The world’s largest technology companies are pouring money into artificial intelligence at a pace that is beginning to rival one of the most capital-intensive industries on Earth and the gap is closing fast.
Amazon, Alphabet, Microsoft, and Meta collectively committed to spending as much as $364 billion across their 2025 fiscal years on AI-related infrastructure data centers, semiconductors, cloud platforms, and AI systems.
In 2026, those four companies are expected to spend nearly $700 billion combined, a rise of more than 60% from already historic 2025 levels.
That figure is now breathing down the neck of the entire global oil and gas upstream sector.
According to the International Energy Agency, overall upstream oil and gas investment for 2025 is expected to come in at just under $570 billion, a decline of around 4% from the prior year.
Upstream oil investment specifically is set to fall 6% to around $420 billion in 2025.
Put simply: four technology companies are on track to outspend the entire global oil and gas exploration and production industry.
An Arms Race With No End in Sight
The scale of the spending is difficult to overstate.
Last year alone, Meta, Alphabet, Amazon, and Microsoft spent more than $400 billion in capital expenditure, most of it directed toward data centers, the physical backbone of all AI applications.
That figure is more than double what the same group spent in 2023.
The acceleration shows no sign of slowing. By late 2025, these companies were spending over $140 billion per quarter combined.
Individual commitments are staggering on their own: Amazon has said it expects to spend $200 billion in 2026 alone.
The pressure is competitive as much as it is strategic.
With each announcement of another increase in capital expenditure, rivals face mounting pressure to match it creating a spending spiral that nobody wants to risk falling behind in.
Even companies that had previously signaled restraint are reversing course.
Microsoft CFO Amy Hood confirmed on an earnings call that capex growth would accelerate in fiscal 2026, after the company had previously suggested growth would slow.
Capex rose 45% to $64.55 billion in the last fiscal year.
Meta has been equally aggressive. Its CFO Susan Li stated that capital expenditures which have already nearly doubled year-on-year to $72 billion will grow “notably larger” in 2026.
When asked about capital allocation priorities, Li responded that the company’s “highest priority is investing our resources to position ourselves as a leader in AI.”
Oil and Gas: Still Essential, But Losing the Race for Capital
The oil and gas industry, by contrast, is under pressure from multiple directions.
Lower expenditure on oil has driven the first year-on-year decline in upstream investment since the COVID slump in 2020, and the largest since 2016.
Upstream oil and gas investment has fallen 35% over the past decade, from $869 billion in 2015 to $567 billion in 2025. Despite that, the sector still requires enormous sums just to stay still.
Nearly 90% of annual upstream investment is dedicated not to growing supply, but simply to offsetting production declines at existing fields.
The IEA has warned the stakes are significant. If investment were to stop entirely, annual supply losses would equal the combined production of Brazil and Norway around 5.5 million barrels per day.
The Debt Machine Behind the AI Build-Out
The sheer scale of tech spending is now forcing some of the world’s most profitable companies to tap debt markets.
Meta and Oracle issued $75 billion in bonds and loans in just September and October 2025 alone to fund AI data center construction more than double their annual average over the past decade.
Meta’s single bond deal totalled $30 billion, the largest investment-grade corporate bond deal of the year.
The financial strain is showing up in free cash flow projections. Amazon is looking at negative free cash flow of nearly $17 billion in 2026, according to Morgan Stanley analysts.
Alphabet’s free cash flow is projected to fall almost 90% this year, to $8.2 billion from $73.3 billion in 2025, according to Pivotal Research.
Roughly 75% of the $600 billion-plus in hyperscaler capex expected in 2026 is directly tied to AI infrastructure servers, GPUs, data centers, and networking equipment rather than traditional cloud expansion.
A Structural Shift in Global Capital
The numbers reflect something deeper than a technology boom. They point to a fundamental reordering of where the world’s capital goes.
IEA Executive Director Fatih Birol put it plainly: “Ten years ago fossil fuel investment was higher than investment in electricity. Now, it is exactly the opposite.”
AI is accelerating that trend. Data centers require enormous amounts of electricity.
Natural gas investment has actually increased in 2025 to meet strong demand from data centers, one of the few places where AI spending is actively pulling fossil fuel investment upward rather than displacing it.
The five largest hyperscalers have plans to add around $2 trillion of AI-related assets to their balance sheets by 2030.
Oil and gas will remain essential to global energy supply for decades to come.
But as a destination for new investment dollars, the industry is losing ground and quickly to a technology sector that is spending at a pace the energy world has rarely seen.
