Nvidia CEO Jensen Huang Makes First-Ever X Post Backing Open-Weight AI Letter Signed by 25 Companies

What happened

Nvidia CEO Jensen Huang published his first-ever post on X on July 24, 2026, sharing an open letter signed by 25 tech companies urging Washington not to impose premature restrictions on open-weight AI models.

Context and impact

The letter arrives as the White House accused China of stealing Anthropic model source code. Signatories argue that concentrating advanced AI in a handful of closed models creates a single point of failure that is harder to audit or defend. OpenAI, while not on the original Huang post, also backed the letter's sentiments.

Details

• 25 signatories include Nvidia, Microsoft, Meta, Dell, Palantir, Hugging Face
• Key arguments: open models strengthen safety, cybersecurity, innovation, and sovereignty
• Huang warned against repeating the mistake the software industry nearly made in the 1980s with closed ecosystems
• Letter arrives shortly after Kimi K3 — an open-weight model approaching frontier capability — triggered global market sell-off
