Japan GDP growth in Q2 2026 (QoQ Annualized)?

According to the latest prediction market data for the query “Japan GDP growth in Q2 2026 (QoQ Annualized)?”, traders have formed a strong consensus.

Currently, 0.0%–0.8% is dominating the market with an overwhelming 60% chance of winning. 1.6%–2.4% follows in second place at 45.5%, while -2.4%– -1.6% sits in third with 44.5%. The betting volume for this specific market has already reached $427, reflecting intense industry interest.

To better assess where each potential outcome stands, the market can be segmented into three distinct trading tiers based on implied probability and contract pricing:

🥇 Tier 1: The Dominant Leader

• 0.0%–0.8% (60%): Currently commanding the highest probability, 0.0%–0.8% is heavily favored by the order book. Traders looking to back this outcome face a “Buy Yes” contract price of 60¢, signaling a high degree of market conviction. This contract alone has generated $19.8K in volume.

🥈 Tier 2: The Primary Challengers

• 1.6%–2.4% (45.5%): Positioned as the most viable alternative, 1.6%–2.4% maintains a 45.5% chance of resolving true. Its “Buy Yes” shares currently trade at 46¢.
• -2.4%– -1.6% (44.5%): Sitting in third place with a 44.5% probability, the market shows measured skepticism toward -2.4%– -1.6%, treating it as an outside wildcard unless momentum shifts.

🥉 Tier 3: The Long-Tail Options (Combining for ~0%)

Beyond the top three choices, a wide field of macro variables and long-shot outcomes are being tracked. While their individual probabilities hover low, they represent crucial hedges for speculative traders:

• Alternative Options: This includes 3.2%–4.0% (44.5%), <-2.4% (43%), and -1.6%– -0.8% (33.7%).
• Speculative Volume: Despite low statistical likelihood, certain long-tail contracts like -0.8%–0.0% are still attracting notable interest.

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.

While human consensus and speculative volume shape the broader prediction market, our quantitative algorithms offer a data-driven counter-perspective. By analyzing fundamental signals, underlying trends and historical distributions, our AI Valuation model calculates an independent “Fair Value” probability for each outcome.

Comparing this Fair Value against the current Trade Value uncovers major disparities — known as the Expected Value (EV) Gap. Contracts with a positive EV Gap represent statistically underpriced outcomes, whereas a negative EV Gap flags a potential market overreaction.

Top AI Alpha & Mispriced Arbitrage Opportunities

Based on the latest data model run, several key contracts stand out with significant deviations:

• The Most Overvalued Outcome 0.0%–0.8% currently trades at 60%, but our AI places its Fair Value at just 31.5%. This creates a large negative EV Gap of -28.5%, suggesting the crowd may be overhyping this outcome and driving the premium too high.
• The Best Value Play (Highest EV) Our model identifies 0.8%–1.6% as the premium value opportunity on the board. While the market only assigns it a 15% trading probability, our AI’s Fair Value assessment sits at 15.4% — yielding an impressive +0.4% EV Gap.
• Under-the-Radar Dark Horses Other notable discrepancies include 2.4%–3.2% (EV Gap: +0.1%). These long-tail opportunities are heavily discounted by the live order books despite stronger statistical backing from our predictive model.
