Nvidia is in talks to join a funding round for OpenAI that could value the AI startup at over $100 billion. Apple Inc. and Microsoft Corp. are also considering participating in this round. The world’s largest chipmaker may contribute around $100 million. If the deal proceeds, it would mean that three of the most valuable tech companies are backing OpenAI. This move comes amid regulatory scrutiny over Big Tech’s influence on AI, with Nvidia's dominance in AI chips and Microsoft's deep integration of OpenAI’s services under particular focus. OpenAI seeks to use the new funding to expand its computing power and cover operating expenses.
