Nexthop AI's $500M raise at a $4.2B valuation (meeting cross.§D) signals a structural shift toward solving the networking bottleneck in hyperscale AI data centers (cross.§A).
Nexthop AI raised $500M in Series B funding at $4.2B valuation, led by Lightspeed Venture Partners with Andreessen Horowitz and Altimeter Capital participating. Founded by former Arista COO Anshul Sadana, the company develops high-performance networking switches for hyperscale AI data centers, including the industry's lowest power 51.2 Tbps switch and 102.4 Tbps air-cooled systems. This funding highlights how AI networking has become the new battleground as GPU investments face network bottlenecks - IDC projects global CSP capex to exceed $710B in 2026. With Eridu also emerging from stealth with $200M+ for high-radix switching technology, investors are betting that solving the network wall could save billions in wasted AI infrastructure spending.
