Who is Haiden Deegan?
Haiden Deegan is an American professional motocross and supercross rider who competes for Monster Energy Yamaha Star Racing. He races under the number 38 and has built a reputation as one of the most aggressive, confident riders to come through the sport’s development pipeline in years.
Coming from a racing family gave him an early head start, but Deegan has more than backed it up with results. He is a two time AMA Supercross 250 West Champion (2025 and 2026), a two time AMA Pro Motocross 250 Champion, and has won the combined SuperMotocross World Championship in the 250 class multiple times since the format launched in 2023. For the 2026 season he stepped up to race a 450cc machine in Pro Motocross and the SMX Playoffs, a move widely seen as the start of his premier class career.
How old is Haiden Deegan? Age and birthday
Haiden Deegan was born on January 10, 2006, in Temecula, California. That makes him 20 years old as of 2026. He celebrates his birthday every January, right around the time the Monster Energy Supercross season kicks off, which means his birthday often lands close to the opening rounds at Anaheim.
His star sign is Capricorn, a detail fans often connect to his disciplined, no excuses approach to training and racing.
Haiden Deegan’s height, weight, and body measurements
Deegan stands at approximately 5 feet 7 inches (170 cm) tall and weighs around 150 pounds (68 kg). Some older articles list him slightly taller, closer to 5 feet 9 inches, but his most consistently reported measurement in recent profiles is 5’7″.
His build is fairly typical for a top level motocross athlete: lean, low body fat, and strong core and grip strength, all of which matter far more in this sport than raw height. Motocross demands endurance, quick reflexes, and the ability to control a 220+ pound bike through whoops, jumps, and rutted corners for 20 to 30 minutes at a time, so riders like Deegan train specifically for stamina and upper body control rather than bulk.
Education and early life
Haiden grew up in a household where motocross was not a hobby, it was the family business. His father Brian Deegan is a legendary freestyle motocross rider and founder of the Metal Mulisha brand, and his mother Marissa Deegan has managed much of the family’s racing and business operations.
Haiden started riding almost as soon as he could walk and was competing in organized amateur races by around age six. At age 10, while still riding for KTM, he landed a backflip on a 65cc bike, an early sign of the fearless style that would define his career. Like many elite young riders, Deegan balanced schooling with a demanding travel and training schedule, often relying on online or flexible education programs so he could compete in amateur nationals across the country.
His amateur résumé is one of the strongest of his generation. He won seven amateur national titles at Loretta Lynn’s Ranch, long considered the proving ground for future professional stars, and became one of the most heavily recruited amateur riders before turning pro.
Career
Amateur years
Before turning professional, Deegan spent years grinding through the amateur motocross circuit on KTM machinery. His seven Loretta Lynn’s amateur championships put him in rare company among young riders and made manufacturers take notice early. His combination of raw speed and showmanship, including that headline grabbing backflip at 10 years old, built his reputation long before he lined up in a professional gate.
In 2021, Deegan signed with Monster Energy Star Racing Yamaha, a move that set the stage for his professional career and gave him access to one of the most successful development programs in the sport.
Professional breakthrough
Deegan made his professional debut in the 250SX class at the 2023 Monster Energy AMA Supercross Championship, finishing fourth in just his fourth career start in Houston. He went on to earn three podium finishes that season and finished second overall in the final standings, which was enough to earn him the 2023 250SX Rookie of the Year award.
He carried that momentum into the 2023 AMA Pro Motocross season, picking up his first career overall win at the RedBud National and another at Washougal, finishing fourth overall for the year.
The 2024 season marked his true arrival as a title contender. Racing the 250SX East region, he claimed his first Supercross win in Arlington, Texas, added two more wins later in the year, and finished runner up in the championship behind Tom Vialle. That summer he dominated the AMA Pro Motocross 250 Championship with five overall wins, clinching his first outdoor title. He capped the year by winning the 2024 SMX World Championship in the 250 class, the second edition of the combined points format.
2025 and 2026 seasons
In 2025, Deegan switched to the 250SX West region and delivered a dominant campaign, clinching the championship at round 16 in Denver. He backed that up with another AMA Pro Motocross 250 title, giving him back to back outdoor championships and cementing his status as the class of the 250 field.
