SoftBank Group Corp is discussing an additional $30 billion investment in OpenAI, aiming to raise up to $100 billion, valuing the company at $830 billion. SoftBank shares rose over 3% before the bell. CEO Masayoshi Son’s focus on AI led to a $41 billion investment in OpenAI in December.

OpenAI faces escalating costs to train and operate AI models amidst competition from Google. SoftBank, up 3.5% in Tokyo, declined to comment. Son struggled to secure funds for the last investment, halting most other deals at SoftBank’s Vision Fund. Both firms are involved in Stargate, a $500 billion project for AI data centers.
