Gantz Drops to 18% to Become Israel's Next PM as Party Polls at 0.6%

Benny Gantz's National Unity Party is polling at 0.6% of the vote. Israel's electoral threshold for entering the Knesset is 3.25%. A party that cannot clear that barrier cannot win seats, cannot join a coalition, and cannot produce a prime minister. According to Chatham House, the party that once led polls with 29 projected seats has collapsed to a rounding error in the electorate.

Prediction markets have responded accordingly. Gantz's implied probability of becoming the next Prime Minister of Israel has dropped from 26% to 18% in roughly 72 hours, an 8-percentage-point decline that represents a 31% relative reduction in the market's confidence.

Benny Gantz's Path to Prime Minister Is Disappearing in Real Time

The arithmetic is unforgiving. Israel's proportional representation system requires a party to clear 3.25% of the national vote to win any Knesset seats at all. At 0.6%, the National Unity Party is not merely underperforming; it is functionally extinct as an electoral vehicle. No seats means no coalition leverage. No coalition leverage means no path to forming a government. Gantz cannot become prime minister through a party that does not exist inside parliament.

This represents a historic reversal. As recently as September 2024, a KAN News/Kantar Institute poll showed National Unity leading all parties with 29 projected seats, three ahead of Benjamin Netanyahu's Likud. Gantz had positioned himself as the responsible centrist, a former IDF Chief of Staff who joined Netanyahu's emergency war cabinet after October 7 to project national unity above partisan interest.

That brand began disintegrating in June 2024, when Gantz resigned from the emergency government, citing disagreements over Gaza strategy and hostage recovery, as reported at the time. The resignation was designed to reestablish Gantz as an independent force. Instead, it appears to have stranded him between the right and the center-left, with voters migrating to alternatives who offer sharper identities.

Prediction Markets Cut Benny Gantz's PM Odds by Nearly a Third in Three Days

The drop from 26% to 18% is not a noise-level fluctuation. An 8-percentage-point move in a political futures market over 72 hours signals a reassessment of structural viability, not a reaction to a single headline. At 18%, Gantz sits at his period low, with no recovery visible in the trend.

Per-platform pricing tells a fractured story: Kalshi holds Gantz at 2%, Polymarket at 2%, while PredictIt lists him at 50%. The cross-platform spread is unreliable, and those Kalshi and Polymarket figures suggest that on the most liquid venues, the market has already priced Gantz as a near-zero contender. The aggregated 18% figure likely reflects PredictIt's stale or illiquid pricing dragging the composite upward.

If the lower-end prices are closer to true market consensus, 18% is not where Gantz's repricing ends. It is where it pauses. Markets are lagging indicators here: the polling collapse to 0.6% is a fact already recorded by Chatham House, and any further repricing would simply bring prediction prices into alignment with that reality.

What Replaced Gantz? The Competitors Absorbing His Support

Gantz's collapse did not occur in a vacuum. Voters and bettors have reallocated toward candidates who offer clearer political identities. Two figures stand out.

Former IDF Chief of Staff Gadi Eisenkot launched Yashar! (Straight Ahead!), a new party that Britannica reports is polling competitively for third place. Eisenkot occupied the same national-security centrist lane as Gantz but entered the race with fresher credibility and no baggage from the war cabinet resignation. His rise directly cannibalizes the voter base Gantz once commanded.

Former Prime Minister Naftali Bennett has positioned himself as the pragmatic right-wing alternative. Chatham House notes Bennett has refused to rule out forming a government with Netanyahu, a calculated ambiguity that appeals to right-leaning voters who want change without ideological rupture. Bennett's flexibility is the mirror image of Gantz's rigidity, and it is proving more effective at consolidating support.

Netanyahu's Likud remains the dominant bloc. The 2026 elections are widely framed as a referendum on October 7 and its aftermath, terrain where Netanyahu retains a loyal base despite facing corruption charges and widespread criticism of his war management.

The Case for Gantz at 18%: What Would Have to Change

The strongest counterargument is that Israeli politics is volatile enough to produce a late-stage realignment. Gantz retains personal name recognition and a military biography that polls well on security issues. If Eisenkot's Yashar! stumbles, or if Bennett alienates centrist voters by moving too close to Netanyahu, Gantz could recapture the "anti-Netanyahu but not left-wing" lane.

There is also a scenario in which Gantz abandons National Unity and joins or leads a different party list. Israeli electoral law permits such maneuvers close to election day, and a merger with Eisenkot or another centrist faction could instantly restore Gantz's parliamentary viability. At 0.6%, his current party is a liability; shedding it might be the only rational move.

These scenarios deserve genuine weight because Israeli coalition politics routinely produces outcomes that polling three months out fails to predict. But each scenario requires multiple preconditions to align simultaneously. Gantz needs a vehicle into the Knesset, coalition partners willing to nominate him for prime minister, and enough combined seats to form a majority. Right now, he has none of the three.

What 18% Really Means for Bettors

An 18% implied probability prices Gantz as roughly a 1-in-5.5 possibility. For a candidate whose party cannot currently enter parliament, that number is generous. If the Kalshi and Polymarket prices of 2% are more reflective of informed money, the composite figure overstates Gantz's chances by an order of magnitude.

This market resolves on December 31, 2026. Israeli elections are expected later this year, giving Gantz limited runway to rebuild. Every week that National Unity remains below the 3.25% threshold is a week in which his candidacy becomes less viable, not more. The market at 18% is pricing optionality that the polling data does not support. Unless Gantz finds a new political vehicle before election day, the direction of this contract is down.
