The Cold War Silo Real Estate Market Nobody Is Covering

The U.S. government quietly sold off its nuclear weapons infrastructure to private citizens over 60 years, and the secondary market that formed is now pricing these assets into the millions.

Somewhere beneath the rolling wheat fields of central Kansas, a concrete cylinder drops 18 stories into the earth. Its walls are nine feet thick. Its blast doors weigh 47 tons. For four years in the early 1960s, it housed an Atlas F intercontinental ballistic missile tipped with a nuclear warhead 250 times more powerful than the bomb dropped on Hiroshima. Today it is listed on Zillow for $1.3 million, described by its listing agent, realtor Terra Martin, as an insane property that is very much off the grid. The equivalent construction cost in today's dollars is approximately $190 million. The current asking price is not a typo.

Finite Supply, Rising Prices

The supply of decommissioned ICBM silos is fixed and historically documented. The U.S. Army Corps of Engineers built 72 Atlas F silos across the country in the early 1960s, plus 72 Atlas E sites, plus 54 Titan II complexes, the latter ringing three Air Force bases in groups of 18. Most were decommissioned by the mid-1960s, rendered obsolete almost immediately by faster, better successor systems. The Titan IIs lasted longer, operational until 1984 when President Reagan's Strategic Forces Improvement Plan retired the last of them.

When the silos went out of service, the government typically demolished what it could, backfilled shafts with concrete and debris, and sold the land. The General Services Administration conducted those liquidations over decades, and the prices reflect an era when nobody wanted them: early buyers paid as little as $40,000 to $300,000 for properties the government had spent $200 million or more constructing. Ed Peden, a history teacher from Topeka, Kansas, toured his future Atlas silo in 1982 by canoe and flashlight because the underground levels had flooded. He bought it anyway. John Robinson, a realty specialist in the GSA's Fort Worth office, later told a reporter that he received hundreds of calls a year from prospective missile base buyers, most of them interested in secure storage. Others, he noted, wanted to grow mushrooms.

That era of government liquidation is substantially over. What remains is a secondary market: silos trading between private parties, at prices that have climbed from mid-five-figures into seven-figure territory as a new buyer class has formed around what the real estate industry has taken to calling doomsday chic.

The Properties in Circulation

The active listings in 2025 tell the story plainly. Near Sprague, Washington, 34 miles west of Spokane, an Atlas E silo built in the 1950s for the 567th Strategic Missile Squadron sits on 24.5 acres and is listed at $1.45 million on Zillow. It has 12,946 square feet of underground space, a working elevator, blast doors rated to withstand a 1-megaton airburst from 1.6 miles away, and a residential zoning classification. The previous owner, David McIntyre, lived in it for 30 years. His daughter listed it when he passed. Inquiries have come in from energy developers, cryptocurrency investors, scientists, and mushroom farmers.

In Lincoln, Kansas, the Atlas F that went viral in September 2025 is listed at $1.3 million for 8.5 acres and 2,500 square feet of refurbished underground space, its control room and living quarters freshly painted. The retired Air Force colonel John Gilbert, a senior science fellow at the Center for Arms Control and Non-Proliferation who served in a similar Kansas facility in the 1960s, described the original working conditions as isolated and noisy, with things that tended to smell bad. The current listing copy focuses on the James Bond ambience.

In southern Arizona, near Tucson, a Titan II complex listed at $395,000 sold above asking price in cash after receiving 30 to 40 calls per day in its first week on the market. Realtor Grant Hampton, who handled the sale, said he had never seen anything like it. He has since been contacted by owners of silos in Arkansas and Kansas asking for consulting help. Unfortunately, he told the Arizona Daily Star, there is not enough inventory to make a career out of selling silos.

That constraint is exactly what is driving prices. The total addressable market is estimated at 150 to 180 properties still in private circulation. The supply cannot expand. The demand, driven by geopolitical anxiety and a demographic shift in who wants these properties, is growing.

The Buyer Class Has Changed

The original buyers of decommissioned silos in the 1970s and 1980s were largely salvagers stripping copper wiring and steel, followed by survivalists who saw the hardened structures as practical refuges. Neither group had much money to spend. The current buyers are different in almost every measurable way.

