SoftBank shares jumped as much as 10% in Tokyo on Monday, putting the tech group on track to surpass Toyota in market value and reshuffle Japan’s corporate rankings.
The rally was driven by the AI boom and by reports that portfolio companies OpenAI and SB Energy are preparing potential U.S. listings, extending gains already building in SoftBank stock.
Toyota shares fell as much as 4.9% at the same time, widening the gap as AI-linked stocks advanced across Asia and underscoring investors’ shift toward technology exposure.
