As global tensions continue to rise, one doomsday bunker builder says a surprising group is increasingly preparing for the worst: conservative Christians who believe the world may be approaching the biblical “end times.”

Ron Hubbard, CEO of Texas-based Atlas Survival Shelters, says his company is experiencing unprecedented demand, with roughly 50 bunkers currently under construction. While celebrities, billionaires and governments continue investing in underground shelters, Hubbard told The U.S. Sun that many ordinary Christian families are now joining them.

“In the U.S., demand is strong too, especially among conservative Christians,” Hubbard said. “Many believe we’re in the ‘end times’ or approaching them. They think this generation could see World War III and the Rapture, and they want to protect their families during that period.”

According to Hubbard, the interest represents a significant shift. Many of his newest customers have never considered owning a survival shelter before.

“A lot of people never thought about it before,” he said. “But now, it’s all they can think about.”

Atlas Survival Shelters builds underground structures ranging from basic $25,000 steel shelters to luxury bunkers starting around $500,000. High-end versions can include bedrooms, kitchens, medical facilities, independent power systems, water supplies, entertainment rooms and even shooting ranges. Some are built beneath newly constructed homes and hidden behind secret entrances, serving as wine cellars or home theaters during everyday life before becoming emergency shelters if needed.

Hubbard estimates demand for his company’s bunkers has increased by roughly 500 percent over the past decade, with spikes typically following wars, political unrest or other major global crises.

The company has also become well known for its celebrity clientele. Hubbard said Atlas has worked with or designed shelters connected to Kim Kardashian, YouTube star MrBeast, Meta founder Mark Zuckerberg, and influencers Andrew and Tristan Tate.

While the celebrity connections often generate headlines, Hubbard believes today’s broader demand reflects growing uncertainty about the future.

For many Christians, however, discussions about preparedness are often balanced by biblical teaching about trusting God. Scripture encourages believers to exercise wisdom while ultimately placing their confidence in the Lord rather than in earthly security.

Jesus warned His followers that wars, rumors of wars and global turmoil would occur before His return, but He also cautioned believers not to be consumed by fear. In Matthew 24, He instructed His disciples, “See that you are not alarmed,” reminding them that such events are part of a larger prophetic timeline.

Likewise, Psalm 20:7 declares, “Some trust in chariots and some in horses, but we trust in the name of the Lord our God.”

The recent surge in bunker construction highlights how anxiety about global instability is affecting people from every walk of life. Wealthy buyers are increasingly requesting homes capable of operating independently during prolonged emergencies, complete with secure communications, medical facilities and backup infrastructure.

Naomi Corbi, directing partner at security company SAFE, said today’s elite clients are pursuing more than survival.

“The real status symbol is not excess anymore, it’s continuity,” Corbi said. “The ability to keep living, operating, and making decisions when everyone else is waiting for systems to come back online.”

Whether motivated by geopolitical fears, natural disasters or biblical expectations, preparedness has become a growing conversation. For Christians, though, many pastors emphasize that while practical planning has its place, the believer’s ultimate hope lies not in underground shelters but in God’s sovereignty and the promise of Christ’s return.
