Sub-questions (Fermi decomposition)

What is the current Polymarket price for '2' and for the sibling outcomes (0, 1, 3), and do they sum coherently?
What do the latest polls show for the Saxony-Anhalt Landtag election (Sept 6, 2026) — how large is AfD's lead over CDU and how stable has it been?
What do the latest polls show for Mecklenburg-Vorpommern (Sept 20, 2026) — is AfD ahead of Schwesig's SPD, by how much, and what is the trend?
Is there any plausible path for AfD to finish first in Berlin's Abgeordnetenhaus election (Sept 20, 2026), or is AfD polling far behind CDU/Greens/Linke/SPD?
Are all three elections confirmed for September 2026 with no delay risk, and is there any realistic chance of an AfD party ban or exclusion before then?
Historically, how accurately have German state polls 6-9 months out predicted the first-place party, and how often has a ~5-10 point lead flipped?
Are there cross-market signals (Kalshi or other Polymarket markets on individual state elections, e.g. 'AfD wins MV') that price the pivotal MV race?

Planner reasoning

This market resolves YES only if AfD wins/ties for most seats in exactly 2 of the 3 September 2026 elections (Saxony-Anhalt, Mecklenburg-Vorpommern, Berlin). Saxony-Anhalt looks like a near-lock for AfD and Berlin looks near-impossible, so the outcome hinges almost entirely on whether AfD beats the SPD in Mecklenburg-Vorpommern. Research should anchor on the Polymarket price, check polling trends in all three states, cross-check sibling markets (0/1/3 outcomes), and verify election dates and any risk of delays or party bans.

