Forecast rises 7.6 points on Sweden Democrats’ 2026 election outlook

The Sweden Democrats most-seats forecast moved from 14.5% to 22.1%, while supplied model estimates and Polymarket signals remain sharply divided.

The stored forecast alert published at 2026-08-25T08:54:20.572134+00:00 reported a rise of 7.6 points over 113 minutes, from 14.5% to 22.1%, for whether the Sweden Democrats (SD) will win the most seats in the 2026 Swedish parliamentary election. The movement is a live estimate rather than a settled election outcome.

The supplied AI Consensus run at 2026-08-25T08:50:59.954212+00:00 recorded a score of 0.4573, confidence of 0.4578 and dispersion of 0.33 across 3 judges. That run precedes the alert’s publication time, and the record provides no later update.

Supplied estimates disagree on the Sweden Democrats

google/gemini-2.5-flash-lite assigned the question a probability of 0.85 with confidence of 0.9. Its reasoning cited the September 13, 2026 election date, current polling and recent election trends in describing SD as a strong contender.

The other two supplied estimates were substantially lower. deepseek/deepseek-v4-flash assigned a probability of 0.15 with confidence of 0.75, saying SD faced strong competition from Social Democrats and Moderates. openai/gpt-4.1-nano also assigned 0.15, with confidence of 0.4, and said Sweden’s political dynamics remained competitive.

ai_gemini_flash_lite: “Current polling and recent election trends suggest SD is a strong contender to win the most seats, making a resolution by the deadline highly probable.”

Polymarket notes show a separate, lower set of signals

The five supplied Polymarket notes list market prices of 1.3%, 1.7%, 1.4%, 1.4% and 0.9%. Each is below both the alert’s earlier 14.5% position and its later 22.1% position.

No dates or times accompany those individual Polymarket signals, so the record does not establish whether they reflect the same moment as the forecast alert or the AI Consensus run. The different figures should therefore be read as separate supplied signals rather than interchangeable measures.

September 13, 2026 remains the decision point

The question’s supplied resolution date is 2026-09-13. The ai_gemini_flash_lite evidence also states that the election is scheduled for September 13, 2026, tying the forecast to the stated election date.

For readers following the race, the clearest new development is the move from 14.5% to 22.1%. The wider record remains divided, with estimates of 0.85 and 0.15 alongside much lower Polymarket notes, so the movement does not establish that SD will win the most seats.
