This new Amazon hub will go to whatever Government(s) offers the biggest subsidy package. Amazon's approach to peddle this out there in the public is disgusting as you are going have many cities burn through hundreds of thousands if not millions of dollars in putting due diligence and bid packages with consultants to try and lure Amazon to their back yard.

To figure out where Amazon will go just narrow down the list to Governments that would be willing to sell out billions in subsidies to Amazon. Large players like Dallas and Atlanta don't need Amazon as much as many would think, a starving city like Detroit with a emboldened Star Government though could easily roll out an extensive subsidy package to lure Amazon. By default, a Detroit Amazon hub would have spillover into Windsor which would benefit indirectly.

In Canada, Ontario would happily roll out subsidies as they have done similar to Oracle for example, providing a seven figure subsidy per employee to lure Oracle to produce a major employment hub here in the Province.

Montreal is a non starter with the French - Americans don't understand it (Quebec French Laws), and won't want to learn to understand it. You just need one ignorant Amazon executive to not understand why they speak both languages in Montreal but can only do business in French.

My bet is some place rust belt. Bezos personally has an obsession with replacing old industry and no better way to do that then planting a flat in the middle of America's former economic heart. Plus many of those Governments in the region would be willing to sell there souls and future generations for Amazon to come set up shop.

So likely ...

Detroit
Rust Belt (Pittsburgh)
California

-Wild Cards-
North Carolina
Toronto

-Long Shots-
Vegas
Arizona

Edit...

Folks are humming that Toronto has a shot as a way for Bezos to stick it to Trump as Canada will have more favorable migrant worker laws than the USA will in the near future. The political fallout on both sides wouldn't be pretty though as I am sure the WH would try to ding Amazon for relocating so many jobs outside of the USA.
