Shares in Japanese tech behemoth SoftBank Group soared more than eight percent on Wednesday after US President Donald Trump announced a major investment to build AI infrastructure.

Unveiled as a joint effort involving OpenAI, Oracle, and SoftBank, Stargate’s initial phase comes with a private investment of $100 billion. Trump hailed the venture as a testament to America’s innovative strength, describing it as a game-changer for the country’s AI ecosystem.
