UBS raised its price target on ARM Holdings to $245 from $175 while maintaining a Buy rating on the stock.

The firm conducted expert calls to assess the impact of agentic AI on the server CPU market. UBS projects the attach rate of CPUs to XPUs, including GPUs and TPUs, will grow approximately five times through 2030 compared to 2024 levels.

The largest portion of this growth is expected within XPU racks, particularly head nodes, the majority of which will be ARM-based. UBS also anticipates new demand for standalone CPU-only server racks, split roughly evenly between x86 and ARM architectures.

UBS estimates the server CPU market could expand to approximately $170 billion by 2030 from about $30 billion in 2025. The firm expects this growth to benefit ARM, Intel and AMD.

Intel rose again after soaring 13% in the previous trading day.
