Understanding the Tesla-Samsung

Tesla AI6 Chip Deal

What’s the Tesla AI6 Chip Deal About?

On July 26, 2025, Samsung announced a $16.5 billion contract to manufacture semiconductors for a “large global company,” keeping the client’s identity confidential until 2033 to protect trade secrets. Tesla CEO Elon Musk confirmed the deal on X, revealing that Samsung’s new chip factory in Taylor, Texas, will produce Tesla AI6 chip, critical for its Full Self-Driving (FSD) system and AI initiatives. The contract, running through December 31, 2033, represents 7.6% of Samsung’s 2024 revenue, making it the largest foundry order in the company’s history.

Why It Matters

For Tesla, this deal secures a stable supply of advanced chips, reducing reliance on Taiwan Semiconductor Manufacturing Company (TSMC), which will produce Tesla’s AI5 chips. Samsung’s collaboration allows Tesla to optimize manufacturing efficiency, with Musk personally overseeing progress to ensure the Tesla AI6 chip meet Tesla’s ambitious AI goals. For Samsung, the contract is a lifeline for its struggling foundry business, which has lost ground to TSMC and SK Hynix in the AI chip race. The deal could signal a turnaround, boosting Samsung’s credibility and market share in the $600 billion global foundry market.

Key Details

Scope: Samsung will produce Tesla AI6 chip using its upcoming 2-nanometer (2nm) process at its $37 billion Taylor, Texas, facility, set to begin operations in 2026.
Timeline: The contract spans from July 2025, to December 2033, providing long-term revenue visibility.
Impact on Samsung: The deal could generate 2.5 trillion won ($1.8 billion) annually, about 10% of Samsung’s foundry revenue, helping offset losses estimated at 5 trillion won ($3.6 billion) in H1 2025.
Impact on Tesla: Secures 50 million chips annually, far exceeding the 3.8 million needed for 2 million vehicles, suggesting broader AI applications beyond automotive.

Stock Reaction: Tesla and Samsung

Tesla Inc. (NASDAQ: TSLA)

Tesla’s stock rose 1.9% in pre-market trading on July 28, 2025, reflecting a more muted response compared to Samsung. This follows a 5% drop earlier in the week after Musk warned of “tough quarters ahead” due to softer EV demand and expiring tax incentives. The deal is highlighted as a “massive AI play.” Estimating it secures 50 million 2nm chips annually, far beyond automotive needs, suggesting applications in Tesla’s AI and robotics ventures.

Despite the initial bump, Tesla’s stock has been volatile, down 12% year-to-date due to EV market slowdowns and tariff concerns. The deal’s long-term focus (production starts in 2027–2028) limits immediate impact, and Tesla’s history of missing targets adds uncertainty. However, securing a dedicated chip supply reduces supply chain risks, a critical factor considering U.S.-China trade tensions.

Samsung Electronics (KRX: 005930)

Samsung’s stock soared 6.8% on July 28, 2025, reaching its highest level since September 2024, with trading volume spiking to over 18 million units. The surge reflects investor optimism about the deal’s potential to revive Samsung’s foundry business, which holds an 8% global market share compared to TSMC’s 67%.

However, Samsung faces challenges. Its second-quarter operating profit is expected to drop 56% due to weak foundry orders and struggles in high-bandwidth memory (HBM) chips for AI, where SK Hynix leads. The Tesla deal, while significant, may not involve Samsung’s cutting-edge 2nm tech due to yield issues, potentially limiting its long-term impact. Analysts see a “sequential recovery” in H2 2025, but caution that Samsung must improve yields to compete with TSMC.

Stock Movement Analysis

Samsung’s Stock Drivers

Positive Catalysts:
- Revenue Boost: The deal adds ~10% to Samsung’s annual foundry revenue, reducing losses and boosting investor confidence.
- Strategic Win: Securing Tesla as an anchor customer validates Samsung’s foundry ambitions, potentially attracting clients like Qualcomm.
- Financial pressure relief: Samsung’s contract chip-making business has posted losses; this deal could help turn margins around.
- Long-term revenue stream: A multi-billion dollar contract extending to 2033 gives Samsung strong forward visibility.
