The global version of Polymarket is one of the best prediction markets available. The U.S. version hasn’t reached that level yet.
Right now, the U.S. version of Polymarket doesn't stack up against competitors because it offers only a few non-sports markets.
If you're looking for a Polymarket alternative that offers more, I recommend checking out Kalshi, OG, ProphetX, Novig, and Crypto.com.
In the rest of this article, I walk through what each platform does well and why each one has a real case as a Polymarket replacement.
5 Best Polymarket Alternatives
After testing extensively across the U.S. prediction market scene, I narrowed it down to five platforms that I consider excellent alternatives to Polymarket.
- Kalshi: Best Overall Polymarket Alternative
- OG: Best for Margin Trading
- ProphetX: Best for Sports Props
- Novig: Best Pricing
- Crypto.com: Best for Non-Sports Markets
1) Kalshi: Best Overall Polymarket Alternative
Kalshi is a CFTC-regulated prediction market platform, which makes it legal across the U.S.
It’s my highest-rated prediction market app, and it outshines Polymarket in most areas, starting with market variety.
Currently, Polymarket offers 5+ non-sports markets and sports markets with the main lines (spread, total, and moneyline) for each game. Kalshi offers many more market types in sports, such as props, as well as a wide array of non-sports categories like Mentions, Politics, Culture, Weather, Crypto, and more.
For new users, Kalshi offers a trade $25, get $500 welcome bonus. It’s significantly larger than Polymarket’s deposit $10, get $20 trading bonus.
Fees are another area where Kalshi shines. Taker fees (for buying something currently available) range from $0.0007 to $0.0175 per contract. Maker fees (which you pay when you place a limit order that isn't immediately filled) range from $0.000175 to $0.004375 per contract. That puts Kalshi in a very strong spot on pricing compared to the other Polymarket alternatives.
Kalshi offers perpetuals, or perps, a product type you won’t find on Polymarket’s U.S. app. With perps, traders can back crypto prices to move up or down, instead of only taking a Yes/No position on an event.
Kalshi also has many more banking options than Polymarket. Kalshi offers PayPal, Venmo, Cash App, and crypto, in addition to the Apple Pay, bank transfer, debit card, and wire transfer options that Polymarket offers.
Kalshi also offers a lot more trading tools than Polymarket. You get social features like news and leaderboards, all of which are missing on Polymarket's U.S. app.
Overall, if you're looking for the best Polymarket alternative, it's hard to argue that any platform other than Kalshi should be the #1 choice.
Kalshi Quick Facts:
- OA Rating: 92/100
- Sign-Up Bonus: Trade $25, Get up to $500 with promo code ODDSASSIST
- Fees: $0.07-$1.75 Per 100 contracts taker/$0.02-$0.44 per 100 contracts maker
- Sports Markets: NFL, NBA, MLB, NHL, soccer, esports + 13 more
- Other Markets: Politics, art, culture, crypto, climate, economics, mentions, companies, financials, tech & science, health, world
- Payment Methods: Online banking, PayPal, Venmo, wire, debit card, cryptocurrencies
- Payout Speed: Up to 5 business days
2) OG: Best Polymarket Alternative for Margin Trading
OG is Crypto.com’s standalone prediction market app, and unlike the parent platform, it focuses on this one type of trading rather than bundling other types into the app.
I prefer OG’s user experience over Polymarket. While Polymarket is easy to use, mostly because of its very limited market selection, OG has a smarter navigation system, more information about markets, and an overall nicer trading setup.
Like Kalshi, OG offers a much better market variety than Polymarket. You get sports trading options that aren’t available on Polymarket, such as futures and props. That’s a big deal to me, because there still aren’t many Polymarket alternatives where I can trade markets like passing yards, receiving yards, or anytime touchdown scorer props.
Outside of sports, OG also offers markets for financials, culture, crypto, companies, economics, climate, and more, some of which are missing on Polymarket.
OG also has AI Alpha, an assistant built right into the app. Ask it about any matchup and it hands you recent form, head-to-head numbers, and a breakdown of what the current prices are telling you. Polymarket has nothing like it, so you're doing that homework in another tab.
In terms of banking, OG outshines Polymarket with Venmo and PayPal, in addition to bank transfer, debit card, Apple Pay, and wire transfer.
Fees are the one area where Polymarket has a clear edge. Both platforms scale the cost to the contract price, but Polymarket's taker fee starts at $0.0005 and makers pay nothing. OG's taker fee starts at $0.01, and there's no maker rate to work with.
