$20 billion for a new fab is a lot of money, even to Apple.

Closer to $40b for a new fab for an established company to do it all correctly. It's a much more major investment to open a fab without ever doing it before, then continually use the brain power/institutional knowledge you've built up to stay near the forefront of fab tech, and then basically have weird incentives to build a foundry for only your products rather than the world at large.

You're setting yourself up for making a huge part of your future revenue stream being set aside for ongoing chipfab capex and research engineering. And that's a huge gamble, since getting this all setup is not guaranteed to succeed.

Is that true? I guess what I mean is, is it $40B if you are trying to replicate the scale of a TSMC fab? Or could you do it for considerably less if the fab is initially designed to the needs of single customer (Apple)?

Closer to $40B for some of the latest fabs from TSMC you're seeing, yes. While there could be huge simplification in SoC and packaging processes if it was focused on a single product, Apple's needs will likely still be about having cutting edge processors, so it would still be pretty high even if they were to just buy TSMC.

If it were only 20B then Apple would jump at the chance.

As would almost innumerable others.

Well, if the future of your company depends on a fab, twice $20B is cheap.
