Kalshi
This market tracks whether core inflation, measured by the Consumer Price Index excluding food and energy, will exceed 2.4% on a year-over-year basis for the twelve-month period ending in May 2026. On Kalshi, the leading outcome—that core CPI will be above 2.4%—stands at 99.0%. Resolution will be determined by the official Consumer Price Index report from the Bureau of Labor Statistics for the twelve months ending May 2026, expected around June 10, 2026. Watch the May 2026 CPI release from the Bureau of Labor Statistics for the definitive year-over-year core inflation figure.
The Core inflation in May 2026 (Core CPI YoY) market resolves on Jun 10, 2026. Resolution is determined by the official year-over-year core CPI figure released by the U.S. Bureau of Labor Statistics for May 2026. The outcome hinges on whether that published rate exceeds 2.9% or not. This is an objective, government-reported metric with no ambiguity, making it a clean settlement event. Traders should monitor BLS release schedules and any revisions to prior months' data, as these can shift expectations in the weeks leading up to the final May reading.
Several catalysts will likely shift odds on this market. Monthly CPI releases between now and May 2026 are the most direct signal; each print either reinforces or challenges the disinflationary trend. Federal Reserve policy decisions and forward guidance will influence inflation expectations, especially if rate cuts or holds surprise markets. Energy and commodity prices, wage growth data, and supply-chain developments all feed into core inflation dynamics. Geopolitical shocks, fiscal policy shifts, and shifts in consumer demand could also move the needle. Watch for any significant revisions to prior months' core CPI figures, as these can reset baseline expectations and trigger repricing across the entire forecast horizon.
