Underdog Promo Code COVERS: Play $5, Get $100 2026

What is the latest Underdog promo code in October 2026?

Best Underdog promo code: Play $5, Get $100

The best Underdog promo code is COVERS, for the featured 'Play $5, Get $100 in Bonus Entries' Underdog welcome offer. Eligible users receive ten $10 bonus entries, distributed over 10 days.

For me, the appeal is straightforward: I don’t need to make a large first deposit to access the advertised $100 offer. This is a daily-entry promotion, not a $100 balance I can immediately put toward one selection, so it deserves a spot on our list of top prediction market promos.

How are the ten $10 bonus entries issued?

Here's a succinct breakdown for one of the best prediction market apps: The promotion distributes one $10 bonus entry per day for 10 days. That totals $100 in promotional entries over the full schedule.

Where do I find my Underdog bonus entries?

I start in the Underdog mobile app’s 'Promos' tab, the gift icon next to my balance. From there, I can find available bonus entries, select one, and apply it to an eligible entry. Promotional options can also appear while building an entry. Underdog’s help guide says you redeem bonus entries through the mobile app, not a web browser. 

Before confirming, I check that the $10 bonus entry is selected and review the displayed payout. Seeing a promotion in my account isn't the same as applying it.

How much is the Underdog deposit match worth

Underdog has a secondary deposit match offer, and the bonus calculation is straightforward:

Underdog secondary bonus = 50% of the first deposit, up to a maximum of $1,000

That means you need a $2,000 first deposit to get the full $1,000 bonus. Depositing more than $2,000 does not increase the match beyond $1,000.

This table is important because '1x playthrough' does not mean playing only the bonus once. The requirement applies to the deposit and bonus combined. A $500 deposit earns a $250 bonus, for a total of $750 in required qualifying entry volume. Official terms require that playthrough to be completed within 14 days.

Today's Underdog promo code check

The Underdog promo code COVERS unlocks the featured Play $5, Get $100 welcome offer, with one $10 bonus entry issued daily for 10 days. I’d confirm the promotion appears during registration before depositing, since Underdog offers can vary by campaign and eligibility.

My verdict on the Underdog welcome offer

I like the Play $5, Get $100 promotion because it offers substantial bonus value without requiring a large opening deposit. The catch is that the $100 arrives as ten daily bonus entries, rather than immediately available cash. I’d recommend it to newcomers comfortable with that format, while the separate 50% deposit match up to $1,000 may appeal more to users planning larger deposits.

How to claim the Underdog promo code COVERS

Here’s the process I’d follow for the Play $5, Get $100 offer:

My main check happens before I commit any money: the registration offer, promo code, and qualifying entry should all match the promotion I intend to claim.

Underdog Play $5, Get $100 terms and conditions

These are the main details I’d check before using the Underdog promo code COVERS: 

Does a bonus entry return its original stake?

Underdog’s bonus-entry guidance says a winning bonus entry pays the winnings without returning the promotional stake. The entry slip updates the displayed payout when you select the bonus.

For example, a $10 bonus entry with a standard 3x return before that adjustment would produce $20 rather than $30, because the $10 promotional stake is not returned. I check the final payout on the slip instead of treating a bonus entry as identical to $10 cash.

How long do I have to use the bonus entries?

I check the expiration attached to each entry in the app. Ten days describes the distribution schedule, not an automatic promise that every entry expires on the same day.

Underdog’s help center directs users to their account for the applicable bonus turnover period, so I check there before using an entry.

Does the Underdog promo code work on Prediction Picks?

COVERS is the Underdog registration code; whether a particular bonus entry can fund a Prediction Pick depends on that promotion’s eligible products. I check the options attached to the $10 entry rather than assuming it works on every contract in the app.

Underdog’s broader platform includes both Prediction Picks and fantasy Pick’em. Prediction Picks involve event contracts on outcomes such as game winners, spreads, totals, and player performances, while Pick’em follows its own entry and payout rules. The sports may be familiar across both products, but the mechanics are different.

Covers Expert Analysis

"Prediction Picks are still regulated event contracts with their own eligibility, trading, settlement, and withdrawal rules."

Christian Stringer, Prediction Markets Editor

What about Underdog Combo entries?

Combo entries combine Prediction Picks with fantasy selections. Underdog’s published rules require at least one Prediction Pick and two fantasy picks from different teams, with each part following its own product rules.

