What is ProphetX?
ProphetX is a sports-native prediction market. Instead of taking a price from a house, you trade Yes/No event contracts with other users on game and player outcomes. ProphetX announced CFTC approval to operate as a federally regulated exchange and clearing organization in 2026 and says it now runs nationwide — we present that availability as the company's own statement and recommend confirming eligibility at signup.
Sports-only scope
This is the key difference from Polymarket and Kalshi: ProphetX trades sports and nothing else. NFL, NBA, WNBA, college football and basketball, soccer including the 2026 World Cup, tennis, golf, UFC and boxing. There are no politics, economics, weather or culture markets, which keeps the app focused but means it is not a one-app solution.
Peer-to-peer pricing
Because you are matched against other traders rather than a bookmaker, ProphetX does not bake a house margin into every contract. On liquid NFL and NBA markets that translates into tighter pricing than you would expect from a traditional product; on long-tail props you may need to leave a resting order and wait for a match.
Welcome offer — trade $10, get $20
Sign up through our link, enter MIAPREDICTS at registration, deposit and trade $10 in qualifying sports contracts, and ProphetX credits a $20 welcome bonus. It is the lowest qualifying threshold of any offer we track, which makes it the easiest first bonus for a new trader to actually clear.
App and everyday experience
ProphetX ships iOS and Android apps plus web access. The lobby leads with the day's games, liquidity is shown on each market, and positions can be closed before settlement. Deposit limits and responsible-trading controls are available in the account settings.
Florida availability
Florida is on the eligible list for ProphetX and the MIAPREDICTS offer. For Miami traders that means Dolphins, Heat, Panthers, Marlins, Inter Miami and Florida college markets are all in scope, alongside the 2026 World Cup fixtures hosted at Hard Rock Stadium.
Verdict
Our #2 pick overall and #1 for anyone who only cares about sports. Use ProphetX (code MIAPREDICTS, trade $10 get $20) for game-day contracts and pair it with Polymarket, our #1, when you want politics, economics and culture markets on the same bankroll.
