Korea’s $518B chip plan raises questions for Micron

South Korea announced that Samsung Electronics and SK Hynix will invest 800 trillion won, about $518 billion, to build new semiconductor fabrication sites focused on DRAM and high-bandwidth memory (HBM). The plan is part of President Lee Jae Myung’s industrial strategy to expand manufacturing beyond the Seoul area and increase the country’s AI memory capacity.

Samsung and SK Hynix plan to add large-scale DRAM and HBM production. HBM is used alongside AI processors in data centers and other server applications. Samsung seeks to boost its memory business, while SK Hynix aims to protect the lead it gained from heavy HBM demand linked to AI workloads.

Micron Technology has benefited from tight memory markets. The company reported strong quarterly results driven by AI workloads, HBM shortages and firm pricing. Micron has secured about $22 billion in customer commitments across data center, consumer and automotive segments. Those agreements include take-or-pay terms, cash deposits and pricing floors that lock in supply and pricing arrangements in advance.

Market participants and industry analysts say AI demand has outpaced available memory supply, supporting higher prices and creating urgency among customers to secure inventory. Daniel Newman, CEO of Futurum Group, called the scale of the AI buildout underestimated and cautioned that memory may continue to command “premium pricing” while supply remains constrained.

Analysts note that building new fabs and qualifying next-generation HBM are complex and time-consuming processes. New production capacity is expected to take several years to come online, and HBM qualification involves technical hurdles that can delay volume shipments. KB Securities and Jefferies analysts pointed out that if Samsung successfully qualifies next-generation HBM, supplier dynamics could shift toward Samsung and SK Hynix because of Samsung’s large manufacturing footprint.

Industry specialists add that customers do not switch memory suppliers quickly and that existing long-term contracts and supplier relationships will limit immediate effects on Micron’s sales. Those contracts are intended to provide revenue visibility for suppliers while also ensuring customers access to scarce chips for AI deployments.

Analysts say the South Korean investment does not present an immediate threat to Micron because new fabs will not resolve current shortages overnight. They also caution that investor expectations could change: if the market becomes convinced a credible surge of DRAM and HBM capacity will arrive after 2027, investors may begin to factor weaker memory pricing into valuations before the new capacity is actually operational.
