The Stargate Initiative (formally The Stargate Project, incorporated in Delaware as Stargate LLC) is an American joint venture announced on January 21, 2025 to build AI infrastructure for OpenAI inside the United States. Its founding partners are OpenAI, SoftBank, Oracle, and MGX, with SoftBank holding financial responsibility and OpenAI holding operational responsibility. The venture committed $100 billion immediately and stated an ambition to deploy up to $500 billion over four years across new data center campuses in the U.S., with international counterparts subsequently announced for the United Arab Emirates, Norway, the United Kingdom, and Argentina. The flagship campus, Stargate I, sits on the Lancium Clean Campus in Abilene, Texas, where Crusoe Energy is developing a 1.2 GW build-out for OpenAI on Oracle Cloud Infrastructure.

Reporting on a project codenamed "Stargate" predated the formal joint venture by nearly a year. In late March 2024, The Information reported that Microsoft and OpenAI were drawing up plans for a $100 billion data center build called Stargate, intended to host an OpenAI training supercomputer that could draw as much as 5 gigawatts of power and come online around 2028. At that point Microsoft was still OpenAI's exclusive cloud provider, and the project was framed as the culmination of a multi-year capital expenditure plan between the two firms.
OpenAI's compute appetite kept outrunning the supply that any single hyperscaler could comfortably provide. Through 2024, OpenAI's executives publicly argued that frontier model training would require purpose-built campuses on a scale that did not yet exist. By late 2024 the company was openly discussing a multi-partner approach, and reporting from Reuters and The Wall Street Journal placed Oracle, SoftBank, and Abu Dhabi sovereign investor MGX in the room with Sam Altman. The structure that emerged in January 2025 turned the older Microsoft-OpenAI "Stargate" supercomputer concept into a wider consortium with new lead financiers.
The Stargate Project was unveiled at the White House on January 21, 2025, the day after Donald Trump was inaugurated for his second term. Trump appeared in the Roosevelt Room alongside Sam Altman (OpenAI), Larry Ellison (Oracle), and Masayoshi Son (SoftBank). He called it "the largest AI infrastructure project in history" and said he would use emergency declarations to speed up energy approvals tied to the build-out. The announcement put the headline figure at up to $500 billion over four years, with $100 billion to begin deploying immediately.
Altman, in his remarks, told the President, "We wouldn't be able to do this without you, Mr. President," and added, "I think this will be the most important project of this era." Ellison used his time at the lectern to argue that AI on the scale of Stargate could enable personalized cancer vaccines: "You can make that vaccine, that mRNA vaccine, you can make that robotically again using AI in about 48 hours." Son framed Stargate as the catalyst for what he called "the dawn of artificial superintelligence." Trump and the participating companies claimed Stargate would create over 100,000 American jobs.
In parallel with the White House event, OpenAI published a blog post titled Announcing The Stargate Project, which named NVIDIA, Microsoft, Arm, and Oracle as initial technology partners and confirmed the four founders. Construction was already underway in Abilene, Texas, well before the press conference; the press event served as a public unveiling rather than a groundbreaking.
| Partner | Role | Notes |
|---|---|---|
| OpenAI | Operational lead | Tenant and customer for Stargate compute capacity. Reported to hold roughly 40% equity, with $19 billion committed at launch. |
| SoftBank | Financial lead | Chairman: Masayoshi Son. Reported to hold roughly 40% equity, with $19 billion committed at launch. First $10 billion tranche borrowed from Mizuho and other lenders, announced April 1, 2025. |
| Oracle | Cloud and infrastructure | Operates Stargate I on Oracle Cloud Infrastructure. Reported to contribute $7 billion at launch. Signed a separate 4.5 GW Stargate expansion agreement with OpenAI in July 2025. |
| MGX | Sovereign-wealth investor | Abu Dhabi-based AI investment vehicle. Reported to contribute $7 billion at launch and to anchor the UAE-based Stargate cluster announced in May 2025. |
Equity numbers above were first reported by The Information on January 23, 2025, citing people familiar with the structure. Stargate's official statements have not published equity stakes; the partners' filings and press releases refer to the venture in aggregate terms. Remaining capital, beyond the initial four shareholders, is expected to come from limited partners and project-level debt.
