Prediction: NO Reasoning: 1. Data: GPT-5.6 Pro Elo ~1465, base ~1440, mini ~1392 on Arena Hard. Threshold: 1490. Gap: 25-98 points. 2. Logic: Limited preview means limited Arena votes. Scores won't spike in 24h. No other OpenAI model imminent. 3. Counter: Even on default Arena, GPT-5.6 would need ~25+ Elo gain in 24 hours -- unprecedented.

Plutos status is governed by the IAU, whose 2006 definition classifies it as a dwarf planet. Reclassification requires a formal IAU resolution, only votable at General Assemblies (next: 2027). No such vote is scheduled before June 30, 2026.
