What is SoftBank's Ohio AI data center campus? SoftBank's Ohio AI data center campus is the PORTS Technology Campus, a $500 billion, 10-gigawatt AI data center complex being built on the site of a former uranium enrichment plant near Piketon, Ohio, making it the largest construction project ever announced in the United States. On March 20, 2026, SoftBank CEO Masayoshi Son broke ground alongside U.S. Commerce Secretary Howard Lutnick and Energy Secretary Chris Wright, signaling a new era in AI infrastructure development with direct implications for commercial real estate investors nationwide.

Key Takeaways
- SoftBank is investing $500 billion to build a 10-gigawatt AI data center campus in Pike County, Ohio, the largest single construction project in U.S. history.
- The project will create 35,000 construction jobs at peak and 2,500 permanent operations roles, transforming the regional economy of southern Ohio.
- A $33 billion natural gas power plant generating 9.2 gigawatts will power the campus, representing one of the largest private energy investments ever.
- The campus sits on a former federal uranium enrichment site, establishing a model for brownfield redevelopment of decommissioned government facilities.
- Local opposition is already mobilizing, with Ohio residents filing a petition for a constitutional ban on mega data centers.
Why the SoftBank AI Data Center in Ohio Matters for CRE
The sheer scale of this project has no precedent in American commercial real estate. At 10 gigawatts of planned capacity, the PORTS Technology Campus would consume roughly the equivalent of 10 million homes' worth of electricity. For context, the entire Northern Virginia data center corridor, the largest concentration of data centers on Earth, currently operates at approximately 4.5 gigawatts combined. SoftBank is building more than double that in a single Ohio campus.
Commerce Secretary Howard Lutnick called it "the largest construction project in the country." The project is part of a broader $550 billion Japanese investment commitment to the U.S., negotiated as part of trade deal discussions with the Trump administration. The Bloomberg report confirmed the campus will be built in phases, with Phase 1 delivering 800 megawatts by early 2028 and full deployment by 2030.
The PORTS Technology Campus: Key Details for Investors
The development is being built on the former Portsmouth Gaseous Diffusion Plant, a Cold War era facility where uranium was enriched for decades. The site's existing industrial infrastructure, including grid connections and large cleared acreage, makes it uniquely suited for hyperscale data center development. Here is what CRE investors need to know about the project specifics:
- Total investment: $500 billion over the life of the project
- Power capacity: 10 gigawatts at full buildout
- Power source: $33 billion in natural gas generation (9.2 GW) distributed across the region
- Grid upgrades: $4.2 billion investment by SB Energy and AEP Ohio in transmission infrastructure
- Construction workforce: 35,000 workers at peak, with Phase 1 starting mid-2026
- Permanent jobs: Approximately 2,500 once operational
- Consortium partners: 12 Japanese firms (SoftBank, Toshiba, Hitachi, Mizuho, Sumitomo Mitsui) and 9 U.S. firms including Goldman Sachs
CRE Investment Implications: Five Angles to Watch
1. Regional Economic Transformation
Pike County, Ohio, has a population of roughly 27,000. The arrival of 35,000 construction workers, followed by thousands of permanent employees and supply chain workers, will create extraordinary demand for housing, retail, hospitality, and services. CRE investors should watch for multifamily development opportunities, workforce housing demand, and retail leasing activity in the broader southern Ohio corridor. When a project of this magnitude lands in a rural area, property values within a 30-mile radius typically see significant appreciation as infrastructure investment flows in.
2. Power Infrastructure as a CRE Constraint
The $33 billion natural gas plant and $4.2 billion grid upgrade underscore a reality Morgan Stanley recently highlighted: power availability is now the primary constraint on AI data center development. For CRE investors evaluating data center opportunities, proximity to available power has become more important than proximity to population centers. The fact that SoftBank chose rural Ohio over established data center markets like Northern Virginia or Dallas speaks volumes about where capacity exists.
3. Brownfield Redevelopment Model
The decision to build on a former federal uranium enrichment site establishes a potentially transformative model for CRE developers. The United States has hundreds of decommissioned military and industrial sites with existing grid connections, road access, and cleared acreage. If the PORTS campus succeeds, expect a wave of similar conversions. CRE investors with holdings near decommissioned federal facilities may see unexpected demand for adjacent parcels.
