Samsung to manufacture Tesla's AI6 chips in $16.5B agreement

Tesla and Samsung have entered a landmark $16.5 billion agreement to manufacture Tesla's next-generation AI6 chips at Samsung's new fabrication facility in Taylor, Texas. This multiyear deal runs through 2033 and marks the largest contract ever for Samsung's foundry business.

The AI6 chips are poised to power Tesla's autonomous driving systems and potentially future robotics platforms. CEO Elon Musk emphasized the strategic importance of the deal and will personally oversee the efficiency of the production plant in Texas.

Tesla’s evolving semiconductor strategy

Tesla currently uses Samsung to produce its A14 chips and contracts with TSMC for its upcoming AI5 chips. The AI6 chips, expected to be Samsung's most advanced, will be manufactured using their cutting-edge 2-nanometer process technology.

This multi-vendor strategy leverages the strengths of each manufacturer, supporting Tesla's lead in electric vehicle autonomy while hedging supply risks.
