He won his first podium in the next season in the third Stage World Cup in Ruka, Finland, on 26 November, in 15 km freestyle pursuit.

He won his first Olympic medal in sprint classical, losing only to Johannes Høsflot Klæbo and Federico Pellegrino.

In March, Bolshunov reached second place in a WC stage for the first time in his career in the 15 km classical event in Lahti.

Bolshunov led in the overall standings after fifteen stages until being replaced by Johannes Høsflot Klæbo during the Tour de Ski.

On 9 March, he won another stage in 50 km classical mass start in Holmenkollen, returning the yellow bib after Klæbo's poor performance there.
