The Scale of Ambition: 10 Gigawatts of Computing Power

The partnership centers around an unprecedented infrastructure buildout that will see the deployment of at least 10 gigawatts of Nvidia systems for OpenAI’s next-generation AI infrastructure. To put this scale into perspective, this computing power is equivalent to 4 to 5 million AI accelerators, matching the total number of AI accelerators Nvidia will ship this year and double that of last year, according to Nvidia CEO Jensen Huang.

A data center campus with peak demand of one gigawatt is roughly equivalent to the average annual consumption of about 700,000 homes, or a city of around 1.8 million people. This means the full 10-gigawatt deployment could consume as much electricity as a metropolitan area housing 18 million people – nearly the size of New York City’s metro area.

The sheer magnitude of this power requirement underscores the energy-intensive nature of modern AI systems. Nvidia CEO Jensen Huang told CNBC that the 10 gigawatt project with OpenAI is equivalent to between 4 million and 5 million graphics processing units, representing a massive concentration of computing resources dedicated to advancing artificial intelligence capabilities.

Financial Structure and Timeline

The investment will be deployed progressively, with Nvidia’s first $10 billion investment beginning when the two companies reach a definitive agreement for OpenAI to purchase Nvidia chips. The deal involves two separate but intertwined transactions, with the startup paying Nvidia in cash for chips, and Nvidia investing in OpenAI for non-controlling shares.

The first gigawatt of Nvidia systems will be deployed in the second half of 2026 on Nvidia’s Vera Rubin platform, representing the next generation of AI computing infrastructure. This timeline reflects the complex nature of building data centers at this scale, which requires substantial power infrastructure, cooling systems, and specialized facilities.

The investment structure addresses a critical need for OpenAI, which was most recently valued at $500 billion. As the company continues to grow its user base – now boasting over 700 million weekly active users and strong adoption across global enterprises, small businesses and developers – the demand for computing infrastructure has become a primary constraint on further expansion.

Market Reaction and Strategic Implications

Financial markets responded enthusiastically to the announcement. Nvidia stock rose almost 4% during Monday trading, instantly adding close to $170 billion in value to the company’s market cap, which now sits near $4.5 trillion. The broader market also rallied, with the S&P 500 climbing more than 0.3% to touch a fresh all-time high.

Oracle, which serves as a partner with OpenAI, SoftBank, and Microsoft on the $500 billion Stargate AI data center project, gained about 6%, highlighting how the partnership creates ripple effects throughout the AI infrastructure ecosystem.

The deal represents a significant strategic shift for both companies. For Nvidia, it provides a direct financial stake in the world’s most prominent AI company while ensuring a massive, long-term customer for its most advanced chips. For OpenAI, it secures access to cutting-edge computing resources essential for maintaining its competitive edge in an increasingly crowded AI market.

The Broader AI Infrastructure Boom

This partnership occurs against the backdrop of an unprecedented expansion in AI infrastructure investment. Companies across the compute power value chain will need to invest $5.2 trillion into data centers by 2030 to meet worldwide demand for AI alone, according to McKinsey analysis. The scale of this investment reflects the fundamental transformation occurring in how we process and interact with information.

The energy requirements are staggering. Goldman Sachs Research estimates that there will be around 122 GW of data center capacity online by the end of 2030, with AI workloads driving much of this growth. The International Energy Agency projects that electricity demand from data centres worldwide is set to more than double by 2030 to around 945 terawatt-hours, slightly more than the entire electricity consumption of Japan today.

These projections help contextualize the Nvidia-OpenAI deal not as an isolated transaction, but as part of a broader transformation of global infrastructure. BloombergNEF forecasts US data-center power demand will more than double by 2035, rising from almost 35 gigawatts in 2024 to 78 gigawatts, with OpenAI’s planned infrastructure representing a significant portion of this growth.

Competitive Dynamics and Market Positioning

The partnership strengthens both companies’ positions in an increasingly competitive landscape. OpenAI and Nvidia will work together to co-optimize their roadmaps for OpenAI’s model and infrastructure software and Nvidia’s hardware and software, creating potential competitive advantages through deep integration.

However, the deal has raised concerns about market concentration. “Nvidia invests $100 billion in OpenAI, which then OpenAI turns back and gives it back to Nvidia,” noted Bryn Talkington, managing partner at Requisite Capital Management, highlighting the circular nature of the investment structure.

Four companies – Amazon Web Services (AWS), Google, Meta and Microsoft – currently control 42% of US data-center capacity. AWS alone has plans to quadruple its current 3-gigawatt capacity to nearly 12 gigawatts, indicating substantial influence over regional infrastructure by a small number of tech giants.

