I already have one eye on next year, looking for the most vital themes and which growth shares can outperform the rest of the market. Even though I’m still building my list, I thought it might be worth checking out ChatGPT to see if the AI ​​bot has any ideas I may have missed. The answer was quite surprising.

More of a general selection

ChatGPT told me that if he had to choose one high-conviction growth stock heading into 2026, he would choose Nvidia (NASDAQ:NVDA). As for the rationale, he talked about the company being in the heart of the AI ​​boom. Indeed, the company’s chips are widely considered to be the leading hardware for training and running generative artificial intelligence and high-performance computing workloads. Therefore, if demand for AI infrastructure continues to grow, the share price should benefit.

Given ChatGPT’s ability to process so much information, I was surprised by its rather generic choice. Nvidia has done incredibly well, up 33% this year. It has enjoyed an incredible turnaround over the last few years. For example, if you bought the stock five years ago, your gain would be as much as 1,326%!

However, I can’t say I agree with my friend AI. As I look ahead to next year, there are a few reasons why Nividia may not be as stimulating as other options.

Scope for further outperformance

Nvidia recently achieved an incredible milestone, reaching a market capitalization of $5 trillion. This is simply amazing. However, for the purposes of our discussion, it is also somewhat disturbing. U.S. stocks are so large these days that it’s harder to deliver juicy share price gains. For example, a 10% boost would boost the value by approximately $500 billion. In contrast, if the market capitalization of the stock was $50 billion, a 10% boost would mean an boost in value of $5 billion. The thing is, it’s much harder to boost a company’s value by $500 billion. As a result, this could hamper Nvidia’s stock growth next year.

Another issue is competition. The chips produced are indeed a favorite product of many customers. However, other companies are catching up, which could eat into market share in the coming year. They belong to them Advanced micro devices AND Intel. I would argue that these better growth stocks are worth considering because the companies could grow quickly by taking market share. Nvidia would do well to maintain its dominant position, not expansion.

Of course, these are just my views. Nvidia can continue to deliver massive profits, driven by mighty financial performance and increased AI adoption in the future. However, when it comes to looking for exceptional share price gains, I’m having a difficult time seeing why Nvidia is the most attractive option on the market right now.
