RISC-V in the AI Data Center: How NVLink Fusion Broke the x86 Duopoly in 2026
In 2026, RISC-V stopped being a hobbyist curiosity and entered the AI data center. SiFive integrated NVIDIA NVLink Fusion into its RISC-V CPUs, raised $400M at a $3.65B valuation, and hyperscalers began designing custom silicon on an open ISA. Here is what the RISC-V data center moment means for infrastructure builders, why NVLink Fusion is the enabler, and what breaks next.
