But I'm also sure that the whole Team Gresini will help me a lot," he added.
Marquez, who joined the Repsol Honda team in 2013, won the last of his six championships in 2019, finishing 151 points clear of his nearest rival.
He will join his brother Alex, who has impressed since he made the switch from LCR Honda to Gresini ahead of the 2023 season.
"This is a historical moment for the Gresini Family," Gresini boss Nadia Padovani Gresini said.
"The fact that Marc Marquez chose to race with us in the upcoming season is absolutely fantastic and I'm extremely happy to be able to make it official."
