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

• ≥3.0% (39%): Currently commanding the highest probability, ≥3.0% is heavily favored by the order book. Traders looking to back this outcome face a “Buy Yes” contract price of 39¢, signaling a high degree of market conviction. This contract alone has generated $16.9K in volume.

This market will resolve according to the seasonally adjusted and annualized GDP "Advance Estimate" release for Q3 of 2026, scheduled for October 29, 2026.

If the reported value falls exactly between two brackets, then this market will resolve to the higher range bracket.

The GDP release will be made available here: https://www.bea.gov/data/gdp/gross-domestic-product

Note: data in the first available GDP report is labelled by the BEA as an "Advance Estimate". The data found in the advance estimate 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 release of the advance estimate will not be considered for this market's resolution.

If the advance estimate is not released, this market will resolve based on the first officially published figure for real GDP for the specified quarter (e.g., the ‘second’ or ‘third’ estimate, etc.), as reported by the BEA. If no official estimate is released by the date the next quarter's advanced estimate is scheduled to be published, this market will resolve based on the most recent previous figure released by the BEA.

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.

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

• The Most Overvalued Outcome ≥3.0% currently trades at 39%, but our AI places its Fair Value at just 34.9%. This creates a large negative EV Gap of -4.1%, suggesting the crowd may be overhyping this outcome and driving the premium too high.
