Nvidia is reportedly in negotiations to invest up to $30 billion in OpenAI, which could value the AI startup at a $730 billion pre-money valuation. This investment is separate from a previously announced $100 billion infrastructure agreement between Nvidia and OpenAI, which involves Nvidia investing over several years to support OpenAI's supercomputing facilities. The current $30 billion deal is not finalized and may be part of future funding rounds that could total around $100 billion, involving investors like Amazon, Microsoft, and others. OpenAI's CEO Sam Altman has expressed confidence in ongoing collaborations with Nvidia, despite uncertainties about the deal's status. Meanwhile, AI stocks such as Nvidia, Microsoft, Oracle, and CoreWeave could benefit from OpenAI's near $100 billion funding round, which aims to support its aggressive data center expansion. The funding round is expected to be completed in two parts, with strategic investments from major tech firms, and could significantly impact the valuation and growth prospects of AI-related companies.
