How Prediction Markets Work

Learn how real-money prediction markets forecast the future better than polls and expert opinions

What Are Prediction Markets?

Financial markets where people bet real money on future events, creating crowd-sourced probability forecasts

Prediction markets are trading platforms where the price of a contract represents the probability of an event happening. If a market shows 70%, traders collectively believe there's a 70% chance that outcome will occur.

Unlike polls or expert predictions, these markets involve real money. Traders profit when they're right and lose when they're wrong, creating powerful incentives for accuracy. This "skin in the game" makes prediction markets remarkably accurate at forecasting future events.

Example:

"Will Dave Portnoy give a 9+ pizza review in 2025?" trading at 78% means the market believes there's a 78% chance this will happen. As new information emerges (like Portnoy announcing a pizza tour), the price adjusts in real-time.

How Market Prices Work

High Probability (70-90%)

Market believes the outcome is very likely to happen. Buying "Yes" shares is expensive but safer. Buying "No" shares is cheap but risky.

Toss-Up (40-60%)

Market is uncertain about the outcome. Prices near 50% indicate the crowd sees it as a coin flip, with new information able to swing the market significantly.

Low Probability (10-30%)

Market believes the outcome is unlikely. Buying "Yes" shares is cheap but risky. Buying "No" shares is expensive but safer.

Price = Probability

A market at 65% means "Yes" shares cost $0.65 and pay $1.00 if correct. If the event happens, you profit $0.35 per share (54% return). If not, you lose your $0.65.

Why Prediction Markets Are Accurate

Real Money Creates Accountability

When your own money is at risk, you think harder and do more research. Traders who make accurate predictions profit, while those who guess poorly lose money. This creates a natural selection process where informed traders dominate.

Crowd Wisdom Beats Experts

Thousands of traders bring different information, perspectives, and expertise. While any single person can be wrong, the aggregate wisdom of the crowd tends to be remarkably accurate. Polymarket processed over $9 billion in trading volume in 2024, reflecting this collective intelligence.

Real-Time Information Integration

Prices adjust instantly as news breaks. When Dave Portnoy announces a pizza tour, relevant markets update within seconds. This responsiveness makes prediction markets leading indicators, often moving before traditional media catches on.

Proven Track Record

Prediction markets accurately forecasted the 2024 US presidential election when traditional polls failed. They've also correctly predicted Supreme Court decisions, Oscar winners, and major geopolitical events with higher accuracy than expert panels.

Example: Pizza Review Market

Market: "Will Dave Portnoy give another 9+ pizza review in 2025?"

Current Price: 78% (Yes shares cost $0.78, No shares cost $0.22)

Your Analysis: You believe Portnoy is planning a nationwide pizza tour and will definitely find at least one exceptional pizza. You think 78% is too low - it should be closer to 90%.

Action: You buy 100 "Yes" shares at $0.78 each, spending $78 total.

Outcome 1: Portnoy gives a 9.2 rating to a Detroit pizza in August. Market resolves "Yes". Your shares pay $1.00 each. Total: $100. Profit: $22 (28% return).

Outcome 2: Portnoy's highest rating in 2025 is 8.9. Market resolves "No". Your shares become worthless. Loss: $78 (100% of investment).
