South Korea’s semiconductor and AI investment plan unveiled Monday commits $518B to four new memory fabs in the southwest, adds $52B for an HBM packaging hub, and sets aside $356B for AI data centers through 2035. With President Jae Myung Lee warning that exis
The room was full of weight—Samsung and SK Hynix chairmen included—when South Korea rolled out a national push aimed straight at the memory shortage driving the age of AI.
Monday’s presidential briefing didn’t just announce more construction. It laid out numbers built to change the supply chain itself: $518 billion (about 800 trillion won) to build four new memory fabs in the southwest. plus $52 billion for an HBM (high bandwidth memory) packaging hub in the central region. The plan also includes $356 billion (550 trillion won) for AI data centers. to be built by Korean tech and energy groups such as SK. GS and Naver through 2035.
In total. South Korean tech companies have committed to spend over $900 billion on AI and on the chip demand it is creating—an effort the country hopes will move it from major AI player to something stronger. It’s a direct attempt to ride what the world has started calling “RAMageddon. ” the worldwide shortage of memory chips fueled by the AI buildout.
President Jae Myung Lee put the timing front and center during a televised address Monday. “Semiconductors. physical AI. and AI data centers are the triple axis for South Korea’s next industrial era. ” he said. and argued that 2026 must become the year South Korea establishes itself as an “irreplaceable” industrial power.
Lee said existing chip facilities in Yongin and Pyeongtaek—on the semiconductor belt just south of Seoul—have “already reached their limits.” He urged companies to accelerate investment in the southwest, aiming to spread the benefits of AI growth beyond the nation’s capital.
“We must secure overwhelming production capacity in advance,” Lee said.
Not everyone buys the politics of that argument. Lee pushed back against media reports that the government had pressured companies into the investments. He reportedly said the decisions reflected companies’ own judgment. and that the government’s role is to invest its capabilities so companies can invest “without losses and with better prospects.”.
Samsung added its own layer to the plan on Monday. announcing it expects to invest 2. 655 trillion won (about $1.7 trillion) over the next decade. with 425 trillion won earmarked for the Honam region in the southwestern corner of the Korean peninsula. The company pointed to incentives around power. water. workforce. and living conditions as key reasons for choosing Gwangju—about 300 kilometers south of Seoul—for a new semiconductor fab. alongside an AI data center in Haenam at the southern tip of the peninsula.
The scale isn’t limited to Seoul. The announcement lands amid other global AI infrastructure spending. Alphabet, Amazon, Meta, and Microsoft are expected to collectively spend $650 billion on AI infrastructure this year alone, according to Reuters.
SK Group also laid out its own roadmap. announcing a 2. 100 trillion won (about $1.4 trillion) medium-to-long term investment plan: 1. 100 trillion won to expand semiconductor production capacity and 1. 000 trillion won for AI data centers nationwide. SK Hynix. the group’s core semiconductor affiliate. sits at the center of the chip expansion. while SK Telecom is set to lead construction of 15 gigawatts of AI data center capacity across the country.
The promise is clear, but the risk has always been part of the memory story. Deep tech like semiconductors and AI doesn’t move on political schedules or even customer demand timelines. Fabs take years to build. If demand falls by the time new capacity comes online. companies could be left with oversupply and crashing prices—right when they’re least able to absorb the hit.
So for now, the world’s AI chip supply chain—especially the part that’s been hungry for memory—will be watching South Korea closely. The question isn’t whether the investments are large. It’s whether they can arrive before the shortage that justified them starts to disappear.
