Luma AI Raises $900 Million Series C to Power 2GW AI Supercluster in Saudi Arabia

Luma AI, a leading frontier AI company focused on multimodal general intelligence (AGI), has raised $900 million in a Series C funding round led by HUMAIN, a public investment fund (PIF) that delivers global full-stack AI solutions, according to the release. AMD Ventures, Andreessen Horowitz, Amplify Partners, and Matrix Partners also participated in the round. 

The funding will support Luma AI’s partnership with HUMAIN to become a customer of Project Halo, a 2-gigawatt AI supercluster in Saudi Arabia, one of the largest compute infrastructure buildouts in the world. 

The supercluster will enable Luma AI to train and deploy next-generation AI systems capable of understanding and operating in the physical world, going beyond large language models (LLMs) to learn from video, audio, and language data at an unprecedented scale.

“HUMAIN is the perfect partner for this next stage in Luma AI’s explosive trajectory,” said Amit Jain, CEO and co-founder of Luma AI. 

Jain explained that to create AI that can help humanity in the physical world and expand understanding of the universe, it is necessary 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. 

To this, Tareq Amin, CEO of HUMAIN, mentioned that “Our investment in Luma AI, combined with HUMAIN’s 2GW 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 supercluster will support Luma AI in training peta-scale multimodal data, 1,000 to 10,000 times more information than current frontier LLMs, making AI more applicable for real-world tasks. It will also feature next-generation inference systems capable of serving these models globally in real-time.

Luma AI’s flagship model, Ray3, has already demonstrated the company’s ability to transform foundational research into commercial products, deployed across studios, advertising agencies, and brands, including integration within Adobe’s global products. 

With this new round, Luma AI plans to expand into simulation, design, and robotics while maintaining leadership in entertainment and advertising.

The company was also the first to launch models within HUMAIN Create, a regional initiative for building sovereign AI models tailored for the Arabic world. 

These models are designed to understand cultural context, visual nuance, and linguistic diversity, enabling creators, enterprises, and governments to adopt AI solutions that reflect their identity, values, and sovereignty.
