SoftBank CEO Masayoshi Son plans to announce a $100 billion U.S. investment over four years, focused on artificial intelligence and infrastructure. Son made the announcement during a visit to President-elect Donald Trump at Mar-a-Lago. The Japanese billionaire and Trump will jointly pledge to create 100,000 U.S. jobs by the end of Trump's term. Funding may come from sources like the Vision Fund, capital projects, or Arm Holdings, where it holds a majority stake. Portions of the investment could include previously announced funding, such as its recent $1.5 billion commitment to OpenAI.
