Samsung Electronics and SK Hynix are expanding memory-chip production capacity to address strong demand driven by global AI investment and ongoing memory supply constraints. Multiple reports say the companies plan major, multi-year capital spending on new fabrication and related facilities. The Financial Times and Wall Street Journal report that Samsung and SK Hynix plan a combined investment figure in the hundreds of billions of dollars, with Financial Times citing a total around $590 billion and the Wall Street Journal citing about $520 billion for new chip plants in South Korea.

In parallel, TechNode reports that both companies are also making large-scale facility investments in their factories in China, focused on upgrading process technology and increasing production capacity. Seeking Alpha and Yahoo Finance focus on SK Hynix’s portion of investment, reporting a plan of about $64 billion for memory-chip and packaging facilities.
