Key takeaways

  • X has become the primary real-time channel where frontier AI announcements, arguments, and high-profile exits reach the public first.
  • On Tuesday, Anthropic researcher Jacob Coxon posted his resignation and a thread on safety concerns on X, drawing more than 100 million views.
  • X's dominance with the AI community is strong, but its general-user footing is narrower, with Similarweb data through January 2026 showing Meta's Threads at 141.5 million daily active mobile users versus X's 125 million.
  • OpenAI acquired the X-based live show TBPN for a rumored price in the 'low hundreds of millions,' per the Financial Times.
  • The key story to watch is X's integration into Musk's xAI infrastructure, which will determine whether X's hold on the AI community tightens.

Two years after rival platforms threatened its relevance, X has carved out a position no competitor has replicated: the real-time channel where frontier AI announcements, arguments, and high-profile exits reach the public before the rest of the information ecosystem catches up. The clearest recent measure of that position came on Tuesday, when Anthropic researcher Jacob Coxon posted his resignation on the platform alongside a thread detailing safety concerns, drawing more than 100 million views. A second Anthropic employee then wrote that he believes there is a greater than 10 percent chance artificial intelligence could kill all humans within the decade.

What the concentration reflects

The dynamic predates Musk. Researchers and technology figures were already networked on the platform before his acquisition closed, which landed one month before OpenAI released ChatGPT. That timing bound an already-connected AI community to X at the moment the field accelerated. Andrej Karpathy, an Anthropic AI researcher, coined the term "vibe coding" in an X post in 2025, naming one of the central trends in AI enterprise adoption. Nvidia chief executive Jensen Huang launched his X account in July alongside a post backing open AI models. Apple's new chief executive John Ternus has joined the platform, and Meta's Mark Zuckerberg returned to posting on X this year after leaving his account largely dormant since he created it in 2009.

The numbers that frame the niche

X's hold on the AI community is real. Its footing with general users is narrower. Similarweb data through January 2026 placed Meta's Threads at 141.5 million daily active mobile users against X's 125 million. Heavy investment in live video produced shows such as TBPN, Stabledash, and MTS Live, aimed at AI insiders. The viewership does not rival cable television, but audience density attracted OpenAI, which acquired TBPN for a rumored price in the "low hundreds of millions," per the Financial Times.

What to watch

The integration of X into Musk's xAI infrastructure is the story to follow. xAI acquired X, saying the companies would combine their data, models, computing capacity, and distribution. Grok, xAI's AI model, can already connect to X accounts and read user timelines in real time. How far that integration extends will determine whether X's hold on the AI community tightens or whether the broader user base continues drifting toward Threads.
