Kalshi is my favorite prediction market app because it offers the widest variety of markets, competitive fees, and key trading tools like limit orders.
Kalshi is great, but there are many reasons why you may be looking for alternatives, such as having other options to compare prices, pay lower fees, or access markets that Kalshi doesn't offer.
My picks for the best Kalshi alternatives are PolymarketUS, OG, ProphetX, Novig, and Crypto.com.
In the rest of this article, I break down these prediction markets, covering how they stack up against Kalshi, fees, market variety, banking options, and more.
Best 5 Kalshi Alternatives & Competitors
I’ve used and reviewed most of the major prediction markets currently available in the U.S. Here are my picks for the best Kalshi alternatives and what each is best for:
- Polymarket US: Best Overall Alternative to Kalshi
- OG: Best Kalshi Alternative for Leverage
- ProphetX: Best Kalshi Alternative for Sports Trading
- Novig: Kalshi Alternative with the Best Promotions
- Crypto.com: Best Kalshi Alternative for Trading on Non-Sports Markets
1) Polymarket: Best Overall alternative to Kalshi
Polymarket is Kalshi’s biggest competitor, and whenever I check U.S. trading reports, it’s usually the one right behind Kalshi in volume.
One thing worth clearing up right away is that Polymarket US is a separate product from the global version. Polymarket Global is crypto-native, while Polymarket US runs on fiat rails, which makes it a more direct Kalshi comp.
Polymarket gives new users $50 in trading funds after a $10+ deposit. Use my promo code ODDSASSIST when signing up to secure the bonus.
The biggest thing Polymarket US has over Kalshi is pricing.
Like Kalshi, Polymarket US uses a model where fees are highest around 50/50 outcomes and lower when a contract gets closer to $0 or $1. The difference is that Polymarket US fees are cheaper. Taker fees range from $0.0005 to $0.0125 per contract, and maker orders incur no fees.
One of the biggest upgrades I’ve seen lately is that Polymarket now supports limit orders. That gives users a lot more control and makes the trading experience much closer to what you get on Kalshi.
I like that Polymarket does not charge banking fees either. It does not offer PayPal or Venmo like Kalshi, but at least it is not taking a small cut every time you move money in or out.
Where Kalshi has Polymarket beat is market variety. Outside sports, Polymarket has 5 markets, while Kalshi has 10+ non-sports categories you can trade on.
I break all of that down in more detail in my Polymarket vs. Kalshi page if you want a full side-by-side comparison.
Where Polymarket Is Better Than Kalshi
- Bigger welcome bonus
- No banking fees
- Lower trading fees overall
- Higher deposit and withdrawal limits
Where Kalshi Is Better Than Polymarket
- Offers PayPal and Venmo
- Props and parlays available for sports trading
- Covers a wider range of sports
- Has significantly more non-sports markets
2) OG: Best Kalshi Alternative for Leverage
OG is Crypto.com's standalone prediction market app. I like using it more than the prediction market section of Crypto.com because it keeps the experience more focused, without extra tools like the crypto exchange or DeFi wallet getting in the way.
The first thing I usually notice when I move off Kalshi and onto another prediction market app is how much the market variety drops off. OG doesn’t fall off nearly as much there, especially in sports.
OG is one of the few trading platforms like Kalshi that offers props, futures, and parlays for sports trading.
On both apps, the fee depends on where the contract is priced. Contracts near 50c carry the highest fee, and the cost decreases as the price moves toward 1c or 99c. Neither platform charges more than $0.0175 per contract.
Kalshi offers more favorable pricing on cheap contracts and near-locks, with a floor of $0.0007 against OG's $0.01 minimum. Kalshi also applies a lower maker fee when you post a limit order, an option OG doesn't provide.
Some traders may like OG more from a banking standpoint. Kalshi and OG both have a wide variety of deposit options, including bank transfer, debit card, Venmo, PayPal, Google Pay, and wire transfer. However, OG has no fees on debit card and Google Pay deposits, while Kalshi charges 2%.
OG offers leverage trading, which you won’t get on Kalshi. That means you can trade with borrowed funds and push for bigger returns. I’d be careful with it, though. Leverage can turn a small mistake into a much bigger loss, and in prediction markets, that’s usually not a risk worth pressing.

Where Kalshi Is Better Than OG

- Payment Methods: ACH, PayPal, Wire, debit card, Venmo, Instant deposit via Plaid
- Payout Speed: Up to 24 hours
3) ProphetX: Best Kalshi Alternative for Sports Trading
ProphetX is a CFTC-approved prediction market platform, so it's federally regulated like Kalshi.
