Kioxia’s stratospheric climb illustrates the tech industry’s booming demand for memory as hyperscalers rush to build out AI infrastructure. Chips like Kioxia’s are essential for AI training and data centres. This year, major tech firms warned of a memory supply crunch amid soaring demand, with analysts forecasting a jump in prices.
(Dec 30): Artificial intelligence’s insatiable appetite for data storage has delivered Japanese memory chipmaker Kioxia Holdings Corp world-beating stock gains this year, a sign that the AI boom is alive and well despite recent market jitters.
Kioxia’s shares have risen around 540% year-to-date, outperforming all other members of the MSCI World Index and making it the top stock in Japan’s Topix benchmark for 2025. The NAND flash memory maker, which only debuted on the Tokyo Stock Exchange last December, counts Apple Inc and Microsoft Corp among its clients and is now worth about ¥5.7 trillion.