Ahead of 2026, Monster Energy Yamaha Star Racing signed Deegan to a multi year contract that outlined a clear plan: one more season on the 250 in Supercross, followed by a full move up to the 450cc class for Pro Motocross and the SMX Playoffs and Finals. He stuck to that plan, successfully defending his 250SX West title in dominant fashion at St. Louis, sealing the championship with two rounds still remaining and picking up his sixth combined Supercross, Motocross, and SMX title in the process.
Deegan then began his 450 class career at the opening round of Pro Motocross at Fox Raceway, racing directly against established 450 stars like Hunter Lawrence, Eli Tomac, and Jorge Prado. It marked the start of a new chapter as he transitions from 250 prodigy to a full time premier class contender.
What is Haiden Deegan’s net worth and salary?
Because Deegan is a private athlete and not a publicly traded company or celebrity with disclosed contracts, there is no single official figure for his net worth. Based on his factory racing contract, championship bonuses, sponsorship deals, and digital media income, most recent estimates place Haiden Deegan’s net worth somewhere between $3 million and $5 million as of 2026, with some estimates ranging as high as $6 million once long term sponsorship value is factored in.
His base salary from his Yamaha factory contract, combined with performance and championship bonuses, is estimated to fall between $500,000 and $1,000,000 per year, though exact figures are not publicly disclosed by the team.
Income sources
Haiden Deegan’s earnings come from several channels, not just race day paychecks:
- Factory racing contract: His multi year deal with Monster Energy Yamaha Star Racing is his primary and most stable income source.
- Race purses and championship bonuses: AMA Supercross and Motocross pay out prize money per event, with significant bonuses tied to winning championships and the SMX title.
- Sponsorships: Monster Energy, Fox Racing, and other motocross brands support him with endorsement deals separate from his team contract.
- Digital media and content: The Deegan family’s YouTube channel and Haiden’s own social platforms generate advertising and brand partnership revenue.
- Merchandise: Branded apparel and gear tied to his “DangerBoy” persona add another revenue stream.
Is Haiden Deegan dating anyone? Girlfriend and relationship status
Haiden Deegan has not publicly confirmed a girlfriend or relationship as of 2026. He keeps his personal life largely private and rarely discusses dating in interviews or on his official social media accounts.
That has not stopped speculation. Fans regularly circulate clips and comments on TikTok and Instagram trying to identify a potential partner, and various names have been floated by fan accounts over the past year. None of these claims have been confirmed by Deegan himself, so it is best to treat any specific name attached to him online as unverified rumor rather than fact. Given how competitive his 2026 racing schedule is between Supercross, Motocross, and his 450 transition, it is likely his personal life will stay out of the spotlight unless he chooses to share it.
Family background
Racing runs deep in the Deegan family, and it is a major part of why Haiden’s story resonates with fans of the sport.
- Brian Deegan (Father): A pioneering freestyle motocross rider, X Games medalist, and founder of the Metal Mulisha brand. Brian’s own racing background gave Haiden expert coaching from day one.
- Marissa Deegan (Mother): Plays an active role in managing the family’s racing and business affairs.
- Hailie Deegan (Sister): Haiden’s older sister is a well known NASCAR driver who competed in the ARCA Menards Series and NASCAR’s national touring series, making her one of the more recognizable young female drivers in American motorsports.
- Hudson Deegan (Brother): Known by the nickname “Huckson,” Hudson is the youngest Deegan sibling and races in the Supermini class, following the same amateur pathway Haiden once did.
The family’s shared motorsports background, documented heavily on their YouTube channel, has made the Deegans one of the most followed families in American racing culture.
Social media presence
Haiden Deegan has built a large following across social platforms, helped by both his race results and his outspoken, confident personality. He posts primarily under his “DangerBoy Deegan” persona on Instagram and TikTok, sharing training clips, race day content, and behind the scenes footage from the Monster Energy Yamaha Star Racing team.
The extended Deegan family also runs a shared YouTube channel documenting their lives on and off the track, which has become a key part of Haiden’s public profile beyond race results alone. His combined following across platforms sits well into the seven figures, making him one of the most recognized personalities in American motocross among younger fans.
