Saudi-Based Humain Leads $900M Series C Round for Luma AI

US-based start-up Luma AI, focused on generative video and visual-content platforms, announced a $900 million Series C funding round, led by Saudi Arabia’s HUMAIN, backed by its sovereign capital base. This funding puts Luma’s valuation at around $4 billion, marking one of the largest recent raises in the video-generation and creative-AI sector.

Existing US investors such as Andreessen Horowitz (a16z), Amplify Partners and Matrix Partners also participated, aligning US venture capital with Middle East capital flows in the AI sector.

Luma­AI develops advanced “world-models” that extend beyond text-based large-language models. Its models aim to generate, understand and operate on multimodal data—from videos and images to audio and physical-world simulations. The new funding will fuel infrastructure growth, model development and commercial deployment.

HUMAIN is building a multigigawatt AI-supercluster in Saudi Arabia, and Luma AI’s collaboration positions it as both a technology partner and front-runner in deploying models for entertainment, advertising, simulation and creative workflows. The round reflects growing regional interest in frontier AI and signals a shift in global creative-tech funding dynamics.
