World's most valuable company beats expectations again in defiance of AI bubble fears

The world's most valuable company has reported another series of expectation-beating results, heading off fears of the AI bubble bursting, for now.

Nvidia's revenue reached $57bn in the three months to October, higher than Wall Street estimates and the company's own guidance. That's up a whopping 62% on the same time last year, and has been described by the business as an "outstanding" quarter.

It matters as Nvidia has powered the artificial intelligence (AI) boom through its computer chips, which are key parts in AI chatbots such as ChatGPT.

Nvidia has major tech companies as clients and acts as a good proxy for whether the tens of billions of dollars invested in AI is paying off. Its chief executive, Jensen Huang, has been described as the Godfather of AI and watch parties were organised for those looking to follow the Wednesday evening announcement.

The company has been a massive beneficiary of the push to put money into AI, with its share price reaching stratospheric highs. In October, it became the first worth $5trn (£3.83trn), about the size of the German economy, Europe's largest, and double the UK's benchmark stock index, the FTSE 100.

What's been announced? Revenue from data centres reached a record high of $51.2 bn, more than £10bn higher than the three months previous. The outlook is for continuing strong sales in the final three months of the financial year, as the company forecasts revenue will be roughly $65bn.

Mr Huang said sales of its blackwell chips are "off the charts" and its cloud graphic processing chips (GPUs) are "sold out".

Why it matters Developing AI infrastructure, like the construction of data centres, has been a significant contributor to US economic growth, as measured by gross domestic product (GDP). A faltering of AI expansion, therefore, impacts the US economy, the world's largest, which in turn affects the UK and global economies.

Anxiety around the massive valuations tech companies have accrued, on the hope of AI revolutionising the world, is likely to be staved off by the results announcement. A fall in these tech company valuations could have meant a drop in the value of pension pots or savings.

Just seven dominant tech companies, many of which have borrowed to invest in AI, make up more than a quarter of major US stock index, the S&P 500. In the last year alone, Nvidia's share price has risen more than 230%.

Some, including US trader Michael Burry, famous for being played by Christian Bale in the Hollywood film The Big Short, have effectively bet that Nvidia's share price would fall. Addressing the topic of an AI bubble, Nvidia's founder, Mr Huang, said, "From our vantage point, we see something very different".

What next? Regardless of the figures released on Wednesday evening, significant market moves were anticipated, given the attention paid to the results and the significance of the company. Nvidia shares rose as much as 4% in after-hours trading.

The results also boosted the share price of its chip-making competitors like Broadcom and Advanced Micro Devices. For now, the AI bubble remains intact..
