Samsung Electronics has signed a $16.5 billion contract to supply semiconductors to Tesla, with the agreement effective from July 26, 2025, and running through December 31, 2033. Although the initial filing from Samsung did not disclose the identity of the client, Elon Musk later confirmed Tesla’s involvement via posts on social media. He revealed that Samsung’s new semiconductor fabrication facility in Texas will be dedicated to producing Tesla’s next-generation AI6 chips. Currently, Samsung manufactures the AI4 chip, while the AI5 is set to be produced by TSMC in Taiwan and Arizona.
Musk emphasized the strategic depth of the deal, noting that Tesla will directly assist in optimizing Samsung’s production process. He also hinted that the total value of the partnership could exceed the stated $16.5 billion. Samsung had initially indicated it would withhold details of the contract until 2033 to protect trade secrets, a measure agreed upon with the unnamed second party in the regulatory document.
Samsung’s stock responded positively to the announcement, rising over 6% and reaching its highest value since September 2024. The deal marks a major win for Samsung’s foundry division, which manufactures chips based on external designs and competes closely with Taiwan Semiconductor Manufacturing Company (TSMC), the world’s leading chip foundry.
The South Korean tech giant aims to start mass production of 2-nanometer chips, a cutting-edge process node that enhances performance and efficiency by enabling denser transistor layouts. This technology is crucial for powering AI workloads, and Samsung is vying for a stronger position in that market.
Samsung has been under pressure in the semiconductor space, particularly in its memory chip business. It has fallen behind rivals SK Hynix and Micron in high-bandwidth memory (HBM), a critical component in AI computing. SK Hynix currently leads this segment and supplies HBM chips to Nvidia, a dominant player in AI hardware. Reports suggest Samsung’s efforts to have its latest HBM version certified by Nvidia have been delayed until at least September.
The Tesla contract offers a significant boost to Samsung’s foundry operations at a time when weak demand and a shifting AI landscape have posed substantial challenges. The partnership could become a cornerstone of Samsung’s comeback in both logic and memory chip segments amid fierce industry competition.
