A Dead Mall in Downtown San Francisco Might Become an AI Data Center
A shuttered landmark gets an unlikely second-life pitch
The target is one wing: 350,000 square feet of ex-Bloomingdale's
KG is not bidding for the whole mall. Its inquiry covers roughly 350,000 square feet at 845 Market Street, the former Bloomingdale's space making up about one-third of the larger complex. CEO Jared Krieger told the Chronicle the model "is a conversion that keeps the ground floor and the public-facing levels of the building active and open, with the technical use in the upper floors and back-of-house space." He said the firm is working with an undisclosed buyer and "a known AI Lab."
A mystery buyer, a mystery lab, and a rooftop garden
Krieger described the concept as "an AI-controlled living space" developed with the lab partner, adding that its "proprietary AI design can utilize resources, such as dedicating water to a rooftop garden." That garden's output would go to a food-security nonprofit. Beyond those lines, almost everything material is undisclosed: the buyer's identity, the lab's identity, financing, power capacity, water use, and the prospective operator.

Forty years of retail ends in foreclosure and a January shutdown
A 45-day freeze just stopped every new data center in its tracks
KG's feeler landed just as City Hall hit the brakes. The Board of Supervisors unanimously approved a 45-day moratorium on new and expanded data centers in early October, and Mayor Daniel Lurie signed it on October 16. During the pause the Planning Department must study energy, water, air quality, land use and community impacts and draft long-term controls; the freeze can be extended for up to 22 months. The Planning Director told Supervisor Shamann Walton that the city has approved only two new data centers since 2001; market trackers count at least six.
Lurie's downtown vision leaves little room for server farms
Lurie has said he wants a downtown where people can work, live, play and learn, and a data center between Market and Mission streets strikes many as the opposite of that vision. NBC Bay Area reported pushback from the mayor's office. Still, the Chronicle quoted two City Hall and real estate sources as saying officials could be receptive to a plan that keeps the ground floor active: "There is an interest in just making something work."
Two projects are already frozen, and Oakland hit pause too
One retail bright spot: Nordstrom Rack is coming back
Nordstrom announced in mid-October that its off-price banner Rack will return downtown in fall 2027 with a 51,500-square-foot, four-story store at 2 Stockton Street near Union Square. The return signals individual retailers still see a future downtown.
What decides it: a buyer, a permit path, and the freeze clock
For now the mall-to-data-center story is only an inquiry email: unnamed buyer, unnamed lab, no application, no financing or energy numbers. Three things decide what happens next: whether the roughly $40 million Bloomingdale's-wing deal closes and who stands behind it; what permanent rules the Planning Department writes once the 45-day freeze lapses, and any extension toward 22 months; and whether KG's mixed public-plus-technical reuse can win over a City Hall that wants foot traffic, not server racks, on Market Street. Until then it is a test of downtown's hardest question: if the shoppers won't come back, will the servers move in?
