The official BLS September 2026 CPI release, issued today, showed core inflation (all items less food and energy) rising 0.3% month-over-month and 2.6% year-over-year, exactly matching the Polymarket's dominant outcome. This print exceeded the 2.5% consensus forecast and followed August's 2.4% reading, reflecting persistent shelter costs alongside firmer goods and services prices amid elevated gasoline-driven headline inflation of 3.7% YoY. With the data now public and traders holding real capital positions, market-implied odds reflect near-certainty on the precise 2.6% figure. Only an unexpected late revision or reinterpretation of seasonal adjustments could realistically alter the outcome.
