September CPI rise above 0.3% fractures above the median
Kalshi ladder
record: CMSIG2026062903 | category: momentum-repricing | target: CM-EVT-F9NPW9F1V9 | published: 2026-06-29
4-bullet brief | narrative
- Kalshi ladder implies a September 2026 CPI print centered near 0.3-0.4%: 52% above 0.3% but only 30% above 0.4%, with sharp tail collapse to 12% above 0.5%.
- The 3-year inflation high reported in late June is consistent with the ladder's above-median lean, though the market stops well short of pricing a breakout print.
- The distribution's sharp drop between 0.3% and 0.4% suggests the market treats 0.4%+ as a tail risk, not the base case.
- Resolves via Bureau of Labor Statistics CPI release for September 2026; each ladder strike settles independently.
