College market depth
ProphetX lists college football and college basketball game contracts and player markets — sports only. Rebet lists college football and basketball game lines and props. If you are here for college football or March Madness, depth matters more than a few basis points of fee difference — a market that does not exist cannot be traded at any price.

ProphetX runs on ios, android (mobile-first) and is 49 states + d.c. — nevada excluded. Rebet runs on ios, android (mobile only) and is 47 states + d.c. — michigan, nevada and washington excluded.
The verdict
Pick ProphetX if: sports-only traders who want peer-to-peer pricing with no built-in house margin. Pick Rebet if: students who want a social, game-shaped experience on a phone.
