My take on the welcome bonus
“Underdog has two distinct welcome bonuses for players to take advantage of. New users who use our promo code CORG can claim a 50% first deposit match welcome bonus. This offer requires users to make a $10 minimum deposit. New users are also eligible to take advantage of the Keep Your Million promotion. This is an offer which has users start with a virtual $1,000,000 pot. They'll then answer 20 questions and keep whatever's left in their pot based on their responses.”
- Two distinct welcome bonuses are available to new users
- The deposit and entry requirements are simple and easy to follow
- The $10 minimum deposit is relatively low
- Withdrawals are free and the stated processing time is typically 48 to 72 hours
- This specific promo is not available everywhere Underdog operates
- Some users can only access to Drafts, and contest formats can differ depending on location
How to sign up at Underdog and claim the bonus
Use our Claim Bonus button to visit the Underdog website and start the registration process. Enter the Underdog promo code CORG during registration.
Enter your details, complete account setup, and submit all required verification details.
Make a minimum deposit of $10, and you will receive a 50% first deposit match welcome bonus. You will then be eligible to enter the Keep Your Million promotion.
"If your goal is to move through the offer cleanly, double-check that you meet the qualifying steps and that you’re actually using any bonus credits when entering contests. That helps avoid the common mistake of spending cash while promotional credit goes unused."
- Start with $1,000,000: Every player begins the game with a virtual $1,000,000 pot.
- Answer a player pick question: You'll be shown multiple picks, like "Will Tarik Skubal have HIGHER or LOWER than 7.5 strikeouts?" and you choose one and pick a side.
- Split your pot however you like: Here's the twist: you don't have to go all-in on one side. You can split your pot between HIGHER and LOWER any way you want. For example, $600,000 on HIGHER and $400,000 on LOWER.
- Keep the winning side: Once the question settles, whatever amount you put on the winning side becomes your new pot going into the next question. Money on the losing side is gone.
- Repeat up to 20 questions: You'll keep answering new player pick questions, up to 20 in total. If your pot ever hits $0, the game ends.
- Keep what's left: Survive all 20 questions with money remaining, and you keep whatever's left in your pot.
Note: Payouts from Keep Your Million are paid out as bonus funds, not withdrawable cash.

What is Underdog, how does it work, and is it legal?
Underdog Sports, LLC operates the Underdog platform on iOS, Android, and web. Its core offering is contest-based fantasy play, where users pay an entry fee to compete against others in formats like Pick’em (higher/lower player stats) and draft-style contests with set scoring rules.From all the predictive market apps, Underdog offers a prediction-style product known as Prediction Picks, where users take positions on real-world outcomes using event contracts that fluctuate in price and settle based on the final result, with the option to exit positions early at market value."Underdog operates legally in the United States, but its availability and product offerings vary by state. Underdog’s fantasy contests and prediction-style games are structured to comply with applicable state laws, and the company adjusts which features are available based on local regulations."
Legal states & availability
Underdog availability is not a single, uniform map. It is determined by product line, and each product can be enabled or restricted state by state. In practice, a state may allow Fantasy while restricting Prediction Picks, or the reverse.| Product line | What it includes | How eligibility works |
|---|---|---|
| Fantasy | Pick’em (Classic), Pick’em Champions, Drafts, and other fantasy contest modes | Varies by state and sometimes by format. Some states are Drafts only, meaning Drafts may be available even when Pick’em is not. |
| Prediction Picks | Prediction market-style event contracts tied to game outcomes | Governed by a separate state map from Fantasy. Access depends on your physical location in an eligible state, plus applicable age and identity requirements. |
Fantasy eligibility (Pick’em vs Drafts)
Underdog’s state tool breaks down which fantasy formats are live in your state. The important detail is format-level access. “Drafts only” states exist, meaning you may be able to draft but not play Pick’em. Underdog’s published state chart also lists examples of states that may be ineligible for certain fantasy modes. The safest approach is to confirm your state in the tool before you fund your account.Prediction markets eligibility (Prediction Picks)
Prediction Picks runs under its own eligibility rules and its own state map. That means a state where fantasy contests are available can still restrict Prediction Picks. When it is available, access is based on your physical location in an eligible state, not just your account address, and it’s also subject to age and identity requirements.Promo eligibility is a third filter
Even if you’re eligible for fantasy in your state, a specific welcome bonus can still be excluded by state. For the 50% first deposit match offer, the published terms list it as not valid in FL, HI, IA, ID, LA, ME, MT, NY, or WA."Before depositing, confirm (1) your fantasy format eligibility (Pick’em vs Drafts), (2) whether Prediction Picks is enabled in your state if you want that product, and (3) whether the offer itself is valid where you are."

