Best Apps Like Kalshi in 2026: Tested Alternatives & Comparison

Find your best Kalshi alternative in seconds

Here's a table with the best apps like Kalshi based on specific criteria.

Compare apps like Kalshi June 2026

With the most available markets of any prediction market site, Kalshi is our top pick. But that doesn't mean there aren't other excellent options available around the country. Here's a table highlighting four of my favorite prediction market apps like Kalshi.

Top 5 apps like Kalshi reviewed

1. Polymarket - Best overall alternative

The debate of Polymarket vs. Kalshi has been ongoing ever since Polymarket became legal in the US again. This CFTC-approved prediction market app is fee-free for maker orders and doesn't charge withdrawal fees, unlike Kalshi.

The only downside of Polymarket is that it doesn't offer as many market types as Kalshi. For example, Kalshi offers nearly 20 sports markets and more than 10 non-sports categories. Meanwhile, Polymarket sticks to major sports, politics, and economics.

That said, Polymarket is excellent for cost-efficient trading, and if you use our Polymarket promo code SBR, you can deposit $20 and earn a $50 bonus. That's two and a half times the $20 Kalshi welcome bonus. Granted, you can receive the Kalshi bonus with as little as a $10 deposit.

2. OG - Highest welcome bonus

There's no doubt that the OG promo code is the best of any prediction market app. New users can grab up to $100 in bonus funds for meeting specific trading requirements. However, you need to trade at least $500 within 7 days to claim the full amount.

Of course, a welcome bonus isn't everything, but OG.com backs up its excellent welcome promo with a platform that is loaded with trading options. OG allows users to trade on sports, politics, culture, and economics. Not only does OG allow users to trade on player props, but the platform also covers sports outside of the Big 4, such as golf, various soccer leagues, college athletics, and F1.

I also love how straightforward the fees are at OG. While other apps have intense algorithms to determine fees for specific trades, OG simply charges between $0.02 and $0.04 for every contract. While this may be more expensive in some instances than what you pay at Kalshi or Polymarket, it's not always the case. And it's nice to know exactly what you're paying and why.

3. Novig - Best for sweepstakes style trading

Novig recently received certification from the CTFC to operate as a prediction market. Interestingly, though, they have retained the dual-currency model from its time as a sweepstakes operator, still offering the sale of Novig Coins. 

Another important factor is that Novig is currently only offering markets on sports. You won't find politics, weather, culture, or finance there. At least, not yet. The selection is somewhat limited, too, with only soccer, MLB, WNBA, tennis, golf, and MMA currently listed. 

One great thing about Novig, though, is that it provides daily bonuses, unlike other prediction markets. As of this writing, I can see a 25% Parlay Boost for World Cup and MLB games, or a 500,000 Novig Cash contest for picking the Golden Boost winner. 

Right now, new users can use the Novig promo code SBR to claim a low-risk welcome offer: Spend $5, Get $50 in Novig Coins. 

4. Gemini - Best for crypto transactions

If you already use Gemini exchange for crypto transactions, then using Gemini Predictions will offer a seamless transition for you. To make predictions, you're using the same app as Gemini exchange, which makes it easy to keep all your assets in one place.

Gemini doesn't have any trade caps, and it makes liquidity easy to spot, with market volume listed below every event. The only real negatives are that Gemini doesn't offer one of the best prediction market promos, and there is limited market selection. While the major sports, and even some minor ones like chess, are covered, there isn't much depth in these categories. Plus, culture markets are very limited.

All of that said, if you're already familiar with Gemini exchange and you want to primarily trade in crypto, Gemini is the best alternative to Kalshi for you.

5. ProphetX - Best new platform

If you're looking for something new, then ProphetX is the place for you. While the platform has been around since 2018, it just received approval from the CFTC to operate as a prediction market platform in June 2026. Previously, it operated as a DFS site.

New traders can use the ProphetX promo code SBR to earn $20 in bonus funds after $10 in trades. While this isn't the largest bonus by any means, needing to trade only $10 is great, considering many leading competitors require $20 or more to max out their bonuses.

ProphetX currently only offers sports markets, but that's likely to change in the near future. We will update this page if markets related to politics, weather, pop culture, or the economy become available.

How Kalshi stacks up to these alternatives

Kalshi is the best-of-the-best when it comes to prediction market apps. However, other apps, especially the four mentioned above, are closing the gap quickly. Here are the areas where Kalshi is still ahead, as well as the ones where Kalshi is starting to lag behind.

