Nvidia backs AI networking switch silicon startup Upscale in $190M raise - SDxCentral

NVIDIA has led a $190 million funding round in Upscale AI, a startup developing AI-focused networking switch silicon. This brings Upscale’s total funding to $500 million and its valuation to $2 billio... Read original →

NVIDIA’s lead investment in Upscale AI is a strategic move to dominate the AI fabric layer, where communication bottlenecks now limit model scaling. If Upscale’s SkyHammer silicon—built on 3nm EUV and natively compliant with ESUN/SONiC—delivers, it will disrupt legacy switch vendors like Juniper and even pressure NVIDIA’s own InfiniBand roadmap. Geopolitically, reliance on advanced nodes concentrated in Taiwan, China exposes Upscale to U.S. export controls, potentially inflating supply chain risk premiums by over 30%. Intel and Marvell will likely counter with integrated DPU-switch architectures, while startups like Auradine may target edge-AI niches. Within 18 months, purpose-built AI fabrics will shift from optional to mandatory in large-scale training clusters, catalyzing a $10B+ market for specialized switch silicon and forcing hyperscalers to redesign datacenter topologies. This isn’t just funding a startup—it’s NVIDIA scripting the next infrastructure standard.
