Prediction markets have leaped from a niche financial concept into an expanding phenomenon that enables users to trade on real-world events. Kalshi is one of the most well-known platforms in this industry, offering a wide range of prediction markets and a seamless user experience. With more and more people looking to get involved in the prediction market space, it is no surprise that many are joining Kalshi.
However, this big name in the prediction market industry faces a lot of competition, and there are plenty of viable alternatives. Finding sites like Kalshi isn’t simply about looking for the same markets and features you can find elsewhere. Lots of traders may be looking for better liquidity markets or faster live trading. It may also simply be the case that Kalshi isn’t available in their region.
Whatever the case, we delve into the best alternative sites to Kalshi.
Kalshi Overview
Before we go into the details of the best sites like Kalshi, I think it is worth briefly explaining how Kalshi works. Kalshi is a prediction market app where traders take positions on whether specific events will happen. These events can range from outcomes on elections to sports, economics, and pop culture. The contracts typically have a yes/no structure, and the market price changes as traders update their expectations. Kalshi operates under the Commodities Futures Trading Commission (CFTC), which ensures the app complies with all regulations to keep users safe.
Although essentially, most prediction markets work in the same way, there are still several differences between Kalshi and other sites. Most of these differences revolve around how the markets are presented.
Best Kalshi Alternative Prediction Market Sites
To keep the list short and concise, we have chosen to pick platforms that have a similar number of markets and strong liquidity during big sporting events. Not all of these competitors are built the same, and choosing the right prediction market site for you depends on how you want to trade.
#1. Polymarket
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, Polymarket is an excellent choice for traders who are looking for a wide variety of national and international markets.
Polymarket Pros:
- More markets than other prediction market apps
- No banking or trading fees
- Sports markets that include totals and point spreads
- Fast-trading environment
Polymarket Cons:
- Only recently launched so may need time to mature
- Cryptocurrency may put people off
#2. ProphetX
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.
ProphetX Pros:
- Can set your own odds with limit orders
- Excellent P2P and prediction market features
- Live trading during games
- Excess of props
ProphetX Cons:
- Limited markets on select sports
- Few payment methods offered
#3. Novig
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.
Novig Pros:
- Daily rewards
- Peer-to-peer functionalities and make orders
- Ability to post your own odds
- Parlays, SGPs, live bets, and futures offered
Novig Cons:
- 3% fees on select deposit methods
- Smaller market selection than competitors
#4. Crypto.com
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.
Crypto.com Pros:
- Low fees
- Withdrawals processed instantly or within 1 hour
- Partnership with Underdog ensures lots of options
- Combines prediction markets with existing crypto exchange
Crypto.com Cons:
- Fewer options than other prediction sites, such as breaking news
- Site is tricky to navigate
#5. OG.com
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.
OG.com Pros:
- Large sports market depth and parlay options
- Only charges $0.02 on any trades
- Sports betting boosts and bonuses
- Fixed fee schedule
OG.com Cons:
- Limited rewards for existing users
- Withdrawals can be lengthy
How To Choose Best Sites Like Kalshi
Deciding which Kalsi alternative is all about how you prefer to trade, how much you are willing to risk, and the type of markets you are interested in. There are some platforms that focus solely on a limited number of markets and prefer simplicity, while others prefer to focus on liquidity, speed, and broader coverage.
With that said, there are some things we think you should certainly consider when deciding on the best Kalshi alternatives.
- Liquidity: You should always check what the liquidity is first before trading on a prediction market app. More active markets typically mean better pricing and easier exits.
- Fees and Costs: Even the smallest differences in fees can soon add up for frequent traders. Make sure you have done your research and have compared fees across numerous platforms.
- Market Variety: Some platforms will focus on just sports, while others include topics such as pop culture and politics. If you are looking for broader coverage, make sure you use the platforms that provide options beyond only sports.
- Check regulation status: You must check the regulation status and trust level of any prediction market platform before using it. You should always use a regulated platform as they will offer more stability and protections.
- User experience: The whole user experience consists of how easy it is to fund your account, to navigate from the homepage, and to place trades. Look for a platform that matches your needs. For example, simpler dashboards are better for new users, while more cluttered, advanced layouts suit experienced traders better.
Prediction Market Trading Speeds
Prediction market trading fees occur when you buy, sell, or settle a contract. They will often vary by platform, market type, and contract price.
| Prediction Market App | Fee Structure |
|---|---|
| Kalshi | Variable per-contract |
| Polymarket | 0.75% at the 50/50 price point |
| ProphetX | 2% trading fee on net profits from winning trades |
| Novig | zero trading or house commission fees |
| Crypto.com | Tiered (Starts 0.4%–0.5%) |
| OG.com | Spread-based (0% explicit commission) |
Fees can have a bigger impact on traders than you might expect. This is especially true over a longer period of time, or when you are placing a high volume of trades. As we have mentioned above, even the smallest differences in price can have a big impact.
Are Sites Like Kalshi Legal In The US?
Yes, prediction markets are legal in the United States, although the regulatory landscape is more complicated than it is for regular sports betting markets. Sites like Kalshi operate under the Commodity Futures Trading Commission (CFTC), which is the regulatory body that oversees the industry. Due to this structure, the model is different from the state-by-state licensing process that sports betting operators follow. This makes prediction site apps a genuine alternative in states where there are limited sports betting options.
That is one of the reasons why sports-related contracts are proving to be massively popular.
