Venezia and Frosinone earned automatic promotion to Serie A by topping the 2025-26 Serie B table with 82 and 81 points. Venezia sealed the title with strong defensive displays and efficient attacking output across 38 matches, while Frosinone clinched second place through a late surge that included decisive victories over direct rivals. The third promotion spot was decided via playoffs among third-placed Monza, fourth-placed Palermo, and lower seeds such as Catanzaro and Juve Stabia, where aggregate results, home advantage, and squad depth ultimately favored Cremonese in the final. Recent form, goal difference, and fixture congestion shaped the final standings and playoff outcomes.
