The prediction markets, ranked. Same rigor, no sponsor favors.

With a polished app, tons of markets, and industry-leading liquidity, Polymarket is clearly one of the industry's best prediction markets.

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.

Novig ditched the sweepstakes model for a CFTC-regulated exchange this summer, and the move paid off. With true no-vig, peer-to-peer pricing and fee-free pregame trading, it's one of the sharpest values in the prediction market space right now.

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. It's polished, easy to fund, and socially engaging — but market-orders-only trading and a still-thin order book outside major sports keep it from the top tier.
