Elon Musk said Monday that he was living in an Airstream trailer in Memphis while xAI pushed ahead with its expansion of Colossus, the compute-heavy project the company started building in 2024. He said the trailer was parked just steps from the site and called it his new “palace.”
The comment came during a taping of the All-In podcast and helps explain why people are searching for the Elon Musk Memphis Airstream trailer now: Musk was not talking about a distant corporate plan, but about where he was sleeping while the work was underway. Gwynne Shotwell said he was in Memphis helping build buildings, a plain description that fits the pace of the project better than any polished corporate line.
xAI has been racing to expand Colossus in Memphis, where the build has become a centerpiece of Musk’s artificial intelligence push. The first version of Colossus reportedly took 122 days to put together, and in late July xAI said it would add a fourth data center called Minihard. The company says Colossus was built to provide compute for Grok, and the scale of the effort has made Memphis the center of xAI’s infrastructure buildout on Earth.
What Musk did not say is almost as revealing as what he did. He did not identify which Airstream model he was using, even though some campers can fit a sleeping area, kitchen and bathroom into a 16-foot space. That leaves the picture clear enough for journalism and fuzzy enough for Musk: a billionaire with access to luxury travel and properties choosing to stay close to the worksite anyway.
It is not the first time he has done that. In the 1990s, Musk and Kimbal slept in a tiny Palo Alto office for six months while showering at the YMCA. He later slept under his desk most nights while preparing to launch X.com in 1999, stayed at Michael Marks’s home while traveling in Silicon Valley in 2007, and said during the Tesla production rush in 2017 and 2018 that he and others were getting four or five hours of sleep, often on the floor. After buying Twitter in 2022, he said he claimed a couch in Twitter’s seventh-floor library.
The pattern suggests the Memphis setup is not a stunt so much as a familiar Musk habit: stay near the pressure point until the pressure eases. The question now is not whether he can camp beside the build, but how long he intends to keep doing it as xAI pushes to finish the next phase of Colossus.
