Intel 18A for Stargate CPUs?

So, Stargate announced with $100Bn now and $500Bn over 4 years from SoftBank.

The technology partners are Nvidia & ARM + Oracle.

Makes sense that SoftBank is funding ARM based CPUs for the project.

What do people think about the possibility of the CPUs being custom Microsoft ARM chips fabbed on Intel 18A - supporting the “re-industrialisation” of America?
