SK Hynix and Micron top $1 trillion market value as AI memory-chip demand lifts shares
The Facts
- Micron and SK Hynix each surpassed a $1 trillion market capitalization for the first time, with Micron reaching the mark on Tuesday and SK Hynix on Wednesday.
- SK Hynix shares rose about 9.3% on Wednesday, lifting its market value above $1 trillion.
- Micron shares surged roughly 18% to 19% on Tuesday after UBS sharply raised its price target for the company.
- Multiple reports attribute the rise in both companies’ valuations to strong demand for AI-related memory chips, including high-bandwidth memory used in AI servers and accelerators.
- SK Hynix has become a key supplier to Nvidia, linking its rally to the broader AI hardware supply chain.
- Samsung Electronics had already crossed the $1 trillion market-cap threshold earlier in May, meaning the three major memory-chip makers are now above that level.
- SK Hynix shares have more than tripled this year, reflecting how strongly investors have revalued memory-chip makers tied to AI demand.
- The rally highlights how the AI buildout is affecting not only chip designers but also memory-chip manufacturers that supply data centers and AI systems.
How left and right are reading this
- Both agree
- AI demand is no longer enriching only chip designers; it is repricing the memory makers that supply servers, accelerators, and data centers, pushing all three major memory-chip companies above the $1 trillion threshold.
- They split on
- Less a disagreement than a question of emphasis: extraordinary value concentrating across core AI infrastructure, versus a market verdict that suppliers meeting real demand are being rewarded across the hardware chain.
