The September 27, 2026, French Senate elections, which renewed 178 seats through indirect voting by local officials, produced a net loss of two seats for the SER group, fixing its total at 62. Multiple tallies from departmental results and subsequent group affiliations confirmed this figure by early October, aligning precisely with trader consensus at 62-64 seats. The outcome reflected stable performance by SER incumbents in majoritarian contests alongside limited proportional gains, while broader shifts favored right-leaning and far-right lists at the expense of other left-leaning blocs. Minor adjustments from overseas results or final affiliations remain possible but are unlikely to shift the count outside the narrow band.
