Description
This market will resolve according to Japan's real gross domestic product growth rate (Quarter-over-Quarter Annualized, %) in the second quarter of 2026, as reported in the Japan Cabinet Office's Quarterly Estimates of GDP (First Preliminary Estimates) release for Q2 of 2026, scheduled for release on August 17, 2026. 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.

PredictionHero - Resolution Divergence Alerts (RDA)
Divergence Detected
Issue:
Kalshi's resolution criteria reference Germany GDP data while the event group explicitly asks about Japan GDP growth. This subject country mismatch creates a logical contradiction that makes Kalshi's market unresolvable as written and introduces data integrity failure.Hero Tip:
Avoid trading Kalshi until the divergence is corrected. The market cannot be fairly resolved if the trigger data (Germany) does not match the event description (Japan). Contact Kalshi support to confirm whether this is a documentation error. Polymarket offers a clear, government-backed resolution path and should be treated as the authoritative source for this event.Critical Divergence Points:
Polymarket:
Resolves based on Japan Cabinet Office Quarterly Estimates of GDP (First Preliminary Estimates) for Q2 2026, scheduled August 17, 2026. Uses official Japan government data reported to one decimal place precision. Offers 11 bracket-based outcomes: less than -2.4%, -2.4% to -1.6%, -1.6% to -0.8%, -0.8% to 0.0%, 0.0% to 0.8%, 0.8% to 1.6%, 1.6% to 2.4%, 2.4% to 3.2%, 3.2% to 4.0%, and at least 4.0%. Key quote: 'This figure expresses the quarterly growth rate compounded over four quarters to produce an annualized equivalent.'Kalshi:
Resolves based on Germany GDP growth rate QoQ flash for Q2 2026 across 15 binary thresholds ranging from above -0.5% to above 0.9%. No Japan data is referenced. This directly contradicts the event group title which explicitly asks about Japan GDP growth. Key quote: 'If Germany GDP growth rate QoQ flash for Q2 2026 is above [threshold], then the market resolves to Yes.'

Kalshi
The market resolves based on Germany's official flash estimate of quarter-over-quarter GDP growth for Q2 2026. Each outcome represents a specific threshold, with resolution to Yes if the reported growth rate exceeds that threshold. The thresholds range from -0.5% at the lowest to 0.9% at the highest, allowing traders to express views on the precise level of economic growth. The flash estimate, typically released early in the month following the quarter, serves as the official data point for resolution.
Frequently asked questions
Kalshi and Polymarket can show different implied probabilities for the same outcome because of liquidity, fee structure, participant mix, and how each venue defines the contract. Kalshi and Polymarket may price Japan Q2 2026 GDP growth differently due to distinct user bases, liquidity pools, and outcome definitions. Kalshi's binary structure around specific thresholds attracts directional traders, while Polymarket's range-based outcomes appeal to those hedging intermediate scenarios. Differences in order-book depth, fee structures, and geographic trader composition create natural arbitrage spreads. Additionally, each platform's historical resolution track record and perceived credibility influence risk premiums, causing temporary price gaps that often compress as Aug 17, 2026 approaches and information converges.
The market resolves on Aug 17, 2026, following Japan's official GDP release for Q2 2026. The outcome is determined by the annualized quarter-on-quarter growth rate published by Japan's Cabinet Office. This metric measures the seasonally adjusted percentage change in real GDP from Q1 to Q2, then annualized to reflect what the full-year growth rate would be if that quarterly pace continued. Resolution occurs once the preliminary or flash estimate is released, with potential adjustments if revised figures materially change the reported figure.
Key catalysts include Bank of Japan policy decisions, inflation data, wage growth trends, and consumer spending reports. External shocks such as global trade tensions, commodity price swings, or regional geopolitical events directly impact Japan's export-dependent economy. Domestic factors like business investment cycles, government stimulus announcements, and labor market tightness will influence Q2 momentum. Monthly industrial production, retail sales, and PMI surveys provide leading indicators that traders monitor to adjust odds. Currency fluctuations and US economic data also matter, since yen strength and global demand affect Japan's growth outlook heading into the resolution period.
