ProphetX is a prediction market, designated by the CFTC as a contract market in June 2026. Instead of betting against a sportsbook, you buy a contract on an outcome at a price in cents that pays $1 if the outcome happens. On NinjaBet.com ProphetX is the second leg of a hedge: the Bet Finder pairs a sportsbook promo with the opposite outcome on ProphetX when that is the cheapest hedge, and it is available in every state NinjaBet.com serves except Nevada. A free account can already pair it with DraftKings.

How do you use ProphetX for matched betting?

Open and fund a ProphetX account.
Find the promo you are completing in the Bet Finder: when ProphetX offers the best price on the other outcome, the row shows it as the second leg.
Buy the contracts on that outcome for the amount shown. The odds converter turns a price in cents into American odds (40 cents is +150).
Log both legs in the Bet Tracker. Our ProphetX guide and prediction markets article go into detail.

You must be 21 or older (18 in a few states) and located in a state where ProphetX is licensed to bet. Gambling can be addictive: call or text 1-800-GAMBLER for free, confidential help. Earnings from promos are an estimate rather than a promise.

ProphetX: frequently asked questions

Is ProphetX a sportsbook?

No. It is a prediction market: you buy contracts on an outcome from other users at a price in cents, and each contract pays $1 if the outcome happens.

Where is ProphetX available?

In every state NinjaBet.com serves except Nevada. The list at the top of this page comes straight from the tools.

Does ProphetX charge fees?

Check the fees in your ProphetX account before you trade: enter any commission in the calculator so the hedge stake accounts for it.

How do I convert a ProphetX price into odds?

Divide 100 by the price in cents to get decimal odds: 40 cents is 2.50, or +150 in American odds. The odds converter does it for you.

Why use ProphetX in matched betting?

Because it often prices the other outcome of a game close to fair, which makes the hedge of a sportsbook promo cheaper. The Bet Finder chooses it only when it is the best option.
