X (formerly Twitter)

Major global social media advertising platform competing with Meta, Google, and TikTok, with a unique real-time and cultural conversation positioning

X, formerly known as Twitter, is a global social media and advertising platform that has operated since its founding in 2006. In 2023, following Elon Musk's acquisition of Twitter, Inc., the platform was rebranded as X, with the parent entity also operating under the X name. The platform enables real-time public conversation, news dissemination, and community engagement across a massive global user base, making it one of the most influential digital media properties in the world. In the AdTech ecosystem, X offers a robust suite of advertising products that allow brands, agencies, and performance marketers to reach highly targeted audiences through promoted posts, video ads, trend takeovers, and dynamic product ads. The platform's unique strength lies in its real-time, intent-driven environment — users actively engage with trending topics, live events, and breaking news, creating high-attention moments that advertisers can capitalize on. X's ad platform supports sophisticated audience targeting based on interests, keywords, follower lookalikes, and behavioral signals. Despite significant advertiser departures following the 2022 acquisition and subsequent platform changes, X continues to operate as an active advertising platform and has been working to rebuild brand safety tools and attract advertisers back. The platform competes directly with Meta, Google, TikTok, and Snapchat for digital advertising budgets, and its positioning around real-time conversation and cultural relevance remains a core differentiator. X is privately held under its parent company, X, and is not publicly traded.
