4-bullet brief | narrative

Kalshi ladder pins the Fed funds upper bound near 4.0%, with 88% above 3.75% but only 47% above 4.0%.
Hot August CPI print is consistent with the market pricing a rate path that clears 3.75% but stops short of 4.25%, where odds drop to 13%.
The sharp cliff between 4.0% (47%) and 4.25% (13%) reflects the market treating 4.0% as the ceiling of the most likely outcome, not a stepping stone.
A companion Kalshi ladder (CM-EVT-4ZQLQPNH91) shows 81% above 3.75% but only 2% above 4.0%, suggesting the two contracts differ on the precise terminal bound -- traders should note the resolution horizon difference.
