Israel election 2026 odds: is Eizenkot at 56.3¢ value or trap?

Polymarket prices Gadi Eizenkot at 56.15¢ — a 56.5% probability once the 19-leg field is normalised — to be sworn in as Israel’s next prime minister after the October 27, 2026 election. Our estimate is 57%, which makes the edge roughly half a percentage point (pp): this contract is fairly priced.

That is an unusual verdict, and it is the point. The most-quoted poll in the race, Filber’s survey for Channel 14, has Benjamin Netanyahu beating Eisenkot 56–44 on the preferred-prime-minister question — the opposite of the market. But Filber is the only house whose seat poll puts the Netanyahu bloc above the 61 it needs, and the only one asking as a forced two-way. This piece walks the arithmetic, the house effects, and the resolution clause most traders have not read.

The Bet at a Glance:

• Market: “Will Gadi Eizenkot be the next Prime Minister of Israel?” — Polymarket, event volume $33,356,199, 24-hour volume $219,131, liquidity $2,740,773
• Price: 56.15¢ mid (56.1¢ bid / 56.2¢ ask), last trade 55.4¢ = 56.15% raw, 56.5% normalised — Polymarket Gamma API snapshot, August 27, 2026, 10:32 UTC
• Leg depth: $1,669,654 lifetime volume but just $971 in 24 hours, against $101,158 of resting liquidity — same snapshot
• Our estimate: 57% (range 52–62%) — two-stage coalition model built from 25 seat polls and 20 preferred-PM polls published August 2–26, 2026
• Edge: +0.5pp on the YES — inside the noise band and inside the friction; fairly priced, not value
• Catalyst / date: Knesset elections, October 27, 2026; Knesset dissolved July 17, 2026
• Disconfirmation: any mainstream non-Channel-14 poll putting the Netanyahu bloc at 58 or above

One note on spelling: Polymarket lists the contract as “Eizenkot”; the standard English transliteration is Gadi Eisenkot. We use “Eizenkot” for the contract, “Eisenkot” for the politician.

Methodology: how we built the 57%

This is a two-stage conditional estimate, not a poll average, because becoming prime minister of Israel is not the same event as winning the most seats.

Stage one asks whether the Netanyahu bloc — Likud, Religious Zionist Party, Otzma Yehudit, Shas and United Torah Judaism — falls short of 61 of the 120 Knesset seats. We took every seat poll published August 2–26, 2026 (25 of them, from Midgam Project, Midgam R&C, Kantar, Lazar, Maagar Mochot, Direct Polls, Yossi Tatika and Filber), using the bloc column rather than noisier party-level figures. Stage one: 74%.

Stage two asks whether Eisenkot specifically is sworn in, conditional on the bloc falling short. This weighs Yashar’s seat share against its partners, the preferred-PM series, and the real probability that no coalition forms at all and Israel goes to a repeat election. Stage two: 78%.

0.74 × 0.78 = 57.7%, rounded to 57% with a 52–62% range. The caveats are real: samples are mostly 500–560, polling day is two months away, Israeli polls have historically understated the right, and stage two is a judgement rather than a measurement.

The market, the price, and the 99.35¢ field

This is one of the largest political books on Polymarket: $33.4m of lifetime volume and $2.74m of resting liquidity. Nineteen candidate legs carry a price and sum to 99.35¢ — a slight underround, the opposite of a sportsbook’s overround. Normalising the Eizenkot leg against that field lifts it from 56.15% raw to 56.5%. Netanyahu normalises to 26.7%, Naftali Bennett to 7.6% and Avigdor Lieberman to 4.1%.

Sources: Polymarket Gamma API snapshot, August 27, 2026, 10:32 UTC; our two-stage coalition model. Normalisation is proportional across the 19 priced legs, which sum to 99.35¢.

Is Eizenkot at 56.15¢ value? On our numbers, no — and equally, not a trap. A 57% estimate against a 56.5% normalised price is an edge of half a percentage point, which is smaller than the standard error on any single input we used. It is also smaller than the friction. The quoted spread is tight at 0.1¢, but the leg turned over just $971 in the past 24 hours against $101,158 of resting liquidity, so anything beyond a token position walks the book rather than trading at mid. Add withdrawal costs and a long holding period to resolution, and carrying cost exceeds the theoretical edge. The honest description is that this contract is priced correctly, and that the interesting question is not whether to take a side but why the loudest public poll in Israel disagrees with a market that has $33m riding on it.

“The problem, as we know, is not only to form a government, but to govern,”

— Jack Drassinower, political scientist specialising in Israeli politics (The Jerusalem Post / The Media Line, August 24, 2026)

The seat arithmetic says the Netanyahu bloc is about 10 short

The Knesset has 120 seats, a 3.25% threshold, and a prime minister needs 61 members behind him. Across 25 seat polls published in August 2026, the Netanyahu bloc averaged 52.6 seats. Strip out Filber and it falls to 51.2. Strip out Filber and Direct Polls — the two houses with a visible pro-Netanyahu lean — and the remaining 18 average exactly 50.0, range 43 to 53.

