Prediction Market Guides

Start with the fundamentals or go deeper. Every guide is written by traders with real money on the line.

Key takeaways

  • • Prediction markets let you buy and sell contracts that pay out if an event happens (YES) or doesn't (NO).
  • • Contract prices represent implied probabilities — a $0.65 price means a 65% chance of "yes."
  • • In the US, Kalshi is the only CFTC-regulated platform. Globally, Polymarket has the most liquidity.
  • • Research consistently shows prediction markets outperform expert polls and media pundits on accuracy.
  • • You can start with as little as $1 on most platforms.

What Is a Prediction Market?

A prediction market is a marketplace where participants buy and sell contracts on the outcome of future events. Think of it like a stock market — but instead of trading shares of companies, you trade on whether specific events will happen.

Each contract settles to $1.00 if the underlying event occurs ("YES") or $0.00 if it doesn't ("NO"). The price at any moment represents the market's consensus probability.

Worked example

Kalshi market: "Will the Fed cut rates by June 2026?"

  • • Contract trades at $0.71
  • • Implies a 71% probability of a rate cut
  • • Buy 100 YES shares at $0.71 each → spend $71
  • • If Fed cuts: receive $100, profit = $29
  • • If Fed holds: your $71 is lost

Why Are Prediction Markets So Accurate?

Prediction markets aggregate information from thousands of participants, each with their own research and analysis. Traders who are consistently wrong lose money; those who are right profit. This financial incentive creates the "wisdom of crowds" — where collective judgment of many self-interested participants often outperforms any individual expert.

"Prediction markets aggregate information in a way that no individual expert can replicate. The price is the forecast." — Paul Tetlock, author of Superforecasting

Risks to Understand

  • • You can lose your entire stake. If you bet YES and the event doesn't happen, you lose 100% of that position.
  • • Liquidity risk. On smaller markets, you may not be able to exit at a favorable price.
  • • Platform risk. Offshore platforms carry counterparty risk. Prefer regulated venues for larger amounts.
  • • Resolution disputes. Read the fine print on each contract.
