No, Disney does not own SeaWorld, and they are actually fierce competitors in the "themed entertainment" market. SeaWorld is owned by United Parks & Resorts Inc. (formerly SeaWorld Entertainment), which is a publicly traded company. Its largest shareholder in 2026 is Hill Path Capital, which owns roughly one-third of the company. Unlike Disney, which is a massive media conglomerate, SeaWorld is currently a "stand-alone" entity without a parent company to provide external capital, leading to its strategy of building high-intensity roller coasters to attract thrill-seekers. While the parks are located near each other in Orlando, they operate on entirely different business models, with SeaWorld increasingly shifting its focus from animal shows to record-breaking amusement park rides.
