The Bureau of Labor Statistics' September 11 release confirmed August 2026 core CPI at 2.4% year-over-year, matching consensus forecasts and marking a 0.1 percentage point decline from July's 2.5% print. This outcome aligned with expectations for a 0.3% month-over-month increase and reflected continued moderation in underlying price pressures, particularly in core goods, while shelter costs remained a steady contributor. Trader consensus on Polymarket coalesced around the 2.4% outcome as the official figure became available, underscoring the market's reliance on verified BLS data rather than forecasts. Only an unexpected data revision or reporting anomaly could alter the resolution, though such adjustments are historically infrequent and typically minor.
