What does the crowd believe? Polymarket is the world's largest prediction market platform, where traders stake real money on the outcomes of global events. Unlike polls or analyst forecasts, these markets carry skin-in-the-game — each probability reflects the collective judgment of thousands of participants who stand to gain or lose based on the accuracy of their views.

How Prediction Markets Work

A prediction market is a contract that pays $1 if a specific event occurs, and $0 if it doesn't. If a contract trades at $0.72, the market implies a 72% probability of that outcome happening. The price is set by supply and demand: when more traders believe an event will occur, they buy the "Yes" contract, pushing the probability higher. This mechanism makes prediction markets one of the most reliable real-time probability aggregators available — often more accurate than expert panels or traditional surveys.

How to Read the Tables

Each row shows one active market. Yes Prob. is the current market-implied probability of the stated event occurring. No Prob. is the inverse (100% minus Yes). The Signal column classifies confidence: High confidence (≥65%) means the crowd has reached strong consensus; Uncertain (40–64%) means the outcome is genuinely open; Unlikely (<40%) means the crowd has largely ruled the event out. Volume indicates total money traded — higher volume means more reliable pricing. The small badge (e.g. +3.5pp 24h) shows how the probability shifted in the last 24 hours.

Geopolitics & Policy

Political risk is notoriously hard to quantify — prediction markets are one of the few tools that translate it into actionable probabilities. The markets below track election outcomes, trade policy shifts, and geopolitical flashpoints. High-probability outcomes (≥65%) indicate crowd consensus; markets clustered near 50% signal contested terrain where a single headline can swing sentiment significantly.
