This market will resolve to the percentage change in the Japanese Consumer Price Index excluding fresh food and energy (All items less fresh food and energy, change from the previous year (%)) between 2025 and 2026 according to the Consumer Price Index Annual Report by the Statistics Bureau of Japan (SBJ). The resolution source for this market will be the SBJ Consumer Price Index Annual Report released for 2026 (https://www.stat.go.jp/english/data/cpi/1588.html#nen), currently scheduled to be released on January 22, 2027. Resolution of this market will take place upon release of the aforementioned data. Note: the resolution source for this market will be the official SBJ Consumer Price Index Annual Report, which reports percentage change in the Consumer Price Index over 12-month periods to only one decimal point (e.g., 2.8%). Thus, this is the level of precision that will be used when resolving the market. For the avoidance of doubt, this market resolves on the core-core CPI figure — the all items index excluding fresh food and energy — not the headline all items CPI figure. If the SBJ does not release the relevant figures on the scheduled date, this market may remain open up until March 31, 2027. If the information is not released by that time, this market will resolve to the lowest bracket.Recent July 2026 core-core CPI (excluding fresh food and energy) printed at 1.9% YoY, up from 1.7% in June but still subdued amid government energy subsidies and base effects, keeping the measure below the Bank of Japan’s 2% target for an extended period. Trader sentiment remains closely balanced between the ≤1.9% and 2.0-2.4% brackets because monthly readings have moderated while the BOJ’s July outlook projects underlying inflation rising clearly above 2% in the second half of fiscal 2026, driven by wage pass-through in a tight labor market, yen depreciation lifting import costs, AI-related semiconductor demand, and lagged effects from elevated crude oil prices tied to Middle East tensions. Market-implied odds reflect uncertainty over the pace of these cost pressures versus subsidy offsets and potential demand softening, with upcoming September CPI releases and the BOJ’s next policy decision serving as key near-term catalysts for shifts in the annual 2026 outcome.
