Weibo is China's dominant public social media platform, roughly analogous to Twitter/X, where users post short messages, photos, videos, and live streams and follow others in an asymmetric relationship. The platform's core identity is real-time public discourse — when news breaks or a celebrity scandal erupts, it trends on Weibo first. This "hot search" franchise, combined with a dense ecosystem of celebrities, key opinion leaders (KOLs), media outlets, and government agencies, makes Weibo the default destination for public buzz in China. As of December 2025, Weibo had 567 million MAUs and 252 million average DAUs. Weibo generates roughly 85% of revenue from advertising and 15% from value-added services (VAS). On the advertising side, Weibo sells promoted feed ads via real-time bidding, social display ads, and sponsored placements in trending topics and search results to brands, e-commerce platforms, and agencies. Content marketing campaigns built around celebrities, KOLs, and product launches consistently represent about half of total ad revenues and are Weibo's core differentiator. Alibaba is Weibo's largest single advertiser. VAS includes paid memberships, game-related revenues, and virtual gifting in live streams. Weibo's key strategic initiatives include a homepage revamp shifting from a relationship-based feed to an interest-based recommendation feed to compete more directly with Douyin, investment in AI-powered video creation tools, and an AI-driven search product called Weibo Zhisou that crossed 80 million MAUs in late 2025.
