You might be able to find lists of offices for major tech companies via google maps. Off the top of my head:

Google, Facebook, Apple are all expanding to Seattle, some in multiple locations

Amazon is building an office in NoVa

Apple is building in Austin. Looks like Amazon, Apple, and Google are too

Google, Amazon, and Netflix are building in LA

I'm sure there are many more expansions occurring too, anyone may feel free to list more or correct me

Aren't these all regions that were destinations for SV "flight" 15 years ago as well?" I'm not saying the scale isn't different, but these statements could have been uttered awhile ago.

Sure, somewhat, and it's accelerating now.

What were the locations of small, nascent local software industries perhaps bootstrapped by some ancient incumbents are now becoming real hubs. The cycle will continue as the cities with small/no local software industries grow and those in turn become hubs. What's clear is that the more stable, hyper-profitable software companies are not expanding as much in the bay area as they used to

Google and apple coming to San Diego with decent sized offices. Lots of biotech investment here as well.
