Musk Shuts Down Tesla-xAI Merger Talk, Focuses on Cross-Company AI Integration

Elon Musk has flatly rejected the idea of merging Tesla with his artificial intelligence startup, xAI. Responding directly to speculation circulating among investors on X, Musk said simply: “No.”

This comes just a day after he floated the possibility of Tesla shareholders voting on whether the automaker should invest in xAI, a change that could increase ties between the two companies without formally merging them. 

“It would be great if Tesla could invest,” he noted earlier, but stressed that shareholder approval would be necessary.

Despite the speculation, Tesla and xAI have yet to issue official statements addressing the merger rumours or clarifying their future relationship.

xAI, Musk’s AI startup behind the controversial Grok chatbot, has grown aggressively since its $33 billion acquisition of X (formerly Twitter) in March 2025. 

That acquisition placed the combined group’s valuation at $80 billion, but sources told Reuters that xAI had discussed valuations as high as $200 billion in its latest funding talks. 

Whether those numbers show the company’s real market potential is still uncertain, as Musk has publicly downplayed suggestions of a fresh capital raise: “We have plenty of capital.”

What is apparent, however, is that xAI is positioning itself as the AI backbone of Musk’s expanding industrial network. Its Grok chatbot has already been deployed in Starlink’s customer support operations, with integration into Tesla’s Optimus robots also on the horizon.

On X, Grok facilitates real-time interactions, further tightening the web of Musk-owned enterprises.

In July 2025, xAI raised $10 billion, half through equity led by Morgan Stanley and half through debt financing. Notably, SpaceX, another Musk company, contributed $2 billion to this round, marking its first known external investment into xAI. 

Reports from The Wall Street Journal indicated that SpaceX’s involvement was part of a $5 billion equity round. 

Operationally, xAI is pushing infrastructure goals. Its Memphis-based supercomputer, Colossus, already runs on over 200,000 GPUs, with plans to scale to one million. The firm is targeting $1 billion in revenue by the end of 2025 and forecasts $19 billion by 2029, supported by an $18 billion investment into its compute backbone.

Despite its commercial momentum, Grok stumbled in July when it produced antisemitic and offensive content, triggering a public apology and a promised codebase review. Still, Musk stands by the chatbot, calling it “the smartest AI in the world” and promising deeper integration across his companies.

From a governance standpoint, merging Tesla, a publicly traded company, with xAI, which remains private, could ignite regulatory challenges. Musk’s current strategy appears to favour operational integration over corporate consolidation. 

Embedding Grok into Tesla vehicles, Optimus robots, and Starlink services could offer the benefits of synergy without the legal complexities of a merger.

For now, Musk says Tesla will not merge with xAI. But as history shows, in Musk’s empire, “no” today doesn’t always mean “never.”
