Four companies have now spent more than a trillion dollars building the physical backbone of artificial intelligence.
According to the Financial Times, Google, Amazon, Microsoft and Meta together spent $1.1 trillion in capital expenditure from the start of the AI boom in 2023 through June 2026 — and they plan to spend $745 billion this year alone. As the FT put it, the four have vastly increased their investments since the boom began in 2023.
Capital expenditure, or capex, is the money a company spends on long-lived physical assets. In this case that means data centers, power infrastructure and the chips that fill the racks. It is spending you can walk through, not a line of software.
The latest push came from Amazon. As reported in coverage carried by MSN, Amazon raised its full-year capex forecast on Thursday to $220 billion, up from a previous estimate of $200 billion, with Chief Executive Officer Andy Jassy saying most of that spending will go toward AI. That report framed Amazon and Microsoft doubling down as a relief for the chip sector, which had faced concerns about whether the buying would hold up.
The scale here is the story. Very few entities of any kind — companies or governments — commit sums like this to a single technology bet over a few years, and the spending is concentrated among a handful of firms. That concentration is exactly why chipmakers and their suppliers watch these forecasts so closely: when four customers account for so much demand, a single revised number moves an entire industry.
It matters because a trillion dollars of steel, silicon and electricity is a wager that AI demand will keep growing for years, and the companies making it have now tied their finances — and the fortunes of everyone who supplies them — to that bet being right.
