Big tech spends more than $1 trillion on AI infrastructure — additional $745 billion expected to be added to the figure in 2026 alone

Amazon, Google, Meta, and Microsoft have collectively spent over $1.1 trillion on AI infrastructure since 2023, according to the latest earnings reports from the Financial Times. Analysts predict an additional $745 billion will be added to this figure just this year. The data center cooling state of play is a significant bottleneck for AI development, and massive AI data center buildouts are placing strain on energy supplies.

These investments have also affected other industries, such as electricity prices, memory and storage chips, and the environment. The White House has implemented measures like the "ratepayer protection pledge" to protect consumers from electricity cost increases, but no state has yet codified this promise into law. The spending spree on AI has also impacted the memory and storage chip industry, leading to a shortage of consumer memory that began in 2025 and has since expanded to affect other industries like cars and smartphones.

While the big four's massive CAPEX (capital expenditure) might appear excessive, their companies generate substantial quarterly revenues, raising questions about the sustainability of their spending.
