- An NFL contract is a $1 Yes/No share on an outcome such as a game winner, priced from 1¢ to 99¢. A winning share pays $1.
- The price is the market's implied probability, not a forecast that the result will happen. A 64¢ favourite still loses about one game in three.
- On a 64¢ contract, Kalshi's standard taker fee adds about 1.6¢ per contract. Compare the all-in price with a sportsbook line before you trade.
- The NFL opposes some contracts, such as injuries and officiating, and sports contracts are blocked or challenged in several states.
NFL prediction markets turn football results into tradeable shares. Instead of taking a sportsbook's line, you buy "Yes" or "No" on an outcome, for example Will the Chiefs win on Sunday?, from other traders. The share pays $1 if you are right, so its price is the market's implied probability. This page explains how NFL contracts work, what they cost after fees, how they settle in odd situations, what the NFL itself says, and where they are legal. It is part of our sports event contracts guide, and the sportsbook side of the same sport is in NFL betting.
How NFL prediction market contracts work
Every contract is a simple question with a $1 payout. If "Yes, the Chiefs beat the Bills" trades at 64¢, the market rates the Chiefs at about a 64% chance. Buy at 64¢ and you make 36¢ per share if they win, before fees. If they lose, you lose your 64¢.
Two things make this different from a bet slip:
- You can sell at any time. If your team goes ahead, the price rises and you can sell to lock in a profit before the final whistle. If it goes against you, you can sell to limit the loss.
- You trade with people, not the house. There is no margin built into the odds, but there are trading fees and a gap between the best buy and sell price.

NFL contract types
| Contract type | Example | Typical availability |
|---|---|---|
| Game winner | "Will the Eagles beat the Jaguars?" | All sports platforms |
| Spread | "Will the Bills win by more than 6.5?" | Kalshi, Polymarket, Novig, ProphetX, sportsbook-style apps |
| Total | "Will the game have more than 47.5 points?" | Same as spreads |
| Player props | "Will Josh Allen throw for 250+ yards?" | Kalshi, Novig, ProphetX and others |
| Combos (parlays) | Several outcomes in one contract | Kalshi, Novig, ProphetX, FanDuel Predicts, DraftKings Predictions |
| Futures | Super Bowl LXI winner, MVP, conference champions | Most platforms |
| Live trading | Prices update during the game | Kalshi, Polymarket, Novig and others |
Examples are illustrative, not live markets. Menus change by platform and by state, and the NFL schedule drives them: markets open for each game during the week, and futures stay open all season through Super Bowl LXI on 14 February 2027.[1]
A worked example: what a trade really costs
Say you buy 50 "Chiefs win" contracts at 64¢ on Kalshi, as a taker.
| Item | Amount |
|---|---|
| Cost of 50 contracts at 64¢ | $32.00 |
| Taker fee (0.07 × 50 × 0.64 × 0.36, rounded up) | about $0.81 |
| Total cost | about $32.81 |
| Payout if the Chiefs win | $50.00 |
| Profit if they win | about $17.19 |
| Loss if they lose | about $32.81 |
Your all-in price is about 65.6¢ per contract, so the real implied chance you are paying for is a little above the 64% on the screen. Polymarket US charges a very similar taker fee.[4][5] Resting limit orders are often cheaper: on Kalshi they are often free, and on Polymarket US they can earn a small rebate. Work out your own numbers with our fee calculator.
NFL prediction market prices vs sportsbook odds
To compare, divide 1 by the price: a 64¢ contract is about 1.56 in decimal odds before fees, or about −178 in American odds. A sportsbook moneyline of −180 implies 64.3%, but that figure still includes the book's margin. Our price to odds converter and the contract vs sportsbook odds calculator do the conversion both ways.
| Where you buy | Price per $1 payout | Implied chance | Comment |
|---|---|---|---|
| Sportsbook spread at −110 | 52.4¢ | 52.4% | Margin built in |
| Exchange at 51¢, resting limit order (no taker fee) | 51.0¢ | 51.0% | Cheaper than −110, if your order fills |
| Exchange at 51¢, taker on Kalshi | about 52.75¢ | about 52.75% | Slightly dearer than −110 |
| Sportsbook-style prediction app at 51¢ | about 53¢ | about 53% | Fee is about 2% of the payout |
So prediction markets are not automatically cheaper. They tend to win on resting limit orders and on pre-game spreads, and lose when you cross the spread as a taker or pay a flat fee. For the full comparison read prediction markets vs sportsbooks. If you would rather bet the traditional way, see NFL betting.
Liquidity, spreads and exiting early
Liquidity. NFL game winners, spreads and totals on Kalshi are among its deepest sports markets, and spreads can be 1¢ wide. Player props and later-week games are thinner, and a market order can fill at a worse price than you expect. Use limit orders and read prediction market liquidity before you trade a thin market.
Exiting early. Selling before the game ends is the biggest practical difference from a sportsbook. You sell to another trader at the best bid, so the price you get depends on liquidity, and you pay a fee on the sale too. During a game the bid can vanish for a moment after a big play.
How NFL contracts settle: rules to read first
Every contract has its own rulebook, with a named source, that decides what happens in odd situations. The table shows what to look for, not what every platform does.
| Situation | What to check in the contract rules |
|---|---|
| Game goes to overtime | Whether the winner includes overtime (game winners normally do) |
| Game ends in a tie | The stated payout; some contracts split or refund |
| Postponed or suspended game | The deadline to complete the game and the fallback settlement |
| Player prop, player inactive | Whether the contract is voided, or settles at No |
| Stat correction after the game | Which source settles it, and when the result becomes final |
| Spread or total ties the number | Whether the market has a half-point or can settle at a push price |
Read the rules on the market page before every trade, and see prediction market resolution for how settlement and disputes work.
What the NFL says about prediction markets
The league is a critic. In letters to Kalshi and Polymarket it has asked operators to stop listing contracts it sees as manipulable, including contracts on injuries, officiating decisions and what broadcasters say.[3] In October 2026 the NFL also filed a brief urging the US Supreme Court to hear a dispute between New Jersey regulators and Kalshi, backing the state's call for state-level regulation.[2] Kalshi has said it is committed to game integrity and points to its partnerships with other leagues, and Polymarket has said it shares the league's integrity goals.[2]
This matters to you in two ways. Some contract types may disappear without warning, and the legal ground under NFL contracts is still moving. For how sportsbooks have responded, see sportsbooks injury refunds.
Are NFL prediction markets legal?
Kalshi and Polymarket US are regulated by the CFTC, so your money sits with a federally supervised exchange. But many states say sports contracts are unlicensed betting. In October 2026 they were blocked in Nevada and Michigan, Ohio ordered platforms to stop, and cases were running in other states.[6] Platforms use your location to hide markets you cannot trade. Rules change almost weekly, so check are prediction markets legal and our state tracker for sports contracts before you deposit. Age limits are 18+ on most platforms and 21+ on some.

