Chipmaker Nvidia moved closer to becoming the first company to be valued at $5 trillion on Tuesday after announcing $500 billion in orders for its artificial intelligence processors and plans to build seven new supercomputers for the U.S. Department of Energy.

Nvidia's stock closed nearly five percent higher, adding more than $230 billion to the company's market capitalization, bringing its total value to $4.89 trillion after briefly touching $4.94 trillion.

The company's CEO, Jensen Huang, began his keynote address at a developers' conference in Washington yesterday by praising the policies of US President Donald Trump while announcing new products and deals.

Nvidia is at the heart of the global rollout of artificial intelligence. The company is making deals at a time of trade war between the US and China that could determine which technologies produced by the two countries will be most widely used worldwide.

The California-based company's stock rose 50 percent in 2025. Its market capitalization surpassed four trillion dollars for the first time in July.

The supercomputers that Nvidia is building for the Department of Energy will help the United States maintain and develop its nuclear arsenal.

The largest of these supercomputers will be built in collaboration with Oracle and will contain one hundred thousand of Nvidia’s advanced Blackwell chips.

Apple and Microsoft join the $4 trillion club

In a related development, shares of Apple and Microsoft rose on Tuesday, pushing the two companies' market value above $4 trillion for the first time.

Shares of Microsoft, the world's second most valuable company, rose 2 percent to bring its market capitalization to $4.03 trillion.

This achievement comes at a time when Apple's stock has seen a significant rise in recent weeks, as sales of the iPhone 17, which was released in September, appear to be better than its predecessors.

Apple shares rose in 11 out of the 12 trading days. The company will announce its fourth-quarter earnings on Thursday, while Microsoft will announce its earnings on Wednesday.
