SK Hynix briefly overtook Samsung Electronics on June 22 to claim the top spot by common-share market capitalization on South Korea's KOSPI exchange, a milestone that reflects how high-bandwidth memory (HBM) has redefined the value of Korea's semiconductor industry.

The memory industry is entering a super cycle as prices keep soaring, with industry sources saying third-quarter 2026 contract price gains show no sign of slowing amid tight supply from upstream vendors. Overall increases could reach 30% to 40%, after second-quarter 2026 contract prices already climbed 40%. As market prices continue to stack higher in the second half, profits at the top three memory manufacturers are set to expand sharply, driving a surge in full-year memory business earnings.

AI-driven memory price spikes are presenting a challenge for Samsung's smartphone business, with rising component prices eroding the affordability of its budget phones. At the same time, Samsung is seeking to use its new AI features to encourage new device purchases as memory prices dampen smartphone sales globally.

Taiwan's memory chip designers are heading into a sharply stronger 2026 as rising memory prices and a wave of AI-driven demand push the industry away from consumer electronics and toward higher-value data center and AI applications.

Kioxia, one of the world's major NAND flash memory suppliers, is prioritizing long-term agreements (LTAs), BiCS migration, and domestic fab efficiency over aggressive capacity expansion, signaling a more disciplined approach to the AI storage cycle.

In an exclusive interview with The Wall Street Journal, Apple CEO Tim Cook made an unusually blunt admission. The company is preparing to raise product prices because memory and storage costs have surged to a point Apple can no longer absorb. He said Apple has spent the past stretch trying to shield customers from these cost increases, but the situation has become "unsustainable."

SK Hynix has eliminated degree requirements from its regular recruitment process for new employees, as the memory chip giant seeks to strengthen its lead in high-bandwidth memory (HBM) and secure talent for the fast-changing AI semiconductor market. Industry watchers said the move reflects a greater focus on practical creativity and execution in the AI era rather than formal academic credentials.

SK Group's combined market capitalization on the South Korean stock market surpassed KRW2,000 trillion (US$1.32 trillion) for the first time as of the June 16 close, driven by strength in AI memory demand and a high-profile visit by Nvidia's CEO that reinforced ties with SK Hynix and broader AI infrastructure plans. According to reports from SBS, YTN, ET News and Yonhap, the group's 19 listed subsidiaries reached a combined market value of KRW2,019.6 trillion, a 2.5% increase from the previous trading day.

Nvidia is expected to surpass Apple and Samsung Electronics' mobile division to become the world's top buyer of LPDDR, as AI servers and AI PCs pull low-power memory beyond smartphones, MoneyToday reported, citing electronics industry sources.

Semiconductor materials suppliers are moving to rebuild depleted inventories and recover sharply higher costs from Samsung Electronics, SK Hynix and other memory chip customers after the 106-day US-Iran war strained supply chains for precursors, specialty gases and other key chipmaking inputs.

Samsung Electronics has secured key technology for a 5nm-class magnetoresistive random-access memory cell, according to Korean financial daily Sedaily, moving ahead just four months after presenting what it described as the world's first 8nm-class MRAM at an international conference.

Apple is stepping up the AI capabilities of its Siri voice assistant, and analysts say memory chip demand will rise along with it, potentially benefiting Apple's suppliers such as Samsung Electronics and SK Hynix. The shift could drive both shipment growth and higher prices for mobile DRAM.

The semiconductor supply chain is facing another raw material shock — this time from tungsten hexafluoride, or WF6, a specialty gas used in chip manufacturing. Planned production adjustments or exits by some Japanese suppliers in the second half of 2026 have intensified concerns over tighter global supply, sending prices sharply higher and raising the risk of disruption into 2027.
