Predicted for 4. October 2026
·
Based on: Statistical Pattern
Latest poll: Datafolha (Sept 17, 2026) shows Lula at 39% vs Flávio Bolsonaro at 36% in the first round. Other surveys: Quaest (Aug 2026): Lula 38% vs Bolsonaro 31%; AtlasIntel (Sept 17): Lula 44.1% vs Bolsonaro 41.7%. Neither candidate will reach 50%+ outright; a runoff on October 25 is virtually certain. Polymarket gives Bolsonaro a 55.6% chance to win the overall election, but that market concerns the runoff winner, not first-round leader. Lula has historically finished first in every first round he contested (2002, 2006, 2022). Risk: late Bolsonaro mobilization, but closing a six-point gap in under two weeks is very unlikely.
Data basis for this prediction
- Datafolha (17.9.2026): Lula 39 % vs. Bolsonaro 36 % (1. Wahlgang)
- AtlasIntel/Bloomberg (17.9.2026): Lula 44,1 % vs. Bolsonaro 41,7 % (1. Wahlgang)
- Polymarket: Bolsonaro gewinnt Gesamtwahl 55,6 % (18.9.2026)

All current polls place CDU consistently at 20%: INSA (18 Sept) 20%, FG Wahlen/ZDF (17 Sept) 20%, Infratest dimap/ARD (10 Sept) 20%, dawum.de average 20.0%. The 18% threshold sits two percentage points below the polling average, well within the historical margin of error for German state elections. In Berlin's 2021 election, CDU (22.6% final) outperformed polls (18–21%). CDU's core electorate in affluent western districts (Steglitz-Zehlendorf, Reinickendorf) and structural over-representation of older voters underpin the result. No Polymarket market available; own estimate based on historical polling error distribution.

Polymarket market 'Israel Election – Likud seats' (as of September 18, 2026): P(20–24 seats) = 40%, P(<20 seats) = 22.6%, P(25–29 seats) = 27%, P(30–34 seats) = 11%. This yields P(<25 seats) = P(<20) + P(20–24) = 22.6% + 40% = 62.6% ≈ 63%. Political context: current Channel 13 polls (September 2026) show the full Netanyahu bloc at 54 seats vs. Eisenkot bloc at 52 — historically tight. Likud has lost substantial ground since 2022/23 to smaller religious-national parties (Otzma Yehudit, Religious Zionism). Simultaneously, Eisenkot's Yashar party is projected to gain ≥22 seats, structurally weakening traditional large parties like Likud. Polymarket gives Netanyahu only a 31% chance of becoming next PM (Eisenkot: 50%). This prediction complements — and does not contradict — the existing forecast 'Yashar ≥22 seats'.

Polymarket shows 60% probability of a Democratic Senate majority after the 2026 Midterms (as of September 16–18, 2026); Kalshi is around 55%. Drivers: Democrats leading in competitive races in North Carolina, Maine, and Ohio; voter backlash against the Trump-Republican administration (classic midterm pattern); growing dissatisfaction with Fed rate hikes to 3.75–4% and energy price burden. The result would complement the open Cassandra forecast 'Democrats win US House,' creating a fully Democratic-controlled Congress — historically rare in a party's first midterm, but favored by structural factors in 2026. Forecast anchored to Polymarket's 60% probability.