4. Community Opposition and Regulatory Risk
Even before construction begins, local residents have filed a petition to place a constitutional ban on mega data centers on the Ohio statewide ballot. This follows a national pattern: as we reported in our analysis of $64 billion in blocked data center projects, community opposition has become a material risk factor for data center investments. CRE investors evaluating data center exposure must factor in entitlement risk, community relations costs, and the possibility of regulatory moratoria.
5. Supply Chain and Construction Sector Impact
A single project requiring 35,000 construction workers will strain labor markets across the Midwest. The data center construction boom is already creating what the Associated Builders and Contractors trade group estimates will be a need for 500,000 new workers by 2027. For CRE investors in industrial and logistics properties, this translates to increased demand for building materials storage, equipment yards, and temporary worker housing. The liquid cooling requirements of next-generation AI chips add another layer of specialized construction demand.
How This Fits the Broader AI Data Center Landscape
SoftBank's Ohio campus joins a growing roster of hyperscale AI infrastructure projects reshaping American commercial real estate. The four major hyperscalers, Alphabet, Microsoft, Meta, and Amazon, are committing nearly $700 billion in combined capital expenditure this year alone. Meta has committed $600 billion to AI infrastructure through 2028, including its Hyperion campus in Louisiana. Microsoft has deployed hundreds of thousands of liquid-cooled GPUs across Azure data centers globally.
What makes the SoftBank project distinct is the consortium model. By partnering 12 Japanese and 9 American firms under the Portsmouth Consortium, SoftBank is distributing financial risk while leveraging cross-border trade relationships. For CRE investors, this signals that the next wave of data center development may increasingly involve international capital partnerships rather than single-company buildouts. If you are evaluating data center investment opportunities and need personalized guidance, The AI Consulting Network specializes in helping CRE professionals navigate exactly this landscape.
What This Means for Cap Rates and Valuations
Data center cap rates have compressed significantly over the past 18 months, with institutional-quality facilities trading at 4.5% to 5.5% in primary markets. The SoftBank Ohio campus will likely accelerate cap rate compression further by validating that even secondary and tertiary markets can support hyperscale development when power infrastructure exists. CRE investors should expect:
- Land value increases near power-rich sites with grid capacity, even in rural areas
- NOI growth for existing data center operators as demand continues to outstrip supply
- New asset classes emerging around data center campuses, including workforce housing, logistics hubs, and power generation facilities
- DSCR improvement for data center loans as institutional lenders gain confidence in long-term AI infrastructure demand

Frequently Asked Questions
Q: How large is SoftBank's Ohio AI data center compared to other projects?
A: At 10 gigawatts of planned capacity, SoftBank's PORTS Technology Campus would be the largest data center campus in the world. For comparison, the entire Northern Virginia data center corridor, currently the world's largest concentration of data centers, operates at roughly 4.5 gigawatts combined. The $500 billion total investment dwarfs any single commercial real estate project in U.S. history.
Q: When will the SoftBank Ohio data center be operational?
A: Phase 1 construction is expected to begin mid-2026, delivering approximately 800 megawatts of capacity by early 2028. Full 10-gigawatt buildout is targeted for the end of the decade, around 2030. CRE investors should expect regional economic impacts to begin well before the campus is fully operational, as construction activity alone will drive significant demand.
Q: Why did SoftBank choose Ohio instead of an established data center market?
A: The former Portsmouth Gaseous Diffusion Plant offered three critical advantages: existing grid connections from decades of industrial use, large cleared acreage suitable for hyperscale development, and available power generation capacity. Established markets like Northern Virginia and London are increasingly power-constrained, pushing developers to secondary locations where energy infrastructure can be built from the ground up.
Q: What are the risks for CRE investors in the data center sector?
A: Key risks include community opposition (Ohio residents have already filed a petition for a constitutional ban on mega data centers), power cost escalation, construction labor shortages, and the possibility that AI compute demand growth slows. Norway's $2.1 trillion sovereign wealth fund recently warned that the AI infrastructure buildout could create a bubble if demand fails to match supply. CRE investors should diversify data center exposure and conduct thorough due diligence on power contracts and entitlement status.
Q: How does the SoftBank project affect nearby property values?
A: Projects of this scale typically drive significant appreciation in surrounding areas due to infrastructure investment, job creation, and economic activity. However, properties immediately adjacent to large data center campuses can face negative externalities including noise, heat output (research from Arizona State University found data centers warming neighboring communities by several degrees), and visual impact. CRE investors should evaluate specific parcels carefully based on proximity and use case.
