Our verdict
Updated 19 Sept 20261win is run by 1Win N.V., which holds a Curaçao (CGA) licence whose term ended on 6 March 2026; the regulator's register lists the renewal as 'Assessment in progress'. It is the most active of the brands we added in September 2026 by on-chain activity. A November 2024 data breach exposed records of about 96 million users.
Who runs 1win
1win has operated since around 2016 and trades under many mirror domains; this page covers 1win.com. The Curaçao licensee that matches the brand is 1Win N.V. (registration 147039). We could not read a live footer: 1win.com loads its legal text from an API, and our checking network received a partial-block response.
1win licence check
We checked on 19 September 2026 against the Curaçao Gaming Authority register dated 16 September 2026. Licence OGL/2024/587/0621 (1Win N.V.) was issued on 6 September 2025 with a term ending on 6 March 2026, and the renewal is shown as 'Assessment in progress'. 1Win N.V. does not appear in the CGA enforcement register.
Because the footer was not visible, the link between 1win.com and this licence rests on the company name alone. A separate Anjouan licence covers 1winbets.pro under a different company; we found no link to the brand.
How popular is 1win?
1win has an organic row on DappRadar's gambling leaderboard, where it ranks among the more active crypto casinos. Its reach is larger than the 1win.com domain suggests, because traffic is spread across mirrors.
