Abstract
Caitlin Clark's emergence as a generational collegiate basketball talent triggered a profound shift in consumer behavior, known as the "Caitlin Clark Effect" (CCE; Lucas, 2025). This study examined attendance and venue utilization data from the University of Iowa's women's basketball program, spanning pre-, during-, and post-Clark periods. Results from one-way ANOVA analyses showed a statistically significant increase in average game attendance (home, away, and neutral), rising from 5,387 pre-Clark to 13,877 in her senior year (p < .001), with a sustained post-Clark average of 9,890. Arena capacity utilization followed a similar trajectory, increasing from 37.3% to 92.4%. Notably, post-Clark utilization remained at 74.3%, indicating durable fan interest. These findings provide time-sequenced evidence of a singular athlete catalyzing lasting institutional and market change in women's collegiate sports. The study advances sport business theory by illuminating the strategic implications of athlete-driven branding and challenges assumptions underpinning facility planning and resource allocation.
