How Novig prices work
Novig is a peer-to-peer sports prediction market regulated by the CFTC. You do not bet into a bookmaker's line; you trade against other users at the price the market sets. A pre-game straight trade taken in the Novig app or on the web carries no fee under Novig's fee schedule, and our tools price it that way: the number you see is the number you pay. That is why Novig so often shows up near the top of our line-shopping boards.
Our boards list Novig prices in American odds, the same format as every sportsbook we track. A contract price works too: 60 cents and -150 are the same 60% price. Switch the input above between American odds, cents and percent and every format converts both ways.
Novig odds examples
Pre-game prices at Novig, where no fee applies, so the odds after fees equal the posted odds and the break-even rate equals the implied probability.
| Price | Implied | American | Decimal | Fractional | American after Novig fee | Break-even after fee |
|---|---|---|---|---|---|---|
| 10¢ | 10% | +900 | 10.000 | 9/1 | +900 | 10% |
| 25¢ | 25% | +300 | 4.000 | 3/1 | +300 | 25% |
| 38¢ | 38% | +163.16 | 2.632 | 31/19 | +163.16 | 38% |
| 50¢ | 50% | +100 | 2.000 | 1/1 | +100 | 50% |
| 62¢ | 62% | -163.16 | 1.613 | 19/31 | -163.16 | 62% |
| 75¢ | 75% | -300 | 1.333 | 1/3 | -300 | 75% |
| 90¢ | 90% | -900 | 1.111 | 1/9 | -900 | 90% |
Example: -150 on Novig is a 60% price (1.667 decimal, 2/3 fractional). With no fee you need to win 60% of the time to break even.
Finding the no-vig price of a Novig market
Many people searching for a Novig calculator want the fair price of both sides. Enter both prices in the fair price panel: the calculator adds the two implied probabilities, shows how far they run over 100%, and scales each side back so the pair adds to exactly 100%. For a sportsbook line the overage is the vig; on Novig it is mostly the gap between the best offers on each side. For a full sportsbook devig use the no-vig calculator.
Novig fees on live and futures trades
Novig publishes a taker fee on live trades and futures (maker fills are free). Our tools do not net those fees into a price yet, so pick Live or Futures above and the calculator shows the price before fees and says the fee is not mapped, instead of guessing. Novig's published schedule is listed on our Novig promo code page.
Compare Novig with Kalshi and the books
The same calculator handles Kalshi, Polymarket US and ProphetX fees, so you can line up one price across venues. The prediction market odds converter walks through the cents to American odds math, and line shopping shows Novig's price next to every book we track.
21+. Novig sets its own eligibility, availability and fees; confirm them in the app before you deposit.
