ARM-based servers accounted for over 45% of global data center revenue in Q1 2026, marking a tectonic shift away from x86 architecture. IDC reported the global server market hit a record $122.6 billion in revenue, up 30.4% year-over-year, with non-x86 platforms generating $58.7 billion (a 107.6% YoY surge) and representing 47.9% of the total market.
The ARM advance is driven by AI infrastructure. Systems with various accelerators—GPUs and custom ASICs/FPGAs—accounted for over 70% of Q1 revenue, with GPU-equipped servers producing $68.9 billion and other accelerated systems (including custom AI chips) reaching $17.7 billion, up 122% YoY. NVIDIA's NVL72 Blackwell and custom Arm-based offerings from hyperscalers (Google, AWS, Microsoft) dominate this segment.
While x86 servers by Intel and AMD remain dominant in unit volume (20 million processors per year), revenue share is collapsing: x86 revenue declined 2.9% to $63.9 billion, constrained by CPU/memory shortages. ARM-based systems—mostly NVIDIA's Grace CPUs and custom silicon—accounted for 95% of non-x86 revenue. NVIDIA is on track to ship 4 million ARM CPUs in 2026, with more custom ARM programs accelerating.
For architects: ARM's revenue dominance (not yet units) reflects the GPU-centric, hyperscaler-driven shift. Enterprise and sovereign AI projects favor branded vendors (Dell, Supermicro, HPE), which grew faster than ODM Direct. Expect x86 to stabilize at ~35–40% of revenue as branded enterprise AI adoption deepens and hyperscalers scale custom silicon.
