Elon Musk''s ''Texas Declaration''
In the AI Era, Samsung''s Name Has Appeared Again.

On July 28, 2025, Elon Musk announced via X (formerly Twitter) that "Samsung''s large new fab in Texas will become the dedicated factory for Tesla''s next-generation AI6 chip." He emphasized the decision''s weight by noting "its strategic importance is difficult to fully express in words."

Samsung currently produces Tesla''s AI4 chip, while TSMC handles AI5. AI5 will first be produced in Taiwan and later transferred to TSMC''s Arizona fab. AI6, however, will be produced from the outset at Samsung''s US fab with a dedicated process — which makes it different in significance. For Tesla, this represents completing a strategic choice about where and how to produce chips for autonomous vehicles, robotaxis, and AI robot "Optimus." For Samsung, securing a Tesla-dedicated line at its US foundry means establishing clear presence in AI semiconductor competition.

Why does TSMC handle AI5 while Samsung gets AI6? This is interpreted as Tesla''s dual strategy of diversifying its supply chain while utilizing both companies as strategic partners. TSMC stably handles initial chip production based on proven mass production capability and technology; Samsung proposes a customized foundry model providing US domestic production base and dedicated fab. The core of this announcement is "US domestic production" — against the backdrop of TSMC''s process miniaturization advantage requiring initial production in Taiwan, Samsung has dedicated its newest factory being built in Texas to Tesla''s AI6 chip production. This aligns with the US government''s semiconductor self-reliance strategy. For Samsung, this contract means more than performance — AI semiconductors for autonomous driving, robotics, and supercomputing are the fastest-growing sector over the next decade, and customized US production for core customer chips means securing "premium competitiveness in the AI foundry market." Elon Musk''s brief SNS post may be the signal that Samsung has stepped forward again toward the center of AI semiconductor hegemony.
