Trader consensus on Polymarket has locked in a 100% implied probability for March 2026 US annual CPI inflation at ≥2.8%, directly reflecting the Bureau of Labor Statistics' official release on April 10 showing a 3.3% year-over-year rise—the sharpest since May 2024 and up from February's 2.4%. This surge stems from a 0.9% monthly jump, driven primarily by energy costs soaring 10.9% month-over-month, with gasoline spiking 21.2% amid geopolitical tensions including the Iran conflict, overshadowing softer core CPI at 2.6% YoY. While revisions to preliminary data in future BLS updates pose the only realistic challenge to this near-certainty, the skin-in-the-game pricing underscores unassailable resolution positioning ahead of the May 12 April CPI report and FOMC rate path reassessment.
