Japanese giant Softbank Group CEO Masayoshi Son rejected concerns about a bubble in artificial intelligence investment, calling such doubts "a foolish question." Son sold the entire stake of Softbank in Nvidia for $5.83 billion to free up capital for a massive $22.5 billion funding commitment to Sam Altman’s OpenAI. Softbank also liquidated $12.73 billion worth of T-Mobile stock between June and December and tapped loans backed by other holdings, including chip designer Arm. Son said that AI will transform lives completely and generate profits. He estimated that close to $5 trillion in annual global investment will be needed to expand data centers, increase chip production, and build energy systems to support AI. He predicted that by the year 2040, around 20% of the world’s GDP will be replaced by AI-related industries. Softbank has invested $34.6 billion in OpenAI and recently reported profits soaring nearly five-fold to 5 trillion yen ($32 billion) for the fiscal year through March, driven by AI investments.
