About Stack Infrastructure
Stack Infrastructure's business model targets wholesale customers exclusively, primarily hyperscale operators and AI/ML focused enterprises seeking carrier neutral infrastructure. This specialization contrasts with the broader enterprise and colocation diversification of larger operators, creating both strategic focus and customer concentration risk. The wholesale concentration aligns the company's economic interests directly with the accelerating capital expenditure cycles of major cloud providers and AI infrastructure developers. Carrier neutrality in the portfolio ensures the company serves as a flexible infrastructure foundation rather than competing with customer networks, a positioning that strengthens long-term customer relationships in increasingly competitive wholesale markets.
The operator's trajectory reflects the current market dynamics favoring specialized wholesale competitors with strong private equity backing. Northern Virginia's capacity density and Phoenix's power efficiency showcase disciplined capital allocation toward markets with constrained supply. European operations, while modest by capacity measures, position Stack for potential expansion as APAC demand patterns mature and European markets absorb distributed AI workloads. Against the backdrop of slowing hyperscale growth in certain regions and intensifying competition from larger diversified operators, Stack Infrastructure's focused wholesale model and geographic specificity represent viable differentiation, though future growth will depend on maintaining customer concentration while diversifying into emerging geographies where competing capacity remains structurally limited.
STACK Infrastructure is a data center company that develops and operates hyperscale data centers, powered shells, and colocation facilities for hyperscale and enterprise clients.

Recent Activity
Amazon announces $6B Louisiana data center expansion to $18B total investment
Amazon announced a $6 billion expansion of its northwest Louisiana data center project, bringing total planned investment to $18 billion. The expansion includes a third data center campus at Resilient Technology Park in Shreveport, extending across Caddo and Bossier parishes. The project is expected to create 210 direct jobs and 499 indirect jobs in the region, with all three campuses supporting up to 750 direct jobs total. This expansion comes less than six months after Amazon announced its initial $12 billion investment in February 2026.
Hayward rewrites data center rules after STACK approval
Hayward, California approved a 310,000-square-foot hyperscale data center by STACK Infrastructure with 76.6 MW capacity in May 2025 without City Council review. Facing community pushback over environmental and resource concerns, the city subsequently established new zoning regulations requiring data center projects larger than 50 MW to receive public hearings and City Council approval. The facility is projected to generate $8.3-10.5 million annually in tax revenue while raising concerns about water and energy resource consumption during California's drought.
Stack Infrastructure data center project in Hesse, Germany canceled
