After more than a year of aggressive competition, bets and speculation, the arms race for Amazon's second headquarters is reportedly over. New York City and Arlington, Virginia, will each get half of Amazon's promised second headquarters.

The e-commerce behemoth selected the neighborhoods of Long Island City in Queens and Crystal City in Arlington, Virginia, the Wall Street Journal first reported. The Washington Post, owned by Amazon CEO Jeff Bezos, also reports the decision is final.

The two locations sit across rivers from the centers of American financial and political power, respectively. The headquarters project, initially promised to house 50,000 tech employees and involve an estimated $5B investment as "a full equal" to its Seattle campus, will be half that. Amazon ultimately decided to mitigate the impacts its unprecedented economic development project would have.

In choosing the metropolitan areas of New York City and Washington, D.C., Amazon selected the two markets with more tech workers than any other city in the U.S., according to Cushman & Wakefield. If split evenly from Amazon's original commitment, Amazon would occupy 4M SF in each area and invest over $2.5B over the next decade or more. By the end of 2019, it would open 250K SF offices in each city, according to reports.
