About Us

Best Offshore Sportsbooks compares offshore sportsbooks for US bettors — sites licensed outside the United States that accept players from states without their own regulated online betting market. We built this site because that gap in the US market leaves a lot of bettors searching for information that's honest about both the upside and the risk, and hard to find written in plain terms.

We are not a sportsbook. We don't take bets, hold funds, or process withdrawals. What we do is research offshore operators — their licensing, odds, market coverage, banking options, payout history and reputation — and put that research into rankings and reviews so readers can compare before they commit any money anywhere.

What We Actually Cover

Offshore sportsbooks sit outside the US regulatory system entirely. That single fact shapes everything we write:

• Every book we cover is licensed offshore — typically in jurisdictions like Curaçao, Panama or Costa Rica — and is not licensed or regulated by any US state.
• Accepting US players in this space is a legal grey area, not a settled legal status. We never describe an offshore book as "legal" in the way a state-regulated operator would be.
• None of the consumer protections that come with a regulated US book — segregated funds, state dispute resolution, guaranteed payout enforcement — apply here. If an offshore operator delays or refuses a payout, a reader has far fewer avenues to recover funds than they would with a licensed domestic book.
• Bettors are responsible for knowing their own state's laws before using any offshore site. We can't and don't give legal advice — anyone unsure of where they stand should consult a qualified professional.

We say this plainly because too much of what's written about offshore betting glosses over it. It's the single most important thing to understand before comparing bonuses or odds.

How We Score and Rank Sportsbooks

Every book on this site — including non-Gamstop UK casino coverage we produce for other markets — goes through the same set of checks before it earns a spot in our rankings:

• Licensing and track record — where the operator is licensed, how long it's been active, and its reputation for paying out on time.
• Odds and market coverage — pricing on spreads, moneylines and totals, plus depth of props, futures, live betting and parlay options across major and niche sports.
• Bonus terms — we look past the headline percentage to the rollover requirements, minimum odds, time limits and eligibility rules attached to any welcome or reload offer. A bonus without those terms attached isn't a complete offer, and we won't present it as one.
• Banking — deposit and withdrawal methods (including cryptocurrency such as Bitcoin, Ethereum, Litecoin and stablecoins like USDT or USDC), processing speed, payout limits and any fees.
• Verification requirements — how much KYC documentation a book asks for and when, since this varies significantly between offshore operators.
• Security and support — site security practices and how responsive customer support actually is when contacted.

Ranking position reflects this research, not payment. Commission from affiliate partnerships never buys a higher spot, and no operator can pay to improve its rating on this site.

Our Commercial Relationships

Best Offshore Sportsbooks earns revenue through affiliate partnerships with some of the sportsbooks listed here. If a reader clicks through and signs up, we may receive a commission. That relationship does not decide our rankings — a book with a strong affiliate arrangement gets the same scrutiny as one with none, and we'll say so when a site has a real limitation, including the ones ranked highest on this page.

What We Don't Do

We don't guarantee winnings, present betting as a source of income, or treat any tip or pick as a "lock." Betting carries a real risk of losing money, and with offshore operators there's an added layer of risk: the possibility that a book delays or refuses a payout, with none of the recourse a state-regulated dispute process would offer. Crypto payments carry their own volatility risk between the time funds are deposited and withdrawn. We try to be upfront about all of this rather than talk around it.

This site is intended for adults aged 21 and over. We do not create content aimed at, or intended to appeal to, anyone under that age, and nothing here should be read as encouragement to bet more than someone can comfortably afford to lose.

Responsible Gambling

Gambling should stay entertainment, not a way to chase losses or cope with stress. Offshore sportsbooks often have lighter responsible-gambling tools and self-exclusion options than regulated US operators, so it's worth checking what a site actually offers before relying on it. Anyone concerned about their own or someone else's betting can call the National Problem Gambling Helpline at 1-800-GAMBLER, or visit our Responsible Gambling page for more resources.
