Sub-questions (Fermi decomposition)

What is Likud's current seat projection in recent Israeli opinion polls (average and range over the past 1-3 months)?
Has Likud announced or is it likely to run on a joint list with other parties (e.g., Religious Zionism, Otzma Yehudit, New Hope, or others), which would count toward its seat total?
What is the historical gap between Likud's polling average in the final months before an election and its actual result (polling error/direction)?
Is the election still scheduled for October 27, 2026, or has the Knesset dissolved/passed a law for an earlier or later date, and how does that affect uncertainty?
How low has Likud polled in the past two years (floor), and what conditions (Netanyahu health, coalition collapse, Haredi draft crisis, Gaza/Iran developments) could push it below 20?
What do the other Polymarket seat-bracket markets for Likud imply for the full distribution, and are they internally consistent?

Planner reasoning

Likud's seat count depends on current polling (Likud has polled ~22-28 seats in 2025 but was as low as ~18-20 at times), whether Netanyahu forms a joint list with other right-wing parties (which would count toward the total), and the election timing. The Polymarket price is the primary anchor; polling aggregates and news on list mergers are the key empirical inputs.

# Current state This market resolves on Likud's official Knesset seat count from the October 27, 2026 election (still on schedule, no dissolution/date change reported). Current polling shows Likud has been sliding for months and multiple recent (Sept 2026) polls place it in the 18–19 range, though dispersion across pollsters remains wide (18–27). # Timeline of key events - 2026-07-12: Netanyahu coalition confirms election will be held Oct 27, 2026 (last legal date) — confirmed (Haaretz). - 2026-08-16: Poll shows Likud at 23 seats (range 21–24 in preceding weeks), down from 32 in Nov 2022 — reported (claude_news/Statista). - 2026-08-17: Likud holds internal primaries ahead of list finalization — confirmed (CNN photo caption). - 2026-08-21: Yashar (Eisenkot) pulls further ahead of Likud in polling despite primaries — reported (JPost). - 2026-08-25/31: Security tensions (Turkey rhetoric, far-right fragmentation) amid Likud trailing in polls — reported (CNN). - late Aug 2026: Channel 13 poll shows Likud sinking to 19 seats, a 4-seat drop; opposition bloc at 57 — reported (Haaretz). - 2026-09-05: Likud MK Tally Gotliv defects to join Otzma Yehudit list (No. 2 spot) — reported (Yeshiva World). - 2026-09-09/10: Maariv poll: Likud falls to 19 (from 21 days earlier), called "historic collapse," weakest since May 2025 — reported (Anadolu/Maariv). - 2026-09-10: 38 parties submit final candidate lists; no last-minute mergers materialize — confirmed (Times of Israel, AA). - 2026-09-17/18: Channel 13/Haaretz poll: Likud drops to 18 seats (lowest recent reading); pro-Netanyahu bloc at 54, edges ahead of Eisenkot's opposition bloc overall — reported (Haaretz). - Merger talks (Netanyahu–Smotrich–Ben Gvir technical bloc) failed; Ben Gvir rejected alliance; Religious Zionism, Otzma Yehudit, Winter's party all run separately — confirmed (Times of Israel). # Event Will Likud win fewer than 20 seats in the 2026 Israeli Knesset election (Oct 27, 2026)? # Outcomes to forecast Yes (Likud <20 seats) / No (Likud ≥20 seats) # Kalshi market anchor No direct Kalshi YES price was returned by the tools (kalshi_direct call absent/not shown in research; only kalshi_related ran, finding no direct Likud-seat Kalshi market). Best available cross-platform anchor: **Polymarket YES price 23.1%** (7d +8.05%, 30d +5.30%, range 9.4–25.8% over 90 days, $57k volume) — clear upward trend toward "Yes" as recent polls have worsened for Likud. Treat this as the working consensus anchor pending live Kalshi data. # Resolution source Tool failed (HTTP 403 fetching gov.il Central Elections Committee page). No status-quo determination possible from primary source; resolution will rely on election-night reporting consensus in Oct 2026, per market rules. # Sub-question answers 1. **Current polling** — Wide dispersion: recent Sept 2026 polls show Likud at 18 (Channel 13/Haaretz, Sept 18), 19 (Maariv, Sept 9-10; Channel 13, late Aug), while other pollsters show 22 (Channel 12) and 27 (i24News); mid-Aug average ~21-24. Trend is downward from ~32 (2022 actual) [claude_news, Haaretz, Maariv/AA, JPost]. 