11. Citi Field â New York Mets 2009, $922 Million
Opening in 2009, the Mets gorgeous ballpark really set a benchmark for what modern stadiums should cost. The only thing missing was a good baseball team for the fans to watch. It took New York a few years, but the Metropolitans finally returned to the postseason in 2015, powering their way to the World Series.
10. US Bank Stadium â Minnesota Vikings 2016, $1 Billion
The future home of the Vikings isn’t coming with a bargain basement price tag. After having the roof collapse at their previous stadium, Minnesota is going all out to ensure the safety and comfort of its fans.
