Carnival Cruise Line is owned by Carnival Corporation & plc, a dual-listed company that is the largest travel leisure company in the world. As of 2026, the company is publicly traded on both the New York Stock Exchange (CCL) and the London Stock Exchange (CUK). The Arison family, led by Micky Arison, remains the largest single shareholder and continues to exert significant influence over the company’s direction, with Micky Arison serving as the Chairman of the Board. Under this corporate umbrella, Carnival Corp owns nine distinct cruise brands, including Princess Cruises, Holland America Line, Seabourn, Cunard, and Costa Cruises. The day-to-day operations of the specific "Carnival Cruise Line" brand are led by President Christine Duffy. While the company is "owned" by its thousands of global shareholders, its identity is still deeply tied to the foundational legacy of Ted Arison, who started the company in 1972 with a single ship and a dream of "fun" for the masses.
