PrizePicks vs Underdog: Which Fantasy App Wins in 2026?

The PrizePicks vs Underdog debate looks very different in late 2026 than it did a year ago. Both apps started as player prop pick’em platforms, and both still let you pick more or less on a stat line.

Since then, each company has changed owners or agreed to, added prediction markets, and reshaped what it offers state by state. Choosing between them now means weighing formats, regulation, and long-term direction, not just multipliers.

This comparison breaks down where the two apps overlap, where they split, and which one deserves your bankroll.

What is the Main Difference Between PrizePicks and Underdog?

The main difference between PrizePicks and Underdog is that PrizePicks focuses on a streamlined pick’em board and plugs into Kalshi’s exchange for its prediction contracts, while Underdog bundles pick’em, Rivals, Best Ball drafts, and its own federally regulated prediction exchange inside one app.

What is PrizePicks and What is Underdog?

What is PrizePicks?

PrizePicks is a fantasy sports and prediction app founded in 2015 and headquartered in Atlanta. It built its name on a simple player prop board where you pick more or less on individual stat lines.

Entries come in two main styles. A Power Play requires every pick to hit for the full payout, while a Flex Play still pays a reduced amount after a miss.

PrizePicks also lets you adjust risk on a single leg. Goblins offer easier lines at lower multipliers, and Demons offer tougher lines at boosted ones.

In 2025, PrizePicks moved its pick’em game to a peer-to-peer Arena format across much of the US. On most boards, you now compete against other users rather than the house.

The company’s ownership also changed. European lottery operator Allwyn closed its purchase of a 62.3% stake in January 2026, in a deal worth about $1.53 billion.

In November 2025, PrizePicks added prediction markets through a multi-year partnership with Kalshi. These appear in the app as Team Picks and Culture Picks, with a Polymarket integration announced for the future.

What is Underdog?

Underdog is a fantasy sports and prediction company founded in 2020 by Jeremy Levine and based in New York. Its daily pick’em game plays much like PrizePicks, but it places all of a player’s stat lines on a single card.

The app goes beyond daily props. It runs Rivals, a head-to-head format that pits two players’ stats against each other, and Best Ball drafts, one of the most popular season-long fantasy products in the industry.

Underdog entered prediction markets in September 2025 through a Crypto.com partnership. In March 2026, it acquired Aristotle Exchange, a CFTC-registered exchange and clearinghouse.

By July 2026, Underdog was running its own self-clearing exchange under the Underdog Predict name. That same month, it agreed to be acquired by London-based IG Group for $1.3 billion.

In September 2026, Underdog gave up its fantasy licenses in seven states so it could keep offering prediction markets there. Players in those states lost access to new Best Ball drafts but kept most of the rest of the app.

Key Differences Between PrizePicks and Underdog

1. Prediction Market Infrastructure: PrizePicks routes every prediction contract through Kalshi’s exchange via its own futures commission merchant subsidiary. Underdog owns its exchange outright after buying Aristotle Exchange, so it sets its own markets and fees.
2. Range of Game Formats: PrizePicks centers on Power and Flex pick’em entries, adjusted with Demons and Goblins. Underdog adds Rivals head-to-heads and Best Ball drafts alongside its pick’em game.
3. Board Layout: PrizePicks lists projections as individual cards across a broad board. Underdog groups every stat line for a player on one card, which makes multi-stat entries on the same athlete quicker to build.
4. Prediction Market Reach: Underdog Predict is live in roughly 35 states plus Washington, D.C. PrizePicks’ Team Picks and Culture Picks reach about 15 states so far.
5. Breadth of Prediction Markets: Underdog Predict covers more than 25 sports plus politics, weather, and economic events such as Fed rate decisions. PrizePicks currently offers a narrower lineup of game outcomes and cultural events sourced from Kalshi.
6. Ownership Path: PrizePicks is majority-owned by lottery giant Allwyn, which closed its deal in January 2026. Underdog agreed in July 2026 to join IG Group, a financial trading company, signaling a more markets-driven future.
7. State-Level Trade-Offs: Underdog surrendered its fantasy licenses in seven states to keep prediction markets there. PrizePicks has kept its fantasy product as the anchor and grown prediction markets more cautiously.

