Samsung Electronics and SK Hynix are planning large investments in chip production capacity to address surging demand for memory chips linked to global AI spending. Multiple reports say the companies are expanding manufacturing through new and upgraded facilities, with investment levels described across outlets as hundreds of billions of dollars. The Financial Times and Wall Street Journal both report that the firms plan very large expansion efforts supported by South Korean government involvement, framing the move as necessary because existing capacity and prior investment plans are not expected to be sufficient for forecast demand amid a broader memory chip shortage. Quartz adds that each company is preparing to build two new fabrication plants in South Korea’s southwest, aligning the expansion with capacity constraints driven by AI-related demand. TechNode reports parallel moves in China, citing South Korean media that Samsung and SK Hynix are also making large-scale investments at their factories in China to upgrade process technology and increase production capacity. Taken together, the coverage indicates coordinated capacity additions in both South Korea and China to scale memory output and improve manufacturing capability.