Only three of those 25 polls put the bloc at 61 or above. All three are Filber.

Sources: as published by Kan 11, Channel 14, Maariv and The Times of Israel / Zman Yisrael. Table shows 10 of the 25 August polls in our sample.

Look down the Yashar column, then the Likud column. Yashar sits at 23 or 24 in every one of these polls, Filber’s included — the houses do not disagree about Eisenkot at all. The entire divergence lives in the Likud line, where Filber prints 32, 32 and 33 while the rest of the field prints 19 to 26. Filber is not measuring a different Eisenkot; it is measuring a different Likud. That is the most useful fact in this market, because it isolates the outlier to one party’s vote share rather than a wholesale disagreement about the race.

One structural change in August moved real seats. On August 19, Hadash, Ta’al and Balad re-formed the Joint List under Youssef Jabareen. Balad had been polling below the 3.25% threshold alone, wasting votes that inflated everyone else’s seat count. In Midgam Project’s own Channel 13 series, the Arab-party line went from five seats on August 19 to 10 on August 26, and the Netanyahu bloc reading fell from 51 to 48. Threshold mechanics, not a swing in opinion.

Why the Channel 14 poll everyone quotes is the outlier

The preferred-prime-minister question is where the contradiction with the market appears to live, and where it dissolves on inspection. Filber’s August 24 survey for Channel 14 has Netanyahu 56, Eisenkot 44. Every other house in the field has it the other way.

Sources: as published by each outlet. Across all 20 preferred-PM polls published August 2–26, 2026, Eisenkot led in 13, Netanyahu in six and one was tied; four of Netanyahu’s six leads were Filber surveys. Excluding Filber: Eisenkot 13, Netanyahu two, one tie, from 16 polls.

The mechanism is visible in the third column. Filber’s two numbers sum to exactly 100 in all four of its August surveys, because it offers a straight binary. Every other house offers “neither” or “undecided”, and those options absorb between 10 and 29 points. Excluding Filber, the August average is Netanyahu 37.1 against Eisenkot 42.9, with roughly a fifth of the electorate declining to pick either man. A forced two-way does not measure the same quantity as an open question, and it flatters the better-known incumbent, because undecided respondents made to choose default to the name they recognise. Channel 14’s result is not necessarily wrong about its own question — it is quoted as though it answers a question it did not ask.

So does the polling contradict the 56.15¢ price? No — it corroborates it. Once you set the forced-binary house aside, 13 of 16 August surveys put Eisenkot ahead on preferred prime minister, with an average lead of just under six points, and 22 of 25 seat polls leave the Netanyahu bloc around 10 short of 61. The Jerusalem Post’s report of Channel 12’s August 25 survey found 44% of respondents said Eisenkot was more suitable for the position, against 34% for Netanyahu. A market at 56.5% is not defying the evidence; it is close to the number the evidence implies, which is precisely why we cannot find an edge in it. The trend also runs one way: in March, Midgam had Netanyahu ahead 43–31, and by mid-April Lazar still had him up 45–38. That gap has closed and reversed over five months.

The case against: leading the polls is not being sworn in

The strongest argument for a number below 56.5% is that this contract does not pay out on winning the election. It pays out on being formally sworn in as prime minister, and Polymarket’s rules are explicit that “any interim or caretaker Prime Minister will not count toward the resolution of this market.”

That distinction has bite in Israel, because even on friendly arithmetic Eisenkot’s path is narrow. The Times of Israel’s own poll, by Yossi Tatika on August 19–20 (n=500, 4.4% margin of error), put the Netanyahu bloc on 51 and the anti-Netanyahu parties excluding Hadash-Ta’al-Balad and Ra’am on 57. Getting from 57 to a majority means adding Ra’am’s five — a coalition of 62, one seat wider than the minimum, assembled from Yashar, Bennett’s Together, the Democrats, Yisrael Beiteinu and an Islamist party, and holding together long enough to be sworn in. That is the 2021 Bennett–Lapid arrangement rebuilt with new personnel, and that government lasted a year.

There is also a fragmentation risk that has nothing to do with Netanyahu. Israel’s 3.25% threshold destroys votes, and the anti-Netanyahu side carries several lists hovering near it — Blue and White, Zionist Home and Gilad Erdan’s Unity all polled below the line in August. Every anti-Netanyahu list that lands at 3.1% hands the other bloc seats for free.

“Anyone who does not have six seats should either unite or withdraw,”

— Matan Kahana, Col. (res.), senior member of Yashar and former minister, speaking to radio station 103FM (The Jerusalem Post, August 26, 2026)

Kahana is a member of Eisenkot’s own party, describing his side’s central weakness in public two months before polling day — the case against the market, made from inside the favourite’s camp.

