Every frozen dinner, every tub of ice cream and every vial of temperature-sensitive medicine spends part of its life inside a building most shoppers never picture: a cold storage warehouse. For nearly two decades this was one of the steadier corners of commercial real estate, a place where demand rarely wobbled. The first half of 2026 interrupted that calm, at least on paper.
According to research from Newmark Group, Inc. (NASDAQ: NMRK), the U.S. cold storage market gave back more space than it filled during the first six months of the year. Tenants vacated roughly 56 million cubic feet while landlords delivered about 41 million cubic feet of new space, and the national vacancy rate climbed to 7.7%. That produced the first negative first-half net absorption since 2007, a stretch long enough that few people working in the sector today have seen anything quite like it.
Look closer, though, and the headline hides a split screen. Buildings finished since 2020 have absorbed almost all of the recent demand, while older properties have been shedding tenants steadily since 2022. By the middle of 2026, these legacy warehouses accounted for 68% of every vacant cubic foot in the country. The vacancy figures tell opposite stories depending on age: about 10.9% for newer space, which reflects fresh buildings still filling up, and roughly 8.2% for legacy stock, which reflects a slower slide into obsolescence. What looks like weakness is closer to a migration, with occupiers trading drafty older boxes for modern ones that offer taller ceilings and stronger power.
Money is pushing those decisions along. Building a cold storage warehouse costs between $130 and $350 per square foot, compared with roughly $85 to $150 for a standard dry warehouse, and average taking rents have more than doubled since 2020 to reach $27.40 per square foot. With numbers like that, developers are leaning toward projects that are spoken for before the concrete cures (build-to-suit, owner-user and pre-leased deals), and some companies are choosing to own their buildings outright rather than rent. A size gap complicates the picture, because the average lease signed since 2020 runs near 125,000 square feet while the average project under construction approaches 300,000 square feet, which leaves big new buildings waiting longer for tenants.
The demand side carries its own tension. In the near term, shoppers are buying fewer grocery units and food inflation remains a risk. Over a longer horizon, the pillars holding up the sector are simply shifting location. Online grocery sales jumped 21.5% year over year in July while in-store sales slipped 2.6%, a sign that more chilled and frozen food is moving through delivery networks that need cold space nearby.
Medicine is the other engine. The rise of GLP-1 treatments for diabetes and weight loss, sold by Eli Lilly and Company (NYSE: LLY) and Novo Nordisk A/S (NYSE: NVO), has been dramatic. Temperature-sensitive biologics, which must stay cold from factory to pharmacy, are expected to grow at an 8.3% annual rate through 2033, drawing billions of dollars into specialized pharmaceutical cold-chain space.
All of this is changing who owns the warehouses. Operators, rather than passive investors, reached a record 36% of the buyer pool, and large landlords such as Americold Realty Trust, Inc. (NYSE: COLD) and Lineage, Inc. (NASDAQ: LINE) sit at the center of a market busy rotating its holdings, selling 1980s-era buildings and buying newer ones. Newmark’s Market Durability Index also points to rising hubs, with Phoenix, Columbus, Kansas City, Nashville, Charleston and Tampa gaining ground on the traditional gateway cities.
The story here is not decline but division. Cold storage is not losing its place in the economy; it is consolidating into taller, better-powered buildings and into faster-growing cities, while the freezers of the 1980s quietly age out of relevance. The companies that read this shift early, and build or buy for where the food and medicine are actually headed, will own the next decade of the cold chain. The rest will be left holding boxes nobody wants to fill.
