Tesla shares rose 6.8% on Monday following CEO Elon Musk's weekend posts on X about the company's AI chip capabilities. Musk highlighted Tesla's advanced engineering team and plans for annual chip updates to support self-driving and robotics ambitions. The announcement underscored Tesla's push into custom AI silicon amid a broader tech rally.
On Sunday, November 23, 2025, Elon Musk posted on X, stating, "Most people don't know that Tesla has had an advanced AI chip and board engineering team for many years." He noted that the team has "designed and deployed several million AI chips" in Tesla vehicles and data centers, adding that these chips would "profoundly change the world in positive ways."
Musk revealed details on Tesla's chip roadmap, including the current "AI4" generation used in vehicles, with the fifth-generation "AI5" chip nearing tape-out—the final design stage. Development has already begun on the "AI6" chip. Tesla aims to bring a new AI chip design to volume production every 12 months, matching the update cadence of Nvidia, to advance its full self-driving features and humanoid robot projects like Optimus.
The AI5 chip will be manufactured by Samsung Electronics and Taiwan Semiconductor Manufacturing Company (TSMC) using a dual-fab strategy to scale production and mitigate risks. It is intended for use in electric vehicles for advanced driver assistance, robotics, and data centers. Musk emphasized applications such as safer driving and advanced medical care, potentially saving millions of lives.
Tesla is actively hiring chip-design talent, with Musk inviting engineers to submit evidence of exceptional ability via email. Volume production of the AI5 chip is expected in 2026 or later, before widespread deployment.
The stock surge occurred amid a market rally, with the S&P 500 up 1.5% and Nasdaq Composite up 2.6%. Tesla's shares closed above $400, though analysts note the valuation remains speculative, rooted in the company's car and battery business rather than realized AI or robotics revenue.
