Where Underdog is not available
Third-party trackers (Lines.com, August 2026) report that Underdog's fantasy games are not offered at all in Connecticut, Hawaii, Idaho, Iowa, Louisiana, Maine, Montana, Nevada, and Washington. Its Predictions product can reach some of those states (for example Connecticut and Hawaii) because it is federally regulated. State lists change often; the app shows what is open where you are.
Is Underdog legit?
Yes. Underdog is a New York-based company founded in 2020, and its event contracts are offered by Aristotle Exchange DCM, Inc. and Aristotle Exchange DCO, Inc. ("Underdog Exchange"), which are subject to CFTC oversight. As Underdog itself states, trading involves risk, including total loss on positions. Fantasy contests and predictions are entertainment, not income.