OpenAI's launch announcement identified four "key initial technology partners" beyond the founding investors: NVIDIA, Microsoft, Arm, and Oracle. The wider partner list expanded through the year as the venture signed bilateral compute deals.
| Partner | Role |
|---|---|
| NVIDIA | Primary GPU supplier. Oracle began delivering NVIDIA GB200 racks to Abilene in June 2025, with later sites slated for the GB300 generation. |
| Microsoft | Holds right of first refusal on future OpenAI cloud capacity (modified from exclusivity, January 21, 2025). Continues to host OpenAI workloads on Azure under a separate large commitment. |
| Arm | CPU architecture for Grace and Grace Blackwell systems used in Stargate buildouts; SoftBank's controlling stake in Arm overlaps with its position in Stargate. |
| Oracle | Cloud operator for Stargate I and signed a separate $300 billion, 4.5 GW Stargate expansion deal with OpenAI in July 2025. |
| AMD | Strategic partner from October 6, 2025: agreed to supply 6 GW of Instinct MI450 GPUs starting H2 2026. As part of the deal, AMD granted OpenAI a warrant for up to 160 million shares (about 10%). |
| Cisco | Networking and zero-trust security; named in the May 2025 Stargate UAE consortium. |
| Broadcom | Custom silicon partner; OpenAI announced a 10 GW commitment for Broadcom-designed XPU systems in late 2025. |
| CoreWeave | Capacity partner referenced in Stargate progress updates alongside Abilene and the new U.S. sites. |
The flagship Stargate campus is on the Lancium Clean Campus, an 1,100-acre site north of Abilene, Texas. Construction had begun under the codename "Project Ludicrous" in June 2024, well before the January 2025 White House announcement. Crusoe Energy is the lead developer; Lancium provides the underlying campus and grid interconnection; Oracle is the cloud operator and the long-term tenant on behalf of OpenAI.
Phase 1 (the first two of eight planned buildings) was energized within roughly a year of breaking ground. Oracle started delivering NVIDIA GB200 racks in June 2025, and on September 30, 2025 Crusoe and OpenAI announced the campus was live and running early training and inference workloads on Oracle Cloud Infrastructure. In March 2025, Crusoe began phase 2, which adds six more buildings; at full build-out the campus is sized for roughly 4 million square feet and 1.2 GW of total IT power. Local reporting puts the workforce on site at around 5,000 construction workers in late 2025, with the campus expected to be substantially complete in early 2027.
In an update titled OpenAI, Oracle and SoftBank expand Stargate with five new AI data center sites, the partners disclosed five additional U.S. campuses. Three are Oracle-led; two are SoftBank-led. Stargate said the five sites, plus Abilene and a separately referenced CoreWeave-supported tranche, brought announced capacity to about 7 GW and committed investment to over $400 billion over three years.
| Site | Lead partner | Notes |
|---|---|---|
| Shackelford County, Texas | Oracle | Adjacent to Abilene infrastructure footprint |
| Doña Ana County, New Mexico | Oracle | Reported in November 2025 to be financed by an $18 billion bank-led project loan |
| Wisconsin (Port Washington, near Milwaukee) | Oracle with Vantage Data Centers | Confirmed October 22, 2025 as the previously undisclosed Midwest site; "Lighthouse" campus, near 1 GW, $15 billion+ |
| Lordstown, Ohio | SoftBank | Ground broken; targeted operational in 2026 |
| Milam County, Texas | SoftBank with SB Energy | Fast-build design; SB Energy provides powered shell |
On October 30, 2025, OpenAI, Oracle, and Related Digital announced an additional Stargate campus of more than 1 GW in Saline Township, Michigan, with construction expected to start in early 2026.
| Country | Local partner | Announced | Capacity / scope |
|---|---|---|---|
| United Arab Emirates | G42 (with Oracle, NVIDIA, Cisco, SoftBank) | May 22, 2025 | 1 GW Stargate UAE cluster inside a 5 GW UAE-U.S. AI campus in Abu Dhabi; first 200 MW phase due 2026 |
| United Kingdom | Nscale and OpenAI | Discussed April 2025; formal announcement later in 2025 | Up to 8,000 GPUs initially across Nscale data centers |
| Norway | Nscale and Aker | July/August 2025 | Stargate Norway in Kvandal, near Narvik; 230 MW initial, target 100,000 NVIDIA GPUs by end of 2026, hydropower |
| Argentina | Sur Energy | October 10, 2025 | Stargate Argentina in Patagonia; up to 500 MW, estimated up to $25 billion |
Not every international site is owned by Stargate LLC. Several, including Stargate Norway, are structured as separate joint ventures (Norway is a 50/50 between Nscale and Aker) where OpenAI is an anchor tenant rather than an equity holder. The Norway project's status shifted in early 2026 when CNBC reported that OpenAI was pulling back from directly renting capacity in Kvandal, with Microsoft expected to absorb the spare compute.
Stargate LLC's stated capital plan combines equity from the four founders, additional equity from limited partners, and significant project-level debt. The headline numbers ($100 billion immediately, up to $500 billion over four years) cover the full venture rather than any single site.
