2026 World GDP Growth

According to the latest prediction market data for the query “2026 World GDP Growth”, traders have formed a strong consensus.

Currently, 3.1% is dominating the market with an overwhelming 46.1% chance of winning. 3.2% follows in second place at 18.7%, while 3.0% sits in third with 16.9%. The betting volume for this specific market has already reached $90.1K, 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

• 3.1% (46.1%): Currently commanding the highest probability, 3.1% is heavily favored by the order book. Traders looking to back this outcome face a “Buy Yes” contract price of 46¢, signaling a high degree of market conviction. This contract alone has generated $27.6K in volume.

🥈 Tier 2: The Primary Challengers

• 3.2% (18.7%): Positioned as the most viable alternative, 3.2% maintains a 18.7% chance of resolving true. Its “Buy Yes” shares currently trade at 19¢.
• 3.0% (16.9%): Sitting in third place with a 16.9% probability, the market shows measured skepticism toward 3.0%, treating it as an outside wildcard unless momentum shifts.

🥉 Tier 3: The Long-Tail Options (Combining for ~18.3%)

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 3.3% (6.7%), 3.6% (3.5%), and ≤2.9% (3.1%).
• Speculative Volume: Despite low statistical likelihood, certain long-tail contracts like 3.4% are still attracting notable interest.

This Market will resolve according to the estimate of the World GDP growth rate (Real GDP, annual percent change) reported by the International Monetary Fund in the World Economic Outlook Update released between the October 2026 and April 2027 editions of the World Economic Outlook, expected to be released in January 2027.

The relevant figure may be found in the table titled “World Economic Outlook Growth Projections” under “Estimate” in the row “World Output” and the column “2026”. Changes in the IMF’s World Economic Outlook reporting format will not disqualify a published figure from counting.

The GDP release will be made available here: https://www.imf.org/en/publications/weo

If no estimate of the 2026 annual percent change in world real GDP is released in a World Economic Outlook Update between the October 2026 and April 2027 editions of the World Economic Outlook, this market will resolve according to the published figure for 2026 annual percent change in World real GDP in the April 2027 edition of the World Economic Outlook. If no such figure is published by April 30, 2027, 11:59 PM ET, another credible resolution source will be chosen.

If multiple World Economic Outlook Updates are released between the October 2026 and April 2027 editions of the World Economic Outlook, this market will resolve based on the first such publication which includes an estimate of the 2026 annual percent change in World GDP. Projections of World GDP, however, will not be considered.

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 release 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.

Note: the resolution source for this market reports annual percent change in world real GDP to one decimal point (e.g. 3.3%). Thus, this is the level of precision that will be used when resolving the market.

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 3.1% currently trades at 46.1%, but our AI places its Fair Value at just 34.5%. This creates a large negative EV Gap of -11.6%, suggesting the crowd may be overhyping this outcome and driving the premium too high.
• The Best Value Play (Highest EV) Our model identifies 3.7%+ as the premium value opportunity on the board. While the market only assigns it a 0.4% trading probability, our AI’s Fair Value assessment sits at 8.7% — yielding an impressive +8.3% EV Gap.
• Under-the-Radar Dark Horses Other notable discrepancies include 3.4% (EV Gap: +7.3%) and 3.6% (EV Gap: +2.5%). These long-tail opportunities are heavily discounted by the live order books despite stronger statistical backing from our predictive model.
