Across 5 frontier models answering independently, the panel is barely on the yes side: the median is 58%.
They do not agree: Grok puts it at 61% and Claude at 4%, 57 points apart. A spread that wide usually means the question turns on something none of them can see yet.
It happened. Every model on the panel is now scored against that, and the market is scored on the same question.
It happened.
The Federal Reserve's own September 16, 2026 FOMC statement confirms it raised the target federal funds rate range by 1/4 percentage point to 3.75%-4%, corroborated by CNBC, Fox Business, and other outlets reporting a 12-0 vote to hike rates at that meeting.
