This is perhaps why the app already has a 4.6-star rating based on tens of thousands of user reviews.
While the prediction market selection at Crypto.com might be modest compared to Kalshi and some bigger apps, the main bases are covered. Besides crypto, you can also trade future event contracts on sports, economics, political events, and more.
However, what stands out most about this app is its simple but effective interface. The prediction markets are easy to find, follow, and understand. This makes the app ideal for beginners and experienced traders who are looking for a streamlined process. On the other hand, if you like more attention to detail, you may miss some of the interactive trackers and graphs that apps like Kalshi offer.

Polymarket is probably the second most famous prediction market brand after Kalshi, and it has the substance to back up its reputation. This app probably has the most diverse market selection around, for sports, politics, climate, and everything in between. When it comes to crypto trading, it offers the most short-term and high-frequency markets around, including the BTC 5-minute Up/Down prediction.
When it comes to fees, Polymarket keeps things much simpler than Kalshi’s complex expected profit fee structure. There’s a fixed taker fee for each type of contract, such as 0.07 for crypto predictions. Moreover, there’s also a maker rebate system that can get you up to 20% for making a trade on the market.
In terms of customer service, Polymarket has a decent Help Center, online live chat, and a responsive email. Additionally, there is a US phone number that you can call if you wish to speak with an actual human being.

Robinhood’s prediction markets hub is available through its regular trading and investing app. While not a standalone product, the prediction market is powered by Kalshi and is therefore extremely reliable. However, it does have limitations in its prediction market offering compared with Kalshi and other dedicated prediction market platforms.
However, this low selection of markets means that it hasn’t spread its trader base too thin. As a result, you should find decent market volume and liquidity, particularly for sports predictions. The prices for event contracts on Robinhood tend to remain fair, rarely moving away from the 1:1 ratio with the chance percentage.
The most appealing thing about prediction markets on the Robinhood app is the fee structure. Not only is it simple, but it’s also cheap, as there’s a flat rate of $0.02 on all event contracts. As long as you’re happy with the modest range of prediction markets, this is definitely the cheapest app to trade on.
Legality-wise, it’s the same story as Kalshi. The prediction market is a derivatives platform that’s CFTC-regulated and legal in all 50 states. That could change in the future, but at the time of writing, the information is accurate.

