Samsung Lands $16.5 Billion Tesla Chip Deal, Elon Musk Confirms AI6 Production in Texas
Custom 2nm AI chips for Tesla will be manufactured at Samsung’s underutilized Texas fab, with Elon Musk personally involved in oversight
If you’re still wondering whether Samsung Foundry is serious about getting out from under TSMC’s shadow, wonder no more. A decade-long, $16.5 billion deal just landed in its lap and the client isn’t some quiet startup from Shenzhen. It’s Tesla. And it’s personal.
On paper, the announcement was bland. A regulatory filing. No client name. Standard language about risk and non-disclosure. But then came Elon Musk, crashing the party with a post on X: confirming Tesla as the mystery buyer, detailing a custom AI chip design called AI6, and pointing a very specific finger at Samsung’s Taylor, Texas fab. That’s the one that’s been sitting idle, burning overhead, waiting for someone to bet big. That someone is him.
The $16.5 Billion Shot at Relevance
Let’s not sugarcoat this: Samsung’s foundry business has been bleeding. Losing over 4 trillion won (about $3 billion) in the first half of 2025 alone. Market share in the single digits. And for years, the same criticism: strong in memory, shaky in logic. Good at building chips for others, not so great at making them cutting-edge.
This deal with Tesla is a lifeline. A big, risky, high-stakes lifeline. The chip to be manufactured the AI6 isn’t just another piece of silicon. It’s the nerve center for Tesla’s full-stack AI ambitions, everything from self-driving to Dojo to in-car supercomputing.
And it’s all going to be made using 2-nanometer tech, the most advanced Samsung has ever put on the table. Frankly, no one thought they’d get a customer like Tesla this soon.
Musk Wants Control, Not Just Chips
Here’s where it gets interesting. Musk isn’t just buying chips. He’s buying proximity. “The fab is 30 minutes from my house,” he said, half joking, fully serious. He wants hands-on visibility. He’s demanded custom fabrication, meaning Samsung won’t just be printing someone else’s design; it’ll be building something Tesla-designed, Tesla-optimized, Tesla-obsessed.
He even said he’ll personally oversee efficiency improvements. Whether that’s hype or a real threat to fly in and shake up a foundry floor, no one’s quite sure. But knowing Musk, people believe it.
And he wasn’t done. He hinted that $16.5 billion might be just the floor, not the ceiling. If output scales, this thing could swell far past what Samsung disclosed.
Market Cheers. Investors Blink.
Samsung stock popped anywhere between 3.5% and 6%, depending who you ask. Not surprising. It’s the biggest intraday lift in weeks. Bloomberg Intelligence is already projecting 10% annual growth in Samsung’s foundry revenue because of it.
But in the background, you can hear the analysts whispering. Samsung’s track record in foundry? Spotty. Texas yields? Historically shaky. And let’s be real Tesla didn’t just fall into Samsung’s lap. This deal likely came with deep discounts and generous terms to pull them away from TSMC or Intel.
One Seoul-based investor put it bluntly: “It’s a win, yes. But it’s a win they had to bleed for.”
It’s About Texas. And Seoul. And the White House.
This isn’t just a tech deal. It’s geopolitical leverage. South Korea’s been nudging its champions to forge deeper U.S. ties, angling for tariff relief and Washington goodwill. Samsung putting $16.5 billion worth of production on U.S. soil? That’s music to Biden’s ears.
And for Tesla, it’s more than convenience. It’s insulation from supply chain risk, from cross-border tension, from depending too heavily on Taiwan. Having a major chip line domestically situated is a hedge Musk can live with.
Foundry or Folly?
Here’s the question that’ll hang over this deal for the next 12 to 24 months: Can Samsung deliver? Not “Can it produce chips?” of course it can. But can it deliver at scale, at yield, with the reliability Musk demands?
TSMC didn’t build its empire overnight. It took decades of trust and brutal discipline. Samsung’s just now getting serious. This deal is either the start of its foundry comeback or the last hurrah of a business that’s burned billions trying to matter.
Tesla’s betting it can trust Samsung to build the next brain of its AI machines. Samsung’s betting this is the customer that will finally make its foundry business more than just a headline.
Time will tell if this is strategy. Or survival.
