Amazon just revealed the top 20 contenders for its new headquarters — here are their incredible proposals (AMZN)

Amazon has waded through 238 proposals from cities across North America that are eager to become the home of its new headquarters, HQ2.

On Thursday, the company announced that it has reduced the list to 20 finalists, which includes Atlanta, Dallas, Washington, DC, and New York City.

In the next few months, Amazon will be working with these locations to investigate the bids in more detail before making a decision. Late last year, the company outlined several requirements for cities, including access to an international airport, a population of more than one million, and a "stable and business-friendly environment."

For the new headquarters, Amazon said it plans to invest over $5 billion and accommodate as many as 50,000 high-paying jobs, making it one of the largest corporate-civic giveaways in modern American history.
