Overview

SB Energy is the SoftBank-backed energy-and-data-center developer sitting at the middle of the vendor-financing round-trip pattern the corpus has been tracking since 2026-07-27-AI-Digest. Named developer / landlord of the PORTS-Pike Technology Campus in Pike County, Ohio — the OpenAI-leased 8 GW-when-optioned megacampus where NVIDIA has agreed to guarantee up to $105B of SB Energy’s lease-and-power-payment obligations as OpenAI absorbs capacity. SB Energy replaces the earlier Oracle role from the original Stargate blueprint on this site.

Timeline

  • 2026-08-18-AI-Digest — SB Energy is confirmed as the developer / landlord of the PORTS-Pike Technology Campus in Pike County, Ohio, with a 20-year exclusive tenancy signed with OpenAI — first phase 4.25 GW IT compute with an option for another 3.75 GW (8 GW total when exercised). SB Energy plus SoftBank are building 10 GW of new on-site generation with a $4.2B grid investment. NVIDIA is locked as the exclusive chip supplier for the site and has agreed to guarantee up to $105B of SB Energy’s lease-and-power-payment obligations — a contingent credit backstop that only draws down as OpenAI absorbs capacity (not cash on the table today). NVIDIA also puts $1.5B in direct equity into SB Energy. First units 2028. Load-bearing framing to carry: the $105B is a guarantee, not an investment — headline framings that read it as “NVIDIA to invest $105B” (including Bloomberg’s own URL slug) misstate the shape of the commitment; the $105B is off-balance-sheet backing of SB Energy’s lease and power payments, drawn only if OpenAI holds the compute. Structural read: SB Energy is now the load-bearing counterparty on the largest vendor-financing round-trip the corpus has recorded — chip supplier underwrites developer’s lease obligations to foundation-model tenant, developer contracts back to chip supplier for chip supply, and the whole envelope only clears if OpenAI’s demand curve holds through 2028.

Key Developments

  1. PORTS-Pike Technology Campus — 20-Year OpenAI Tenancy at 4.25 GW Initial + 3.75 GW Option (August 17–18, 2026): SB Energy is the developer / landlord of the Pike County, Ohio megacampus where OpenAI signs a 20-year exclusive lease. First-phase IT compute is 4.25 GW with an option for another 3.75 GW (8 GW total when exercised); SB Energy + SoftBank build 10 GW of new on-site generation with $4.2B in grid investment; first units 2028. The 8 GW headline figure assumes the option gets exercised — a 2028-onward decision, not a signed commitment today.

  2. $105B NVIDIA Guarantee — Contingent Credit Backstop, Not Investment (August 17–18, 2026): NVIDIA agrees to guarantee up to $105B of SB Energy’s lease-and-power-payment obligations at PORTS-Pike as OpenAI absorbs capacity — the $105B is a contingent credit backstop, not equity or a loan. Cash exposure today is $1.5B NVIDIA equity in SB Energy. The mechanism is the same one NVIDIA pioneered with CoreWeave ($6.3B) and Lambda ($1B) — the PORTS-Pike envelope is roughly 15× the earlier backstops and lands as a new capital-formation channel where a chip supplier’s balance sheet underwrites a foundation-model lab’s compute lease. SB Energy is the counterparty NVIDIA’s guarantee sits on.

  3. 10 GW On-Site Generation Buildout — Power as the Second Binding Constraint (August 17–18, 2026): SB Energy + SoftBank commit to build 10 GW of new on-site generation with $4.2B in grid investment to serve PORTS-Pike. Reads directly against the corpus’s running “power has joined HBM and CoWoS packaging as a binding constraint on frontier scale” thesis — SB Energy’s ability to place the on-site generation-plus-grid bond issuance at scale is the load-bearing next-quarter watch item; the $220B YTD 2026 hyperscaler bond figure has already priced in a lot of this class of paper.
