How to Get Your Piece of the $1 Trillion Prediction Market Pie

Prediction markets have existed for decades. Until recently, they were a niche tool used by academics and professional traders. That changed fast.

Trading volume on Polymarket and Kalshi jumped from $500 million to $6 billion between June 2025 and January 2026, while the broader crypto market was contracting. Polymarket app downloads grew from 30,000 to over 400,000. Kalshi went from 80,000 to 1.3 million. Binance downloads fell by more than half.

Users are not just switching apps. They are switching categories. Kalshi alone added over 1.2 million users in seven months. Operators like Underdog have already restructured their product toward prediction markets in direct response.

The closest comparison is the sweepstakes casino wave of 2024 and 2025: a product category that outpaced regulation, created real revenue early, and rewarded operators who moved first. Prediction markets are in that position today.

This guide covers what prediction markets are, how they work, how to enter legally, what compliance requires, and how the revenue model actually works.

What are Prediction Markets

Prediction markets are platforms that let anonymous users gamble on uncertainty and place “predictions” rather than bets.

The events can be anything. These might be the outcome of elections in any country, the passing of laws, referendums, the resignation of politicians, the results of sports matches, inflation rates, hurricanes, release dates for TV shows, epidemics, wars, and even the existence of aliens and their upcoming visit to Earth. This is a new “stock market for trends” that is evolving in the “attention economy”.
