The final numbers are in, and thanks to the incredible generosity of our buyers, businesses, families, and community supporters, the 2026 Contra Costa County Fair Junior Livestock Auction reached a record-breaking $838,715.53!🦁🎉

This milestone represents more than dollars raised—it reflects countless early mornings, late nights, dedication, responsibility, and hard work from our youth exhibitors. Every bid, add-on, and purchase was an investment in the next generation of agricultural leaders.

From the auction ring to the barn, the support shown this year was truly extraordinary. Thank you to everyone who raised a paddle, wrote an add-on, volunteered their time, or cheered on our exhibitors. Together, we didn’t just break a record—we made fair history. 👏🏻

Now THAT’S something to go WILD about!

Our office will be closed today, June 2.
