Data Centers Just Outspent Big Oil.

Data center capital expenditure reached $770 billion in 2025 — surpassing investments in upstream oil and gas for the first time. Solar photovoltaic, widely considered the biggest energy supply growth story of the past decade, had already been overtaken by data centers in 2024. This year, Rystad Energy expects data center investments to match both the entire renewable generation industry and the full oil and gas sector — upstream, midstream, and downstream — combined.

That is not an evolution of the tech sector. That is a reordering of capital markets.

What $770 Billion Buys

Forty percent of that spend goes to IT infrastructure — accelerator servers, networking, storage. But the other 60% — cooling systems, power distribution, backup generation, grid interconnection — is nearly equal to the entire global solar PV sector. And those are just the direct costs. The knock-on investments in new generation assets, grid upgrades, and supply chains add hundreds of billions more.

This is infrastructure on the scale of the Industrial Revolution. The difference: data centers get built in months, not decades.

Megawatts, Not Megabytes

The asset class itself is transforming. Data centers above 100 megawatts are becoming the dominant form factor — infrastructure-grade facilities that demand utility-level power delivery with startup-speed timelines. This is not a server closet anymore. It is a power plant that happens to compute.

The money is concentrated in hyperscalers — Google, Amazon, Microsoft, Meta — and a handful of frontier AI labs and global operators. The capital structure mirrors upstream oil and gas, where majors and national oil companies dominate. But the risk profile is inverted: oil exploration takes decades to pay back; AI infrastructure pays back in quarters, if the models work. If they don't, the stranded assets are measured in billions.

The Geography of Compute

The US accounts for 42% of installed capacity — twice that of China, the second-largest market. India sits third. But that distribution is shifting. As power demand from data centers exceeds 10% of national grids in many countries, constraints on power, land, and interconnection are pushing operators to new markets. By 2030, expect strong growth in Finland, Portugal, and Thailand — countries that would never have figured in industrial-era infrastructure calculus.

The energy implications are the story nobody is following closely enough. In a world where the Strait of Hormuz crisis has oil at $104 and climbing, the same capital that built the AI boom is now reshaping global energy markets from the demand side. Data centers have graduated from consumer to market-maker.

The Equipment Boom

The beneficiaries are already visible. Siemens Energy's share price has rallied 10x since January 2024. Bloom Energy, a solid oxide fuel cell manufacturer, has grown at a similar pace. Mitsubishi Heavy Industries is up 6x. GE Vernova has doubled since January 2025 alone. The equipment supply chain — gas turbines, transformers, fuel cells, grid hardware — is experiencing demand growth that only oil booms have historically generated.

But this growth carries its own risk. Supply chain delays, grid interconnection bottlenecks, and equipment shortages will not resolve in the next few years. Prices will spike. The sector needs oil-and-gas-scale revenue to sustain this investment level — and with new AI applications emerging weekly, the supercycle shows no sign of cooling.

What This Actually Means

The narrative around AI has been dominated by software: agents, models, interfaces, tools. But the underlying reality is physical. The thing making AI possible is not a better transformer architecture — it is concrete, copper, cooling towers, and the grid capacity to power a small city.

Every AI breakthrough is, underneath, an energy breakthrough. And the capital markets have figured this out before most analysts have. Data centers are now not just customers of the energy sector — they are co-authors of its future.
