Sesame Workshop Sues United Parks to End Long-Running Theme Park License, Citing Royalties and Brand Dispute

A decades-long U.S. theme-park partnership moves into high-stakes litigation

Sesame Workshop, the nonprofit organization behind Sesame Street, has filed a federal lawsuit seeking to end its long-standing theme-park licensing relationship with United Parks & Resorts, the company that owns and operates SeaWorld and Busch Gardens properties. The case, filed March 12, 2026, asks the court to declare the agreement terminated and to award damages tied to the parties’ contract dispute.

The relationship has made Sesame Street characters a consistent presence in U.S. family entertainment beyond television, including through Sesame Place Philadelphia and character-branded areas and experiences at several parks operated by United Parks. The new lawsuit directly targets that commercial footprint, potentially reshaping where and how Sesame Street-branded attractions can operate in the United States.

What Sesame Workshop is asking the court to do

In its filing, Sesame Workshop seeks to end the contract governing United Parks’ rights to use Sesame Street intellectual property in its parks and related offerings. The lawsuit asserts that the operator withheld royalty payments and engaged in conduct that Sesame Workshop says harmed the value and integrity of the brand.

The complaint also describes an escalation in the business relationship that culminated in an alleged stoppage of royalty payments in 2025, which Sesame Workshop portrays as a central breach. Sesame Workshop additionally requests monetary relief; the specific amount is not stated in public summaries of the filing.

The lawsuit frames the conflict as both a payment dispute and a broader disagreement over brand stewardship in park settings.

How this lawsuit fits into earlier legal conflict between the parties

The new action follows a separate legal fight in Florida federal court connected to arbitration over licensing royalties. In that earlier matter, Sesame Workshop pursued confirmation of an arbitration award tied to royalty calculations and amounts owed under the parties’ licensing arrangements. Court records in the Middle District of Florida show extensive sealed filings, reflecting commercially sensitive contract details.

That arbitration-related litigation underscored that the partnership, while long-running, has included complex revenue-sharing mechanics and performance obligations. The March 2026 lawsuit now appears to move beyond disputes over calculation and payment and into the question of whether the relationship should continue at all.

Operational implications for parks and visitors

The lawsuit does not itself remove Sesame Street branding from parks overnight. Termination, if granted, would likely trigger a transition period governed by contract terms and subsequent court orders, potentially affecting:

• Sesame Street-branded lands and character experiences at SeaWorld and Busch Gardens parks
• Merchandise, food-and-beverage tie-ins, and licensed events that use Sesame Street elements
• Marketing, signage, and entertainment programming that depends on the licensed characters

United Parks has not, in publicly available summaries, conceded wrongdoing. The case is expected to proceed through motions and scheduling typical of federal litigation, with the court assessing the contract’s termination provisions and the evidence supporting alleged breaches.
