Underdog Promo Code: No Welcome Bonus

Underdog Sports has been one of the fastest growing names in daily fantasy sports since launching in 2020, known for its Best Ball and Pick'em products that have built a loyal following among sports fans who want something more engaging than just watching a game. In September 2025, Underdog launched Underdog Predict, a prediction market product powered by a partnership with Crypto.com Futures North America, the same CFTC regulated exchange infrastructure that sits under Crypto.com and Fanatics Markets.

No Welcome Bonus

Predict

Must be 18 years or older and have a legal, U.S. residential address within the applicable state, D.C., or U.S. territories. Not available in AZ, IL, MA, MD, MI, MT, NJ, NV and OH.

In March 2026, the platform took a significant step forward by acquiring Aristotle Exchange DCM and DCO, two CFTC approved entities that now give Underdog the ability to list and clear its own event contracts independently. That acquisition means Underdog Predict is no longer simply an intermediary passing trades through a third party exchange. It now runs its own regulated clearing infrastructure under federal oversight, operating as a registered Futures Commission Merchant through the entity UDM Services LLC.

The prediction markets section lives inside the main Underdog app alongside fantasy and pick'em, which is both its biggest strength and its clearest trade off. For the millions of people who already use Underdog every week during sports season, getting into prediction markets is as simple as tapping a new tab. For traders coming purely for event contracts, the dual product setup means the platform was not designed around them from the ground up.

Getting From Sign Up to First Trade

Underdog Predict lives inside the main Underdog Sports app. If you already have an Underdog account from fantasy or pick'em, you do not need to create a new one. You simply update the app, navigate to the Predict section, complete identity verification if you have not already, and you are ready to go. For new users, the signup process covers your full name, date of birth, home address, email, and Social Security number. You must be 18 or older and physically located in one of the 31 supported states plus Washington D.C. at the time of trading.

Once inside, you fund your account via debit card, online banking through Trustly, or Apple Pay. The minimum deposit is $5 via debit card. There are no deposit fees from Underdog's side. Withdrawals are available via debit card or online banking with a minimum of $10, though if your balance is below $10 you can still withdraw the full amount. Withdrawals carry no fee and typically process within one to five business days.

Each market is a Yes or No question. You browse available contracts, pick your outcome, decide how many contracts you want, review the price and potential payout, and confirm. The price you see reflects the market's current view on how likely that outcome is. A contract at $0.65 means the market thinks there is a 65% chance the event resolves Yes. If you are right you collect $1 per contract. If you are wrong the contract expires at $0.

You can close your position before the market settles by selling your contracts at whatever the current price is, locking in a gain if things moved your way or cutting a loss if they did not. When a market closes, contracts settle automatically. Winning contracts pay $1 per share to your account balance with no settlement fee.

A Bit of History

Underdog Sports was founded in 2020 by Jeremy Levine, who serves as Co-Founder and CEO, and Marcus Robinson, who serves as Co-Founder and COO. The company is headquartered in New York City. Underdog Sports built its reputation through its Best Ball and Pick'em fantasy products before moving into prediction markets in September 2025 through a partnership with Crypto.com Derivatives North America. In March 2026 the company acquired Aristotle Exchange DCM and DCO, two CFTC approved entities, giving Underdog Predict its own regulated exchange and clearing infrastructure through the entity UDM Services LLC. The platform is currently available in 35 states plus Washington D.C., with sports contracts blocked in states that have legal sports betting. The minimum age to participate is 18. All trading is in USD with no crypto wallet required.

Everything You Can Trade and What Makes It Stand Out

Market Categories

Sports: NFL, NBA, MLB, NHL, WNBA, NCAAF, NCAAB, MMA, boxing, golf, soccer including the 2026 World Cup, tennis, and more. With over 25 sports covered, this is one of the widest sports catalogs in the regulated prediction market space. Live in play trading is available across major events, letting you react to what is happening on the field in real time.

Politics: U.S. elections, congressional control, presidential decisions, and major legislative developments. State governor races and other down ballot contests are also covered.

Economics: Federal Reserve rate decisions, inflation data, unemployment reports, and macro financial outcomes. Well developed for a platform that was sports first at launch.

Culture: Entertainment milestones, award show outcomes, social media and pop culture events.

Weather: Hurricane landfall contracts and other measurable environmental events. A newer category that has attracted more engagement than expected.

Global Geopolitics: International affairs and political developments outside the U.S., an area where Underdog has moved more quickly than some competitors.

