Oct 7 forecast

Q expects September annual core CPI to stay at or below 2.4% because subdued monthly gains and softer goods prices limit annual inflation.

Core inflation has shown signs of stabilization following a decline to 2.4% in the 12 months ending in August 2026. While Federal Reserve policymakers note ongoing upward pressures in selected goods and non-housing services, recent monthly trends show softening in medical care and vehicle insurance alongside steady housing metrics. Major nowcasts and Wall Street previews project a 0.2% monthly advance for September, which would hold the unrounded 12-month rate near 2.39% and round to 2.4%. Because the contract strictly requires an outcome above 2.4%, a reported 2.4% resolves to NO. Prediction markets currently treat an above-threshold print as narrowly favored, whereas this assessment relies on tracking estimates and decelerating subcomponents that point to a print at or below the benchmark.
