The artificial intelligence (AI) boom has turned memory chips into one of the hottest corners of the semiconductor market. As tech giants continue pouring billions into AI data centers, demand for high-bandwidth memory (HBM) and NAND storage has pushed memory prices higher, lifting companies across the industry. Investors have largely believed that this spending wave still has plenty of room to run, helping memory stocks command rich valuations and raising expectations for strong earnings.
But every cycle eventually faces questions about how long the momentum can last. That uncertainty returned this week after Japanese memory giant Kioxia (KXIAY) delivered a weaker-than-expected outlook for the coming fiscal half-year. The guidance suggested that the rapid rise in memory prices could begin to cool, while fresh comments from another major Japanese supplier, Murata Manufacturing, also hinted that AI infrastructure spending may not remain at today’s breakneck pace forever.
