Who would have thought that less than a century ago we used whale oil to light our homes. Today, the rise of smart cities is becoming more and more relevant in our daily lives. Technology continues to advance, and with it, more efficient and effective mechanisms have been created to manage our homes and cities. These three smart city stocks are attracting attention, have had an incredible growth story, and have a very good futures ahead. It is worth considering adding them to our portfolios. Let’s take a look.

Xiao-I (AIXI)

Xiao-I Corporation (NASDAQ:AIXI) is one of the most prominent companies in China’s artificial intelligence landscape. The company is making waves with its revolutionary Hua Zang Universal Large Language Model Ecosystem.

Financially, the company has experienced remarkable growth. This includes significant revenue growth, strategic partnerships with government entities and substantial investments.

Recent milestones include the opening of EHang’s first European UAM Center in Spain, an initiative that integrates eVTOL aircraft with airport infrastructure. In addition, the EH216-S obtaining the Type Certificate from the Civil Aviation Administration of China (CAAC) is a landmark achievement in the aviation sector. This makes it the first unmanned eVTOL qualified for commercial passenger operations in China.