Where this bet breaks

The read that this contract is fairly priced rests on assumptions that can fail. It breaks if any of these fire:

• A mainstream, non-Channel-14 poll puts the Netanyahu bloc at 58 or above. Stage one rests entirely on the bloc sitting about 10 seats short across every house but one. Kantar, Midgam or Lazar printing 58 would mean the gap is closing rather than one pollster being an outlier, and 57% would be too high.
• Lieberman or Ra’am publicly rules out sitting with Eisenkot. Stage two assumes a 62-seat coalition is assemblable. It requires Yisrael Beiteinu and Ra’am simultaneously. Either one ruling it out removes the only arithmetic path that does not depend on the Joint List, and the estimate falls sharply — this is the single most damaging headline the position can take.
• Yashar slips behind Likud on seat share outside the Filber and Direct Polls houses. Yashar has been the largest single party in 15 of 25 August polls. If Kantar or Midgam start printing Likud ahead, the premise that Eisenkot is the natural head of his bloc weakens and value migrates towards the Bennett leg at 7.5¢.
• The swearing-in does not happen inside the window. Polymarket resolves to “Other” if no prime minister is sworn in by the deadline. Israeli coalition formation routinely runs months past an election, and a failed formation triggers a repeat election.

What to watch, and the resolution clause traders are missing

The catalyst is October 27, 2026, but the resolution date is worth checking first. Polymarket’s event metadata shows an end date of December 31, 2026, while the market’s own rules text says the contract resolves to “Other” only if no prime minister is sworn in by December 31, 2027 — fourteen months apart. We flag the discrepancy rather than resolve it; anyone modelling this as an instrument that settles weeks after the election should confirm it against the market page.

Three windows matter between now and polling day. Final candidate lists are filed in September, when the threshold picture for Blue and White, Zionist Home, Unity and Winter’s party stops being speculative. Merger talk on the anti-Netanyahu side — Kahana’s six-seat ultimatum is the opening bid — changes the wasted-vote arithmetic directly. And the Kan 11, Channel 12 and Channel 13 series are the ones to track for the 58-seat trigger: largest samples, least visible house effect.

A note on our own house view. On August 11, with Eisenkot at 51.45¢, we estimated the true probability at 47% and called the leg 5.8pp rich. We are revising up to 57%, for dated reasons: that piece rested on four national polls, against 25 seat and 20 preferred-PM polls from August alone; the preferred-PM series has turned to Eisenkot outside the Filber house; the Joint List re-formed on August 19, removing wasted votes; and the Bennett-merger trigger we flagged has not fired — Yashar polls 23 to 26 against Together’s 13 to 16. The price moved 4.7¢ in our face over sixteen days, and the market was closer to right than we were.

FAQ

What are the odds on Gadi Eisenkot becoming Israel’s next prime minister?

Polymarket priced the “Will Gadi Eizenkot be the next Prime Minister of Israel?” contract at 56.15¢ as of 10:32 UTC on August 27, 2026 — 56.1¢ bid, 56.2¢ ask, last trade 55.4¢. That is a 56.15% raw market-implied probability, or 56.5% normalised across the 19 priced legs, which sum to 99.35¢. Netanyahu is second favourite at 26.50¢, Naftali Bennett third at 7.50¢.

Is Eizenkot at 56.15¢ value?

Not on our numbers, and not a trap either. Our 57% estimate sits half a percentage point above the normalised price, well inside the margin of error on the polling that produced it. The leg also trades thinly — $971 over 24 hours — so realistic execution cost on any size exceeds the theoretical edge. Fairly priced is the accurate description.

Why does the Channel 14 poll show Netanyahu winning?

Filber asks the preferred-prime-minister question as a forced choice between two names, with no “neither” or “undecided” option — its numbers sum to exactly 100 every time. Every other Israeli pollster offers those options, and they absorb 10 to 29 points. Excluding Filber, the August 2026 average is Netanyahu 37.1 against Eisenkot 42.9, and Eisenkot led 13 of 16 surveys.

How many seats does the Netanyahu bloc need, and where is it polling?

A coalition needs 61 of the Knesset’s 120 seats. Across 25 seat polls published in August 2026, only three put the Netanyahu bloc at 61 or above — all three Filber. The other 22 ranged from 43 to 59, averaging 51.2. Excluding Filber and Direct Polls, the remaining 18 averaged exactly 50.0.

When does this market resolve?

The election is October 27, 2026. The contract requires the winner to be formally sworn in — Polymarket’s rules state an interim or caretaker prime minister does not count. Note the event metadata carries an end date of December 31, 2026 while the rules text says December 31, 2027; check the market page before assuming a settlement date.

What would change this analysis?

Four things: a mainstream non-Channel-14 poll putting the Netanyahu bloc at 58 or higher; Avigdor Lieberman or Ra’am publicly ruling out a coalition with Eisenkot; Yashar falling behind Likud on seat share in the Kantar or Midgam series; or a coalition-formation failure that sends Israel to a repeat election instead of a swearing-in.
