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 Anthropic currently trades at 89.5%, but our AI places its Fair Value at just 72.8%. This creates a large negative EV Gap of -16.7%, suggesting the crowd may be overhyping this outcome and driving the premium too high.
• The Best Value Play (Highest EV) Our model identifies OpenAI as the premium value opportunity on the board. While the market only assigns it a 10.5% trading probability, our AI’s Fair Value assessment sits at 27.2% — yielding an impressive +16.7% EV Gap.
