NVIDIA invests $3.5B in MediaTek and opens NVLink Fusion to custom XPU designs
NVIDIA put $3.5 billion into MediaTek convertible bonds and will let MediaTek offer NVLink Fusion as a prevalidated design base for custom accelerators, alongside continued work on RTX Spark and DGX Spark PC chips and Dimensity Auto vehicle platforms. The substance is connectivity lock-in: hyperscalers and frontier labs building their own XPUs can now source the packaging, NVHBM memory, and rack-scale integration from NVIDIA's stack instead of engineering it, which keeps custom silicon inside NVIDIA's fabric rather than competing with it.

Rather than engineering and qualifying every element surrounding a custom XPU from the ground up, customers can focus resources on the differentiated compute that defines their platforms while relying on NVIDIA and MediaTek for the NVLink connectivity, memory architecture, packag
Why this matters
- → Custom silicon builders can now deploy accelerators on NVIDIA's fabric without reimplementing packaging, memor
- → Lock-in deepens: XPU designs tethered to NVLink ecosystem reduce switching costs for hyperscalers.
- → $3.5B investment signals NVIDIA's commitment to owning the full stack—from chip to rack.
