Microsoft Locks Down SK Hynix HBM3e Supply for Maia 200 AI Chip

Microsoft recently announced the Maia 200 chip, signaling a deeper push into custom AI hardware. New reporting reveals how Microsoft plans to secure the memory backbone for its next-generation accelerators.

Exclusive HBM3e supply deal with SK Hynix

According to Bloomberg, Microsoft signed an exclusive agreement with SK Hynix to supply high-bandwidth memory for the Maia 200 AI accelerator. SK Hynix will provide all HBM3e memory modules used in Microsoft’s new chip lineup.

Each Maia 200 processor integrates six HBM3e memory modules and focuses on large-scale AI training and inference inside Microsoft data centers. This configuration supports extreme memory bandwidth demands required by modern AI models.

SK Hynix controls more than 90% of the global HBM3e market, giving it a commanding role in AI-focused memory supply. This dominance positions the company as a critical partner for hyperscalers building custom AI accelerators.

The announcement immediately lifted SK Hynix shares by around 8% on the Korean Stock Exchange. The surge pushed the company’s market valuation close to $400 billion, reflecting investor confidence in AI-driven growth.

Memory manufacturers now prioritize enterprise and data center production over consumer hardware. SK Hynix has fully shut down its consumer RAM facilities to focus on AI infrastructure, increasing pressure across the memory market and driving price hikes even for DDR4.

Exclusive supply deals between major tech companies boost enterprise profits while raising costs for consumers. Analysts also expect continued shortages in high-end GPUs from NVIDIA as AI infrastructure demand accelerates.

Microsoft recently reported a 16.7% revenue increase, and the Maia 200 initiative reinforces its position as a leading force in AI technology and infrastructure.
