Seagate seeks major Bloomington wafer fab expansion
Seagate has filed plans for a 64,500-square-foot, two-story expansion at its Bloomington wafer-fabrication campus at 7801 Computer Ave. S. and 7850 Nord Ave. S., nearly tripling production space for HAMR technology.[1]
The Bloomington Planning Commission will hold a public hearing on the plan this week, and city staff are recommending approval.[1] The addition would nearly triple wafer-fabrication space to about 30,000 square feet and focus on heat-assisted magnetic recording, or HAMR, technology.[1] The plan would eliminate 148 parking spaces but leave 1,118, and a city parking study projects peak use of roughly 818 vehicles.[1]
In June 2020, Seagate announced plans to consolidate its Minnesota operations at the Bloomington campus and sell the roughly 400,000-square-foot Shakopee facility.[1] That Shakopee property was sold in December 2023 in a $36 million sale-leaseback.[1] Seagate completed a two-story expansion at Bloomington in 2022.[1] The company has since ramped commercial shipments of its Mozaic HAMR drives to hyperscalers and reported $9 billion in revenue for 2025.[1]
Seagate's Normandale campus, which spans Bloomington and Edina, covers roughly 700,000 square feet as of 2026.
The mainstream summary does not mention the significant role that AI-driven demand is playing in Seagate's expansion plans. According to Seagate's Decarbonizing Data report, 94.5% of respondents indicated increasing storage needs due to AI, with global data volume projected to triple between 2023 and 2028. This surge in demand is a critical factor driving the need for expansions like the one at the Bloomington wafer fab to support HAMR technology, which is designed for higher areal density. Additionally, a McKinsey analysis highlights that the semiconductor industry has experienced explosive growth due to AI, with record sales and projections indicating that the demand for AI-related chips is a primary driver behind this trend. These insights suggest that the expansion is not merely a local operational decision but part of a broader response to a rapidly evolving technological landscape that the mainstream summary overlooks.
Furthermore, while the summary provides details about the physical expansion and parking adjustments, it fails to contextualize the strategic importance of Seagate's Normandale campus, which produces approximately 20% of the company's data-storage disk heads. This operational capacity underscores how critical the Bloomington facility is to Seagate's overall production and innovation strategy in an increasingly competitive market fueled by AI advancements.[2][3]
