AI infrastructure is heading for the public markets—and straight into a megawatt stress test. Quick context: OpenAI’s infrastructure buildout spans owned campuses, partner sites, rented servers, and financing structures that can shift risk onto suppliers. At PORTS-Pike in Ohio, NVIDIA provided credit support for an OpenAI-linked data-center buildout covering about 4.25 gigawatts of IT load. OpenAI has described the campus as an agreement for approximately 8 gigawatts-IT. This is The Data Center Daily. We’re checking an IPO filing and a deep-aquifer plan, then PG&E’s grid pilot. Let’s see which one has the receipts. This story isn't over: OpenAI Stargate build-versus-rent strategy. Follow us wherever you're listening, and the next chapter comes to you. This one's from Latitude Media:
Earlier this week, following a year of investments from the likes of Nvidia and OpenAI, the Softbank subsidiary filed for an initial public offering with the SEC, reportedly aiming to raise between $5 billion and $7 billion. The filing describes SB Energy as an “integrated data center and power infrastructure company.”
The OpenAI PORTS-Pike buildout now comes with its developer’s IPO filing. SB Energy is reportedly seeking $5 to $7 billion, with a $439 billion backlog in its S-1. It has 2.2 gigawatts of operating solar and storage, but no operating data-center or gas capacity. “Integrated data center and power infrastructure company” is a bold label on the cover page when the filing says it has no operating data-center capacity. Its footnotes ask investors to fund the before picture. PORTS-Pike has OpenAI as a tenant and plans 10 gigawatts of infrastructure, mostly new gas. Latitude puts the earliest operations in 2028, at the soonest. The scale is enormous on paper, but the build still has years to go. A $439 billion backlog can be very persuasive. It doesn’t energize a data hall, build a gas plant, or get federal-land construction through the finish line. From HPCwire:
The US$4 billion acquisition, by CPP Investments and Equinix, builds on CPP Investments’ global experience in data center investing and underscores the strategic importance of the Nordics as a leading hub for AI-ready digital infrastructure. atNorth will continue to operate independently under its existing brand, with the backing of its shareholders to accelerate development of its pipeline and expand capacity across the Nordics.
Equinix and CPP have closed the $4 billion atNorth acquisition. atNorth has eight operating Nordic facilities and projects across Sweden, Finland, Norway, and Denmark, while Partners Group is re-upping for 10%. After that SB Energy filing, it’s refreshing to see assets you can actually count. Four billion dollars bought an operating data-center platform, complete with existing operators and a development pipeline. That sounds a lot calmer than "$439 billion backlog," and I mean that as praise. atNorth keeps its brand and operational independence. Equinix brings customers, while CPP brings patient capital. HPCwire calls the Nordics power-cost advantaged, and the buyers are clearly betting AI demand follows the electricity economics. Shelly Molaschi, writing in MATR:
The facility will employ closed-loop cooling technology drawing water from the Deep Madison Group Aquifer, located 4,000 to 5,000 feet underground, well below the Eagle Aquifer relied upon by neighbors. The campus is projected to use 1,100 megawatts of power, with an application for 7,235 megawatts capacity pending before the Montana Public Service Commission. Water usage during peak construction could reach 150,000 gallons per day, but ongoing operations will use around 20,000 gallons daily.
Quantica wants 1.1 gigawatts at Broadview, but it has a 7.235-gigawatt capacity application sitting before Montana’s PSC. That docket is going to need a very large conference room. They’ve laid out an actual water plan: closed-loop cooling, roughly 20,000 gallons a day in operation, from the Deep Madison Aquifer 4,000 to 5,000 feet down. Peak construction is the bigger immediate draw—150,000 gallons a day. They’re deliberately staying below the Eagle Aquifer that neighbors use, which is a serious engineering choice. But farmers and ranchers are still being asked to trust long-term availability while the project is still exploring those options. Right. A 7.235-gigawatt application doesn’t mean 7.235 gigawatts delivered, and 1.1 gigawatts is still an enormous proposed load for Yellowstone County. The water disclosure is more concrete than most, but the power path is still expensive and unresolved. Brian Martucci, writing in Utility Dive:
Customers participating in Pacific Gas & Electric’s flexible interconnection pilot, which offers expedited hookups for agreeing to have the utility limit their capacity when the system is constrained, have been able to tap the distribution grid for their needed capacity in 90% of hours during its first two years, the program manager told Utility Dive this month.
PG&E has two years of receipts: Flex Connect customers got their needed capacity in 90% of hours, and active loads were affected less than 1% of the time. Turns out a utility can offer a conditional hookup without pretending the constraint vanished. And it can get larger distribution-connected loads energized in months, instead of waiting several years. The trade is explicit: PG&E can trim capacity during rare local-grid crunches. That’s a lot more usable than leaving a project parked in a firm-interconnection queue. Smaller data centers are already in that pipeline, alongside EV charging and storage. Put that next to the SB Energy filing: SB Energy has a 10-gigawatt ambition. PG&E is showing how curtailment works—and the actual performance. Flexible interconnection will not power every hyperscale campus. But 90% availability over two years is a number developers can model and regulators can test—much more useful than another round-number promise about AI demand.
