X (Formerly Twitter)

X, formerly Twitter, is a major global platform for real-time information, public discourse and social interaction, and is gradually expanding into financial and AI services. X has recently deepened the integration of Grok AI, Cashtags, subscriptions and its "Active Fans" feature, while also becoming a source of social-sentiment analysis and investment intelligence. At the same time, it faces a proliferation of AI-generated content and spam, along with content-governance challenges and legal disputes across jurisdictions. Vitalik has also proposed developing X into a global AI governance platform. The platform's efforts to balance commercialization, information quality, freedom of expression and AI governance remain important to watch.
