THE PANEL'S BRIEF, WRITTEN BEFORE THE OUTCOME
Panel about even, clustered near 52% with a sharp minority lowballing the outcome
The panel mean is 49% and the forecasts range from 3% to 62%. Most models cluster around 52%, and 17 of 20 lean YES. The split is driven by a small group assigning very low probability (Mistral Large and GPT-5 Mini) versus a cluster assigning just-above-50% probabilities (many models around 52% up to Gemini 2.5 Flash at 62%). Records mostly do not provide theses or drivers, so the central tendency rests on many similar, lightly expressed YES leanings rather than detailed arguments.
- Mean chance of YES is 49%, median chance of YES is 52%.
- Highest forecast 62% (Gemini 2.5 Flash), lowest 3% (GPT-5 Mini).
- 17 of 20 models are recorded as leaning YES.
- Many models are tightly clustered at or near 52%.
- Nearly all records include no thesis, drivers or sources.
