Underdog Promo Code PCOM: Play $10, Get $50 in Bonus Entries - November 2026

The Underdog promo code PCOM gives you $50 in Bonus Entries when you place one eligible $10 entry. Alternatively, you can use the code to take a 50% deposit match worth up to $1,000, or five free Rips packs. I particularly like Underdog for its one-app mix of prediction markets and fantasy, its mixed combo entries and its own regulated exchange. Below, I explain how the three offers work and how Underdog differs from a pure prediction market.

How does the Underdog promo code work?

New players should enter the Underdog promo code PCOM when registering, then verify their ID and location. To unlock the play $10, get $50 offer, deposit $10 or more and place one eligible entry of $10. Underdog then gives you $50 in Bonus Entries that you can use on fantasy entries in the Underdog mobile app.

Bonus Entries can’t be used on standalone prediction picks, but can make up combos pairing one prediction with at least two fantasy picks. If one wins, you’re paid the winnings but not the stake, and those winnings are withdrawable. You then have 14 days from issue to play the bonus through once. Conditions can vary by state and product, so always check the latest rules in the app before depositing.

Choose from three Underdog promos

Play $10, Get $50 is one of three welcome offers the PCOM Underdog promo code unlocks. New users can instead take a 50% deposit match up to $1,000, which needs a $2,000 deposit to reach the full amount, or five free Rips packs. You can only choose one, and the choice is final. Note that the offers you see can depend on your state. The table below compares the three options.

How I used the Underdog bonus

I’d place my qualifying $10 entry on a two-pick Pick’em built around a single game, such as Jaguars vs. Ravens or Browns vs. Saints. You can choose higher or lower on player stat lines like passing yards or rushing yards, or pick a team to cover the spread or win outright. I’d avoid Drafts, which don’t count toward the offer, and I’d leave the entry alone once it’s placed, since Underdog only credits the $50 after its cancellation window closes.

Once the Bonus Entries land in the Promos tab of the app, I’d spread them across several smaller entries over the same few days. Quick-settling games make this easy, such as Ohio vs. Akron in midweek college football, or NBA games like 76ers vs. Pistons and Hawks vs. Wizards. Settling inside a day or two keeps you well within the 14-day window. Bonus Entries only pay winnings, not your stake back, so I’d size each entry with that in mind.

If you want prediction market exposure, I’d build a combo. Bonus Entries only work on prediction picks when they’re part of a combo, which needs one Prediction Pick plus two fantasy picks. For Jaguars vs. Ravens, that could be the Ravens to win, plus higher on the Ravens quarterback’s passing yards and lower on the Jaguars’ lead running back’s rushing yards.

Underdog promo code terms and conditions

The Underdog PCOM offer is for eligible new users. You need to place one eligible $10 entry, and the $50 in Bonus Entries must be played through within 14 days of being issued. The 50% match works to the same 14-day deadline.

  • Eligibility: New Underdog customers only, using promo code PCOM when registering. You can only choose one welcome offer. You must be 18+ (19+ in AL and NE; 21+ in AZ, MA and VA) and physically in a state where Underdog operates; the same applies to the 50% match and the Rips offer.
  • Qualifying play: One eligible entry of $10 or more, with a $10 minimum deposit (drafts don’t count); 50% match: a deposit of $10 or more; Rips: play $5.
  • Bonus: $50 in Bonus Entries; 50% match: 50% of your first deposit as Bonus Funds, up to $1,000 (a $2,000 deposit gets the full amount); Rips: five free packs with an advertised value of up to $750.
  • Playthrough: 1x the bonus, so $50 played through once; 50% match: 1x the deposit plus the bonus, so a $100 deposit with a $50 bonus means $150 in entry fees.
  • Time limit: Play the bonus through within 14 days of it being issued or it’s forfeited; the same 14 days applies to the 50% match; Rips: pulled cards must be kept, shipped or sold back within a few days.
  • Where it can be used: Fantasy entries only in the Underdog app, with prediction picks available only inside combos (one Prediction Pick plus at least two fantasy picks); 50% match: the same restrictions apply to Bonus Funds; Rips: used in Underdog Rips.
  • Withdrawals: Bonus Entries aren’t cash and can’t be withdrawn. If one wins you get the winnings but not the stake, and winnings are withdrawable; 50% match: Bonus Funds can’t be withdrawn until played through, though winnings can be withdrawn during the 14 days; Rips: cards can be kept in your vault, shipped or sold back at the displayed value.
  • Bonus timing: Usually credited within an hour after your qualifying entry’s cancellation window closes; 50% match: within 72 hours of your deposit.
  • Where can I claim the bonus: Underdog Predict is available in 46 states plus DC. This offer is built on fantasy entries, so availability varies by state, and the app shows which offers you can claim.

