We compared five Polymarket alternatives on features, fees and supported chains, and noted where each one falls short of Polymarket.
No project pays to be listed. How we rank
Kalshi is the only Polymarket alternative on this list open to US users: like Polymarket US, it is regulated by the CFTC as a designated contract market. Below are five prediction markets compared on US availability, maker and taker fees and how you fund an account. Limitless, Opinion and SX Bet all bar US users in their terms or on their site.
Polymarket is a prediction market for yes/no contracts on real-world events. US residents use Polymarket US, run by QCX LLC as a CFTC-regulated designated contract market that trades in dollars. The international product is crypto-based, separate, and has its own markets. See the full Polymarket profile →
Polymarket US and the international Polymarket are separate apps with separate markets, so a market you see on one may not exist on the other.
Polymarket US trades in US dollars only, not crypto. Kalshi accepts crypto deposits from US users.
On Polymarket US the taker fee is 0.0695 x contracts x p x (1 - p), which peaks at $1.74 per 100 contracts at a 50 cent price.

|---|---|---|
| Polymarket ORIGINAL | Baseline | Yes, via Polymarket US (QCX LLC, CFTC-regulated DCM); international app is separate |

“Not verified” means we have not yet checked the value against the project’s own documentation.
A US exchange for event contracts, regulated by the CFTC as a designated contract market, the same status as Polymarket US. It accepts bank, card, PayPal, Cash App and crypto deposits. Limitation: a custodial account with identity verification.
A prediction market on Base with hourly, daily and weekly markets; winning shares pay $1 in USDC. AMM markets charge a flat 0.40%, and order book makers pay nothing. Limitation: its terms bar users from the United States.
A blockchain prediction market where funds stay in the user's wallet or the smart contract, mainly on BNB Smart Chain with AMM markets on Abstract and Linea. Order book makers pay no fees and get rebates. Limitation: AMM buy fees reach 2% on some markets.
An order book prediction exchange focused on macroeconomic data and news. Takers pay 0% to 1% depending on market probability, makers pay nothing, and Opinion covers gas for matching and settling. Limitation: its terms list the United States as a restricted jurisdiction.
A peer-to-peer sports prediction market where users post or fill odds on an order book in USDC. Takers pay 1% of net profit on winning bets, makers pay 0%, and SX Bet covers gas on bets. Limitation: the site says it is not available in the United States.
In the US: Kalshi, a CFTC-regulated exchange like Polymarket US. Outside the US: Limitless for short-term crypto markets, SX Bet for sports.
For US residents, Kalshi is the one direct alternative here: it holds the same CFTC designated contract market status as Polymarket US and also takes crypto deposits, which Polymarket US does not.
Limitless, Opinion and SX Bet settle in crypto and charge makers nothing, but all three exclude US users. Myriad Markets keeps funds in your own wallet; check its terms for your location before you deposit.
