Bottom line: US tech companies argue that blanket regulation of open-weight AI will stifle innovation and worsen security risks from concentration in few proprietary systems.
More than 20 technology companies, including Nvidia, Microsoft, Meta, and Palantir, published an open letter to US policymakers on July 24, 2026, calling for no hasty restrictions on open-weight AI models. The signatories fear that sweeping bans will suffocate competition and relocate innovation abroad.
The signatories ground their position in a central security argument: concentrating advanced AI capabilities behind a few closed models increases the risk of hacking and misuse. The open letter states explicitly: “Relying exclusively on closed models is not inherently secure: they can be hacked or misused, or fail in ways that outside parties cannot detect.”
Security concerns regarding the unauthorized copying of model architectures—a procedure known as distillation—should, in the signatories’ view, be addressed through targeted legal and commercial frameworks, not blanket bans. The group argues that US leadership in AI depends on building a “strong, open ecosystem that spreads into every sector” to create opportunities for innovation and prosperity nationwide.
The letter received prominent support from OpenAI leadership. Greg Brockman, President of OpenAI, stated that his company believes in broad access and was not involved in discussions with the US government about banning Chinese open-weight models. Sam Altman, CEO of OpenAI, welcomed the letter and emphasized that the US should succeed with both open and proprietary models equally.
The appeal from 20+ companies follows a separate open letter from nearly 200 companies from Silicon Valley, including Proton and Y Combinator. This group also warned that restrictions on access to international open-weight models could harm the development of American startups, arguing: “American leadership requires two things: world-leading American open-weight models and continued access for US developers to open models already available globally.”
