DraftKings has filed an application to trademark the term 'March Madness' for use in connection with sports betting and daily fantasy sports contests. The filing, submitted in early 2026, seeks protection for branding and promotional materials related to the popular college basketball tournament period known as March Madness. The NCAA has traditionally used the phrase extensively in its marketing and broadcasts but does not currently own an active trademark in all categories relevant to gaming and betting. DraftKings' move could complicate the usage rights of the term within the sports and gambling industries, potentially prompting legal challenges or licensing agreements. The development is notable as sports betting continues to grow in North America, and companies seek to secure exclusive marketing rights over widely recognized sports brands and phrases. The trademark application highlights the ongoing commercial importance of March Madness beyond the collegiate basketball event itself, extending into the rapidly evolving sports betting market.
