SoftBank's market value halves from June peak amid AI debt fears

SoftBank Group shares fell 6.9% on Thursday to ¥4,305, half their record close on June 2, cutting its market value to about $157 billion, Bloomberg reported. The cost of insuring its debt hit a four-year high on Tuesday. SoftBank has committed $64.6 billion to OpenAI, funded partly by an $11.1 billion junk bond sale and loans backed by shares.
