Trader consensus favors CDU with a 40.5% implied probability of topping the September 20 Abgeordnetenhaus election, reflecting its narrow but consistent poll lead amid a four-way statistical tie. The latest Infratest dimap survey (April 23–27) shows CDU at 19%, edging Greens, Linke, and AfD at 18% each, with SPD at 14%—a tightening from earlier April INSA polls where CDU held 21%. Gains for Greens (+2 points) and AfD (+1) signal voter shifts, fueled by historically low approval for the CDU-SPD grand coalition and Mayor Kai Wegner. In Berlin's proportional representation system, CDU's incumbency as largest party and stronger coalition prospects (potentially with SPD or Greens) underpin its frontrunner status despite the competitive field.
