ARM's Market Value Surpasses $300 Billion; Masayoshi Son and SoftBank Have Profited Over $220 Billion in Recent Years

On May 21, driven by a surge in global AI computing power demand, chip architecture giant ARM saw its stock price soar over 10% during trading, marking its total market value surpassing the $300 billion threshold for the first time (reaching $300.9 billion). This historic milestone signifies that major shareholder SoftBank Group and founder Masayoshi Son have entered a phase of unprecedented returns in their investment careers, referred to as a 'super myth.' According to public data, SoftBank Group currently holds approximately 87% of ARM's shares. Based on an estimated total cost of around $40 billion from the '2016 privatization acquisition' and 'forced buyback before the 2023 IPO,' this investment has generated over $220 billion in profit in just a few years (approximately 1.6 trillion yuan), with an astonishing return rate of 550%.
