He was involved in an altercation with Asbjørn Kragh Andersen at the Tour du Poitou-Charentes, with both riders being penalised one minute in the general classification and fined 200 Swiss francs.

Laporte started the 2021 season with a block of racing in France, which included a stage win and the points classification at the Étoile de Bessèges.

[48][49] He finished second at Dwars door Vlaanderen, leading home the peloton behind solo winner Dylan van Baarle,[50] and it was not until May and the Circuit de Wallonie for Laporte to take his second win of the season.

[57] Having taken an eighth-place finish in his first start at Kuurne–Brussels–Kuurne,[58] Laporte took his first victory for the team – and his first win at UCI World Tour level[58] – on the opening stage of Paris–Nice; Laporte capitalised on the tempo set by teammate Nathan Van Hooydonck on the Côte de Breuil-Bois-Robert, bringing Wout van Aert and Primož Roglič with him and the Team Jumbo–Visma trio worked together to hold off the peloton on the final 6 kilometres (3.7 miles) into Mantes-la-Ville.

[62] With Van Aert testing positive for COVID-19 prior to the Tour of Flanders, Laporte was one of the team's joint-leaders along with Tiesj Benoot,[63] and ultimately finished in ninth place.

[72] Laporte then won Dwars door Vlaanderen after a late solo attack from the lead group that he had bridged to a couple of kilometres earlier.

[75] In his final start in preparation for the Tour de France, Laporte took the opening stage of the Critérium du Dauphiné after catching Rune Herregodts, the sole remaining breakaway rider, just before the line in Chambon-sur-Lac.

[77] He would ultimately cede the jersey following the fourth stage, an individual time trial, but held onto the points classification lead for the remainder of the race.

[87][88][89] For his performances in 2023, Laporte was the winner of the Vélo d'Or français as the best French road rider of the season and received the Trophée Bernard Hinault in October.

[92] Laporte was drafted into Visma–Lease a Bike's Giro d'Italia team – to make his first start at the race – working as a lead-out rider for Olav Kooij, following injuries suffered by Wout van Aert during the spring classics.
