Underdog Fantasy Review 2026
Underdog is the pick’em app we open first, from NFL Sundays to CS2 majors. Here is what it does well, where it falls short and the hit rate each entry needs.
Underdog posts player numbers on the NFL, NBA, college football, MLB, NHL, soccer, golf and CS2, and its board runs deeper than any other pick’em app we use. Standard entries pay 3x on two picks up to 20x on five, and Flex entries can survive a miss.
The cost is the hit rate: every entry size needs each pick to land about 55% of the time to break even. Pick’em is live in about 32 states plus DC. In September 2026 Underdog gave up its fantasy licenses in seven states to keep its own prediction market, Underdog Predict.

Good and not so good
Good
- Deepest player board of any pick’em app we track
- Every sport we cover, from the NFL to CS2
- App holds up during a live slate
- Flex Play gives a floor when one pick is a stretch
Not so good
- CS2 numbers do not always adjust for how many maps a series goes
- Every entry needs about 55% per pick to break even
- Pick’em left seven states in September 2026
- No exit once an entry is in
How it works
Underdog posts a number for each player stat. You pick higher or lower on two to six players, and the payout grows with each pick you add.
A player in a series that goes the full distance plays about a third more maps than one who gets swept. Posted kill numbers do not always reflect that, so weigh how close the series looks before you pick.
The hit rate you need
What each entry size asks of every pick to break even over time.
| Entry | Payout | Break-even per pick |
|---|---|---|
| 2 picks | 3x | 57.7% |
| 3 picks | 6x | 55.0% |
| 4 picks | 10x | 56.2% |
| 5 picks | 20x | 54.9% |
This is the hit rate on each pick, not on whole entries. A 2-pick entry feels safe but asks the most.
Getting started
Verification takes a few minutes. Check your state on Underdog’s site before depositing.
Choose your reads, then count them. Do not start from a payout and work backwards.
Match the entry size to the break-even rate. If a pick cannot clear about 55% on its own, leave it out.
