SoftBank Group is trading at ¥6,292.00, down 3.16%, amid pressure from the Arm-Qualcomm trial. - Qualcomm alleges Arm withheld contractually required chip-testing tools; Arm denies breach. SoftBank’s roughly 87% Arm stake exposes asset value to potential legal or reputational fallout. - Japanese shares offered little support amid profit-taking and selling in AI and semiconductor stocks after recent gains. - SoftBank’s final $10 billion OpenAI tranche is context for investor concerns about scale and financing, not a new October 6 announcement.
