New York, Feb 9, 2026, 09:32 (EST) — Regular session
- Micron shares popped roughly 3% early Monday, reversing earlier premarket declines.
- Fresh headlines about Samsung’s upcoming HBM4 memory for Nvidia grabbed traders’ attention.
- Next up: Micron hits the circuit Feb. 11, with U.S. data releases also looming this week.
Micron Technology (MU.O) bounced roughly 3% higher to $394.69 in early Monday trading, reversing an earlier premarket dip as investors processed fresh chatter about rivalry heating up in the high-end memory chip space.
This is key: Micron’s turned into a high-conviction play on high-bandwidth memory, or HBM, the stacked memory chips powering AI processors. Supplies are tight, profits are fat. But if competitors look like they’re jumping ahead with new parts, that narrative can crack in a hurry.
Samsung Electronics is gearing up to start mass-producing HBM4 chips for Nvidia’s AI processors later this month, South Korea’s Yonhap News Agency reported, per Barron’s. Micron, for its part, won’t be scaling up HBM4 output until the second quarter of 2026, CEO Sanjay Mehrotra told analysts during its latest earnings call, Barron’s said. 1
Shares dropped over 3% before the market opened, echoing weakness in some chip stocks as last week’s tech rout reignited doubts about the payoff pace from big AI investments. “The size of the rebound … didn’t feel like the beginning of a sustainable reversal,” Swissquote Bank’s Ipek Ozkardeskaya wrote. Traders are now looking ahead to the delayed January U.S. nonfarm payrolls data due Wednesday, with January CPI set for Friday. 2
Big AI chip buyers are looking to diversify suppliers to sidestep bottlenecks, some analysts say. UBS’s Timothy Arcuri, in a note picked up by Barron’s, described AI accelerator vendors as “converging on a full three-supplier sourcing strategy.” 1
Micron’s immediate challenge: what it says, not what it builds. The chipmaker will present at Wolfe Research’s Auto, Auto Tech and Semiconductor Conference on Feb. 11, its investor calendar shows. 3
Yet the risks are clear enough. Should Samsung and SK Hynix secure a bigger chunk of HBM4 contracts ahead of time—or if Nvidia raises the bar on qualification—Micron might hit a wall on both pricing and market share, right when 2026 profit forecasts remain stubbornly high.
Right now, all eyes are on fresh updates about HBM4 qualification and how supply might shake out. Micron’s slated to speak Feb. 11, and that’s the next event traders have circled. 3
