South Korea has just placed the biggest wager of the artificial intelligence era, and the number is hard to ignore. The country’s South Korea $880 billion AI chip plan, unveiled in Seoul on Monday by President Lee Jae-myung, commits at least that much (roughly £666 billion) over the coming decade to semiconductors, AI data centres and what officials are calling physical AI. Bloomberg pegged the combined corporate and state figure at around 1,350 trillion won. To put it in perspective, that is close to five percent of the nation’s entire 2024 economic output, poured into chips and the machines that crave them.
Lee did not bother with modesty. Flanked by the heads of Samsung Electronics and SK Hynix, whom he warmly branded “national heroes,” he framed the package as a matter of survival rather than ambition. “We must secure the core elements of AI faster than any other country,” he said, before adding the line that became the day’s unofficial motto, “Speed is the only way to survive.” He nicknamed the blueprint the “Three Mega Projects” and described semiconductors, physical AI and AI data centres as the “triple axis for a great leap forward.”

Where the money actually goes
The bulk of the cash is memory, and lots of it. Samsung and SK Hynix, alongside suppliers, will spend about 800 trillion won (close to $518 billion) on memory chip manufacturing, building two new fabrication plants each in the country’s southwest. A separate chip-packaging cluster in the Chungcheong region near Seoul draws roughly 81 trillion won (about $52.5 billion), with high-bandwidth memory packaging concentrated around Cheonan, Onyang and Cheongju.
Then there are the data centres. Backed by the SK Group, GS Group and Naver, around 550 trillion won (some $356 billion) is earmarked for AI computing capacity. By 2035, the government wants total data centre power to exceed 18.4 gigawatts, lifting the all-in national tally past one quadrillion won. The plan dwarfs South Korea’s earlier chip blueprints, including a $450 billion effort from 2021 and a $400 billion one from 2023.
Why now, and why everyone is spending
The timing is no accident. Memory has stopped being a sleepy commodity and turned into the hottest asset in tech. DRAM contract prices have climbed somewhere between 50 and 90 per cent across recent quarters, with some analysts cheerfully calling the squeeze “RAMmageddon.” The reason is simple. Samsung, SK Hynix and Micron, who together control more than 95 percent of global DRAM, have redirected wafers toward high-bandwidth memory for AI accelerators, starving phones and laptops of the cheaper stuff.
Demand is coming from familiar giants. Microsoft, Google, Amazon and Meta are collectively expected to spend around $650 billion on AI infrastructure in 2026, and every Nvidia GPU they buy swallows enormous quantities of memory. The fallout has already reached shop shelves, with Apple, Microsoft and major PC makers nudging prices upward as components grow scarce.
The regional contest sharpens the picture. The United States keeps funnelling money through its CHIPS Act, China is reportedly drafting an AI buildout worth about $295 billion, and Japan continues lifting chip subsidies. Seoul clearly does not want to be the one standing still.
A national bet wrapped in a political fight
Not everyone is applauding. The decision to plant a second semiconductor cluster in the Honam region, around 165 miles south of Seoul and a traditional stronghold of Lee’s ruling Democratic Party, has lit a political fire. Opposition figures called it “the worst form of political intervention,” arguing that two rival conglomerates announcing huge investments in the same place at the same time smells of pressure rather than free choice. Critics in Daegu, North Gyeongsang and Chungcheong piled on, questioning whether the area even has enough water, power and skilled workers.

Lee pushed back hard, firing off a string of posts on X over a weekend. He pointed out that South Jeolla and Gwangju scored highest in a 2023 evaluation of semiconductor complex sites, and that the southwestern coast sits on rich, largely untapped renewable energy resources. Markets, meanwhile, reacted with a shrug bordering on a wince. Samsung shares slid nearly five percent and SK Hynix slipped further, as investors weighed the risk of future oversupply should AI demand ever cool.
There is also the uncomfortable truth that money alone does not conjure a fab. As one KAIST professor noted, the plan still needs power, water, talent and flawless execution, four things that cannot be ordered in bulk. Samsung’s Jay Y. Lee summed up the mood neatly, calling it “a race against time.”
Final Thoughts
For all the eye-watering zeros, the most interesting part of this plan is not the spending; it is the geography. Seoul is essentially trying to prove that an AI gold rush can lift the whole country rather than one glittering capital. That is a genuinely fresh idea in a race that usually rewards concentration over fairness. Whether the southwest can deliver the water and watts to match the won is the real cliffhanger. If it works, South Korea will not just defend its memory crown; it will hand the rest of the world a blueprint for spreading AI wealth around. If it stumbles, it becomes a very expensive lesson in why chip fabs follow rivers and power lines, not election maps.