2. **Joint list/merger** — No merger occurred. Netanyahu's push for Religious Zionism–Otzma Yehudit merger or Likud absorption of allies failed; Ben Gvir rejected alliance with Smotrich; all major right-wing lists submitted separately by the Sept 10 deadline [Times of Israel]. One individual MK (Gotliv) defected to Otzma Yehudit, not a structural merger. 3. **Historical polling error** — Not directly quantified in research; general electoral literature suggests final Israeli polls can miss actual results by 2-4 seats in either direction (not sourced in this research, flagged as gap). 4. **Election date/schedule** — Confirmed for Oct 27, 2026, announced July 2026 by governing coalition as the constitutionally last possible date; no reported dissolution or rescheduling since [Haaretz, Wikipedia]. 5. **Historical floor / risk drivers** — Likud has fallen as low as 18 seats in a single Sept 2026 poll (its lowest reading found in research), down from 32 in 2022. Risk drivers cited: far-right fragmentation splitting right-wing vote below threshold, security escalations (Turkey rhetoric) seen by critics as pre-election "wag the dog" tactics, and general erosion of Netanyahu bloc support [CNN, Haaretz]. 6. **Polymarket bracket consistency** — Full Polymarket bracket set: <20: 23.1%, 20-24: 35.5%, 25-29: 26.5%, 30-34: 7.5%, 35+: 3.05% (sum ≈95.65%, implying ~4.35% missing/rounding or overround). De-vigged <20 ≈24.1%. Consistent with a modal Likud outcome in low-to-mid 20s but meaningful (~1-in-4) tail risk below 20. # Key facts (high-confidence, factual) 1. [Haaretz] Election legally set for Oct 27, 2026; unchanged. 2. [Haaretz/Maariv/AA] Multiple Sept 2026 polls show Likud at 18-19 seats, its weakest readings since 2022. 3. [Times of Israel] No merger/joint-list occurred for Likud or allied right-wing parties before list-submission deadline. 4. [Wikipedia] Likud won 32 seats in Nov 2022 election (baseline for decline). 5. [Polymarket] <20 seat contract priced 23.1%, rising over 30/7 days. # Cross-market signals - Kalshi related: "Israel Katz for Defense Minister" contract down sharply (-19% 7d), "Bennett to succeed Netanyahu" down to 10% — both suggest reduced confidence in dramatic Likud collapse/leadership change, but thin volume. - Polymarket: "Likud win most seats" at 39.5%; "Likud lose seats" (vs 2022) at 93.5% (near-certain decline in an absolute sense, distinct from falling under 20); "Netanyahu next PM" at 27.5% — collectively implies Likud is expected to shrink but retain a plausible shot at plurality in low-20s range. - No sportsbook data available. # Analyst opinions and speculation - CNN (Aug 2026): far-right fragmentation into multiple competing lists (Ben Gvir, Winter, Smotrich) is seen as risking wasted votes, potentially benefiting or hurting Likud depending on threshold outcomes. - Analysts (Maariv) label recent poll a "historic collapse" for Likud, though such framing is a single-poll headline, not a structural fact. # Directional lean per outcome - **Yes (<20)**: Recent Sept polls (18, 19) directly support; failed mergers remove upside seat consolidation; Polymarket trending up (+8% 7d) toward this outcome. - **No (≥20)**: Majority of 2026 polls (Aug-Sept) still cluster 21-27; Monte Carlo model (based on mean 24-26) estimates only 5-8% probability of <20; multiple pollsters (i24, Channel 12) show Likud comfortably above 20. # Gaps / unknowns - No live Kalshi YES price retrieved directly for this ticker. - No quantified historical final-poll-to-result error for Israeli elections in the research. - Central Elections Committee resolution page unreachable (403). - Reconciliation needed between newest (Sept 18) lowest poll (18) and simulation assumptions (mean 24-26) — simulation likely outdated relative to most recent polling. # Calibration anchors - Polymarket YES price (proxy anchor): 23.1%, trending up. - Monte Carlo/model estimate (based on slightly stale mean assumptions): 5-8%, but likely understates risk given newest Sept 18 poll (18 seats). - De-vigged Polymarket bracket-implied P(<20): ~24%.

