Tesla and Nvidia Jointly Invest $2.8 Billion in Samsung Electro-Mechanics for AI Chip Substrate Production Line
nashnova research
Tesla and Nvidia plan to invest a combined $2.8 billion to build an advanced AI-chip substrate line for Samsung Electro-Mechanics in Sejong, South Korea — two of the largest AI-compute buyers locking in the same supplier signals that upstream packaging materials have become a bottleneck.
What exactly is this money funding?
The target is FC-BGA substrates — flip-chip ball-grid-array packages that serve as the "baseboard" connecting an AI chip to its circuit board, directly affecting performance and yield.
The production line will be built in Sejong City, South Korea, operated by Samsung Electro-Mechanics (Samsung SDI's sibling under Samsung Group).
This means → Nvidia and Tesla are not buying chips; they are securing the packaging material required before chips can even be assembled.
How much is each side putting in, and how is it structured?
Nvidia commits roughly KRW 2.6 trillion (~$1.9 bn), about 70 % of the total; Tesla commits roughly KRW 1.1 trillion (~$0.8 bn).
Both invest through long-term supply contracts, not equity stakes — Samsung Electro-Mechanics gets guaranteed orders, not new shareholders.
In plain terms = "I'll help you build the factory; your output for the next several years is mine."
Why are Nvidia and Tesla getting involved directly?
FC-BGA is the critical bottleneck material in high-end GPU and AI-accelerator packaging; global capacity sits with only a handful of suppliers.
Nvidia's AI-chip shipments keep surging; Tesla's autonomous-driving stack and Dojo supercomputer are equally power-hungry — both need stable, sufficient substrate supply.
This reflects a shift: the AI-compute race has moved from "who designs the strongest chip" to "who can lock in upstream materials."
Has this been officially confirmed?
The report cites unnamed industry sources and was published by China's National Business Daily (每日经济新闻).
None of the three parties — Tesla, Nvidia, or Samsung Electro-Mechanics — has publicly confirmed the deal.
This means → investment amounts and contract terms could still change; official disclosure is pending.
