Micron stock climbs as AI memory demand keeps prices tight

Micron Technology (ISIN US5951121038) stock gained after AI-infrastructure earnings from CoreWeave and Super Micro Computer helped reinforce demand for memory chips, while Micron itself reported $41.46 billion in fiscal third-quarter revenue and $25.11 in non-GAAP EPS. Shares closed at $911.29 on August 12, 2026, after a 4.92% move, and one market snapshot put the company at about $1.03 trillion in market value.

AI demand is the hook

Micron's latest quarter covered the period ended May 28, 2026, and the company said revenue jumped 345.8% year over year from $9.30 billion in the prior-year period. Gross margin also widened sharply, with one earnings recap putting the quarter at 84.9%, up about 10 percentage points from the prior quarter.

That backdrop matters because Micron's fiscal fourth-quarter guidance points to $50.0 billion in revenue, plus or minus $1.0 billion, with non-GAAP EPS at $31.00, plus or minus $1.00. The comparison is stark: Wall Street was looking for about $50.81 billion in revenue and $31.27 in EPS for the next report on September 22, 2026.

What the market is pricing

Micron's shares have also been trading near the top of the semiconductor tape, with one quote page showing a 52-week range of $113.46 to $1,255.00 and volume of 36.57 million shares on August 12, 2026. Another market snapshot showed the stock at $913.82 and market capitalization at $1.02 trillion as of August 13, 2026.

The bigger question for investors is whether memory pricing can stay this strong. A recent conference comment from Micron management said supply may stay constrained through 2027, and that timeline gives the current margin story more durability than a one-quarter spike.

Memory chips stay central

Micron's memory and storage products sit at the center of AI server buildouts, especially high-bandwidth memory for accelerators and data-center systems. That is the product story behind the numbers, and it is why revenue, margin, and guidance are carrying more weight than a simple one-day price move.

Micron stock levels

Micron stock closed at $911.29 on August 12, 2026, and one portal showed a market cap near $1.03 trillion on August 13, 2026. The next earnings date is September 22, 2026, and that report will be the next clear test of whether the current $50.0 billion revenue guide holds.
