Micron Technology delivered the strongest quarter in its history, the chipmaker said as it reported fiscal third-quarter results on June 25, 2026, with surging demand for AI memory driving record revenue and profit and a backlog of multi-year customer commitments unlike anything the memory industry has seen.
AI memory demand breaks records
Micron said it signed 16 take-or-pay Strategic Customer Agreements that lock in roughly $100 billion in minimum contracted revenue, alongside about $22 billion in upfront customer cash. The deals underscore how AI data-center operators are racing to secure scarce high-bandwidth memory (HBM) years in advance. Management said demand continues to outpace supply across HBM, DRAM and NAND, with constraints expected to persist well beyond 2026.
HBM4 ramp at the center
The growth is anchored by Micron's HBM4, its fourth-generation high-bandwidth memory for AI accelerators. HBM has become the most sought-after memory product as generative AI workloads demand ever more bandwidth, and the total addressable market is projected to grow roughly 40% annually toward about $100 billion by 2028. Micron's results land days after rival SK hynix shipped 12-layer HBM4E samples and weeks after Samsung advanced its own AI memory and foundry roadmap.
A tightening three-way race
SK hynix has led the HBM market with a share above 50%, followed by Micron and Samsung, but Micron's locked-in agreements signal it intends to close the gap as customers diversify supply. The memory upcycle is rippling across the broader AI hardware stack, from inference accelerators such as d-Matrix's Corsair platform to memory-centric acquisitions like AMD's purchase of Mext. With record results and an unprecedented contracted backlog, Micron has positioned itself as one of the clearest beneficiaries of the AI infrastructure buildout.
