Bollcoin, October 23: According to Bloomberg, SoftBank Group shares fell 6.9% on Thursday and are down 50% since hitting a record high on June 2. Rising borrowing costs have deepened investor concerns over the sustainability of its massive AI investments. Four months ago, SoftBank briefly overtook Toyota Motor to become Japan's largest company by market value; now, at about 24.7 trillion yen (roughly $157 billion), it has fallen behind Hitachi and Recruit Holdings.
