The $5 trillion question: Is Nvidia’s skyrocketing market cap fueling the AI bubble?

Picture of artificial intelligence

Last week Nvidia hit a record milestone, by becoming the first company in the world to reach a $5 trillion market value. On Wednesday, October 29, shares of the company surged more than 3%, reaching the record high. The recent move came shortly after CEO Jensen Huang announced plans to build seven new supercomputers for the US government and Nvidia expects $500 billion in artificial intelligence chip orders. Year to date, Nvidia’s stock has climbed over 50%, largely fueled by the growing focus on AI. Is this all-time high market value here to stay or is it a sign that the AI-bubble is about to burst?

The AI Boom: What’s driving the surge?

The excitement around AI is undeniable. From Silicon Valley startups to the global tech giants, everyone is rushing to integrate AI into their products and services. At the same time billions of dollars are pouring into the AI companies from eager investors betting on growth in the sector. Nvidia’s dominance in the AI space has made it an obvious beneficiary to this trend. In some ways, it can look like a complete circle, where the different companies invest in each other back and forth. However, critics say that this practice of investment creates a misleading impression of growth and revenue as the funds flow into a system that resembles a closed loop. 

Nvidia’s chips are used not only in cloud data centers, but also by companies developing everything from self-driving vehicles to virtual assistants. As different industries continue to incorporate AI, the demand for Nvidia’s products has grown even further. Some have started to wonder is this growth is sustainable or based on a vision of a future that may never materialize.

Nvidia stock is currently trading at around $203 per share, up significantly year to date. The price to earnings ratio (P/E) is around 57. Vontobel offers a wide range of leverage products with Nvidia as underlying, allowing you to gain both long and short exposure depending on your view. 

The AI race: Hype or reality?

Nvidia is not the only company that has caught the AI wave. Companies across the tech sector are embracing the potential of AI, but few are as confident and well-funded as OpenAI. The company known most for their AI software, ChatGPT, and is backed by billions of dollars in investments from Microsoft and others. ChatGPT has become a daily tool for a great number of people, especially students and professionals. This language model has turned OpenAI into one of the most valuable AI companies in the world. It was recently announced that the company is laying the groundwork for an initial public offering (IPO) that could value the company at $1 trillion, which would be one of the biggest IPOs of all time. It is worth noting that AI’s market impact is still largely speculative. While AI has promising applications in healthcare, finance and logistics to mention a few, most AI companies have yet to prove their ability to generate consistent and significant profits. This combined with sky high valuation may lead to questions being asked about the sustainability of the sector. 

The road ahead

As Nvidia continues to soar and OpenAI prepares for a potential IPO, it is clear that the AI boom has captured the market’s imagination. As the enthusiasm in the market grows, so do the questions about the sustainability of its growth. Is Nvidia’s record market capitalization a sign of long-term growth or a speculative bet on the future of artificial intelligence, or will it expose hidden risks? In the end, the future of AI is as uncertain as it is exciting, and as history has shown, the line between groundbreaking innovation and speculative frenzy is often thin.
