Certain limitations apply. The offer is available to new users only, subject to the terms and conditions at ProphetX. 18+ only. Restrictions and eligibility requirements apply. Event contract trading involves significant risk and is not appropriate for everyone. Please carefully consider if it is appropriate for you in light of your personal financial circumstances. ProphetX products are not available in all jurisdictions. See ProphetX terms for more information.

What ProphetX actually is

ProphetX is a prediction market built around sports. You buy or sell a yes/no contract at a price in cents, and that price is the market's implied probability — 44c means the market thinks 44%. Because there is an order book, you are trading against other participants rather than accepting a fixed price from a house.

The important structural point for 2026: ProphetX now operates as a CFTC-licensed prediction market in 49 states plus D.C. (not Nevada), which is a different framework from the sweepstakes products it ran previously. Terminology matters here — you deposit and trade contracts, and every position settles under published market rules.

What you can trade

• NFL: game outcomes, season-long futures and player markets through the season.
• NBA and college basketball: game and series contracts plus season futures.
• MLB and NHL: daily game contracts across the schedule.
• Soccer, golf, tennis and combat sports: event and tournament contracts.

ProphetX is built around sports; check the app for other markets. That focus is the single biggest reason to hold a second account.

The $50 / $75 offer

Eligible new users can trade $50 and get $75 with code FLPREDICTS. Practically, $50 in qualifying trades unlocks $75 in promotional credit — the largest credit in dollars among the offers we track, though it needs more trading than Kalshi's or Polymarket's. Certain limitations apply and the offer is new-users-only under ProphetX's current terms, so read them at sign-up before you fund.

ProphetX for Florida traders

If your interest is the Dolphins, Buccaneers, Jaguars, Heat, Marlins, Rays or Florida college football, a sports-native book is a better daily driver than a general-purpose exchange. Florida also has no state income tax, though federal reporting rules still apply to gains — keep your own records.

Our recommended stack: Polymarket US for breadth and the deepest books, ProphetX for sports depth, Kalshi for hurricanes and macro on desktop.

Does ProphetX have politics or weather markets?

ProphetX is built around sports; it has also certified election contracts with the CFTC (September 2, 2026). Check the app for other markets. For elections, hurricanes or economics, see Polymarket US or Kalshi alongside it.

How does ProphetX compare to Polymarket and Kalshi?

We rank Polymarket #1 for breadth and liquidity, ProphetX #2 as the best sports specialist, and Kalshi #3 for web access, weather and macro. Many traders keep more than one account.

Can I close a ProphetX position early?

Order-book pricing means a contract you bought at 40c can be sold when the price moves, so you can take profit or cut a loss before the event finishes, subject to available liquidity.
