Disney's Animal Kingdom cost approximately $1 billion to construct when it opened on April 22, 1998. Adjusted for inflation in 2026, that initial investment would be equivalent to roughly $1.9 billion to $2.1 billion. This massive budget covered the development of 500 acres of land, making it the largest Disney theme park in the world. Significant portions of the budget were dedicated to sophisticated animal care facilities, the complex "Kilimanjaro Safaris" landscape engineering, and the construction of the 14-story "Tree of Life." Since its opening, Disney has invested billions more into expansions, most notably the $500 million Pandora – The World of Avatar land which opened in 2017. In 2026, the park continues to see heavy investment as part of Disney’s broader $60 billion plan to expand its global parks and resorts division over the next decade.