The fee structures differ between Kalshi and ProphetX. Instead of charging a trading fee like Kalshi, ProphetX takes a 2% commission on winning trades, and parlays don't incur any fees. This is nice because you won't pay fees on losing trades, unlike with Kalshi.
I also like that ProphetX provides additional tools to make informed plays. You get a liquidity tracker, an activity chart, and the option to place resting orders, much like Kalshi offers.
I’d call ProphetX the best Kalshi alternative for sports trading because it covers sports really well and mixes in some specialty markets you won’t get on Kalshi. During the Indian Wells Open, for example, ProphetX had a market on either Carlos Alcaraz or Jannik Sinner to win the tournament.
One area where ProphetX falls behind Kalshi is in non-sports markets. You won't find mentions, politics, weather, or any of the many other market categories that Kalshi offers on ProphetX.
Like Kalshi, ProphetX supports cryptocurrency transactions through Zerohash. Kalshi has the edge on payment variety, though, with more funding options, including Venmo and PayPal.
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
Where ProphetX Is Better Than Kalshi
- Offers limit orders
- Props and specials for sports
- Doesn’t charge fees for losing contracts
- Processes payouts within a day usually
Where Kalshi Is Better Than ProphetX
- Offers a much wider range of non-sports markets
- Accepts PayPal & other deposit options ProphetX doesn't
- Features niche sports like chess
- Has deeper liquidity across the board
4) Novig: Kalshi Alternative with the Best Promotions
Novig is a federally regulated prediction market that went from a sweepstakes site to a real-money one after securing CFTC approval via its Ludlow Exchange in June 2026. It's available in every US state except Arizona, Michigan, and Nevada.
Like Kalshi, Novig starts you off with a welcome bonus, giving you $25 in Trade Credits after a $10 deposit when you use promo code ODDSASSIST.
With Kalshi, the welcome bonus is about all you get. Novig keeps the promos coming after that.
Its referral program pays you and your friend $25 each once they sign up and deposit $10, and you can repeat that for up to five friends.
Then there's the monthly Points Program. You collect points every time you trade, and those points bump you up through Novig's ranks. When the month ends, Novig hands out a shared cash reward, and how much you get depends on how high you climbed.
Unlike Kalshi, Novig zeroes in entirely on sports. You'll find baseball, tennis, golf, MMA, and both men's and women's basketball, most of them stocked with props and futures on top of the usual game winners. It isn't as broad as Kalshi's catalog, but it's far from bare-bones.
As for fees, Novig charges a taker fee that tops out around $0.0075 per contract, and makers pay nothing at all. That makes Novig one of the rare prediction markets with cheaper trading fees than Kalshi.
Novig shows the full order book for each position, so you can see exactly where the bids and asks stack up before you trade. You can also make limit orders. That's a level of control few platforms besides Kalshi offer.
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
Where Novig Is Better Than Kalshi
- Offers more promotions
- Charges lower trading fees
- Facilitates free withdrawals
Where Kalshi Is Better Than Novig
- Offers a wide range of non-sports markets
- Has deeper liquidity for niche markets
- Accepts more deposit and withdrawal methods
- Features more sports leagues
5) Crypto.com: Best Kalshi Alternative for Trading on Non-Sports Markets
Crypto.com is one of the few alternatives that can match Kalshi in name recognition.
It’s one of the biggest crypto platforms in the world, and prediction markets are only one part of the product. The same app includes investing, staking, wallets, NFTs, and other crypto tools.
On non-sports markets, I’d call it a close matchup with Kalshi.
Crypto.com covers finance, politics, economics, and culture, much like Kalshi does. Kalshi still has a few more market categories you won’t see on Crypto.com, like Mentions, but Crypto.com holds up better here than most rivals.
Crypto.com is one of the few places where you can trade sports outside the usual major leagues, like golf and tennis. Where it’s behind the eight ball is player markets, because you won’t find much in the way of player props.
I do like that Crypto.com supports limit orders. Not every Kalshi alternative does, and this is a huge factor I consider when evaluating prediction markets. You can choose your price, place the order, and wait to see if the market gets there.
The one place Crypto.com falls short on fees is taker pricing. Both platforms scale the fee to the contract price and cap it at $0.0175 per contract.