OG Quick Facts:
- OA Rating: 90/100
- Sign-Up Bonus: Trade $10, Get $10
- Fees: Up to $0.0175 per contract
- Sports Markets: NFL, NBA, MLB, NHL, soccer, tennis + 4 more
- Other Markets: Companies, financials, culture, politics, economics
- Payment Methods: ACH, PayPal, Wire, debit card, Venmo, Instant deposit via Plaid
- Payout Speed: Up to 24 hours
3) ProphetX: Best for Sports Props Among Polymarket Alternatives
ProphetX is a CFTC-approved prediction market platform, just like Polymarket.
If you’re looking for a Polymarket alternative that offers great promos, ProphetX deserves a look. It offers a referral program with up to $50 in bonus for each friend you bring in, along with a trade $10, get $20 welcome bonus.
Like every other Polymarket competitor on this list, ProphetX also offers a much better market selection. Polymarket mostly sticks to the major sports leagues and UFC, while ProphetX branches out into more niche sports like NASCAR, UFL, golf, and a wide variety of soccer leagues.
ProphetX also gives you many more ways to trade every game. On the NFL, for example, you can find more than 170 markets, including tackles, touchdown scorers, and first-half totals.
ProphetX has pulled back on non-sports coverage since receiving CFTC approval and moving to a real-money model. Right now, the platform is sports-only. Polymarket is going the other way, expanding into categories like temperature, politics, tech, the economy, and culture.
The fee structure is very different between the two. Polymarket charges small fees when buying and selling contracts, while ProphetX takes a 2% commission on winning straight trades and doesn't charge any fees on parlays.
Payment options are one area where I’d give Polymarket the edge, since ProphetX doesn't support credit or debit card payments, which are arguably the most popular banking option among traders.
ProphetX Quick Facts:
- OA Rating: 89/100
- Sign-Up Bonus: Trade $10, Get $20
- Fees: 2% Commission on winning single trades; parlays don't incur any fees
- Sports Markets: NFL, NBA, MLB, NHL, F1, golf, UFC + 6 more
- Other Markets: Entertainment
- Payment Methods: Online banking, wire transfers, cryptocurrency via Zerohash, and paper checks
- Payout Speed: 48-72 hours
4) Novig: Polymarket Alternative with the Best Pricing
Novig is a federally regulated prediction market that's available in every US state except Arizona, Michigan, and Nevada.
Novig is the only prediction market with trading fees cheaper than Polymarket's. Takers pay at most about $0.0075 per contract, while makers actually win a credit worth up to half the taker fee.
Both platforms offer a welcome bonus, but Novig also has ongoing promos for active traders.
The Novig welcome offer is $25 in Trade Credits after a $10 deposit with code ODDSASSIST. Then there's a referral deal that pays you and a friend $25 each once they sign up and deposit $10, good for up to five friends and $125 total. Active traders also get a monthly Points Program that pays out based on how much they trade.
Novig's sports coverage is still on the narrow side, which is one spot where it feels a lot like Polymarket. That said, Novig has more trading options per sport. Where Polymarket sticks to basic game-winner, spread, and total markets, Novig gives you futures and props like three-pointers made in pro basketball and longest rush in football.
On features, Novig goes toe to toe with Polymarket, offering both a full order book and limit orders. I'd give Polymarket a slight edge here, though, since it also provides an API for traders, which opens the door to automated strategies.
Novig Quick Facts:
- OA Rating: 86/100
- Sign-Up Bonus: Deposit $10, Get $25
- Fees: None
- Sports Markets: NFL, NBA, MLB, NHL, UFC + 3 more
- Other Markets: None
- Payment Methods: Online banking, Apple Pay, crypto, and debit cards
- Payout Speed: Up to 3 days
5) Crypto.com: Best Polymarket Alternative for Non-Sports Markets
Crypto.com is easily the most recognizable among the Polymarket alternatives. The brand is all over the place, from the Lakers’ arena to deals with F1, UFC, and a bunch of other sports properties.
It’s also operating on a much bigger scale than Polymarket. Polymarket is built around prediction markets and pretty much stops there. Crypto.com gives users access to a much wider financial ecosystem, including crypto trading, staking, DeFi, and NFTs.
Unlike Polymarket, Crypto.com doesn’t give new users a small deposit bonus. The promo here is different. If you trade $100 or more, you can win up to 1 Bitcoin worth of CRO, which is the platform’s native token.
For me, the clearest Crypto.com advantage over Polymarket is the range of markets, especially outside of sports.
Polymarket is somewhat limited there, offering 5 non-sports markets. Crypto.com offers more options, with markets tied to finance, politics, weather, the environment, and crypto.
On fees, Polymarket keeps the edge, though the difference has narrowed. Both platforms scale the cost to the contract price and charge makers nothing, but Crypto.com's taker fee starts at $0.01 while Polymarket's goes down to $0.0005.
