The signing brought together an unusual lineup of tech power players, including SpaceX's Elon Musk, Meta's Mark Zuckerberg, Anthropic's Dario Amodei, Nvidia's Jensen Huang, OpenAI's Greg Brockman and Google's Sundar Pichai. Johnson described the accord as a "joint commitment" and "statement of principles" focused on what Trump calls "super intelligence," his preferred term for advanced AI. The standards are voluntary, not law, so nothing forces the companies to follow them.

The agreement comes as pressure builds nationally for tighter rules on how AI gets built and deployed. Right now there's no binding federal law spelling out what these companies can and can't do with the technology, so a handshake deal between the president and the industry's biggest names carries real weight, even without teeth. For everyday people, it means the companies shaping chatbots, self-driving systems and search tools have agreed, at least on paper, to police themselves. Whether that holds up depends on whether they stick to it.
