Mark Zuckerberg returned to Elon Musk’s X after three years in 2026, Meta CEO tells its these engineers and researchers who made him do it
Facebook founder Mark Zuckerberg has resumed his activity on Elon Musk’s social network X in 2026, ending a three-year hiatus away from the rival microblogging platform. He originally restarted posting on the platform to announce news regarding Muse Spark 1.1 AI model. Since then, Meta CEO has been a regular on the microblogging website. His latest post was on September 9 when he introduced “Muse, the personal agent that understands your goals and works 24/7 to get things done for you.” Around the same time, he was asked on a podcast why he chose to cross-post updates on an opposing network despite running Meta’s direct alternative, Threads. Rather than using the service purely for personal promotion, Zuckerberg revealed that the decision came down to reaching specific engineering talent and researchers who remain deeply rooted on X.
