# Interconnect Becomes the Accelerator Moat

Competition in AI silicon keeps shifting from chip performance to who controls the rack-scale interconnect and chassis standard, so specialized challengers increasingly join the dominant platform rather than build alternatives to it.

- [confirms] d-Matrix Will Plug Its Inference Chips Into NVIDIA Racks Through NVLink Fusion (2026-09-11): d-Matrix will attach up to 144 of its Raptor inference accelerators to a single NVLink Fusion domain inside NVIDIA racks, with rack-integrated systems expected in Q4 2027. A challenger silicon vendor choosing to join NVIDIA's interconnect rather than compete with a rack standard of its own is the exact consolidation dynamic the thesis tracks.
