Worlds of Fun · KS.City

Worlds of Fun is a major amusement park in Kansas City’s Northland that opened in 1973, developed by Lamar Hunt and Jack Steadman through their company Mid-America Enterprises. It has operated continuously since, passing to Cedar Fair in 1995 and, through subsequent corporate transactions, to new ownership in 2026. The adjacent Oceans of Fun water park opened in 1982.¹²

⚠ Correction, 2026-08-01: earlier versions of this page attributed the park’s development to a Hallmark Cards subsidiary. No source consulted supports that attribution; both Wikipedia and the Kansas City Public Library’s Missouri Valley Special Collections credit Lamar Hunt’s Mid-America Enterprises.¹² The Hallmark framing has been corrected throughout.(/wiki/industrial-history/hallmark-cards/) and any other page repeating the Hallmark/Worlds of Fun link]

Background

1973 Mid-America Enterprises development

Worlds of Fun was conceived and developed by Lamar Hunt — owner of the Kansas City Chiefs — and Jack Steadman, the Chiefs’ general manager, through Hunt’s company Mid-America Enterprises, which held real-estate, entertainment, and mining interests in Kansas City. Theme-park designer Randall Duell shaped the park’s layout.¹² Ground was broken on November 8, 1971 and the park opened on May 26, 1973, at a reported cost of roughly $20-20.5 million.¹²

At the opening, Hunt framed the project’s ambition: “Our idea is to create a fun and entertainment center with enough glamour and appeal to attract people from all over the United States to spend their vacation time and entertainment dollars in Kansas City.”¹

The development context included:

A broader American corporate pattern of destination amusement-park development in the 1960s and 1970s (including Disney and Six Flags)
Acquisition of substantial Northland acreage suitable for a large-scale themed park
Themed design modeled on Jules Verne’s Around the World in Eighty Days, with international-themed areas representing different continents and cultures²

On the Hallmark question: Hallmark Cards was a defining KC corporate presence in this period — Crown Center opened in 1971 — but no source consulted connects Hallmark to the ownership or development of Worlds of Fun, and Hallmark’s own corporate history does not claim it.⁴

1995 Cedar Fair sale

In 1995, Worlds of Fun (and the paired Oceans of Fun) was sold to Cedar Fair LP, an Ohio-based amusement-park operator, for a reported $40 million.² The sale:

Preserved operational continuity under Cedar Fair management
Enabled ongoing investment and additions to the park in subsequent decades

Later ownership

Cedar Fair merged with Six Flags Entertainment Corporation in 2024, bringing Worlds of Fun under the combined company.¹ Wikipedia further reports that Six Flags announced the sale of Worlds of Fun to EPR Properties on March 5, 2026, completed April 6, 2026, with operations passing to Enchanted Parks.²

Programming and features

Worlds of Fun features a variety of roller coasters, thrill rides, family rides, themed areas, and entertainment programming.⁵ The park maintains a mix of high-thrill attractions and family-friendly options across its themed zones.

The adjacent Oceans of Fun water park (opened 1982, and described at opening as the largest water park in the world) complements Worlds of Fun as a multi-park Northland amusement destination.²³

Long-term significance

Worlds of Fun has anchored KC’s amusement-park tradition for more than 50 years.⁶ It serves as a major Northland tourism and entertainment destination and stands as a notable example of Kansas City sports-and-real-estate capital — Lamar Hunt’s Mid-America Enterprises — building a national-scale leisure attraction in its home city.¹ Through the Cedar Fair and Six Flags eras it has been part of a national network of amusement parks.
