- Micron shares were $14.82 higher at $746.81, while the SMH semiconductor ETF and QQQ were lower.
- Samsung suspended a planned 18-day strike by 48,000 union members after reaching a tentative pay deal.
- Micron’s operations chief told a J.P. Morgan conference on Wednesday that demand was still outstripping industry supply.
Micron Technology shares rose in Thursday trading, bucking a weaker tape as investors kept buying the memory-chip maker after Samsung Electronics reached a last-minute labor deal that reduced the threat of a fresh supply shock.
The stock was recently quoted at $746.81, up $14.82 on the session. The move stood out: the VanEck Semiconductor ETF, an exchange-traded fund that tracks a basket of chip stocks, and the tech-heavy Invesco QQQ Trust were both lower.
The reason this matters now is simple. Memory supply is tight, AI server demand is still absorbing capacity, and Micron sits in the small group of companies that can supply advanced DRAM, NAND and high-bandwidth memory. DRAM is short-term working memory used in servers and PCs; NAND is flash storage; high-bandwidth memory, or HBM, stacks memory close to processors so AI systems can move data faster.
Samsung, the world’s biggest DRAM maker, suspended an 18-day strike by about 48,000 union members after a government-mediated deal. Union members are due to vote on the agreement between May 22 and May 27, and the union leader has said he expects it to be ratified.
That keeps Samsung in production, but it also keeps investors focused on how scarce memory capacity has become. A Reuters explainer this week cited KB Securities analyst Jeff Kim as estimating that an 18-day strike could have disrupted global DRAM supply by 3% to 4% and NAND supply by 2% to 3%.
The competitive context is narrow: Samsung, SK Hynix and Micron dominate the discussion. Samsung’s deal was also read as a signal that the AI boom is spilling into labor costs, after SK Hynix had moved faster in supplying advanced AI memory to Nvidia.
Ryu Young-ho, a senior analyst at NH Investment & Securities, said investors were relieved the strike appeared to have been avoided, though he also flagged much higher labor costs. He said Samsung’s plan to pay special bonuses mostly in stock “avoids direct cash outflows” while helping support its share price. Reuters
Micron had its own fresh message for the market. Manish Bhatia, Micron’s executive vice president of global operations, told J.P. Morgan’s technology conference on Wednesday that the company’s “financial outlook has strengthened” and that demand continued to exceed both Micron’s and the industry’s ability to supply.

The company’s last reported numbers give that trade some backing. Micron said fiscal second-quarter revenue rose to $23.86 billion from $8.05 billion a year earlier, and it guided fiscal third-quarter revenue to $33.5 billion, plus or minus $750 million. Chief Executive Sanjay Mehrotra said memory had become “a strategic asset” for customers in the AI era. Micron Technology
Nvidia’s earnings kept the demand side in view, even though its own stock slipped. The AI chipmaker reported revenue of $81.62 billion, up 85%, and forecast about $91 billion for the current quarter. CEO Jensen Huang called the AI buildout the “largest infrastructure expansion in human history.” AP News
The broader market was less forgiving. Wall Street’s main indexes fell as oil prices and Treasury yields rose, with the Nasdaq Composite down 0.33% late Thursday morning and Nvidia lower despite its upbeat forecast.
But the Micron trade still has traps. Samsung’s labor deal faces a union vote, higher pay could alter cost discipline across the sector, and a reversal in memory pricing would hit the bullish case quickly. Rising yields are another risk for high-growth tech shares, since they make future earnings less valuable in today’s money.
For now, investors are treating Micron less like an old-cycle commodity chip stock and more like a scarce-capacity supplier to AI infrastructure. That is a powerful story while supply stays tight. It will be harder to defend if Samsung, SK Hynix or Micron add capacity faster than demand can absorb it.
