Sweden's next prime minister depends on a party polling 2%

Sweden votes on September 13, and Polymarket's next prime minister market has already reduced the country to 2 prices. Magdalena Andersson costs 85.5 cents, while Ulf Kristersson, the man currently doing the job, costs 11.5 cents. Everybody else on a board of nine named candidates costs under 3 cents.

Here's why we are buying Andersson's contract to capture 17%.

Sweden's parliament has a 4% threshold, and a party below it wins nothing at all. In 2022, the four Tidö parties took 176 seats against the left's 173, a majority of 3, and it existed only because Liberalerna scraped over at 4.61%.

Liberalerna is now polling at 2.0%. It needs about 266,000 votes and is on track for 160,000.

Nothing else has been close all year. Not one poll published in Sweden in 2026 has shown Tidö ahead. The poll of polls on July 31 had 53.5 against 45.1, seat projections run 182 to 202 against 147 to 167 in a chamber where 175 is a majority, and stripping Liberalerna out leaves the government bloc at 40 to 44.5. The tactical lending that used to rescue L is gone, because Moderaterna is now smaller than Sverigedemokraterna and has no votes to lend.

Which brings up the strangest number on the board. Jimmie Åkesson leads the largest party on the Swedish right and is priced at 1.7 cents, on $1,400,610 of volume, 9 times the favourite's. He opened at 9.5 cents in January and peaked at 12, then on April 1 he and Kristersson stood up together and announced that if Tidö wins, Kristersson is prime minister.

However, there are 2 important counterarguments here:

• Demoskop's August poll narrowed the bloc gap to 3.7 points, the smallest since autumn 2023, though L stayed at 2.4.
• The contract pays on somebody assuming office. Interim prime ministers do not count. The earliest confirmation vote is September 29, and in 2018 it took 134 days and 4 failed votes.
