  "account": "SoftBank Group Corp.'s stock experienced a significant 9.3% decline, reaching ¥4,856, as AI-linked equities faced a multi-day downward trend. The decline was primarily triggered by a sharp sell-off in U.S. semiconductor stocks, which then spread to regional markets due to unexpectedly high U.S. inflation rates. These rates suggested a higher likelihood of more interest rate hikes by the Federal Reserve, leading to increased expectations of higher financing costs.\n\nReports surfaced that a Chinese memory chipmaker had made substantial progress in developing high-performance chips, which further unsettled tech stocks by raising concerns about heightened competition and potential price erosion in the global AI hardware supply chain. SoftBank's substantial exposure to the AI sector, particularly its 87% stake in Arm Holdings and a $64.6 billion investment in OpenAI (representing about 13% ownership), made its stock particularly vulnerable to any negative sentiment toward AI.\n\nRecent disclosures that OpenAI's annualized revenue was lower than the previously estimated $70 billion led investors to question whether the returns from SoftBank's concentrated AI investments could sufficiently cover the high-yield debt used to finance it. Consequently, credit default swaps for SoftBank had risen to their highest levels in years, indicating growing unease within credit markets about the leverage in SoftBank's AI strategy.\n\nThis heightened financial unease, combined with the anticipation of further Federal Reserve interest rate increases and the associated higher financing costs for AI investments, exacerbated the negative sentiment. As a result, SoftBank's stock plummeted alongside other technology-focused companies in Japan. The broader market also reflected this downturn, with Japan's Nikkei 225 experiencing a more than 4% drop, driven by losses in the technology sector. Other prominent Asian technology companies also witnessed sharp declines on Thursday.",
