Prediction markets vs sports betting
They scratch the same itch, putting money on an outcome, but they work differently. A sportsbook sets a line and takes the other side, keeping a margin. A prediction market is an exchange where you trade contracts against other users at a price that reflects the real probability, and you can trade back out before the game ends. Here is how that changes cost, access, and flexibility.
Side by side
*Federally regulated exchanges have reached states without sportsbooks, but their sports contracts face legal challenges in some states. Confirm availability for your location.
Cost: exchange fee vs vig
This is the biggest practical difference. A sportsbook’s -110 line on each side implies about a 4.5% hold the house keeps regardless of outcome. A prediction-market exchange charges only a thin per-trade fee because you trade against other users, so the price tracks the genuine probability rather than a margin. Over a season, that gap is the single biggest driver of net results. See it quantified in Kalshi vs the sportsbooks.
Flexibility: hold a position, not a ticket
A sportsbook bet is a fixed-odds ticket settled at the final result, with an optional cash-out the book prices for you. On a prediction market you hold a position you can sell back into the market at any time as the price moves, taking profit early or cutting a loss on your terms. It behaves more like trading than betting. New to it? Start with what prediction markets are.
Which should you use for the NFL?
If you want same-game parlays, big promos, and a familiar betting feel in a licensed state, a sportsbook delivers that. If you care about price, the freedom to trade in and out, or access from a state with no legal book, a prediction market is the stronger fit.

Frequently asked
What is the difference between prediction markets and sports betting?
In sports betting you place a fixed-odds bet against the house, which keeps a margin (the vig). On a prediction market you trade event contracts against other users at a price that reflects the implied probability, pay only a thin exchange fee, and can sell your position before the event ends.
Are prediction markets cheaper than sportsbooks?
Usually. A sportsbook's standard -110 pricing carries roughly a 4.5% hold, while a prediction-market exchange like Kalshi charges only a thin per-trade fee. Lower cost means a better effective price on most NFL markets.
Are prediction markets legal where sports betting isn't?
Often, yes. Federally regulated exchanges like Kalshi are overseen by the CFTC rather than state gaming boards, so they have operated in states without legal mobile sportsbooks. Their sports contracts are being challenged in some states in 2026, so confirm availability for your location.
Is a prediction market just gambling with extra steps?
They overlap, but the mechanics differ: you trade a position you can exit at a market price rather than holding a fixed-odds ticket. We dig into where the line sits in our guide on whether prediction markets are gambling.
