Sports sponsorship has emerged as a strategic branding tool that enhances brand equity through emotional engagement, visibility, cultural resonance, and associative symbolism with athletes, leagues, and mega-events. With globalization and digital media, sponsorship impacts brand perception across diverse markets, from football and Formula 1 to the Olympics and eSports. This paper synthesizes frameworks from brand equity theory, sports marketing, consumer psychology, and cross-cultural communication to propose the Global Sponsorship-to-Brand Equity Framework (GSBEF). The model explains how sponsorship activation influences brand awareness, perceived quality, loyalty, and brand associations across global audiences. The study concludes with strategic recommendations for multinational brands seeking to leverage sports partnerships.
