Musk’s friends have commented over the years on the fact the billionaire is basically homeless.

The world’s richest man admitted that he does not own a home and sleeps on the couches of friends.

Elon Musk remarked in a video interview with Chris Anderson, the president of conference organizers TED, broadcast Monday, “I don’t even own a property right now, I’m literally sleeping at friends’ places.”

“If I travel to the Bay Area, which is where most of Tesla’s engineering is, I basically rotate through friends’ spare bedrooms,” Musk added.

According to Bloomberg, Musk has a net worth of $251 billion.

He was responding to Anderson’s comment that many people are offended by the concept of billionaires because of global wealth disparities. Senator Elizabeth Warren, for example, has chastised billionaires like Musk for their comparatively low tax bills.

“For sure, it would be very problematic if I was spending billions of dollars a year in personal consumption, but that is not the case,” Musk told Anderson, adding that he doesn’t own a yacht or really take vacations, though he famously does have a personal jet.

“It’s not like my own use is excessive. “I mean, the plane is an exception, but if I don’t use the jet, I have fewer hours to work,” he admitted, recognizing that his net worth was “bonkers.””

Musk’s comments look like his first confirmation that he doesn’t have a permanent home, despite being the world’s richest person.

The billionaire’s friends have commented over the years on his thrifty habits.

In the prerecorded interview, Anderson asked how upset Musk was with comments about him and other billionaires as being too wealthy.

“I mean, at this point, it’s water off a duck’s back,” Musk said.