How do you claim the Underdog promo code?

Claiming the Underdog PCOM offer takes four main steps, including choosing your welcome offer from the three available. I recommend completing the process soon after registration, so you have plenty of time to place your qualifying entry and play the bonus through within 14 days.

  1. Sign up and verify

    Enter PCOM in the promo code field when opening an account on Underdog. Enter your name, date of birth, email and phone number. The app will ask you to verify your identity and location, which can include the last four digits of your Social Security number. You must be at least 18 (19+ in AL and NE; 21+ in AZ, MA and VA) and in an eligible state.

  2. Choose your offer and deposit

    Underdog gives new users a choice of three welcome offers: Play $10, Get $50; a 50% deposit match up to $1,000; or five free Rips packs. You can only pick one, and the choice is final. If you deposit without choosing, the options expire seven days later. In this example I selected Play $10, Get $50. The minimum deposit is $10. Payment methods vary by product, so check the cashier in the app.

  3. Place your qualifying entry

    Open Pick’em and build an entry of at least two picks, choosing higher or lower on each line. Set the entry amount to $10 or more. Once the entry’s cancellation window closes, Underdog credits $50 in Bonus Entries, which usually happens within about an hour.

    You’ll find your Bonus Entries in the Promos tab of the mobile app, as they can’t be redeemed in a browser. You then have 14 days to play the bonus through once, so you may find it easiest to start with quick-settling games, like a single NFL or NBA matchup. It’s also worth checking how cashing out early affects your playthrough before you commit.

  4. Use the bonus and withdraw

    Bonus Entries can be used on fantasy entries, and prediction picks are available only inside combos. The Bonus Entries themselves can’t be withdrawn. If a bonus entry wins, you receive the winnings but not the stake back, and those winnings are withdrawable. Withdrawal times and the minimum withdrawal depend on your payment method, so the app is the best place to check the details.

What is Underdog?

Underdog started in 2020 as a fantasy sports company, known for Pick’em, Best Ball and drafts. In 2025, the company moved into prediction markets under the name Underdog Predict, and now it has its own exchange.

Underdog Predict lets you buy and sell yes/no event contracts on real-world events and sports. Contracts cost from $0.01 to $0.99 and pay you $1 if you’re right or $0 if you’re wrong. A contract priced at 62¢ gives the market a 62% chance.

Underdog bought Aristotle Exchange, a CFTC-registered exchange and clearinghouse, in March 2026. In July 2026, it launched its own exchange, UDX, and now offers a request-for-quote system for bigger orders and a VIP program for large volumes. It also holds a futures commission merchant license, making it the first sports company with the full license stack. Some trades are still routed through Kalshi and Crypto.com.

Is Underdog legit?

Yes. Underdog Predict is supervised by the Commodity Futures Trading Commission (CFTC). It is an exchange (UDX) that is a registered market and clearing house. The business that operates it (UDM, LLC) is also a registered futures broker and is monitored by the National Futures Association.

Your Predict funds are separate from your fantasy money and receive special protection from the CFTC. The exchange also posts its rules and updates publicly.

Underdog is not licensed in every state like a sportsbook. Some states are challenging these contracts in court, so availability can change. For example in September 2026, Underdog pulled its fantasy product from seven states, so always check for availability.

Frank AmmiranteMy expert take

What I like most about Underdog is how easy it makes moving between fantasy sports and prediction markets. Being able to combine fantasy picks with event contracts without extra fees is a nice touch. I also like that it operates under CFTC oversight. The downside is that smaller markets can have limited trading activity, and I'd like to see more advanced trading tools. Still, I think it's a solid choice for sports fans, especially those already familiar with Underdog Fantasy.

Where is Underdog available?

