Changes to Valve Tournament Guidelines

Changes have been reported in the guidelines that oversee Valve tournaments. The new modifications dictate that all tournaments that feature Valve games, such as Counter-Strike 2 and Dota 2, are not permitted to have skin gambling/trading sites or case opening sites as sponsors. It is also necessary for tournament organizers to make sure that any logos affiliated with these types of sites are not visible on the official broadcast. This change may seem minor, but it could have significant and ongoing implications.

Update on Tournament Operating Requirements and Limited Game Tournament License

Valve has revised its Tournament Operating Requirements and Limited Game Tournament License, which prohibits the promotion of skin gambling, case-opening, or skin‑trading sites at all CS2 events. As such, sponsorship from these types of sites can no longer be displayed on jerseys, broadcasts, or event materials.

Key Points on the ban

This ban applies to both Ranked and Unranked events that use Valve’s CS2 license. Tournament organizers are not allowed to display or distribute logos, ads, or promotions for case-opening, skin-trading, or skin-gambling sites anywhere in the venue, including team jerseys. They must also ensure that no promotions endorse entities that violate Valve IP or the Steam Subscriber Agreement. The Agreement specifically targets many third‑party skin sites.

Impact on Teams and Sponsors

a number of top-performing CS2 teams currently show off skin-site sponsors on their jerseys. However, under the revised guidelines, these sponsor logos will have to be removed or restructured for any Valve-licensed event. Some teams had early warning about the impending rule change. At the StarLadder Budapest Major, for instance, some teams had already started removing skin sponsor logos from their jerseys.

Wider Context of Skin-Gambling Crackdown

This move by Valve is part of a broader tightening of rules around skins-as-gambling-currency. Regulatory bodies such as the Washington State Gambling Commission and UK authorities are treating tradable skins as items of monetary value, which require gambling licenses when used in games of chance. Starting from November 17, 2025, YouTube will ban content directing viewers to gambling sites using CS2 skins or NFTs, unless those platforms are certified by Google Ads. Twitch has already announced a ban on streaming unlicensed gambling sites and is also cracking down on skin-gambling sponsorships.

Valve’s Stance on CS2 Skin Gambling

Valve has updated its Steam Online Conduct page to confirm that gambling is a prohibited activity. There were concerns about bans on players, but little concrete enforcement against individual players has been seen. Third-party sites continue to operate widely, and skin gambling is still popular. At the same time, Valve continues to generate revenue through loot-box-style case openings, described as a form of gambling and an ‘addictively intentional feature’ by many regulators and lawsuits.

Legal and Reputational Context

In 2025, lawsuits claimed that Counter-Strike’s loot boxes and cosmetics systems contribute to addiction and function like gambling, during which time hundreds of millions of cases are opened each year, with skin valuations amounting to billions of dollars. Legal analysts expect increasing pressure on Valve to restrict automated transfers and marketplace behaviours that allow cash-out and arbitrage, particularly as platforms such as YouTube restrict unregulated skin casinos.
