In an interview with CNBC, Short Hills Capital’s Steve Weis says Google is on borrowed time thanks to Microsoft’s Bing AI.

Weis discussed Google’s monopoly in the search and advertising market and how the company’s approach is different than Microsoft’s. Weis says that while Microsoft’s AI-powered Bing isn’t quite ready for primetime, at least Microsoft is innovating and launching new products. In contrast, he says Google is not really launching anything new.

As a result, Weis thinks Microsoft’s approach may be enough to pull advertisers away from Google:

“So that’s enough for advertisers in an already weak advertising market to say, ‘you know what? We’re not paying monopoly prices anymore, cause now we’ve got a legitimate contender,” which is Bing,” Weis said in the interview.

“So I believe that is going to pressure Google already. And Google has not launched products. So there aren’t many monopolies in tech that survive the test of time. Google is, I think, on borrowed time in that regard.”

Weis’ comments echo the sentiments of some Googlers who believe the company has lost its edge and was caught flat-footed by Microsoft.
