How Does Novig Work? Peer-To-Peer Sports Trading - And Only Sports
How does Novig work? You place an order into a peer-to-peer order book and get matched against another user, not against a house. That is the whole core of it: Novig is a sports prediction market where every trade needs a real person on the other side, and the app's job is matching orders rather than setting lines against you. Simple as that sounds, the two things most reviews get wrong are what you can actually trade there and what you are actually signing up for today. Both answers are below, and both are more interesting than the marketing.
The Quick Answer
Novig matches your order against another user in a sports-only order book, so there is no house taking the other side of your trade. It currently runs as a dual-currency sweepstakes product while its CFTC-approved regulated exchange is still being built out. The full mechanic, the sports-only catalog, and the mid-transition fine print are below.
You Trade Against Other People, Not A House
A sportsbook posts a line and takes your bet itself. Novig does neither, and the difference runs deeper than branding — an exchange is not a sportsbook. It runs an order book, which is just a public list of orders: what people are willing to pay, and what people are asking. You can take a price someone else posted, or post your own and wait for a user to take it. When two orders meet, the trade happens. The platform is the referee, not your opponent.
The first thing that trips up sportsbook users is the prices. Novig quotes probabilities, not American odds. A contract does not read -150 or +170; it reads as a price between 0 and 1, and that price is the market's implied chance the outcome happens. A contract trading at 0.60 implies a 60% chance. If you want the translation habit anyway, our guide to converting contract prices into American odds covers it in two minutes.
Settlement is just as binary. Every contract settles at $1 if the outcome happens and $0 if it does not, and your profit is the gap between your entry price and where it settles. There is no middle ground and no pushed bet: the market resolves to one end or the other.
The second thing is a quirk of binary markets that makes books look emptier than they are. Every market has two sides, Yes and No, and the two are the same instrument viewed from opposite ends. A bid to buy Yes at 0.60 (a 60% implied chance) is exactly an offer to sell No at 0.40 (a 40% implied chance), because the two prices must add up to 1. So a screen that shows no offers on your side is not necessarily a dead market. The liquidity may simply be resting on the other side, where it counts just the same.
Hold onto that "prices are probabilities" idea. It comes back when we get to what trading here costs. First, watch the mechanic run once from start to finish.
A Worked Example: One Order, Start To Finish
Take a WNBA moneyline market where the home team's Yes contract last traded at 62 cents, meaning the crowd of traders puts the home side at about a 62% chance. Here is the full life of one order. (Prices here are illustrative of the mechanic, not live quotes.)
| Step | What happens |
|---|---|
| 1. You Post | You bid 62 cents for one Yes contract on the home team. |
| 2. The Book Shows It | Your bid appears to everyone else as an offer to sell No at 38 cents, because the two sides always sum to $1. |
| 3. Someone Matches | Another user takes the other side. You now hold Yes at 62 cents; they hold No at 38 cents. Novig matched you; it holds nothing. |
| 4. The Game Ends | Home team wins: your contract settles at $1 and you make 38 cents per contract. Home team loses: it settles at $0 and you lose your 62 cents. |
Notice the platform's role in that table: it appears exactly once, as the matchmaker in step 3. The whole trade is you against one other person, from post to settlement, and the price you agreed on is the probability you both signed up for. Now scale that mechanic across everything the app lists, and the natural question becomes what, exactly, it lists.
Sports Only: No Elections, No Weather, No Fed
Here is the fact that surprises almost everyone arriving from Kalshi or Polymarket coverage: Novig is sports only. "Prediction market" usually implies you can trade elections, the weather, or the next Fed decision. On Novig you cannot trade any of them. Not politics, not economics, not crypto prices, not temperature. It has never listed a non-sports market.
The one fact to take from this page: Novig is a sports-only exchange. No elections, no economics, no weather, no crypto — eight sports leagues and nothing else in its entire market history.
When we pulled Novig's full market catalog on August 4, 2026, its entire market history covered eight leagues: ATP and WTA tennis, MLB, MLS, the NFL, the PGA Tour, UFC, and the WNBA. Zero non-sports markets, ever. The league rail on the live site showed the same picture the same day. This is not a temporary gap while other categories load. Novig's federal designation covers sports event contracts specifically, so sports is the product, not the starter menu.
That narrowness is why the label matters. Novig is a sports prediction market, or just a sports exchange. Calling it a prediction market with no qualifier sets you up to look for markets that do not exist there. If you want the broader event-contract world Novig deliberately skips, the category primer on how prediction markets work maps it, and our live hub tracks how these markets work in practice.
Sports-only also explains who the app is for, which raises the obvious next question: what exactly are you signing up for right now?
What You Sign Up For Today Is Not The Finished Product
Novig is mid-transition, and this is the part most pages get wrong in one direction or the other. Some still call it a sportsbook. Others already call it a live, federally regulated exchange. Neither is right.
Today, Novig runs as a dual-currency sweepstakes product. You play with an unredeemable coin currency for fun, or with Novig Cash, which can be redeemed for real cash prizes. This is the sweepstakes model, and Novig's own site and help materials still describe it that way. We re-checked the live site on August 5, 2026, and the sweepstakes structure is still what you get at sign-up.