Underdog Predict is regulated federally by the CFTC rather than licensed state by state like a sportsbook, so it’s available in most of the US, including California and Texas. Prediction Picks are live in 46 states plus Washington, D.C., with Arizona, Michigan, Nevada and New York the exceptions. Eligibility is based on where you’re physically located, rather than where you live.

Which games you can play varies by state. A handful of states, including Connecticut, Hawaii, Idaho, Iowa, Louisiana, Maine, Montana and Washington, have Prediction Picks but no Pick’em or Drafts. The Play $10, Get $50 offer needs a Pick’em entry, so the welcome offers you see depend on your state. You must be 18+ to trade on Underdog Predict, and some states set 19+ or 21+ for fantasy games.

Underdog promos for existing users

Underdog’s biggest ongoing promotion is Keep Your Million. It’s open to new players and some existing users, depending on the offer you’re shown. You start with a virtual $1 million balance, which has no cash value and can’t be withdrawn, and answer up to 20 Higher/Lower questions.

On each question, you split your balance between Higher and Lower, and only the amount on the correct side carries forward. If you put 60% on Higher and Higher wins, you keep 60% of your balance. If your balance reaches zero, the game ends with no prize.

Finish all 20 questions with a balance left, and it converts into bonus entries, up to $1 million, which you must play through once before any winnings become withdrawable. Start during the offer period and complete the game within 60 days. Details are on Underdog’s promotions page, and the Promotions tab in the app shows whether you qualify. Existing users may also see profit boosts, discounts and other account-specific offers there.

Underdog referral code vs the Underdog promo code

The Underdog promo code and referral code are separate offers. PCOM is a welcome offer for eligible new users, who can choose Play $10, Get $50 or one of two alternatives. A personal Underdog referral code lets existing users invite friends and potentially earn bonus entries if those friends complete required steps.

How to refer your friends to Underdog

Referrals work best with a friend who’s new to Underdog and ready to play, since your reward depends on them completing the steps below. The step that most often goes wrong is the friend not applying your code at sign-up.

  1. Open Account, then Invite friends

    Tap the Account tab in the top right of the app and scroll down to Invite friends. This is where Underdog shows your referral link and QR code, along with the current referral offer.

  2. Share your link or code

    Send your referral link or QR code to a friend. You can also give them your Underdog username, which works as your referral code.

  3. Have your friend sign up

    They need to create a new Underdog account using your link, which should fill in the code automatically. They can also enter your username under Add Promo Code during registration. Using a different promo code invalidates your referral bonus.

  4. Complete verification

    Your friend must verify their identity to play on Underdog.

  5. Meet the qualifying requirement

    Your friend then needs to make a deposit and play at least $10 in qualifying entries, paid with deposited funds. Draft entries or entries paid with bonus money don’t count. You also need to have made a deposit yourself.

  6. Receive your reward

    Underdog credits the bonus within 72 hours of your friend completing the requirements. Under the current offer, that’s a $10 bonus entry, with about 1 in 1,000 referrals winning a $2,000 jackpot that’s paid as 10 x $200 bonus entries. You then have 14 days to play it through once. Amounts can change, so check the Refer-a-Friend section of the app for current figures.

Tip: If your friend forgot to enter the code, they can contact Underdog support within 12 hours of creating their account and meeting the qualifying requirement to ask for it to be applied retroactively.

Underdog app review

Underdog overview

I like Underdog because it combines Predict, Pick’em and drafts in one app, which makes it a natural step for fantasy players who want to try prediction markets. Prediction Picks are easy to find, prices are in cents, and you can cash out from the Track section. You can also combine a Prediction Pick with fantasy picks in a combo, which you won’t find on pure prediction exchanges.

I’d recommend Underdog to sports fans and fantasy players who want simple trading. It may not suit serious traders: the markets are largely sports-focused, and order types and market depth are more limited than on larger exchanges. If you want politics or economics markets, Kalshi or Polymarket would be better fits.

What Underdog users say

Recent public app-store reporting gives Underdog Sports a strong overall score of about 4.8/5 on the App Store. Users note payouts and promotions and an easy-to-use trading platform as highlights.

“Compared to other apps, the interface and organization make it really easy to use and understand.”

App Store review

“Fixed payouts get old fast. Underdog does it better; the games, streaks and ladders give you way more freedom in how you play. Harder to win maybe, but way more fun. Great experience overall, would recommend to anyone.”

