Social media provides athletes with opportunities to enhance their personal brands, engage with fans, and access professional opportunities. Several studies have examined how athletes use social media to attract and engage large audiences. Less is known about the social forces that enable and constrain their popularity. Drawing on expectation states theory, this study considers how athletes’ social status affects their follower counts and engagement rates on Instagram. Based on a content analysis of 6240 images posted on Instagram by 112 professional disc golfers, we show that the gender, sport dominance, and physical attractiveness of athletes affect their popularity, controlling for their strategic efforts to self-brand. These findings offer new insight into the ongoing debate over social media’s impact on long-standing inequalities in the media-sport industry.
