Offshore sportsbooks have become an important choice for bettors living in the USA, especially in states without legal sports betting, offering a way to wager on tennis and all the other major sports. However there are also other benefits at the offshore bookmakers. These betting sites usually provide very competitive odds and even unique markets for tennis fans (as well as basically all other sports you can imagine). But what is an offshore betting site? Why should I consider it, and is it safe to use?
What Are Offshore Sportsbooks?
Offshore sportsbooks are online betting platforms based outside the U.S., typically in countries like Panama, Curaçao or Costa Rica, where they’re licensed to operate. Unlike regulated sportsbooks, which follow state-specific U.S. laws (for example in New York or Nevada), offshore sites accept USA players regardless of state regulations (also filling gaps in the 11 states without legal betting currently). They use secure websites and one of the major differences is that they often support cryptocurrency betting like Bitcoin and USDC alongside traditional payments, offering bets on sports, esports, casino games and more.
Advantages Over Regulated Betting Sites
Offshore betting sites offer several benefits compared to U.S.-regulated platforms (like DraftKings).
- Wider Betting Markets: Offshore sites cover niche sports (ITF tennis, table tennis) unique bets (player aces in a tennis match) and also more parlay and live betting options, compared to the regulated bookies.
- Competitive Odds: Less regulatory overhead allows better odds, and bigger payouts. For example, we often find that Bovada’s tennis odds are higher than the odds over at state-regulated sites.
- Generous Bonuses: Offshore platforms always provide larger welcome bonuses and even more important, ongoing promotions and reload bonuses.
- Accessibility: Available in states without legal betting, offshore sites works well for bettors in restricted areas like Utah or Florida. But also, in general for USA citizens, it’s a much faster and easier process to register and deposit at the offshore betting sites.
- Flexible Payments: They support cryptocurrencies, e-wallets and credit cards, with generally faster payouts with less hassle.
Important note though, offshore sportsbooks operate in a legal grey area, as they’re not licensed by U.S. states, and it’s recommended to verify platform reputation to avoid risks. All the US betting sites added on this page have been operating for many years (often more than 20 years), have many thousands of active bettors and is considered safe by basically all users.
We have tried many of the USA offshore sportsbooks, especially for betting on tennis, and we think you will have a good experience at the below listed sites.

All above options arere licensed offshore, ensuring operational security, but you as a bettor should always check local laws, as offshore betting isn’t state-regulated.
