Hyperscale data center campuses in Opportunity Zones

A hyperscale campus is a multi-building site built to deliver hundreds of megawatts (MW) to gigawatts (GW) of IT power for a large cloud or AI company, usually phased over several years. The buildings are designed around the user's power density, cooling and network needs, and the campus often includes its own high-voltage substation.

Scale drives the economics. One hyperscaler request for information sought a site of at least 200 acres with 400 MW available by mid-2027, expandable to 1 GW, or about half an acre per MW at the first phase; that is one request, not a benchmark.⁶ Cushman & Wakefield's 2026 cost guide puts all-in greenfield development at about $8.9 million to $23.3 million per MW, excluding chips and GPUs, so a 400 MW first phase can cost several billion dollars before any servers arrive.⁷

A Qualified Opportunity Zone is a census tract designated under IRC §1400Z-1 in which new investment can earn the tax benefits of §1400Z-2.¹ A hyperscale campus qualifies only if its land and buildings sit inside a designated tract and its owner meets the business tests described below. The broader framework is in Data centers in Opportunity Zones: the complete guide.

The investor gets it, not the tenant. The benefit attaches to capital gains that a taxpayer reinvests as equity in a Qualified Opportunity Fund (QOF), a corporation or partnership that holds at least 90% of its assets in Opportunity Zone property.¹ The fund usually invests through a Qualified Opportunity Zone Business (QOZB), the operating company that owns the campus.

For gains invested after December 31, 2026, the investor defers the gain for up to five years, receives a 10% basis step-up at year five (30% for a rural fund), and can elect to exclude all appreciation on the fund interest after a 10-year hold, with the exclusion capped at fair market value on the 30th anniversary of the investment.¹ The mechanics are in Opportunity Zone tax benefits, explained.

This explains a reported paradox. Microsoft, Meta and Amazon told WIRED in October 2026 that they do not use the program for their data center investments; Google did not respond.⁸ Hyperscalers fund most capital spending from operating cash flow rather than realized capital gains, and the program rewards only reinvested gain. The natural participants are developers, landowners and investors with gains who own the campus and lease it to a hyperscaler. That is an analysis of how the incentive is built, not a statement about any company's tax position.

Models in which the QOZB operates the facility fit best, and a bare single-tenant lease fits worst. The labels below reflect common industry usage, not defined legal terms.

Two other rules shape these structures. First, at least 70% of the tangible property a QOZB owns or leases must be Qualified Opportunity Zone business property, which generally means property bought from an unrelated party that is either first placed in service in the zone by the QOZB or substantially improved.² Second, a hyperscaler that also invests in the fund can become a related party, because the Opportunity Zone rules apply the related-person tests with a more-than-20% ownership threshold in place of the usual more-than-50% (§1400Z-2(e)(2)).¹ Related-party purchases and leases carry extra limits, covered in Related-party rules in Opportunity Zone deals.

Not if it is merely a triple-net lease. The regulations treat owning and operating real property, including leasing it, as a trade or business, but they state that merely entering into a triple-net lease of owned real property is not the active conduct of a trade or business (Treas. Reg. §1.1400Z2(d)-1(d)(5)(ii)(B)).²

A regulatory example finds no active business where a landlord leases an entire building to one tenant on triple-net terms, even though the landlord keeps an on-site office with staff to handle lease issues. A contrasting example finds an active business where on-site employees actively manage and operate the building's non-triple-net space.¹⁰ Commentary on data center deals singles out the single-tenant powered-shell lease to a hyperscaler as the classic risk case, and no authority addresses hyperscale leases directly.⁹

Practical responses include landlord-run critical infrastructure (substations, central cooling plants, security and critical facilities staff), multi-tenant campuses, and turnkey delivery in which the QOZB operates the mechanical and electrical plant. These are practical considerations, not safe harbors. The full analysis is in Powered shell and triple-net data centers in Opportunity Zones.

They fit only with phasing. A QOZB can hold cash as working capital for up to 31 months under a written plan and schedule for acquiring, building or improving zone property, and overlapping or sequential plans can extend that to a maximum of 62 months from the first cash infusion.¹² A delay caused by government action on a completed application can toll the period, but tolling is not automatic.¹²

Power is the long pole. Dominion Energy said in 2024 that connecting data centers above 100 MW in Northern Virginia could take one to three years longer than before, for total waits of up to seven years.¹¹ Vertical construction is faster: Epoch AI's tracking of recent gigawatt-scale campuses shows 1 to 3.6 years from the start of construction to 1 GW of power.¹⁹ Whether utility study and construction delays count as government delay for tolling is unsettled: no guidance addresses it, so a sponsor should treat the question as open and not count on tolling to cover them.

Fund-level timing matters too. Investors have 180 days from a gain to invest, and the fund must meet its 90% asset test on two semiannual testing dates, so raising equity years before power is available creates pressure at both levels. See Data center power timelines and the Opportunity Zone clock.

Because the largest campuses are moving to places with land and transmission, and the rules give wholly rural zones better terms. A rural area is anywhere other than a city or town of more than 50,000 people and the urbanized area contiguous and adjacent to it.¹³ For property in a zone made up entirely of rural area, an existing building is substantially improved when additions to basis exceed 50% of its adjusted basis within 30 months, instead of 100%, a rule effective since July 4, 2025.¹³

A Qualified Rural Opportunity Fund (QROF), a fund holding at least 90% of its assets in wholly rural zones, gives investors a 30% basis step-up at year five for investments after December 31, 2026.¹⁸ Pillsbury argues these changes could make hyperscale campuses in rural zones more attractive.¹⁴ JLL reports that 77% of North American development is in frontier markets such as West Texas, Ohio, Louisiana, Indiana and the Carolinas.⁴ Siting issues are covered in Rural data centers and Opportunity Zones.

Newly designated zones take effect January 1, 2027 and run through December 31, 2036. A campus phased over a decade should confirm its tract's status on the new map before committing fund capital to later phases.

An illustrative 300 MW campus shows why phase size matters. The table assumes a landlord cost of $12 million per MW (inside the Cushman & Wakefield range⁷), tenant-owned servers, and three 100 MW phases, each with its own written working capital schedule.

Much of that cost is usually debt-financed, and only equity from deferred gains earns Opportunity Zone benefits. Projects often pair an Opportunity Zone equity tranche with conventional equity and construction debt; see The capital stack for an Opportunity Zone data center. For GPU-dense campuses, see AI data centers and Opportunity Zones.

Tenant concentration, power cost, local approval and federal policy are the main risks. A campus leased to one hyperscaler depends on one credit and one renewal decision, and utilities now shift more stranded-cost risk to large loads. AEP Ohio's tariff, approved July 9, 2025, requires new data centers above 25 MW to pay for at least 85% of subscribed demand for up to 12 years.¹⁷

Local opposition is rising. Data Center Watch counted at least 75 projects worth about $130 billion blocked or delayed in the first quarter of 2026 alone.¹⁶

Federal policy is in debate. On September 16, 2026, Sen. Josh Hawley introduced the No Tax Breaks for Data Centers Act, which would exclude data centers from Opportunity Zone benefits, and two House members introduced a bill to bar data centers from expanded incentives including Opportunity Zone benefits and 100% bonus depreciation. Sen. Ron Wyden released a framework with a similar aim.¹⁵ These are proposals; none had been enacted as of October 20, 2026. A sponsor should model the deal on current law, watch how any change would treat investments already made, and disclose the risk to investors.
