Brands Urged to Prioritize Fans in Sports Marketing
Digiday reports that the sports marketing marketplace is accelerating as agencies and holding companies formalize sports-focused offerings, hire specialized talent and commission research on AI’s role in fandom. Horizon Sports & Experiences (HS&E) shared research — reviewed by Digiday — finding more than 75% of sports fans are aware of AI in sports, while only ~40% understand how it works; fans broadly accept AI when it augments stats, analytics or personalization but are wary when it appears autonomous or replaces human decision-making.

Stagwell has formalized its Sport Beach unit (named Beth Sidhu CEO) as a neutral platform to connect brands, athletes and rights holders, including activations at Cannes Lions featuring major athletes.
