Elon Musk's xAI startup disclosed a $1.46 billion net loss for the third quarter of 2025, up from $1 billion earlier in the year, while outlining ambitions to develop AI for powering Tesla's Optimus humanoid robots. The company burned through $7.8 billion in cash over the first nine months, supported by over $40 billion in equity funding. This development raises questions in ongoing shareholder lawsuits accusing Musk of breaching fiduciary duties at Tesla.
Elon Musk's artificial intelligence company, xAI, revealed significant financial strain in its latest quarterly results, reporting a net loss of $1.46 billion for the period ending September 30, 2025. This marked an increase from the $1 billion loss in the first quarter, with the firm spending $7.8 billion in cash during the first nine months of the year on data centers, talent, and AI software development. Despite the losses, revenue nearly doubled to $107 million in the third quarter, driven by demand for AI products, though the company may fall short of its $500 million annual target, having recorded over $200 million through September.
xAI executives informed investors of their goal to create self-sufficient AI systems to power humanoid robots, specifically mentioning Tesla's Optimus, designed to perform human tasks. Chief Revenue Officer Jon Shulkin emphasized the focus on rapidly building AI agents and software, which will feed into "Macrohard," Musk's term for an AI-only software company. This plan contradicts Musk's earlier statements that Tesla would develop the Optimus robot's brain independently, without needing to license from xAI. He had said: "Tesla has learned a lot from discussions with engineers at xAI that have helped accelerate achieving unsupervised FSD, but there is no need to license anything from xAI."
The announcement comes amid shareholder lawsuits alleging Musk breached fiduciary duties by diverting Tesla resources to xAI, including AI talent and Nvidia chips. Plaintiffs argue xAI competes directly with Tesla's AI efforts. xAI, valued at $230 billion after a $20 billion funding round involving Nvidia and Qatar Investment Authority, is expanding infrastructure with the Colossus data center in Memphis, Tennessee, and a new $20 billion facility in Southaven, Mississippi, set to start operations in February 2026. These moves highlight xAI's aggressive push toward "escape velocity" in AI development, burning nearly $1 billion monthly while integrating with Musk's ecosystem, including Grok chatbot in X and Tesla vehicles.