Underdog pros and cons

User experience on the Underdog app

Underdog feels more like a sports app than a trading screen, which I liked from the first time I opened it. You choose a sport, then a game, then the side you want. Before you confirm you see the price, your payout and the fee. You can find markets with the search bar and follow open positions under the Track tab, where you can cash out if there’s enough liquidity. Fantasy Pick’em and Predict sit in the same app, so you can switch between them without leaving it.

The iOS app is rated 4.8 and the Android app 4.7, both strong scores for a betting app. Underdog also runs in a browser, but I’d stick with the mobile app, which is built phone-first. Bonus Entries from the welcome offer can only be redeemed in the app anyway.

Underdog verifies your identity at sign-up and offers self-exclusion and cool-off tools and two-factor authentication. The trading screen is quick and simple, which suits casual traders, though experienced traders who want a full order book may find it limiting.

Markets and liquidity

Underdog is a sports-first platform. Here's what you can trade:

  • Football: NFL and college football, including game winners, spreads, totals and player props.
  • Basketball: NBA, college basketball and international leagues and WNBA in season.
  • Other sports: MLB, NHL, soccer, tennis, golf, UFC and boxing, motorsports and esports.
  • Culture: Awards shows, politics, economic data and cryptocurrency prices.

Underdog Predict is mainly sports-focused, so it’s not the best place for election or macro markets. If you care about politics, economics or weather, I’d check Kalshi or Polymarket alongside it.

Within sports, you can trade yes/no contracts on winners, spreads and totals, player props, build prediction parlays, or bundle a prediction pick with up to eight fantasy picks in one combo entry. Trading is open during most live games, and you can cash out from the Track tab if there’s enough liquidity behind the market.

Liquidity is best on the biggest games, where approved market makers post buy and sell prices. It’s weaker in college games and niche markets, and cash out can be suspended when trading is thin. UDX’s volume has grown quickly since its July launch, though it’s still smaller than Kalshi’s.

On price, quotes come from the exchange that lists each market, and on big games they usually sit close to Kalshi’s. Smaller games can differ by a few cents, and fees add to the total cost, so I suggest comparing Underdog’s quotes with our prediction market picks before taking larger trades.

Pricing and fees

Underdog doesn’t set the prices on Predict; traders on the exchange do. So if you buy a 62¢ Yes contract, you’re paying a price that reflects the market’s view of about a 62% chance. Underdog earns money from fees and doesn’t take the other side of your trade.

Combos don’t carry an extra fee, which compares well with sites that charge on every leg of a parlay.

Underdog’s fees depend on the exchange behind the market. Underdog charges a commission of $0.01 per contract on each side of a trade, and the exchange adds its own fee. On UDX, the taker fee is 0.07 × contracts × price × (1 − price), rounded to the nearest cent, so it peaks at 50¢. For example, 10 contracts at 50¢ carry an 18¢ exchange fee, and 10 contracts at 20¢ carry 11¢. Markets routed to Kalshi follow Kalshi’s fee schedule. Underdog doesn’t charge for deposits or withdrawals.

Use our market fee calculator to estimate the cost of the market fee before you trade.

Banking and payout speed

Underdog takes cards, Apple Pay and online banking. Deposits are instant in most cases. The minimum withdrawal is $10. Most withdrawals have to go back to a method you’ve already deposited with.

Customer support

Underdog has live chat in the app, which is the easiest way to get an answer from someone. You may be able to chat with an automated screener first before a human enters the conversation. You can also email them, but the response times are a little long. There’s no phone line.

Underdog vs. traditional sportsbooks

If you’ve played Underdog’s Pick’em, the app will feel familiar, but Predict works more like a stock exchange than a sportsbook. Instead of taking a set payout, you buy a contract at a price that moves with demand, and you can sell it before the game ends. Here’s how that differs from a traditional sportsbook.

Pricing

Traditional sportsbooks have fixed odds and a house edge built in, whereas Underdog Predict lets you trade against other users and prices shift to match supply and demand. Underdog charges exchange fees rather than taking a margin on the line.

Selling before the game

Your sportsbook bet is locked in unless the book offers a cash-out. If there is enough liquidity, you can sell your Underdog bets before the game. The value you receive depends upon the current price. It could be higher or lower than what you paid.

