Billionaires and Tech Titans Flock to X as Musk Declares It the Global Town Square
In the space of just a few weeks in July 2026, some of the world’s most powerful and private figures made a highly visible move onto X. Mark Zuckerberg returned after years of near-silence. Nvidia chief Jensen Huang opened an account and posted for the first time. Bernard Arnault, the 77-year-old chairman of LVMH and one of Europe’s richest men, created a verified profile to speak directly to the public. Even the restaurant chain Denny’s joined the mix. X’s head of product, Nikita Bier, summed it up in a widely shared post listing the arrivals and adding a simple welcome: “Welcome to the global town square.” Elon Musk responded with characteristic brevity, reinforcing the line he has used for years: “𝕏 is the global town square.”
The cluster of high-profile activity has been interpreted by supporters as validation of Musk’s long-standing claim about the platform’s unique role. When the people who run the largest technology companies, the biggest luxury conglomerates, and major consumer brands choose to speak on X, it strengthens the argument that real-time global conversation still concentrates there.
Jensen Huang’s debut stood out for its substance and timing. On July 24 the Nvidia CEO, whose company sits at the center of the artificial intelligence boom, used his first post to share a letter titled “Open Weights and American AI Leadership.” Signed by Nvidia and more than two dozen other organizations including Meta, Microsoft, IBM, Dell, Hugging Face, and the Linux Foundation, the letter argued that the United States should support both frontier closed models and open-weight models. Huang wrote that AI would transform every industry and be built by every country, adding that open models strengthen safety, cybersecurity, innovation, and national sovereignty. “The world needs both frontier closed models and frontier open models,” he stated. The post quickly drew millions of views. Musk publicly agreed that Huang was right. For a chief executive who had previously avoided the platform, the choice of venue for a policy-heavy message about the future of AI carried symbolic weight.
Zuckerberg’s activity followed a different pattern. The Meta CEO had largely stayed away from X for years even as he built Threads as a competitor. In early July he returned to promote Meta’s Muse AI models. Later in the month he posted again to highlight a Wall Street Journal opinion piece he authored titled “The AI Future Is for Everyone,” promising more writing on a positive vision for superintelligence. The posts generated substantial engagement and drew pointed replies from X executives and users noting the irony of the Facebook founder seeking reach on a rival platform. Bier’s light-hearted suggestion that creator monetization could be enabled on Zuckerberg’s account captured the tone of much of the reaction: amused recognition that even the operator of massive competing networks still found X useful for distribution.
Bernard Arnault’s appearance was perhaps the most unexpected. The LVMH chairman had long avoided personal social media. After the French newspaper Le Monde published a six-part investigative series examining his business influence, political connections, and alleged tensions among his five children over succession, Arnault responded with a three-page open letter. Posted first through LVMH’s official channels and titled “Merci,” the letter adopted a sarcastic tone. Arnault mocked the description of his family as “the last royal family of France,” rejected claims of internal plotting, and insisted that ordinary family conversations—including Sunday calls among his children who run various LVMH houses—were being mischaracterized as intrigue. “Those who are betting on a rift in a family to sell newspapers will be waiting a long time,” he wrote. The following day he launched his personal verified account @BernardArnault and posted a note thanking the public for supportive messages. The move marked a rare instance of one of the world’s most private billionaires choosing direct digital engagement to counter traditional media narratives.
Bier’s inclusion of Denny’s alongside the tech and luxury titans underscored the breadth of the moment. The range—from AI chipmakers and social media founders to a French luxury patriarch and an American diner chain—illustrated the platform’s claim to function as a shared public space rather than a niche network for any single demographic.
Musk has described X as a global town square since shortly after acquiring the former Twitter. The phrase is meant to evoke an open place where people of different views, languages, and statuses can speak, with the platform providing the digital equivalent of a public gathering point. In practice this has meant reduced content moderation compared with many competitors, the introduction and expansion of Community Notes for crowd-sourced context, emphasis on real-time conversation, and efforts to build features around video, messaging, payments, and AI. Critics argue that the reality falls short of the ideal: algorithms still shape visibility, the owner’s own posts carry outsized influence, and the environment can be chaotic or hostile. Supporters counter that no other major platform currently concentrates journalists, policymakers, executives, creators, and ordinary users in the same real-time stream to the same degree.
The recent wave of elite arrivals arrives against a backdrop of intensifying competition in social media and artificial intelligence. Meta continues to push Threads and its own AI efforts. Traditional news outlets remain important but face declining trust and reach among certain audiences. Direct communication on X allows figures like Huang, Zuckerberg, and Arnault to bypass intermediaries, control messaging, and measure immediate reaction. For companies and individuals whose statements can move markets or shape policy debates, that combination of speed and scale remains compelling.
Whether the pattern continues will depend on multiple factors. Sustained participation by high-profile accounts, the quality of discourse that results, the platform’s ability to manage spam and abuse at scale, and broader regulatory and cultural pressures all matter. One week of notable sign-ups and returns does not permanently settle the question of which digital spaces function as genuine public squares. Yet the fact that leaders who already command enormous attention and resources still choose X when they have something consequential to say is difficult to dismiss.
In the AI era, where questions of open versus closed models, national technological sovereignty, corporate succession, and the future of human-machine collaboration are being contested in real time, the venues where those conversations occur take on added importance. Musk’s repeated assertion that X is the global town square is, at bottom, a claim about where the important discussions of the moment are happening. The recent decisions of Zuckerberg, Huang, Arnault, and others to participate there have given that claim fresh evidence, even as debates about the platform’s strengths and shortcomings continue.