Key Similarities Between PrizePicks and Underdog

1. Core More-or-Less Gameplay: Both apps let you choose whether a player will go over or under a projected stat line. You combine several picks into one entry for a larger payout.
2. Fixed Multiplier Structure: Each app posts payout multipliers based on how many picks you make and which entry type you choose. The exact numbers differ in spots, but the logic is the same.
3. Federally Regulated Prediction Products: Both companies hold futures commission merchant status and offer CFTC-regulated event contracts. Either way, you are trading within federal oversight.
4. Single Account and Wallet: Fantasy entries and prediction trades live under one login on each platform. You do not need a separate app to move between products.
5. Wide Sports Coverage: Both boards cover the NFL, NBA, MLB, NHL, college sports, and a range of international and niche sports. Weekend slates on either app are deep enough for most players.
6. Mobile-First Design: Both platforms are built primarily for phones, with clean apps that let you build an entry in under a minute. Desktop access exists, but the apps carry the experience.

Features of PrizePicks vs Features of Underdog

1. Entry Types: PrizePicks offers Power Plays and Flex Plays in a peer-to-peer Arena format. Underdog offers standard and insured-style pick’em entries, plus a peer-to-peer Champions option in some restricted states.
2. Risk Adjusters: PrizePicks uses Demons for boosted lines and Goblins for safer ones. Underdog relies mainly on its standard multiplier table without an equivalent single-leg dial on most boards.
3. Additional Formats: PrizePicks keeps its focus on pick’em and prediction contracts. Underdog adds Rivals head-to-heads and Best Ball drafts where licensed.
4. Prediction Products: PrizePicks offers Team Picks for game outcomes and Culture Picks for entertainment events. Underdog Predict spans 25-plus sports and non-sports markets on its own exchange.
5. Exchange Backing: PrizePicks connects to Kalshi through its Performance Predictions II subsidiary. Underdog runs a self-clearing exchange built on its Aristotle Exchange purchase.
6. Board Design: PrizePicks displays a broad grid of individual projections. Underdog shows each player’s full stat menu on one card.
7. Banking: Both apps share one wallet across fantasy and prediction products. Underdog Predict accepts debit cards, Trustly, and Apple Pay.
8. Player Protection: PrizePicks pairs standard limits and self-exclusion with Kindbridge counseling access. Underdog provides app-wide responsible gaming tools and a shared help center.

PrizePicks vs Underdog Comparison Table

Final Verdict

Underdog is the winner of this matchup. It gives you more ways to play, from daily pick’em and Rivals to Best Ball drafts, all in one account.

Its prediction market product is also broader. Underdog Predict reaches more states and covers far more categories than PrizePicks’ Kalshi-sourced lineup.

PrizePicks remains a strong choice for beginners and for players who value simplicity and steady liquidity. It is also the safer pick in the seven states where Underdog dropped its drafts.

For most players who want depth, variety, and room to grow, though, Underdog delivers more value per login.

Pros of PrizePicks Over Underdog

1. Shorter Learning Curve: The board is easy to read, and every decision comes down to one line and one choice. New players can place a first entry within minutes.
2. Demons and Goblins Flexibility: You can trade probability for payout on a single leg without leaving the entry. Sharper players can use this to lean into lines they feel strongly about.
3. Access to Kalshi Liquidity: PrizePicks’ prediction contracts tap directly into Kalshi’s established order books. That typically means steadier prices and tighter spreads than a newer exchange can offer.
4. Stable Fantasy Footprint: PrizePicks has not given up fantasy licenses to chase prediction markets. Its core pick’em game remains available in the states where it already operated.
5. Polymarket Integration on the Way: PrizePicks has announced plans to add Polymarket’s markets once that exchange is fully live in the US. That should widen its contract menu over time.
6. Strong Responsible Gaming Tools: The app offers deposit limits, timeouts, and self-exclusion. It also partners with Kindbridge Behavioral Health for mental health support.
7. Well-Funded Parent Company: Allwyn’s backing gives PrizePicks deep financial resources. The company also carried no debt when the deal closed.

Cons of PrizePicks Compared to Underdog

1. Fewer Game Formats: PrizePicks has no direct answer to Underdog’s Best Ball drafts or Rivals head-to-heads. Players who want variety beyond pick’em will feel the gap.
2. Narrower Prediction Market Menu: Team Picks and Culture Picks cover fewer categories than Underdog Predict. You will not see the same depth of weather, economic, or political markets.
3. Smaller Prediction Market Footprint: Prediction products reach only about 15 states. Many PrizePicks users cannot access them yet.
4. Dependence on a Partner Exchange: PrizePicks inherits Kalshi’s fee structure and market list. It has less control over pricing and product design than an exchange owner.
5. Peer-to-Peer Shift Changed the Feel: The move to the Arena format means your results depend partly on how other users perform. Some long-time players miss the simpler house-backed structure.
6. Slower Multi-Stat Building: Because projections are spread across the board, stacking several stats on the same player takes more scrolling than on Underdog.

