Microsoft and Meta Lead March 2026 Data Center Expansion with Combined $23B in New Projects
Microsoft secured approvals for 15 data centers in Wisconsin valued at over $13 billion and expanded North Carolina capacity to 4.5 GW, while Meta broke ground on a $10 billion, 1 GW campus in Indiana. The announcements highlight continued hyperscale investment despite industry-wide construction capacity declining 5.5% from 2024.
Key Points
- Microsoft approved for 15 data centers at former Foxconn site in Mount Pleasant, Wisconsin, exceeding $13 billion investment [1][2]
- Meta's $10 billion Lebanon, Indiana campus marks company's largest infrastructure project to date with 1 GW capacity [1]
- January 2026 saw record $25.2 billion in US data center construction starts across 20 projects [2]
- Global expansion continues with $6.3 billion Hyundai project in South Korea and Kazakhstan's planned 1 GW campus [1]
- Under-construction capacity dropped to 5,994.4 MW, down 5.5% from 2024, amid power and permitting delays [4]
The data center industry maintained its breakneck expansion pace in March 2026, with Microsoft and Meta announcing transformative projects totaling over $23 billion in combined investment [1][2]. These developments come as January 2026 marked a record $25.2 billion in US construction starts [2], even as industry observers note growing challenges with power availability and permitting delays reducing overall construction capacity [4].
Microsoft Expands Midwest and Southeast Footprint
Microsoft's aggressive expansion strategy crystallized with the approval of 15 new data centers at the former Foxconn site in Mount Pleasant, Wisconsin, representing a construction value exceeding $13 billion [1][2]. The technology giant simultaneously secured a power deal with Duke Energy for large-scale complexes in North Carolina, bringing its total contracted capacity in the region to 4.5 GW [1][2]. These developments underscore Microsoft's commitment to distributed cloud infrastructure as AI workloads continue to surge.
Meta Sets Indiana Infrastructure Record
Meta broke ground on its second Indiana data center campus in Lebanon, located 30 miles northwest of Indianapolis, with the 1 GW facility valued at $10 billion—marking the company's largest infrastructure project to date [1]. The development is expected to create 4,000 peak construction jobs and 300 operational positions [1], providing significant economic impact to the region while expanding Meta's AI and cloud computing capabilities.
Global Expansion Accelerates
International data center development maintained robust momentum with several major announcements. Hyundai Motor Group committed $6.3 billion to an innovation hub in Gunsan City, South Korea, incorporating an AI data center alongside robotics manufacturing and renewable energy generation [1]. The Kazakhstan government announced plans for Central Asia's largest data center campus in Ekibastuz with up to 1 GW energy capacity [1]. Additionally, OpenAI, Samsung SDS, and SK Telecom will begin construction in March 2026 on South Korean facilities with initial 20 MW capacity, according to Science Minister Bae Kyung-hoon [1].
Regional US Development Surge
Beyond the headline projects, significant regional developments emerged across the United States. AVAIO Digital Partners launched a multi-phase campus in Little Rock, Arkansas, with an initial $6 billion investment and projected power demand up to 1 GW [1]. NTT secured four new US leases totaling 115 MW [3], while Nebius received tax breaks for an 800 MW campus in Independence, Missouri [3]. A $5 billion project is in development in the Columbus, Georgia area [3], and Penzance targeted a 600 MW campus in West Virginia [3].
Construction Trends and Challenges
January 2026's record $25.2 billion in construction starts concentrated heavily on the East Coast ($12.2 billion from New York to South Carolina) and Midwest ($12.2 billion from Minnesota to Ohio) [2]. The Southeast led activity due to favorable power availability and regulatory environments [2]. However, Pat Lynch of CBRE noted the industry shift toward 100+ acre greenfield campuses requiring increased municipal partnerships, while power and permitting delays reduced under-construction capacity to 5,994.4 MW, down 5.5% from 2024 [4].
Market Dynamics Signal Industry Evolution
The March 2026 announcements reveal a data center industry at an inflection point, balancing unprecedented demand with increasing infrastructure constraints [1][2][4]. Microsoft and Meta's combined $23 billion commitment demonstrates hyperscaler confidence in long-term AI and cloud growth [1], yet the 5.5% decline in under-construction capacity signals emerging bottlenecks [4]. The geographic distribution of new projects—spanning from Wisconsin to North Carolina, Arkansas to Missouri—reflects a strategic diversification away from traditional hubs as operators seek available power and favorable regulatory environments [2]. The international expansion, particularly in Asia-Pacific markets, indicates a global race for AI infrastructure supremacy [1].
Infrastructure Constraints Shape Future Growth
The data center sector appears poised for continued expansion despite mounting challenges. With OpenAI, Samsung SDS, and SK Telecom beginning construction this month [1], and multiple billion-dollar projects in various stages of development [1][3], investment momentum remains strong. However, the industry must navigate increasingly complex power procurement, as evidenced by Microsoft's strategic Duke Energy partnership [1][2], and address permitting delays that are constraining construction capacity [4]. Success will likely depend on operators' ability to secure reliable power sources and forge productive relationships with local governments and utilities.