# Current state Saxony-Anhalt (Sept 6, 2026) is **confirmed decided**: AfD won a landslide plurality (43.8%, 39/83 seats), its best-ever state result — this locks in 1 of the 2 needed wins. The outcome of this Polymarket-mirrored question now hinges almost entirely on Mecklenburg-Vorpommern (Sept 20, 2026), an extremely tight AfD-vs-SPD race whose official results were not yet confirmed in the fetched research; Berlin (also Sept 20) is not competitive for AfD (running third, ~17-18%). # Timeline of key events - 2026 (spring): AfD polling ~41% in Saxony-Anhalt, well ahead of CDU (confirmed — Infratest dimap, article_search). - 2026-08-11: Poll shows majority of Germans oppose the anti-AfD "firewall" (reported — Washington Examiner). - 2026-08-13: Left-wing parties pour record funds into anti-AfD campaigns in eastern states (reported — Zerohedge/Sott). - 2026-08-31: Chancellor Merz booed/heckled at Saxony-Anhalt campaign stops (confirmed — AA, Yahoo). - 2026-09-06: Saxony-Anhalt election held; exit polls and later final results confirm AfD wins outright with 43.8%, CDU 17.2%, AfD 39/83 seats, 3 short of majority (confirmed — Wikipedia, CBS, NPR, CNBC). - 2026-09-13: Mass protests erupt across Germany as AfD eyes further breakthroughs (reported — Times of India). - Mid-Sept 2026: MV polling tightens sharply — INSA/FG Wahlen show AfD ~36-37% vs SPD ~35-37% (near tie); one late ZDF/FG Wahlen poll shows SPD (37%) overtaking AfD after a 3-point jump (reported — 20min.ch, t-online.de, dawum.de). - 2026-09-20: Berlin and Mecklenburg-Vorpommern elections held; voting closes; MV turnout 40.7%; live results ticker running, final seat allocations not yet confirmed in research (confirmed voting occurred; results reported as pending — ZDFheute, BBC). # Event Will AfD win/tie for most seats in at least 2 of the 3 named September 2026 German state elections (Saxony-Anhalt, Mecklenburg-Vorpommern, Berlin)? # Outcomes to forecast Yes / No # Kalshi market anchor No direct Kalshi ticker for this exact event was found (kalshi_direct not returned; kalshi_related found only tangential Chancellor/redistricting markets). **Primary anchor is therefore the mirrored Polymarket market**: current price 56% YES, down sharply from a 30-day high of 89% (7d: -18pp, 30d: -23.5pp), volume $71k over 76 days. This large drawdown likely reflects the late tightening/reversal in MV polling (SPD overtaking AfD in some final surveys). # Resolution source Sachsen-Anhalt Landtag official site confirms the Sept 6 election occurred, results processed, new Landtag to convene Oct 6, 2026 — but page text doesn't state seat totals (corroborated by press as AfD win). MV and Berlin official parliament sites show no election-result content yet (as of ~Sept 18, 2026 fetch) — resolution for those two remains pending in primary sources, though press coverage (Wikipedia, ZDF, BBC) confirms voting concluded Sept 20. # Sub-question answers 1. **Polymarket sibling prices**: "0 wins"=0.05%, "1 win"=42.5%, "2 wins"=56%, "3 wins"=0.9%. Sums to ~99.5% (coherent, minor rounding/vig). [polymarket_related] 2. **Saxony-Anhalt polls/result**: AfD led CDU by large margins (spring polls ~41% vs CDU ~20s); final result AfD 43.8% vs CDU 17.2% — a landslide, confirmed. [Wikipedia, CBS, NPR] 3. **Mecklenburg-Vorpommern**: Essentially tied entering election day — AfD ~36-37%, SPD ~35-37%; one late poll showed SPD (Schwesig) overtaking AfD by 1-2pp after gaining 3pp in final week; other final polls (INSA, FG Wahlen) kept AfD slightly ahead. Trend: AfD surged from 2021 (doubling vote share) but SPD closed gap late via tactical voting campaign. [20min.ch, t-online.de, dawum.de, CNN] 4. **Berlin**: No plausible AfD win path — final polls show Left ~23%, CDU ~21%, AfD third at 17-18%, well behind. [claude_news, article_search] 5. **Delay/ban risk**: No news found of postponement or AfD ban procedure affecting any of the three elections; all proceeded on schedule (SA Sept 6; MV/Berlin Sept 20). [claude_news] 6. **Historical polling accuracy**: Not directly answered in research; Thuringia 2024 precedent shows AfD polling leads translated into actual first-place finishes reliably in eastern German states recently (structural point, not statistical base rate). [CBS] 7. **Cross-market MV pricing**: Polymarket "AfD wins most seats in MV" = 52.5% YES vs "SPD wins most seats in MV" = 47.5% YES — near coin-flip, consistent with polling. [polymarket_related] # Key facts (high-confidence, factual) 1. [Wikipedia/CBS/NPR] AfD won Saxony-Anhalt outright, 43.8% vote, 39/83 seats — confirmed, first of two needed wins locked in. 2. [claude_news/article_search] Berlin: AfD polling third (~17-18%), no realistic path to first place. 3. [multiple] MV is a genuine toss-up between AfD and SPD; final pre-election polls diverge (some show tie/SPD lead, others show AfD lead). 4. [polymarket_related] MV-specific AfD win market = 52.5%; SA and Berlin AfD-win markets are effectively resolved/near-zero respectively. 5. [Wikipedia] Thuringia 2024 precedent: AfD won plurality but excluded from government by coalition — irrelevant to this seat-count question but relevant to "governing" framing confusion. # Cross-market signals - Polymarket "2 wins" market: 56% YES, down 18pp (7d) / 23.5pp (30d) — sharp recent bearish move tracking late MV poll tightening/reversal. - Polymarket "MV AfD wins most seats": 52.5% YES (pivotal race pricing). - Polymarket "1 win" market: 42.5% YES — rising as "2 wins" falls, consistent with MV flipping toward SPD in market pricing. - No Kalshi-specific market or sportsbook data found for this compound event. # Analyst opinions and speculation - CBS/CNN: AfD's SA landslide seen as likely to "mobilise support" for AfD in MV (turnout/momentum effect) — but Wikipedia's MV page also notes the SA result may mobilize anti-AfD (SPD) turnout instead — effect is ambiguous/contested. - Washington Post op-ed frames AfD surge as driven by broad discontent/fear of change, implying durability of AfD support beyond SA. - Code_execution sensitivity modeling: with SA≈certain (p1~0.92-1.0) and Berlin negligible (p3~0.02), P(exactly/≥2 wins) is highly linear in MV probability (p2); at p2=0.55-0.70 model gives 50-66%, centering ~55-60% — closely matching Polymarket's 56%. # Directional lean per outcome - **Yes (AfD wins ≥2)**: SA win confirmed; only needs MV win, which is roughly coin-flip to AfD-favored per most final polls (36-37% vs 35-37%). Market model band (50-66%) supports YES being modestly favored — but the 18-24pp price drop this month signals eroding confidence. - **No**: Requires SPD to win MV, which at least one credible late poll (FG Wahlen/ZDF) now shows, plus AfD's near-zero Berlin chance means no "backup" path. Recent price momentum (down from 89% to 56%) favors the No case strengthening. # Gaps / unknowns - Actual official/confirmed MV and Berlin seat results not present in research (election held Sept 20, resolution unclear per resolution_source tool). - No true Kalshi-native price for this exact ticker was retrieved — relying on Polymarket as proxy anchor. - Conflicting final MV polls (AfD-ahead vs SPD-ahead) not reconciled by any post-election data point. # Calibration anchors - Polymarket (proxy) current YES price: 56%, down from 89% high — treat as anchor with recency-adjusted downward skew. - Precedent: Thuringia 2024 — AfD topped polls and won plurality as polled, supporting reliability of late-stage polling leads in eastern German states, though MV's race is far tighter than Thuringia's was.