Pros of Underdog Over PrizePicks

1. All-in-One App: Pick’em, Rivals, Best Ball, and prediction markets sit under one login. You can play daily props and manage season-long drafts without switching apps.
2. Best-in-Class Best Ball: Underdog’s Best Ball tournaments are among the most popular in fantasy sports. They require no in-season management, which suits busy players.
3. Rivals Head-to-Head Format: Rivals lets you pick which of two players will post the better stat. It adds a fresh angle that PrizePicks does not center on.
4. Player-Card Layout: Every projection for a player appears on one card. Building correlated entries around a single athlete is fast and intuitive.
5. Own Regulated Exchange: Underdog holds the full license stack of exchange, clearinghouse, and futures commission merchant. It can launch markets and set fees without waiting on a partner.
6. Wider Prediction Market Coverage: Underdog Predict reaches about 35 states plus Washington, D.C. It covers more than 25 sports and several non-sports categories.
7. Strong Early Trading Volume: Underdog’s CEO has said the platform trailed only Kalshi and Robinhood in notional volume since its September 2025 launch. That is a strong showing for a young exchange.
8. More Picks per Entry: Underdog has historically allowed more picks in a single entry than PrizePicks. That opens the door to larger potential payouts for players willing to take on more risk.

Cons of Underdog Compared to PrizePicks

1. Best Ball Gone in Seven States: New drafts ended after September 9, 2026, in Massachusetts, Maryland, Michigan, Mississippi, New Jersey, Pennsylvania, and Ohio. Drafters there lost one of Underdog’s signature products.
2. Thinner Exchange Liquidity: Underdog’s exchange went live in July 2026 and is still building its order books. Prices can be less stable than on Kalshi-backed contracts.
3. Unclear Fee Schedule: Underdog sets its own trading fees but has not published a detailed public breakdown yet. Comparing costs is harder as a result.
4. Heavier Regulatory Exposure: Underdog’s aggressive prediction market push has drawn pushback from several states. Availability can shift quickly as regulators respond.
5. Pending Ownership Change: The IG Group acquisition could reshape priorities once it closes. Players who value continuity may prefer to wait and see.
6. No Single-Leg Risk Dial: Underdog lacks a direct equivalent to Demons and Goblins on most boards. You have fewer ways to tune risk on an individual pick.
7. More to Learn Up Front: With several formats in one app, newcomers face more menus and rules. Casual players may find the experience busier than PrizePicks.

Situations When PrizePicks is Better than Underdog

1. You Are New to Player Props: PrizePicks keeps the decision simple and the menus light. It is the easier place to learn how more-or-less entries work.
2. You Live in One of Underdog’s Seven Surrendered States: In Massachusetts, Maryland, Michigan, Mississippi, New Jersey, Pennsylvania, and Ohio, Underdog no longer offers new drafts. PrizePicks’ fantasy product remains the more complete option where available.
3. You Want to Fine-Tune Risk on One Pick: Demons and Goblins let you raise or lower the multiplier on a specific leg. That control is useful when you feel strongly about one line.
4. You Value Prediction Market Liquidity: Trading through Kalshi’s order books gives you more consistent pricing. Larger trades are less likely to move the market against you.
5. You Prefer a Long-Standing Fantasy Brand: PrizePicks has run its pick’em product since 2015 and kept fantasy at the center of its business. It is the steadier choice if you want minimal disruption.
6. You Only Play Daily Props: If Best Ball and head-to-heads do not interest you, Underdog’s extra formats add little. PrizePicks gives you a focused board without the clutter.

Situations When Underdog is Better than PrizePicks

1. You Love Best Ball Drafts: Outside the seven affected states, Underdog’s Best Ball tournaments are a major draw. Nothing on PrizePicks matches them.
2. You Build Entries Around One Player: The single-card layout makes stacking points, rebounds, and assists on one star quick and painless. Correlation-focused players save time.
3. You Want Head-to-Head Matchups: Rivals lets you compare two players directly. It suits fans who think in terms of who outplays whom rather than fixed lines.
4. You Trade Non-Sports Events: Underdog Predict covers politics, weather, and economic data. PrizePicks’ current prediction menu is far narrower.
5. Your State Lacks PrizePicks Prediction Markets: With about 35 states plus Washington, D.C., Underdog Predict reaches many players PrizePicks Predict does not.
6. You Want One App for Everything: Daily props, season-long drafts, and prediction contracts all share a single account. That keeps your bankroll and history in one place.
7. You Chase Larger Entries: Underdog has historically allowed more picks per entry. Players hunting for big multipliers have more room to build.

