OpenAI leases 10-gigawatt AI data center campus from SoftBank’s SB Energy

What happened

OpenAI signed a 20-year lease for a massive AI data center campus in Ohio, covering 10 gigawatts of power capacity. The site is on the grounds of a former uranium processing plant. Construction is led by SB Energy, a SoftBank Group unit focused on building data centers and energy infrastructure.

Why it matters

The scale of this deal signals OpenAI’s move to massively expand its compute footprint. Ten gigawatts is an enormous power allocation, enough to support the kind of large-scale AI training and inference workloads that require vast energy and cooling resources. Leasing from SoftBank’s SB Energy also means OpenAI is locking down long-term infrastructure in a single location geared specifically for AI operations.

This gives OpenAI more control and capacity for handling ever-growing demand from advanced AI models. The deal could tighten market pressure on other cloud providers and infrastructure builders to match AI-specific data center capacity. It also raises the stakes for energy sourcing and efficiency since data centers at this scale will place significant demand on local power grids.

What to watch next

The actual timeline for this data center campus to come online will affect how quickly OpenAI can scale compute-intensive AI services. Watch for updates from SB Energy on construction milestones and energy sourcing details. Another point to watch is whether OpenAI builds additional AI campuses or partnerships with other infrastructure providers to distribute risk and capacity.

This move also invites attention to regional energy policies and grid readiness in Ohio, which will shape the sustainability and operational cost base of such massive AI compute facilities.
