Nvidia's $100 billion investment in OpenAI caused global semiconductor stocks to rally. CNBC's Arjun Kharpal breaks down what the deal could mean for the European chip sector.

Brussels

Nvidia and OpenAI's new partnership is drawing attention across global markets, with Nvidia shares rising and analysts considering the wider effects on the semiconductor supply chain. The deal is expected to reinforce Nvidia's leading position in artificial intelligence, while also providing OpenAI with early access to advanced Nvidia technology. 

European semiconductor companies such as ASML and ASMI could benefit from increased demand for manufacturing equipment and technology, though the full impact will depend on how the partnership develops and when new data centers come online. The agreement also emphasizes the dominance of American firms in AI infrastructure, potentially challenging European AI startups that lack similar resources.

How Nvidia and OpenAI's deal could impact European chip firms

Arjun, we saw this story having an impact on Wall Street yesterday, Nvidia shares closing higher by about 4%. It is also impacting some of the moves in Asia this morning. How likely is it that it could also have ramifications for European moves? Look, it's a big deal, of course, across the semiconductor supply chain. If we think about Europe's position at this point in time, if the view is that the use and development of semiconductors is going to continue to boom, then this is going to rely on the entire supply chain, of course, manufactured by TSMC, potentially others as well. But then, of course, TSMC will need to build out that capacity, buying equipment, say, from ASML, using technology even from ASMI as well. And so there are a number of names in the European semiconductor space over the longer term that could see benefits right now. I think at this point in time, there's still a lot of details to be worked out, how exactly this money will be deployed, the timelines for bringing these data centres online. And so I think that is going to really determine the impact over the longer term on some of the European semiconductor names in particular. For Nvidia, at this point, it cements Nvidia's position at the centre of this AI boom. And we really know that Europe doesn't have a competitor to Nvidia. For OpenAI, again, it puts them in a very prominent position. They get first access, really, to a lot of this Nvidia technology as well. And this has laid down the challenge to some of OpenAI's rival, the likes of Anthropic, but also Mistral here in Europe, which has nowhere near the capital that OpenAI is getting access to at this point as well. And the other part of the equation is we've heard a lot of the hyperscalers and OpenAI talk about the fact there is a shortage of computing capacity. Being able to build that themselves with Nvidia chips also gives OpenAI another advantage here, again, at the expense potentially of some of those other European players as well. So again, it's cementing what is seen as the American dominance in this AI infrastructure build-out. But there will be a few European companies likely in the supply chain of semiconductors that will be able to participate in this, Sylvia.
