SoftBank's $70 Billion Ohio AI Megaproject: The Biggest Infrastructure Bet in American History

Forget ribbon-cutting ceremonies for a new factory. What just landed in Piketon, Southern Ohio, is something far more audacious — a publicly-backed AI industrial district carved out of a former uranium enrichment complex.

Today the U.S. Departments of Energy and Commerce locked in a formal public-private partnership with SoftBank's SB Energy and AEP Ohio. The price tag? Roughly $70 billion, spread across a 10-gigawatt AI data center ($30–$40 billion in chips and equipment alone), a 9.2 GW natural gas power plant (~$33 billion), and $4.2 billion in new transmission lines. This isn't a project. It's a full-blown American industrial resurrection.

The Machine Behind the Machine

SB Energy — SoftBank's fully integrated U.S. digital infrastructure arm — is driving this. Back in January 2026, OpenAI and SoftBank each poured $500 million into SB Energy, effectively crowning it OpenAI's go-to developer for multi-gigawatt AI campuses. That relationship gives Piketon serious structural credibility. It slots directly into the $500 billion Stargate initiative, jointly backed by OpenAI, SoftBank, and Oracle, chasing 10 GW of U.S. AI computing capacity. Five Stargate sites were already confirmed by September 2025. Piketon is the crown jewel.

Ohio's role runs even deeper. SoftBank is converting GM's old Lordstown plant into a modular data center manufacturing facility — up to $3 billion, reportedly operational in early 2026. Down in Milam County, Texas, a 1.2 GW solar-and-battery campus for OpenAI is already taking shape. Ohio isn't one bet. It's the spine of a vertically integrated AI infrastructure empire.

Power Is the New Chip Shortage

Here's what the semiconductor headlines miss. The DOE estimates data centers consumed 4.4% of U.S. electricity in 2023 — potentially hitting 12% by 2028. PJM's load forecasts confirm the obvious: AI infrastructure is now the dominant demand driver across the Midwest and Mid-Atlantic grids. The real bottleneck today isn't chips. It's dispatchable, dedicated power at massive scale.

The proposed gas plant would be the largest gas-fired facility in American history, capable of powering roughly 7.5 million homes. SB Energy also confirmed an extra 800 MW on top of that. Meanwhile, Trump's "Ratepayer Protection Pledge" — requiring tech firms to foot their own electricity bills rather than passing them to households — has political logic behind it. AEP Ohio customers already absorbed average monthly bill hikes of $27 last summer, purely from data center load. That number isn't abstract. Real people feel it.

A Bullish Signal. Not a Banked Win.

Let's be honest about what Piketon is and what it isn't. Strategically, it's enormous. Economically, it's still half-built on paper. No fuel supply arrangements have been disclosed. No interconnection sequencing, no construction phasing, no named turbine manufacturer, no formal power offtake structure. These aren't footnotes — they're the variables that decide whether this becomes a cash-flowing asset or a decade-long development saga.

AEP benefits here, but carefully. Ohio's PUCO has already approved a tariff requiring large loads to absorb their own infrastructure costs, and AEP reports 17.861 GW of contracted data-center load through 2035 against a historical Ohio peak of 8–10.5 GW. That's constructive for its regulated transmission story. However, the upside hinges on allowed returns, capital allocation, and timing — not press releases.

Gas-turbine makers like GE Vernova get another demand signal but not yet a booked order. Turbine lead times have ballooned across GE Vernova, Siemens, and Mitsubishi as AI-driven power demand surged globally — and that backlog is itself a brake on Piketon's timeline. Oracle gets a narrative boost, nothing more tangible yet.

The sharpest long-duration thesis? Transmission infrastructure. The cleanest structural winner from every multi-gigawatt AI campus is the wire — not the generator.

The Risks Most Investors Will Sleep Through

Senate Democrats launched a formal probe into gas-powered AI data centers in March 2026, zeroing in on air pollution and environmental justice. Ohio's Senate Bill 294 — which would reclassify natural gas as "clean energy" — has become a political flashpoint. And the Piketon site itself sits within the broader Portsmouth uranium-enrichment complex, still under active DOE remediation. Permitting fights and environmental litigation don't resolve in quarters. They resolve in years.

Watch for the real signals: a named turbine package, PJM interconnection milestones, gas supply commitments, phased completion dates. Until those materialize, Piketon is a high-significance strategic moment — and a medium-significance equity event.
