HBM4 Sold Out Through 2026, TSMC Alliance and $100B Market Target Reshape Micron’s Outlook Ahead of Q3 Report

Micron’s HBM capacity for 2026 is fully committed, meeting only 50–65% of client demand. The stock hits €930.40 as AI memory scarcity reshapes the industry.

Micron Technology has entered a new phase where HBM supply constraints are so acute that every gigabyte of fourth-generation high-bandwidth memory is already committed for the entire 2026 calendar year – and the company can only satisfy between half and two-thirds of its major clients’ medium-term demand. That scarcity, combined with a landmark partnership with TSMC for its next-generation HBM4E chips, has driven the stock to a fresh 52-week high of €930.40, up 1.77% on the day and 245.87% year-to-date. Over the past month alone, the shares have surged 88.76% as the market reframes Micron from a cyclical memory play into a structural bottleneck in the AI infrastructure supply chain.

The shift in narrative gained further momentum at industry presentations in early June, where Micron updated its total addressable market forecast for HBM to $100 billion by 2028 – two years ahead of previous expectations. The acceleration stems from a fundamental change in AI system design: memory bandwidth, rather than raw compute, is increasingly the performance limiter in large-scale inference and training workloads. Micron’s sixth-generation HBM4, already in mass production with 36 GB 12-layer stacks, is purpose-built for NVIDIA’s next-generation Vera Rubin AI platform, cementing the company’s role in the hyperscaler hardware stack.

To maintain that edge, Micron is now developing HBM4E – a generational leap that is ramping at twice the speed of HBM3E. For the first time, the memory maker is outsourcing the base die production to TSMC, using the foundry’s advanced 1-gamma (6th-gen 10 nm) process with EUV lithography. This break from in-house manufacturing signals a drive for maximum product quality as AI workloads transition from training to increasingly compute-intensive inference applications.

Raymond James analyst Melissa Fairbanks, after touring memory suppliers in South Korea and Taiwan, more than doubled her price target from $530 to $1,100, maintaining an “Outperform” rating. She sees the current upcycle diverging from previous boom-bust patterns due to the structural demand from AI. On Wall Street, 26 analysts rate Micron a buy and three a hold, though the average price target of $831.73 suggests the stock has already priced in a significant share of optimism. JPMorgan echoes the view, highlighting that the tightest links in the AI supply chain – HBM, optical networking, and cooling systems – are commanding increasing investor attention.

Those supply constraints are backed by hard numbers. CEO Sanjay Mehrotra has confirmed that Micron’s entire HBM4 capacity for 2026 is pre-sold, and even so, the company can only serve 50% to 65% of the mid-term demand from key customers. Meanwhile, TrendForce forecasts that the nine largest cloud providers will boost capital expenditure by 79% this year, and Counterpoint Research projects HBM demand for custom AI processors to grow 35-fold between 2024 and 2028. The combination of rising prices and full order books is translating into exceptional quarterly results.

All eyes now turn to the third-quarter earnings report scheduled for June 24, 2026. Management guided for fiscal full-year revenue of around $33.5 billion with adjusted earnings per share near $19.15. Analysts, however, are projecting third-quarter revenue of roughly $33.8 billion, which would represent a 263% surge from the prior-year period, supported by margin-rich HBM contracts and the ongoing transition to DDR5 and PCIe Gen6 memory solutions. The consensus full-year EPS estimate stands at $58.87.

The stakes are high. After such a dramatic rally, the market will scrutinize whether Micron can convert its production bottlenecks into sustained pricing power and widening margins. The upcoming report will serve as the reality check for a stock that now trades well above the average analyst target – but also one that continues to benefit from a structural shift that shows no signs of abating.
