Four products, four rulebooks

  • Kalshi is a federally regulated event-contract exchange overseen by the CFTC. It is not a sportsbook; you trade yes or no contracts on outcomes.
  • Novig uses a sweepstakes, dual-currency model with a peer-to-peer twist, run under sweepstakes rules rather than a state gaming license.
  • Underdog Fantasy is daily fantasy sports, regulated as DFS, which is legal in more states than traditional sportsbooks.
  • Hard Rock Bet is a state-licensed sportsbook and casino, live only where it holds a license.

Why is it legal here is complicated in 2026

Because each model is governed differently, availability is decided state by state, and some of it is being fought over in court right now. Prediction-market sports contracts in particular have drawn legal challenges in several states during 2026, so an app that works in one state may be blocked or contested in the next, and the situation can change month to month.

How to check before you deposit

Never assume. Every one of these apps publishes a state-availability or eligibility page, and each enforces your location with geolocation and your age at sign-up (18+ for most, 21+ for sportsbooks and some others). Check the app's own current state list, confirm your age eligibility, and remember that being able to create an account is not the same as being able to play or redeem where you live.

Treat it as entertainment, not income

All four carry real risk of loss, and none should be treated as a way to make money. Set a budget you are comfortable losing, never chase losses, and if it stops feeling like entertainment, step away. Help is available any time in the U.S. at 1-800-GAMBLER.
