HEY, BIG SPENDER: Intel Lands Musk’s $25 Billion Terafab: A Billion-Dollar Foundry Win in the Making?

Intel’s role centers on what it does best: design, fabrication, and packaging at scale. The company’s post explicitly ties its contribution to accelerating Terafab’s 1 TW per year target using its “ultra-high-performance chips.” In plain English, this isn’t Tesla or SpaceX building a rival fab from scratch. It’s an Intel Foundry expansion in Austin with Musk’s companies as anchor customers. That means Intel just landed a marquee, high-volume partner for its 18A and future nodes — exactly the kind of external validation the foundry has chased for years.

Let’s put the numbers in context. Intel’s full-year 2025 foundry revenue reached $17.8 billion, up 3% year-over-year. Q4 alone delivered $4.5 billion, also up 4%. Yet external customer revenue for the full year totaled just $307 million, including $222 million in Q4. The majority of the foundry’s business was internal production for Intel’s own CPUs. The unit still posted a $10.3 billion operating loss for 2025, driven by 18A ramp costs.

Terafab changes the math. A project of this scale could push external revenue into the billions annually once wafers start flowing.

We already know where SpaceX will get the cash: Musk’s SpaceX courts retail investors as it aims for record-breaking stock market flotation.
