Kalshi ladder

4-bullet brief | narrative

The Kalshi ladder prices 57% above 2.8% and 41% above 2.9%, implying consensus sits in the 2.8-2.9% range for the reference core CPI print.
Trading volume on this ladder rose 187x day-over-day, a strong signal the September 3.7% headline CPI beat is drawing fresh positioning on the disinflation path.
The 8% Kalshi contract on sub-2.2% core CPI (CM-EVT-K0L95NMQ77) and this 2.8-2.9% ladder are mutually consistent: both price a slow, incomplete disinflation trajectory.
Resolution depends on the BLS CPI release; the ladder's implied 2.8-2.9% range is well below the current 3.7% headline, reflecting an expectation that energy-driven spikes are partly transient.
