Micron Technology (MU) stock surged 18.36% on July 30, 2026, closing at $900 and adding another 3.05% in pre-market trading. The rally follows a sector-wide upswing driven by South Korea’s KOSPI posting its largest single-day gain in history, with SK Hynix and Samsung Electronics rising 24% and 20% respectively. Taiwan’s TAIEX gained over 8% led by TSMC and other AI chipmakers. Strong earnings reports from Microsoft, Amazon, and Apple also boosted sentiment. Amazon and Apple executives warned of rising memory chip costs due to high AI demand, leading investors to anticipate higher sales for Micron. The company recently announced a $250 billion investment plan to expand domestic production. Wall Street analysts predict the stock could trade beyond $1,300, though risks from the US-Iran conflict, high oil prices, and potential inflation remain.

The rally follows a sector-wide upswing. South Korea’s KOSPI saw its most significant single-day gain in history, with SK Hynix and Samsung Electronics leading the charge at 24% and 20% gains respectively. Taiwan’s TAIEX index gained more than 8%, led by TSMC and other AI chipmakers. This Asian market upswing likely crept into the US market.
Strong earnings reports from Microsoft, Amazon, and Apple also boosted investor sentiment. The companies reported higher-than-anticipated revenue. Amazon and Apple executives warned of rising memory chip costs due to high AI demand, leading investors to anticipate high sales for Micron.
Micron also recently revealed a $250 billion investment plan for the US to ramp up domestic production. Wall Street analysts are becoming increasingly bullish, with most major firms predicting the stock to trade beyond the $1,300 price level.
However, risks remain. The US-Iran conflict could threaten supply chains. Oil prices are still high, and July inflation could come in higher than expected, potentially leading to a price correction for Micron.
