AI Fuels Chip Market
Micron and Qualcomm forecasts ignite $400 billion AI chip stock rally, boosting market value.
Chipmakers surged Wednesday night, adding more than $400 billion in market value in a single after-hours session, according to Reuters. The rally was sparked by blowout earnings from Micron Technology and a bold investor-day presentation from Qualcomm, erasing nearly all of the losses from a brutal sell-off the day before.
Micron shares jumped roughly 15% after the company crushed Wall Street expectations for its fiscal third quarter of 2026. Qualcomm rose 11% after it unveiled plans to compete directly with Nvidia in the AI data center market. Together, the two companies helped drag the entire Philadelphia Semiconductor Index higher, according to Yahoo Finance.
Micron Posts Record Results and Raises Guidance
Micron reported fiscal Q3 2026 revenue of $41.46 billion — far above the $35.85 billion Wall Street expected. Earnings per share came in at $25.11, beating forecasts of $20.78. Year-over-year revenue growth hit 346%, according to Quartz. CEO Sanjay Mehrotra called the results a sign of "the strategic value of memory in the AI era."
Even more striking was the company's outlook. Micron guided for roughly $50 billion in revenue next quarter — nearly five times what it reported a year ago. The company said its entire 2026 supply of High Bandwidth Memory (HBM) — the type of fast memory that AI chips need most — is already sold out under fixed contracts, according to MarketScreener.
Qualcomm Declares War on Nvidia's Data Center Turf
Qualcomm used its 2026 Investor Day on Wednesday to announce a major shift away from smartphones. The company unveiled its Dragonfly C1000 AI processor, aimed at large data centers. Meta and Microsoft were named as early customers. CEO Cristiano Amon said Qualcomm is "evolving into a platform company," according to MarketScreener.
Qualcomm's data center chief Tony Pialis introduced new "High Bandwidth Compute" chips that he said use cheaper memory than Nvidia's chips, giving them a cost advantage. The company set a target of $15 billion in data center sales by 2029 and $40 billion in total non-smartphone revenue — double its previous goals.
Tuesday's Brutal Sell-Off Made the Rebound More Dramatic
The rally came just one day after a sharp global chip stock crash. South Korea's Kospi index dropped nearly 10% on Tuesday as foreign investors dumped semiconductor shares, tripping automatic trading halts. In the US, Micron fell 13.2% and Qualcomm dropped 8.25% in that session alone, according to Yahoo Finance.
Analysts at Rosenblatt Securities had warned ahead of Micron's report that demand was "strong enough to absorb higher pricing without meaningful demand destruction." That call proved right. Wednesday's after-hours session recovered nearly all of Tuesday's losses in just a few hours.
Bulls and Bears Still Disagree on What Comes Next
UBS and Bank of America raised their price targets for Micron to between $1,500 and $1,625 per share. They argued the memory boom is still in its early stages and that locked-in supply contracts give Micron unusually stable revenue, according to Yahoo Finance.
But not everyone is convinced the danger has passed. Bank of America also warned that "sharp declines and rapid recoveries are typical characteristics of bubble formation." Economist Mohamed El-Erian praised the rally as a sign of US economic strength but told investors to expect "more market volatility" ahead as the AI spending boom continues.
