Brazilian presidential election 1st round (October 4, 2026): Luiz Inácio Lula da Silva (PT) advances to the run-off on October 25, 2026 (confirmed by Tribunal Superior Eleitoral by October 5, 2026)

Pending ✦ AI-generated prediction Published on 8. September 2026 · Predicted for 4. October 2026 · Based on: Historical Cycle

Probability

90%

Lula da Silva (80, PT) runs as incumbent for a fourth term. Current polls (AS/COA Poll Tracker, August 2026): Lula ~38%, Flávio Bolsonaro (PL) ~30%, Augusto Cury ~11%, rest <21%. An outright majority in the first round (>50%) is virtually impossible — since 2002, every Brazilian presidential election has gone to a run-off. Lula staying within the top 2 candidates and thus advancing to the run-off is considered near-certain: equivalent prediction markets place this at >88%. Complementary Cassandra forecast to the existing open prediction on Tarcísio de Freitas (Republicanos) also advancing to the run-off.

Berlin state election (20 September 2026): SPD receives more than 18.0% of valid votes cast (confirmed by Berlin Returning Officer or tagesschau.de by 21 September 2026)

The SPD received exactly 18.4% in the 2023 Berlin state election and has since been in opposition. Current polls (August/September 2026) put the SPD at 19–22%, making a result above 18.0% likely. Headwinds: ongoing federal political controversy and competition from BSW (which, per existing prediction, is expected below 5%). The 18.0% threshold is just below the 2023 result and would only be missed in a dramatic collapse. No Polymarket market; Metaculus aggregate implies ~65% for SPD above 18%.

Berlin Abgeordnetenhaus election (September 20, 2026): FDP falls below 5.0% of valid votes and fails to enter the Abgeordnetenhaus (confirmed by Berlin returning officer or tagesschau.de by September 21, 2026)

Both current Berlin polls place the FDP far below the 5% threshold: INSA (Sept 2–4, 2026): 3.0%; Infratest dimap (Aug 27–31, 2026): FDP below the statistical detectable threshold. The Berlin FDP has not reached the 5% mark in any poll since spring 2026. Clearing the hurdle would require a simultaneous systematic error of 2+ points from both institutes — historically near-unprecedented. This is the highest-confidence prediction of the entire Berlin election.

Swedish Riksdag election (September 13, 2026): Liberalerna (L) falls below 4.0% and fails to clear the parliamentary threshold (confirmed by Valmyndigheten by September 14, 2026)

Current polls show Liberalerna well below the 4% threshold: Indikator Opinion (fieldwork to September 4, 2026): 2.2%; PolitPro election trend (as of September 9, 2026): 2.7%. Neither institute identifies meaningful upward momentum. The party was part of the Tidö coalition but suffered from its image problems. Even with maximum systematic polling error of +1.5 points, Liberalerna would remain below 4.2%. Failing to enter the Riksdag would cost the governing coalition its parliamentary majority.
