AI development is accelerating — with some scientists suggesting machines will be more intelligent than the smartest humans within the next few years.

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.

These companies are getting a nice boost thanks to AI, a trend that's likely to continue thanks to their huge addressable markets.
