Kioxia (KIOXIA) rose 11.72% on August 4, 2026 — Bezos-backed AI startup deal lifts memory demand hopes.

The AI memory sector surged on broad tech momentum, with Kioxia (a leading NAND supplier) rising 11.7% in tandem with memory peers including SanDisk and Western Digital.

Kioxia's flash memory production benefits from sector-wide confidence in NAND supply-demand rebalancing — as the narrative shifts from oversupply risk to constrained capacity serving AI infrastructure, the entire memory…

The AI Memory theme rests on the thesis that HBM and DRAM tightness, plus renewed NAND discipline, will sustain pricing power; Kioxia's move reflects confidence that its production capacity and cost curve position it to…

Competitive pressure from Samsung or SK Hynix, or any sign of faster-than-expected new NAND capacity coming online, could reverse the pricing tailwind and pressure Kioxia's valuation.
