My First-Hand Experience Using Underdog Predicts

I knew Underdog was a big name in the Daily Fantasy Sports world, but when I saw they had become a CFTC-certified prediction market platform under the name Underdog Predicts, I had to check out their latest offering. The first big draw to their app I found is the massive welcome offer you can claim using the Underdog Predicts promo code SBD to unlock a 50% deposit match up to $1,000.

Going beyond what is one of the best prediction market sign-up bonuses, there is a lot to like about Underdog Predicts. Read on to see what I learned during my first-hand experience using Underdog Predicts.

First-Hand Underdog Predicts Review and Takeaways

Signing up and claiming the Underdog promo code SBD was a breeze. They just ask for some key personal details like your name, date of birth, home address, and email address to verify your identity. Within a few minutes, I had my account set up, deposited some funds, and claimed my deposit match. Welcome offers don’t get much easier than this. They rewarded me for doing something I was going to do anyway.

Coming from their DFS app, it does take a little time to get used to how prediction markets work, but once you get a feel for it, it makes trading so much easier.

If you wanted to trade on the Bengals to beat the Texans this weekend, you would see Underdog Predicts lists the Bengals as having a 42% implied win probability. This means that each contract for the Bengals to win would cost $0.42, and if they do win, you would get $1 back for every contract you own, netting you $0.58 per contract. However, if the Texans win, your stake would resolve to $0, and you would get no money back from your position.

To make it easier to transition to using a prediction market, Underdog Predicts also shows the odds in the sportsbook standard +/- format. You also have the ability to see the odds as a multiplier or percentage.

It is clear Underdog Predicts knows this might be the first time some of their users have traded on a prediction market, and they took the steps to make the transition as easy as possible.

The User Experience of the Underdog Predicts App

With all of their experience as a DFS platform, they knew how to make Underdog Predicts look and feel great. It didn’t take long to feel at home on the app, and navigating to markets on my favorite team only took a few taps before I was looking at player props for this week’s slate.

Once you find the market you want to trade on, you can watch in real-time as money comes in and the lines shift as traders pile on one side of an outcome in this peer-to-peer exchange.

Underdog Predicts made it easy for me to find player prop markets with plenty of liquidity. Once you scroll past the Game Lines, you are greeted with a Popular Markets section. Just tap on the market you want, and the app opens up a screen with that player’s props, futures, and complete game log to help you make a decision.

To place your trade from here, select the side of the outcome you want, enter how much you want to spend on contracts, and hit submit. Once placed, follow your orders using the “Track” button at the bottom of the screen, and if things are looking good early, even sell your position before it resolves to lock in any gains.

Understanding Underdog Predicts Fees

Underdog Predicts has one of the simpler fee structures when it comes to placing a trade on a prediction market. Unlike other platforms that require some complex math or knowing which market has a higher fee than others, Underdog Predicts charges a flat 2¢ per contract fee.

This means if you purchase 10 event contracts priced at 50¢, you will pay $5.00 for the contracts and an additional 20¢ in fees. You should factor this in when purchasing more expensive contracts because that fee will eat into your potential winnings as the cost creeps closer to 99¢.

Underdog Predicts covers deposits with most of the standard options users are accustomed to, including Credit Card, Debit Card, Venmo, PayPal, Google Pay, Apple Pay, and Trustly. While there are no fees for depositing money into your account, they do require a minimum of $10 to make a deposit.

Your options are a little more limited for withdrawals. The simplest methods are to use Venmo, PayPal, or Trustly, which have no special parameters to complete the action. You can withdraw to Debit Cards; however, you can only do so if the card was previously used to deposit money. They also do not charge a fee for withdrawals, so the funds you see in your wallet on the app are yours to keep.
