Nvidia has hit a new milestone, becoming the first company in the world to reach a market value of $5tn (£3.8tn). The US chip giant has rapidly climbed from a niche graphics-chip designer to an AI titan, as euphoria about the potential of artificial intelligence keeps driving demand for its chips and propelling its stock to record highs.

The chipmaker on Wednesday became the first publicly listed company to top $5 trillion in market value, boosted by demand for its AI chips.

In this week’s edition of The Prototype, we look at why AI models struggle with finance, a revolutionary superconducting discovery, Pac-Man and more.

The artificial intelligence giant Nvidia on Wednesday notched yet another historic milestone, becoming the first company to be worth $5 trillion. The value of Nvidia alone is now worth more than the GDP of every country on earth, except for the United States and China, according to World Bank data.

Don’t let widespread enthusiasm for any one stock distract you from the most proven way to succeed as an investor.

US chip giant Nvidia will supply more than 260,000 of its most advanced artificial intelligence (AI) chips to South Korea's government, as well as Samsung, LG, and Hyundai. The companies will all deploy AI chips in factories to make everything from robots to autonomous vehicles.

Researchers from Peking University say their resistive random-access memory chip may be capable of speeds 1,000 faster than the Nvidia H100 and AMD Vega 20 GPUs.

As a key driver of the AI boom, Nvidia's share price has skyrocketed in recent years, becoming the most valuable company in history.

Nvidia became the first company to surpass $5 trillion in market value after a fresh rally driven by AI-chip demand.

The move positions Nvidia’s AI inside the cockpit, enabling Joby to handle flight hardware and certification, while Nvidia provides the brains. Also, Nvidia could become the de facto AI standard for flying cars if the sector takes off.
