70% — the median of 6 frontier models, resolving by 2026-12-10.

Answer

Gemini (Google): 88% — UNFCCC parties almost universally prioritize adaptation finance continuity, making a formal extension decision the default path. Developing blocs like AOSIS and the G77 consider the Adaptation Fund vital, so allowing its mandate to lapse without action is untenable. COP decisions facing sunset clauses routinely adopt technical extensions or reform packages, with clean lapses virtually unprecedented. A deadlock over Article 6 share of proceeds integration into the fund could delay final text, but stopgap renewal remains standard.

Answer

Claude (Anthropic): 62% — Hinges on whether Antalya delegates finalize the Adaptation Fund mandate text before the gavel, as COPs usually do for expiring mechanisms. COP decisions on institutional mandates nearing expiry are almost always resolved via formal decision text, often in final plenary hours, giving a base rate above 70%… Adaptation Fund governance has had contentious debates over which agreement it serves (Kyoto Protocol vs Paris Agreement) which could cause last-minute haggling or a… Watch for pre-COP31 subsidiary body (SBI/SBSTA) texts and G77 coordination in mid-2026, since lack of consensus there could push this into a rollover or informal…

Answer

GPT (OpenAI): 68% — The outcome turns on whether CMA/COP parties can package the Fund’s post-2026 mandate into the Antalya finance negotiations. The Adaptation Fund Board and UNFCCC secretariat can supply text, but 198-party consensus is required by 20 November. Expiring institutional mandates are usually addressed at the relevant COP, though finance language often slips into late-night package deals. A visible deadlock over contributor burden-sharing or legal authority after Paris Agreement governance would sharply reduce the odds.

Answer

Grok (xAI): 72% — COP31 must adopt a CMP/CMA decision on AF post-2026 before 20 Nov close. Parties and AF Board must table and agree text in the first week so ministers can gavel it in the second. Fund-expiry items almost always get a COP decision (GCF, LDCF precedents); deadlock is rare when developing countries hold the purse. A public split over share-of-proceeds or Paris-only status would drop odds; none is visible ten days out.

Answer

DeepSeek (DeepSeek): 62% — Whether Antalya's COP31 presidency forces a formal Adaptation Fund mandate decision before gavelling out on 20 Nov 2026. The Adaptation Fund's mandate expires in 2026, so inaction means the fund legally lapses, forcing some decision at COP31. COP presidencies routinely push finance-mandate items to the final plenary, and Antalya's Turkish presidency has flagged adaptation finance as a priority. Base rate: COP decisions on fund renewals (e.g. LDCF, SCCF) usually pass, but often as bracketed text or deferral to CMA, not clean renewal.

Answer

Qwen (Alibaba): 84% — Institutional continuity decisions at COPs almost always clear; the bar here is just any formal extension or restructuring language. The Adaptation Fund is politically vital to G77; letting it lapse without a decision would be a visible failure no presidency wants. The wording 'renew or reshape' is broad—even a one-paragraph rollover decision satisfies it, and such minimal extensions are COP boilerplate. Main downside risk is COP31 getting consumed by the New Collective Quantified Goal follow-through and NDC ratchet fights, pushing this to SB sessions, but that's…
