SK Hynix 54 Trillion Won CapEx Locked In; Nvidia Rubin Ultra Downgrading HBM Stack Amid Structural Supply Crunch
SK Hynix has formally committed 54 trillion won (~$39B USD) to new fabs at Yongin Y2 and Cheongju M17, with first meaningful HBM production not expected until 2027–2029 after 12–18 month yield ramp periods — offering no near-term supply relief. Concurrently, Nvidia is actively testing at least three downgraded HBM configurations for its next-generation Rubin Ultra GPU — including a reduction from the planned 16-stack HBM4E to 12-stack and potentially 8-stack HBM4/HBM4E variants — a direct product-specification response to confirmed HBM supply constraints, with AMD's MI400 reportedly following a parallel dual-stack strategy.

China Eyes Export Controls on AI Chips & Models; AMD Helios Rack Enters Market with Azure Deal
China's Ministry of Commerce is actively consulting with domestic AI firms on tighter export controls covering AI model weights, chip designs, and potential restrictions on overseas foundries—including TSMC and Qualcomm—from producing advanced semiconductors based on Chinese IP, per a Financial Times report cited by Reuters. Simultaneously, AMD has formally launched its Helios rack-scale AI system powered by MI455X GPUs, with Microsoft Azure confirmed as a new deployment customer for H2 2026, introducing a credible rack-level competitive alternative to Nvidia's CoWoS-packaged accelerator dominance.
