SoftBank Group is trading 9% down today at ¥5,424 as investors reassess lofty AI-related valuations and the company’s heavy exposure to Arm and OpenAI.

  • The move extends a roughly 20% slide over the past week, fueled by broader weakness in global technology and semiconductor shares.
  • Market sentiment has shifted toward profit-taking in major AI names following recent sector-wide routs and valuation concerns.
