ProphetX vs Novig: Fees, Markets, and Where Each One Works

Quick Answer

These two are the closest structural match in US sports trading. Both hold a CFTC designation, both match you against other traders instead of a house, and neither prices a vig into the line. ProphetX was designated on 11 June 2026, Novig on 16 June 2026.

Commission is the difference. ProphetX charges 2% on net gains per market on straight trades. Novig charges nothing on a single-outcome trade placed before a game starts, and does charge on parlays and on anything placed while a game is running.

ProphetX covers more ground. Alongside the major US leagues and five European soccer competitions, it currently runs politics markets on Senate races and the balance of Congress. Novig is sports and nothing else.

Ages differ too. ProphetX sets 18, or the local age of majority where that is higher. Novig requires 21 everywhere.

ProphetX vs Novig at a Glance

Which One Costs Less?

The two charge on opposite principles, so a single headline rate won't tell you much.

ProphetX charges on what you win. Its published schedule reads: all straight trades are charged a 2% trading fee on net gains per market. Lose and there's nothing to charge. Win and 2% of the net comes off at settlement.

Novig charges on when you trade. A single-outcome trade placed before the game starts carries no fee at all, for either side. Parlays and in-play trades do carry one.

Run the same $100 profit through both:

That makes ProphetX cheaper than a sportsbook and more expensive than Novig on the same bet. For scale, a sportsbook holds about 4.55% on a standard -110 two-way price, and it holds it whether you win or lose.

Two things that complicate the comparison. ProphetX runs a make-volume rebate program with marginal tiers up to 80%, so a high-volume liquidity provider can bring an effective rate closer to 1%. That's a rebate earned on monthly make volume rather than the rate a normal account pays, so read 2% as your number unless you're posting serious size. And Novig's zero has an edge case: when a market is quiet Novig takes the other side itself, so you pay no fee but the price can be worse.

Parlays work differently again. ProphetX charges the taker at execution, win or lose, on a formula rather than a flat rate, and the maker pays nothing.

What Can You Bet On?

ProphetX is the broader book of the two, which is worth saying plainly because the sports-only framing that follows it around is out of date.

Moneylines, spreads and totals run across MLB, NHL, NBA, NFL, college football, college basketball, UFC and tennis. Soccer covers the Premier League, Ligue 1, La Liga, Bundesliga, Serie A, MLS, the Champions League and the Europa League. Player props and futures extend to the PGA Tour, the DP World Tour and NASCAR. Parlays are supported, with their own rulebook. Live trading runs on all of it.

It also lists politics. Senate winners in several states, a Los Angeles mayoral market and the balance of power in Congress were all live at the time of writing, filed with the CFTC as product certifications.

Novig covers NFL, MLB, NBA, NHL, college, soccer, tennis, golf and MMA, with moneylines, spreads, totals, player markets, season-long bets, live trading and parlays. Parlays are a larger part of its business than most people expect, running at just over a third of all trading.

One interface note for anyone moving between them: Novig dropped American odds on 27 August 2026 on its regulator's instruction and now shows prices as percentages.

Where Can You Legally Use Each One?

This is the least settled part of the comparison and the most likely to have changed since publication.

Novig publishes a footprint. It opened in 47 states plus DC, leaving out Nevada, Arizona and Michigan.

ProphetX publishes none. There is no state list and no state count anywhere on its site, its help centre or its legal documents. Its help centre says only that access is restricted from certain locations and IP addresses as part of its compliance requirements, without naming them. Figures circulating on affiliate sites are not sourced to ProphetX, so check inside the app rather than trusting a number you read elsewhere.

Both operate under federal commodities regulation rather than state sportsbook licences, and that federal question is itself contested. Two appeals courts have split on whether states can restrict these contracts, and New Jersey asked the Supreme Court to settle it on 2 September 2026.

How Old Do You Have to Be?

ProphetX sets 18, or the age of majority where you are if that's higher. Both its Terms of Use and its Market Participant Agreement say so.

Novig requires 21 everywhere.

There's no federal minimum age for these contracts, and state gambling ages don't apply, because they're regulated as financial products. So an 18-year-old can trade on ProphetX in a state where they couldn't legally place the same bet at a sportsbook, and couldn't open a Novig account either.

Which Should You Choose?

• Choose Novig if you trade sports before games start and want the lowest cost on a straight position, or you want a platform that requires 21.

• Choose ProphetX if you want politics markets alongside sports, you post size and can earn into its rebate tiers, or you're under 21 and eligible where you are.

• Use both if you trade often. The same game prices differently on each, and neither charges you to look.

Takeaways

• Cost: Novig on a straight pre-game trade, where it charges nothing against ProphetX's 2% of net gains. ProphetX only charges when you win.

• Range: ProphetX. Broad sports coverage plus politics markets; Novig is sports only.

• Parlays: both offer them, priced differently. ProphetX charges the taker at execution; Novig charges a parlay fee.

• Age: ProphetX is 18 or local majority, Novig is 21.

• Transparency: Novig publishes where it operates. ProphetX does not.

• Structure: near-identical. Both CFTC-designated, both peer-to-peer, both without a house vig. Commission is the real wedge.

Responsible Gameplay

These contracts carry financial risk, and a losing one expires worthless. ProphetX requires 18 or the local age of majority; Novig requires 21.

ProphetX vs Novig FAQ

2% of net gains per market on straight trades, taken at settlement. Lose and there's no fee. Parlays are priced separately, charged to the taker at execution on a formula rather than a flat rate.

Is ProphetX commission-free on props?
No. Props are straight trades and carry the ordinary 2%. Nothing on ProphetX's site exempts them.

Which is cheaper, ProphetX or Novig?
Novig, on a single-outcome trade placed before a game starts, because it charges nothing there and ProphetX charges 2% of what you win. Both are well below a sportsbook, which holds about 4.55% on a standard -110 price whatever the result.

Is ProphetX available in my state?
ProphetX doesn't publish a state list. Its help centre confirms access is restricted from certain locations without naming them, so check in the app. Novig lists 47 states plus DC, excluding Nevada, Arizona and Michigan.

Can you place parlays on both?
Yes. Both support them, and both charge for them, on different models.
