SoftBank Group is reportedly in discussions to invest up to $30 billion in OpenAI, the company behind ChatGPT, according to the Wall Street Journal. This move would significantly bolster SoftBank's existing stake in the AI firm. OpenAI is currently pursuing a broader fundraising initiative, aiming to secure up to $1 trillion in new capital. If successful, this funding round could elevate OpenAI's valuation to around $8.3 trillion.
