In 2022, the Royals announced intentions to build and open a new stadium before the team's lease agreement with Jackson County expires at the end of the 2030 MLB season.

In April 2024, Jackson County voters overwhelmingly rejected a ballot initiative to help fund the new stadium by a 16% margin.

The proposal of the Truman Sports Complex was unusual, as conventional wisdom at the time held that separate football and baseball stadiums were not commercially viable.

[12] After the move, Senator Stuart Symington of Missouri threatened to press for the revocation of baseball's anti-trust exemption if they did not give Kansas City a new team.

However, Symington forced MLB to move up the start date to 1969 as he was unwilling to have Kansas City wait three years to have baseball again.

The other expansion team in the American League, the Seattle Pilots, were without a suitable stadium in 1969 and the accelerated schedule forced by Symington led to their bankruptcy after just one season.

[13] Royals Stadium broke ground on July 11, 1968, and was opened in on April 10, 1973, with a 12–1 win over the Texas Rangers that saw 39,464 fans in attendance.

[12][14][15] Five weeks later, Nolan Ryan of the California Angels threw the first of his seven no-hitters, blanking the Royals 3–0, three walks away from a perfect game.

[12] Following the 1976 regular season, the Royals competed in the first postseason game of their history on October 9, but lost 4–1 at home to the New York Yankees in the ALCS.

In 2020, Kansas City-based design firm Populous unveiled a concept for a potential new downtown baseball stadium, showing an intimate facility with unique amenities.

[23] In November 2022, team owner John Sherman announced the franchise's controversial intention to leave Kauffman Stadium before the lease ends after the 2030 MLB season,[8] with intentions of building a new stadium in downtown Kansas City (East Village) or North Kansas City.

The plan was a controversial one, Considering the proposed stadium location would displace over a dozen small businesses, the limited amount of parking downtown, and claims that Kauffman got a “bad batch of concrete” when built.

[9] The Royals had pledged to invest at least $1 billion towards purchasing and developing land around the stadium, but was only willing to put $300 million towards a new ballpark.

[25] On June 8, 2024, Sam Mellinger, the Royals' vice president of communications, said that the team is evaluating "all options that may be available with respect to a new stadium," and pointed to the Kansas Legislature's upcoming vote to make changes to the state's Sales Tax and Revenue (STAR) bonds program to attract major sports teams to the state.

[26] In August 2024, The Kansas City Star reported that the Royals were considering a new site for a downtown ballpark in Washington State Park, an area located between Union Station and Crown Center.

[30] Before the Colorado Rockies expansion franchise began play in Denver, Colorado, in the 1993 Major League Baseball season, the Royals' "home" territory included the Rocky Mountains in addition to a large swath of the Great Plains, and Kauffman didn't want fans who drove many hundreds of miles to go home without seeing games completed.

As part of the project, four-inch (10 cm) perforated tiles were installed at 12.5-foot (3.8 m) centers across the entire field in order to improve drainage.

Prior to the 1991 season, a Sony Jumbotron full-color video board was installed beyond the left field wall.

On April 4, 2006, Jackson County voters approved a 0.375% sales tax increase to fund plans to renovate the Truman Sports Complex.

As part of this measure, every Jackson County residential address was to receive vouchers good for 50% off two tickets at Royals games on certain nights.

[35] The display was assembled in 55 separate segments, including an active bottom taper to resemble the shield in the Royals logo.

The video scoreboard alone cost $8.3 million, and the control room that operates it is staffed with 17 people on game days.
