Polymarket
Legislative elections are schedule to be held in Israel on October 27, 2026. This market will resolve to the first individual who is officially tasked by the President of Israel with forming a government following the 2026 parliamentary election. If an election is called early, this market will immediately resolve to the first individual who is officially tasked with forming a government after that election. To count for resolution, the individual must be formally tasked with forming a government by the President of Israel. Recommendations made to the President by parties or members of the Knesset, and the President's consultations, will not count toward the resolution of this market. If no individual is tasked with forming a government by December 31, 2027, 11:59 PM ET, this market will resolve to “Other”. The primary resolution source for this market will be official information from the Government of Israel; however, a consensus of credible reporting may also be used.
