By Kalshi Jan 6, 2026 Prediction markets are exploding in popularity. This is thanks in no small part to Kalshi’s judicial win against regulators from the Commodity Futures Trading Commission (CFTC) in October 2024. This case represented a monumental milestone, as it legalized election trading in the US. 2025 was arguably an even more important year for the industry, as prediction market platforms quickly moved from the financial fringe into the mainstream. Kalshi was even featured in an episode of South Park . Yet despite the soaring popularity of these platforms, many people are still left wondering: what exactly is a prediction market? The following article provides a detailed explanation of this burgeoning asset class, and how you can legally trade on anything from sports predictions to culture to weather, just like you would on the stock market. What is a prediction market? Prediction markets, sometimes referred to as event contracts, derivatives, idea futures, information markets and more, have actually been around for centuries. They offer the public an opportunity to buy shares to trade on real-world outcomes, from presidential elections to polls to Trump speeches, to crypto prices and sports outcomes. Although they are sometimes referred to as "political betting," and compared to gambling platforms and sportsbooks, there are important differences. In reality, they have much more in common with futures trading or trading in the stock market than they do with traditional sportsbooks.

Definition and components Prediction markets are arranged as binary, multiple-selection, continuous and conditional markets, and the operating mechanics are quite simple. Here’s an example of a standard binary prediction market, which can be applied to presidential elections, sports, politics, weather forecasts, cultural events and many other outcomes: Will the United States experience another government shutdown on January 31, 2026? Kalshi’s traders, where total contract volume exceeds $500,000, currently predict a 30% likelihood for “Yes.” This means that a trader could buy a “Yes” share for 30 cents and get paid out $1 if the event occurs. Conversely, if the government does not shut down (with “No” displaying a 70% probability), a trader would need to buy a 70-cent contract on “No” to earn that same $1 payout.
