This is the comparison people actually mean when they type "PrizePicks vs Underdog" — two pick’em DFS apps built on the same idea (over/under a posted player projection, not a moneyline) rather than a DFS-vs-sportsbook mismatch. Both call themselves fantasy sports. Both have spent the last few years getting tested by the same regulators, with different results.
PrizePicks vs Underdog, side by side
| PrizePicks | Underdog | |
|---|---|---|
| Founded | 2015, Atlanta (SidePrize LLC) | 2020, Brooklyn |
| Core product | Player Picks, Team Picks, Culture Picks — single pick’em lane | Classic Pick’em (DFS exemption) and Pick’em Champions (separately licensed peer-to-peer) |
| Sportsbook | Never had one | Ran one, closed it nationwide December 2025 after settling North Carolina wagers |
| Prediction market | None | Underdog Predict, CFTC-licensed, launched July 2026 |
| New York history | Left, then returned Feb 2026 on a new interactive fantasy sports license (Oct 2025) | Paid a $17.5 million NYSGC settlement in March 2025 over 2020–2022 contests, exited the state |
| State footprint | Paid Player Picks live in roughly 36 states plus D.C.; product-specific | Classic Pick’em under DFS exemption in roughly 15 states; blocked outright in CT, HI, ID, IA, LA, ME, MT, NV, WA |
| Age gates | 18+ most states; 19+ AL/CO; 21+ AZ/IL/MA | 18+ most states, higher where the state requires it |
Two Regulatory Pasts, One Product
Both apps run the same style of contest, so the real difference is what each company did when a regulator pushed back. PrizePicks left New York, waited, and came back in February 2026 with an actual license in hand. Underdog fought a narrower version of the same fight — the state said its 2020–2022 contests went past the temporary permit it inherited — and paid $17.5 million to close it out in March 2025, exiting the state as part of the deal. Neither story makes the other app illegitimate; they are just different outcomes to the same kind of scrutiny pick’em DFS has drawn nationally.
Is Underdog Legit If It Closed a Sportsbook?
Closing a product is not the same as failing at it. Underdog ran a licensed real-money sportsbook for a stretch and shut it down entirely in December 2025, settling every open North Carolina wager instead of chasing more state licenses. Reading that as a red flag misses what came next: Underdog used its own federal registrations — Designated Contract Market, Derivatives Clearing Organization, Futures Commission Merchant — to launch Underdog Predict in July 2026, a heavier regulatory lift than the sportsbook it walked away from. PrizePicks, by contrast, has stayed in one lane its entire history and has no sportsbook or prediction-market ambitions on the record.
Neither app is a sportsbook today. If an older article told you to "sign up for Underdog Sportsbook," that product is gone. Underdog Predict is a different, federally regulated product with its own state map — not a sportsbook rebrand, and not the same thing as pick’em Classic or Champions.
Which One for Who
Want the wider state list for straightforward player-projection pick’em, with a recent New York outcome that ended in a license rather than a fine: PrizePicks. Want Pick’em Champions specifically, or you are already curious about a CFTC-licensed prediction-market product and would rather have it under the same login as your DFS account: Underdog, with the caveat that Classic Pick’em’s own state list is shorter and nine states block Underdog outright as of 2026. Living in one of PrizePicks’ paid-Player-Picks states but not on Underdog’s Classic Pick’em list (or the reverse) is common — the two footprints do not match.
Neither company hands you a way to make money, and neither is a sportsbook substitute for a reader who actually wanted to bet a moneyline. If that is the goal, the DraftKings comparison on this site covers that different product entirely.