I like the flexibility, but I still check whether the specific daily bonus entry is eligible before building a Combo around it. A promotion applying to one entry format does not automatically establish that it applies to every other format.

How do I know which type of entry I’m making?

I check the entry slip rather than judging by the sport or player involved. In states offering both products, Underdog can select the entry type based on the combination of picks I make. Entries mixing fantasy and prediction selections are Combos. That is especially useful when I’m comparing a team’s chance of winning with a quarterback’s passing-yard projection. Both are football predictions in everyday language, but they may sit within different Underdog products.

Underdog $100 offer vs. $1,000 deposit match

The Play $5, Get $100 offer is the main promotion featured on this page. Underdog also has a separate 50% first-deposit match up to $1,000, subject to the offer presented and customer eligibility. I compare the structure, not just the largest number. One distributes a fixed amount in daily bonus entries; the other scales with the qualifying deposit.

How do I get the maximum $1,000 deposit-match bonus?

A $2,000 qualifying first deposit produces the maximum $1,000 match. Smaller deposits receive the same 50% rate: $100 earns $50, $200 earns $100, and $500 earns $250.

 The deposit-match terms are separate from the daily-entry promotion. They specify a $10 minimum deposit, crediting within 72 hours of deposit resolution, and 1x playthrough of the deposit plus bonus within 14 days.

For example, a $100 deposit plus a $50 match creates $150 in qualifying playthrough. That calculation belongs to the deposit match—not automatically to the Play $5, Get $100 offer.

Which Underdog welcome offer would I choose?

 I’d lean toward Play $5, Get $100 when I want a smaller starting commitment and am comfortable receiving promotional entries over 10 days.

The deposit match becomes more interesting when I already intend to fund the account with a larger amount. At a $200 deposit, a 50% match reaches the same $100 headline value; above that, the match produces a larger promotional amount. That does not make the offers equivalent, because distribution, eligible use, and playthrough differ.

I would not increase my deposit just to chase the larger headline.

Can I claim both welcome offers?

When Underdog presents promotions through Choose Your Offer, I must select one. Its published rules say the selection is final and does not entitle me to the other welcome offers shown alongside it.

I’d compare the available options before choosing rather than treating the $100 promotion and $1,000 match as a combined bonus.

Covers verdict on Underdog

Best for: Sports-first prediction trading

Underdog appeals to me because its prediction markets start with familiar sports questions rather than a screen full of trading jargon. I can assess a game winner, spread, total, or player outcome, review the contract price, and understand the potential return before taking a position. Eligible positions may also offer an early cash-out option.

The Play $5, Get $100 promotion gives the page a more approachable welcome-offer angle, but the daily format matters. I’m receiving ten $10 bonus entries, not an unrestricted $100 trading balance.

My approach is simple: understand the promotion first, then explore the product. That keeps the welcome bonus from overshadowing what matters once I’m using Underdog: prices, fees, entry rules, and the markets I actually follow.

Keep Your Million promotion

The Keep Your Million promotion starts eligible participants with a virtual balance of $1,000,000 in Milly Bucks and asks them to work through as many as 20 two-outcome player-pick questions.

Milly Bucks are not $1 million in cash, cannot be withdrawn, and are used only within the promotion.

Whatever remains after all 20 questions are completed converts into bonus entries, up to a maximum of $1 million. Those bonus entries must then be played through once before resulting winnings become eligible for withdrawal.

How Keep Your Million works

1. Start with $1,000,000 in Milly Bucks. Every eligible player begins with the same virtual pot.
2. Choose a two-outcome player question. One example could ask whether Tarik Skubal finishes Higher or Lower than 7.5 strikeouts.
3. Split the pot between both outcomes. I could put 650,000 Milly Bucks on Higher and 350,000 on Lower rather than going all-in.
4. Keep only the winning allocation. If Skubal finishes with eight strikeouts, my new balance is 650,000 Milly Bucks. The 350,000 placed on Lower disappears.
5. Continue for up to 20 questions. The current balance becomes the pot for the next round.
6. Finish with a balance remaining. Whatever remains after the 20th completed question converts into bonus entries. Reaching zero ends the promotion without a prize.

Complete all 20 questions within 60 days. Keep Your Million selections lock immediately and cannot be canceled after submission. 

