SEOUL, May 14 (AJP) -The software was written in California. The intelligence is being manufactured in Asia.
A Bloomberg chart circulating this week tells the story cleanly: South Korea has overtaken the United Kingdom to become the world's eighth-largest stock market, at $4.04 trillion. Six of the ten largest equity markets on Earth now sit in Asia.
The United States ushered the generative AI era. But the East building its physical infrastructure is collecting the dividend.
This is not a coincidence. It is the logical consequence of how artificial intelligence actually works.
Every AI query, response, every generated image begins not with software but with hardware: electrons moving through silicon, copper, and exotic materials assembled to nanometer tolerances. That supply chain runs through Asia. Understanding how each major market fits into it reveals not a single AI boom but four distinct ones, each feeding into the next.
Taiwan: The Indispensable Foundry
Without TSMC, there is no AI at scale. The pure-play foundry controls more than 90% of the world's leading-edge chip production.
Nvidia's Blackwell GPUs, AMD's MI series, Apple's M-chips — all fabbed in Taiwan.
In Q1 2026, TSMC reported revenue of $35.6 billion, up 35% year-on-year, with profit jumping 58%. Capital expenditure for 2026 is guided at $52–56 billion, a 37% increase, signaling management sees no demand ceiling. Goldman Sachs estimates Taiwan's market is "well over 80%" exposed to AI-related revenue. TSMC's largest customers are collectively planning over $1.2 trillion in data center capex through 2028. Almost all of it flows through Hsinchu.
South Korea: The Memory Monopoly
If Taiwan is the foundry, South Korea is the memory bank — and in AI, memory is no longer a commodity. It is a chokepoint.
High-Bandwidth Memory, or HBM, sits alongside AI processors and feeds them data at speeds standard DRAM cannot approach. The world's HBM comes overwhelmingly from two companies in Gyeonggi Province. SK Hynix beat Samsung in operating profit for the first time in 2025, posting a record 47.2 trillion won for the year. Its stock rallied more than 210%.
The KOSPI has gained nearly 80 percent in just five months into the year to become the world's best-performing major index.
SK hynix holds a 57–62% share of the global HBM market, supplies Nvidia almost exclusively, and has already sold out its entire 2026 capacity.
The Bank of America calls 2026 a "memory supercycle similar to the boom of the 1990s," projecting the HBM market to reach $54.6 billion — up 58 percent year-on-year.
The stock rally however goes broader than memory. Investors have poured into shipbuilding, defense, power equipment, and cultural exports.
HD Hyundai Electric, LS Electric, and Hyosung Heavy Industries carry order books extending years forward as AI data centers drive unprecedented electricity demand.
Goldman Sachs has noted Korea's market is "deeper and broader" than Taiwan's — a rare thing to say about a market whose memory champions alone have rewritten the rules of the semiconductor industry.
Japan's role sits one layer upstream: the machines that make the chips.
Tokyo Electron, Advantest, and Lasertec supply the lithography tools and test equipment that TSMC and SK Hynix depend on to scale.
The Nikkei 225 crossed 60,000 for the first time in history on April 23, 2026. On May 7, markets reopened after Golden Week and immediately priced in a global AI rally that had run in their absence — the index surged 5.58 percent, its largest single-day point gain ever, led by SoftBank (+18.44%), Tokyo Electron (+9%), and Advantest (+7%). J.P. Morgan has set a year-end 2026 Nikkei target of 70,000.
SoftBank deserves a sentence of its own. Once mocked for Vision Fund losses, Masayoshi Son's bets on Arm Holdings and OpenAI have made the company, in the words of one analyst, "the listed proxy for OpenAI and Arm." Japan's decades of stagnation have found, in AI infrastructure demand, a genuine secular growth engine.
China and Hong Kong: The Challenger Ecosystem
China's position is the most contested and the most consequential to watch.
Blocked from advanced Nvidia chips since 2022, Chinese companies have responded by building a parallel AI ecosystem.
DeepSeek's R1 model, released in January 2025, claimed performance comparable to OpenAI's best systems at a fraction of the cost — and rattled global markets. The Hang Seng Tech Index surged nearly 30 percent in the weeks that followed.
Alibaba, which has pledged $52 billion over three years in AI infrastructure, added $153 billion in market value from its January 2025 lows. Chinese chipmakers SMIC and Hua Hong Semiconductor have rallied as Beijing backs semiconductor self-sufficiency with incentives reportedly worth up to $70 billion.
The valuation case is straightforward: Hang Seng Tech trades at roughly 24 times forward earnings versus 25–31 times for the Nasdaq 100. UBS rates Chinese tech "most attractive," citing rapid AI monetization and policy support. The U.S. built the leading models; China is building a parallel ecosystem around them.
There is a layer beneath the semiconductors that deserves attention: the power grid itself.
AI data centers consume electricity at two to five times the rate of conventional facilities, creating a global shortage of high-voltage transformers, cables, and switchgear — equipment made disproportionately in Asia.
Korea's HD Hyundai Electric dominates ultra-high-voltage transformer supply for North America. LG Energy Solution and Samsung SDI supply large-scale battery storage systems stabilizing AI campus power grids. Japan's Fujikura, a cable specialist, has been among the surprise winners of the infrastructure buildout.
Every kilowatt delivered to a GPU cluster passes through equipment increasingly likely to carry an Asian manufacturer's nameplate.
The structural thesis is simple. AI is a software product requiring a hardware supply chain of extraordinary complexity. The software came from the United States. The hardware supply chain is Asian — from the foundries of Taiwan to the memory fabs of Korea, from Japan's equipment makers to China's challenger chipmakers, down to the transformers and cables that keep the whole system powered.
The intelligence was born in California. The factory floor is in Asia.
