Weibo Corporation (WB-SW), the Chinese social media giant often referred to as China's Twitter, saw its stock soar 5.21% in pre-market trading on Thursday. The surge follows the company's release of better-than-expected fiscal first-quarter results and its emphasis on AI integration.

The company reported quarterly revenue of $396.9 million, up 0.34% year-on-year and beating analyst consensus estimates of $394.2 million. Adjusted earnings per share came in at 45 cents, also surpassing the expected 38 cents. Weibo's user engagement metrics showed positive trends, with monthly active users (MAUs) reaching 591 million in March 2025, up from 588 million a year ago, while daily active users (DAUs) increased to 261 million from 255 million.

Investors seem particularly encouraged by Weibo's focus on AI integration and product improvements. CEO Gaofei Wang highlighted the company's efforts in integrating social features and upgrading its recommendation system. Notably, Weibo has made its AI-powered search function, Weibo Intelligent Search, available to all users, resulting in significant growth in both user base and daily search queries. The company's solid ad business performance and improved operating efficiency, coupled with its strategic investments in AI technology, appear to have bolstered investor confidence, driving the stock's impressive pre-market rally.
