Four US companies are set to spend a combined $650 billion on AI in 2026.
In a swift, aggressive race to dominate the AI sector, four of the biggest US tech companies have placed huge bets on AI spending this year. Bloomberg reports that Alphabet, Amazon, Meta, and Microsoft will spend a staggering $650 billion on AI this year.
The report also indicates that the money isn’t just for all things AI, but specifically for expanding their data center reach. It’s not surprising, as having more data centers correlates with having more computing power for advanced AI capabilities.
Big bets in the pursuit of global AI dominance
The four big techs and other companies spending heavily on AI all want one thing: a large share of the AI market.
Competition is growing from new AI startups scaling fast to older, more established companies pivoting to AI. The result is an even tougher playground for AI-focused companies, and potentially other software companies.
Bloomberg estimates suggest each company’s projected budget is far higher than what they spent on AI in the last few years.
Bloomberg also analyzed the expected expenditure of 21 other companies from different industries. Results from the analysis revealed that combined, their $180 billion 2026 budget doesn’t come anywhere close to the $650 billion planned by the four big tech firms.
The group of 21 includes companies from huge US industries, such as automaking, construction equipment, and defense contractors. Even with major names like Exxon Mobil Corp., Intel Corp., and Walmart Inc. in the mix, their projected spending is dwarfed by the AI bets of these four tech giants.
An ironic drop in value plus investors’ unease
Despite this spending, which should ideally signal rising AI potential, investors are rather worried.
Questions about potential profitability that would justify the spend are surfacing. Google, for instance, which generates most of its revenue from advertising, plans to spend as much as $185 billion. Amazon, on the other hand, plans to spend up to $200 billion. Investors are concerned that these expenditures may be excessive relative to profits, despite these companies’ large cash reserves.
The Bloomberg report also shows that another factor causing the unease is concern about how AI may affect other software companies not focused on AI.
Tomasz Tunguz, an ex-Google employee turned investor, wrote in a blog last year that these kinds of scenarios often end badly, but while they last, they are economically beneficial. That may explain why these investors are not just worried, but pulling money out of these companies. The negative sentiment among these investors has led to a combined loss of over $950 billion following the companies’ announcements.
Where the big four are now focused
The four companies are not only building LLM chatbots or replacing employees with AI. They are all focused on a tough battle to dominate AI compute production.
Data centers power all the forms of AI we see around us, and the company with more of them and that does it better will emerge as the winner. That simple fact has driven the frenzy to build more data centers, despite their environmental impact.
Elon Musk has already announced plans to set up data centers in space. Elon claims that having data centers in space leverages the Sun’s infinite energy, space’s vastness, and other resources to create high-efficiency data centers that will produce advanced AI models.
If this comes to fruition, SpaceX, which recently merged with xAI, could outpace these four in the race… or push them to double down on that path too.
