma AI, a leading artificial intelligence company, has successfully closed a $900 million Series C funding round, spearheaded by Humain, a Saudi Public Investment Fund (PIF) company. The significant investment, announced on November 19, 2025, in Washington D.C., is earmarked to accelerate Luma AI's pursuit of Multimodal Artificial General Intelligence (AGI) and the development of "World Models" capable of understanding and simulating the physical universe. A key component of this initiative is the construction of Project Halo, a 2-gigawatt AI supercluster in Saudi Arabia, which Luma AI will utilize for its advanced training needs.
The funding round saw substantial participation from AMD Ventures, alongside existing investors Andreessen Horowitz, Amplify Partners, and Matrix Partners, valuing Luma AI at over $4 billion. This capital injection underscores a growing trend of large-scale investments in the AI sector, particularly for companies focused on foundational models and infrastructure.
Central to Luma AI's expansion is its partnership with Humain for Project Halo, described as one of the world's largest compute infrastructure buildouts. This 2-gigawatt supercluster in Saudi Arabia will enable Luma AI to train its models on peta-scale multimodal data, vastly exceeding the data capacity of current large language models. "For AI to be able to help humans in the physical world, we need systems that can understand and simulate the universe," Luma AI CEO Amit Jain stated in a recent social media post, highlighting the necessity of such infrastructure.
Luma AI's mission is to develop AI systems that transcend traditional large language models by learning from humanity's digital footprint across video, audio, and language. The company aims to build products that "understand and simulate reality" for diverse applications including robotics, entertainment, advertising, gaming, and personalized education. Its flagship model, Ray3, has already demonstrated capabilities in generative video, with Jain noting its performance benchmarks against competitors.
This strategic partnership also aligns with Saudi Arabia's broader vision to become a global AI hub, with Humain deploying full-stack AI solutions and focusing on initiatives like HUMAIN Create, which aims to build sovereign AI models and products for the Arabic world. Humain CEO Tareq Amin emphasized, "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." The collaboration is expected to foster innovation and expand Luma AI's leadership into simulation, design, and robotics.
