Elon Musk confirmed on X what many have suspected for weeks: xAI is being dissolved as a standalone company. Grok, the data infrastructure, and the entire AI team will be folded into SpaceX under the new ‘SpaceXAI’ label. It’s the end of one of the most ambitious — and short-lived — AI startups in recent memory.
From AI Challenger to GPU Landlord
The backstory makes this particularly striking. Just three months ago, in February 2026, SpaceX acquired xAI in an all-stock deal valued at $250 billion. Now the company is being effectively dismantled. And what’s happening with the massive Colossus 1 data center in Memphis, Tennessee? SpaceX is renting out its entire computing capacity — over 220,000 Nvidia GPUs — to Anthropic.
TechCrunch nailed it: xAI has become a ‘neocloud’. A company that buys GPUs and rents them out rather than using them to train its own frontier models. For a company that set out to compete with OpenAI and Anthropic, that’s a dramatic strategy reversal.
Every Co-Founder Has Left
What makes the picture even clearer: every co-founder except Musk himself has now left xAI. Reports suggest that employees were internally using other AI models instead of Grok, which triggered a restructuring and further layoffs. Grok, the chatbot product, never really gained traction outside of X — especially not in the enterprise space.
The SpaceX IPO Is Driving This
The timing isn’t coincidental. SpaceX is preparing its IPO, reportedly targeting a $1.75 trillion valuation. A functioning GPU rental business with paying customers like Anthropic looks far better in an IPO prospectus than a money-losing AI lab that can’t keep up with the competition.
Sean O’Kane from TechCrunch’s Equity podcast put it bluntly: this looks like a ‘major heat check before the IPO.’ A neocloud might be a more believable business in the short term, but it’s not the kind of story that gets outside investors excited about long-term innovation.
My Take
The irony is hard to miss. Musk co-founded OpenAI, then broke away, founded xAI to compete — and is now renting his GPUs to Anthropic, the company founded by former OpenAI researchers. The circle closes, just probably not the way Musk imagined.
For Anthropic, the deal is a windfall: 300 megawatts of additional compute capacity, available immediately, exactly when demand is through the roof. For xAI — or SpaceXAI, as it’s now called — it’s an admission that they can no longer keep up in the AI race.
