Best Apps Like Underdog Predict 2026: Top Underdog Underdog Predict Alternatives

First up – what are the ins and outs of Underdog Predict?

Let’s start today’s guide by exploring the ups and downs of Underdog Predict itself.

Generally, we’ve always felt that Underdog Predict – which was launched by Underdog Sports Holdings Inc in September 2025 as a derivatives-style prediction trading platform – is one of the best prediction markets apps around. Particularly if you’re more interested in sports markets than other types of events.

In our view, the app offers comprehensive market coverage, good US availability and intuitive iOS and Android apps. However, it might not be the best fit for everybody.

Here’s a closer look at the app’s key features, as well as how and why we think alternative apps like Underdog Predict might sometimes be worth considering instead.

Trading derivatives involves risk and may not be appropriate for all. For more information visit: https://www.nadex.com/rules and https://underdogfantasy.com/rules. For Crypto.com Predictions, the term “pick” refers to a product traded on CDNA.

Next – which other apps like Underdog Predict might be worth checking out?

Alternative prediction market apps that we think will appeal to fans of Underdog Predict include those currently offered by Kalshi, Polymarket and Crypto.com.

Here’s a quick look at how these three brands, their features, apps and state by state availability, compare:

A closer look at the best apps like Underdog Predict…

While we believe Underdog Predict has a lot going for it, we also think alternative apps like Kalshi, Polymarket, and Crypto.com are equally worth checking out if the idea of buying and selling “yes” and “no” contracts tied to future event outcomes is something that interests you.

Here is a closer look at what these three prediction trading platforms have to offer:

Kalshi – best for sports market coverage

Kalshi: Pros and Cons

• Find markets via search facility
• Extensive range of prediction markets
• Clear fees system
• Large help center

• Limited promos for existing customers

Kalshi offers opportunities to trade “yes” and “no” contracts across a wide variety of sports markets, including football, basketball, golf, soccer, NHL, tennis and more, making it very comparable to Underdog Predict. That said, the app’s coverage of other popular markets isn’t quite as extensive here as what you’ll find on, say, Crypto.com or Polymarket.

The brand’s affiliate, Kalshi Klear LLC, is CFTC-regulated. Meanwhile, Kalshi itself offers iOS and Android apps – which currently both have high 4.7 star ratings on the App Store and Google Play, with more than 100,000 reviews logged on each. We especially like Kalshi’s easy to read dashboard, and single click tabs for “Elections”, “Politics”, “Culture” and other key markets. While we were impressed to see a $25 refer a friend bonus advertised here at a time when Underdog Predict wasn’t displaying any similar promotions.

Polymarket – best for market variety

Polymarket: Pros and Cons

• Plenty of prediction market topics
• Trending and breaking areas of interest
• Lots of predictions in all major subject areas
• User-friendly site design

• Gradual US rollout

Polymarket advertises itself as “the world’s largest prediction market”. And we tend to agree that when it comes to market breadth and variety, Polymarket tends to shine brighter than Underdog Markets, or other similar prediction trading apps. It offers particularly extensive coverage of geopolitical events, such as global elections, for example. As well as event contract trading opportunities across potential tech industry business outcomes, and weather forecast predictions.

The brand’s official iOS and Android apps aren’t quite as highly-rated as those offered by Kalshi. But we found Polymarket to be incredibly easy to navigate when compared to its other competitors, thanks largely to its color-coded “yes” and “no” buttons, intuitive search engine and logical filter options. Sadly, however, Polymarket wasn’t advertising a welcome bonus at the time of writing. Although they do have a “Liquidity Rewards Program” that rewards traders for especially competitive limit orders.

Crypto.com – best for politics and economics

Crypto.com: Pros and Cons

• Sports, elections, culture, and economics markets
• Low commission for trading
• Supports USD and cryptocurrency payments

• No crypto prediction markets

Crypto.com is a full service trading platform that now offers prediction trading across various popular event markets. However, unfortunately, the site’s widely advertised welcome bonus is not applicable to event contract traders at the time of writing.

On a brighter note, Crypto.com’s highly rated iOS and Android apps are available in English and more than 20 other languages, and cover dozens of different prediction trading markets, including popular and more niche options. Meanwhile, Crypto.com is secure, too – all its prediction trading opportunities are facilitated through Crypto.com Derivatives North America (CDNA). While CDNA itself is regulated by the CFTC. As it stands, we think the brand’s coverage of politics and economics markets is particularly good when compared to the app’s competitors. While we also like how frequently the contract options available are updated.

How to sign up with apps like Underdog Predict

Before registering an account with any of the prediction trading platforms we reviewed above, we’d highly recommend reading up on how event contract trading works, the potential risks involved, and your preferred operator’s state by state rules and eligibility requirements.

In a nutshell, these apps let you trade “yes” and “no” outcomes on future events (such as whether Donald Trump will be re-elected), by purchasing individual contracts that will pay out at $1 each if you’re correct, and $0 each if you’re not. Contract prices fluctuate according to the market, risk is always involved, and there’s never any guarantee of winning anything. While of course, the rules, regulations and acceptance policies set by prediction trading hubs can vary significantly from brand to brand, as per our table above.

Nevertheless, those of you in eligible US states can typically sign up with Kalshi, Polymarket or Crypto.com by following some variation of these general registration steps:

1. Click our links here to reach your preferred brand’s website – be sure to do this from a smartphone or tablet if you want to trade via their app.

2. Tap to download the operator’s iOS or Android app, depending on your device.

3. Enter your email address, or register via your Apple or Google account if this feature is offered.

4. Provide your name, DOB, address and the last few digits of your Social Security Number (SSN) to pass any security checks.

5. Upload some photo ID and proof of address if these are also requested to satisfy the app’s Know Your Customer (KYC) requirements.

6. Read and accept the app’s prediction trading T&Cs – paying special attention to any state-level rules.

7. Add a payment method to fund your account – both fiat and crypto options may be available.

8. Start browsing the prediction markets offered, and trading “yes” and “no” event contracts.

Final thoughts – consider these apps and sites like Underdog Predict today

We think Underdog Predict offers a fun and unique way to participate in your favorite sports, by trading derivatives-style event contracts tied into sports events. While we also like the fact the brand offers intuitive iOS and Android apps, as well as options to buy and sell “yes” and “no” contracts across other popular, real-world events markets, too.

Having said that, Kalshi, Polymarket and Crypto.com each offer similar features and market coverage. And, in some cases, these alternatives might make for better options for you, depending on which prediction markets you’re most interested in, and where in the US you are located.
