AI Valuation Analysis: Finding Market Mispricings & EV Gaps

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 December 31 currently trades at 4.5%, but our AI places its Fair Value at just 1%. This creates a large negative EV Gap of -3.5%, suggesting the crowd may be overhyping this outcome and driving the premium too high.

Frequently Asked Questions

What is the current market consensus on "Will the US confirm that aliens exist by...?"?

As of the latest update, December 31 leads the field as the frontrunner with a 4.5% win probability, followed by September 30 at 2.2%. Total trading volume for this pool has reached $64.6M, indicating deep liquidity and high trader engagement.

How does the AI Fair Value differ from the live Market Trade Value?

The live Market Trade Value reflects public sentiment, order-book momentum and speculative capital. Our AI Fair Value is computed independently with quantitative models that strip out hype to focus on underlying data. When the two diverge, it creates an EV Gap, flagging where the market may be mispricing an outcome.

Is the market consensus overreacting to any specific outcome?

Yes — our data suggests a notable overreaction around December 31. The crowd has pushed its live Trade Value up to 4.5%, yet our Fair Value assessment puts its real likelihood at just 1%, a negative EV Gap of -3.5% that signals the contract is overpriced.
