Israel withdraws from Lebanon by December 31, 2026?

Prediction markets put the probability at 10%: Israel withdraws from Lebanon by December 31, 2026. Currently, markets see this as unlikely (10% YES).

What’s Happening

The United Nations Security Council voted on August 28, 2025 to extend the UNIFIL peacekeeping mission in southern Lebanon for a final 16-month term, setting a hard deadline of December 31, 2026 for the force’s mandate to end. Under the French-sponsored resolution, UNIFIL’s approximately 10,800 peacekeepers will then have one year—through the end of 2027—to conduct an “orderly and safe drawdown and withdrawal,” handing over security control to the Lebanese Armed Forces. The vote, which passed unanimously, came after the United States initially demanded a six-month extension before settling on the longer timeline, while Israel had pushed for an even swifter end to the mission that has operated near the Blue Line since March 1978.

The question of whether Israel withdraws from Lebanon by the end of 2026 remains deeply uncertain, as the UNIFIL drawdown timeline does not automatically compel Israeli troop movements. Under the November 2024 ceasefire that ended more than a year of hostilities between Israel and Hezbollah, UNIFIL was integrated into a five-member committee supervising the truce, but Israeli forces have maintained a continued presence in southern Lebanon despite expectations of a full pullout. The Security Council resolution explicitly links the peacekeeping withdrawal to the Lebanese Army’s capacity to secure the border region, yet Beirut has stated that an international force is still needed after UNIFIL departs, highlighting the fragility of the current security arrangement.

Recent violence underscores the stakes: on March 31, 2026, three UN peacekeepers were killed in southern Lebanon within 24 hours amid renewed Israel-Hezbollah clashes, marking one of the deadliest incidents for the force in years. The structural factor that will determine whether Israel withdraws from Lebanon is the disarmament of Hezbollah, a condition Beirut committed to under U.S. pressure but has yet to fully implement. As the December 31, 2026 deadline approaches, the Lebanese Army’s ability to fill the security vacuum—and Israel’s assessment of that capability—will be the decisive variable, with analysts cautioning that a premature Israeli pullout could trigger a new round of conflict.
