Prediction Pulse
AI Pulse Score Engine
At the core of the platform is the proprietary Pulse Score, an AI-driven probability engine that independently analyzes every single prediction market. It goes beyond simply reflecting current odds by calculating its own estimate of an event's true likelihood. This score is presented alongside market prices, instantly highlighting discrepancies and potential mispricings where the AI's conviction diverges from the crowd's, offering a quantifiable edge for deeper investigation.
Cross-Platform Market Aggregation
Prediction Pulse acts as a unified command center, pulling in and continuously updating thousands of live markets from major platforms like Polymarket and Manifold. This aggregation saves users from the tedious task of checking multiple sites, providing a single, comprehensive view of global prediction market activity. All data is refreshed every 15 minutes, ensuring you have access to the most current trading signals and market movements in one place.
Canonical Event Grouping
Instead of presenting a chaotic list of individual bets, the platform's AI intelligently groups related markets into canonical real-world events.

It provides a data-driven second opinion to validate or challenge their own theses before committing capital.
The Researcher Analyzing Collective Wisdom

Prediction Pulse FAQ
What is a Pulse Score?
The Pulse Score is Prediction Pulse's proprietary AI-generated probability for a given market outcome. While the market price reflects the current collective bet of traders, the Pulse Score represents the platform's AI model's independent assessment of the true likelihood of that outcome. The difference between the market's "YES" percentage and the AI's score highlights where the model sees a potential edge or mispricing.
Which prediction market platforms does Prediction Pulse aggregate?
Currently, Prediction Pulse aggregates and displays live markets from two major platforms: Polymarket and Manifold. The platform tracks tens of thousands of markets from these sources, updating odds, volume, and its AI scores every 15 minutes to provide a consolidated, real-time view of the prediction market ecosystem.
How does the AI determine its Pulse Score and verdict?
The AI model analyzes a wide array of data related to each market's event, though the exact proprietary methodology is not disclosed. It synthesizes available information to estimate a probability. The "Pulse verdict" (e.g., YES or NO) is the AI's called outcome based on its score, accompanied by a confidence level (e.g., 55/100) that indicates the strength of its conviction in that assessment.
What are "Edge Opportunities"?
"Edge Opportunities" are specific markets where Prediction Pulse's AI identifies a significant divergence between its Pulse Score and the current market price. These are highlighted in sections like "Top Edge Movers" and represent instances where the AI believes the crowd may be mistaken. A large point difference (e.g., -11 pts) suggests a potential mispricing that users can investigate for trading or analytical purposes.
