Elon Musk’s artificial intelligence startup xAI has secured a $2 billion investment from SpaceX as part of a $5 billion equity round, according to The Wall Street Journal. The funding deepens the integration between Musk’s ventures, as xAI intensifies its race against rivals like OpenAI and Anthropic.
The investment comes on the heels of xAI’s merger with Musk’s social platform X (formerly Twitter), pushing the company’s valuation to $113 billion. This strategic move reinforces Musk’s long-term vision of aligning AI development across his business ecosystem, which includes SpaceX, Tesla, and X.
The AI chatbot Grok, developed by xAI, now powers customer support for Starlink, SpaceX’s satellite internet service. It is also being considered for future deployment in Tesla’s humanoid robot project, Optimus. Despite recent backlash over Grok’s controversial responses, Musk maintains it is "the smartest AI in the world."
xAI is aggressively expanding its AI infrastructure, investing heavily in model training and compute capabilities. The company aims to build safe, advanced AI systems capable of reasoning and interacting with the world across digital and physical platforms. Industry watchers see xAI as a serious contender in the rapidly evolving AI landscape, particularly with Musk’s push for integration across his high-impact enterprises.
Neither SpaceX nor xAI have responded to media requests for comment. Still, this multi-billion dollar investment underscores the growing convergence of AI, aerospace, robotics, and social media under Musk’s vision—and signals intensifying competition in the global AI arms race.
