New York, Feb 9, 2026, 09:32 (EST) — Regular session
- Micron shares jumped about 3% out of the gate Monday, erasing losses from earlier in premarket trading.
- Samsung’s next-gen HBM4 memory for Nvidia landed in the headlines, snapping traders to attention.
- Micron steps into the spotlight Feb. 11. U.S. data drops are coming up later this week, too.
Micron Technology (MU.O) rebounded about 3% to $394.69 in early trading Monday, clawing back from an earlier premarket slide after fresh talk circulated about intensifying competition in the high-end memory chip market.
Here’s the crux: Micron’s now a go-to bet for high-bandwidth memory—the stacked chips behind AI processors. There’s not enough to go around, margins are juicy. Still, if rivals suddenly roll out newer components, that story could unravel fast.
Samsung Electronics plans to kick off mass production of HBM4 chips for Nvidia’s AI processors before the month is out, according to South Korea’s Yonhap News Agency, as cited by Barron’s. Micron isn’t rushing in—CEO Sanjay Mehrotra told analysts on its recent earnings call that HBM4 won’t be ramping up there until the second quarter of 2026, Barron’s noted.
Shares tumbled more than 3% ahead of the bell, with chip names sliding as last week’s tech rout cast fresh doubt on how quickly AI spending will pay off. “The size of the rebound … didn’t feel like the beginning of a sustainable reversal,” said Ipek Ozkardeskaya at Swissquote Bank. Next up, traders are eyeing the delayed January U.S. nonfarm payrolls numbers, which land Wednesday, and January’s CPI on Friday. Reuters
Major buyers of AI chips are starting to widen their supplier base, aiming to avoid supply snarls, according to some analysts. UBS’s Timothy Arcuri, cited in Barron’s, wrote that AI accelerator makers are now “converging on a full three-supplier sourcing strategy.” Barron’s
It’s not production, but messaging, that’s front and center for Micron right now. The chipmaker is set to speak at Wolfe Research’s Auto, Auto Tech and Semiconductor Conference on Feb. 11, according to its investor calendar.
Still, the risks stand out. If Samsung and SK Hynix lock in more HBM4 deals early, or Nvidia tightens up its qualification standards, Micron could run into limits on both price and share—just when those lofty 2026 profit targets are hanging overhead.
Traders are watching for new details on HBM4 qualification and possible shifts in supply. Micron is up next, scheduled to speak Feb. 11—the date everyone’s tracking.
