DraftKings has filed a trademark application to gain exclusive rights to use the term "March Madness" in connection with its sports betting and promotional activities. The filing, made in March 2026 with the U.S. Patent and Trademark Office, aims to secure branding control for DraftKings during the high-profile NCAA college basketball tournament period. "March Madness" is widely recognized as the nickname for the annual NCAA basketball championships but DraftKings intends to leverage this well-known phrase to strengthen its marketing and customer engagement within the sports betting and fantasy sports sectors. The trademark move underscores the increasing competition among betting operators to claim key thematic trademarks related to major sports events. This development holds significance for the gambling and marketing industries within the United States, where DraftKings operates under evolving regulatory frameworks. The effort by DraftKings to trademark "March Madness" reflects the growing crossover between sports, gaming, and brand strategy in the expanding legal sports betting market.
