Stargate is a US data-centre venture launched in January 2025 by OpenAI, Oracle, SoftBank and Abu Dhabi's MGX, aiming to invest up to $500 billion over four years to build the computing capacity for advanced artificial intelligence — the largest AI infrastructure programme ever announced.
In January 2025, a group of the most powerful companies in technology and finance announced a single number that reframed how the market thinks about artificial intelligence: up to $500 billion, to be spent over four years, building the physical computing capacity for AI in the United States. The venture is called Stargate, and it is the largest privately led infrastructure programme of the AI era.
What is Stargate?
Stargate is a joint venture, announced on 21 January 2025, formed to design, build and operate a network of large-scale data centres across the United States dedicated to training and running advanced artificial intelligence systems. Its purpose is straightforward to state and staggering to execute: assemble the land, power, buildings, chips and networking needed to support the next generations of AI models at a scale no single company had previously committed to.
The founding partners are OpenAI, Oracle, SoftBank and MGX, the Abu Dhabi state-backed artificial-intelligence investment company. SoftBank and OpenAI are the lead partners. SoftBank carries financial responsibility for the venture, while OpenAI carries operational responsibility — that is, OpenAI runs the compute the project produces. Oracle and MGX round out the founding equity backers, and Arm, Microsoft and NVIDIA are named technology partners supplying chips, cloud and design capability.
The presence of MGX is significant for the institutional audience. It places Gulf sovereign capital — through an Abu Dhabi vehicle created expressly to invest in AI and its infrastructure — at the centre of the defining technology build-out of the decade, alongside the world's leading AI lab and two of its largest technology and investment companies.
How big is Stargate, really?
The headline is up to $500 billion over four years. That figure should be read carefully. It is an intended total investment, not a single committed sum, and a substantial portion is expected to be financed through debt and infrastructure project finance rather than equity cheques written upfront. The right mental model is a staged, ambitious build-out programme backed by escalating commitments, not a guaranteed half-trillion-dollar wire transfer on day one.
That said, the programme has scaled with unusual speed. In September 2025, the partners announced five new data-centre sites and said the combined capacity — together with the flagship Texas campus and ongoing projects — brought Stargate to nearly 7 gigawatts of planned capacity and more than $400 billion of investment over a roughly three-year horizon. They described the full $500 billion, approximately 10-gigawatt commitment as on track to be reached by the end of 2025, ahead of the schedule set out at launch. Separately, in July 2025 OpenAI and Oracle agreed to develop up to 4.5 gigawatts of additional Stargate capacity, a partnership the companies said exceeded $300 billion over five years.
To put 10 gigawatts in perspective: that is comparable to the peak electricity demand of a mid-sized country, dedicated to a single computing purpose. The energy dimension is not a footnote to Stargate; it is one of the binding constraints around which the entire project is organised.
Where is Stargate being built?
The flagship campus is in Abilene, Texas, and it is already operating. It runs on Oracle Cloud Infrastructure, with Oracle having begun delivering NVIDIA's GB200 systems in mid-2025 and early AI training and inference workloads already drawing on the capacity. The first site is therefore not a rendering or a groundbreaking ceremony — it is live infrastructure.
The September 2025 expansion added sites in Shackelford County, Texas; Doña Ana County, New Mexico; an undisclosed location in the US Midwest, all developed with Oracle; and two further sites at Lordstown, Ohio, and Milam County, Texas, to be built by SoftBank affiliates. The geographic spread reflects the practical realities of the build: developers go where land, grid interconnection and power are available, which increasingly means siting capacity away from saturated coastal data-centre clusters.
Why does Stargate matter to long-term asset owners?
A universal asset owner — a large pension fund, sovereign wealth fund, endowment or insurer that effectively holds a slice of the entire economy — cannot treat Stargate as someone else's story. It touches their portfolios through several channels at once.
The first is concentration in public equities. The technology companies driving and supplying the AI build-out — chipmakers, cloud providers and the largest platform companies — sit at the top of global equity indices. An investor who passively holds the world's stock market is, by construction, heavily exposed to whether this enormous bet on AI compute pays off. Stargate is among the clearest expressions of that bet.
The second is infrastructure and real assets. Data centres, the power generation and transmission that feed them, and the long-dated contracts that underpin them are exactly the kind of assets that pension and sovereign funds increasingly want to own directly. Stargate is creating a vast new pipeline of such assets — and the financing structures behind it, heavy on debt and project finance, are precisely where institutional capital is being invited in.
The third is the energy transition and grid. Stargate's power appetite collides directly with the constraints facing electricity systems, a subject we examine in our companion explainer on data-centre power demand and the grid. For an asset owner with holdings across utilities, renewables, gas and grid infrastructure, the AI build-out is reshaping the demand outlook for energy in ways that affect valuations across the whole stack.
The fourth is geopolitics and sovereign capital. With MGX as a founding backer, Stargate illustrates how Gulf states are converting resource and reserve wealth into ownership of frontier technology infrastructure — a theme that recurs across the strategies of the region's largest funds and that long-horizon allocators are watching closely.
What are the risks around Stargate?
The scale that makes Stargate important also makes it risky, and a sober investor should hold the ambition and the uncertainty together. The economics depend on sustained, monetisable demand for AI compute at prices that justify hundreds of billions of dollars of fixed investment. If AI revenue grows more slowly than the build implies, or if more efficient models reduce the compute required per unit of output, some of this capacity could be built ahead of the demand to fill it.
Execution risk is equally real. Securing power at this scale, on this timeline, is genuinely hard; grid interconnection queues, equipment lead times and local opposition can all slow delivery. And the financing model — leaning heavily on debt against assets whose long-run utilisation is not yet proven — concentrates the consequences of a demand shortfall.
For asset owners, the appropriate posture is neither dismissal nor uncritical enthusiasm. Stargate is a real, fast-moving programme that is already changing the demand picture for compute, power and infrastructure. It is also a leveraged bet on a technology whose ultimate economics remain unsettled. Understanding both halves of that statement — and knowing where one's own portfolio sits on each side of it — is the work that long-term ownership requires.
