Underdog Fantasy

Overview

Underdog Fantasy launched in 2020 and has grown into one of the largest daily fantasy operators in the United States, best known for Pick'em higher/lower contests, Best Ball Mania tournaments, and real-time drafts. The company reports availability in 40 states plus Washington, D.C. for its Drafts product, with Pick'em contests live in 34 of those states. College Pick'em is off in eight of those markets — Alaska, Arizona, Indiana, Massachusetts, New Hampshire, New York, Tennessee, and Vermont — because of specific state DFS rules. Florida is a particularly instructive case: after the Florida Gaming Control Commission sent cease-and-desist letters to Underdog, PrizePicks, and Betr in 2023, Underdog eventually re-entered the state with a peer-to-peer Pick'em format that skirts the against-the-house structure regulators took issue with.

Welcome Offer

New users who deposit at least $10 and submit a first paid entry of $5 or more can receive up to $50 in Fantasy Bonus Entries through Underdog's standard new-user promotion (promo code text varies by affiliate). Underdog's help center notes that deposit match boosts — typically 20% to 50% — are run around tentpole events like March Madness and the NBA Playoffs rather than as a permanent first-deposit match. Bonus entries carry a 14-day clock; anything unused is clawed back. That is meaningfully less generous than a traditional 100% match, and it is not cash: bonus entries must be used inside contests, and winnings from those contests are what become withdrawable.

Product Depth

Underdog's core differentiator is product variety. Pick'em lets users chain two to five higher/lower player projections — think LeBron points, Mahomes passing yards — into a single entry. Underdog also runs Rivals (head-to-head player comparisons) and Champions (tournament-style pick'em with big-field payouts). The Drafts product includes snake drafts for NFL Best Ball Mania, one of the largest guaranteed-prize-pool tournaments in DFS, along with slow drafts and in-season weekly formats for NBA, MLB, and college football. Season-long Best Ball is the flagship for serious players, and Underdog continues to publish public player projections and ownership data that make it friendlier to research than some peers.

Pricing

Entries start at $0.25 for Pick'em and scale to thousands of dollars for Best Ball tournaments. There are no subscription fees. Underdog's rake on Pick'em is baked into the payout tables — winning a 5-pick all-correct ticket pays 20x, which is lower than the ~32-to-1 true odds on five independent coin flips (32x), implying a hold in the high teens on the headline product. Best Ball Mania entry fees run from $10 to $250 depending on the tier.

Banking

Deposit options include debit cards, PayPal, Venmo, ACH bank transfer, and Apple Pay. Withdrawals are processed to the original funding source where possible. PayPal and instant debit withdrawals are typically same-day; ACH can take three to five business days. Underdog does not charge deposit or withdrawal fees on standard methods, though the processor occasionally rejects prepaid and gift cards.

User Experience

The mobile app is widely considered the best in the DFS category. Pick'em entry-building is fast, the live scorecard updates cleanly, and historical player stat lines appear inline next to projections. The slow-draft room UX is genuinely enjoyable — it is one of the few DFS products that draft-heads log into for entertainment as much as for the money. Customer support runs through in-app chat and email; response times run a few hours during the day and longer on weekends. The one persistent gripe from power users is that projection edits sometimes lag breaking news by a few minutes, which creates short windows where sharp players lock in stale lines.

The Bottom Line

Underdog is the most polished DFS operator in the U.S. market, with a product slate that goes well beyond pick'em into drafts that real fantasy players want to enter. Where it loses points is on state availability and headline promo value: Pick'em is not legal everywhere, the welcome offer is modest compared to a 100% match at a peer like PrizePicks, and the effective hold on pick'em payout tables is meaningful. For Best Ball, drafts, and tournament depth, it is the category leader. For pure pick'em value, shop the payout tables carefully against other operators before committing.
