ProphetX review of a price you post or a price you take
ProphetX is a peer sports market: you either take a price another person already posted, or you post a price and wait for someone else to take it. ProphetX's own pages describe that exchange as the alternative to betting against a book. The fee is the number on the confirm screen. State access is whatever the app allows in your location today. Adults 18+ only. This is not legal, financial, or tax advice, and it is not a promo code.

What this ProphetX review tests on a ticket
This ProphetX review tests a method, not a leaderboard. The method is: name the counterparty, write down the filled price, and compute the operator's dollars from the screen in front of you. ProphetX's about page says the company built a peer exchange because a sportsbook is on the other side of the customer. That is the company's account of its own product. It does not tell you today's spread, and it does not tell you whether your state will let the app open.
Adults 18+ only. You can lose the stake. Nothing on this page is legal advice. Regulatory sentences on a company site are theirs to keep current. If you need a ruling about your location, ask a qualified person and read the screen that accepts or blocks you. If spending is no longer affordable, start with responsible gambling.
The wider map of these products sits in Sports betting guides. Read it next to the Novig review, the Sporttrade review, and Novig vs ProphetX. Matching two customers, as a category, is explained in how a betting exchange works. Use that page for the vocabulary. Use the confirm button for the price. This article does not publish promo codes.
Posting an offer is not the same act as taking one
A resting offer is someone else's willingness. When you take it, you trade immediately, up to the size that is actually there. When you post, you are asking the market to come to you. You might want a better number than the one on the screen. You might also want size that is not there yet. Until another person accepts, your cash is an instruction. News can move, the game can start, and the instruction can still be untouched.
Write the average fill, not the number you typed. A post for $200 that fills $40 is a $40 position plus a leftover order. The leftover can be canceled under the app's rules. Record it separately so you do not talk about $200 of risk you do not have.
The price itself is a probability in disguise. A contract that pays $100 and costs $61 needs the side to happen more than 61 percent of the time before any extra charge, or you lose money on average. The conversion between American odds, decimals, and that percent is in the odds converter. ProphetX will show whatever format the current build uses. Convert it yourself so two screens can be compared.
Suppose you take a contract at $61 that pays $100 if the side hits and nothing if it misses. You have risked $61 to receive $100 gross. Profit before any separate fee line is $39. Suppose the confirm screen also lists a $1.50 charge on that win. Net profit in this story is $37.50, and the break-even percent inches up. The $1.50 is an illustration of how to apply a line you saw. It is not a ProphetX fee. The real line is the one on your entry. Read it on the entry, then replace every Suppose number.
Selling out early is a second trade
A game takes hours. A price can move in minutes. If the app lets you sell a contract before settlement, the buyer is another participant paying today's price, not a formula printed in a review. You might lock a gain. You might lock a loss that is smaller than a total miss. You might find no buyer at all, which means you still hold the original contract.
That control is easy to confuse with a sportsbook cash-out quote. The sportsbook version is the book's own number. The peer version exists only when someone will take the other side. Cash out betting explains the general decision. It does not quote ProphetX's current buyback price, because this page does not have your screen.
Partial sales need the same average-price habit as partial fills. Suppose you bought at $61 and you sell half at $70 before the game ends. The sold half has a trading result. The unsold half is still a live contract that can finish at $100 or at nothing. Add those two results after settlement. Do not average them in your head and call it one price.
Liquidity is the quiet cost. A market with a wide gap between the best buy and the best sell makes both entry and exit expensive. The gap is not a fee percent, and this review will not invent one. It is the distance between two real orders. If that distance is most of your expected edge, you do not have an edge. You have a hope.
A second example, this time with a prize table
Some screens never show a pool. They show a contract price and, sometimes, a separate charge. Other screens, including contests that sit near an exchange in the same conversation, show entries and prizes. The subtraction is the same idea. Take equals entries minus prizes. If you only have a percent, multiply it by the base the screen names, stake or profit, and you should land on the same dollars.
