Back in the dot-com boom era, stock splits became commonplace in response to soaring share prices. Amid the current artificial intelligence (AI) boom, a similar pattern could be developing. Already, several AI companies have split their shares, and more splits could be on the way among the others that are trading at lofty prices.

Nvidia (NASDAQ: NVDA) has been the stock everyone is talking about for quite some time -- and for good reason. The company dominates the artificial intelligence (AI) chip niche with a market share of about 80%, and this has translated into record earnings. Even better, Nvidia's focus on innovation means its dominance is likely to last.

That massive gain was largely driven by the rapid expansion of the artificial intelligence (AI) market, which drove many companies to ramp up their purchases of the company's data center graphics processing units (GPUs) to process complex machine learning and AI applications.
