TL;DR:
For US residents, Polymarket, ProphetX and Kalshi are all CFTC-licensed. Polymarket takes the top spot on state coverage and its $25 bonus on a $10 deposit (US app, 49 states + DC, funded in US dollars); ProphetX is the strongest sports-first venue and runs its own federally regulated exchange and clearing house in 49 states + DC (not Nevada); Kalshi wins on simplicity and the most traded volume. Rebet is a social, mobile-first alternative.
