Marchbanks found his feet in the 250 class quickly, finishing in the top-ten overall in the first three rounds, which included a sixth place race finish at the opening round.

Marchbanks made his professional supercross debut in the 250SX West class of the 2019 AMA Supercross Championship, recording his first podium at the fifth round in San Diego, before ending the series in tenth. For the second year running, his outdoor season was impacted by the results of a crash at the fourth round, causing him to miss the following three events. Completing the remainder of the season, he finished fourteenth in the final standings.

During the COVID-19-impacted 2020 AMA Supercross Championship, Marchbanks competed in the 250SX East class. After strong results in the first three rounds, before taking his first professional win at the fourth round, held at the historic Daytona venue. Once the series returned from a pandemic-enforced break, Marchbanks took a podium at the first of the Salt Lake City events but would then injure his knee two rounds later. Despite missing the final two rounds, Marchbanks would end the championship in fourth.

ClubMX Yamaha

Following his injury, Marchbanks was informed he would not be retained by the Pro Circuit Kawasaki team and after a period on the sidelines, signed for the ClubMX Yamaha team for 2021. Returning to the 250SX West class, he started the 2021 AMA Supercross Championship with a podium finish at the opening round. After showing consistency over the following rounds, he finished sixth in the final standings. In the following outdoor season, Marchbanks started strongly with three top-ten overall finishes at the opening three rounds. After his form took a downturn in the second half of the season, he was diagnosed with Addison's disease, missing the final three rounds. The 2022 AMA Supercross Championship saw Marchbanks finish eighth in the final standings of the 250SX West class, with three fourth places as his best results. Two years after his win at Daytona, he made his 450SX class debut in the event, held on a weekend when the 250SX West class was not competing. Following the supercross season, Marchbanks moved up to a 450 for the full 2022 AMA National Motocross Championship, finishing twelfth in the final standings with a best overall result of ninth.

The recovery period from a pre-season wrist injury caused Marchbanks to miss the full 2023 AMA Supercross Championship. Returning for the 2023 AMA National Motocross Championship, Marchbanks started the season in the 250 class but from round three onwards returned to the 450 class he had competed in the previous season. This move saw him finish every race inside the top-ten, with a second place behind Jett Lawrence in the first race at the fourth round being his first outdoor top-three finish. His consistency on the 450 would see him finish sixth in the final standings. Marchbanks carried strong form into the 2024 AMA Supercross Championship, scoring two podiums in San Francisco and San Diego. Later in the season, at the Nashville round, he sustained a concussion and broken thumb during his heat race which forced him out of the remaining two rounds.
