Tesla is building its own chip fab. The Senate just approved AI. The chip export rule is dead.

Three moves that reshape the AI hardware race, U.S. policy, and which AI tools are now officially in government hands.

🖥️ Tesla's Terafab Launches in 7 Days

Decoded: Elon Musk announced on March 14 that Tesla's Terafab project — a dedicated AI chip fabrication facility — will launch within seven days. Terafab is Tesla's bid to build its own AI chips in-house, ending reliance on Nvidia and TSMC for the compute powering Dojo and xAI's Grok infrastructure.

Why it matters: Every hyperscaler building in-house silicon (Apple, Google, Amazon, Meta) has reduced unit economics and reduced Nvidia's leverage. Tesla entering chip fabrication is the same playbook — and it puts another large customer on a path away from the Nvidia stack. Watch NVDA reaction when the launch drops this week.

🏛️ Senate Authorizes ChatGPT, Gemini, and Copilot for Staff

Decoded: The U.S. Senate issued a memo authorizing staff to use ChatGPT (OpenAI), Gemini (Google), and Microsoft Copilot for official work — drafting documents, summarizing information, preparing briefing materials, and conducting research. Claude (Anthropic) was notably excluded after Trump called Anthropic "left-wing nut jobs" on Truth Social.

Why it matters: Government AI adoption is now official at the legislative level. For MSFT and GOOGL, this is a meaningful enterprise validation signal. For Anthropic, the exclusion is a political liability that could affect future federal contracts — a real risk given their Pentagon ambitions. The battle for government AI isn't just about capabilities anymore.

📉 Commerce Department Kills the Global AI Chip Export Rule

Decoded: The U.S. Commerce Department withdrew its planned rule that would have required permits for AI chip exports to any country in the world. The rule — drafted under the Biden administration — was pulled on March 13 with no replacement announced. A former official cited internal disagreements within the Trump administration over how to balance AI supremacy goals with national security restrictions.

Why it matters: This is a direct win for Nvidia, AMD, and the broader semiconductor supply chain. The rule would have created significant friction on international sales. Its withdrawal removes a major overhang on semiconductor revenue guidance for 2026. Keep an eye on how NVDA addresses this on its next earnings call.

That's your Sunday signal. See you tomorrow.