FAQs

Can I have accounts on both PrizePicks and Underdog at the same time?

Yes, nothing stops you from holding accounts on both apps, and many experienced players do exactly that. Having both lets you compare the line and multiplier on the same player before you commit. If PrizePicks posts a lower rushing yards line than Underdog, for example, taking the more side there gives you a better shot at the same payout. Just keep track of your total spending across both wallets so the habit of shopping lines does not turn into overspending.

Are winnings from PrizePicks and Underdog taxable?

Yes, winnings from fantasy contests and prediction contracts are generally treated as taxable income in the United States. Both companies issue tax forms when your net winnings for the year pass the IRS reporting threshold, but income below that level is still taxable. Prediction market profits may be treated differently from fantasy winnings, since event contracts fall under federal derivatives rules. Keep records of your deposits, entries, and withdrawals, and speak with a tax professional if your activity is significant.

What is the minimum age to play on each app?

The minimum age depends on your state and the product you use. Fantasy contests on both apps generally require you to be at least 18, but several states set the bar at 19 or 21. PrizePicks asks for 19 or 21 depending on location before you can trade its prediction contracts, while Underdog Predict requires users to be at least 18 where it operates. Both apps verify your identity and age during sign-up, so you cannot skip the check.

Is playing on PrizePicks or Underdog considered gambling?

The answer depends on which product you use and where you live. Pick’em contests are typically regulated as fantasy sports, which many states treat as games of skill rather than gambling. Prediction contracts are regulated federally by the CFTC as event contracts, which is why they can reach states without legal sportsbooks. Several states dispute that view, and the legal fight between state regulators and federal rules is still unfolding, so local availability can change.

What happens to my entry if a player does not play?

If a player is ruled out or never takes the field, both apps generally void that pick rather than count it as a loss. Your entry usually drops to a smaller number of picks with an adjusted payout, or it may be refunded if too few picks remain. The exact rule depends on the entry type and the app, and peer-to-peer formats can handle it differently from standard entries. Check the contest rules before game time, especially on slates with late injury news.

Will my existing Best Ball entries still count if I live in one of the seven affected states?

Yes, drafts you entered before the cutoff continue as normal through the end of their tournaments. The change only blocks new drafts in Massachusetts, Maryland, Michigan, Mississippi, New Jersey, Pennsylvania, and Ohio after September 9, 2026. You can still use most other parts of the Underdog app in those states, including prediction markets. Underdog’s founder has said the company has not ruled out bringing drafts back if the legal picture changes.

How fast are withdrawals on each platform?

Withdrawal speed depends on the payment method you choose and whether your identity is already verified. On Underdog, withdrawals go back through the same options used for deposits, such as a debit card, Trustly, or Apple Pay. PrizePicks pays prediction market winnings into the same wallet as fantasy winnings, so cashing out follows its standard process. Neither company publishes guaranteed timelines for every method, so complete verification early and check current processing times in the app before you request a payout.

Do PrizePicks and Underdog offer welcome bonuses?

Both apps regularly run sign-up promotions for their fantasy products, often in the form of deposit matches or bonus entries. These offers change frequently and may require a promo code at registration, so confirm the terms before you deposit. Neither platform has promoted a dedicated welcome bonus for its prediction markets, so any offer you see is likely tied to the fantasy side. Read the wagering requirements and expiry dates carefully, since bonus funds usually cannot be withdrawn right away.

PrizePicks vs Underdog Summary

PrizePicks and Underdog share the same more-or-less foundation, but they have grown in different directions. PrizePicks keeps things simple, leans on Kalshi for prediction contracts, and now has Allwyn’s resources behind it.

Underdog has built a broader platform with Rivals, Best Ball, and its own regulated exchange. That ambition brings wider reach in prediction markets, along with more regulatory risk and the loss of drafts in seven states.

Pick PrizePicks if you want a clean board and minimal fuss. Pick Underdog if you want the most formats and markets under one login.

Whichever app you choose, set limits, check your state’s current rules, and treat every entry as entertainment first.
