A research team at UBS has identified an “extraordinary” shift in the technology landscape: value creation in the artificial intelligence infrastructure sector has surged 600% over the past four years. By contrast, the hyperscalers — the largest cloud and data-center operators — managed only 100% growth in the same period.
The finding underscores a rotation in investor focus away from the dominant tech giants and toward the physical backbone of AI. Raw computing power, specialized chips, and energy-intensive data centers are now capturing capital that once flowed exclusively to software and platform companies. The UBS team described the divergence as unprecedented.
According to the bank’s analysis, the 600% figure reflects aggregate value creation across a basket of AI infrastructure stocks. These include firms providing networking equipment, semiconductor manufacturing, cooling systems, and power management for AI workloads. The 100% gain for hyperscalers places them well behind the infrastructure cohort in relative terms.
The data suggests that the AI buildout has entered a capital-intensive phase. Companies building and supplying the physical layer of AI — rather than just the applications — are reaping disproportionate rewards. This shift may continue as demand for compute capacity shows no signs of slowing.
The report does not specify which stocks are included in the infrastructure basket, limiting granular comparison. UBS did not provide forward guidance on whether the trend can sustain its current pace.
