The developer of OpenAI's Ohio campus has the leases. The IPO and the debt to build it are proving harder.

One of the nine conditions this map tracks asks a blunt question about the AI build-out: who actually pays for it? This week produced an unusually clean test. SB Energy, the SoftBank subsidiary developing the campus in Pike County, Ohio that OpenAI has leased, went to market for the money to build it, and the market asked for better terms.

Start with what is on the record. SB Energy filed to list on Nasdaq on 1 September and amended the filing on 21 September. The filing says it has signed 20-year leases with an OpenAI affiliate for 17 buildings at the Ohio site, about 8 gigawatts of computing capacity in all. It says no data center capacity is in operation yet, that the first phase is targeting 2028 subject to financing and approvals, and that the capital spending tied to its signed data center backlog comes to about 174 billion dollars. The price range in the filing is still blank.

Now the reporting. On 22 September the Financial Times reported that SB Energy was slowing its IPO, and that early talks with investors on a potential 4.9 billion dollar debt sale tied to the listing suggested buyers wanted a yield of about 10 percent, a level associated with speculative-grade credit. A person close to the company told the paper it would focus on the IPO first and look at more debt after listing. The New York Times reported that bankers had struggled to find enough buyers at a valuation of 50 billion dollars or more, and that a listing was not expected before mid-to-late October.

On 25 September two more outlets filled in the picture. Reuters reported that SB Energy had postponed plans to formally market the IPO that week while it answered further questions from the Securities and Exchange Commission, and that investors had raised concerns about the valuation and about its reliance on OpenAI as a customer. IFR reported that interest during premarketing came in below the valuation sought, and that the banks were holding off until the gap closed. The company declined to comment to Reuters and has not named a new date.

The 10 percent figure needs context, and the filing supplies a yardstick. In May, SB Energy sold 999 million dollars of secured notes backing a campus in Texas at 8.875 percent. A reported 10 percent is more than a point above that, for a far larger and less proven project. It is also a figure from early talks, not a priced deal.

Why does this land on SoftBank rather than on SB Energy? Because SB Energy is not on this map, and SoftBank is. SoftBank is the controlling shareholder, and according to Reuters it had been hoping for cash from both the SB Energy and the OpenAI listings, both of which have now slipped. IFR also reported that SoftBank has been working with banks on a margin loan secured against part of its SB Energy stake. IFR read that as a sign of conviction. It is also one more loan against one more holding.

Now the case against reading too much into it. A person familiar with the plans told Investing.com on 22 September that the IPO was proceeding as intended and that no September date had ever been confirmed. IFR's own sources said the testing-the-waters calls met a broadly positive reception. Nvidia has committed 3 billion dollars of equity and, according to the filing, guarantees of up to 105 billion dollars on the first 4.25 gigawatts of OpenAI's lease. A developer with those backers is not short of support. And a listing that moves by a few weeks is not a failed listing.

What it does show is narrower and more useful. The demand side of this project is signed. The financing side is being priced in public, in a month when Holtec postponed its listing and a power dispute surfaced at a Stargate site in New Mexico. When a developer with OpenAI as tenant and Nvidia as guarantor is reportedly asked for close to 10 percent, the cost of money has become part of the question of whether announced capacity turns into working capacity.

What would change the picture is observable. The IPO pricing, or being postponed again. The debt sale being launched and priced, and at what yield, or being dropped. Any change to the 2028 Ohio timetable or to OpenAI's leases. SoftBank confirming the margin loan.

On the map: SoftBank turns yellow. Data centers and physical infrastructure was already red from the Virginia and Texas actions and stays red. OpenAI does not change color, because OpenAI did nothing here, and Nvidia's commitments are unchanged. Nothing turns red, and none of this says anything about whether AI demand is holding up. It is about whether the money to build arrives on the terms the plan assumed.
