The Most Expensive Bet in Tech History

Amazon said on Thursday it would invest about $200 billion in capital expenditures in 2026, an announcement that followed Alphabet telling investors on Wednesday its capex would fall between $175 billion and $185 billion this year. Late last month, Meta told investors it would spend anywhere from $115 billion to $135 billion in 2026, while Microsoft's annual run rate for its 2026 fiscal year, which began in July, would put the company on pace for capital expenditures of $145 billion.

The aggregate number is staggering: At the low end of that range, the four would spend about $635 billion, marking a roughly 67% spike from the companies' $381 billion in expenditures in 2025. At the high end of their guidance, the group would spend around $665 billion, or a 74% jump from the previous year.

The vast majority of that spending will go to AI chips, servers, and data center infrastructure, the companies said. But here's the uncomfortable truth: Investors are placing more scrutiny than before on how tech giants are generating returns on their investments in AI infrastructure, as fears of a market bubble mounted in the latter half of 2025.

My assessment: This spending is not discretionary—it's existential. If one company pulls back and another doesn't, the laggard loses the AI race. It's a trillion-dollar game of chicken. The market's nervousness isn't about whether the spending is necessary; it's about whether the returns will ever justify it. That's the real question that won't be answered for 3-5 years.
