The P2P exchange model
No house edge — you set the price
Both Novig and ProphetX eliminate the bookmaker's built-in margin by matching bettors directly against each other. At a traditional sportsbook like DraftKings or FanDuel, the house sets odds at -110/-110 on a coin-flip market, keeping ~4.5% regardless of outcome. On a P2P exchange, you post a limit order at the price you want — say, -105 on the Chiefs — and wait for another user to take the other side. If matched, neither side pays a sportsbook margin.
Post prices, get filled, or take the spread
Both platforms use limit orderbooks. You can be a maker — posting an order at your price and waiting — or a taker, accepting an existing price in the book. Makers add liquidity to the exchange; takers remove it. On ProphetX, the small exchange fee typically applies to matched volume. On Novig, there is currently no commission either way. Understanding the orderbook is essential: the best prices require patience as a maker.
Cost to trade
Commission-free
As of April 2026, Novig charges no trading commission. This is a significant advantage over traditional sportsbooks, which embed a 4–8% vig into every market. A bettor placing $10,000 in monthly volume at a typical sportsbook pays $400–$800 in implicit fees. On Novig, that same volume costs nothing in commission. Novig monetizes through other means — check novig.us for any updates to the fee structure, as commission-free can change.
Small exchange fee on matched volume
ProphetX charges a small exchange fee on matched volume — similar in concept to how stock exchanges charge a fraction of a cent per share traded. The exact rate is available on prophetx.com. Even with this fee, ProphetX is significantly cheaper than traditional sportsbooks. The fee model is transparent: you know your cost before you post an order. For high-volume sharp bettors, even a small fee per matched dollar compounds across thousands of bets.
The real cost comparison
A traditional sportsbook pricing a game at -110/-110 embeds a ~4.5% margin per side. On $1,000 wagered, you pay ~$45 in implicit fees. Novig at commission-free: $0. ProphetX at a small exchange fee: a few dollars at most. Both platforms represent a massive cost reduction over any traditional US sportsbook. The debate between Novig and ProphetX on fees is a rounding error compared to the savings vs DraftKings or FanDuel.
Market depth and fill rates
Series B — fastest-growing US sports exchange
Novig raised a Series B, reflecting significant investor confidence and user growth. Its 35+ state availability gives it the broadest possible US addressable market. Liquidity is strongest on NFL, NBA, and major MLB games. College sports are available — a differentiator vs ProphetX. Peak liquidity is in the hours before major games; thinner in off-peak periods. As user base grows, fill rates on limit orders improve.
Established since 2021 — core exchange community
ProphetX has been operating since 2021, giving it a longer track record and a community of exchange-focused sports traders. Its user base skews toward experienced bettors who understand the limit orderbook model. Liquidity is concentrated in the major four US pro leagues. The platform's older user base may provide more consistent fill rates on specific markets vs newer exchanges, but Novig's faster growth is closing the gap.
Where you can trade
35+ US states
Novig has secured access in over 35 US states — more than any comparable sports exchange. This wide footprint is a major competitive advantage: it means more potential trading counterparties and broader liquidity. Novig is actively expanding state availability. Check novig.us for the current list, as new states are added regularly.
Legal sports betting states
ProphetX operates in US states with legal sports betting. As of 2026, over 30 states have legal sports betting, so ProphetX is available to the majority of US sports bettors. However, if you are in a state where sports betting is not yet legal, ProphetX will not be accessible. Check prophetx.com for their current state list.
Both platforms are actively expanding. State availability is one of the fastest-changing aspects of the US sports exchange market — verify directly with each platform for your specific state.
No account limits — ever
You will never be limited or banned for winning
Both Novig and ProphetX are designed for bettors who have an edge. Unlike traditional sportsbooks — which routinely limit winning accounts to $20 or $50 max bets — P2P exchanges have no house to protect. Your counterparty on the exchange is another bettor who has agreed to your price. Winning consistently does not trigger limits, restrictions, or account closures. For serious sports bettors who have been limited at DraftKings, FanDuel, or other books, exchanges like Novig and ProphetX are the long-term home. You set prices, post limits, and get filled at fair market rates.
Common questions
What is a sports prediction market exchange? +
A sports prediction market exchange is a peer-to-peer platform where bettors trade directly with each other rather than against the house. There is no bookmaker embedding a margin into prices. You can post limit orders at your desired price and wait for another user to match you — similar to how a stock exchange works. This structure eliminates the vig that traditional sportsbooks charge.
Is Novig truly commission-free? +
As of April 2026, Novig does not charge a trading commission — the platform makes money through other revenue streams. This can change as the company's business model evolves. Check novig.us for the current fee schedule before trading a large position.
Do Novig and ProphetX have live betting? +
Both platforms offer in-game and live markets on major sports. Liquidity on live markets is generally lower than on pre-game markets for both platforms — this is typical of P2P exchanges, where the orderbook depends on other users also wanting to trade the live line. Pre-game markets on popular NFL and NBA games have the best liquidity on both platforms.
Can I use both Novig and ProphetX? +
Yes. Many sharp sports bettors use multiple exchanges to get the best available price. Because Novig and ProphetX have different user bases and different liquidity profiles, a price that is unavailable or thin on one platform may be available on the other. Using both platforms to shop lines is a standard approach among serious sports traders.
Are sports prediction market exchanges legal in my state? +
Legality depends on your state. Both Novig and ProphetX operate under US law in the states where they hold licences. Novig is currently available in 35+ states. ProphetX is available in US states with legal sports betting. Check novig.us and prophetx.com for their current state availability lists, as licensing is actively expanding.