Where Kalshi still wins

• No one offers more market coverage than Kalshi. Kalshi allows trading on nearly 20 sports and more than 10 non-sports markets.
• Excellent user interface. While most of Kalshi's alternatives have great mobile apps, none is as simple to use as Kalshi's.
• Liquidity is another area where Kalshi has the edge over most competitors. Because Kalshi is so well known in the industry, you'll rarely ever have trouble filling an order, which isn't always the case with some alternatives.
• Kalshi allows users to contact them and make their own markets. While this is becoming popular at other prediction apps, Kalshi is still the best place to do this.
• Kalshi offers users lots of variety when it comes to transferring money in and out of their accounts. A lot of apps are very limited, sometimes only offering one or two methods, while Kalshi offers plenty including, crypto, PayPal, bank transfer, and debit cards.

Where alternatives beat Kalshi

• Kalshi is only available in 42 states, while platforms like Polymarket and Gemini are available in all 50 states plus DC.
• Kalshi's fees tend to be more complicated and sometimes more expensive than competing apps.
• With a small welcome bonus, Kalshi struggles to compete, as most alternatives offer bonuses between 2x and 5x what Kalshi offers.
• Kalshi doesn't have any ongoing promotions, unlike some prediction platforms that reward existing users for loyalty.

State-by-state availability

Kalshi is one of the more limited prediction market apps, as you'll see from our table below. It's also worth noting that while Underdog Predicts is unavailable in 15 states, other Underdog products are available in all states except Nevada.

Fee comparison: what you actually pay

While some platforms have very standard fees, Kalshi and Polymarket use complicated formulas to determine how much you owe for each contract you purchase. 

Kalshi uses the following formula to determine the fee for each contract purchased: 0.07 × C × P × (1 − P). This means that fees range between $0.07 and $1.75 per 100 contracts, and contracts closer to 50 cents have higher fees than contracts at the extremes.

Polymarket's fee structure is very similar. The formula of Θ × C × p × (1 − p) may not mean much to you, but putting it into simple terms, there are greater fees for contracts priced around 50 cents than there are for contracts closer to $0.01 or $0.99.

OG, Underdog, and Gemini have elected to go a much simpler route, with fees set at flat rates ranging between $0.02 and $0.07. While simplicity may appeal to some, the fees at Kalshi and Polymarket are often smaller than at these alternatives.

Funding methods & payout speeds

The user experience of a prediction market app is very important, but there are many who would argue that withdrawal speed is even more valuable. After you've earned your money, you'll want to know that you can withdraw it in a timely manner. Here's a look at how long it generally takes for Kalshi and the leading apps like Kalshi to payout earnings via various funding methods.

How to switch from Kalshi

Switching from Kalshi to a similar app takes no time at all. This is made easier by the fact that you can have accounts at multiple prediction market platforms at the same time. However, if you're ready to move on from Kalshi and make another app the only platform you use, here's what you should keep in mind.

Resolve open positions

The first thing you're going to want to do before you switch to an app like Kalshi is resolve your open trades. This means selling any contracts that are open, or waiting for your open contracts to resolve after an event goes final.

Withdrawing funds

There is no way to transfer funds directly from Kalshi to another prediction market app. Therefore, you will need to withdraw any money or crypto in your account before you can use it on another platform. This process looks just like any other withdrawal. Unlike switching from one bank to another, you don't need to close your account. Just withdraw how you always have, and the funds will be added to your preferred payout method.

Tax timing

We are not tax professionals, and we cannot offer tax advice. However, when withdrawing, keep your taxes in mind. Because Kalshi is CFTC-regulated and operates similarly to a stock exchange, you will need to pay taxes on any earnings you withdraw. Remember to keep the tax calendar in mind, and reach out to your accountant if you're ever unsure how to move forward.

USDC bridging

If you're using crypto, Kalshi supports USDC bridging. This allows you to move USDC from one blockchain to another. While this will still require you to withdraw your funds from Kalshi, you can use your withdrawal to purchase any of the cryptocurrencies supported by the platform.

Are apps like Kalshi legal in the US?

Yes, apps like Kalshi are legal in the US. All the apps we mentioned above are CFTC-regulated, meaning they operate under federal jurisdiction. That enables you to use Kalshi in Georgia, and other states without legalized sportsbook laws. 

That said, there are some similar apps we recommend you avoid. Here's a look at the legality of apps like Kalshi.

CFTC-regulated

These are the main prediction market platforms that operate in the US. CFTC regulation essentially means that an app has gone through all the legal processes necessary to operate in the US, and they continue to hold themselves to the standards of the governing body. CFTC-regulated apps include Polymarket, OG.com, Underdog, Gemini, and many more, and they are the safest options for those looking to get started at prediction market platforms.

