Samantha Busch tugged at NASCAR’s heartstrings Monday with a touching birthday tribute to her son, Brexton, who turned 10 amid a weekend full of family celebrations and racing milestones. The Busch family’s social media posts, filled with clips from Brexton’s toddler days to trophy wins, marked a decade of both personal and professional triumphs.
Brexton’s journey—from miracle IVF baby to rising racing star—has reached far beyond the track.

Samantha’s post on X featured a video montage of Brexton’s racing highlights and sweet family memories.
“Happy 10th birthday to our incredible, talented, sweet boy! Brexton we love you so much!” she wrote.
The video showed Brexton’s growth—from a toddler covered in food to a focused young driver celebrating victories.

The milestone means a lot for the Busch family, who went through infertility before Brexton’s birth in 2015. Samantha and Kyle co-founded the Bundle of Joy Fund, which has given over $2 million to help other families with fertility treatments.
“Words cannot describe how your heart swells with immense love the second you see your child for the first time and get to hold him,” Samantha once said.
Kyle shared his own birthday message just hours later:
🎉 Happy 10th Birthday to my amazing son @brextonbusch! 🎉
I can hardly believe you’re already hitting this milestone—double digits, wow! You’re such a fantastic boy, a stellar racecar driver, an adventurous fisher/hunter, and the best brother and son anyone could hope for.… pic.twitter.com/Hh7HYt19uH

“Happy 10th Birthday to my amazing son @brextonbusch! I can hardly believe you’re already hitting this milestone — double digits, wow! … Your joy and personality brings happiness to all of us. I love you so much, and I can’t wait to celebrate you today!”
Brexton Busch Accelerates Toward Racing Stardom at 10
Brexton’s birthday isn’t just a big moment at home — it also kicks off a big step in his racing career. On May 22, he’ll make his INEX Legends National Qualifier debut at Hickory Motor Speedway, now eligible to race Legend Cars after turning 10.
“He can’t race a Legend Car until he turns 10. That’s this week,” Kyle told reporters earlier this month.
The young driver’s resume already impresses. With more than 100 wins in Bandoleros, outlaw karts, and junior sprint cars, Brexton also won the 2025 Jr. Sprint Championship at the Tulsa Shootout. Last season alone, he tallied 48 wins and 126 top-10 finishes.

Kyle has long had a plan for his son’s racing future. Back in 2022, he said:
“Brexton and I, we share a truck when he turns 16 years old, when he’s 16 and 17. And then it’s his when he’s 18. And I’m done. I’m out.”
The NASCAR world is taking notice.
“Only six more years until Brexton Busch can race on Truck Series short tracks and road courses,” journalist Jeff Gluck joked.
Uncle Kurt Busch, the 2004 Cup champ, added:
“Happy Birthday young man. Proud of you both on and off the track.”
For NASCAR fans, Brexton’s story is one of resilience and family legacy. From IVF miracle to karting standout, he’s following in his father’s footsteps. Samantha’s video is a reminder that some of life’s biggest wins happen far beyond the checkered flag.
