United States-based artificial generative intelligence (AGI) start-up Luma AI has secured USD 900 million in a Series C funding round led by HUMAIN, an AI firm owned by Saudi Arabia’s Public Investment Fund (PIF), and joined by AMD Ventures, along with existing investors Andreessen Horowitz, Amplify Partners, and Matrix Partners.
The capital and compute infrastructure will accelerate Luma AI’s path towards building a multimodal AGI model – AI that can generate, understand, and operate in the physical world. HUMAIN’s joint venture with AMD, Cisco and Luma AI will see the rollout of a mega data centre with 1GW AI infrastructure by 2030 in the Kingdom.
Luma AI said the new funding, which was announced during the US-Saudi Investment Forum, will accelerate its plans to build products in HUMAIN that understand and simulate reality for robotics, entertainment, advertising, gaming, and personalised education. The start-up will become a customer of HUMAIN, which is building “Project Halo,” a two-gigawatt AI supercluster in the Kingdom for training world models and developing culturally aligned AI for the MENA (Middle East and North Africa) region.
HUMAIN was at the centre of a series of partnerships announced during Saudi Crown Prince Mohammad bin Salman Al Saud’s visit to Washington. This also included a partnership with Elon Musk’s xAI, where the two companies signed a framework agreement to build low-cost GPU data centres in the Gulf region.
A Groq deal also saw HUMAIN agree to triple Saudi Arabia’s Groq-powered inference capacity. HUMAIN and Global AI will also develop high-density AI data centres in the United States featuring NVIDIA infrastructure. During his meeting with US President Donald Trump, the Saudi Crown Prince pledged to increase the Kingdom’s investments in the world’s largest economy to USD 1 trillion from the USD 600 billion announced when the Republican visited Saudi Arabia in May 2025.
