ESL Bans CS2 Teams From Promoting Skin Gambling and Trading Sponsors

ESL FACEIT Group (EFG) has officially prohibited Counter-Strike 2 teams from promoting skin gambling, case-opening, and skin trading platforms during its tournaments, aligning its commercial rules with Valve's ongoing crackdown on third-party services that interact with players' inventories.

The updated sponsorship policy takes effect ahead of the second ESL Pro Tour season of 2026 and bars organizations from displaying or promoting companies that violate Valve's intellectual property rights. Teams whose branding includes prohibited sponsors will also be required to use an alternative version of their logo or jersey during ESL events.

ESL Strengthens Valve's Existing Restrictions

The rule change builds on Valve's decision in December 2025 to ban professional teams from advertising skin gambling, skin trading, and case-opening websites during official Counter-Strike events. That policy prohibited affected sponsors from appearing on team jerseys, broadcasts, and other tournament-related content.

ESL has now reinforced that position by incorporating similar language into its own rulebook, ensuring teams competing in its tournaments must also comply with the restrictions.

Despite Valve's original policy, several organizations have continued partnerships with skin-related platforms outside official broadcasts. Team Vitality still lists Skin.Club and Skin.Land among its commercial partners, while The MongolZ continues working with CSGO Skins. MOUZ also maintains a partnership with G4Skins, although those brands cannot be promoted during Valve- or ESL-operated competitions.

Gambling Operators Continue to Fill the Sponsorship Gap

While skin gambling companies face tighter restrictions, licensed betting operators continue to play a major role in Counter-Strike sponsorships.

Many of the teams previously associated with skin trading platforms have shifted their tournament branding toward gambling operators. Team Vitality's primary jersey sponsor is Stake, The MongolZ has a long-standing partnership with 1xBet, and MOUZ competes under sponsorship from Fonbet during official events.

The distinction reflects Valve's current policy, which targets businesses that interact with in-game inventories rather than gambling companies themselves. Although betting sponsorships remain common across esports, they continue to face increasing scrutiny from regulators in several jurisdictions, particularly in Europe.

Valve Continues to Face Regulatory Pressure

The latest rule change also comes as Valve faces growing legal and regulatory challenges surrounding Counter-Strike's virtual item ecosystem.

The company is currently defending itself against legal action brought by New York Attorney General Letitia James, who alleges Valve has failed to do enough to prevent illegal skin gambling through third-party platforms. Valve has argued that its terms of service already prohibit those services and that it actively opposes unauthorized use of its intellectual property.

Separately, Valve and several other game publishers, including Riot Games, recently faced regulatory action in Brazil over loot boxes, with authorities arguing that the mechanic can encourage gambling-like behavior among minors.

By tightening sponsorship rules alongside Valve, ESL is further distancing the competitive Counter-Strike ecosystem from skin gambling operators while reinforcing the publisher's efforts to limit their visibility within official esports events.
