Will SPD win the most seats in the 2026 Berlin state elections?

Prediction markets put the probability at 8%: Will SPD win the most seats in the 2026 Berlin state elections. Currently, markets see this as unlikely (8% YES). Berlin eyes bid around 1936 Games' centennial.

What’s Happening

The prediction market assessing whether the SPD will win the most seats in the 2026 Berlin state elections currently shows an 8% probability for the Social Democrats, reflecting deep skepticism about their ability to reclaim the top spot in the capital. This low confidence follows a series of recent political setbacks, including the party’s internal divisions over the city’s controversial bid to rehost the Olympic Games on or after the 100th anniversary of the 1936 Games. While Berlin’s state parliament approved the Olympic bid in May 2026, the SPD provided only conditional support, with some members openly opposing the plan championed by Mayor Kai Wegner’s CDU. The party’s fractured stance on a high-profile issue has eroded its standing among voters, who increasingly view the SPD as unable to present a unified vision for the city’s future.

The 92% NO probability also reflects broader electoral trends that have weakened the SPD’s traditional base in Berlin. Recent polling data from May 2026 shows the CDU leading with approximately 28% of the vote, while the SPD trails at 18%, a drop of nearly 3 points since the start of the year. The far-right AfD has surged to 17%, capitalizing on voter frustration over migration and housing costs, issues where the SPD’s coalition government has failed to deliver clear results. The party’s inability to secure the most seats in the Berlin state elections is further complicated by internal leadership disputes, as the current state chair, Franziska Giffey, faces criticism from left-wing factions for her pragmatic approach to coalition-building with the CDU.

Looking ahead, the SPD’s path to winning the most seats in the 2026 Berlin state elections hinges on several procedural and political milestones. The party must first survive a series of internal party votes scheduled for July 2026, where delegates will decide on a revised campaign platform that emphasizes social housing and climate action. Additionally, the SPD faces a critical test in the September 2026 Saxony-Anhalt state election, where a poor performance could further depress morale and fundraising for the Berlin campaign. The party’s best hope lies in a potential split among CDU and AfD voters, but with the CDU’s approval rating holding steady at 32% in Berlin, the SPD appears unlikely to close the gap before the October 2026 election date.
