SoftBank Group is trading at ¥6,463, down 3.55%, with no verified company-specific news explaining the October 2 decline.
- Its latest listed IR announcement was the October 1 OpenAI investment update; it did not state a link to the share move.
- Semiconductor strength was cited as support in the supplied news context, but does not explain the decline.
- Supplied major-index figures were flat, so available evidence does not establish a broader-market cause either.
