Summary
The "multi-trillion dollar AI infrastructure buildout" represents an unprecedented global investment aimed at establishing the foundational components for the burgeoning field of artificial intelligence. This includes the development of advanced computing hardware like AI chips and GPUs, the construction of specialized "AI factories" (data centers), and significant enhancements to energy systems. Key industry leaders such as Lisa Su of AMD and Jensen Huang of Nvidia are driving the production of essential AI chips and technologies like the Hopper GPU and CUDA software, which form the core of the American tech stack. The initiative also focuses on securing domestic supply chains for critical materials, exemplified by MP Materials' role as the sole U.S. producer of rare earths for physical AI technologies, bolstered by public-private partnerships like the MP Materials-DoD deal to reduce reliance on foreign sources. A major challenge is the escalating energy consumption required for AI, necessitating substantial new energy investments. This massive buildout is seen as a reindustrialization effort for the United States, aiming to create a robust and self-sufficient AI ecosystem, with cumulative global investments projected to reach several trillion dollars by 2035, comparable in scale to World War II mobilization.

- The Largest Capital Formation in History — AI and AI Infrastructure
The period from now through 2035 is poised to witness one of the greatest infrastructure buildouts in history, centered on enabling AI. Trillions will be spent across semiconductors, data centers, and energy systems. For infrastructure investors, this is a multi-faceted opportunity: from financing the next generation of chip fabs and energy-efficient data centers, to investing in power grids and cooling systems, to backing the platform companies that turn all this capital into profitable AI [...] Bringing these pieces together, the cumulative global investment in AI infrastructure could reach several _trillion_ dollars by 2035. Estimates vary widely, but all signal an unprecedented wave of capital formation. McKinsey concluded that scaling AI data centers will require “more than a trillion dollars” by 2030 in infrastructure ecosystem spend. A recent scenario analysis by CSIS found that in a fast-adoption case, _cumulative_ capex on generative AI data centers could hit $2.35 trillion by [...] World War II Mobilization: The only historical mobilizations that rival AI in sheer dollars are world wars. U.S. military spending in WWII is estimated around $4 trillion in today’s terms. The global AI buildout, projected in the $5+ trillion range, is on par with World War II-level expenditure, albeit spent over a longer period and without the destructive aspects of war. It’s truly striking that a peacetime tech rollout may command multi-trillion-dollar resources akin to a world war
- Can US infrastructure keep up with the AI economy? - Deloitte
The changing scope and scale of infrastructure development have likewise increased the investment stakes of building out capacity for data centers, power generation, and manufacturing to trillion-dollar levels. [...] The tech industry has also announced plans to invest more than a trillion dollars in US manufacturing of AI supercomputers, chips, and servers over the next four years.47 [...] The new level of funding reflects confidence that trillion-dollar AI applications and returns will materialize. Fears that cheaper models could undermine hyperscalers’ business model have sparked market volatility. But they have not impacted hyperscaler AI chip purchases and capex forecasts.48Rather, hyperscalers have shifted investment from AI training towards inference.49 ### Strategy 5: New business models to drive infrastructural efficiency, capacity, and flexibility
- IIIa. Racing to the Trillion-Dollar Cluster - SITUATIONAL AWARENESS
SITUATIONAL AWARENESS The Decade Ahead # IIIa. Racing to the Trillion-Dollar Cluster The most extraordinary techno-capital acceleration has been set in motion. As AI revenue grows rapidly, many trillions of dollars will go into GPU, datacenter, and power buildout before the end of the decade. The industrial mobilization, including growing US electricity production by 10s of percent, will be intense. In this piece: [...] A new TSMC Gigafab (a technological marvel) costs around $20B in capex and produces 100k wafer-starts a month. For hundreds of millions of AI GPUs a year by the end of the decade, TSMC would need to build dozens of these—as well as a huge buildout for memory, advanced packaging, networking, etc., which will be a major fraction of capex. It could add up to over $1T of capex. It will be intense, but doable. (Perhaps the biggest roadblock will not be feasibility, but TSMC not even trying—TSMC does [...] ### Historical precedents $1T/year of total annual AI investment by 2027 seems outrageous. But it’s worth taking a look at other historical reference classes: $1T/year of total AI investment by 2027 would be dramatic—among the very largest capital buildouts ever—but would not be unprecedented. And a trillion-dollar individual training cluster by the end of the decade seems on the table.12 ### Power

- Executive summary – Energy and AI – Analysis - IEA
In the past few years, AI has gone from an academic pursuit to an industry with trillions of dollars of market capitalisation and venture capital at stake. The market capitalisation of AI-related firms in the S&P 500 has grown by around USD 12 trillion since 2022. While there are several uncertainties about its uptake and impact, AI’s rapid development and huge potential have made it central to corporate strategies, economic policies and geopolitics. [...] #### Data centres account for a small share of global electricity consumption today, but their local impacts are far more pronounced Global investment in data centres has nearly doubled since 2022 and amounted to half a trillion dollars in 2024.This investment boom has led to growing concerns about skyrocketing electricity demand. [...] There are uncertainties in how quickly AI will be adopted, how capable and productive it will become, how fast efficiency improvements will occur, and whether bottlenecks in the energy sector can be resolved.These uncertainties are explored in sensitivity cases. A Lift- Off Case assumes higher rates of AI uptake and proactive action to reduce energy sector bottlenecks. A Headwinds Case incorporates bottlenecks – including macroeconomic headwinds – in the uptake of AI and the buildout of energy
