Every year, the best builds and the boldest customizations face off in the industry's leading vehicle competition to see who will be crowned the next Battle of the Builders Presented by Mothers Polish champion.
Applications are open for the 2025 SEMA Battle of the Builders Presented by Mothers Polish at semabotb.com. All builders with a vehicle displayed at the 2025 SEMA Show may enter the competition at semabotb.com before the deadline on October 17, 2025.
The 2025 SEMA Battle of the Builders (BOTB) will recognize class champions as the best in four categories:
- Hot Rod & Hot Rod Truck
- 4 Wheel Drive & Off-Road
- Sport Compact, Import Performance, Luxury & Exotic
- Young Guns
Only one of the class champions will be crowned the overall BOTB champion during this year's SEMA Show, November 4-7, Las Vegas.
Battle of the Builders Young Guns Category
Supporting and inspiring young builders is crucial to the future of the automotive specialty-equipment market. The BOTB Young Guns category is designed to encourage young builders to pursue their passions and shine a light on the up-and-coming builders.
"Young Guns" is a designation within the overall BOTB competition to recognize builders who are under the age of 29 (as of November 7, 2025). Those who meet the criteria and have selected the Young Guns category on the online application are eligible to participate. In addition, all eligible Young Guns applicants who have submitted their online application before August 15, 2025, may be selected to compete in one or more virtual regional Golden Ticket competitions for the chance to win a Golden Ticket SEMA Show prize package. The eligible Young Guns applicants who have been selected for this will be contacted separately by the BOTB operations team via email or phone.