Regulation

The sportsbooks are licensed by state gaming regulators. Underdog’s contracts are regulated by the federal CFTC, which is why Underdog Predict is now available in states where sportsbooks aren’t, such as California and Texas. Note that some states are still disputing how sports contracts should be regulated.

What that means

To me, Underdog is like trading on top of a sports skin. Prices fluctuate while the game is being played, and I can choose to leave before the last whistle.

For a deeper look, check out our guide to prediction markets vs. sportsbooks.

Alternatives to Underdog

I would pick Underdog for fantasy players and anyone who wants prediction markets and Pick’em in one app, with combos you won’t find on a pure exchange. Even so, it’s sports-focused and has fewer markets than the biggest exchanges, so I recommend checking these alternatives before you commit.

Responsible trading on Underdog

Underdog uses an identity check at signup and offers features to help you manage your account. The company operates a responsible gaming program and a fund called GuardDog. It uses AI monitoring from Sportradar to spot risky play. Look under Responsible Gaming in the app for deposit limits and breaks. Underdog’s help center has the available options.

What I’d suggest to anyone just starting out is this:

  • Set a budget before you start, and never trade money you need.
  • Stick to sports and teams you know well.
  • Don’t chase losses with bigger trades.
  • Don’t deposit more than you can afford just to get a larger promotion. The 50% match only reaches $1,000 with a $2,000 deposit.
  • Don’t rush to meet a bonus deadline. The 14-day playthrough can tempt you into trading more than you planned.
  • Remember that favorites lose too. A contract bought at 90¢ pays $1 if it wins, a profit of just 10¢, but you lose the full 90¢ if it doesn’t.

What is the minimum deposit for the Underdog promo code?

The minimum deposit is $10 for the play $10, get $50 promotion. Deposit $10 or more, place one eligible entry of $10 or more, and Underdog credits $50 in Bonus Entries.

The 50% deposit match also has a $10 minimum. Underdog matches 50% of your first deposit up to $1,000, so a $10 deposit earns a $5 bonus. To get the full $1,000, you must deposit $2,000. The five free Rips packs offer is triggered by a $5 play. You can only choose one of the three offers, so pick the one that suits your first deposit.

Can I use the Underdog bonus on prediction markets?

Not on standalone Prediction Picks. Bonus Entries from the Play $10, Get $50 offer are for fantasy entries, but they can fund a combo that pairs one Prediction Pick with at least two fantasy picks.

Is Underdog a sportsbook?

No. Underdog Predict is a prediction market, where you trade yes/no event contracts at prices set by other traders, rather than against a sportsbook. It’s regulated federally by the CFTC rather than licensed state by state. Underdog’s fantasy products, such as Pick’em and drafts, are separate, and Pick’em uses fixed payout multipliers set by Underdog.

Is Underdog legit?

Yes. Underdog Predict runs through UDM, LLC, a CFTC-registered futures commission merchant, and Underdog owns UDX, a CFTC-registered exchange. Your prediction funds sit in a separate balance from your fantasy funds, and money moved back into the fantasy balance loses the protection that applies to prediction funds. Trading is risky, and you may lose your entire investment.

How do Underdog combos work?

You can build a prediction parlay from several team-based prediction contracts, or a combo that pairs a prediction pick with at least two fantasy picks from different teams, with up to eight fantasy picks. In a prediction parlay, every leg has to win, and a canceled or tied leg settles at its last traded price. Combos work differently: if your prediction pick loses but all your fantasy picks hit, you can still receive a partial payout, though Flex isn’t available.

How do I find my Underdog referral code?

Tap the Account tab in the top right of the app and scroll down to Invite friends. Your referral link and QR code are there, along with the current referral offer. Your Underdog username works as your referral code. Your friend should use your link, or enter your username under Add Promo Code at sign-up, because using a different promo code invalidates your referral.

How does arbitrage work on Underdog?

Arbitrage is buying opposite outcomes on two prediction platforms when the total cost is less than $1 and making a small profit. Underdog’s fees and cash-out limits reduce your margins, so make sure to check the total cost first. Our arbitrage scanner flags gaps across platforms.

What are the fees for Underdog?

Deposits and withdrawals are free. Each contract will incur a $0.01 commission per side, plus an exchange fee on the Kalshi and Crypto.com accounts and a price-based fee on UDX. Combos have no fee; the exact fee is displayed as you confirm your trade.