A Keep Your Million example

Suppose I begin with 1,000,000 Milly Bucks:

• Question one: Tarik Skubal Higher or Lower than 7.5 strikeouts? I place 650,000 on Higher and 350,000 on Lower. Higher wins, leaving me with 650,000.
• Question two: Aaron Judge Higher or Lower than 1.5 total bases? I place 400,000 on Higher and 250,000 on Lower. Lower wins, leaving me with 250,000.
• Question three: A pitcher to record Higher or Lower than 5.5 strikeouts. I split 175,000 and 75,000. The 175,000 side wins, so that becomes my next pot.

The game is really a repeated risk-allocation puzzle. A wider split protects me from one outcome, but repeatedly preserving both sides can shrink the final balance quickly. 

Keep Your Million terms to know

Based on the current terms:

• Milly Bucks have no cash value.
• The promotion includes up to 20 sequential questions.
• You must complete all questions within 60 days.
• A zero balance ends the promotion without a prize.
• The remaining balance after 20 questions converts to bonus entries.
• The maximum possible conversion is $1,000,000 in bonus entries.
• Bonus entries have a 1x playthrough requirement.
• New users must make a first deposit.
• Existing users may have to make a separate qualifying deposit.
• The advertisement shown to the customer controls the qualifying deposit.
• Bonus funds are not directly withdrawable cash.

Underdog Rips promo: Get 5 free packs up to $750

Underdog has expanded beyond Prediction Picks with Underdog Rips, its sports card ripping experience. The product also lands on our list of the best card rip sites, giving me another way to use Underdog outside its prediction markets.

New Rips users can currently get five free rip packs worth up to $750, subject to eligibility and the promotion’s terms. Instead of trading an event contract, I open digital packs for a chance to pull sports cards, with the experience built directly around the excitement of traditional card breaks and pack openings.

I’d treat the Rips promotion separately from the Underdog promo code COVERS and its Prediction Picks offer. If sports cards are what I’m after, the free-pack promotion is the more relevant starting point.

What are Underdog Rips?

Underdog Rips turns opening sports card packs into a digital experience. I can choose an available pack, rip it to reveal the cards inside, and see what I pulled immediately. That makes it a very different product from Underdog Prediction Picks, but one that still fits naturally with the platform's sports-first approach.

For the full offer, available packs, and how Underdog compares with other platforms, check our guide to the best card rip sites.

What is Underdog Predict?

Underdog Predict is the event-contract side of the Underdog app. Instead of building a fantasy entry, I buy contracts tied to real-world outcomes such as a team winning, covering a spread, or finishing higher or lower than a total.

Each contract is priced between $0 and $1 based on the market’s estimated probability. A correct contract settles at $1, while an incorrect contract settles at $0. Prediction Picks are regulated financial instruments and are separate from Underdog’s fantasy Pick’em product.

In July 2026, Underdog launched its own federally licensed exchange after acquiring a CFTC-registered designated contract market and derivatives clearing organization. Underdog also operates as a registered futures commission merchant, giving it control of its own exchange infrastructure while continuing to offer contracts from partner exchanges.

Which exchanges power Underdog Prediction Picks?

Underdog currently works across three regulated exchange providers: 

Underdog generally shows one market per game and handles the exchange selection in the background. Users may hold positions from more than one provider at the same time, and each position settles under the rules of the exchange that listed it.

That is convenient, but it also means I cannot assume every Underdog market has identical fees, suspension rules, settlement rules, or availability.

How Underdog Prediction Picks work

Prediction Picks are built around contracts rather than traditional sportsbook odds. I choose an outcome, select how many contracts I want, review the contract price and fees, and submit the trade. The contract later settles at $1 if the outcome occurs or $0 if it does not.

Contract prices and payouts

A contract priced at $0.70 represents an estimated 70% probability.

Suppose I buy five “Bills to win” contracts at $0.70:

• Contract cost: 5 × $0.70 = $3.50
• Illustrative exchange fee: 5 × $0.02 = $0.10
• Total cost: $3.60
• Winning settlement: 5 × $1 = $5
• Net profit if correct: $1.40
• Settlement if incorrect: $0

That is Underdog’s own illustrative fee and payout example. The contract price matters as much as the outcome. Buying the correct side at $0.85 leaves only $0.15 of gross upside per contract, while buying it at $0.55 leaves $0.45 before fees.

Cash out and liquidity

Underdog may let me cash out a position before the event settles. The cash-out value is based on the current market price, so it may be higher or lower than my original cost.

I treat Cash Out as a sale, not an insurance button. Someone on the other side must be willing to take over the position. If there is not enough liquidity, the cash-out option can disappear even while my original contract remains active.

