The soaring global demand for AI computing power has propelled Arm's total market value to surpass the US$300 billion milestone for the first time. On May 21, as the US stock market opened, Arm's stock price surged by 11%, reaching a record high of US$284.49, following a significant 15.05% increase in the previous trading session. SoftBank, the major shareholder, holds approximately 87% of Arm's shares and currently boasts a paper profit exceeding US$220 billion, with a return rate of 550%. Influenced by this, SoftBank's Japanese stock also soared nearly 20% today. The rise in Arm's stock price was fueled by the latest report from Bernstein, which gave Arm an 'Outperform' rating and set a target price of US$300. The report suggests that Arm will dominate the next era of computing, with its CPU market share expected to quadruple over the next four years and profits to increase fivefold by 2030. Arm's financial results for the most recent fiscal quarter showed a 49% year-on-year increase in net profit, reaching US$313 million, and a 20% increase in revenue, reaching US$1.49 billion.
