Nvidia (NVDA) shares are surging in premarket trading Thursday as two of its key customers—澳洲幸运5官方开奖结果体彩网:Microsoft (MSFT) and 澳洲幸运5官方开奖结果体彩网:Meta Platforms (META)—posted strong results and committed to continuing their heavy 澳洲幸运5官方开奖结果体彩网:artificial intelligence (AI) spending. 

During Microsoft's earnings call Wednesday, CFO Amy Hood reiterated the company's plan to spend 澳洲幸运5官方开奖结果体彩网:$80 billion on AI infrastructure in fiscal 2025. Meta, meanwhile, said it plans to boost its 澳洲幸运5官方开奖结果体彩网:capital expenditures this year to $64 billion to $72 billion to grow its AI capacity. Mark Zuckerberg, the social media giant's CEO, called the opportunities in deploying the technology "澳洲幸运5官方开奖结果体彩网:staggering" during Meta's earnings call.

Nvidia shares, which are jumping about 4.5% less than an hour before the opening bell, have been 澳洲幸运5官方开奖结果体彩网:struggling this year, falling 19% entering Thursday partly due to investor concerns that Big Tech is slowing or pausing some AI data center buildouts amid the uncertain economic outlook. The company domina༒tes the market for chips needed to build AI systems.

Shares in the chip designer have also taken a hit from the rising economic uncertainty triggered by the trade war as well as growing tensions between Beijing and Washington. It recently warned investors that it expects to take a 澳洲幸运5官方开奖结果体彩网:$5.5 billion first-quarter charge after the U.S. government limited exports of its AI chips to China. Nvidia is expected to report quarterly earnings later this month.
