A $5.5 billion warrant exposes the circular economics of AI infrastructure

The Wall Street Journal's review of draft IPO documents offers a rare view into the financial loop supporting the AI data-center boom. OpenAI was issued warrants in SoftBank-backed SB Energy valued at an estimated $5.5 billion at the end of June, up from $3.6 billion when awarded in January. OpenAI also invested $500 million in SB Energy and signed 17 leases covering about eight gigawatts at a planned Ohio campus. SB Energy, in turn, committed to purchase at least $50 million of OpenAI services through 2028. Nvidia has an equity position and reportedly committed $3 billion through transactions tied to the IPO, while its residual-value guarantee is important to financing the Ohio project. The circularity does not prove the buildout is unsound, but it complicates the demand signal. SB Energy's data-center segment reportedly has no operating revenue, has 800 megawatts under construction, and claims more than $400 billion in contracted backlog, much of it tied to infrastructure not yet built. Investors and communities should separate independent demand from related-party support by examining customer concentration, warrant terms, cross-purchases, power availability, construction milestones, guarantees, and the downside if one member of the ecosystem cannot perform.