Example 2 is a pool, labeled Suppose so it cannot be mistaken for a live board. Fifteen people pay $20. Entries are $300. The table pays $180, $50, and $25. Prizes are $255. Take is $300 minus $255, which is $45. Forty-five dollars divided by $300 is 15 percent of entries in this story only. A real ProphetX ticket will not match these figures. If the product you opened has no prize table, skip the pool and stay with the contract price plus the confirm-screen charge.
| Suppose story | Dollars you write down | What the subtraction says |
|---|---|---|
| Contract taken at $61, pays $100 | A $1.50 illustration charge on a win | Net profit $37.50 in the example, not a published fee |
| 15 people pay $20 | Entries $300, prizes $255 | Take $45, which is entries minus prizes |
Both rows teach the worksheet. Neither row is a user count, a payout clock, or today's commission. ProphetX's marketing has used words like lower fees. Treat that as an adjective. The noun is the number on the confirm screen. This page will not replace that number with a percent it cannot see.
Checklist for the screen in your hand
Run this list on the ticket, not from memory.
- Name the side, the game, and what the contract pays if it hits.
- Record filled size and average price. Park any unfilled remainder on its own line.
- Read the fee on the confirm screen and note whether it hits stake or profit.
- If a prize table exists, compute take as entries minus prizes.
- Let the app accept or refuse your state. Do not trust a state list in an article.
- Check the age the app requires. Eighteen is only the floor for this guide.
- Ignore promo codes. None are printed here, and a code is not a price.
- Risk money you can lose if the contract settles worthless.
The list will not pick a winner. It will stop a posted order from being described as a filled bet. Identity checks and taxes sit outside the worksheet. A winning trade can still be income. Keep the confirm screen. That record is more useful than a review.
Who takes the other side, and what you can recompute
The peer app and the games on this site do not share a counterparty. Read the fee cell for ProphetX as an instruction, not as a statistic.
| Who you play | What the operator keeps | What you can verify | |
|---|---|---|---|
| ProphetX | Another participant who fills your price | Read it on the entry | The confirm screen and the market rules in the app |
| Jackpot and Coinflip | Everyone else in that pot | 5% of the pot at settlement, and the winner receives 95% | A committed seed on the fairness page |
| Roulette | A house-banked 33-slot wheel | About 7.88% theoretical on Purple or Silver after 5% of each winning payout | The pay table: 16 Purple and 16 Silver pay 2x, 1 Green pays 14x |
| P2P Slott | The other player in a 1v1 | 10% of the players' pot when a player wins; a bomb ends the match and the house keeps both stakes | The committed seed and the way the match ended |
The 7.88% figure is the Purple or Silver theoretical edge after the win fee. It describes the wheel's math, not your last hour of play. A longer explanation of how those percents are built sits in how a cut is calculated. If you want the sports category without the wheel, read peer-to-peer sports betting.
Expected value is the habit that ties a $61 contract to a 61 percent break-even, before fees. The worksheet for that habit is in expected value. Apply it to the filled price, then apply the confirm-screen charge on top. Skipping the second step is how a "fair" quote becomes a short one.
Coinflip is a two-person pot, not a sports price
ProphetX, on a sports screen, settles because a game happened. Coinflip settles because two players funded one pot and a committed draw picked a side. The winner receives 95% of that pot because 5% is kept at settlement. There is no spread, no total, and no order book. Your side is half the draw if the stakes match, not a view on a team.
Balances on this site are US dollars. Funding is Bitcoin, or USDC or ETH on Base. After the round, the seed that was committed beforehand can be recomputed on fairness. That page checks the draw. It does not grade a sports statistic, and ProphetX does not publish a Coinflip seed.
Jackpot uses the same 5% pot rule with more than two people, and your chance follows your share of the tickets. Roulette is the wheel in the table above. P2P Slott is the 1v1 with the 10% win cut, and a bomb that keeps both stakes. None of those lines is a promo code or a recent pot size. If you wanted a game price, stay in the exchange and read the ticket. If you wanted two people and a draw, the on-site product is Coinflip.
Open Coinflip for that two-player pot: the live activity block, when present, is fetched from settled rounds, not typed into the article.
