ProphetX is the sports-purist's prediction market — a CFTC-regulated exchange built entirely around sports, with true back-and-lay pricing, no-fee parlays, and a commission model that only charges you when you actually win. The tradeoff is liquidity that's still filling in outside the majors.

OG is Crypto.com's entry into prediction markets, running on the same CFTC-regulated Nadex infrastructure that's been federally registered since 2004.

Kalshi is the biggest and most established name in US prediction markets — a CFTC-regulated exchange with the deepest liquidity, the broadest payment options, and a fee structure that beats sportsbook vig by a mile. If you only try one prediction market, this is the one.
