About a month ago, Chicago began to buzz with the possibility of landing Amazon’s secondary headquarters outside of Seattle. Now, the Chicago Tribune reports that Mayor Rahm Emanuel and Governor Bruce Rauner announced that the city and state electronically submitted a proposal to the e-commerce company.

Chicago and Illinois’s bid was submitted on the first day Amazon was accepting proposals from cities across North America, according to the report. 

The details of what financial incentives and sites were included in the bid have yet to be released, but there are a number of Chicago sites and suburbs that potentially made the cut. The Lincoln Yards development located at the former A. Finkl & Sons Steel site, the former McDonald’s headquarters location in Oak Brook, and suburbs Orland Park and Tinley Park have all been floated as potential locations.

“This bid will demonstrate to Amazon that Chicago has the talent, transportation, and technology to help the company as it reaches new heights and continues to thrive for generations to come,” said Emanuel, according to the Chicago Tribune.
