Where global economies sit in the AI stack

Artificial intelligence is evolving from a US-led race in model development into a global buildout of infrastructure, hardware and real-economy applications. China, South Korea and Japan are emerging as key nodes in this new phase, leveraging strengths in manufacturing, industrial automation and semiconductor supply chains rather than competing solely on frontier models.

Taiwan’s dominance in advanced chip production, alongside South Korea’s leadership in memory and Japan’s depth in materials and precision equipment, anchors the hardware layer that enables AI at scale. At the same time, energy-rich markets such as Brazil and Saudi Arabia are positioning themselves as critical providers of clean power and data center capacity for AI workloads.

For investors, these shifts argue for a broader view of AI exposure that extends beyond US software leaders to include global industrials, hardware suppliers and energy-enabled infrastructure plays.
