Elon Musk wants his own chip plant - not a small one, but one big enough to feed all his firms at once.
The plan is called Terafab. It would make chips for Tesla, xAI, SpaceX, and the rest of his empire.
But ASML's CEO just gave a warning of his own. Christophe Fouquet said this week that new fabs only work when ASML can keep up.
Translation: the snag might not be the chip plant. It could be the firm that makes the tools for it.
ASML makes the gear that prints the world's best chips. It's the only firm on Earth that does.
It builds EUV lithography machines - the tools used to print top AI chips, like the ones inside Nvidia's GPUs.
That makes ASML a quiet bottleneck for the whole AI boom. Every Nvidia chip and every TSMC wafer starts on a machine ASML shipped first.
Fouquet's words carry weight because his firm is already stretched. ASML's order list runs years deep, and each tool takes years to build and set up.
That puts a hard cap on how fast the AI buildout can grow. No new fab can run faster than ASML can ship the gear.

Musk pitched Terafab as one giant plant that could feed every firm he owns. That means Tesla, xAI, SpaceX, Starlink, and Optimus all from the same fab.
That's a huge ask. Tesla needs chips for self-driving cars and its Dojo computer, xAI races to build huge AI clusters, and Starlink and Optimus need chips too.
Musk's project would also join a long line. TSMC, Samsung, and Intel already take most of ASML's top orders.
Even so, ASML said earlier this month it would work with Musk on the project. Fouquet's note came a few weeks later: new fabs are great, as long as ASML can ship the tools on time.
The bottleneck for AI isn't just chip makers and fabs anymore. It's now the firms that make the gear that makes the chips.
Fouquet himself didn't say Terafab was in trouble. He just said new projects work when the supplier isn't tapped out.
That note is worth tracking. It comes from the one firm that picks who builds the top chips first.
So watch for two signs. Does ASML grow its output in the next few quarters, or do new fab plans start to slip?
Either move would tell investors who's getting served first in the AI race. The fabs near the front of ASML's line have a real edge.
