DraftKings has applied for a trademark on the term "March Madness" in connection with online sports betting services, according to a filing submitted to the U.S. Patent and Trademark Office on February 28, 2026. The application specifically targets live and mobile sports betting related to college basketball tournaments, including the nationally prominent NCAA March Madness event. This strategic trademark pursuit could give DraftKings a competitive edge in branding and marketing rights during one of the biggest college sports betting seasons. The move highlights the growing importance of exclusive intellectual property rights in the increasingly crowded sports wagering marketplace in the United States. The outcome of this trademark application could impact how betting operators engage with fans and promote products linked to the iconic tournament.
