An offshore sportsbook is an online betting site based outside the U.S. that accepts wagers from American players without being licensed by U.S. regulators. These sites often promote bigger bonuses, looser wagering requirements, and broader betting markets but they operate outside state oversight.

Offshore sportsbooks are typically licensed in jurisdictions like Curaçao or Costa Rica rather than by U.S. state regulators. That means they’re not held to the same consumer protection standards you’ll see with legal apps like DraftKings or FanDuel.

Here’s how they differ from regulated sportsbooks:

  • No U.S. licensing: Not approved by state gaming boards
  • Fewer protections: Disputes, payouts, and fairness aren’t guaranteed
  • Payment risks: Withdrawals can be slower or more complicated
  • Access: Often available nationwide, even in states without legal betting

A common misunderstanding is that offshore sportsbooks are “legal everywhere” they’re usually unregulated, not officially legal, and using them can carry financial risk.
