Best Sites Like Kalshi

Polymarket sits atop this list, and that is because it is widely seen as the cloest alternative to Kalshi for most traders. This is down to the fact that Polymarket offers a wide variety of markets, covering topics like crypto, sports, finance, and tech. During big sporting events such as the Super Bowl or March Madness, the platform provides a large number of active sports contracts with constantly moving probabilities. The recent 2026 FIFA Soccer World Cup Polymarket World Cup winners market saw users trade over $4billion in event contracts.

One of the differences between Kalshi and Polymarket is that Polymarket uses smart contracts and external crypto wallets rather than having everything already there on its own systems, like Kalshi does. This is fine for people who have experience using crypto, but may be slightly off-putting for those who have never used it before.

Another difference between the two is their regulatory status. Both apps are licensed by the CFTC in the US market; however, Polymarket offers a more decentralized experience for users outside of the US. This is because it was created using blockchain technology, which means you can trade through an on-chain system with no KYC requirements unless stated under local law guidelines.

Ultimately, as our Polymarket review found, this is an excellent choice for traders who are looking for a wide variety of national and international markets.

ProphetX used to operate as a social sportsbook until mid 2026, when the operators were approved to launch a prediction market. This platform combines exchange-style trading with a sports-heavy focus. Users can purchase peer sports contracts, create trading parlays, and also set their own market prices. It has kept a lot of the P2P betting features of its previous incarnation, allowing you to view market liquidity and to build orders based on your prices.

You can predict the outcomes of sports games, spreads, totals, props, and lots more. The market liquidity is typically high, and there are lots of opportunities to execute your trades. Unfortunately, there is a 2% charge on all straight trades, but parlays have a 0% commission. I would say ProphetX is ideal for traders seeking value and are obviously interested in making sports trades.

Like ProphetX, Novig was a social sportsbook that had virtual currencies, and in summer 2026 it became a registered Designated Contract Market under the CFTC. Novig is now a fully-fledged prediction market-style platform, and can be viewed as a combination of standard prediction markets and peer to peer betting sites. You can view market prices, pick trades, and place trades. Novig also decided to retain its P2P functions, such as checking alternate lines and setting your own price.

Novig has not stretched itself and focused on multiple topics, choosing instead to concentrate on sports. It has markets on leagues, player props, and live action daily. The platform also has an early payout feature where you can lock in partial returns from hedged wagers. There is also a loyalty program available and site credits (Novig Cash) that you can use to fund your next orders.

Crypto.com is appealing for users who enjoy crypto trading and exchanges. It works in a similar way to Kalshi, with yes/no contracts based on real-world outcomes around sport, politics, and culture. There are also a good number of sports available, and the user-experience enables you to navigate around the platform seamlessly. Anybody who already holds a Crypto.com account will find this is an excellent way to enter the prediction market space with a site you are already familiar with.

Of course, this site has a huge amount of cryptocurrencies which users can use to fund their accounts. Some of these include Ethereum, Litecoin, and Bitcoin. If you already trade cryptocurrencies, this should all look familiar, and that is one of the main reasons Crypto.com is very appealing for existing crypto traders.

OG.com launched in 2026, and it feels different from the rest in the sense of it being more community-driven. It is clearly trying to carve out a niche for itself as it is a new platform and still growing. It offers fixed-fee trading schedules, parlay building trade slips, and numerous bonuses and rewards to attract new users. OG focuses on sports, with heavy coverage of the most popular US sports and a huge depth of markets for individual games. This gives sports traders plenty of opportunities to pick out selections and add them to their trade slips, creating parlay-style contracts.

OG also covers real-world events, but there aren’t as many options as the ‘big two’, Polymarket or Kalshi. There is no doubt OG has chosen to focus more on sports, and the prediction market Boosts and Rewards are a real incentive to attract people to give OG a shot.
