Underdog Fantasy Review 2026: Best Ball, Pick'em & Draft Formats

Last Updated: March 2026

Underdog Fantasy is a multi-format DFS platform offering Best Ball drafts, pick’em props, and salary-cap contests across 30+ US states. Founded in 2020, Underdog has carved out a distinct position by combining zero-rake Best Ball tournaments with competitive pick’em payouts — though a 125-employee layoff in early 2026 signals a business in active restructuring.

How Does Underdog Fantasy Rate Across Key Categories?

Underdog scores highest on format variety and state availability, with its Best Ball product representing a genuinely differentiated offering in the DFS market. Our scoring reflects platform performance as of March 2026.

Format variety is Underdog’s strongest advantage. No other pick’em platform offers Best Ball drafts, which carry zero rake and represent some of the fairest DFS contests available. The business stability score reflects the early 2026 layoffs — factual context, not a prediction of future performance.

What Is Underdog Fantasy?

Underdog Fantasy is a daily fantasy sports platform founded in 2020 by Jeremy Levine and several former DraftKings employees. The company is privately held, with a valuation of approximately $500 million as of its most recent funding round. Investors include Mark Cuban, Kevin Durant, and BlackRock.

Business context (early 2026): Underdog laid off approximately 125 employees in early 2026, citing a need to restructure operations and focus on profitable product lines. The layoffs affected multiple departments and followed a broader DFS industry trend of cost-cutting after several years of aggressive user acquisition spending. Underdog remains operational across all its core products.

Underdog Sportsbook: Separately from its DFS platform, Underdog launched a licensed sportsbook in North Carolina. The sportsbook product operates under different regulations and is distinct from Underdog’s DFS offerings. NC sportsbook availability does not affect DFS state eligibility.

What Is Best Ball and Why Does It Matter?

Best Ball is Underdog’s signature DFS format and a key differentiator from PrizePicks and DraftKings Pick6, neither of which offer anything comparable.

How Best Ball works: Users draft a roster of players (typically 18 rounds for NFL) in a snake draft format. Over the season, the platform automatically selects your highest-scoring players each week — no lineup management required. At the season’s end, top-scoring teams across tournaments win prize pool payouts.

Zero rake: Underdog’s Best Ball tournaments carry no rake, meaning the full entry fee pool is returned as prizes. This is exceptionally rare in DFS. Underdog has stated it uses Best Ball as a customer acquisition tool, subsidized by revenue from pick’em and other products.

NFL Best Ball scale: Underdog’s NFL Best Ball tournaments are the largest in the industry, with individual tournaments exceeding $10 million in prize pools. The drafting experience — live snake drafts against other users — is well-executed and represents Underdog’s strongest product.

Best Ball is classified as traditional salary-cap DFS, which means it is available in more states (~44) than pick’em formats (~30).

How Do Underdog’s Pick’em and Champions Formats Work?

Pick’em: Users select 2-8 over/under predictions on player stat lines. Payouts are fixed multipliers based on the number of correct picks. Underdog offers both standard entries (all picks must hit) and Insured entries (one miss forgiven at reduced payout), paralleling PrizePicks’ Power Play and Flex Play.

Scorchers: Props where Underdog shifts the line in the player’s favor, marked with a fire icon. A standard line of 275.5 passing yards might become a Scorcher at 260.5 — same payout, easier target. Scorchers represent genuine value when the line shift meaningfully exceeds the player’s projection variance. Cross-referencing Scorcher lines against sharp market consensus on the Odds Reference dashboard can identify which Scorchers carry real edge.

Champions: A peer-to-peer format where users’ pick’em entries are matched head-to-head against other players. Instead of playing against fixed house payouts, you compete directly against another user’s picks. This P2P structure operates under a different regulatory framework than standard pick’em in some states.

Where Is Underdog Fantasy Available?

Underdog Fantasy operates across 30+ US states, but availability varies by contest type. Best Ball and salary-cap contests have the broadest reach under standard DFS regulations. Pick’em and Champions contests face the same regulatory restrictions that affect all pick’em DFS platforms.

Pick’em DFS restriction warning: Pick’em contests — including Underdog’s pick’em and Champions formats — are banned or restricted in: OH, MD, WV, WY, MI, NY, CO, PA, NJ, IA, CT, DE, MS, NC, and CA (AG opinion July 2025). Classic DFS formats like Best Ball are legal in approximately 44 states. Users must be 18+ in most states.

State availability changes as regulators update DFS classifications. Always verify current eligibility in the Underdog app before depositing. For a state-by-state breakdown of DFS legality, see our DFS legal states guide.

How Do Underdog’s Payouts Compare to Competitors?

Underdog’s 3-pick standard payout (6x) exceeds PrizePicks’ 3-pick Power Play (5x) — the most notable multiplier gap between the two platforms. At 2-pick and 4-pick tiers, the platforms are equivalent (3x and 10x respectively).

Multiplier comparisons alone are insufficient for evaluating platform value. A higher multiplier on a tighter line produces no additional edge. What matters is whether you can identify props where your projected accuracy exceeds the implied break-even rate — and that requires comparing each platform’s lines against sharp market consensus. Our expected value calculator can help quantify the math.

What Is the Underdog Fantasy Affiliate Program?

Underdog operates an in-house affiliate program through Underdog Partners. The program is managed internally rather than through a third-party affiliate network.

Program details:

• In-house management through Underdog Partners
• Third-party networks also carry Underdog offers at reported rates of $4.50-$6.05 per install
• Direct partnerships may offer different terms than network rates
• Attribution via unique referral links with reporting dashboard

Publishers with DFS-focused traffic should compare direct Underdog Partners terms against third-party network rates, as the economics can differ. For context on DFS platform economics, see our DFS vs. pick’em guide.

Is There an Underdog Fantasy Welcome Bonus?

[UPDATE: Underdog Fantasy offers a welcome bonus for new users. The specific deposit match amount, playthrough requirements, and expiration timeline change periodically. Check the Underdog Fantasy app or website for the current promotion available in your state.]

As with all DFS bonuses, read the full terms before depositing. Pay attention to which contest types count toward playthrough and whether bonus funds expire on a fixed timeline.

Key Takeaways

• Underdog Fantasy’s Best Ball format — with zero rake — is the fairest DFS contest type available and a genuine differentiator that no pick’em-only platform replicates.
• Pick’em payouts are competitive with PrizePicks, with a notable edge at the 3-pick tier (6x vs. 5x). Scorchers provide occasional line-value opportunities.
• The early 2026 layoff of 125 employees reflects industry-wide restructuring. Underdog remains fully operational across all product lines.
• Pick’em DFS is restricted in 14+ states. Best Ball and salary-cap DFS are available more broadly (~38-44 states).