Sweepstakes casinos

Sweepstakes casinos aren't CFTC-regulated, and instead, their legality is up to individual states. Because of this, these platforms tend to be available in fewer states than CFTC-regulated prediction market apps, as many state governments attempt to shut them down. 

Still, these sweepstakes casinos are fully legal in the states where they operate, and they offer an excellent alternative to online casinos, sportsbooks, and prediction market apps.

Offshore/decentralized sportsbooks

We recommend that you stay away from offshore sportsbooks entirely. Many have come under fire in recent years for not paying out winnings or shutting down without giving players their money back. These sportsbooks and prediction market apps do not operate legally in the United States, so if anything happens to your money, there's not much that you can do about it. 

Tax reporting on Kalshi alternatives

Disclaimer: We are not tax professionals, and we cannot provide tax advice. The purpose of this section is to simply make you aware of tax reporting with Kalshi and the best prediction market apps like Kalshi. If you have any specific questions regarding taxes, you should reach out to an accountant.

As of June 2026, there hasn't been any guidance from the IRS regarding prediction markets. So while some platforms, such as Kalshi, will provide you with a 1099-B, others won't. Keep track of your earnings throughout the year, as you may need to go in and calculate your total earnings or losses. This could change in the future if the IRS takes a clear stance on how it wants earnings from prediction markets reported.

Section 1256 treats gains and losses as 60% long-term and 40% short-term, no matter how long you actually held your positions. This is much more complicated than a standard 1099, but it may be able to help you save a lot of money in taxes at the end of the year.

If you primarily fund your accounts with crypto, you will still need to report all earnings on the prediction market app like Kalshi that you use, as well as your gains or losses from your crypto wallet.

How we tested and ranked these apps

To determine the best apps like Kalshi, our team of experts spent at least 5 hours on each platform, diving into payment methods, available markets, user experience, fees, and more. Below, I break down what we did and how each category affects our overall rating of each app.

User experience

I consider this to be the most important factor when testing out an app like Kalshi. There is nothing more frustrating than downloading an app and not being able to figure out how to use it. I want simplicity from the moment I sign up through the moment I withdraw my earnings.

Before providing a rating, our teams of experts register with an app, ensuring that welcome bonuses work and there aren't any confusing elements throughout the process. We then deposit real money and make real trades.

For example, when testing Polymarket, I deposited $10 to earn $20 in bonus funds. I then used those funds to trade on the Spurs as NBA champions. While this trade hasn't settled yet, I've been able to monitor the Spurs' odds, so if the price ever gets to a sweet spot, I'll be able to sell my contracts for a profit.

Available markets and liquidity

Having a plethora of available markets is key to the success of any prediction market app. What makes prediction market apps so enticing, aside from their availability in states where sportsbooks can't operate, is the presence of markets that you won't find at standard sportsbooks.

An app will score high if it has plenty of cultural markets, such as awards shows, politics, and the economy, to go along with a healthy number of sports markets. However, having these markets isn't enough. Apps also must have users who fund liquidity and make it so that trades execute, even in more niche markets.

Security and trust

Every app that we recommend is CFTC-regulated, meaning that they have to adhere to strict standards from the US government. If a prediction market app isn't regulated, then we recommend you stay away. 

Payment methods and withdrawal speed

Options are key for transferring funds to and from your account. Some apps are very limited, such as Polymarket, where you can only withdraw via crypto. Since this method might not be ideal for everyone, Polymarket scores lower in this category than Kalshi, where users have plenty of options for both deposits and withdrawals.

However, payout speed is also very important. The apps that we recommend tend to process withdrawals in 1-3 business days, though if you use crypto for withdrawals, you will often see you funds instantly.

Customer support

To score high in customer support, an app must have active customer service reps available to chat as often as possible. Some apps only offer email correspondence, while others offer a live chat but with AI rather than a real person. We look for apps that have human representatives available to assist you with any questions or concerns you have around the clock.

Red flags: apps like Kalshi to avoid

Prediction market apps haven't see the same influx of offshore or illegal operators that we see in the world of sportsbooks. While all of our options above are safe to use, be wary when registering for other platforms and always keep the following red flags in mind:

• Unregulated platforms should be avoided at all costs
• Watch for lesser-known platforms with a history of insider trading and market manipulation
• If you are a US resident, never use a platform that operates offshore, as you won't have any protections should your funds be compromised

Responsible trading

While prediction markets aren't technically considered gambling, you are still risking your money, and there is a chance that you could end up losing funds. Always keep in mind the risks as well as the rewards when trading. If you find that trading on a prediction market platform is no longer enjoyable, and you feel that you have lost control, reach out to one of the many support lines that are available nationwide.
