[Jessica Edinger]

With a CNBC your Money minute. I'm Jessica Edinger. Starting to hear a lot of AI bubble talk on cnbc.

[Mike Santoli]

There is a little bit of percolating bubble talk out there.

[MacKenzie Seagalos]

Worried about bubble like valuations forming a lot of heat in those US Tech stocks.

[Mike Santoli]

There's a bubble that is maybe, you know, overheated. Some folks are saying it's a bubble. I mean, I'd like to think that it's not a bubble. I'd like to think that there's enthusiasm now across the board. AI is really as significant as as the Internet was in the late 1990s. Even more, it could eventually end in very speculative bubble type conditions.

[Jessica Edinger]

And here's CNBC's MacKenzie Seagalos.

[MacKenzie Seagalos]

Even Sam Altman, the man who lit this fuse three years ago with chat cbt, admits that valuations are insane and calls today's frenzy a bubble, even as he insists that is the most important thing to happen in a very long time.

[Jessica Edinger]

As CNBC's Mike Santoli explains, investors are looking at a chart of the S&P 500 index over the past past couple of years and it looks a lot like it did in the late 1990s.

[Mike Santoli]

Everybody's hearing echoes of that period. Now both bulls and bears. Bears will say we have a hyper concentrated market the way we did back then. We had an Internet bubble back then. We have an AI bubble now. Very expensive valuations, all the rest of it. Or in the bulls are saying if we're going to have a rerun, we're not nearly at the end of it.
