Recently, internet giants such as Baidu, Alibaba, and Tencent have all launched new versions of their map products enhanced with AI capabilities to adapt to the advent of the mobile internet era on a large scale. This marks a new phase in the fierce competition among BAT groups in the map business. Each company has different strategies in the AI map sector; Baidu focuses more on the B2B market, AutoNavi emphasizes consumer-oriented travel, while Tencent balances between B2B and consumer markets. This indicates that maps will no longer be merely navigation tools but will become a new gateway for internet users to access various services, potentially spawning hundreds of billions of dollars in business opportunities. The arrival of the AI era has breathed new life into the map business, and the battlefield of BAT has shifted once again to this domain.
