NVIDIA invested $3.5 billion in MediaTek convertible bonds while the companies expanded collaboration across custom data-center XPUs, future RTX and DGX Spark chips, and automotive platforms. MediaTek will use NVLink Fusion as a design foundation for customer accelerators connected to NVIDIA rack-scale systems.
Why it matters: The agreement gives hyperscalers another semi-custom accelerator route while extending NVIDIA's interconnect, memory, packaging, manufacturing, and rack architecture deeper into partner-designed silicon.
SK hynix held the groundbreaking for a more than $4 billion advanced-packaging and research facility in West Lafayette, Indiana. The company plans to complete the cleanroom in the second half of 2028 and begin next-generation high-bandwidth-memory packaging and volume production in the second half of 2029, using wafers produced in Korea.
Why it matters: The project creates a dated construction milestone for a first US HBM packaging base, but it also makes clear how far announced AI-memory capacity remains from qualified, shipped supply.
SpaceX and Tesla formally announced a $16.8 billion first phase for the planned Terafab chip complex in Texas; Grimes County, Intel involvement, and a possible $119 billion full buildout had been reported earlier.
Why it matters: The official first-phase figure advances a long-term custom-silicon plan, but does not create available fabrication, memory, packaging, or testing capacity.
The Commerce Department signed letters of intent with seven companies for co-packaged optics, 3D memory, advanced packaging, thermodynamic sampling and supply-chain verification. Proposed support includes up to $300M for GlobalFoundries and $245M for Kepler.
Why it matters: Scaling AI depends on memory bandwidth, interconnects, packaging and energy efficiency, so public investment is moving beyond accelerators into the complete compute system.
IonQ agreed to acquire semiconductor foundry SkyWater Technology in a cash-and-stock transaction valued at about 1.8 billion dollars. The companies said the combination would bring quantum design, fabrication, packaging, control systems, networking, and application software into one United States-based platform.
Why it matters: A leading quantum company moved to control more of its manufacturing stack, reflecting the strategic importance of fabrication capacity and supply-chain sovereignty.
