No Underdog promo code is required when you sign up to this prediction market site. That’s one less thing to worry about! This is pretty common, as most prediction markets don’t offer welcome bonuses.

Instead, Underdog delivers value in several other ways. Whether it be through its streamlined, easy-to-use mobile app or the huge collection of events where you can buy and sell contracts. Stick around as I break down why Underdog is a top choice for prediction markets.

Does Underdog have a welcome bonus for prediction markets?

No welcome bonus is available for traders at Underdog prediction markets. For a new vertical coming from a prominent site known for fantasy sports and online sports predictions, this is definitely expected. But fret not, a welcome bonus could be added in the future, and should it take place, you’ll be able to spot it in the promotional banners of this page.

In theory, if a welcome offer is ever added, you likely wouldn’t need an Underdog prediction promo code. Instead, you could simply click any of the links in the banners on this page to claim the rewards automatically.

So there’s no Underdog promo code, but even if there were, you’d need to be located in one of the US states where the site is legal. The terms and conditions specifically outline 34 legal states, including some of the most populous areas of the country, like Florida, California, Texas, and Washington. Conversely, some of the most prominent restricted states include:

❌ New York

❌ Pennsylvania

❌ Illinois

❌ Michigan

❌ New Jersey

Underdog is a CFTC-regulated exchange, so these requirements are strictly enforced. You cannot use a VPN or any other form of technology to change your location, and proof of ID and address is required to verify your account.

How does Underdog Prediction Picks actually work?

Prediction markets allow you to buy and sell event contracts based on the outcomes of real-world events. This could be anything from who will clinch the next Super Bowl to whether interest rates will increase at the next Federal Reserve meeting. That said, these events are all based on yes or no questions, as you will be purchasing “Yes” or “No” shares with any event contract.

🤔 How are contracts priced at Underdog?

Unfortunately, you won’t find any Underdog promotions offering special discounts. Instead, the price is set by the market, as the more likely an event is to occur, the higher its implied probability and price. For example, if the market dictates Liverpool FC has a 20% probability of winning the next Premier League Title, the price of event contracts that confirm this prediction will be $0.20.

💰 How are payouts calculated?

When an event finally settles, there are two potential outcomes and payouts, determined by whether you correctly predicted the market. Here’s what you can expect:

  • Correct prediction = you receive a $1 payout for each contract held
  • Incorrect prediction = you receive $0

What I like about this payout system is that it makes it easy to calculate your payout. Simply subtract the cost of each event contract from the $1 payout. Don’t worry, if you’re considering a large number of shares, Underdog will clearly outline any potential profit before you place the order.

📊 Examples of real event contracts

If you caught my recent Underdog Predict review, you will know that this site lets you choose from thousands of potential events. This includes sports, culture, politics, the economy, and more, all in one clean and intuitive dashboard.

Here are a few event examples you can use as guidance:

Event Contract Purchased Price/share Implied probability Potential profit/share
Yes – Seattle Seahawks to clinch Super Bowl LX $0.68 68% $0.32
Yes – Gavin Newsom runs for President in 2028 $0.28 28% $0.72
No – Spain wins the 2026 FIFA World Cup $0.84 84% $0.16
No – “One Battle After Another” wins an Oscar for Best Picture $0.33 33% $0.67
Yes – Kevin Warsh wins nomination as next Fed Chair $0.80 80% $0.20

Download the Underdog Predictions app for live trading

One of the features that makes UnderDog so special is the ability to buy and sell event contracts at any time before the event has concluded. This is especially beneficial for sports like the NBA and the NFL, where minimal changes in the game can drastically change the price of your contracts. By downloading the mobile app or visiting the mobile website, you can quickly and efficiently buy and sell event contracts depending on these changes.

Let's say there’s a sudden change in momentum or a star player gets injured. By going straight to the app, you can manage your positions, selling out to lock in profits or minimize losses. This doesn’t just apply to your existing contracts; you can use it to buy into new ones if you like what you’re seeing.

Sign up for email or SMS alerts for future Underdog promos

There might not be any Underdog Predict promo codes right now, but that doesn’t mean this will always be true. If the brand rolls out new promotions, they’ll most likely announce them through their email or SMS newsletters. You can sign up for these alerts through your account settings, so you’re among the first to know about new offers.

In addition to SMS and email alerts, you can also try following Underdog on social media platforms such as X, Instagram, and Facebook. This is another place you can learn about new promotions, plus you’ll get more general information about updates and announcements.

Understand markets to get more out of your deposits

With no genuine Underdog new user promo for prediction markets, you need to get creative in getting more out of your deposits. Personally, I believe choosing from events you generally understand is the first place to start. If you’re a big sports fan and love to follow the NFL or NBA seasons, starting with markets tied to these sports is a smart plan. Likewise, if you regularly track financial markets, the economics side of Underdog predictions might be a smarter choice.

How can additional research help you even further?

Research is another important part of informed predictions, helping you get even more value out of your deposits. For example, in sports prediction markets where you’re choosing the winner of a match, you could research several statistics, including:

  • Recent form of the teams and key players
  • Previous results when the two teams met
  • Injury reports to see if key players are missing
  • The impact of weather conditions

While this research alone can’t guarantee any results, it does give you a better understanding of which predictions could offer good value.

The importance of responsible trading at Underdog

Traditionally, an Underdog Prediction deposit bonus would provide additional funds to ensure you’ve got even more to trade with. Since that isn’t currently an option, you’ll need to take an even more responsible and careful approach to trading. This includes setting a budget that you can reasonably stick to, and potentially leveraging Underdog’s player control tools, including deposit limits, session reminders, and temporary or permanent self-exclusions.

Does the Underdog referral program work for prediction market traders?

If you weren’t already aware, the Underdog app and website run a referral program for its users, letting you invite your friends for rewards. This works by allowing you to generate a referral code to send to your friends, and when they register and make a $10 deposit, you receive “Program Credits.”

On the surface, the site seems like one of the first actual promotions available to Underdog prediction market traders. However, I read through the entire terms and conditions and noticed something in the fine print. They explicitly state that any bonus funds from the Underdog referral bonus cannot be used for prediction picks, including event contracts traded on Underdog.

Now, I know what you’re thinking. Why not withdraw the Underdog referral rewards and deposit them again to fund your prediction markets account? Sounds like a smart move, but Underdog has also outlined that this is against the rules in its bonus terms. So, for now, you’ll need to wait and see if the referral program gets expanded to include the prediction markets element of Underdog.

My final thoughts on the lack of promo codes for Underdog Markets

Once you get over the initial disappointment that there are no Underdog Predict promo codes or welcome bonuses, this is actually an impressive prediction site. You can buy and sell contracts for a wide range of events, including sports, entertainment, culture, and more. Everything from the way payouts are calculated to trading positions and more is super simple, making it beginner-friendly. At this point, Underdog Markets are definitely a good go-to for you to enjoy your overall experience on the site.

And despite the lack of promotions, you can still get more out of your deposit by implementing a few helpful strategies. This includes picking a market you understand, conducting additional research, and trading responsibly.
