**Trader consensus heavily favors a 2.6% year-over-year Core CPI print for October 2026 at 97.5% implied probability, reflecting the data gap created by last year’s government shutdown that prevented official BLS year-over-year calculations.** September’s 2.6% core reading serves as the primary anchor, with unofficial estimates and model-based interpolations clustering tightly around that level despite the November 10 release showing a hotter-than-expected 0.3% monthly core gain. Persistent shelter, recreation, and services components have supported this stability, while the absence of comparable October 2025 data limits volatility in market-implied odds. Realistic challenges include alternative estimation methodologies producing 2.7–2.8% outcomes or post-release revisions that shift aggregated trader positioning.
