PwC has projected that cumulative global capital expenditure dedicated to artificial intelligence infrastructure will reach $31.6 trillion through 2050, driven by the escalating demand for high-performance computing capacity worldwide.

According to the analysis, yearly capital spending allocated to data centres is anticipated to surge substantially over the next quarter-century. Outlays are forecast to rise from approximately $800 billion annually in 2026 to around $1.8 trillion per year by 2050.

The long-term investment profile will be predominantly shaped by hardware refresh cycles rather than initial construction projects. The report indicates that recurring replacements and modernisations of semiconductor chips will constitute the vast majority of long-term capital deployment.

Alongside semiconductor refresh demands, power requirements are expected to serve as a pivotal factor governing the scale and pace of global computing expansion through 2050.
