AMD Shares rose 11% on Wednesday, continuing a major rally since OpenAI announced plans to buy billions of dollars of artificial intelligence equipment from the chip maker earlier this week.
On Monday, the ChatGPT maker signed a deal to potentially own 10% of AMD, depending on share price and partnership phases.
AMD now has a market cap of $380 billion after rising 4% on Tuesday and 24% on Monday. Shares are up 43% so far this week, their best weekly gain since April 2016.
Historically closely linked partnership with OpenAI Nvidiahas increased investors’ confidence that AMD will be a viable rival to Nvidia in AI chips.
AMD CEO Lisa Su told reporters on Monday that the deal was a “win-win” and that the AI chips were good enough to be used in “scale deployments” or very large data centers of the kind that OpenAI and cloud providers are building.
Nvidia CEO Jensen Huang reacted to the deal on CNBC’s Squawk Box on Wednesday, saying it was “surprising.”
“Given that they are so excited about their next-generation product, this is creative, unique and surprising,” Huang said. “I’m surprised they gave away 10% of the company before they even started it. Anyway, I guess that’s smart.”
