Magdalena Andersson leads trader consensus for Sweden’s next prime minister because her Social Democrats head the centre-left bloc that captured a narrow 176–173 seat majority in the September 2026 Riksdag election, positioning her as the designated candidate to form government. Ongoing exploratory talks with the Left, Green, and Centre parties continue into mid-October, with the speaker preparing a possible confidence vote. Ulf Kristersson’s lower odds reflect the right-wing bloc’s seat deficit and his resignation as prime minister after the result. A recent Novus survey showing Kristersson overtaking Andersson in personal trust ratings and Ebba Busch rising has not shifted the parliamentary math that underpins current pricing. Resolution hinges on successful coalition agreement or a failed vote that could reopen negotiations.
