Sports are now the single most-traded category in prediction markets. The key difference from a sportsbook is structural: on a prediction market you trade contracts against other people at prices that move with the market, rather than betting against the house at fixed odds. That means no built-in bookmaker margin on a true exchange, and the ability to sell out of a position before the final whistle.
Here is what you can trade in the sports category, where to do it, how exchange pricing compares with a sportsbook, and how to trade it well.
What you can trade
- Game winners — the probability of each side winning a single game or match.
- Spreads and totals — outcomes expressed as event contracts (will the margin or total be above or below a line).
- Player props — whether a player hits a statistical threshold.
- Futures — season-long markets such as champions, division winners, win totals and award winners.
- Tournaments — outright winners and round-by-round progress in events and competitions.

Exchange pricing vs a sportsbook
On a prediction market the price is a probability: a team at 60¢ implies a 60% chance, and the contract settles at $1 or $0 on the official result. Because a no-vig exchange like Novig or ProphetX matches you against other traders rather than a bookmaker, there is no margin baked into the line — which can mean better effective pricing on liquid games than a sportsbook offers. You can also usually close a position mid-event rather than waiting for it to settle.

Tips for trading sports markets
- Shop for price. The same game can trade differently across venues; the no-vig exchanges are often cheapest on liquid markets.
- Follow the liquidity. Pricing is tightest on marquee events; obscure markets can be thin.
- Check state rules. Sports event contracts face pushback in some states — confirm availability where you are.
- Manage in-play risk. Live markets move fast; decide your exit before you enter.

How are sports markets different from a sportsbook?
Instead of betting against the house at fixed odds, you trade contracts against other users at prices that move with the market. On a no-vig exchange there is no bookmaker margin, and you can often sell before the event ends.
Are sports prediction markets legal?
They are offered by CFTC-regulated platforms, but some states have pushed back specifically on sports contracts and the position is still evolving. Always check current availability in your state.
Can I trade live, in-play markets?
Many platforms offer in-play markets that move quickly as a game unfolds. They can be an opportunity but carry added risk, so set your exit plan before entering.