Underdog fees, limits & liquidity
Underdog does not operate as a traditional exchange, so costs and liquidity work differently than on other platforms. Instead of order books and bid/ask spreads, pricing and payouts are defined by contest rules or contract terms upfront.On Prediction Picks, you’re taking positions in event contracts with prices that can move before settlement. Where available, Underdog may let you exit a position early at the current market value, so always review the specific contract rules before confirming.Fees and pricing
Underdog does not charge explicit trading fees:- For fantasy contests and Pick’em entries, the platform’s edge is built into the payout structure, meaning the cost is reflected in the odds and prize pools rather than a separate fee line.
- For Prediction Picks, prices are set by Underdog and may include an implied margin, so it’s important to review potential payouts before confirming a position.
Limits and liquidity considerations
Because Underdog uses fixed-entry contests and platform-set prediction markets, liquidity is generally not an issue in the traditional sense. However, limits can apply. Entry caps, maximum stake sizes, and market availability vary by state and by product, and some prediction markets may close early or be unavailable in certain jurisdictions."As always, check Underdog’s official rules and state-specific terms before placing entries, especially when using bonuses or promotional credits."
Games you can play on Underdog
Underdog is built around two separate products. First, the fantasy side: Pick’em and draft contests that revolve around individual player stats.Second, Prediction Picks (Underdog Predict): a prediction-markets style product where you take positions in event contracts tied to game outcomes. Eligibility is handled per product and varies by state, so it’s common to have access to Drafts in a state where Pick’em or Prediction Picks is restricted.Below is an overview of the contest types you may encounter on Underdog:🏀 Pick’em (Classic)
Build an entry by choosing higher/lower outcomes on player stats. Your entry settles when the games finish.
🏆 Pick’em Champions
A distinct Pick’em mode treated separately from Classic in Underdog’s state-eligibility breakdown. It’s essentially its own category, so availability doesn’t always mirror Classic.
🎲 Draft games
Draft a roster and compete under a defined scoring system. Results settle based on game outcomes and the contest’s scoring rules.
📈 Streaks
A streak-based format where each correct result extends your run. The experience is built around progression over time rather than a single slate.
🏅 Team picks
A team-outcome focused format, designed around team results rather than individual player-stat selections.
⭐️ Event contracts (Prediction Picks)
Instead of paying an entry fee for a fantasy contest, you take positions in market-style contracts tied to real-world outcomes such as game winners or point spreads.
Underdog payment methods
Deposit options for Underdog
These are the primary methods US users can use to fund an Underdog account (minimum deposit $10). Availability and limits may vary by state, device, or your bank/issuer’s policies, and you must be located in a state where Underdog is legally offered.
Online banking (Trustly)
PayPal
Credit / Debit Card
Apple Pay
Venmo (where supported)
How withdrawals work
Deposits are usually the easy part. Withdrawals are where timing, minimums, and verification checks come into play. Underdog does not charge a withdrawal fee, and the standard minimum cash-out is $10. Processing typically takes 48 to 72 hours.The other key detail is promo credit. The 50% first deposit match bonus funds aren’t withdrawable on their own. Any winnings tied to bonus play become eligible for withdrawal only after the 1x playthrough requirement is met, and unused promo value can expire if you don’t use it within 14 days. Cash payouts are typically available through PayPal, Trustly, and Paysafe."Don’t let your first withdrawal be a surprise. Before you deposit anything meaningful, confirm your preferred cash-out method is available, complete verification, and check the minimum withdrawal so your balance doesn’t get stuck under the threshold."

Underdog promo code verdict and platform takeaways
Underdog is a strong all-around platform for US players who want fantasy contests first, with prediction-style markets as a secondary option. It excels at Pick’em and Draft formats, offers a clean mobile experience across iOS, Android, and web, and provides solid onboarding value through its new-user offer where available.Underdog works within the US by adjusting its offerings on a state-by-state basis, turning certain fantasy formats or prediction features on or off depending on local rules. That flexibility is a big plus, but it does mean you should double-check what’s available in your state before you deposit. Even if Prediction Picks face tighter restrictions in some places, Underdog’s core fantasy contests are still widely accessible, which helps the platform stay useful for more users.Overall rating: 3.9/5 ⭐️⭐️⭐️⭐️
