In times of uncertainty, the average person might watch a meditation video or stock up on canned goods. The wealthiest among us, however, might turn to a luxury underground bunker instead.
“When a war breaks out, or when America bombs Iran, it does cause a spike in our business,” Ron Hubbard, founder and CEO of Atlas Survival Shelters, told Business Insider in July.
This month, Hubbard said he saw a “big spike” in interest from individuals in the Middle East, and especially the UAE, after the US and Israel attacked Iran on February 28. He said he also saw a moderate business bump in the US for a typical client request: a place to protect their family.
Larry Hall, the owner of luxury bunker company Survival Condo, told Business Insider back in July that he’s seen increased interest during geopolitical conflicts.
Hubbard said it’s safe to assume most billionaires have some form of shelter, though relatively few have extremely extravagant bunkers costing tens of millions of dollars. Hall said he’s built a bunker complex with a swimming pool, and others have included a shooting range or bowling alley. Over the summer, he said he was negotiating bunker sales between $1 million and $2 million.
As Hall sees it, bunkers have become a “new status symbol of the elite” in the post-pandemic era, and are no longer as taboo as they used to be.
The interiors of Atlas Survival Shelter bunkers can include wine cellars and televisions.

The rapid growth of AI has also given rise to new doomsday scenarios beyond war. After a top Anthropic AI researcher quit his job and warned that AI labs are “gambling with our lives,” Geoffrey Hinton, the Godfather of AI, said in a BBC interview that it’s “not unreasonable” to deduce that there is a 10% chance AI would wipe out humanity in a decade.
Many tech CEOs has openly offered their (p)doom number, namely, the chances of AI bringing about ruin for human civilization.
Dario Amodei, the Anthropic CEO, previously told Liron Shapira, the host of “Doom Debates,” in 2023 that he estimates the chances of something going “quite catastrophically wrong” with AI at 10% to 25%. Elon Musk, the xAI CEO, set his p(doom) number at 20% after releasing Grok-4 in 2025, adding in an xAI livestream that he has “somewhat reconciled myself to the fact that even if it wasn’t going to be good, I’d at least like to be alive to see it happen.”

Some of the country’s biggest tech names have hopped on the prepper trend in the last decade, buying underground shelters and collections of guns.
LinkedIn cofounder Reid Hoffman told the New Yorker in 2017 that he thinks more than half of his Silicon Valley billionaire peers have bought some sort of end-of-world hideout.
Here are some of the tech millionaires and billionaires who have invested in doomsday planning.
Bunkers — or similar tunnels or shelters
Meta CEO Mark Zuckerberg hasn’t confirmed reports that he has a survival bunker, but said on an episode of the podcast “This Past Weekend w/ Theo Von” in 2025 that he has an “underground tunnel” at his ranch in Hawaii.
In 2023, Wired reported that Zuckerberg was building a 5,000-square-foot underground shelter at the ranch. A year later, local news outlet Hawaii News Now reported that county planning documents included a “storm shelter” measuring almost 4,500 square feet. Wired reported in July 2025 that, according to planning documents, Zuckerberg bought 962 acres of land across from the existing compound and added more buildings.
The Meta CEO downplayed the initial bunker reports during an interview with Bloomberg in December, comparing the space to “a basement.”
“There’s just a bunch of storage space and like, I don’t know, whatever you want to call it, a hurricane shelter or whatever,” he said. “I think it got blown out of proportion as if the whole ranch was some kind of Doomsday bunker, which is just not true.”
A representative for Zuckerberg directed BI to his comments to Bloomberg.
OpenAI CEO Sam Altman has also denied having a bunker, saying instead that he has “reinforced basements” when Von, the podcaster, asked whether he had a hideout.
“I have underground, concrete, heavy, reinforced basements, but I don’t have anything I would call a…” Altman started to say, before Von cut him off, laughing and saying that it sounded like a bunker. Von described a bunker as “a place you could hide when it all goes off,” and Altman repeated that he didn’t yet have what he would consider a bunker.
“But it has been on my mind, not because of AI, but just because people are dropping bombs in the world again,” Altman said.
He didn’t share details of his existing “structures” at a WSJ Tech Live event in 2023, either, but did note that none of them would be helpful if artificial intelligence “goes wrong.” He also told the New Yorker in 2016 that he has a plot of land in Big Sur, California, that he could fly to if necessary.
PayPal cofounder Peter Thiel attempted to build a 10-bedroom compound in New Zealand, but the local government rejected his plans after environmentalists complained. Some suspected that parts of the estate were intended as a doomsday bunker.
Hall told Business Insider that he’s been “flabbergasted” by some of the reported shelter locations, since California and New Zealand are near active tectonic plate boundaries.
“They’re the two places you don’t want to be building bunkers, and yet allegedly these billionaires are building in those two places,” he said.
Representatives for Altman and Thiel did not respond to Business Insider’s request for comment.
The Cybertruck and life on Mars

The CEO of Tesla and SpaceX is perhaps less focused on preparing for doomsday on Earth.
Musk has long floated the idea of making humans a “multi-planetary species” by colonizing Mars to safeguard the future of human civilization should Earth come to an end. Through his space company, Musk said in 2020 that he plans to send 1 million people to Mars by 2050 by launching three Starship rockets every day and creating job opportunities on Mars. The SpaceX board has also pledged to grant $1 billion in SpaceX shares if Musk can create a colony of 1 million humans on the red planet.
Physicists have called Musk’s plan both challenging and unrealistic, but the trillionaire’s concern about the apocalypse spills over into his other companies. Tesla’s Cybertruck, with its unusually smooth steel body, sharp edges, and heavy weight, is famously dubbed by Musk as being “apocalypse-proof.”
“Sometimes you get these late-civilization vibes,” Musk said at the Cybertruck launch in 2023. “The apocalypse could come along at any moment, and here at Tesla, we have the finest in apocalypse technology.”
The Cybertruck has since faced at least five recalls, and drivers have reported issues with the $70,000 vehicle in snow and sand.
Other preparations include guns and eye surgery
Some opt for different doomsday preparations. Altman also previously told the New Yorker that he has “guns, gold, potassium iodide, antibiotics, batteries, water, gas masks from the Israeli Defense Force.”
Reddit CEO Steve Huffman told the New Yorker he’s bought guns, ammo, and motorcycles. And he’s taken it one step further — he said that in 2015, he got laser eye surgery to hopefully better his chances of survival.
Interest in doomsday-esque materials doesn’t just extend to those who are preparing for the end of the world.
Palmer Luckey, the founder of Oculus and Anduril, hasn’t referred to himself as a prepper, but he owns a sizable collection of older military-grade vehicles. He said on an episode of Bloomberg’s “The Circuit” that he also owns decommissioned missile silos, some of which extend underground, where he stores what he says is the world’s largest video game collection.
“I put that in one of my missile bases, 200 feet underground,” Luckey told Bloomberg’s Emily Chang. Representatives for Luckey and Huffman did not respond to a request for comment from Business Insider.
Hall said that he thinks the association with prominent tech leaders has helped his business.
“A lot of people like to live vicariously through what other people do,” he said.