Regulatory and Antitrust Considerations

The scale of the investment and the market positions of both companies have attracted attention from competition watchdogs. The Justice Department and the Federal Trade Commission reached a deal in June 2024 that cleared the way for potential antitrust investigations into the dominant roles that Microsoft, OpenAI and Nvidia play in the artificial intelligence industry.

However, the Trump administration has taken a much lighter touch on competition issues compared with former President Joe Biden’s antitrust enforcers, potentially reducing regulatory obstacles to large-scale AI infrastructure investments.

Legal experts suggest the deal could face scrutiny. “The deal could change the economic incentives of Nvidia and OpenAI as it could potentially lock in Nvidia’s chip monopoly with OpenAI’s software lead,” said Andre Barlow, an antitrust lawyer with Doyle, Barlow & Mazard, noting that it “could potentially make it more difficult for Nvidia competitors like AMD in chips or OpenAI’s competitors in models to scale.”

Technical Innovation and Platform Evolution

The partnership will debut on Nvidia’s Vera Rubin platform, which Nvidia CEO Jensen Huang promised will be a “big, big, huge step up,” over the current-gen Blackwell chips. This represents the cutting edge of AI computing technology, designed specifically for the massive scale of modern AI training and inference workloads.

Average power densities have more than doubled in just two years, to 17 kilowatts (kW) per rack, from eight kW, and are expected to rise to as high as 30 kW by 2027 as AI workloads increase. Training models like ChatGPT can consume more than 80 kW per rack, while Nvidia’s latest chip, the GB200, combined with its servers, may require rack densities of up to 120 kW.

These technical specifications highlight the engineering challenges involved in building AI infrastructure at this scale. The power requirements necessitate advanced cooling systems, specialized electrical infrastructure, and careful facility design to handle the heat generated by millions of high-performance processors operating continuously.

Sustainability and Energy Challenges

The environmental implications of such massive computing infrastructure cannot be ignored. Most electrical grids around the world are still heavily reliant on fossil fuels. One preprint study from Harvard’s T.H. Chan School of Public Health found that the carbon intensity of electricity used by data centers was 48% higher than the US average.

“AI data centers need constant power, 24-7, 365 days a year,” says Rahul Mewawalla, the CEO of Mawson Infrastructure Group, which builds and maintains high-energy data centers that support AI. “That means data centers can’t rely on intermittent technologies like wind and solar power”.

However, the scale of these projects is also driving innovation in sustainable energy solutions. The scale of a nuclear power plant is on par with that of a data center campus based on cost per megawatt of IT load. Carbon emissions from nuclear power are low, which aligns with the stated ambitions of most data center operators, suggesting that nuclear power could play a significant role in powering the AI infrastructure of the future.

Industry Perspective and Leadership Vision

The partnership reflects the vision of both companies’ leadership for the future of artificial intelligence. “NVIDIA and OpenAI have pushed each other for a decade, from the first DGX supercomputer to the breakthrough of ChatGPT,” said Jensen Huang, founder and CEO of NVIDIA. “This investment and infrastructure partnership mark the next leap forward — deploying 10 gigawatts to power the next era of intelligence.”

OpenAI CEO Sam Altman emphasized the foundational importance of computing infrastructure, stating: “Everything starts with compute. Compute infrastructure will be the basis for the economy of the future, and we will utilize what we’re building with NVIDIA to both create new AI breakthroughs and empower people and businesses with them at scale.”

This partnership represents more than just a business deal – it’s a bet on the future architecture of the digital economy, where AI capabilities become as fundamental as electricity or internet connectivity.

Looking Forward: The Path to Superintelligence

The partnership aims to support OpenAI’s path toward developing superintelligence capabilities, representing one of the most ambitious technological goals of our time. The infrastructure being built through this partnership will support not just current AI applications, but the next generation of AI systems that could transform every aspect of human activity.

As this historic partnership moves forward, it signals a new phase in the AI revolution – one where the physical infrastructure needed to support artificial intelligence becomes as important as the algorithms themselves. The success or failure of this massive undertaking will likely influence the trajectory of AI development for decades to come, making it one of the most significant technology investments of the 21st century.

The Nvidia-OpenAI partnership stands as a testament to the scale of ambition driving the AI revolution and the infrastructure required to turn that ambition into reality. As both companies work to finalize the details in the coming weeks, the technology industry and the world will be watching closely to see how this unprecedented collaboration shapes the future of artificial intelligence.
