Services and operations
1win runs online sports betting and casino gaming, including bookmaker services processed through its website and associated online payment.[1][2][3] It operates in multiple countries across the world, with activities and ties to Russia,[3] Ukraine,[4][5] Belarus, Nigeria, Mexico,[6] and South Africa, among others.
In Kazakhstan, access to the 1win platform is blocked and authorities are investigating its operations.[7][8][9]
In Russia, the service is blocked as an unlicensed bookmaker and functions via mirror domains.[3]
Criminal investigation
In 2023, Kazakhstan authorities opened an investigation into the online casino and bookmaker services provided through the 1win platform, stating that the site accepted payments through internet acquiring without user authentication, and that minors could take part.[1] The site was blocked in the country, and the organizers were placed on an international wanted list as part of the case.[1][2][10]
Kazakhstan's Agency for Financial Monitoring reported that four suspected organizers were placed on an international wanted list, and a pre-trial seizure was imposed against their personal vehicles and financial assets in 2024. Criminal income was estimated at ₸3.8 billion.[11][12]
After the start of the investigation in Kazakhstan, the platform's activity drew attention in Ukraine, where it was operating without a license.[4][5]
Data breach
In November 2024, the 1win platform suffered a data breach in which attackers copied data for roughly 96-100 million users, including email addresses, telephone numbers, IP addresses, countries, geolocation, dates of birth and passwords hashed with SHA-256. The dataset was later added to the Have I Been Pwned? database.[13][14][15]
Following extortion demands that escalated to US$15 million during negotiations, portions of the stolen databases were posted on underground forums in early November 2024.[15][16]
Esports and initiatives
Charity projects
1win funds community and charity projects in Africa, Asia, and Latin America.[17][18] A lighting project in Dharavi provided electricity to about 1,000 households.[19][20] In 2024–2025, 1win Charity ran free health-screening camps in Nigeria[21] and provided holiday support for cancer patients at Korle-Bu Teaching Hospital in Accra, Ghana.[22][23] Environmental and inclusion initiatives included plastic-recycling with community rewards and Holi celebrations in India.[24][25] In the end of 2025, boxer Canelo Álvarez presented charitable sport equipment donations in Mexico City and hometown Guadalajara on behalf of the brand.[26] In 2026, 1win Charity supplied emergency kits for wildfire relief efforts in the Ñuble region of Chile with boxer Andrés Campos.[27]
Sponsorships
In May 2025, 1win signed sponsorship agreements with Canelo Álvarez.[6] Before that, the company signed an agreement with cricketer David Warner,[28][29] and adult performer Johnny Sins.[30] In September 2025, MMA fighter Jon Jones became an ambassador for 1win,[31] and in 2026, also Ilia Topuria[32] and olympic wrestling champion Gable Stevenson.[33] The same year, the company also signed a collaboration with American rapper Tyga and sponsored his private jet flight.[34]
Esports and Dota 2
1win operates esports teams and sponsors events through its 1win Esports division. In Counter-Strike 2, the organization signed Timur "buster" Tulepov and Sanzhar "neaLaN" Ishkakov, joining Vladislav "lattykk" Vydrin, Boris "Ryujin" Kim, and Rassim "Jyo" Valiev.[35]
In 2024–2025, roster changes included the departures of Dmitry "Fishman" Polishchuk and Alexander "Cloud" Zakharov ahead of FISSURE Universe: Episode 4.[36]
In 2024, 1win Esports held three US$100,000 editions of the 1win Series Dota 2: Spring (won by Entity), Summer (won by Team Spirit),[37] and Fall (won by Team Liquid).[38] The organization also hosted a shorter event, the 1win Series Dota 2 Punch, which was won by Chimera Esports.[39]
In June 2026, the company has signed an entire Tundra Esports Dota 2 roster (Pure, bzm, 33, Ari, and Whitemon) to transfer under 1win Esports, along with the team management and coach.[40][41]
