Overview
- Kioxia hit an intraday market value above ¥45 trillion on June 3, briefly overtaking Toyota before the stock closed lower and left Toyota technically ahead at session end.
- The stock has surged since a December 2024 IPO, rising more than 3,500% overall and over 660% year-to-date through early June 2026.
- Kioxia reported record quarterly revenue of ¥596.8 billion for the March 2026 period and gave June-quarter operating profit guidance of ¥1.3 trillion.
- Market moves earlier in June also put SoftBank briefly at the top of Japan’s market-cap rankings, showing investor rotation into AI and chip-related names.
- Key near-term risks include concentrated ownership by Bain Capital that could pressure the share price if large stakes are sold and capacity expansion by Samsung and SK Hynix that could loosen NAND pricing.
