HUMAIN invests $3 billion in xAI Series E round
Investment converted to SpaceX shares following February acquisition
#SaudiArabia #funding – Saudi Arabia Public Investment Fund-owned AI company HUMAIN has revealed an investment of $3 billion in Elon Musk’s artificial intelligence company xAI’s Series E financing round, with the transaction preceding xAI’s acquisition by US aerospace manufacturer SpaceX in early February 2026. HUMAIN became a significant minority shareholder in xAI through the Series E transaction, with its holdings subsequently converted into SpaceX shares following the merger, positioning the Saudi company for long-term equity participation in the combined technology platform. The investment builds on HUMAIN and xAI’s 500MW AI infrastructure partnership in Saudi Arabia announced at the US-Saudi Investment Forum in November 2025.
SO WHAT? – The investment positions HUMAIN as both a strategic development partner and scaled global investor in frontier AI. The investment was made at a platform-scale inflection point, with xAI’s advanced AI capabilities integrated into SpaceX’s engineering depth, infrastructure and scale through what represents perhaps one of the most consequential technology mergers in recent history. By participating in xAI’s final financing round ahead of the merger, HUMAIN secured exposure to long-term equity upside in a combined entity uniquely positioned for accelerated growth and deep technological integration.
Here are some key points about this announcement:
HUMAIN has revealed an investment of $3 billion in Elon Musk’s artificial intelligence company xAI’s Series E financing round, with the transaction preceding xAI’s acquisition by US aerospace manufacturer SpaceX in early February 2026.
The transaction represents a significant end-to-end capital deployment for HUMAIN, reflecting continued momentum in its long-term investment strategy focused on category-defining technology platforms across artificial intelligence and frontier technologies.
HUMAIN’s participation in the Series E round reinforces its role as a scaled, long-term strategic investor capable of supporting companies across multiple stages of growth.
The investment builds on HUMAIN and xAI’s 500MW AI infrastructure partnership in Saudi Arabia announced at the US-Saudi Investment Forum in November 2025, under which the companies committed to jointly develop next-generation AI data centre and compute infrastructure and deploy xAI’s Grok models in the Kingdom
The combination of xAI’s advanced artificial intelligence capabilities with SpaceX’s scale, infrastructure and mission-driven engineering creates a uniquely positioned platform for accelerated growth, deep technological integration and long-term value creation following the early February acquisition.
HUMAIN’s strategy includes pursuit of additional investments across artificial intelligence, frontier technologies and critical infrastructure where long-term vision, technical excellence and execution converge beyond the xAI transaction.
As a Public Investment Fund company, HUMAIN delivers full-stack AI capabilities globally across four core areas: next-generation data centres, hyper-performance infrastructure and cloud platforms, advanced AI models including Arabic large language models, and transformative AI solutions for public and private sectors.
ZOOM OUT – The $3 billion investment follows HUMAIN and xAI's landmark framework agreement announced at the US-Saudi Investment Forum in November 2025, under which the companies committed to jointly develop a network of world-class GPU data centres anchored by a flagship 500MW facility set to become one of the most advanced AI compute hubs globally. The partnership will be xAI's first large-scale compute deployment outside the United States, combining HUMAIN's low-cost value proposition in infrastructure design, construction and operations with xAI's leadership in frontier AI systems and large-scale compute optimisation. Beyond infrastructure, the collaboration includes HUMAIN’s commitment to deploy xAI's Grok models throughout Saudi Arabia, with integration into HUMAIN's agent platform HUMAIN ONE.