Cash out may also be suspended when:

• A market has insufficient liquidity.
• A significant in-game event causes trading to pause.
• The game is close to ending.
• I am physically located outside an eligible Prediction Picks state.

A position that cannot be cashed out continues to settle under its market rules.

Why I check the exchange before trading

The provider matters most when something unusual happens.

For example, a tennis retirement, postponed football game, or abandoned soccer match may resolve differently depending on whether the contract came from UDX, Kalshi, or Nadex. I would check the provider and rulebook before buying any contract where cancellation or retirement risk is realistic. 

Official exchange results, not the live score or stat display inside the app, control settlement. If there is a dispute, Underdog passes the exchange’s settlement through rather than independently changing the result.

Covers Expert Analysis

"I noticed Underdog's settlement help page was just updated. It clarifies that UDX, Kalshi, and Nadex each settle their own markets under their respective rules, while Underdog simply reflects that official exchange result. It also says most single-game markets settle within a few hours and payouts are typically processed within 24 hours of settlement."

Today’s Underdog Prediction Picks

🏈 Underdog NFL prediction markets

NFL Week 5 starts Thursday with Tampa Bay Buccaneers vs. Dallas Cowboys on Thursday Night Football. I’m watching that opener alongside Super Bowl, division, playoff, MVP, and weekly game markets before the rest of the slate, including Eagles vs. Jaguars in London, Ravens vs. Falcons, and Bills vs. Rams on Monday night.

🏟️ Underdog college football markets

Saturday brings several major college football matchups, led by No. 2 Georgia vs. No. 7 Alabama, No. 1 Texas vs. Oklahoma, No. 11 LSU vs. No. 24 Kentucky, and No. 9 Ole Miss vs. Vanderbilt. I’d compare available game and player markets as injury reports, lineup news, and prices develop throughout the week.

⚾ Underdog MLB markets

The MLB Division Series has four games today: Cleveland Guardians vs. Chicago White Sox, Los Angeles Dodgers vs. Atlanta Braves, Tampa Bay Rays vs. New York Yankees, and Milwaukee Brewers vs. San Diego Padres. I’d start with available game-winner contracts, then compare series, pennant, and World Series prices as the postseason field narrows.

Underdog Prediction Picks fees

Underdog fees can differ based on the entity and exchange handling the contract.

The published UDM fee schedule lists a $0.01 commission per contract, per side. In other words, buying 10 contracts creates a $0.10 commission when opening the position, and selling 10 contracts to close it can create another $0.10 commission. Separate exchange or regulatory fees may also apply.

Underdog’s Prediction Picks help center separately uses an example containing a $0.02 exchange fee per contract. Because Underdog routes markets through multiple providers, I would not reduce the entire fee section to a generic “two cents per contract” claim.

The order ticket is the source of truth. Before submitting, I would check:

• Contract price
• Number of contracts
• Underdog or UDM commission
•  Exchange fee
• Any applicable regulatory fee
• Total amount at risk
• Potential $1-per-contract settlement

The price on the market board is not always the final all-in price.

What markets can I trade on Underdog?

Underdog is primarily a sports-first prediction market, although some users can also access culture and current-event contracts.

Current sports categories include:

• NFL
• College football
• NBA prediction markets
• College basketball
• WNBA
• NHL
• MLB
• Soccer
• Tennis
• MMA
• Esports
• Championship and season futures

The exact selection depends on whether UDX, Kalshi, or Nadex powers the account and market.

Sports market types

Futures positions can remain open for weeks or months and may be eligible for early cash out when liquidity is sufficient. 

Underdog culture markets 

Some Nadex-powered accounts can access non-sports markets covering:

• Awards shows and entertainment
• Elections and government
• Economic decisions
• Business milestones
• Cryptocurrency prices

Underdog currently says culture markets are available for Nadex-powered accounts, with broader provider support expected later. The available questions change as events open and resolve.

Prediction Player Picks

Prediction Player Picks are available in Connecticut, Idaho, Iowa, Louisiana, Maine, and Washington. These can cover statistics such as passing yards, rushing yards, receiving yards, anytime touchdowns, and multiple touchdowns.

This is an important distinction from standard fantasy Pick’em. Prediction Player Picks are event contracts and follow the applicable exchange rules.

Prediction Parlays

Prediction Parlays let users combine multiple team contracts into one prediction entry. Not every market can be combined. A Prediction Parlay cannot be canceled after submission, although a cash-out option may appear based on the current market value and available liquidity.