Trading Model

Order Book Exchange: Peer to peer contracts through CDNA and Underdog's own exchange infrastructure

Binary Contracts: Every market resolves at $1 (Yes) or $0 (No)

Live In Play Trading: Available for sports markets during events

Multi Team Picks: Combine up to four team picks from different games into a single contract position

Combo Entries: Unique to Underdog, combine a prediction market contract with up to eight fantasy pick'em selections in a single entry

Market and Limit Orders: Both available through the order flow

The Combo Feature

The combo entry is genuinely one of the most original features in the prediction market space. No other platform lets you combine an event contract with a fantasy pick'em selection in the same entry. For Underdog's primary audience of fantasy sports users, that crossover creates a type of engagement that feels natural to how they already think about sports. You might combine a contract on which team wins with a fantasy selection on a player going over their points total, turning two separate views into a single position. It is not a feature that every prediction market user will want, but for sports fans already inside the Underdog ecosystem it adds real variety.

The live in play experience is another area where Underdog holds its own against competitors. Being able to trade contracts as games unfold means you can react to momentum shifts, early injuries, or scoring runs rather than being locked into your pre game view.

What Is Moving Right Now

Most Active Markets

Underdog Predict's most traded contracts in 2026 have included:

• 2026 FIFA World Cup group stage and knockout round contracts
• NFL and NBA playoff outcome contracts
  Federal Reserve rate decision markets
• U.S. midterm election and congressional control contracts
• 2026 hurricane season weather contracts
• Global geopolitical event contracts

Where Volume Is Strongest

Sports is the dominant category by a clear margin. The World Cup in 2026 generated record breaking volume on Underdog Predict, reflecting both the platform's sports first audience and the scale of global interest in the tournament. NFL and NBA markets carry the deepest order books during their active seasons. Economics and politics markets see steady participation from users who follow data releases and election cycles.

What Moves Prices Fastest

Prices shift most sharply around:

• Live sports events during in play trading windows
• Unexpected team news or injuries before major games
• Fed meeting days and scheduled economic data releases
• Breaking political news and election night results
• Major weather events and storm tracking developments

Most Active Categories

Sports, Politics, Economics, Culture, Weather · Geopolitics

What Trading Actually Costs

Trading Fees

Underdog Predict charges $0.02 per event contract. This applies when you open a position and again when you close it before settlement, making the full round trip cost $0.04 per contract for trades you exit early. If you hold a winning position through settlement, only the opening fee applies since there is no settlement fee on winning contracts. For users placing occasional trades on major events, the $0.02 fee is small enough to feel almost invisible. For active traders who frequently open and close positions across many markets, those costs accumulate and are worth factoring in before deciding on trade size.

The $0.02 fee puts Underdog in line with Robinhood on a per contract basis, and comfortably below FanDuel Predicts' 2% payout model. It is higher than ForecastEx's $0.01 per contract for traders working at serious volume.

Deposit Fees

There are no deposit fees from Underdog's side for debit card, online banking, or Apple Pay. Your bank may apply its own charges depending on the method.

Withdrawal Fees

Withdrawals carry no fee. The minimum withdrawal is $10, though users with a balance below $10 can still withdraw the full amount. Processing typically takes one to five business days.

No Welcome Bonus for Predict

It is worth being upfront about this: Underdog Predict does not currently offer a dedicated welcome bonus for new prediction market users. There are no promotional credits, deposit matches, or trading fee waivers specific to the Predict product. The platform's fantasy sports sign up offer, play $5 get $50 in bonus entries, is available for new users but applies only to DFS and pick'em activity, not to prediction market trading.

What It Is Like Day to Day

Finding Your Way Around

Underdog Predict sits inside the main Underdog app under its own dedicated section, clearly separated from the fantasy and pick'em products so the two experiences do not bleed into each other. The home screen surfaces trending markets, upcoming events, and live contracts at the top. Category tabs let you filter by sports, politics, economics, culture, and weather quickly. Individual market pages show the current price, available liquidity, and a brief description of the contract terms and settlement rules. Real time price updates work smoothly without lag even during high traffic moments.

For Someone New to Prediction Markets

If you are already an Underdog fantasy user, the Predict section will feel immediately familiar in terms of app design and navigation. The Yes/No contract format is explained clearly on each market page and the order flow is simple enough that most users figure it out within the first trade. For someone completely new to both Underdog and prediction markets, the onboarding is less guided than platforms like FanDuel Predicts or Fanatics Markets that include dedicated tutorial sections. You figure it out as you go, which works fine for sports markets but may require a bit more reading for economics or geopolitics contracts.

The Combo Entry in Practice

The combo feature shows up as an option when you are building a fantasy pick'em entry. You can add a prediction market contract to your pick'em selections before submitting the full entry. In practice it creates a combined style structure where both the fantasy performance outcomes and the prediction contract outcome need to resolve correctly for the full payout. It is a creative use of the platform's dual product setup and one that no competitor currently matches.

Mobile vs Desktop

Underdog Predict is a mobile first product. The app is available on iOS and Android and performs well even during busy live events. There is no full desktop trading interface, which is a real limitation for users who want a larger screen to manage multiple open positions at once. The mobile web version of the site offers basic functionality but the app is the intended experience.

