My Experience With the Underdog Promo Code LABS

I used the Underdog promo code LABS first hand and my experience was great. I decided to sign up for the app to take advantage of this offer. After submitting my information required to sign up like my username and password, I was then prompted to link a payment account to deposit. I decided to link my bank account. After I linked my bank account with Underdog, I had a decision to make. How much do I want to deposit?

Underdog promo code LABS allows me to Play $10, Get $50! I deposited, entered a $10 contest, and the $50 landed once it settled. From there I used it across team and player outcomes and a few NFL best ball drafts.

I found that Underdog’s app and web interface is the most intuitive for everyone. It is a sleek design and offers a prediction market product without the confusing order books and limit orders. Want to trade on an outcome? I found that it was very easy to simply look at the percentage next to a team, tap the outcome, and trade the outcome.

This simplicity is not limited to team outcomes. Want to trade on player outcomes? That is also powered by the prediction market exchange. This allows a lot of access to a lot of users across the state. Anything I wanted to trade on I was able to find and place the trade with no hassle.

They also have the best drafting product available. They have a plethora of drafts available amongst a range of sports. I love best ball, specifically PGA Tour best ball and MLB playoff best ball. All of these were available and had an interface that is very easy to use.

How the “Play $10, Get $50!” Bonus Works

The $50 arrives after your qualifying entry settles, not when you deposit. So the sequence is deposit, enter, wait for the contest to finish, then collect.

What lands in the account varies by location. Some states get bonus funds, which sit in your balance; others get Bonus Entries, which cover the entry fee on a contest rather than adding spendable credit. The difference matters: with a Bonus Entry, a winning contest pays the profit in cash but the promotional entry fee itself isn’t returned.

Check the current promo code LABS tab to see which one you have before you build an entry around it.

Where to Use Your Underdog Bonus During NFL Week 8

NFL Week 8 opens Thursday with the Panthers at the Packers at 8:15 p.m. ET on Prime Video. Sunday’s games include the Ravens at the Bills, Sunday Night Football has the Eagles at the Commanders at 8:20 p.m. ET, and the Bears visit the Seahawks on Monday Night Football at 8:15 p.m. ET. The Texans, Saints, Giants and 49ers are on bye.

If I were starting with NFL player projections, I’d begin with Thursday’s single game and then move to Sunday for the wider selection of games and players. Carolina is averaging 4.3 yards per carry this season, compared with 2.9 for Green Bay’s offense, and Green Bay is 4-1 against the spread over its last five games, so rushing lines are one place to look. Injuries matter here too. Green Bay’s injury report lists receivers Jayden Reed and Skyy Moore and tight end Luke Musgrave as out, and Carolina is without receiver Xavier Legette, so check the final report before you submit.

On the other hand, the World Series is down to Game 5 October 28th with the Brewers leading the Rays 3-1, and the NBA Cup opens Friday with the Knicks at the 76ers. Games 6 and 7 follow Friday and Saturday if the series goes that far. Depending on what’s available in Underdog, those and college football give you other player pools to think about between NFL games.

If Pick’em or Champions is available where you are, I’d use PickLabs to narrow down the board, then check the live projections in Underdog before submitting. Available sports and game types vary by location, and the numbers can change before kickoff.

Underdog Game Types

What shows up in your Underdog lobby depends on your location.

• Underdog Predict: This product allows users to trade on the outcomes of sporting events, including player stat outcomes, the combined score, the point margin and which team wins. This is great for users who want to trade on games but are skeptical of technical platforms like Kalshi and Polymarket. This is my personal favorite out of Underdog’s products as it allows users to trade on both player and team outcomes with a design and UX that is not intimidating to someone without traditional prediction market experience.
• Underdog Drafts: This is one of Underdog’s legacy products. Underdog offers drafts to users in select states including but not limited to best ball, daily slates, and playoff best ball.
• Underdog Rips: Underdog has recently unleashed a new product called Underdog Rips, where users can purchase packs of sports cards in the app and keep them digitally, sell them instantly, or have them shipped to you. Odds, prices, and total value are listed before you open a pack so you know exactly what you are getting.

Where Is the Underdog Promo Code Available?

The LABS offer is currently listed in 40 states plus Washington, D.C.: Alabama, Alaska, Arizona, Arkansas, California, Colorado, Delaware, Florida, Georgia, Illinois, Indiana, Kansas, Kentucky, Maryland, Massachusetts, Michigan, Minnesota, Mississippi, Missouri, Nebraska, New Hampshire, New Jersey, New Mexico, North Carolina, North Dakota, Ohio, Oklahoma, Oregon, Pennsylvania, Rhode Island, South Carolina, South Dakota, Tennessee, Texas, Utah, Vermont, Virginia, West Virginia, Wisconsin and Wyoming.

Eight states have Underdog’s Predictions product only: Connecticut, Hawaii, Idaho, Iowa, Louisiana, Maine, Montana, and Washington. The fantasy welcome offer isn’t available in those states.

Underdog has no product in Nevada, New York is limited to Drafts and Rips.

Promo eligibility and game availability don’t always line up. Some states allow Drafts or Champions while limiting other formats, and Underdog checks your physical location every time you enter a paid contest.

Age minimums apply platform-wide, not just to this offer. Across eligible states, the floor is 18, with three exceptions: 19 in Alabama and Nebraska, 19 in Colorado for some games, and 21 in Arizona and Virginia.

