As of August 1, 2026, Prospect Card Radar does not have enough verified data to call Joseph Sullivan’s 1st Bowman Chrome auto overpriced or underpriced. His base 1st Bowman Chrome auto does not have an established card market yet, so there is no price percentile to compare his on-field performance against. What we can say: his bat ranks in the 28th percentile of 165 tracked prospect hitters (92 wRC+ over 343 plate appearances at Double-A), measured August 1, 2026. A verdict is published only once on-field percentiles and a price we can stand behind are both available, so this page will carry one as soon as that data lands.