Underdog payment methods and withdrawals

Underdog provides customers with a solid selection of deposit and withdrawal options. Payment methods include credit cards,like Visa and Mastercard, Apple Pay, PayPal, bank transfer, Trustly, and more. The minimum initial deposit is $10, and funding is instant and fee-free.

Underdog deposit methods

Underdog has several ways to fund an account, but I need to pay attention to which method I use if I plan on trading Prediction Picks. The minimum Underdog deposit is $10, and Underdog does not directly charge a fee for credit-card deposits.

Payment Method 🏦	Deposit 💰	Prediction Picks	Process Time 🕒	Minimum Deposit 🪙	Fee💲
Visa	✅	✅	Instant	$10	Free
Mastercard	✅	✅	Instant	$10	Free

Cash App	Limited/prepaid us	❌	Instant	$10	Free
Trustly	✅	✅	Instant; posting delays possible	$10	Free
Bank transfer	✅	❌	Instant	$10	Free

Underdog does not charge a direct deposit fee, although a bank or card issuer may. For Prediction Picks, I’d use an eligible debit or credit card, Apple Pay, or Trustly. PayPal and Venmo are available elsewhere on Underdog but currently can’t fund Prediction Picks.

---

Underdog withdrawal methods

Underdog withdrawals are free with a $10 minimum, unless I’m withdrawing an account balance below $10. Requests typically require 48–72 hours for Underdog to process before method-specific delivery time.

Withdrawal method 🏦	Available?	Underdog processing 🕒	Delivery after processing	Minimum Withdrawal 🪙	Fee💲
Visa	✅	48-72 hours	~24 hours	$10	Free
Mastercard	✅	48-72 hours	~24 hours	$10	Free

Credit card	❌	-	-	-	-
Apple Pay	❌	-	-	-	-
Prepaid/Cash App card	❌	-	-	-	-

Visa and Mastercard debit withdrawals require a previous deposit with that card, as do PayPal and Venmo. Trustly does not require a previous Trustly deposit.

How long do Underdog withdrawals take?

Underdog generally processes withdrawals within 48–72 hours. After approval, debit-card withdrawals typically arrive within about 24 hours, while Trustly can take another one to three business days. Weekends, holidays, or additional account reviews may extend those times.

Underdog customer support

Underdog offers customer support 24/7. Just click the live chat icon at the bottom of the page to quickly connect with a support agent. You can also send an email, but in my experience, it can take a few hours to get a response. 

The site does not have a large FAQ section. However, you can click the “Help?” button in the live chat to see a small list of common questions.

Where are Underdog Prediction Picks available?

Underdog Prediction Picks are currently available in 38 states plus Washington, D.C.

Eligible locations are:

Alabama, Alaska, Arkansas, California, Connecticut, Delaware, Florida, Georgia, Hawaii, Idaho, Illinois, Indiana, Iowa, Kansas, Louisiana, Maine, Minnesota, Missouri, Montana, Nebraska, New Hampshire, New Mexico, New York, North Carolina, North Dakota, Oklahoma, Oregon, Rhode Island, South Carolina, South Dakota, Texas, Utah, Vermont, Virginia, Washington, Washington, D.C., West Virginia, Wisconsin, and Wyoming.

Prediction-only states

The following states currently have Prediction Picks but do not have Underdog Pick’em or Drafts: Connecticut, Hawaii, Idaho, Iowa, Louisiana, Maine, Montana, Washington

Ineligible Prediction Picks states

Prediction Picks are not currently available in:

Arizona, Colorado, Kentucky, Maryland, Massachusetts, Michigan, Mississippi, Nevada, New Jersey, Ohio, Pennsylvania, and Tennessee. They are also unavailable in Ontario and U.S. territories.

Eligibility is based on physical location, not permanent residence. Users who travel into an ineligible state cannot place new trades or cash out until they return to an eligible location. 

Is Underdog legit and regulated?

Yes. Underdog Prediction Picks are event contracts traded through Commodity Futures Trading Commission (CFTC)- regulated exchanges. 

Underdog now owns and operates UDX, which includes a CFTC-registered designated contract market and derivatives clearing organization. UDM, LLC, doing business as Underdog Predict, is also a registered futures commission merchant regulated by the CFTC and NFA.