Now that we’ve reviewed and rated the top three prediction market apps like Kalshi, we’d like to give you a bit more insight into how we rate them. Below, we’ve listed the key criteria that we consider when reviewing and testing a prediction market app:
Prediction market trading in the United States is only legally available in CFTC-regulated exchanges, so this is the first thing that we look for. After that, we check for any state restrictions and exclusions before testing the security protocols like 2FA and security questions.
While the user rating is an indicator, we always test the app for ourselves to see how user-friendly it is. Ideally, we’re looking for a balance of simple navigation for beginners, twinned with high-level features for experienced traders.
Perhaps most importantly of all, we look at the range of prediction markets offered on the site. Sport, finance, and politics prediction markets are the core of any good app, but popular niche markets like crypto, climate, and culture are also important to offer.
After we’ve looked at the prediction markets, we turn our attention to purchasing the event contracts. The best apps have a selection of trading options, including buying in dollars, contracts, and limit orders.
We always check the selection of deposit and withdrawal methods, alongside the limits and fees for each one. Ideally, we’re looking for a selection of fiat and cryptocurrency options.
Some prediction market apps have their own native crypto token that’s used for trading. For example, Polymarket as pUSD (Polymarket USD), which is an ERC-20 token on the Polygon chain that’s tethered 1:1 with USDC.
Prediction market sites work by matching equal counterparts for prediction market event contracts and take a trading fee. Low fees are obviously ideal, but a clear and simple fee structure is also a bonus.
While it’s essential to cover the basics and do them well, special features are what can make an app stand out from the pack. For instance, the transparent Order Book feature on the Polymarket app shows the real-time trading volume, which helps assess market liquidity.
If you encounter issues, it is always good to know that you can quickly and easily find the help that you need. Besides a comprehensive Help Center, we always test the customer service communication channels and rate them in terms of responsiveness and helpfulness.
We don’t want to sit in an echo chamber, so we also take other users’ and experts’ opinions into account to assess what the wider public thinks. This gives us a more well-rounded view of how the trading app and brand are perceived.
The process of creating your account will be slightly different depending on whether you’re using Crypto.com or similar apps to Robinhood. However, he’s a board step-by-step guide to walk you through the process:
Pick – Read our reviews and select the right prediction markets app for you
Visit – Follow the banners on this page to your platform of choice
Download – Download and install the prediction markets app
Begin – Tap the “Sign Up” button to get started
Login – Create a username and password
Contact – Enter a valid email address and US phone number
Verify – Upload the required documents to verify your account
Accept – Read and accept the T&Cs
Deposit – Funds your account using your preferred deposit method
Trade – Browse the prediction markets and start trading Yes/No event contracts
Even contracts can come in a few different forms, depending on the type of prediction market that you’re looking at. To give you a simple example, here’s how a simple Yes/No-style binary sports event contract looks on Robinhood for an MLB game between Cleveland and Detroit:
| 📈 Event contract | 💲 Price |
|---|---|
| Cleveland: | $0.38 |
| Detroit: | $0.62 |
The price of the event contracts is always between $0.01 and $1.00, and is based on the percentage probability the market has given the outcome of happening. In this case, it works as follows:
In a similar way to sports wagering, you need to make a correct prediction to receive a payout. However, rather than placing a bet against the house, you’re buying event contracts on your predictions, which can only be done if there are traders willing to sell those contracts.
The advantage of this is that the probabilities and prices are a 100% accurate and transparent reflection of the true market opinion. Prediction market apps charge trading fees for matching buyers and sellers. Unlike sportsbooks, they don’t manipulate the odds to add a commission for their own profit.
Once a prediction market has been resolved, the correct event contracts for the correct prediction close at $1.00, with the opposite numbers closing at $0.00. In simple terms, you make a profit if you make a correct prediction and a loss if you are incorrect.
To use the above sports prediction market example from Robinhood again, let’s say that Detroit won the match. This would resolve the market as “Detroit”, meaning:
If you had purchased Detroit contracts at $0.62, you’d make a $0.38 profit on each one:
On the other hand, if you had purchased Cleveland contracts, you’d lose out on the entire outlay plus trading fees.
Most prediction market apps give you three options when it comes to purchasing event contracts for their prediction markets. To explain these below, we’ve again used the above baseball prediction market example as a reference point.
This straightforward option allows you to type in the number of contracts that you wish to purchase and instantly calculates your cost. For example, if you wanted 100 Detroit contracts at $0.62 each, the cost would be $62.00 + fees ($0.62 x 100 = $62.00).
Alternatively, you can enter the amount in USD that you would like to spend. Though there will usually be a trading fee on top, buying in dollars is easier for budget management, but it will almost certainly result in you owning fractional contract shares. For example, if you spent $100 on Detroit contracts at $0.62 each, you’d get 161.29 contracts ($100 / $0.62 = 161.29).
Like any form of trading, prediction markets are extremely risky and exposed to multiple elements, including market liquidity, price volatility, and negative slippage. The expected price of the event contract can often end up vastly different from the price that you expected to pay. To mitigate the risk of these, you can place a limit order with a maximum price-per-contract that you’re willing to pay. If the trade executes above this price, your purchase order will automatically be cancelled.
The sports prediction market example that we used above is a binary event contract, where there are two outcomes. In this case, it’s Team 1/Team 2, but you also have Yes/No contracts and Up/Down.
Binary contracts aren’t the only types available, as there are two forms that you’d find: categorical and scalar. Here’s a brief overview of how all three work:
In summary, there are many other prediction markets that are CFTC-regulated and offer similar event contracts to Kalshi. You can trade on future outcomes for events including sports, crypto, climate, and more.