Support

Customer support is available through in app chat, email, and a help centre that covers account setup, deposits, prediction market mechanics, and settlement rules. The support infrastructure benefits from Underdog Sports' existing customer service operation built across the fantasy products. Response times through in app chat are generally reasonable. There is no phone support, which puts it in line with most prediction market competitors in this series.

How Much Is Being Traded

Underdog Predict launched in September 2025 and has grown its market activity quickly, driven significantly by the 2026 World Cup which generated record breaking volume on group stage and knockout contracts. The platform's sports first audience means sports contracts carry the most active order books by a clear margin.

Exact weekly volume figures are not publicly reported, but the combination of Underdog's large existing fantasy user base and the broad 25+ sports catalog gives the platform a natural traffic engine that pure prediction market startups have to build from scratch. Economics and politics markets see growing engagement but are still at lower volumes than the sports section.

Liquidity is below Kalshi on most comparable markets. Underdog and Kalshi do not share order books so prices on the same event can differ. For casual users placing smaller trades on mainstream sports events, the depth is sufficient. Traders looking to move larger positions at tight prices will notice the difference more on economics and political contracts where order books are thinner.

The March 2026 acquisition of Aristotle Exchange's own DCM and DCO infrastructure is expected to support liquidity growth over time by giving Underdog more direct control over how markets are structured and how participants interact. How quickly that translates into deeper order books remains to be seen.

The Brand, What Users Say, and Where It Fits in the Industry

Coming From a Place of Trust

Underdog Sports is one of the most liked brands in daily fantasy. Its Best Ball and Pick'em products have built genuine loyalty among sports fans who appreciate the platform's product quality and how it treats its users. That reputation follows the Predict product in a way that benefits it from day one. Users who already trust Underdog with their fantasy activity are meaningfully more likely to try its prediction markets than they would be to sign up for a platform they have never heard of.

The Aristotle Exchange Acquisition

Acquiring Aristotle Exchange DCM and DCO in March 2026 was a notable move that did not get as much attention as it deserved. In one deal, Underdog went from an intermediary relying entirely on Crypto.com's infrastructure to a platform with its own federal exchange and clearing licences. The long term implication is that Underdog now has the ability to expand its prediction market infrastructure, build deeper market integration with its fantasy products, and operate more independently as the regulatory environment evolves.

No Major Controversies

Underdog Predict has been live since September 2025 and has not been at the centre of any significant market resolution disputes or regulatory incidents. The platform's biggest ongoing challenge is the state availability patchwork and the absence of a dedicated prediction market welcome offer, both of which come up consistently in user feedback.

User Feedback

Reviews across platforms consistently praise the app design, the sports market coverage, and the combo entry feature. The most common criticisms point to the lack of a welcome bonus, the limited deposit methods, and the thinner liquidity on non-sports markets. Users who approach Underdog Predict as an extension of their fantasy activity tend to rate it more positively than those who compare it directly against dedicated prediction market exchanges like Kalshi.

Community

Underdog has an active community built around its fantasy products on Discord, X/Twitter, and Reddit. That community provides a large informal audience for prediction market discussion, though dedicated Predict specific channels are still developing. The platform does not have a separate prediction market Discord or forum at this point.

How It Compares to the Competition

Underdog's clear advantages are the combo entry feature, the 25+ sports catalog, and the brand trust it carries from the fantasy side. Its main limitation compared to most competitors is the 31 state footprint and the thinner liquidity outside sports.

So Should You Use It?

If you are already an Underdog Sports user, the answer is straightforward. The Predict section is already in your app, getting started takes a few minutes, and the combo entry feature alone is worth exploring if you run pick'em entries regularly. The 25+ sports catalog, live in play trading, and geopolitics and weather categories give the platform genuine depth beyond what most people expect from a fantasy app expansion.

If you are coming to prediction markets fresh and Underdog is not already part of your routine, the case is more refined. The 31 state footprint means you need to check availability first. The absence of a welcome bonus and the relatively thin liquidity outside sports mean you are not getting the best possible experience for non sports trading. Kalshi gives better depth on economics, politics, and cultural markets. Polymarket goes deeper globally. OG gives you parlay functionality and a 49 state sports footprint.
Where Underdog Predict earns its place is in the overlap between fantasy sports fans and prediction market traders, a group that is larger than most people realise and one that no other platform has served as deliberately.

Works well for: Existing Underdog Sports users who want to add prediction markets to their activity, sports fans who want a familiar app experience with live in play trading, users in California, Texas, Florida, and other large states without legal sports betting, anyone who wants the combo entry feature to mix prediction markets with fantasy pick'em.

Probably not the right fit for: Users in New York, New Jersey, Illinois, Pennsylvania, Ohio, or Michigan where the platform is currently unavailable, traders who primarily want economics or political market depth, anyone who needs desktop trading or a broader range of deposit methods, users who want a dedicated welcome bonus before getting started.

⭐ Overall Rating: 7.3 / 10

A strong sports focused prediction market for the fantasy crowd, still building the depth and state coverage to compete at the top end.