Underdog Predict and Underdog Fantasy are separate legal entities. Funds held in an eligible UDM futures account receive certain CFTC customer-fund protections, while fantasy-account funds do not receive those same futures-account protections.

Regulated does not mean risk-free. A losing contract settles at $0, and I can lose the full contract cost plus fees. Cash out is not guaranteed, and a thin market may leave me holding the position until settlement.

My Underdog Predict review

Who it's for

Underdog Predict is best for sports fans who want a simple, mobile-first prediction market experience without navigating a complicated trading interface. I like it for newer traders because contract prices are easy to understand, the market selection is heavily sports-focused, and existing Underdog users can access Predictions in the same familiar app. It’s particularly interesting in Connecticut, Hawaii, Idaho, Iowa, Louisiana, Maine, Montana, and Washington, where Prediction Picks are available even though other Underdog contests are not.

It’s less appealing if I want complete control over which exchange I use for a particular game or expect to cash out of every position early. Markets can come from different providers, meaning fees, rules, liquidity, and settlement procedures can vary, while cash-out availability ultimately depends on the market.

There’s no rigged competition, and every game makes it possible for anyone to win. Withdrawals do take a bit longer. However, they do all withdrawals manually, and you get to communicate with real people, so it's way more worth it."

How does Underdog price change tolerance work?

One Underdog Predictions feature I like is Price Change Tolerance, which gives me more control over how Prediction Picks are displayed and submitted. I can show prices as probability percentages or multipliers, while Price Change Tolerance lets me decide how much a contract can move against me before I need to reconfirm the trade.

The default tolerance is 5%, but I can set it anywhere from 0% to 20%, or choose to accept any price change. Underdog automatically accepts price improvements, so the setting only limits moves against me. I can adjust it directly from the Entry Slip or my Account Settings.

Price Change Tolerance applies to single Prediction entries and Pick'em + Prediction Combos, but not Prediction Parlays, which are submitted at the exact quoted price and contract count.

This is especially useful in fast-moving sports markets, where prices can change quickly after news, injuries, or game action. Setting a lower tolerance gives me tighter control over my entry price, while a higher tolerance can make it easier to get a trade through when the market is moving.

Underdog Predict at a glance

What I like about Underdog Predict

Sports-first market selection: Underdog has built the platform around the leagues and events sports fans already follow.

Simple contract pricing: A 63-cent contract represents roughly a 63% market probability. That is easy to understand after one example.

Multiple regulated providers: Underdog combines its own exchange with partner exchanges, expanding the range of possible contracts.

What I don't like about Underdog Predict

Provider differences create friction: Settlement, fees, and contract availability can vary between UDX, Kalshi, and Nadex.

Cash out depends on liquidity: The button can disappear when I need it most, especially late in a game.

Underdog app review

Underdog is a sports-first prediction market platform built around Prediction Picks, giving me a straightforward way to trade event contracts on game winners, spreads, totals, futures, player markets, and other sporting outcomes. The mobile experience keeps trading approachable, with simple contract pricing, quick navigation, position tracking, and cash-out functionality when available.

🍎 Underdog iOS app

The Underdog Sports app holds a strong 4.8/5 rating on the App Store, based on over 320K ratings. Click here to download the Underdog iOS app (197.3 MB size and growing). 

Underdog iOS app

🤖 Underdog Android app

Google Play Store users feel similarly about the Underdog mobile app, rating it 4.6/5. 

📱 Underdog app design 

Underdog's mobile interface is one of its biggest strengths for Prediction Picks. I can quickly browse available sports, select a market, review the contract price and potential payout, and submit my position without navigating a traditional exchange-style order book.

The clean bottom navigation also makes it easy to move between available Prediction Picks, open positions, settled trades, and my account. That simplicity is especially useful if I'm coming to prediction markets from sports betting rather than active financial trading.

📈 What I like about the Underdog mobile app

More Prediction Picks: Underdog offers sports event contracts covering markets such as game winners, spreads, totals, futures, and player outcomes, with availability varying by event and exchange.

Prediction Cash Out: Eligible positions can be sold before settlement at the available market value, letting me lock in a return or limit a loss when liquidity is available.

Streamlined trading: Underdog keeps the buying process simple, emphasizing contract prices, potential payouts, and fast mobile navigation rather than a complex trading terminal.

The Underdog mobile app was most recently updated to Version 26.64.0 in October 2026, introducing a chance to multiply your money by 5000x. Underdog has a well-earned spot on our list of the apps like Novig.