The regulated future is real, though. On June 16, 2026, the CFTC granted Designated Contract Market status to Ludlow Exchange, LLC, the exchange entity behind Novig. That is the same class of federal designation Kalshi operates under. ProphetX won its own designation days earlier, so this is a two-venue shift toward regulated sports exchanges, not a single launch. We compared the two venues in ProphetX vs Novig. (Disclosure: OddsShopper has an affiliate relationship with ProphetX. We have none with Novig, and nothing on this page is sponsored by either.)
But as of August 5, 2026, the regulated exchange has not gone live. The designation is a license to build, and Novig is still building. So what you sign up for today is the sweepstakes product, and what it becomes shortly is the exchange. If a review tells you Novig is already a regulated exchange, it is early. If it tells you Novig is a sportsbook, it is late.
Where You Can Use It
Availability is the question the transition scrambles most, so we keep it short here: Novig offers broad, state-specific availability under federal oversight, and the footprint moves as the transition progresses. Any state list you screenshot today can be wrong next month. The one check that stays current is the app's own eligibility check for your state, and our guide to where you can use it walks through exactly that. You must be 21 or older.
What It Costs To Trade
Novig's pitch is that peer-to-peer trading is commission-free, with no vig baked into the quote. The claim is theirs, not ours, and the mechanism behind it is real: because the price is a probability and your counterparty is another user, there is no house margin built into the number the way a sportsbook builds its cut into -110 pricing. The two sides of a market add to 1, not to 1-plus-juice.
Here is the callback: no vig in the quote does not mean trading is free. Your real cost on any order book is the spread, the gap between what buyers bid and sellers ask. Cross it for an instant fill and you paid it. Post your own order and wait, and you might get the number you wanted, or you might never get filled. We are not telling you Novig's prices are better or worse than anyone else's; price quality is a claim you should demand measurement for, and it is not this page's job. The honest advice is the one that works on every platform: compare any quote against the wider market before you act. Our free live odds screen shows the number across every major book for exactly that reason.
How Deep The Books Actually Are
The checkable strength of Novig is breadth: how many of its listed markets actually carry live orders you could trade against. In our August 4, 2026 catalog read, 236 of 254 MLB stolen-base markets carried resting orders — about 93% of a niche prop board, the kind of market that sits empty on plenty of platforms, quoted almost wall to wall that day. Breadth is a snapshot and moves daily, so treat the number as a dated reading rather than a promise. But it says something concrete about the product: this order book is not a ghost town.
Note what we measured there: how many markets were quoted, not how good the quotes were. Those are different questions, and the second one is where marketing loves to live.
The Risk You Should Understand First
One habit to bring to any binary market, Novig included. When you sell an unlikely outcome, you collect a small premium and risk most of a dollar — sell a contract priced around 6% and you are collecting six cents to put roughly 94% of a dollar at risk. Roughly speaking, one loss erases the premiums from about 15 wins. That asymmetry, not your hit rate, is what decides whether a long-shot-selling style survives, and it is the single most common way order-book newcomers hurt themselves. If the shape of that trade is new to you, read up before you size up.
For transparency: Stokastic, our parent company, actively trades prediction markets and holds positions in them, which is exactly why we write about the mechanics rather than telling you what to trade. Nothing on this page is a pick or a recommendation, and event contracts can lose their full worth.
Novig FAQ
Is Novig a prediction market? It is a sports prediction market. It runs on the same peer-to-peer, probability-priced mechanics as Kalshi or Polymarket, but its catalog is sports only: eight leagues as of our August 4, 2026 read, and zero non-sports markets in its history.
Can you trade elections or weather on Novig? No. No elections, no economics, no weather, no crypto. Its federal designation covers sports event contracts specifically.
Is Novig a regulated exchange? Not yet, as of August 5, 2026. Its exchange entity, Ludlow Exchange, LLC, holds a CFTC Designated Contract Market designation granted June 16, 2026, but the regulated exchange has not gone live. Today's product is a dual-currency sweepstakes model.
Does Novig charge vig? Novig's claim is commission-free trading with no vig in the quote, and mechanically the two sides of a market do sum to 1. Your practical cost is the bid-ask spread and the wait for a fill, which is true of every order book.
What does a Novig price actually mean? The price is the market's implied probability. A contract at 50 cents means the crowd of traders sees a 50% chance; 25 cents means 25%. Winners settle at $1, losers at $0.
Is there a house setting the lines? No. Prices come from user orders meeting in the book. If nobody posts an order, there is no market, which is why breadth matters more here than on a sportsbook.
In Summary
Novig is narrower than the "prediction market" label suggests and simpler than a sportsbook underneath: a sports-only order book where you are matched against people, priced in probabilities, mid-way through becoming a federally regulated exchange. The mechanic is the durable part. The wrapper is what changes — a sweepstakes product at sign-up today, a CFTC-designated exchange once Ludlow Exchange goes live — while the catalog stays exactly what it has always been: eight sports leagues and nothing else. In the meantime, the compare-the-market habit works anywhere, starting with today's free expert picks.
21+. Availability varies by state; check eligibility in the app. Novig's product model and terms are set by Novig and are changing as it transitions to a CFTC-regulated exchange. Event contracts and sweepstakes entries involve risk and can lose their full worth. Nothing here is trading or betting advice. OddsShopper has no commercial relationship with Novig or Kalshi; we do carry offers for some other platforms, including ProphetX, disclosed where named above.