I’d still give Polymarket the better grade for banking. It doesn’t charge deposit fees, while Crypto.com charges for certain deposit methods. Crypto.com does offer PayPal, though, and that’s one option Polymarket doesn’t have.
Crypto.com Quick Facts:
- OA Rating: 90.5/100
- Sign-Up Bonus: Trade $100, Get Up to 1 BTC in CRO Rewards
- Fees:
- Taker: from $0.01 to $0.0175 per contract
- Maker: No fees
- Sports Markets: NFL, NBA, MLB, NHL, soccer + 5 more
- Other Markets: Companies, financials, culture, politics, economics
- Payment Methods: ACH, PayPal, Wire, debit card, 350+ cryptocurrencies
- Payout Speed: Up to 24 hours

How We Rate Polymarket Alternatives
I reviewed each Polymarket alternative by looking at fees, liquidity, market variety, user experience, and banking. Below, I break down each category and show which apps came out on top.
Liquidity
Liquidity is one of the first things I check when I compare Polymarket alternatives. A platform can have lower fees, bigger promos, or a wider market list, but none of that goes very far when there is little liquidity.
This is where a lot of alternatives start to look different. When a market does not have enough buyers and sellers, you may need to take a worse price, spend more time waiting for the trade to go through, or pass on the trade altogether.
Casual users making smaller trades on major events may not run into this very often. Active traders usually notice it a lot more. The same goes for anyone trying to trade larger amounts. Once position sizes go up, market activity becomes a much bigger part of the experience.
Liquidity changes how I look at fees, too. Some prediction markets look cheaper at first glance, but the savings do not mean much if the market is harder to trade. A lower fee loses some appeal when pricing is worse, or trading activity is not strong enough to support the trade you want.
Among the apps in this group, Kalshi and Crypto.com usually have the strongest liquidity. Both have more name recognition, more user activity, and a better shot at keeping popular markets active throughout the day.
That does not mean every contract is going to have strong activity on both apps. Smaller markets and lower-interest events can still be quieter.
Even so, if liquidity is near the top of your list, Kalshi and Crypto.com are usually the best places to start among the main Polymarket alternatives.
Fees
One thing I always check is how easy the pricing is to understand before placing a trade. The best prediction market apps offer probability-weighted fee models. Crypto.com, OG, Kalshi, and Polymarket charge this type of fee.
Some platforms are better suited to traders who set their own prices and wait for the market to come to them. That can be useful for anyone trying to trade with a little more patience and a little more control over cost.
ProphetX takes a unique route compared to competitors. It does not use the same standard trading-fee model as most other apps here. Instead, it charges a commission on winning picks, which changes how traders need to think about cost.
That’s why I do not treat fees like a simple surface-level comparison. What I care more about is how pricing affects how you trade over time. If you trade often, lower costs can make a much bigger difference. If you trade less, the gap may not stand out as much.
Market Variety
One of the main reasons people look for Polymarket alternatives is to have more trading options. Sometimes that means more event categories. Sometimes it means more options inside the sports and topics they already follow.
The bigger question is not just how many markets a platform offers. It is whether the app gives you more props, more futures, and more ways to trade the events you already care about.
Kalshi and Crypto.com stand out most outside sports. They both give you access to financial, weather, crypto, and other event markets. PredictIt is arguably the best app for politics betting.
For sports-focused users, OG and Novig might be a better fit. Both offer props and futures, which helps a lot if Polymarket feels too limited with its standard spread, total, and moneyline markets.
ProphetX deserves a mention too, especially for traders who like longer-term positions. It offers a wide range of futures, so it makes more sense for that style than for someone who only wants short-term player markets.
User Experience
User experience affects how easy a platform is to use once you open it. Some Polymarket alternatives are easy to learn right away. Others take more time because the layout, pricing, and trade process are harder to follow.
A lot of that comes from how the app presents markets and prices. When everything is easy to find and easy to read, trading feels a lot less clunky. You are not wasting time trying to figure out where to click or what price you are looking at.
Polymarket usually does well here. The interface is simple, the design looks lighter, and the app is easy to move through. For most users, there is not much of a learning curve.
Crypto.com takes a different approach. It gives users more tools but also puts more information on the screen. That can take longer to get used to, especially for newer traders.
One of the bigger differences in this group is limit order support. A limit order lets you choose your own price instead of taking the price already available in the market. That gives traders more control over how they enter a position.
Not every Polymarket alternative gives you that option. For example, FanDuel Predicts and Fanatics Markets don't offer limit orders. Kalshi and Crypto.com are among the few that do, which makes them more appealing to traders who care about price control.