Underdog Deposit and Withdrawal Options

Underdog accepts credit and debit cards, Apple Pay, Trustly, PayPal and Venmo for fantasy deposits. Google Pay is also being rolled out for Android users. The platform minimum deposit is $10.

Withdrawal options can include Visa or Mastercard debit cards, PayPal, Venmo, Trustly online banking and Apple Pay tied to an eligible Visa debit card. Debit card, PayPal, Venmo and Apple Pay withdrawals usually require you to have deposited with that method first. Trustly doesn’t require a previous Trustly deposit.

The minimum withdrawal is $10 unless your remaining account balance is below $10, in which case you can withdraw the balance that remains.

Underdog says withdrawal requests normally go through a 48-to-72-hour processing window. Depending on the method, your bank can add another one to three business days after that. Remember weekends, holidays and additional account checks can stretch the calendar, so a Friday request doesn’t always move at the same pace as one placed on a Tuesday.

Underdog App Review

Underdog keeps fantasy contests, drafts, Games and Prediction Picks in one app, so you don’t need to switch between different platforms. The products don’t all share the same balance, though. Prediction Picks placed through Underdog Predict use a separate futures account from your Underdog Fantasy funds, although you can transfer money between the two when authorized.

The entry builder adds player lines as you go and updates the potential payout before you submit, which makes it easier to compare lots of projections in the same stat category and see how each pick changes the entry.

Best Ball is a good fit if you enjoy drafting a team but don’t want to spend every Sunday adjusting your lineup.

The main learning curve comes from the fact that Pick’em, Champions, Drafts, Games and Prediction Picks all follow different rules. Check which product you’re using before submitting an entry, especially when you’re playing with promotional credit. Just because you have a Bonus in your account doesn’t mean it can be used on every option in the lobby.

The Underdog Sports app holds a 4.8 rating from about 323,000 ratings on the Apple App Store and a 4.6 rating from roughly 33,900 reviews on Google Play, checked October 2026.

My Experience With Underdog

A $20 Apple Pay deposit was usable instantly, with no hold before I could enter a contest, though I’ve had this account for years, so I can’t speak to first-time verification timing.

On August 27 I built a four-pick Standard card for $5 at 10x, all MLB strikeout props: Gerrit Cole over 5.5, Jacob Misiorowski over 8.5, Chris Sale over 6.5, Yoshinobu Yamamoto over 6.5. Sale and Yamamoto cleared comfortably at 11 and 8. Cole finished on 5, Misiorowski on 6. Two from four, which on a Standard entry pays exactly the same as zero from four.

That’s worth understanding before you reach for Flex. A four-pick Flex pays on 3-of-4, not 2-of-4, and building all four legs from one volatile stat is the shape most likely to land you at two, the one place Flex offers nothing.

Withdrawals have been the most reliable part. A $25 request submitted at 7am on August 19 landed roughly 36 hours later, inside Underdog’s stated 48-to-72-hour window, with no verification hold or payment review.

Is Underdog Legit?

Underdog launched in 2020 and has become one of the better-known fantasy sports platforms in the U.S. On July 30, 2026, London-listed IG Group agreed to acquire the company for up to roughly $1.3 billion, about $1.1 billion in upfront enterprise value plus an earnout tied to 2026 performance.

The deal is expected to close in late 2026 or early 2027, pending regulatory and antitrust approval, so Underdog continues operating independently, with its own brand and management team, in the meantime.

Underdog runs state-regulated fantasy contests. Since July 18, 2026, it has also run its own CFTC-licensed exchange for prediction markets, and it holds the DCM, DCO and FCM registrations needed to list and clear contracts in-house. Predictions made up 54% of Underdog’s handle in the first half of 2026, according to IG Group, and in early October Underdog CEO Jeremy Levine told IG shareholders that preliminary third-quarter handle was about $1.08 billion, up 199% from a year earlier.

What you can access depends on where you live, and each product comes with its own rules and disclosures.

Underdog Promos for Existing Users

Play $10, Get $50! is new users only, so an existing account doesn’t qualify.

What you do get is a rotating set of promotions that aren’t identical for everyone. Expect discounted projections, boosted payouts, protected entries and small bonus credits.

It’s always worth checking the Promotions tab before you build an entry, since that’s where active offers will show up. Each one will spell out the details clearly: what sport it applies to, the minimum entry size, when it expires, and how any bonus or return is paid out.

Some run for only a few hours or a single slate, so check the tab rather than assuming an offer you saw earlier is still live.

Finding Underdog Picks With PickLabs

PickLabs is built for Underdog players who’d rather not sort through every projection by hand. It surfaces value across player props and Pick’em contests for anyone working from projections rather than gut feel.

Filter projections by sport, compare player lines side by side, and assemble multi-pick entries from the strongest projected edges — rather than starting from a blank slip, you get options that already clear a value threshold.

The speed doesn’t remove the need to check your own work. Injuries, lineup updates, weather, and late scratches move the board in real time, so a play that looked strong in the morning can look very different by kickoff. Confirm the current line before you lock an entry.

Responsible Gaming at Underdog

Underdog includes several built-in responsible gaming tools to help users manage their play responsibly directly within the app and website. You can set deposit limits, entry limits, and time-based limits directly in your account settings, allowing you to control how much you spend and how often you play.

The platform also offers cool-off periods and self-exclusion options if you need to take a break from playing. These can be activated at any time and adjusted through your account, depending on the level of restriction you choose.

If entries are starting to feel like a problem for you or someone you know, help is available 24/7 through the National Problem Gambling Helpline at 1-800-GAMBLER, or 1-800-MY-RESET.
