Shares of SoftBank Group jumped 3.6% to $18.60 Monday after Nvidia formalized a $1.5 billion equity investment in SB Energy, the SoftBank subsidiary building a massive data center in Ohio for OpenAI. The deal secures Nvidia up to 8 gigawatts of AI computing capacity at the Ohio campus. The move is company-specific — not part of any broader market rally — and extends a five-session streak that has lifted SFTBY over 11% from $16.76 on August 10.

  • Nvidia Is Paying to Guarantee Its Own Chip Sales — and SoftBank Benefits. The deal is the latest where Nvidia is financing the ecosystem consuming its chips, a strategy that has helped fuel demand but also drawn scrutiny over the circular flow of funds from the chipmaker to its biggest customers. For SoftBank shareholders, this means SB Energy receives a cash infusion and the imprimatur of the world's most valuable chipmaker. Under the terms, SB Energy will build, own, and operate the facility under a 20-year lease directly to OpenAI, with Nvidia serving as the exclusive AI computing infrastructure provider. A locked-in 20-year customer relationship substantially de-risks the subsidiary's revenue outlook.

  • The Ohio Project Is Enormous — and the Bill to Match. SB Energy and SoftBank plan to build at least 10 GW of new power generation and invest $4.2 billion in Ohio grid infrastructure to support AI data centers.

Capacity at the site is scheduled to come online in multiple phases starting in 2028. That timeline means heavy capital spending for years before meaningful cash flows arrive — a risk SoftBank shareholders must weigh against the long-term promise.

  • An IPO Worth Watching Could Surface Within Weeks. SB Energy's IPO could target a valuation exceeding $50 billion and may launch as soon as September.

Nvidia could commit another $1.5 billion through that public offering , potentially doubling its total stake. For SoftBank, which currently has a market capitalization near $282 billion, successfully listing a unit at that price would crystallize value that markets have struggled to assess. Analysts have noted SoftBank historically holds a large volume of unlisted assets, making it difficult for investors to accurately gauge portfolio value.

  • SoftBank Is Betting Globally, Not Just in Ohio. In May, SoftBank committed to developing 5 GW of AI data center capacity in France, representing investment of up to €75 billion. Combined with the Ohio campus and a Texas facility for OpenAI, SoftBank is assembling one of the largest private infrastructure footprints in the AI era — a strategy that could prove transformative or ruinously capital-intensive, depending on how long the AI spending boom lasts.
