Big Tech’s AI infrastructure spending is climbing to new highs in 2026, with Alphabet, Amazon, Meta, and Microsoft forecasting about $650 billion in combined capital expenditures for data centers and equipment. That spending wave is now colliding with a second boom in the power sector, as US investor-owned utilities are projected to spend $1.4 trillion on capital expenditures by 2030 to meet electricity demand from AI and modernize the grid.
The scale of the buildout stands out even by historic standards. Bloomberg reported that the planned spending by the four tech companies has no parallel this century, and each company’s 2026 estimate is expected to be near or above its budgets for the prior three years combined. The estimated total is about 60% higher than a year ago, pointing to another acceleration in data center construction around the world.
That rapid expansion is not just a story about Silicon Valley budgets. Utilities say training and using AI requires massive amounts of electricity, and Business Insider reported that spending on new power plants and transmission lines has reached record highs as companies try to serve data center customers while upgrading an aging grid. Together, the two trends show how the AI race is spreading far beyond chipmakers and software firms and into the physical systems that keep digital services running.
Tech Giants Lift Spending Plans
Amazon plans $200 billion in capital expenditures for 2026, while Alphabet expects to spend as much as $185 billion. Meta said full-year capital spending could reach $135 billion, a potential jump of about 87%, and analysts projected Microsoft would spend almost $105 billion for its fiscal year ending in June after a 66% increase in second-quarter capital spending. Bloomberg said those outlays would mark the biggest capital spending by any single corporation in any one of the past 10 years.
Much of that money is aimed at building new data centers and filling them with the hardware needed to run AI systems. Bloomberg said the rush has already created bottlenecks in key inputs, including electricians, cement trucks, and Nvidia chips produced by Taiwan Semiconductor Manufacturing Co. factories. The report also said the buildout has touched off an unprecedented level of borrowing, with AI-related companies and projects tapping debt markets for at least $200 billion last year, a figure described as likely an undercount because many deals are private.
The investment push is also reshaping the companies making the bets. Bloomberg reported that Meta spent more on capital projects than research and development last year for the first time in six years, and the company ended the year with $176 billion in property and equipment, about five times its total at the end of 2019. For all four companies, the spending rests on the view that tools like ChatGPT and rival AI systems will play a growing role in work and home life.
Utilities Race to Keep Up
Utilities are responding with a spending surge of their own. A PowerLines study cited by Business Insider said investor-owned utilities are on track to spend $1.4 trillion by 2030, more than the $1.3 trillion the industry reported spending over the last decade. The analysis of 51 utility earnings calls found that much of the increase is concentrated among a relatively small group of companies.
Duke Energy leads the list with planned capital expenditures of $102.2 billion by 2030, followed by Southern Company at $81.2 billion and American Electric Power at $72 billion. Business Insider said Duke serves customers in Florida, Indiana, Ohio, Kentucky, North Carolina, and South Carolina, where electricity demand is rising because of data centers. Southern serves data center projects tied to a Meta campus in Huntsville, Alabama, and Microsoft’s growing network in Georgia, while AEP battled the data center industry over a proposed tariff in Ohio before regulators approved it in July.
Pressure on Customers and Investors
The boom is also intensifying questions about who pays for all this infrastructure. Business Insider reported that electric and gas utilities sought to raise customer bills by $31 billion in 2025, more than double the amount sought in 2024. That has fueled a national debate over whether households and other customers should help cover the cost of the AI buildout.
Bloomberg also said the data center expansion has pinched energy supplies and brought developers into conflict with communities worried about rising power and water costs. Investors have shown more caution as spending rises, and Bloomberg reported that the four tech companies together lost more than $950 billion in market value after their latest earnings and outlooks. Last month, Microsoft, Meta, and OpenAI were among the tech companies that signed President Donald Trump’s Ratepayer Protection Pledge, a voluntary agreement intended to keep data center power costs from pushing up consumer electricity bills.