Saxony-Anhalt is confirmed (AfD 43.8%, 39/83 seats), and Berlin is effectively out of reach (AfD third at ~17-18%), so the question reduces entirely to whether AfD tops SPD in Mecklenburg-Vorpommern. Final MV polls were a near tie (AfD 36-37% vs SPD 35-37%) with late momentum toward Schwesig's SPD, and the Polymarket MV-specific market sits at 52.5% AfD while the compound '2 wins' market fell from 89% to 56%. The closest precedent, Brandenburg 2024, saw a popular incumbent SPD premier (Woidke) narrowly overtake a polling-favored AfD via last-week tactical consolidation — the same dynamic Schwesig appears to be riding — which argues for shading slightly below the market. Absent confirmed MV results in the brief, I land at a coin flip tilted marginally to No.

Saxony-Anhalt is confirmed (AfD 43.8%, 39/83 seats), and Berlin is out of reach (AfD third at ~17-18%), so this reduces almost entirely to whether AfD tops SPD in Mecklenburg-Vorpommern. Final MV polls were a near tie (AfD ~36-37% vs SPD ~35-37%), with a late FG Wahlen/ZDF poll showing Schwesig's SPD overtaking after a tactical-voting surge — echoing the Brandenburg 2024 precedent where an incumbent SPD premier narrowly beat AfD despite tied polls. Countervailing: AfD outperformed polls in Saxony-Anhalt and most final MV polls still had AfD marginally ahead. The Polymarket proxy anchor is 56% for '2 wins' and 52.5% for the MV-specific market, but the sharp 18-24pp drawdown signals eroding confidence, so I shade slightly below the anchor toward a genuine coin flip.

Saxony-Anhalt is confirmed as an AfD landslide (43.8%, 39/83 seats), locking in one of the two required wins, while Berlin offers no realistic path (AfD third at ~17-18%), so the question reduces almost entirely to Mecklenburg-Vorpommern. Final MV polls are essentially tied (AfD ~36-37% vs SPD ~35-37%), with INSA/FG Wahlen keeping AfD marginally ahead but one late ZDF poll showing SPD overtaking after a tactical-voting surge, and the Polymarket compound market has fallen from 89% to 56% while the MV-specific AfD market sits at 52.5%. Given the near-coin-flip pivotal race, the modest historical reliability of AfD polling leads in eastern states, and the fact that a seat tie would count as a win, I land slightly above even at 53% Yes, hewing close to the market proxy but shading down a touch for the bearish momentum in late MV polling.

Saxony-Anhalt already gives AfD one confirmed win, while Berlin offers virtually no backup path because AfD polls a distant third. The event therefore reduces almost entirely to Mecklenburg-Vorpommern, where final polls conflict between a narrow AfD lead and a narrow SPD lead. The proxy Polymarket anchor is 56% YES, while the MV-specific market is 52.5% for AfD; together they support a modest rather than decisive YES advantage. I shade slightly below the 56% compound-market anchor because SPD gained late and led in one credible final poll.

Saxony-Anhalt already gives AfD one confirmed win, while Berlin offers virtually no backup path, so the event reduces almost entirely to Mecklenburg-Vorpommern. MV’s final polling was effectively tied: some surveys kept AfD narrowly ahead, while a late ZDF/FG Wahlen poll put SPD ahead after a late gain. The 56% YES Polymarket anchor and 52.5% MV-specific AfD price both imply a modest AfD edge, though the sharp recent decline warrants staying close to even odds. I therefore place YES slightly below the compound-market anchor at 54%.