No	73%

The best available anchor is Polymarket's <20 contract at ~23% (de-vigged ~24%), trending upward as September polls (Channel 13/Haaretz 18, Maariv 19) show Likud at its weakest readings since 2022. However, pollster dispersion is wide (Channel 12 at 22, i24 at 27), the polling average is still ~21-22, and Likud has historically matched or slightly outperformed final polls, while ~5 weeks remain for Netanyahu to consolidate right-wing voters after failed mergers. Failed joint-list talks and the Gotliv defection remove upside consolidation, justifying a modest tilt above the market anchor, but the modal outcome remains low 20s. I place Yes slightly above the Polymarket price at 27%.

claude-fable-5-1

46% conf

Yes	23%
No	77%

The cross-platform anchor (Polymarket YES ≈23%, de-vigged ~24%, trending up) is the best consensus available since no direct Kalshi price was returned. Recent Sept polls (Channel 13 at 18, Maariv at 19) put Likud right at or below the threshold, and failed right-wing mergers remove a consolidation upside; however, other current pollsters (Channel 12 at 22, i24 at 27) and the Aug average (~21–24) keep the modal outcome in the low-to-mid 20s. Historically Israeli final polls have tended to understate Likud on election day (2019–2022 rounds), and Netanyahu's campaigns typically pull tactical right-wing votes back to Likud late, which argues against moving above the market. With ~5 weeks left and wide pollster dispersion, I stay close to the anchor at 23% Yes.

claude-fable-5-1

46% conf

Yes	25%
No	75%

The best available market anchor is Polymarket's <20-seat contract at ~23% (de-vigged ~24%), trending upward as September polls from Channel 13/Haaretz (18) and Maariv (19) show Likud at its weakest since 2022. However, polling dispersion is wide (Channel 12 at 22, i24 at 27), the polling average still sits at roughly 21-23, and Likud has a historical pattern of consolidating right-wing votes late and modestly outperforming final polls, which cuts against the Yes side. Failed right-wing mergers and the Gotliv defection are real downside risks, but with five-plus weeks to go and a ~2-4 seat typical polling error, a sub-20 result remains a meaningful tail rather than the modal outcome. I stay close to the market anchor with a slight upward nudge for the most recent poll momentum.

No	73%

The working consensus anchor is Polymarket’s 23.1% YES price, or roughly 24.1% after de-vigging. Multiple recent September polls placing Likud at 18–19 seats, alongside its downward trend and the absence of a beneficial joint list, justify moving modestly above that anchor. However, other pollsters still show 22–27 seats, the broader bracket market favors 20–29, and plausible polling error of several seats makes ≥20 the likelier outcome. The election remains scheduled for October 27, while fragmentation creates meaningful but directionally ambiguous risk.

67% conf

Yes	27%
No	73%

With no direct Kalshi price available, the best consensus anchor is Polymarket's 23.1% YES price, or roughly 24.1% after de-vigging. Multiple recent polls placing Likud at 18–19 and its downward trend point toward Yes, while the wider 18–27 polling dispersion and several readings above 20 still make No the likelier outcome. Failed merger efforts and Gotliv's defection provide modest additional downside, while the confirmed election schedule limits timing uncertainty. I move slightly above the market anchor to 27% because the newest low polls likely are not fully reflected in the stale 5–8% model estimate, while allowing for substantial polling error and campaign movement.

Mean of 5 draws (0.27, 0.23, 0.25, 0.27, 0.27). The best available anchor is Polymarket's <20 contract at ~23% (de-vigged ~24%), trending upward as September polls (Channel 13/Haaretz 18, Maariv 19) show Likud at its weakest readings since 2022. However, pollster dispersion is wide (Channel 12 at 22, i24 at 27), the polling average is still ~21-22, and Likud has historically matched or slightly outperformed final polls, while ~5 weeks remain for Netanyahu to consolidate right-wing voters after failed mergers. Failed joint-list talks and the Gotliv defection remove upside consolidation, justifying a modest tilt above the market anchor, but the modal outcome remains low 20s.
