What is Underdog Predict?

Underdog Predict is a mobile predictions site that lets you trade contracts on the outcomes of real sports events, among other markets. While the mobile app is what you mostly use, the site is also desktop-friendly.

We love its user-friendly interface with a simple Yes/No format for predictions. Funding your account and claiming winnings is easy via debit card, Trustly, or Apple Pay within the app. Underdog Predict offers several prediction categories beyond sports, such as politics and entertainment. Markets are easy to access, but the cherry on top is the promotions and bonuses for repeat users. Overall, Underdog Predict is a great site for casual users seeking simple prediction mechanics.

Why do traders look for apps like Underdog Predict?

Okay, so if the site is that solid, why do traders seek out prediction market apps like Underdog Predict?

Different users want different features

Variety really does make a huge difference, especially when it comes to prediction market platforms. At first, you might be completely satisfied using a sports-focused app like Underdog Fantasy, but over time, those options can start to feel a little limited if you want access to broader event markets like crypto, politics, entertainment, or global news.

Different users also look for different things depending on their experience and trading style. Some people care more about bigger payout potential and fast-moving markets, while others simply want a platform that feels easy to understand from day one. That’s exactly why exploring multiple platforms can be worthwhile since each one brings something slightly different to the table.

Where alternatives may outperform

While Underdog Predict has plenty of fortes, the site may fall short in terms of lower fees, better liquidity, and more frequent market launches. Platforms with wider geographical access will also naturally reach more players. You may also want a taste of apps like PrizePicks, with a more polished UI and things like in-app chats and customizable dashboards. In short, Underdog Predict can’t be the best in everything.

Best sites and apps like Underdog Predict reviewed

So, what other apps are like Underdog Predict? Loads exist, but these are the top 5 alternatives worth your time. These are:

Crypto.com – Quick payments using crypto

Crypto.com isn’t a small-time prediction site and is found in over 100 countries, including the USA. You can fund your account using more than 400 cryptocurrencies, and yet also deposit using fiat.

The site covers sports prediction markets, where you can guess winners for basketball and football. Other markets include banking, stocks, and, of course, predicting crypto outcomes. Its mobile-first design allows for convenient trading from any location. Crypto.com has loads of incentives for high-tier trading, which may tilt the playing field against casual users.

Sponsored by Crypto.com – Not investment advice. Trading prediction markets and crypto involves risk, including potential loss of your stake. Consider your risk tolerance before participating. Crypto.com connects U.S. users to CDNA (regulated by CFTC) for derivatives trading. CDNA membership required. Trading may not be suitable for all—you could lose your entire investment plus fees.

Polymarket – Best for sports predictions

Polymarket is another excellent prediction site that accepts any crypto wallet compatible with the Polygon network. Coinbase and MetaMask are good examples and easy to set up. The site boasts high liquidity, especially for markets like politics, top sports and crypto.

Major events like geopolitics or the FIFA World Cup tend to have higher liquidity, but it spreads thin with niche events. Polymarket is regulated by the CFTC, so it can legally operate in the US. However, some states, like Nevada, have challenged this ruling and don’t accept it. Be sure to verify eligibility before signing up.

Robinhood – Best mobile app

PrizePicks – Best for fantasy sports

PrizePicks is a top choice if you’re looking to predict outcomes for fantasy sports, period. You won’t find other markets here. Its sports-first focus means it channels its efforts into quality sports predictions, complete with promotions and exciting incentives.

The site uses Pick’em-style gameplay with higher/lower formats. Instead of making predictions based on complex odds, you decide if a certain outcome will be higher or lower than the projected stats. For example, you can win by correctly guessing if the total scores for a match will be over or under the set number. It covers popular leagues like the NFL and NBA.
