Six frontier AI models put this at 18% by 23 Jan 2027. Full reasoning from every model.

18% — the median of 6 frontier models, resolving by 2027-01-23.

Answer

Gemini (Google): 28% — Unlocking blocked main arteries depends on stalled UN-Saudi-Houthi negotiations that lack momentum within this brief window. Despite June 2024 partial civilian reopenings, Houthis maintain security checkpoints and block key heavy humanitarian logistics. A 90-day horizon is too tight for formal UN verification without broader progress on the UN Yemen roadmap, which remains frozen. A formal bilateral agreement between the PLC and Ansar Allah in Amman would flip odds upward, but military friction limits trust.

Answer

Claude (Anthropic): 22% — Depends on whether Houthi-STC/government talks on Taiz corridor produce a verified reopening before Jan 2027. Taiz siege has persisted since 2015 with only partial, temporary road openings despite years of UN/Omani-mediated talks. Houthis use siege leverage strategically, so full reopening likely requires a broader political/ceasefire deal, not yet imminent as of late 2026. Partial easing or humanitarian corridor announcements are plausible, but full confirmed reopening of main routes by Jan 2027 remains unlikely given the decade-long…

Answer

GPT (OpenAI): 31% — It hinges on whether Oman- and UN-backed truce talks can convert local road proposals into durable Houthi implementation. The Houthis and Yemen’s internationally recognized government must agree on routes, checkpoints, security, and revenues before access opens. Taiz road talks have repeatedly stalled since the April 2022 truce; partial openings elsewhere have not broken the city’s blockade. A renewed nationwide ceasefire or a verified prisoner-payments deal before January would materially raise the odds.

Answer

Grok (xAI): 11% — Houthi leadership must reverse a decade-long siege tactic in under 90 days. Ansar Allah has held the northern/western Taiz roads since 2015 as leverage; no UN-verified main-route opening occurred even during the 2022 nationwide truce. A broader Riyadh–Sana’a political deal would have to materialize first, yet talks remain stalled with no scheduled round before January 2027. Only an abrupt Saudi or US security concession that Houthis publicly trade for access would shift this; none is on the calendar.

Answer

DeepSeek (DeepSeek): 7% — Only a Houthi political decision to trade the Taiz siege for concessions can open the roads, and none is on the table. The Taiz front has been static since the 2022 truce lapsed; Houthi siege lines around al-Hawban and the eastern ring road have not shifted in years. UN OCHA access negotiations run through the Taiz Humanitarian Access Committee, which has logged no corridor reopening since the 2019 Stockholm deal's failed Taiz… A Saudi-Houthi back-channel deal trading Taiz road openings for border concessions is the only plausible trigger, and no such talks are scheduled before January 2027.

Answer

Qwen (Alibaba): 14% — Houthis have treated Taiz encirclement as leverage for a decade; opening requires a concession they've refused even under the 2022 truce. The 2022 UN truce explicitly included Taiz road openings, yet Houthis stalled implementation until the truce lapsed—showing how low this sits on their priority list. A broader Saudi-Houthi political settlement could bundle Taiz access, but no framework agreement has been signed as of late 2025, and 15 months is tight for ratification… The one development that would shift this sharply upward: a formal ceasefire agreement with a verified roadmap clause naming Taiz routes, backed by a monitoring…
