Israel election 2026 odds: Yashar 72.5% to win most Knesset seats as hung-Knesset price holds 86%

Kalshi priced Yashar to win the most seats in Israel's legislative election at 72.5% on Tuesday morning, as roughly 7.3 million Israelis began voting. The number that matters more sits one tab away: the same venue held the chance that no bloc reaches the 61-seat majority needed to govern at approximately 86%.

For an event-market reader, the gap between those two contracts is the story of this election. Yashar, the centrist party led by former army chief Gadi Eizenkot, is a clear favorite to finish with the most seats. Final television polls published Friday, Oct 23 by Kan 11, Channel 12 and Channel 13 gave Yashar 22 to 23 seats against Likud's 19 to 21, with B'Yachad, the party co-led by former premiers Naftali Bennett and Yair Lapid, at 14 to 15. The opposition block was projected between 52 and 56 seats, while Netanyahu's bloc landed at 50, nowhere near the 61 that turns a plurality into a government.

That is the structural divide the markets are translating into two different prices. Winning the most seats is one event. Supplying the next prime minister is another, and in a chamber where the largest party cannot on its own reach 61, the first does not guarantee the second. Kalshi sells both, and on Tuesday it priced the gap at roughly 22 points: Yashar at 72.5% for the plurality, Eizenkot at 50.5% to lead the next government. Volume confirms the market is real, not decorative. The Likud most-seats contract had traded over 51,000 contracts and Yashar's over 26,000, while the prime-minister market showed deeper interest, with Eizenkot at 412,000 contracts and Netanyahu's leg above 1.6 million.

Kalshi and Polymarket do not fully agree, and that disagreement is itself the divergence worth reporting. On Polymarket, Eizenkot to be next prime minister traded at 53.9% early Tuesday against 50.5% on Kalshi, a roughly three-point gap in the same direction with Kalshi the more cautious. For the plurality, Polymarket put Yashar at 70.5% and Likud at 29.5%, while Kalshi nudged Yashar to 72.5%. The pattern is consistent: both venues see Yashar winning the chamber, both see Eizenkot's path to power as materially less certain, and Kalshi prices the no-majority risk more heavily, at about 86% for no bloc reaching 61.

That no-majority read lines up with the last word from the polls. All three Friday surveys left Netanyahu's bloc at exactly 50 seats and the opposition short of a working majority without the Arab parties, which were projected at 14 to 16 seats and are not counted in either camp. The central tension the final polls described, a change-block lead that stops short of governing, is exactly what the market's most-seats and prime-minister legs have turned into two different probabilities.

Turnout and the Arab slates make up the bear case against the friendly read. The National reported expectations that Arab turnout could surge from about 50% toward 70%, which would add to the change block's arithmetic even as the Arab-majority parties are excluded from both blocs. With roughly 700,000 first-time voters and 140,000 returning expats adding uncertainty, a two- to three-seat Yashar edge in the polls is thin enough that a single district could swing the plurality. Kalshi's most-seats leg sits at 72.5%, wider than the poll margins, and the premium reflects that plurality is a more mechanical, resolvable call than who forms the next coalition.

What resolves next is the certified count. The voting window runs through 10pm Israel time, when the exit polls are due and the television consortium is set to release its projections. Polymarket's core Israeli markets carry a next-morning end date, set to 03:59 UTC the day after the vote, meaning the near-time legs price a settlement within roughly 24 hours of the polls closing. Kalshi's leg shows a venue-designated close that is effectively a placeholder; the practical resolution is the same certified result that the exit polls and the official count produce.

The cleanest read from the prediction markets is the most important one for a reader trying to separate strength from power. The market is not pricing a coin flip in this election, it is pricing a plurality that is likely and a government that is not. Yashar at 72.5% for the chamber is a confident number. The 86% on no bloc majority is the honest one, and it is why Eizenkot's prime-minister leg trades a full 22 points below his party's most-seats price. That gap is the election, condensed into two quotes.
