Tesla Awards Samsung $16.5B AI Chip Contract

Tesla CEO Elon Musk has turned to Samsung Electronics for the car maker’s next generation of artificial‑intelligence hardware. Musk disclosed on 28 July that Tesla and Samsung have signed a 10‑year chip supply agreement worth $16.5 billion. Under the deal, Samsung’s new fab in Taylor, Texas, will manufacture Tesla’s AI6 chips – the company’s successor to the AI5 that will power future iterations of its Full Self‑Driving system. Musk said on X that Tesla would help Samsung maximise manufacturing efficiency and hinted that actual orders could exceed $16.5 billion.

Why this matters

• Foundry shake‑up. Samsung’s foundry unit has struggled to compete with TSMC’s near‑monopoly; it holds just 8 % of the global market compared with TSMC’s 67 %. By landing Tesla – a prestige customer – the South Korean firm could reinvigorate its loss‑making business and attract other AI chip clients. Analysts estimate that Samsung’s foundry losses exceeded 5 trillion won (≈$3.6 billion) in the first half of 2025.

• Tesla’s chip roadmap. Samsung already makes Tesla’s AI4 chips (used in current FSD hardware) while TSMC will produce the AI5 starting later this year in Taiwan and eventually in Arizona. Musk has previously indicated that AI5 production will begin in late 2026 and hinted that AI6 chips would arrive after that. Analysts at SK Securities expect AI6 production to start in 2027 or 2028 but caution that Tesla often misses targets.

• Supply‑chain geopolitics. The order comes amid intensified trade negotiations between South Korea and the United States. Samsung had delayed the Taylor fab because it lacked major customers. Landing Tesla may provide political leverage as Seoul and Washington debate potential 25 % U.S. chip tariffs.

Samsung has long dominated memory chips but trails rivals in contract manufacturing. In 2021 it announced the $17 billion Taylor fab as part of a multibillion‑dollar push into logic chips. However, U.S. export controls on cutting‑edge lithography equipment and delayed orders forced the company to postpone the plant’s opening to 2026. Tesla, meanwhile, has increasingly custom‑designed its own chips for FSD, turning from GPU supplier Nvidia to in‑house silicon. The automaker is betting that vertical integration will give it an edge in self‑driving and robotics.

Samsung’s partnership with Tesla signals growing collaboration between automakers and chipmakers. With electric vehicles becoming rolling computers, controlling the supply of advanced AI silicon is critical. The success of this deal could influence where other automakers source their AI hardware. For consumers, it may accelerate the arrival of Tesla’s promised robotaxi service and safer driver‑assistance systems.
