23XI Racing has signed Corey Heim to a full-time NASCAR Cup Series ride beginning in 2027. Heim moves up from his role as a development driver, stepping into the seat vacated by Riley Herbst. The promotion marks a significant step for Heim, who has spent time developing his skills within the 23XI organization before earning this opportunity.
Heim becomes the latest prospect to graduate from 23XI's driver development pipeline into full-time competition at NASCAR's top level. The team, co-owned by Michael Jordan and Denny Hamlin, has demonstrated a commitment to nurturing young talent while maintaining competitive competence in the Cup Series. This strategy reflects how modern NASCAR teams balance the immediate demands of winning with long-term roster building.
