AI chip leader Nvidia has invested $2 billion in semiconductor design software provider Synopsys, adding to its slew of new partnerships in the artificial intelligence ecosystem amid concerns of increasingly circular deals.

The world's most valuable firm has invested billions of dollars this year in companies linked to the booming AI industry, ranging from deals allowing as much as a $100 billion investment in ChatGPT parent OpenAI to a $5 billion stake in Intel.

Shares of Synopsys rose 7% in premarket trading, while Nvidia shares fell nearly 2%. Nvidia, which is a Synopsys customer, bought the company's common stock at $414.79 per share, the companies said on Monday.
