72% — the median of 6 frontier models, resolving by 2027-10-30.

Answer

Gemini (Google): 82% — IPCC plenaries face intense diplomatic brinkmanship over fossil fuel language, but consensus budgets almost always pass before cycles fail. The IPCC plenary must approve AR7 finances, and historical precedent shows states compromise on interim figures rather than freeze operations. A full year gives the Secretariat two plenary sessions to dilute contentious work-program wording to appease petrostates. An outright walkout by major donors or a prolonged diplomatic boycott of WMO/UNEP funding would force a downward revision.

Answer

Claude (Anthropic): 62% — Hinges on whether fossil-fuel-state resistance breaks at a plenary before October 2027. IPCC plenaries occur roughly annually and budget disputes historically get resolved through compromise within 1-2 sessions. Long runway to Oct 2027 gives multiple plenary opportunities, raising odds versus a near-term deadline. Persistent fossil-fuel-state blocking or a funding walkout (e.g., US withdrawal precedent) could extend the impasse past this window.

Answer

GPT (OpenAI): 72% — A consensus budget decision at an annual IPCC plenary is likely before the next assessment cycle needs full-scale work. IPCC member governments must adopt the budget by consensus, with annual plenaries offering several chances before October 2027. UN scientific bodies usually bridge funding disputes rather than halt operations, but fossil-fuel-dependent states can delay agreement. A major donor withdrawal or a sustained bloc veto through the 2027 plenary would materially lower the odds.

Answer

Grok (xAI): 71% — IPCC-65/66 plenary must adopt the AR7 budget by consensus before mid-2027. IPCC plenaries occur ~annually; the next two fall well before 30 Oct 2027 and historically always pass a cycle budget. Saudi, Russia and (if Trump) US have delayed but never vetoed an entire reporting-cycle budget; EU/China extra pledges usually break the logjam. A second Trump term plus simultaneous OPEC+ walkout would be the only development that could push approval past the deadline.

Answer

DeepSeek (DeepSeek): 72% — IPCC budget votes have never failed outright; the question is whether the 2027 plenary slips past October. IPCC budgets are adopted by consensus at plenary sessions; in 35 years it has never failed to pass one, even amid US and Saudi resistance. The 2027 plenary is expected around mid-year, but the last cycle's schedule slipped repeatedly, so timing is the real risk. Fossil-fuel states can delay but rarely block outright; they extract concessions on wording rather than kill the budget.

Answer

Qwen (Alibaba): 83% — The IPCC has never failed to approve a budget; institutional necessity and multiple plenary windows make eventual approval near-certain. The IPCC has approved its budget at every plenary in its 36-year history; no precedent exists for prolonged non-adoption. At least one to two plenary sessions will occur before Oct 2027, each providing a formal opportunity for adoption. AR7 scoping is already underway, creating acute pressure on holdout states—blocking the budget would visibly stall the entire assessment cycle.