Tips for trading NFL contracts
These are habits that reduce mistakes, not a way to guarantee profit.
- Treat the price as an estimate. 64¢ is not a prediction that the team will win.
- Count the all-in cost. Add the fee and the spread, then compare with a sportsbook.
- Use limit orders unless you must trade now. See order books and limit orders.
- Read the rules for overtime, ties and postponements before you trade, not after.
- Watch injury news. Prices can move sharply on a quarterback update, and thin markets move most.
- Keep stakes small. Position limits apply, and football results are noisy.
- Set a weekly budget and stick to it, as you would with any bet.

FAQ: nfl prediction markets
How do NFL prediction markets work?
You buy a $1 contract on an outcome, for example "Will the Chiefs win?", from another trader. The price in cents is the market's implied probability. If the outcome happens the contract pays $1, if not it pays nothing, and you can usually sell before the game ends.
Is a 64¢ price a 64% chance?
It is the market's implied probability, before fees. It is an estimate set by traders, not a certain forecast, and fees and the gap between buy and sell prices mean your real cost is a little higher.
Which platforms offer NFL contracts?
Kalshi has the deepest NFL markets. Novig, ProphetX, Robinhood, Crypto.com, FanDuel Predicts and DraftKings Predictions also list NFL contracts, and Polymarket US lists sports. Menus and states differ, so check each app.
What happens to a contract if the game goes to overtime or ends in a tie?
It depends on the contract's own rules. Game-winner contracts normally count overtime, and the rulebook says what happens on a tie. Read the rules link on the market before you trade.
What happens if a game is postponed?
Each contract states a rule, usually a deadline by which the game must be played, after which the market settles under a stated fallback such as refunding at a set price. The rules are on the contract page.
Are NFL prediction markets legal?
Kalshi and Polymarket US are regulated by the CFTC, but states argue sports contracts are unlicensed betting. In October 2026 they were blocked in Nevada and Michigan and challenged elsewhere. The NFL has also urged the Supreme Court to hear a case against Kalshi.
Are prediction markets cheaper than sportsbooks for the NFL?
Sometimes. A resting limit order on Kalshi or a pre-game trade on Novig can beat a −110 line, but a taker order plus fees can cost more. Always compare the total price.
