Japan’s Q2 2026 GDP softened to a preliminary 0.3% quarter-on-quarter (1.1% annualized), below expectations, with domestic demand subtracting 0.2 percentage points amid flat private consumption and weaker capital spending, while net exports added 0.5 points. Markets now price the September 8 revision near 0.4% q/q and 1.6% annualized. For Q3, trader-implied odds cluster tightly around 0–1.6% annualized amid mixed signals: Bank of Japan policy held at 1.0% with hawkish guidance on upside inflation risks from yen weakness and Middle East-driven oil prices, record yen-buying interventions exceeding ¥15 trillion in July–August, and resilient AI-related export demand offset by household cost pressures. These factors sustain uncertainty, keeping probabilities for low-positive versus flat-to-negative outcomes closely contested ahead of September data releases and the next policy meeting.

The relevant figure may be found in the summary document, in table 1-1 'Quarterly Real Growth Rate (Seasonally Adjusted Series, Quarter-to-Quarter)' — this figure expresses the quarterly growth rate compounded over four quarters to produce an annualized equivalent. Changes in the Japan Cabinet Office's GDP reporting format will not disqualify a published figure from counting.
The GDP release will be made available here: https://www.esri.cao.go.jp/en/sna/sokuhou/sokuhou_top.html
If the reported value falls exactly between two brackets, this market will resolve to the higher range bracket.
If no data for the specified quarter is released by the date the next quarter's data is scheduled to be released, this market will resolve based on data from the last available quarter.
Note: the resolution source for this market reports Quarter-over-Quarter Annualized GDP growth rates to only one decimal point (e.g. 2.1%). Thus, this is the level of precision that will be used when resolving the market.
Note: data from the initial release of the referenced GDP report is what will be used to resolve this market. Data may be revised during the following quarter or as a part of the next estimate's publication, however any revisions to GDP report data made after the initial release will not be considered for this market's resolution. For the full release schedule, see: https://www.esri.cao.go.jp/en/sna/kouhyou/kouhyou_top.html
