Sources close to the transaction revealed to CNBC that SoftBank recently transferred a final tranche of $22 billion to $22.5 billion, completing its multi-phase investment strategy. This latest funding round pushes SoftBank's ownership stake in the ChatGPT creator above 10%, demonstrating the company's robust confidence in OpenAI's transformative potential.