LinkedIn co-founder Reid Hoffman told The New Yorker in 2017 that more than half of his Silicon Valley billionaire peers had purchased some form of end-of-world hideout. The characterization has stuck, and the demographics at the retail silo level have followed the same general arc. The Washington State Atlas E drew interest from cryptocurrency investors. The Nebraska Atlas F converted into a residence attracted attention from rental investors and data storage firms. Realtor Mike Figueroa, who listed a converted Atlas F in York, Nebraska, told Realtor.com: at first we thought it would be survivalists and preppers who would be interested in it, but now we are seeing people interested in it as a specialty property. Potential buyers proposed using it as a campsite, a movie set, an outdoor storage facility, and a diving training facility, the last because the silo sits above 140 feet of groundwater.

Larry Hall, the developer who has done more than anyone to create the market's luxury tier, describes his buyers as ultra-high-net-worth people: scientists, entrepreneurs, doctors, and real estate executives. He told The Daily Beast in May 2026 that the level of inquiries more than doubled after the Iran war started, and was already elevated from the Russia-Ukraine conflict. Before COVID, everyone asked whether they would ever really need it, Hall said. After COVID, no one asked that question.

The Survival Condo and the Luxury Tier

Hall bought his first Atlas F silo, at Raven Ridge near Concordia, Kansas, in 2008 for $300,000 after learning the government was auctioning off decommissioned Cold War weapons sites. He had built data center infrastructure for defense contractors including Northrop Grumman, and after September 11 pivoted to shelters for the wealthy. The Survival Condo Project converted the silo into a 15-story luxury underground condominium running 200 feet below the surface. Residents enter through 16-ton blast doors guarded by armed security, then descend into units with nine-foot ceilings and access to a subterranean swimming pool, saunas, a movie theater, a dog park, digital windows showing high-definition feeds of the surface, a shooting range, hydroponic gardens, and a five-year supply of freeze-dried food per person. Monthly condo fees run approximately $2,600. Units range from 920 square feet at $1.5 million to full-floor penthouse configurations at $4.5 million. The first complex sold out entirely. A second is under construction nearby, projected to cost $50 to $60 million, with a waiting list.

The market above the Survival Condo is now corporate. In February 2025, Semafor reported that Hall had priced an underground data center with executive suite space to a cryptocurrency firm for $64 million. The cheapest version of such a facility, featuring 11 floors of living quarters and four floors of data center space, was quoted at $45 million. Survival Condo was tracking eight companies in the planning stages of underground bunker construction, three of them competing to purchase an existing 150,000-square-foot facility in Kansas originally started by a big oil billionaire who died before it was completed.

The Market Logic

The structural argument for silo real estate is straightforward: finite, hardened assets with irreplaceable construction specifications, appreciating from government disposal prices into seven-figure secondary market territory, while the underlying anxiety driving demand shows no sign of retreating.

The construction economics reinforce the pricing. One analysis found that replicating the Washington State Atlas E in 2025 would cost between $6.1 million and $8.8 million, counting excavation, reinforced concrete, blast doors, elevator, HVAC, and air filtration systems. The nine-foot-thick concrete walls and 47-ton blast doors cannot be mass-produced. The government built these structures on a wartime timeline with a wartime budget, and neither condition applies to private construction today. A buyer paying $1.45 million for the Sprague, Washington silo is, on one reading, acquiring an $8 million replacement asset at a steep discount. No mortgage bank will finance it, so every upper-tier transaction closes in cash. That constraint limits the buyer pool while also confirming something about its composition: these are transactions where liquidity is not the binding constraint.

What the market lacks, still, is systematic coverage. Every silo that sells generates a local news cycle treating the property as a curiosity. Nobody has mapped the inventory as an asset class, traced the price appreciation curve across decades and types, or documented the quiet shift from salvage value to investment thesis. The Zillow listing exists. The buyer profile exists. The price trajectory exists. The journalism, as a coherent market narrative, does not.

The assets are real. They have been trading for 60 years, from the GSA's Fort Worth realty office to Zillow. The question is not whether this is a market. The question is why it took this long for anyone to notice.
