On June 24, ARM Holdings rose 4.6% in after-hours trading, trading at $371.30/share, with turnover of $24.66 million.

The rally was fueled by multiple catalysts. SoftBank CEO Masayoshi Son declared at the annual shareholder meeting that Arm will evolve from a chip designer to a chip provider, directly entering manufacturing. He predicted AI architecture is shifting toward CPU-centric design, asserting Arm has over 10x growth potential from its current valuation of approximately $391 billion.

Simultaneously, UBS raised its target price on ARM from $260 to $470 while maintaining a Buy rating. Bank of America also lifted its target from $335 to $460, citing AI-related spending visibility extending through 2028. Earlier, Bernstein identified Arm as the biggest beneficiary of the agentic AI era, raising its 2030 global server CPU market forecast from $137 billion to $223 billion.

Within the Semiconductors sector, Micron Technology rose 10.12%, Intel rose 2.18%, AMD rose 1.96%, Broadcom rose 1.16%, and NVIDIA rose 0.5%.
