Memory shortages remain severe as HBM consumes DRAM capacity, preserving supplier pricing power despite already extraordinary price increases. SK hynix expects memory shortages through 2030, while its new Indiana HBM4E capacity will not arrive until 2029. Micron Technology, Inc. expects FY2027 CapEx above the mid-$40 billion range, yet meaningful greenfield bit supply begins around calendar 2028.

SK Hynix has positioned itself at the center of the AI supply ecosystem.

SK Hynix stock rebounded on Tuesday as South Korean chip stocks recovered from early losses, but a shift in the next generation of high-bandwidth memory is creating a new question for investors. The stock rose about 1.9% to 1.706 million won by 10:30 a.m.

China's memory-chip ambitions are moving into the heart of the artificial-intelligence supply chain. CXMT has begun producing small quantities of HBM3E, an advanced high-bandwidth memory used in AI chipsets, according to Reuters.

The AI boom is turning memory from a cyclical semiconductor component into critical infrastructure. Manufacturers can add factories, but advanced high-bandwidth memory (HBM) takes years to qualify, ramp, and produce at scale.
