  "account": "The wealthiest individuals in Japan and South Korea suffered significant declines in wealth on a single day, according to Forbes real-time data. Japan's richest man, Son, CEO of investment firm SoftBank, saw his net worth plunge by $5.5 billion, marking the largest single-day loss among global billionaires. SoftBank's shares dropped 8.5% on Tuesday, with the company's stock down over 17% in the past five days. Despite this decline, SoftBank shares have still managed a 15% gain for the year. The wealth loss coincided with broader declines in Asian technology stocks following a long weekend. The sell-off affected SoftBank due to its extensive, debt-funded investments in artificial intelligence, particularly its 87% stake in Arm Holdings and its $64.6 billion investment in OpenAI, which leaves its shares highly sensitive to AI sector performance.\n\nMeanwhile, Lee, executive chairman of Samsung Electronics, experienced a $2.8 billion drop in wealth, ranking as the fourth-largest billionaire loss worldwide. His net worth was $29.4 billion at the time of publishing, placing him at 80th globally. Samsung's stock fell by more than 8% on the same day as Asian stocks slid to a two-month low, amid a sharp decline in chipmaker shares triggered by reports of rapid technological progress by Chinese rival ChangXin Memory Technologies. This development has raised concerns about potential Chinese firms closing the technology gap in the AI hardware sector. Charu Chanana, chief investment strategist at Saxo, noted that investors are becoming increasingly cautious about the AI trade, with three other top wealth losers on Tuesday all being from the U.S.: Oracle's Larry Ellison, Dell Technologies' Michael Dell, and Amazon's Jeff Bezos, who lost $4.4 billion, $3.9 billion, and $2.6 billion, respectively.",
