Micron Quadruples Revenue and Asia's Stock Markets Surge

Micron sold $41.46 billion of memory chips in three months. In the same quarter a year earlier it took in $9.30 billion. That single comparison, buried in an earnings release on Wednesday, did more to settle this week's nervous markets than any central banker could.

Asian equities surged on Thursday after the results from Micron, and a bullish forecast from Qualcomm, eased fears that the artificial-intelligence boom propping up global stocks had run too far ahead of reality. Japan's Nikkei rose more than 2% and South Korea's Kospi gained 5.5%, according to Reuters. It was a sharp reversal from the chip sell-off that routed the same markets earlier this week, when the Kospi sank almost 10% in a single session.

The detail that mattered was not the headline revenue but what stands behind it. Micron said it had signed 16 multi-year supply agreements locking in roughly $100 billion of minimum contracted revenue and $22 billion of upfront customer cash. Non-GAAP gross margin hit a company-record 84.9%; earnings came to $25.11 a share. The company guided to about $50 billion in revenue for the current quarter. Shares jumped about 15% in extended trading, extending a 2026 gain CNBC put at 244% that has already carried Micron past a $1 trillion market value.

Translate that into the things people actually buy, and the picture is less comforting. Memory is the commodity inside every laptop, phone and data-center server, and a shortage this severe pushes prices up across all of them. Micron has been telling customers for months it can fill only part of their orders, and chief executive Sanjay Mehrotra was unusually candid on the call about how long that lasts.

"Micron currently does not have line of sight as to when memory supply will be able to catch up with increasing demand."

For South Korea the boom has been a national windfall. SK Hynix and Samsung Electronics, the two firms that dominate high-bandwidth memory alongside Micron, have powered the Kospi up roughly 112% this year, the best performance of any major index in the world, Reuters reported. The same dynamic that lifts those share prices is what makes a new graphics card or a server upgrade more expensive for everyone downstream.

None of this resolves the argument that started the week's wobble: whether AI valuations have simply climbed too high. A backlog of signed contracts is a sturdier thing to own than a forecast, and that is why Micron's numbers calmed nerves where the run-up to these results had only raised them. But take-or-pay deals stretch years into the future and assume the AI build-out keeps its appetite. If that appetite cools before the new factories come online, the same orders that look like a fortress today become a liability. For now, the chips are spoken for, the supply is short, and the market has decided to enjoy it.
