SpaceX has committed $2 billion to artificial intelligence company xAI, as per the Wall Street Journal, marking one of the largest investments in the sector this year and deepening the integration of billionaire Elon Musk’s business empire. The funding, part of a broader $5 billion equity round, comes as xAI accelerates its efforts to challenge the dominance of OpenAI in the rapidly evolving artificial intelligence landscape.
The investment follows a merger between xAI and X, the social media platform formerly known as Twitter, creating a combined entity now valued at $113 billion, according to people familiar with the matter. The deal underscores Musk’s strategy of weaving together his technology ventures—ranging from space launch services to social media and electric vehicles—through a shared artificial intelligence backbone.
A key element of this integration is Grok, xAI’s flagship chatbot, which has already been deployed to handle customer support for Starlink, SpaceX’s satellite internet service. The company is also exploring the use of Grok’s advanced language and reasoning capabilities in Tesla’s Optimus robots, with the aim of enabling more sophisticated human-machine interactions and autonomous operations.
Industry analysts say the move positions xAI to leverage data and infrastructure from across Musk’s companies, potentially giving it an edge in developing and deploying large-scale artificial intelligence models. The merger and fresh capital injection are expected to support xAI’s continued investment in model training and infrastructure, as the company seeks to close the gap with established rivals.
Despite recent controversies over Grok’s outputs, Musk has described the chatbot as “the smartest artificial intelligence in the world.” Neither SpaceX nor xAI responded to requests for comment on the reported deal. The sizable investment highlights Musk’s ambition to create a vertically integrated artificial intelligence ecosystem spanning space, automotive, and digital platforms.
