Micron reported third-quarter revenue of $41.45 billion, roughly four times the same quarter a year ago, as the AI-driven memory chip shortage pushed prices higher across the industry. Profit at the Idaho-based memory maker swung from $1.88 billion a year ago to $28.2 billion. Shares jumped more than 13% after the Wednesday earnings release and closed at $1,048.51 on June 24, 2026.
The company also guided fourth-quarter revenue to between $49 billion and $51 billion, signaling that management expects the supply squeeze to extend through the back half of the year. Micron's market cap now sits at $1.2 trillion, a remarkable repricing for a company whose stock traded around $83 in early 2024 with a market cap closer to $91 billion.
The backdrop is a memory shortage that some forecasters expect to persist through 2027. AI training and inference workloads consume high-bandwidth memory at rates that the existing fab footprint cannot match, and capacity additions take years. Micron, as the largest US computer-memory chip maker, sits in a structurally favored position relative to the broader chip supply chain.
Key facts
- 01Micron Q3 revenue hit $41.45 billion, roughly 4x the year-ago quarter.
- 02Q3 profit surged from $1.88 billion to $28.2 billion year-over-year.
- 03Shares rose more than 13% post-earnings and closed at $1,048.51, up from around $83 in early 2024.
- 04Micron guided Q4 revenue to $49 billion to $51 billion.
- 05Micron signed a memory and storage supply deal with Anthropic and joined its Series H round.
That position is starting to show up in customer deals. Micron disclosed this week that it signed an agreement to supply Anthropic with memory and storage chips, locking in one of the most compute-hungry AI labs as a named customer. Micron also participated in Anthropic's Series H funding round, though it did not disclose the size of the investment.
The Anthropic tie-up is notable on two counts. It pairs a long-dated supply contract with an equity stake, the kind of structure Nvidia has used to entrench itself with frontier labs. And it puts Micron directly inside the capital stack of a lab whose Claude models are now embedded in enterprise products including a Slack-native deployment Anthropic shipped this month.
The flip side of Micron's windfall is what customers further down the chain are paying. Apple CEO Tim Cook warned just a week ago that price increases for the company's products are unavoidable, a rare on-the-record acknowledgment from Apple that component costs are no longer absorbable inside existing margins. Memory is a meaningful share of the bill of materials for phones, laptops, and servers, and Cook's comment frames how the squeeze is moving from data center procurement into consumer prices.
Memory pricing power has historically been the most cyclical line in semiconductors. DRAM and NAND prices have collapsed in every prior cycle once supply caught up, and Micron's stock has been punished accordingly. The current cycle is different in one specific respect: the marginal buyer is an AI lab building multi-gigawatt training clusters, not a PC OEM managing inventory, and that buyer is willing to sign multi-year supply agreements at posted prices.
Still, the forecast through 2027 is a forecast, not a contract. If Samsung and SK Hynix bring new HBM capacity online faster than expected, or if frontier labs slow capex growth in response to their own funding constraints, the spot market could loosen sharply. SK Hynix's planned $29 billion Nasdaq ADR listing, which we covered earlier this month, is itself a signal that Micron's rivals are racing to fund expansion.
Micron's quarter is the clearest read yet on how the AI capex cycle is redistributing profit pools inside the semiconductor stack. Nvidia captures the accelerator margin, TSMC captures the foundry margin, and memory suppliers, long treated as a commodity tier, are now capturing a structural share of the AI bill. For Micron specifically, the question for the next four quarters is whether the Anthropic-style anchor deals can convert this cycle's windfall into something more durable than the last one. The Series H stake suggests management is trying.
