Recent U.S. CPI data showing a modest reacceleration to an expected 3.6-3.7% year-over-year headline rate for September 2026, up from 3.4% in August, combined with the Federal Reserve’s September rate hike to the 3.75-4.00% target range and updated projections for 3.7% PCE inflation this year, underpin trader views that inflation will remain sticky above the 2% target. Core CPI has held near 2.4% amid persistent shelter costs, while FOMC participants anticipate at least one additional quarter-point hike by year-end and see upside risks to prices from a resilient labor market and growth near 2.3%. Prediction markets price only modest odds of new 2026 highs beyond the May peak of 4.2%, with upcoming September CPI and October FOMC decisions as near-term catalysts that could shift rate-path expectations and inflation trajectories.
