I think this might be the most reliable and most plugged in article that I’ve come across regarding Amazon’s second headquarters. It has Atlanta as the clear favorite for the location. I have always thought from the time Amazon made the announcement of a second headquarters that Atlanta had the best shot. Boston, Chicago, Philadelphia, and DC round out the top five. I think this clearly shows that Amazon is looking more east coast. Other cities of interest are Salt Lake City sitting at #14, Toronto at #12, Denver at #8, and Austin at #6. A dark horse that I think is slowly getting more attention is Pittsburgh which sits at #11.

Here is another article, this one is from Fortune as to why Atlanta is the early favorite. Salt Lake City isn’t mentioned or listed as a potential city. I think Delta having its largest hub in Atlanta will also be a main selling point. Delta’s CEO a couple weeks ago finally came out and said that Delta is watching the situation very closely and even though and can’t play favorites (because essentially all the Delta hub cities are all vying for the second headquarters; except Seattle of course), he thinks that Amazon would be a welcomed addition and a perfect fit in Atlanta.