Key financing milestones in the first year:
The gap between announced totals and actually deployed dollars was a recurring story through 2025. On August 7, 2025, Bloomberg reported that the project had raised no new outside funding to meet the $500 billion target, attributing the lag to market uncertainty around tariffs and AI hardware valuations. By the end of the year, financing was visibly catching up at the project level even though the full $500 billion remained a forward-looking aspiration rather than a closed sum.
On the same day as the Stargate announcement, Microsoft and OpenAI revised the cloud-computing terms of their partnership. Microsoft was no longer OpenAI's exclusive provider; instead it received a right of first refusal on future OpenAI cloud capacity. If Microsoft declined to provide a particular tranche of compute, OpenAI could go elsewhere, including to Stargate's Oracle-operated infrastructure. Microsoft retained its existing intellectual property rights and continued to be the exclusive provider behind OpenAI's API workloads.
Microsoft CEO Satya Nadella confirmed Microsoft's $80 billion fiscal-year capital expenditure commitment in a public response to early skepticism: "All I know is I'm good for my $80 billion." The relationship was rewritten more broadly later in 2025 and again in 2026: in October 2025, Microsoft and OpenAI announced a new chapter that gave Microsoft a roughly 27% economic stake in OpenAI's restructured for-profit alongside a $250 billion Azure commitment from OpenAI, while formally ending Microsoft's right of first refusal on cloud capacity.
The morning after the announcement, Elon Musk attacked the project on X, posting that the partners "don't actually have the money" and writing, "SoftBank has well under $10B secured. I have that on good authority." Musk's xAI is a direct OpenAI competitor and he had been suing OpenAI and Altman since 2024, which colored the reception of his comments. Sam Altman responded directly: "wrong, as you surely know," and added that he wished Musk "would do what's right for the country." Sources close to the venture told Fox Business that the consortium was "prepared to deploy the $100 billion immediately," pointing to founder equity, co-investor equity, and third-party debt. Musk's claim about SoftBank's available cash was never independently confirmed, but the slow pace at which Stargate's capital actually arrived through the first half of 2025 gave it more traction than its source might have warranted on its own.
Son framed Stargate as a generational bet. At the announcement he tied it to his vision of artificial superintelligence and stood by the chairman role personally. SoftBank's actions through 2025 backed up the rhetoric in real money: a $10 billion borrowing in April, a separate $30 billion commitment to OpenAI itself, and, in November 2025, a near-complete sale of SoftBank's NVIDIA position (valued at about $5.8 billion) to free capital for the OpenAI and Stargate commitments. The choice to sell the NVIDIA stake while simultaneously buying Stargate compute that runs on NVIDIA chips drew outside commentary about the depth of Son's conviction in OpenAI specifically.
Reporting tone shifted over the year. The first wave (CNBC, CNN Business, Reuters, Time) treated the announcement as a headline event, with most outlets noting the gap between Trump's branding of Stargate as a federal project and its underlying private structure. Bloomberg's February 4 piece, headlined "Stargate: Is Trump's New $500 Billion AI Project Reality or Bluster?", set the skeptical baseline. By late summer the same outlet was reporting on funding delays. By the September 23 expansion, Fortune, TechCrunch, and Data Center Dynamics coverage had moved toward treating Stargate as a real, if uneven, build-out. Substantive industry skepticism focused less on whether anything would be built (something clearly was, in Abilene) than on whether the full $500 billion figure would ever close on the original four-year timeline.
The most concrete milestone in Stargate's first year was Stargate I going live. Crusoe and OpenAI confirmed on September 30, 2025 that the first phase of the Abilene campus was operational on Oracle Cloud Infrastructure, running early training and inference workloads. By the end of October 2025, Crusoe had topped out the final building of the eight-building Abilene campus on the structural side, even as interior fit-out continued.
In parallel, ground was broken at the Lordstown, Ohio site (SoftBank-led) and at Vantage's Wisconsin campus, with Vantage announcing roughly $15 billion in committed investment in Port Washington. Related Digital began permitting the Saline Township, Michigan site for an early-2026 construction start. International progress in 2025 centered on G42's Stargate UAE construction in Abu Dhabi, where the first 200 MW phase remained on track for a 2026 opening.
Not every site advanced cleanly. Distilled.earth's November 2025 piece on "the world's largest planned data center" cited grid interconnection delays in Texas, and the May 2025 Bloomberg report flagged that tariff uncertainty had snagged some procurement decisions. By early 2026, CNBC reported that OpenAI was stepping back from directly renting Kvandal capacity in Norway, with Microsoft taking the displaced workloads. Fortune reported in March 2026 that Microsoft had picked up a Texas data center project that OpenAI had passed on, which was widely read as a sign that the two former exclusive partners had now drifted into something closer to a competitive relationship around physical capacity.
