Lars Markus Hildingsson leads the market at 75.5% as the Social Democrats’ top candidate for Region Blekinge’s board chair following the September 13, 2026, regional election. Traders have shifted heavily toward him amid SD’s reported mandate losses across Blekinge and the breakdown of the prior SD-M-KD cooperation, positioning S to lead coalition negotiations for the new regionstyrelse. Current chair Björn Tenland Nurhadi (SD) sits at just 5.5%, reflecting the governing bloc’s weakened position after recent turbulence and leadership transitions. Lower-probability names such as Hanna Ekblad and others at or below 15% capture residual uncertainty over final coalition partners, committee placements, and any late list adjustments before the regionfullmäktige formally selects the chair. The implied probabilities mirror the post-election consensus on S’s strengthened bargaining position in the weeks ahead.
