CSOP SK Hynix Daily 2x Leveraged Product surged another 12% after a 14% rally in prior trading session as local media said SK Hynix is the sole supplier of advanced memory for Microsoft Corp.’s new artificial intelligence chip.

CSOP Samsung Electronics Daily 2x Leveraged Product rose about 3%.

Each of the Maia 200 accelerators unveiled by Microsoft on Monday will use six units of SK Hynix’s HBM3E, Maeil Business Newspaper reported, citing chip industry and brokerage sources. SK Hynix is unable to confirm or disclose any customer-related information, a company spokesperson said in a text message.

The firm’s shares have surged tenfold on the Korea Exchange in around three years, riding investor enthusiasm for AI thanks to its early supply deal with Nvidia Corp. Pricing of legacy memory chips has started to improve as well, boosting the outlook for SK Hynix ahead of its results due Thursday.

Another positive tailwind came as Citigroup Inc. hiked its price target for SK Hynix by 56% to a street-high 1,400,000 won. They maintained their buy rating and opened a 30-day upside catalyst watch on the stock.

“The memory market is shifting toward semi-customization, with memory customers required to sign a contract a year prior to actual product delivery,” analyst Peter Lee wrote in a note Monday. “In 2026, we foresee global DRAM/NAND pricing growth to be significantly better than expected.”