Kalshi charges considerably less at the extremes, going as low as $0.0007 per contract, while Crypto.com's minimum taker fee is $0.01.
Banking is a bit of a split decision. Like Kalshi, Crypto.com accepts PayPal and crypto. The difference is that Kalshi doesn’t charge for PayPal deposits, while Crypto.com does.
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
Where Crypto.com Is Better Than Kalshi
- Friendlier fees on 50/50 markets
- Non-prediction market trading options
- Faster withdrawals (up to 24 hours)
- Better reward program
Where Kalshi Is Better Than Crypto.com
- Covers more sports
- Charges more favorable taker fees overall
- Offers sports markets for player performance
- Has Mentions markets

How We Rate Kalshi Alternatives & Competitors
I graded each Kalshi alternative against key categories like market depth, pricing, banking, promos, and trading tools. Here’s how those factors played into the final scores.
Liquidity
Liquidity plays a big role in how prediction markets work. If there is not enough money on the other side of the market, your trade may not get matched at all. Even when it does, you may have to accept a worse price than the one you wanted.
That happens because every trade needs a counterparty. Someone has to be willing to take the other side of your position. If that interest is not there, the market gets thin, spreads get wider, and execution gets tougher.
This is also why pricing alone never tells the whole story. An app can look cheap on paper, but if liquidity is weak, that pricing edge may not help much. You still need enough depth in the market to get in and out at a number you can live with.
Kalshi usually does a good job here, but it is not perfect across every market. In some niche events or lower-interest markets, even Kalshi may not have enough liquidity to fill the trade you want at the price you want. That becomes a bigger issue if you are trying to trade a larger size.
In most cases, the strongest liquidity comes from platforms with a big user base and some staying power. Brands that have been around longer and built up more name recognition, like Crypto.com, usually have an easier time keeping markets active.
Newer platforms and smaller brands can have a harder time there. Apps like Novig or Underdog Predict may offer strong pricing or useful promos, but some markets can still be thinner, especially outside the most popular events.
Fees
Most major prediction market apps now use a probability-weighted fee model, where the cost scales with the contract price rather than staying fixed. Kalshi, Crypto.com, OG, Robinhood, and Polymarket all price fees this way, charging the most on contracts near 50c and less toward the extremes.
Some platforms also give traders a break when they add liquidity. If you post an order instead of taking what is already available, the fee may be reduced or removed entirely. That can make a real difference if you trade more patiently and let the market come to you.
ProphetX is its own category here. Instead of charging a standard trading fee, it takes a commission only on winning trades. That is a very different model from what you get on Kalshi and most other prediction market apps.
Market Variety
This part of the Kalshi alternative search comes down to two things: how much coverage a platform gives you across sports and non-sports markets, and how many different ways it lets you trade within each category.
On the non-sports side, Robinhood and Crypto.com stand out as the best substitutes. Both go deeper than most of the field with markets tied to technology, economics, crypto, and similar event categories.
For sports traders, the strengths are more split up across the best prediction market apps for sports. OG and Novig do the best job with props, while ProphetX stands out most for futures.
Underdog Predict is the outlier here. What makes it different is the ability to mix DFS picks with prediction markets, giving it a twist that the other Kalshi alternatives don’t have.
User Experience
Prediction market trading comes with a steeper learning curve than a standard sportsbook or DFS app, especially for beginners. That makes the user experience a bigger deal than it may seem at first. When a platform is easier to navigate, price, and understand, it is much simpler to trade with some confidence.
Robinhood, Polymarket, and FanDuel Predicts stand out as some of the most user-friendly options in this group. They are easy to navigate and understand, especially for beginners.
Just as important as the visual side is the feature set. The biggest tool, in my view, is the ability to place limit orders. There aren't many sites like Kalshi that offer that option, which is a big reason it still stands out. Among the alternatives, Crypto.com is one of the few that also supports limit orders.
Banking
While Kalshi offers virtually every major deposit option, it's something that varies much more among competitors. Some are very limited, while others, like OG, have similar methods available.
Another part of the banking picture is payout speed. If getting your money out quickly is a priority, Crypto.com has a strong case as the best Kalshi alternative for fast withdrawals. Its cash-out window runs from 0 to 24 hours, which is better than what you usually get from most prediction market apps.
Fees also deserve a close look here. Most prediction market apps will charge you for deposits, withdrawals, or both. Then you have platforms like Polymarket and Novig, which do not charge any commission on either side. That can make a bigger difference than people think once you are moving money in and out regularly.
