Prediction markets have become the hottest topic among sports fans in the past few years as they have exploded in popularity, and nowhere is this more true than in the NFL. There are now millions of dollars placed on the NFL, from individual games to Conference Champions and all the way to the Super Bowl.
But prediction markets are not the same as sports betting, and they’re not constrained by the laws that sports betting must adhere to, meaning they are widely available across the United States. The two largest prediction markets both offer benefits and drawbacks, and the decision of Kalshi vs Polymarket is one that all users must make, but first they need to understand how prediction markets work and how to use them to enjoy the NFL.
How do prediction markets work?
Instead of placing a traditional wager against a sportsbook’s set lines, prediction market users buy and sell binary event contracts. Each contract asks a clear “Yes” or “No” question, such as whether a team will win a Sunday matchup, capture a division title, or whether a player will earn the MVP award.
Contracts trade at prices ranging between 1¢ and 99¢, directly reflecting the crowd’s estimated probability of the event happening. For instance, if a “Yes” share on an NFL team winning is trading at 65¢, the market calculates a 65 percent chance of victory.
If the team wins, the contract settles at $1.00, yielding a 35¢ profit per share. If they lose, the contract expires at $0. Crucially, because trades take place on an open peer-to-peer exchange, participants do not have to hold positions until the game ends. Traders can buy or sell shares at any point to lock in profits or cap losses as game events unfold.
All the major prediction markets offer a wide variety of potential markets to trade on, and instead of betting against the house like a traditional sportsbook, you trade outcomes with fellow customers.
Why are prediction markets so perfect for the NFL?
The NFL’s weekly rhythm, stoppage-heavy games, and stat-driven fanbase make it an ideal fit for prediction markets. Unlike traditional sportsbooks that charge a built-in house commission (known as “vig”), prediction markets connect buyers and sellers directly, resulting in cleaner pricing and lower transaction costs.
Real-time price discovery thrives on the flow of an NFL game. Every touchdown, red-zone interception, or key injury instantly moves the contract price. A fan watching a game can buy shares on a team during a slow start, ride a second-quarter comeback, and cash out before halftime even finishes.
Furthermore, prediction markets give fans in states without legalized sports betting a compliant way to participate in event trading. By combining real-time liquidity, flexible hedging, and sharp market pricing, prediction markets offer football fans an active, interactive way to test their instincts throughout the season.
