Children's Mercy Park

Originally, Sporting Club, the team's ownership group, planned to move to southeast Kansas City, Missouri on land previously occupied by Bannister Mall. The redevelopment plan, called The Trails, was passed on December 13, 2007.[11] The last package of economic incentives, a $30-million tax rebate, was passed on November 21, 2008.

The stadium's planned site had been demolished to prepare the site for infrastructure. It was intended to open in 2011 with a capacity of 18,500 seats. However, fallout from the 2008–2009 financial crisis placed the project on hiatus, and the stadium developer eventually sought to move the new project near the Village West retail center in Kansas City, Kansas, near the Kansas Speedway and CommunityAmerica Ballpark. The developer of The Trails complex sought additional borrowing authority from Kansas City, Missouri, to finance the building of the soccer stadium and its associated amateur soccer complex. However, the city was unwilling to provide the desired financing, leading the developer to seek a new site across the state line.[12]

Dave Matthews and Tim Reynolds performed at Farm Aid at Sporting Park on August 13, 2011.

In September 2009, the developer asked Wyandotte County and Kansas state officials for permission to use revenues from existing tax increment financing in the Village West area to help finance the soccer complex.[13] On December 17, Sporting KC president, Robb Heineman provided an update on the stadium situation published on team official website and blog,[14][15] basically putting the Kansas City, Kansas location as final, pending the signature of the final agreements. On December 21, construction machinery was already on the Legends site waiting to break ground on the site.[16][17] On January 19, Wyandotte County approved the bonds to help finance the stadium,[18] and on January 20, the groundbreaking ceremony happened with Sporting's CEO, Robb Heineman, using heavy machinery to move dirt on the construction site.[19]

The opening match took place on June 9, 2011, as Sporting played the Chicago Fire to a scoreless draw in front of an over-capacity crowd of 19,925.[20] The first goal would come days later during the 2011 CONCACAF Gold Cup when Dwayne De Rosario converted a penalty kick for Canada against Panama. Sporting's first goal came from C. J. Sapong in a 1–0 win over the San Jose Earthquakes, the club's first victory in the stadium. Sporting would finish its first regular season in the stadium with a 9–2–6 record at home. Average attendance was 17,810 for the year or 96.4% of capacity.

In the stadium's second season, Sporting KC averaged an attendance of 19,404, 105% of its capacity. That year, Sporting KC made it to the playoffs but lost to the Houston Dynamo in the conference semifinals, and won the US Open Cup by defeating the Seattle Sounders.

In 2013, Sporting KC once again raised their average attendance. Because of their 2012 US Open Cup win, they qualified for the CONCACAF Champions League, and played games both in the MLS and in CONCACAF. Children's Mercy Park also hosted to a World Cup qualifying match between the United States and Jamaica with an attendance of 18,467, where the United States shut out Jamaica 2–0, and the 2013 MLS All-Star Game between A.S. Roma and the MLS All-Stars with an attendance of 21,175, where A.S. Roma beat the All-Stars 3–1. Sporting KC set an attendance record of 21,650 in the playoffs when they defeated the Houston Dynamo 2–1 to advance to the MLS Cup Finals against Real Salt Lake, Sporting won in penalty kicks, the second final in two years to be hosted at Children's Mercy Park.

Also in 2013, it was announced that the 2014 through 2018 NCAA Division II Football Championships would be played at Children's Mercy Park, moving from Braly Municipal Stadium in Florence, Alabama. It was also announced that the 2015 NCAA College Cup would be played at Children's Mercy Park.[21][22]

In 2015, the stadium hosted FC Kansas City's home opener against fellow NWSL side Sky Blue FC.[23][24] The stadium also hosted two FC Kansas City matches in 2016, once again serving as the team's secondary stadium.[25][26]

The stadium announced in 2016 that they are adding a Skycam, as well as robo-cams behind the goals and on top of the stadium.[27][28][29]

During a CONCACAF Champions League match against Deportivo Toluca F.C. on February 21, 2019, a metal railing overlooking the southwest tunnel broke and caused several fans to fall. Toluca winger Felipe Pardo was injured with a toe fracture because of the railing.[30][31]
