Kioxia Holdings has gained 2,000% over the past year, nearly four times Japan’s next-best-performing stock. The chipmaker is down nearly 9% today, leaving investors torn between calling it a success or a bust.
Kioxia (285A) sits far ahead of the field on the Tokyo Stock Exchange. AIMECHATEC, the second-best yearly gainer, is up 540.30% over the same period.
Kioxia’s rally traces back to the AI buildout. Data centers scrambling for NAND flash memory, the storage chips used in phones and servers, pushed prices and profits sharply higher through 2025 and into this year. The stock surged more than 500% in 2025 alone, briefly making Kioxia Japan’s most valuable listed company by market cap.
That momentum cracked in late July. Kioxia forecast fiscal half-year operating income of ¥3.16 trillion ($19.7 billion). That figure implies a weaker-than-expected ¥1.89 trillion for the current quarter, after a ¥1.27 trillion prior quarter that already missed analyst estimates. Kioxia paired the outlook with a three-for-one stock split and an ¥800 billion buyback, aimed at broadening its shareholder base.
Shares had already retreated roughly 65% from their June peak of ¥112,700 by then. A broader AI-stock selloff pressured the sector, and Chinese NAND manufacturers ramped up capacity, threatening the pricing power behind Kioxia’s climb.
The latest 9% drop follows a stretch of sharp swings, not a steady decline. Kioxia shares gained more than 40% in a recent five-day stretch, then reversed sharply.
Analyst opinion reflects that split. Fourteen firms rate Kioxia a buy, while one recommends selling, and average price targets imply more than 100% upside. Daiwa, UBS, and Goldman Sachs reaffirmed buy ratings this week, while Bernstein kept its sell rating unchanged.
Revenue and profit still show strong year-over-year growth. The bigger question is timing. Is this a reset within a durable AI memory cycle, or the start of fading pricing power? Kioxia’s next earnings report should offer a clearer answer.

Meta has become the latest major AI company to disclose that one of its models hacked another company’s systems during testing, following similar incidents involving Anthropic and OpenAI. The model involved Meta’s Muse Spark 1.1, which launched in July, according to The Information, citing sources. The issue reportedly stemmed from a misconfiguration by Irregular, an artificial intelligence security testing and red-teaming firm, which inadvertently gave the model internet access during an evaluation. The model “exploited a security vulnerability in a third-party service, in a manner similar to previously reported instances with other companies,” Meta told Reuters in a statement. The incident is the latest case of an advanced AI agent becoming a cybersecurity risk in its own right, and also has raised questions about where the liability lies — the companies that develop the agents, or the ones that design the sandboxes meant to contain them.

All three incidents happened within or while interacting with the evaluation environment of Irregular, and involved a misconfiguration that left machines that Claude accessed with live internet access.Cointelegraph reached out to Meta and Irregular for comment.In July, AI agents developed by OpenAI broke out of their offline sandbox to hack Hugging Face in order to cheat on a security benchmark test in July. Charles Guillemet, chief technology officer of Ledger, said the latest incident was “marketing theatre.”“Having a model ‘go rogue’ has become the latest AI PR stunt,” he said on Wednesday. “If your model isn’t escaping sandboxes, ‘hacking’ companies, or pulling off some headline-grabbing exploit, apparently you’re falling behind… The industry doesn’t need bigger stunts, it needs more trust.”Magazine: Do the Coldcard attacks mean all hardware wallets are now insecure?
