Marketers could see some champagne corks in bottles popping this weekend at the homes of Microsoft executives. 

We can attribute Microsoft's gain and Google's loss to artificial intelligence (AI), according to Microsoft Head of Search Jordi Ribas. He posted new numbers on X this week from ComScore and StatCounter to show the divide and ride the companies have endured since early 2023.

Bing has managed to grow by about 2.1% market share, according to Comscore, while Microsoft inched up 3.4%, per StatCounter.

While Microsoft climbed, Google fell slightly, by 1.2% and 6.1%, respectively, according to Comscore and StatCounter.

Microsoft reported this week that its search and news business excluding traffic acquisition costs grew 21% and 20% in constant currency driven by volume and rate growth across Bing and Edge.

“This is now the fourth consecutive year in which Bing and Edge took market share,” Ribas wrote on X.

He shared the latest numbers for several known search engines reported publicly by Comscore in the U.S., and StatCounter worldwide.

The numbers outlined a steady climb since Microsoft shipped Bing Chat and Copilot in 2023.

He also attributed the growth during the past fiscal year to innovations like Copilot Search in Bing, and the ability to power web search for third-party chatbots like ChatGPT and Meta AI.

Microsoft's Bing search engine is integrated into Meta AI's chat and across platforms such as Instagram, WhatsApp, and Messenger. The integration allows Meta AI to provide users with current and accurate information by leveraging Bing's real-time web search capabilities.

There has been some debate on where these AI chatbots get information when data is missing from Microsoft and Google AI systems.

Brett Tabke, CEO and founder of Pubcon, and founder of PHD Software Systems, a specialty software manufacturer that produced software for Commodore computers during the early years of personal computers, told MediaPost much of the data that fills of the holes comes from the CommonCrawl database when information is missing.
