Huang Renxun logs into X with top-tier traffic: 580k followers in 12 hours, 33.62 million views for his first post, with Musk backing him.

12 hours, 584k followers, 584k views—this is Jensen Huang’s first day on X. The longtime Nvidia CEO who has kept the community platform on ice finally posted for the first time, sucking all the attention of the entire tech industry onto him. In his first post, he shared an open letter on open-weight AI led by Nvidia and jointly signed by 25 companies including Microsoft and Meta. Immediately after, X owner Elon Musk reposted to show support, and the line “Jensen is right” brought in another big wave of traffic.

After staying silent for so many years, Jensen Huang’s first words are traffic at an absurd scale. Nvidia CEO Jensen Huang posted his first-ever X post on July 24, 2026 (U.S. time). About 12 hours after the account went live, it surged to 584k followers. The view count for his first post also kept climbing, reaching 35 million.

What does that even mean? Even after years of running X accounts, with countless posts, the CEOs of Intel and AMD have never touched this kind of scale. The moment he posted for the first time, his traffic went over every peer in the industry.

For my first post, I’m sharing a letter @NVIDIA signed on why open models matter.

AI will transform every industry, power every company, and be built by every country.

Open models strengthen safety and cybersecurity, accelerate innovation and diffusion, and enable sovereignty.… pic.twitter.com/t02bi51N4C

Even more shocking is the speed. Earlier, Taiwanese media had captured the scene still at “more than 200,000 followers, increasing rapidly,” and after only a few hours it doubled and pushed close to 600k. The followers didn’t accumulate slowly; it felt more like they were poured directly in. This wave of traffic is hard to explain with nothing but celebrity halo—it looks more like the entire AI industry’s attention turned and pressed down on him at the same time.

His first post is an open letter

Jensen Huang didn’t use his first post to chat casually—he directly dropped an open letter. The letter is led by Nvidia and jointly signed by a total of 25 companies, including Microsoft, Meta, Hugging Face, OpenAI, and Palantir. Its core argument is just one line: open-weight AI models are a key pillar for the U.S. to maintain leadership in AI.

What people call open-weight (open-weight) models—in plain terms—means publishing the trained model parameters directly and openly, so anyone can download, fine-tune, and deploy it themselves. That’s in contrast to closed models that only give you an API while keeping their internal details hidden.

“AI will transform every industry, drive every company, and be built by every country with their own hands,” Huang wrote in the post. “Open models can strengthen safety and cybersecurity, accelerate innovation and diffusion, and enable sovereignty. The world needs not only the most advanced closed models, but also the most advanced open models.”

The real recipient of this letter is Washington. Twenty-five companies together are essentially collectively calling on regulators—don’t repeat the playbook of the 1980s. Back then, people also argued for strict restrictions on open-source software out of fear of risk, and the result nearly choked off the open ecosystem that later supported the entire software industry.

Musk reposts it—effectively pushing it one more step

Not long after the post went out, X boss Elon Musk reposted it himself, with a line: “I fully support this post; Jensen is right.” With the platform owner who controls the algorithms personally endorsing it, the post’s reach was effectively pushed through another round by the system, and the traffic snowball kept rolling bigger and bigger.

Another detail dug up by sharp-eyed netizens: Jensen Huang’s following list. He currently follows only 52 accounts. After excluding Nvidia’s own official account matrix, the rest are almost entirely tech giant CEOs and major figures in the U.S. venture capital circle, with the theme heavily concentrated on AI infrastructure. Who he follows—somewhat more honestly than what he posts—basically makes up the 52-person list of the AI compute ecosystem he has in his mind.

Someone who has left X untouched for so long, yet chooses to appear high-profile at the time when the open vs. closed AI debate is most heated, and the very first sentence stands up for the open camp. This doesn’t look like a spur-of-the-moment move; it looks more like he picked the right moment for a single decisive action. As for whether he will turn into a CEO who loves posting from now on—or whether this golden-throated opening is only for this letter—we’ll keep watching.
