Offshore Sportsbook Index is written by one person. Every entry on the ranking was compiled by Marcus Feld, who has covered offshore and international operators since 2017. There is no review panel and no anonymous contributor pool, because a byline nobody can check is not a credential.
Most comparisons of offshore sportsbooks rank on bonus size. That is the least useful axis available, because the largest headline on this page carries the heaviest rollover attached to it. The rollover spread across these fifteen books runs from 8x to 30x, which means the order by headline and the order by what a bettor can actually clear are close to inverted. So the rollover sits on the row, beside the offer, rather than in a footnote.
Each state list is read out of that operator's own published affiliate and account terms. Not from another comparison site, and not inferred from which states have licensed markets. Where a source was ambiguous the state was listed as restricted rather than omitted: a wrong entry in that direction costs a reader one wasted click, and in the other direction costs them a closed account with a balance in it.
No star ratings, no house trust score, no odds-quality index and no hold percentage for any operator. Scoring an offshore book's pricing properly would take sustained line-tracking this publication does not do, and repeating an operator's own marketing as a finding would lend it a credibility it has not earned. This page would rather be thin than misleading.
More than thirty US states license online sportsbooks of their own. Everything rated here is licensed outside the United States and falls outside every American regulator's reach, which is disclosed on each page rather than buried under a licence badge.
Offshore Sportsbook Index earns a commission when a reader opens an account through a link here. It does not affect what is published about any operator: the rollover figures are facts, and the book with the largest headline offer in this lineup also carries its heaviest rollover.
Marcus Feld has covered offshore and international gambling operators since 2017, and has spent most of that time on the unglamorous half of the subject: rollover arithmetic, cashier behaviour and the gap between what an operator advertises and what its terms say.
