Elon Musk may be the world’s richest person, but he says his current home is an Airstream trailer parked at xAI’s data center site in Memphis, Tennessee.
Musk said he has temporarily moved to the construction site to personally oversee the expansion of xAI’s enormous computing infrastructure, continuing a habit established during some of the most demanding periods at Tesla and Twitter.
“I am living in an Airstream trailer at the data center,” Musk said during a recent interview cited by Fortune, explaining that he wanted to remain physically close to the project as work accelerates.
The unusual living arrangement comes as xAI races to build increasingly powerful computing clusters needed to train and operate its Grok artificial intelligence models.
Musk Moves Into Trailer at xAI Site
The Memphis complex has become central to xAI’s effort to compete with OpenAI, Anthropic and other frontier AI developers.
Musk launched xAI in 2023 and has since pushed the company to build infrastructure at extraordinary speed. Its Colossus supercomputer in Memphis was initially assembled with around 100,000 Nvidia GPUs in just a few months, and the company has continued expanding its computing capacity.
The latest development phase is significantly larger, requiring extensive construction, power infrastructure and thousands of AI accelerators.
Musk’s decision to live at the site reflects his long-standing management philosophy that executives should remain physically close to the most important operational bottlenecks.
For most chief executives, that might mean frequent site visits. For Musk, it has repeatedly meant sleeping at work.
Musk Previously Slept at Tesla and Twitter
During Tesla’s difficult Model 3 production ramp, Musk famously slept on the floor of the company’s Fremont factory while attempting to resolve manufacturing problems.
The period became known inside Tesla as “production hell,” as the automaker struggled to transform the Model 3 from a promising electric vehicle into a mass-produced product.
Musk later adopted a similar approach after acquiring Twitter in 2022.
During the chaotic restructuring that followed the $44 billion acquisition, Musk said he occasionally slept at Twitter’s San Francisco headquarters. He has repeatedly argued that being present during periods of intense operational pressure helps accelerate decision-making.
Now he is applying the same philosophy to artificial intelligence.
xAI Is Racing to Expand Computing Capacity
The stakes in Memphis are substantial because access to computing power has become one of the most important competitive advantages in the AI industry.
Frontier models require enormous clusters of advanced GPUs, vast amounts of electricity and sophisticated cooling and networking infrastructure.
xAI is attempting to expand faster than competitors that have spent years developing their cloud infrastructure relationships.
That urgency has made Memphis one of Musk’s highest-priority projects.
The company is building out additional data center capacity as it develops increasingly powerful generations of Grok and seeks to compete directly with models from OpenAI, Anthropic and Google.
Musk’s wealth makes the trailer arrangement particularly striking. Fortune estimates his fortune at approximately $917 billion, meaning one of the wealthiest individuals in history is voluntarily living at an industrial construction site while overseeing the project.
AI Infrastructure Becomes Musk’s Latest ‘Production Hell’
The circumstances differ from Tesla’s Model 3 crisis, but the underlying strategy is familiar.
Musk has repeatedly concentrated his personal attention on whichever project he considers the biggest constraint on one of his companies’ growth.
At Tesla, the bottleneck was vehicle manufacturing. At Twitter, it was restructuring the company after an enormous acquisition.
At xAI, the constraint is computing infrastructure.
The race to develop more powerful AI models increasingly depends on how quickly companies can secure chips, electricity and data center capacity. For xAI, completing its Memphis expansion could determine how effectively it competes with substantially more established rivals.
Musk’s decision to live in an Airstream at the site is therefore more than an eccentric billionaire lifestyle story.
It is another example of the management approach that has followed him across companies for decades: when Musk believes a project is entering a critical phase, he moves as close to the problem as possible – sometimes literally sleeping beside it.
