A pair of low-slung industrial buildings on Christy Street in Fremont, home to electronics heavyweight Sanmina and liquid-cooling upstart DeepCoolAI, quietly traded hands this winter for just under $93 million. The 253,500-square-foot complex, built in 1991, changed owners late last year, according to public filings, in a deal that underscores how industrial sites tied to advanced manufacturing and AI infrastructure have become some of the Bay Area’s hottest real estate.
As reported by The Mercury News, county records filed on Dec. 24, 2025, list the properties at 42701 and 42735 Christy St. The filings show an affiliate of New York-based real estate firm Tishman Speyer as the buyer at just under $93 million, with an affiliate of BlackRock recorded as the seller. The transaction was officially logged in Alameda County records late last month.
Who Is Working Inside These Buildings
Sanmina identifies 42735 Christy Street as its Fremont manufacturing plant, where it handles metal fabrication, painting and precision machining, according to Sanmina. DeepCoolAI, a Fremont-based firm that builds liquid-cooling systems for AI data centers and has announced strategic partnerships in the area, is also operating on the site, as detailed by Data Center Frontier.
Investors Zero In On Fremont Industrials
Investors have been shifting capital toward industrial and advanced manufacturing properties in San Jose and Fremont as the office and hotel sectors cool, according to The Mercury News. Developers have started new industrial campuses in Fremont’s Bayside area, and brokers are flagging faster leasing for manufacturing and AI infrastructure tenants, trends chronicled by The Real Deal.
What This Deal Could Mean For Fremont
When a new landlord steps in on a site like this, it often sets the stage for fresh capital improvements, from bulked-up power and upgraded HVAC to specialized buildouts tailored for higher-density computing and electronics production. Market reports and broker commentary indicate buyers are willing to bankroll those upgrades to secure long-term tenants, giving local manufacturers more room to grow, according to research and deal coverage from Colliers.
For Fremont, the sale is another reminder that the city continues to function as a key hardware manufacturing hub and a crucial link in the supply chain behind AI and other high-tech sectors. County filings show the transaction was recorded on Dec. 24, 2025, and any moves Tishman Speyer makes on the property will be closely watched by local businesses and economic development officials.
