DraftKings-NCAA trademark fight exposes the commercial value of March Madness branding

DraftKings has formally responded to the NCAA’s trademark infringement lawsuit, setting up a high-stakes legal battle over some of the most valuable language in college sports. In a filing Wednesday in the Southern District of Indiana, the sportsbook argued that its use of terms such as “March Madness,” “Final Four,” “Elite Eight” and “Sweet Sixteen” is protected under the First Amendment and that the NCAA’s case will fail on the merits.

The NCAA filed suit last Friday, saying DraftKings infringed on federally registered marks by using tournament-related terms to promote its betting business. The association is seeking an emergency temporary restraining order to stop further use of those phrases, a move that signals how seriously it views the commercial and reputational risk around tournament branding.

At the center of the dispute is a broader business question: who controls the language that defines one of the most lucrative events on the sports calendar? DraftKings contends those phrases are widely understood shorthand for college basketball’s postseason and are used by fans, media outlets and the betting market to describe the tournament structure. The company also argued that it is not the only sportsbook using similar terminology and said the NCAA is selectively targeting its business.

The sportsbook’s defense goes beyond trademark law and into market reality. DraftKings said no single organization should be able to monopolize common terms that have become embedded in the sports ecosystem. It also challenged the NCAA’s request for emergency relief, calling the alleged urgency manufactured, while pointing to its partnership with Genius Sports, the NCAA’s official data distributor to sportsbooks through 2032.

The NCAA, however, has framed the lawsuit as part of a larger effort to preserve the separation between its championships and sports betting. In a statement Friday, the association said continued use of its marks creates the false impression that it has authorized or endorsed DraftKings’ platform, especially among college students and young adults who are viewed as more vulnerable to gambling harm.

That position reflects a growing tension across sports business: leagues and governing bodies are increasingly monetizing data, media rights and licensing, while simultaneously trying to limit the perception that betting operators can freely use the language and imagery that make those properties valuable. The NCAA says it has no commercial relationships with sportsbooks and maintains a strict ban on betting-related advertising and sponsorships.

The timing adds another layer of significance. The NCAA Tournament is moving into its second weekend, with Sweet Sixteen games and the Elite Eight about to take center stage. The association had sought a hearing before those games begin, underscoring the urgency of protecting trademark value during the most visible portion of the event.

The outcome could shape how sportsbooks market around major live events going forward, especially when the event itself has become a cultural and commercial shorthand with enormous consumer recognition. For the NCAA, the case is about protecting brand equity. For DraftKings and the broader betting market, it is about how far operators can go in using the language of sports to drive customer acquisition.
